Four wheel Anti-Lock Braking System - A break in the weather. When you need to stop fast, you can't have it depend on the road and/or weather conditions. Four wheel ABS Brakes pump the brakes more quickly than a driver could, so the wheels won't lock up even if you slam on the brakes. That results in significantly reducing stopping distances and improved steering control. Get the stopping power you need with Four Wheel ABS Brakes.
4-wheel disc brakes - covered all the way around. The most basic safety feature of your vehicle is the brakes, and 4-wheel disc brakes have you covered from front to back. Instead of being located on just the front wheels, there are discs on the rear wheels as well, increasing your vehicles ability to slow down quickly without over-heating the braking system. Get stopping power that doesn’t quit with 4-wheel disc brakes.
6 airbags - Air on the safe side. Collisions are often unexpected, but you have the peace of mind of extra protection should they occur. When used in combination with your seatbelt, airbags greatly reduce the possibility of serious injury, compared to a vehicle without airbags. Be prepared for the worst with 6 airbags.
Airbag occupancy sensor - people smart. Airbag occupancy sensor is a smarter way to protect your passenger. Using a sensor to determine the size and position of the passenger, it will deploy the correct airbags with the right intensity in case of a collision. Airbag occupancy sensor offers better protection to the smaller passengers and more peace of mind for you.
Auto high-beam headlamps. Safety equipment as considerate as you are. With auto high-beam headlamps, you don’t have to manually switch from high to low and back again every time a vehicle approaches. They automatically adjust intensity in response to surrounding traffic - whether that's oncoming vehicles or while you're following a vehicle. Auto high-beam headlamps promote highbeam use for increased visibility and safety for you while reducing the intensity and glare for them.
Fully automatic headlamp control - convenience you can see. Forgetting to turn on your lights is an easy mistake to make, but it can be a safety hazard for you and others. Forget all your worries with fully automatic headlamp control. The built-in sensor turns the headlights on or off based the level of ambient light so you don’t have to take your eyes off the road to find the controls. Plus you don't have to worry about accidentally leaving the lights on and draining your battery. Day or night, automatic headlamp control is the right amount of light.
Predictive brake assist - Be prepared for your big brake. Predictive brake assist monitors the available distance in front of you compared to your vehicles speed. If your speed exceeds the required distance to stop short of a collision, it readies your brakes to apply maximum stopping force when you use them. Predictive brake assist helps see to it that you stop.
They help define the height of the vehicle in the dark.
Pickup box cargo light - Light it up to load it up. The sun may have set, but the work ain’t done. Beat back the dark with pickup box cargo light. It provides the light you need so you can keep loading up when the sun is down. Pickup box cargo light can’t lift the cargo for you, but it can show you the way.
Configurable gauges - Your ride, your view. Configurable gauges allow you to choose the information you want to see, where you want to see it. With a clear view of the information you need from the configurable gauges, you have one less thing on your mind.
Curtain first and second row overhead airbags - Protection from the top down, inside and out. In the event of a collision the curtain airbags cover the windows, keeping you and your passengers in the vehicle and preventing outside glass and debris from entering. When used in combination with your seatbelt, airbags greatly reduce the possibility of serious injury, compared to a vehicle without airbags. Be prepared for the worst with Curtain first and second row overhead airbags
Delay-off headlamps - Extra time in the light. You don’t have to stumble around in the dark after you get out, thanks to delay-off headlamps. When the vehicle is turned off the headlamps stay on so you can see where you’re going once you get out. They will then turn off automatically after a pre-set amount of time. When it comes to walking from your car at night, delay-off headlamps are a bright idea.
Digital/analog instrumentation - A dashboard revolution - Get the nostalgia of traditional and the accuracy of the modern with digital/analog instrumentation. Combining analog style with digital gives you the best of both worlds. We love our technology, but there's nothing quite like burying the needle. That’s why there’s digital/analog instrumentation.
Convex spotter driver side door mirror - get the bigger picture. An additional mirror to the standard driver side mirror, convex spotter mirror has a domed surface for a larger field of vision. The more you can see, the better decisions you can make about whether it’s safe to back out or change lanes. See what you’ve been missing with convex spotter driver side door mirror.
Driver front impact airbag - Safer on all fronts. Driver front-impact airbag is designed to decrease the risk of serious head, chest and knee injury that can be happen when your body is thrown with force against the steering wheel or dashboard. When used in combination with your seatbelt, airbags greatly reduce the possibility of serious injury, compared to a vehicle without airbags. Be prepared for the worst with driver front-impact airbag.
Anti-roll control - Don’t get tipsy. While you appreciate the higher viewpoint of your vehicle, the high center of gravity can make it harder to maintain control during fast cornering maneuvers. Anti-roll control senses and corrects possible rollover situations by employing the braking and engine control systems when needed. Keep all four wheels on the ground with anti-roll control.
Fade dome light - Don’t be left in the dark. Fade dome light ensures that when you’re putting your stuff down, or gathering it up, there will be light. It remains on for several seconds after the doors have been shut or the vehicle turned off and then dims, making it easier to handle all the extra stuff you’ve brought along. Fade dome light make your cargo a little lighter.
Following distance alert. Create a safe space. Following distance alert allows you to select a comfortable gap between you and the vehicle ahead - then monitors and alerts you when the gap is too close. Giving yourself time and space means a safer drive thanks to following distance alert.
Forward collision mitigation - Forward thinking. You look away for just a second and suddenly the vehicle in front of you has stopped. That's when the forward collision mitigation system comes to life. When it senses an impending impact, it will activate a combination of features to help prevent or reduce the severity of an accident. Forward collision mitigation is always looking ahead.
Pedestrian impact prevention - An extra step toward safety. Pedestrians don't always stop, look, and listen, but with Pedestrian Impact Prevention, your vehicle is equipped to better see them and avoid them. This system constantly monitors the road ahead to identify and track pedestrians. It projects that image to an interior display screen, AND should an impact become likely, Pedestrian impact prevention takes steps to avoid a collision.
Front camera with washer - A clearer view of what lay before you! The front camera helps you see obstacles and hazards you might have missed by showing enhanced images of what is ahead. Even if there are sloppy conditions, the washer keeps the camera's view clean. Front camera with washer is an extra set of eyes that's both convenient and safe.
Front seatbelt pretensioners - tighten up. When you stop suddenly front seatbelt pretensioners make sure your body doesn’t keep going. They remove any slack in the seatbelt when you hit the brakes or are involved in a collision so you stay in place. Stay strapped in with front seatbelt pretensioners.
Rear camera - Watching your back! The rear camera helps you see obstacles and hazards you otherwise couldn't by showing enhanced images of what is behind you. The rear camera is an extra set of eyes that's both convenient and safe.
Aerial View Camera - Be above the fray. Aerial View Camera makes low speed maneuvers such as parking or reversing easier than ever. By using a composite image from cameras positioned around the vehicle to give you a top-down view, you can see all the obstacles in your way. Thanks to Aerial View Camera, taking it from the top means doing it once.
Head-up display - Keep your head up! You don't have to take your eyes off of the road to get information from your dashboard anymore. With head-up display, important driving information - like speed and RPM's - displays on your windshield in your line of sight. Because when you're driving, the most important information lies on the road ahead. Keep your eyes on the road with head-up display.
This safety feature is more easily visible to following drivers and helps them react quicker to a slowing or stopped vehicle.
Hill descent control - Give your brakes a break. When you’re off-roading down a steep grade, you want to worry about navigating the obstacles, not riding the brakes. Hill descent control automatically maintains a safe speed so you can concentrate on what your hands are doing with the wheel rather than what your foot is doing with the brake. When it’s going down, hill descent control makes sure you’re prepared.
Hill hold control - Don’t go back. You know the feeling - you're stopped on a hill and you’re worried about your vehicle rolling backwards when you release the brakes. This is even more worrisome when you’re towing. With hill hold control, the vehicle automatically applies brake force to prevent itself from rolling back. So whether you’re towing a heavy load or simply stopped on a steep incline, hill hold control keeps you on the up and up.
Illuminated entry - see what you’re getting into. Take away any potential surprises with illuminated entry. It lights the interior before you open the door, and stays on for a period of time after the door is closed making it easier to get in after dark, and to see if anyone might be lurking inside. Get added safety and convenience from illuminated entry.
Ignition immobilizer - Theft is a non-starter. You can feel more secure about your vehicle being there when you come back. Ignition immobilizer is a passive security system consisting of a transmitter in the ignition key and a sensor located in the vehicle. If both are not present or do not recognize each other, the vehicle will not start. Ignition immobilizer a sure-fire way to prevent the theft of your vehicle.
LED brake lights - Stand out in back. LED brake lights give you an edge on safety. They light up faster and are brighter than incandescent bulbs, giving you greater visibility sooner to the cars behind you. The faster they know you’re stopping, the safer everyone is, especially at night. LED bulbs are also longer lasting and more efficient than traditional bulbs. Speed is of the essence with LED brake lights.
LED daytime running lights - Brighten your day. LED daytime running lights increase your visibility to oncoming traffic and in adverse weather conditions, so you can be seen and be safe. LED lights are also brighter and more efficient that incandescent bulbs, for even greater visibility to other drivers. Stand out all the time, with LED daytime running lights.
LED fog lights - Clearly better. When the haze settles in, LED fog lights are ready to make short work of it. They make driving fog-covered roads less stressful by giving you greater visibility to other drivers, and of what’s ahead. When things get hazy, clear it up with LED fog lights.
LED low and high beam headlamps - Light up the night. LED low and high beam headlamps produce an intense bluish-white light that more closely resembles natural daylight. In turn, you get a clearer view of the road ahead after the sun goes down. LED low and high beam headlamps are the perfect accessory for going out at night
Lane departure warning - Keep it between the lines. It only takes a moment of inattention for your vehicle to drift. With lane departure warning, your vehicle lets you know when you've unintentionally left your lane. Lane departure warning is an extra level of safety for you and those around you.
Left side camera - Sidelong look. Left side camera displays images from the driver side of your vehicle on a central display screen. It's a second set of eyes for a clearer view, making certain maneuvers that much safer. Left side camera helps you make the right move.
Manual rear child safety door locks - Keep it all inside. Manual rear child safety locks help prevent a kid’s fidgets from becoming a big problem. Because if kids can touch it, they want to play with it, and that includes door handles and locks. When enabled, the safety locks stop the doors from being opened from the inside. Manual rear child safety door locks replace mistakes with peace of mind.
This headlamp layout provides improved lighting due to the dedicated task assigned to each bulb.
The combination of seatbelt and airbags greatly reduce the possibility of serious injury occupants may sustain in the event of a crash, compared to a vehicle without airbags.
Pickup box camera - Don't lose sight. Being distracted by the worry of whether or not your load is staying in place is no way to drive. Keep an eye on your cargo with this camera that displays the truck bed contents on the interior display, so you can forge ahead confidently. With the pickup box camera you can be sure you don’t lose your load.
Projector beam headlamps - To a brighter tonight. Push back the curtains of the night with the Projector beam headlamps. They focus light in a precise pattern, projecting it downward and onto the roadway for excellent visibility and better range than conventional headlamps. See what is coming more clearly, with the Projector beam headlamps.
Rain detecting wipers - rain, rain, go away. When it starts to pour, the last thing you want to do is take your eyes off the road to find the windshield wiper switch; not to mention constantly adjusting the wipers as the rain gets heavier or lightens up. Rain detecting wipers take care of it for you. They use sensors to measure moisture hitting the windshield and adjust the wiper speed accordingly. Rain detecting wipers help you see clearly, automatically.
Rear collision warning - It has your back. This system uses sensors to monitor the area behind you. If it senses an impending crash, it alerts you so you can take steps to prevent a collision or reduce the severity of it. Rear collision warning, a second set off eyes watching over you.
The additional chest coverage provides upper body support during a collision.
Remote activated perimeter approach lighting - See what you’re getting into. Approaching your vehicle in the dark can be treacherous without remote activated perimeter approach lighting.

Whether it’s your teen-aged driver or a valet, you can help ensure they’re driving safely with restricted driving mode.
Tire specific low air pressure warning - A heads up when you’re down. Consider tire specific low air pressure warning a performance feature.

When a tire is running low, a warning light appears so you know which specific wheel it is and can attend to the problem. Get the most performance from your tires thanks to tire specific low air pressure warning.
Blind spot warning - Protect your blind side. You checked the mirror, looked over your shoulder and still nearly collided with the car next to you. Blind spot warning alerts you to the presence of a vehicle to your sides or rear so you know if you're about to make an unsafe lane change. Replace fear and uncertainty with confidence and safety with blind spot warning.
Turn signal indicator in the driver side mirror - another sign you’re moving on. Turn signal indicator in the driver door mirror makes it easier for other drivers to see your intentions. A turn signal flasher is incorporated in the surface of the mirror or built into the mirror housing, so even if they can’t see the back of your vehicle they can still see your signal. Make sure they can see the change coming with turn signal indicator in the driver side mirror.
Front and rear parking sensors - Park like a pro! Using front and rear parking sensors low speed maneuvers such as parking or reversing are easier than ever. So back into that parking spot confidently. Parallel park without the bumper taps! Now any spot is the perfect spot when your have front and rear parking sensors.

This problem is solved by using a video feed from the back of the vehicle - different from the back up camera - in order to show you what you need to see while you drive. With the video-feed rear view mirror, nothing sits between you and a clear view.
