The Low Tire Pressure warning light on the instrument cluster illuminates when one or more of the vehicle’s tires is significantly underinflated. Fill the tires to the proper tire pressures. The proper tire pressures for the vehicle are listed on the T\
ire and Loading Information label, located below the driver’s door latch. Current tir\
e pressures can be viewed in the Driver Information Center.
Tire pressure is affected by cold weather and distance driven. If the low tire pressure
warning light illuminates when the vehicle is first started in cooler temperatures and then turns off as the vehicle is driven, check for the proper tire pressures.\
Refer to your Owner Manual for additional information about normal monthly tire maintenance.

Driver Assistance Systems
The driver assistance systems use advanced technologies to help avoid collisions by
providing visual and audible alerts under some imminent collision conditions.
Forward Collision AlertF – When approaching a vehicle directly ahead too quickly, the system flashes a visual alert and pulses the Safety Alert SeatF. See Safety Alert Seat.
The Vehicle Ahead indicator will illumi-nate in green on the instrument cluster when a vehicle is detected and will illuminate in amber when following a vehicle ahead too closely. If your vehicle approaches another vehicle too rapidly, six red lights will flash on the windshield and the Safety Alert Seat will pulse.
Press the Collision Alert button on the left side of the steering wheel to set the alert sensitivity to Far, Medium, Near, or Off.
Lane Departure WarningF – When crossing a detected lane marking without using a turn signal, the system flashes an amber visual alert on the instrument cluster and pulses the left or right side of the Safety Alert SeatF. See Safety Alert Seat.
Press the Lane Departure Warning button on the center of the instrument panel to turn the system on or off.
Safety Alert SeatF – The driver’s seat pulses, left or right, or simultaneously, alerting the driver of potential hazards.
Audible notification may be selected instead of Safety Alert Seat pulsing notification. To change the alert setting, go to Settings > Vehicle > Collision/Detection\
Systems > Alert Type
Rear Vision Camera – Provides a view directly behind the vehicle when backing up.
To turn the Rear Vision Camera Guidelines or Rear Park Assist Symbols on or off, go to Settings > Rear Camera.
Front and/or Rear Parking Assist – During low-speed parking maneuvers, the system provides “distance to closest object” information in the Customizable Driver Display and a caution symbol on the Rear Vision Camera. When the vehicle should be stopped immediately to avoid a colli-sion, a continuous audible tone sounds or the Safety Alert SeatF pulses. See Safety Alert Seat.
To turn the system on or off, press the Parking Assist button on the center of the instrument panel.
