Safety or driver assistance features are no substitute for the driver’s responsibility to operate the vehicle in a safe manner. The driver should remain attentive to traffic, surroundings and road conditions at all times. Read your Owner’s Manual for important feature limitations and information.
SAFETY ALERT SEAT – The driver’s seat pulses — left side, right side, or simultane-ously — to alert the driver of the direction of potential hazards.
 Audible  notification  may be selected  instead of Safety  Alert Seat pulsing  notifica-tion. To change the alert setting, go to Settings > Vehicle > Collision/Detection Systems > Alert Type.
FORWARD COLLISION ALERT – The Vehicle Ahead Indicator is green when a vehicle is detected and is amber when following a vehicle ahead much too closely. When approaching  a vehicle  directly  ahead too rapidly,  a red  alert  flashes  on the windshield  and the Safety  Alert Seat pulses  or rapid  beeps  sound  (if selected). 
Press the Collision Alert button on the left side of the steering wheel to set the alert timing to Far, Medium, or Near.
This is also the Adaptive Cruise ControlF
following gap setting. The setting is dis-played on the Driver Information Center.
To set the Forward Collision Alert and Forward Automatic Braking systems to Alert  and Brake,  Alert, or Off,  go to Settings > Vehicle > Collision/Detection Systems > Forward Collision System.

INTEGRATED TRAILER BRAKE CONTROL (ITBC)
The traction control system limits wheelspin and the StabiliTrak® stability control  
system  assists with  directional  control of the  vehicle  in difficult   driving conditions. Both systems turn on automatically every time the vehicle is started.
Turn off traction control if the vehicle is stuck and rocking the vehicle is required.
Press the Traction Control/StabiliTrak Off button on the left side of the instru-ment  panel  to turn  traction  control off or on.  The Traction  Control Off light  will  
illuminate  on the  instrument  cluster when the  system  is off.
See Driving and Operating in your Owner’s Manual.
TRACTION CONTROL AND STABILITRAK SYSTEMS
The Low Tire Pressure 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 listed on the Tire and Loading Information label, located below the driver’s door latch. Current tire pressures can be viewed on the Driver Information Center.
The Tire  Fill Alert  provides  visual  and audible  alerts to help  when  inflating  a tire  to the recommended  tire pressure  (does not apply  to spare  tire). When  the recommended pressure  is reached,  the horn  sounds  and the turn  signals  change  from flashing  to solid. 
Refer to your Owner’s Manual for information about normal monthly tire maintenance.
See Vehicle Care in your Owner’s Manual.
TIRE PRESSURE MONITOR WITH TIRE FILL ALERT
The Tow/Haul Mode adjusts the transmission shifts to reduce shift cycling, such as when towing or hauling heavy loads or driving on steep grades.
Press the Tow/Haul Mode button on the end of the shift lever to turn the  
system  on or off.
