If the vehicle must be shut off in anemergency:
1. Brake using a firm and steadypressure. Do not pump thebrakes repeatedly. This maydeplete power assist, requiringincreased brake pedal force.
2. Shift the vehicle to N (Neutral).This can be done while thevehicle is moving. After shiftingto N (Neutral), firmly apply thebrakes and steer the vehicle toasafelocation.
3. Come to a complete stop. Shiftto P (Park) with an automatictransmission, or Neutral with amanual transmission. Turn theignition to LOCK/OFF.
4. Set the parking brake. SeeParking Brake0196.

{Warning
Cruise control can be dangerous
where you cannot drive safely at
asteadyspeed.Donotuse
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If the vehicle's Traction ControlSystem (TCS) or StabiliTrak systembegins to limit wheel spin whileusing cruise control, the cruisecontrol will automatically disengage.

Warning (Continued)
closely, FCA may not provide a
warning with enough time to help
avoid a crash. It also may not
provide any warning at all. FCA
does not warn of pedestrians,
animals, signs, guardrails,
bridges, construction barrels,
or other objects. Be ready to take
action and apply the brakes. See
Defensive Driving0172.
FCA can be disabled with the FCAsteering wheel control.
Detecting the Vehicle Ahead
FCA warnings will not occur unlessthe FCA system detects a vehicleahead. When a vehicle is detected,the vehicle ahead indicator willdisplay green. Vehicles may not be
detected on curves, highway exitramps, or hills, due to poor visibility;or if a vehicle ahead is partiallyblocked by pedestrians or otherobjects. FCA will not detect anothervehicle ahead until it is completelyin the driving lane.
{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.
Collision Alert
When your vehicle approachesanother detected vehicle too rapidly,the red FCA display on top of theinstrument panel to the right of thesteering wheel will flash. Also,several rapid high-pitched beeps willsound from the front. When thisCollision Alert occurs, the brakesystem may prepare for driverbraking to occur more rapidly whichcan cause a brief, mild deceleration.Continue to apply the brake pedalas needed. Cruise control may bedisengaged when the Collision Alertoccurs.
Tailgating Alert
The red FCA display will staycontinuously illuminated when youare following a detected vehicleahead much too closely.
