222 Driving and Operating
Traction is reduced on hard packedsnow and ice and it is easy to losecontrol. Reduce vehicle speed whendriving on hard packed snowand ice.
{Warning
Driving on frozen lakes, ponds,
or rivers can be dangerous. Ice
conditions vary greatly and the
vehicle could fall through the ice;
you and your passengers could
drown. Drive your vehicle on safe
surfaces only.
Driving in Water
{Warning
Driving through rushing water can
be dangerous. Deep water can
sweep your vehicle downstream
and you and your passengers
could drown. If it is only shallow
water, it can still wash away the
ground from under your tires.
(Continued)
Warning (Continued)
Traction could be lost, and the
vehicle could roll over. Do not
drive through rushing water.
Caution
Do not drive through standing
water if it is deep enough to cover
the wheel hubs, axles, or exhaust
pipe. Deep water can damage the
axle and other vehicle parts.
If the standing water is not too deep,drive slowly through it. At fasterspeeds, water splashes and thevehicle can stall. When goingthrough water, the brakes get wetand it may take longer to stop. See“Driving on Wet Roads”later in thissection.
After Off-Road Driving
Remove any brush or debris thathas collected on the underbody orchassis, or under the hood. Theseaccumulations can be a fire hazard.
After operation in mud or sand,have the brake linings cleaned andchecked. These substances cancause glazing and uneven braking.Check the body structure, steering,suspension, wheels, tires, andexhaust system for damage andcheck the fuel lines and coolingsystem for any leakage.
More frequent maintenance serviceis required. See theMaintenanceSchedule0366.
Driving on Wet Roads
Rain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep-standing or flowing water.

Driving and Operating 223
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Watercan build up under the vehicle'stires so they actually ride on thewater. This can happen if the road iswet enough and you are going fastenough. When the vehicle ishydroplaning, it has little or nocontact with the road.
There is no hard and fast rule abouthydroplaning. The best advice is toslow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wetweather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wipingequipment in good shape.
.Keep the windshield washer fluidreservoir filled.
.Have good tires with propertread depth. SeeTires0316.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or throughmountains is different than drivingon flat or rolling terrain. Tips include:
.Keep the vehicle serviced and ingood shape.
.Check all fluid levels and brakes,tires, cooling system, andtransmission.
.Shift to a lower gear when goingdown steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.

Ignition Positions
The ignition switch has four differentpositions.
To s h i f t o u t o f P ( P a r k ) , t h e i g n i t i o nmust be in ON/RUN or ACC/ACCESSORY and the regular brakepedal must be applied.
0(STOPPINGTHEENGINE/LOCK/OFF) :When the vehicle is stopped,turn the ignition switch to LOCK/OFF to turn the engine off. RetainedAccessory Power (RAP) will remainactive. SeeRetained AccessoryPower (RAP)0237.
This position locks the ignition andsteering wheel. It also locks thetransmission on automatictransmission vehicles. The key canbe removed in LOCK/OFF.
The steering can bind with thewheels turned off center. If thishappens, move the steering wheelfrom right to left while turning thekey to ACC/ACCESSORY. If thisdoes not work, then the vehicleneeds service.
Do not turn the engine off when thevehicle is moving. This will cause aloss of power assist in the brakeand steering systems and disablethe airbags.
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), continue to
firmly apply the brakes andsteer the vehicle to a safelocation.
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 Brake0254.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,and must be shut off while driving,turn the ignition to ACC/ACCESSORY.
On vehicles with an automatictransmission, the shift lever must bein P (Park) to turn the ignition switchto LOCK/OFF.

Torque Lock
If you are parking on a hill and youdo not shift the transmission intoP(Park) properly, the weight of thevehicle may put too much force onthe parking pawl in thetransmission. You may find it difficultto pull the shift lever out of P (Park).This is called torque lock. Toprevent torque lock, set the parkingbrake and then shift into P (Park)properly before you leave the driverseat. To find out how, seeShiftingInto Park0238.
When you are ready to drive, movethe shift lever out of P (Park) beforeyou release the parking brake.
If torque lock does occur, you mayneed to have another vehicle pushyours a little uphill to take some ofthe pressure from the parking pawlin the transmission. You will then beable to pull the shift lever out ofP(Park).
Shifting out of Park
This vehicle is equipped with anelectronic shift lock release system.The shift lock release isdesigned to:
.Prevent ignition key removalunless the shift lever is inP(Park).
.Prevent movement of the shiftlever out of P (Park), unless theignition is in ON/RUN and theregular brake pedal is applied.
To s h i f t o u t o f P ( P a r k ) :
1. Apply the brake pedal.
2. Press the button on the shiftlever.
3. Move the shift lever to thedesired position.
If you still are unable to shift out ofP(Park):
1. Ease the pressure on the shiftlever.
2. While holding down the brakepedal and pressing the shiftlever button, move the shiftlever all the way into P (Park).
3. While holding the shift leverbutton, move the shift lever tothe desired position.
If you are still having a problemshifting, then have the vehicleserviced soon.
This vehicle may have the SafetyBelt Assurance System, which mayprevent the vehicle from shifting outof P (Park). SeeSafety BeltMessages0136.
Parking
If the vehicle has a manualtransmission, before you get out ofthe vehicle, move the shift lever intoR(Reverse), and firmly apply theparking brake. Once the shift leverhas been placed into R (Reverse)with the clutch pedal pressed in,turn the ignition key to LOCK/OFF,remove the key and release theclutch.

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 lights will flash on thewindshield. Also, eight rapidhigh-pitched beeps will sound fromthe front. When this Collision Alertoccurs, the brake system mayprepare for driver braking to occur
more rapidly which can cause abrief, mild deceleration. Continue toapply the brake pedal as needed.Cruise control may be disengagedwhen the Collision Alert occurs.
Tailgating Alert
The vehicle ahead indicator willdisplay amber when you arefollowing a detected vehicle aheadmuch too closely.
Selecting the Alert Timing
The Collision Alert control is on the
steering wheel. Press[to set the
FCA timing to Far, Medium, Near,or Off. The first button press showsthe current setting on the DIC.Additional button presses willchange this setting. The chosensetting will remain until it is changedand will affect the timing of both theCollision Alert and the TailgatingAlert features. The timing of both
alerts will vary based on vehiclespeed. The faster the vehicle speed,the farther away the alert will occur.Consider traffic and weatherconditions when selecting the alerttiming. The range of selectable alerttiming may not be appropriate for alldrivers and driving conditions.
Unnecessary Alerts
FCA may provide unnecessaryalerts for turning vehicles, vehiclesin other lanes, objects that are notvehicles, or shadows. These alertsare normal operation and thevehicle does not need service.
Cleaning the System
If the FCA system does not seem tooperate properly, cleaning theoutside of the windshield in front ofthe rearview mirror, and cleaning theheadlamps, may correct the issue.
Lane Departure
