168 Driving and Operating
The vehicle may straighten out.Be ready for a second skid if itoccurs.
.Slow down and adjust yourdriving according to weatherconditions. Stopping distancecan be longer and vehiclecontrol can be affected whentraction is reduced by water,snow, ice, gravel, or othermaterial on the road. Learn torecognize warning clues—suchas enough water, ice, or packedsnow on the road to make amirrored surface—and slowdown when you have any doubt.
.Try to avoid sudden steering,acceleration, or braking,including reducing vehicle speedby shifting to a lower gear. Anysudden changes could causethe tires to slide.
Remember: Antilock brakes helpavoid only the braking skid.
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.
{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
(Continued)
Warning (Continued)
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.

when on dry pavement. SeeAntilock Brake System(ABS)0188.
.Allow greater following distanceand watch for slippery spots. Icypatches can occur on otherwiseclear roads in shaded areas.The surface of a curve or anoverpass can remain icy whenthe surrounding roads are clear.Avoid sudden steeringmaneuvers and braking whileon ice.
.Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place andsignal for help. Stay with the vehicleunless there is help nearby.If possible, use RoadsideAssistance. SeeRoadsideAssistance Program0316.Togethelp and keep everyone in thevehicle safe:
.Turn on the hazard warningflashers.
.Tie a red cloth to an outsidemirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
.Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.
.Adjust the climate controlsystem to circulate the airinside the vehicle and set

the fan speed to the highestsetting. See“ClimateControl Systems.”
For more information about CO,
seeEngine Exhaust0182.
To s a v e f u e l , r u n t h e e n g i n e f o rshort periods to warm the vehicleand then shut the engine off andpartially close the window. Movingabout to keep warm also helps.
If it takes time for help to arrive,when running the engine, push theaccelerator pedal slightly so theengine runs faster than the idlespeed. This keeps the batterycharged to restart the vehicle and tosignal for help with the headlamps.Do this as little as possible, tosave fuel.

Parking Assist
If equipped, the Rear Parking Assist(RPA) system uses sensors on therear bumper to assist with parkingand avoiding objects while inR(Reverse).
{Warning
The parking assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that are too
close or too far from the vehicle.
It is not available at speeds
greater than 8 km/h (5 mph). To
prevent injury, death, or vehicle
damage, even with parking assist,
always check the area around the
vehicle and check all mirrors
before backing.
How the System Works
RPA comes on automatically whenthe shift lever is moved intoR(Reverse). A single beep soundsto indicate the system is working.
RPA operates only at speeds lessthan 8 km/h (5 mph).
An obstacle detection is indicatedby beeps. The time between beepsgets shorter as the vehicleapproaches the obstacle. Repeatedbeeps are heard when the distanceis less than 30 cm (12 in).
To b e d e t e c t e d , o b j e c t s m u s t b e a tleast 25 cm (10 in) off the groundand below rear door level. Objectsmust also be within 2.5 m (8 ft) fromthe rear bumper. This distance maybe less during warmer or humidweather.
Turning the System On and Off
The system can be disabled throughthe Driver Information Center (DIC).See“Park Assist”underDriverInformation Center (DIC)0108.
RPA defaults to the on setting eachtime the vehicle is started.

To w i n g a t r a i l e r r e q u i r e s a c e r t a i namount of experience. Thecombination you are driving islonger and not as responsive as the
vehicle itself. Get acquainted withthe handling and braking of the rigbefore setting out for the open road.
The structure, tires, and brakes ofthe trailer must be rated to carry theload. Inadequate trailer equipmentcan cause the combination tooperate in an unexpected or unsafemanner.
Before starting, check all trailer hitchparts and attachments, safetychains, electrical connectors, lamps,tires, and mirrors. Get familiar withthe handling and braking of the rig.If the trailer has electric brakes, startthe combination moving and thenapply the trailer brake controller byhand to be sure the brakes work.
During the trip, check occasionallyto be sure that the load is secureand the lamps and any trailerbrakes still work.
Following Distance
Stay at least twice as far behind thevehicle ahead as you would whendriving the vehicle without a trailer.This can help to avoid heavybraking and sudden turns.
