256 Driving and Operating
{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. SeeTires0397.
.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.

Driving and Operating 257
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering. Always have the
engine running and the vehicle
in gear.
.Drive at speeds that keep thevehicle in its own lane. Do notswing wide or cross thecenter line.
.Be alert on top of hills;something could be in your lane(e.g., stalled car, accident).
.Pay attention to special roadsigns (e.g., falling rocks area,winding roads, long grades,passing or no-passing zones)and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires andthe road creates less traction orgrip, so drive carefully. Wet ice canoccur at about 0 °C (32 °F) whenfreezing rain begins to fall. Avoiddriving on wet ice or in freezing rainuntil roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Acceleratingtoo quickly causes the wheels tospin and makes the surfaceunder the tires slick.
.Turn on Traction Control. SeeTr a c t i o n C o n t r o l / E l e c t r o n i cStability Control0295.
.The Antilock Brake System(ABS) improves vehicle stabilityduring hard stops, but thebrakes should be applied soonerthan when on dry pavement.SeeAntilock Brake System(ABS)0292.
.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 Program0476.Togethelp and keep everyone in thevehicle safe:
.Turn on the hazard warningflashers.
.Tie a red cloth to an outsidemirror.

gasoline. Try pushing theaccelerator pedal all the way tothe floor and holding it therewhile holding the key in STARTfor up to 15 seconds. Wait atleast 15 seconds between eachtry, to allow the cranking motorto cool down. When the enginestarts, let go of the key andaccelerator. If the vehicle startsbriefly but then stops again, dothe same thing. This clears theextra gasoline from the engine.Do not race the engineimmediately after starting it.Operate the engine andtransmission gently until the oilwarms up and lubricates allmoving parts.
Fast Idle System
If equipped, this feature is availableonly with cruise control. The manualfast idle switch is operated using thecruise control buttons on the leftside of the steering wheel.
This system can be used toincrease engine idle speedwhenever the following conditionsare met:
.The parking brake is set.
.The brake pedal is not pressed.
.The vehicle must not be movingand the accelerator must not bepressed.
To c o n t r o l t h e f a s t i d l e :

Kickdown Mode
If equipped, the accelerator pedalprovides an additional downshiftafter pressing through the kickdownfeature.
It requires extra pedal pressure nearthe end of its travel to engage.
Manual Mode
Range Selection Mode
If equipped, Range Selection Modehelps control the vehicle'stransmission and vehicle speedwhile driving downhill or towing atrailer by letting you select a desiredrange of gears.
To u s e t h i s f e a t u r e :
1. Move the shift lever toL(ManualMode).
2. Press the plus/minus buttonson the shift lever to select thedesired range of gears forcurrent driving conditions.
With an 8-speed automatictransmission, hold the plus/minusbuttons on the shift lever to selectthe highest or lowest rangeavailable for the current vehiclespeed.
When the shift lever is moved fromD(Drive) to L(Manual Mode), anumber displays next to the L,indicating the current transmissionrange.
This number is the highest gear thatthe transmission will command whileoperating in L (Manual Mode). Allgears below that number areavailable. As driving conditionschange, the transmission canautomatically shift to lower gears.For example, when L5 is selected,1(First) through 5(Fifth) gears areautomatically shifted by thetransmission, but 6 (Sixth) cannot beused until the plus/minus button onthe shift lever is used to change tothe range.
