Driving On Grades
Reduce speed and shift to a lower gearbeforestartingdown a long or steep downgrade. If the transmission isnot shifted down, the brakes might get hot and nolonger work well.
Vehicles can tow in D (Drive). Shift the transmission toa lower gear if the transmission shifts too often underheavy loads and/or hilly conditions.
The tow/haul mode may be used if the transmissionshifts too often. SeeTow/Haul Mode on page 3!36.
When towing at high altitude on steep uphill grades,consider the following: Engine coolant will boil at alower temperature than at normal altitudes. If the engineis turned off immediately after towing at high altitude onsteep uphill grades, the vehicle may show signs similarto engine overheating. To avoid this, let the engine runwhile parked, preferably on level ground, with theautomatic transmission in P (Park) for a few minutesbefore turning the engine off. If the overheat warningcomes on, seeEngine Overheating on page 7!34.
Parking on Hills
{WARNING:
Parking the vehicle on a hill with the trailer
attached can be dangerous. If something goes
wrong, the rig could start to move. People can be
injured, and both the vehicle and the trailer can be
damaged. When possible, always park the rig on
a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift intoP (Park) yet. Turn the wheels into the curb if facingdownhill or into traffic if facing uphill.
2. Have someone place chocks under the trailerwheels.
3. When the wheel chocks are in place, release theregular brakes until the chocks absorb the load.

Automatic Transmission Fluid
When to Check and Change Automatic
Transmission Fluid
It is usually not necessary to check the transmissionfluid level. The only reason for fluid loss is atransmission leak or overheating the transmission.If you suspect a small leak, then use the followingchecking procedures to check the fluid level. However,if there is a large leak, then it may be necessary to havethe vehicle towed to a dealer/retailer service departmentand have it repaired before driving the vehicle further.
Notice:Use of the incorrect automatic transmissionfluid may damage the vehicle, and the damages maynot be covered by the vehicle's warranty. Alwaysuse the automatic transmission fluid listed inRecommended Fluids and Lubricants on page 8!10.
Change the fluid and filter at the intervals listed in theMaintenance Schedule. SeeScheduled Maintenanceo n p a g e 8!3. Be sure to use the transmission fluidlisted inRecommended Fluids and Lubricantsonpage 8!10.
How to Check Automatic Transmission
Fluid
Notice:Too much or too little fluid can damage yourtransmission. Too much can mean that some of thefluid could come out and fall on hot engine parts orexhaust system parts, starting a fire. Too little fluidcould cause the transmission to overheat. Be sureto get an accurate reading if you check yourtransmission fluid.
Before checking the fluid level, prepare the vehicle asfollows:
1. Start the engine and park the vehicle on a levelsurface. Keep the engine running.
2. Apply the parking brake and place the shiftlever in P (Park).
3. With your foot on the brake pedal, move the shiftlever through each gear range, pausing for aboutthree seconds in each range. Then, move the shiftlever back to P (Park).
7-24

{WARNING:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them.
If you do, you can be burned.
Do not run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
Notice:Using coolant other than DEX-COOL®cancause premature engine, heater core, or radiatorcorrosion. In addition, the engine coolant couldrequire changing sooner, at 50 000 km (30,000 miles)or 24 months, whichever occurs first. Any repairswould not be covered by the vehicle warranty.Always use DEX-COOL®(silicate-free) coolantin the vehicle.
Engine Coolant
The cooling system in the vehicle is filled withDEX-COOL®engine coolant. This coolant is designedto remain in the vehicle for five years or 150,000 miles(240 000 km), whichever occurs first.
The following explains the cooling system and how tocheck and add coolant when it is low. If there is aproblem with engine overheating, seeEngineOverheating on page 7!34.
7-29

4. With the coolant surge tank pressure cap off, startthe engine and let it run until you can feel theupper radiator hose getting hot. Watch out for theengine cooling fan.
By this time, the coolant level inside the coolantsurge tank may be lower. If the level is lower, addmore of the proper mixture to the coolant surgetank until the level reaches the FULL COLD mark.
5. Replace the pressure cap. Be sure the pressurecap is hand-tight and fully seated.
6. Verify coolant level after engine is shut off and thecoolant is cold. If necessary, repeat coolant fillprocedure Steps 1 through 6.
Notice:If the pressure cap is not tightly installed,coolant loss and possible engine damage mayoccur. Be sure the cap is properly and tightlysecured.
Engine Overheating
The vehicle has several indicators to warn of engineoverheating.
There is a coolant temperature gage on your vehicle'sinstrument panel. SeeEngine Coolant TemperatureGage on page 4!35.
In addition, ENGINE OVERHEATED STOP ENGINE,ENGINE OVERHEATED IDLE ENGINE, and a ENGINEPOWER IS REDUCED message comes on in the DriverInformation Center (DIC) on the instrument panel. SeeDIC Warnings and Messages on page 4!48.
You may decide not to lift the hood when this warningappears, but instead get service help right away. SeeRoadside Service on page 9!8.
