Other Rainy Weather Tips
Besides slowing down, other wet weather drivingtips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment in good shape.
.Keep the windshield washer fluid reservoir filled.
.Have good tires with proper tread depth.SeeTires on page 7!58.

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.
6-52
4. Reapply the brake pedal. Then apply the parkingbrake and shift into P (Park).
5. Release the brake pedal.
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll.
If the engine has been left running, the vehicle
can move suddenly. You or others could be
injured. To be sure the vehicle will not move, even
when on fairly level ground, always put the shift
lever fully in P (Park) with the parking brake
firmly set.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
2. Start the engine
3. Shift into a gear
4. Release the parking brake
5. Let up on the brake pedal.
6. Drive slowly until the trailer is clear of the chocks.
7. Stop and have someone pick up and storethe chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling atrailer. See this manual's Maintenance Schedule orIndex for more information. Things that are especiallyimportant in trailer operation are automatic transmissionfluid, engine oil, axle lubricant, belts, cooling systemand brake system. It is a good idea to inspect thesebefore and during the trip.
Check periodically to see that all hitch nuts and boltsare tight.

Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil level at eachfuel fill. In order to get an accurate reading, the oil mustbe warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. SeeEngine Compartment Overviewon page 7!16for thelocation of the engine oil dipstick.
1. Turn off the engine and give the oil several minutesto drain back into the oil pan. If this is not done, theoil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towelor cloth, then push it back in all the way. Remove itagain, keeping the tip down, and check the level.
7-17
When to Add Engine Oil
If the oil is below the cross-hatched area at the tipof the dipstick, add at least one quart/liter of therecommended oil. This section explains what kindof oil to use. For engine oil crankcase capacity, seeCapacities and Specifications on page 7!115.
Notice:Do not add too much oil. If the enginehas so much oil that the oil level gets abovethe cross-hatched area that shows the properoperating range, the engine could be damaged.
SeeEngine CompartmentOverviewon page 7!16for the location of theengine oil fill cap.
Add enough oil to put the level somewhere in the properoperating range. Push the dipstick all the way back inwhen through.
7-18
What Kind of Engine Oil to Use
Look for three things:
.GM4718M
This vehicle's engine requires a special oil meetingGM Standard GM4718M. Oils meeting thisstandard may be identified as synthetic. However,not all synthetic oils will meet this GM standard.Use only an oil that meets GM StandardGM4718M.
Notice:Using oils that do not have the GM4718MStandard designation can cause engine damage notcovered by the vehicle warranty.
.SAE 5W-30
SAE 5W-30 is best for the vehicle. These numberson an oil container show its viscosity, or thickness.Do not use other viscosity oils such asSAE 20W-50.
.American Petroleum Institute (API) starburstsymbol
Oils meeting theserequirements should havethe starburst symbol onthe container. This symbolindicates that the oil hasbeen certified by theAmerican PetroleumInstitute (API).
This vehicle's engine was filled at the factory with aMobil 1®synthetic oil meeting all requirements for thisvehicle.
Substitute Engine Oil: When adding oil to maintainengine oil level, oil meeting GM Standard GM4718Mmight not be available. You can add substitute oildesignated SAE 5W-30 with the starburst symbol at alltemperatures. Substitute oil not meeting GM StandardGM4718M should not be used for an oil change.
