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 Overview on page 6-12forthe location 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.
6-13

{WARNING:
Operating the engine with the air cleaner/filter off
can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
flames if the engine backfires. If it is not there and
the engine backfires, you could be burned. Do not
drive with it off, and be careful working on the
engine with the air cleaner/filter off.
Notice:If the air cleaner/filter is off, a backfire cancause a damaging engine fire. And, dirt caneasily get into the engine, which will damage it.Always have the air cleaner/filter in place when youare driving.
Automatic Transmission Fluid
When to Check and Change Automatic
Transmission Fluid
A good time to check the automatic transmission fluidlevel is when the engine oil is changed.
Change the fluid and filter at the intervals listed inScheduled Maintenance on page 7-3, and be sure touse the transmission fluid listed inRecommended Fluidsand Lubricants on page 7-8.
6-19

How to Check Automatic
Transmission Fluid
Because this operation can be a little difficult, you maychoose to have this done at the dealer/retailer servicedepartment.
If you do it yourself, be sure to follow all the instructionshere or you could get a false reading on the dipstick.
Notice:Too much or too little fluid can damageyour transmission. Too much can mean that someof the fluid could come out and fall on hot engineparts or exhaust system parts, starting a fire.Too little fluid could cause the transmission tooverheat. Be sure to get an accurate reading if youcheck your transmission fluid.
Wait at least 30 minutes before checking thetransmission fluid level if you have been driving:
•When outside temperatures are above 32°C (90°F).
•At high speed for quite a while.
•In heavy traffic — especially in hot weather.
•While pulling a trailer.
To get the right reading, the fluid should be atnormal operating temperature, which is 82°C to 93°C(180°F to 200°F).
Get the vehicle warmed up by driving about 24 km(15 miles) when outside temperatures are above10°C (50°F). If it is colder than 10°C (50°F), you mayhave to drive longer.
Checking the Fluid Level
Prepare the vehicle as follows:
1. Park the vehicle on a level place. Keep the enginerunning.
2. With the parking brake applied, place the shift leverin 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, positionthe shift lever in P (Park).
4. Let the engine run at idle for three to five minutes.
Then, without shutting off the engine, follow these steps:
1. Locate the transmission fluid cap which is locatednext to the radiator hose and below the engine aircleaner/filter assembly on the driver side of thevehicle. The cap is marked TRANS FLUID.SeeEngine Compartment Overview on page 6-12for more information on location.
2. After removing the engine air cleaner/filter assemblyto reach the transmission fluid cap, turn the capcounterclockwise to remove. Pull out the dipstickand wipe it with a clean rag or paper towel.
6-20

3. Push it back in all the way, wait three seconds, andthen pull it back out again.
4. Check both sides of the dipstick and readthe lower level. The fluid level must be in thecross-hatched area.
5. If the fluid level is in the acceptable range, push thedipstick back in all the way and turn the handleclockwise.
6. Reinstall the engine air cleaner/filter assembly.
How to Add Automatic Transmission
Fluid
Refer to the Maintenance Schedule to determine whatkind of transmission fluid to use. SeeRecommendedFluids and Lubricants on page 7-8.
If the fluid level is low, add only enough of the properfluid to bring the level into the cross-hatched area onthe dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at thedipstick hole to bring it to the proper level.
It does not take much fluid, generally less thanone pint (0.5 L). Do not overfill.
Notice:Use of the incorrect automatic transmissionfluid may damage the vehicle, and the damagesmay not be covered by the vehicle’s warranty.Always use the automatic transmission fluid listedinRecommended Fluids and Lubricants on page 7-8.
3. After adding fluid, recheck the fluid level asdescribed under “How to Check AutomaticTransmission Fluid,” earlier in this section.
4. When the correct fluid level is obtained, pushthe dipstick back in all the way and turn thehandle clockwise.

Starter Switch Check
{WARNING:
When you are doing this inspection, the vehicle
could move suddenly. If the vehicle moves, you or
others could be injured.
1. Before starting this check, be sure there is enoughroom around the vehicle.
2. Firmly apply both the parking brake and the regularbrake. SeeParking Brake on page 3-30.
Do not use the accelerator pedal, and be ready toturn off the engine immediately if it starts.
3. Try to start the engine in each gear. The vehicleshould start only in P (Park) or N (Neutral). If thevehicle starts in any other position, contactyour dealer/retailer for service.

Mechanism Check
{WARNING:
When you are doing this check, the vehicle could
begin to move. You or others could be injured and
property could be damaged. Make sure there is
room in front of the vehicle in case it begins to roll.
Be ready to apply the regular brake at once
should the vehicle begin to move.
Park on a fairly steep hill, with the vehicle facingdownhill. Keeping your foot on the regular brake, set theparking brake.
•To check the parking brake’s holding ability:
With the engine running and the transmissionin N (Neutral), slowly remove foot pressure from theregular brake pedal. Do this until the vehicle isheld by the parking brake only.
•To check the P (Park) mechanism’s holding ability:
With the engine running, shift to P (Park). Thenrelease the parking brake followed by theregular brake.
Contact your dealer/retailer if service is required.

Engine Oil
The engine requires a specialengine oil meeting GM StandardGM4718M. Oils meeting thisstandard can be identified assynthetic, and should also beidentified with the AmericanPetroleum Institute (API) Certifiedfor Gasoline Engines starburstsymbol. However, not all syntheticAPI oils with the starburst symbolwill meet this GM standard. Look forand use only oil that meets GMStandard GM4718M. For the properviscosity, seeEngine Oil onpage 6-13.
