Checking Things Under
the Hood
{WARNING:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing, and tools away from any
underhood electric fan.
{WARNING:
Things that burn can get on hot engine parts and
start a fire. These include liquids like fuel, oil,
coolant, brake fluid, windshield washer and other
fluids, and plastic or rubber. You or others could
be burned. Be careful not to drop or spill things
that will burn onto a hot engine.

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.

Checking Coolant
The vehicle must be on a level surface when checkingthe coolant level.
Check to see if coolant is visible in the coolant surgetank. If the coolant inside the coolant surge tank isboiling, do not do anything else until it cools down.If coolant is visible but the coolant level is not at orabove the FULL COLD mark, add a 50/50 mixture ofclean, drinkable water and DEX-COOL®coolant at thecoolant surge tank, but be sure the cooling system iscool before this is done.
The coolant surge tank is located in the enginecompartment on the passenger side of the vehicle.SeeEngine Compartment Overviewon page 7!16formore information on location.
The coolant level should be at or above the FULLCOLD mark. If it is not, you may have a leak in thecooling system.

Checking Brake Fluid
Check brake fluid by looking at the brake fluid reservoir.SeeEngine Compartment Overview on page 7!16.
The fluid level should beabove MIN. If it is not,have the brake hydraulicsystem checked to see ifthere is a leak.
After work is done on the brake hydraulic system, makesure the level is above the MIN but not over theMAX mark.
What to Add
Use only new DOT 3 brake fluid from a sealedcontainer. SeeRecommended Fluids and Lubricantsonpage 8!10.
Always clean the brake fluid reservoir cap and the areaaround the cap before removing it. This helps keep dirtfrom entering the reservoir.
{WARNING:
With the wrong kind of fluid in the brake hydraulic
system, the brakes might not work well. This could
cause a crash. Always use the proper brake fluid.
Notice:
.Using the wrong fluid can badly damage
brake hydraulic system parts. For example,
just a few drops of mineral-based oil, such
as engine oil, in the brake hydraulic system
can damage brake hydraulic system parts so
badly that they will have to be replaced. Do
not let someone put in the wrong kind of
fluid.
.If brake fluid is spilled on the vehicle's
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on the vehicle. If you do, wash it off
immediately. SeeWashing Your Vehicleon
page 7!102.

Every Engine Oil Change
.Change engine oil and filter. SeeEngine Oilonpage 7!17.An Emission Control Service.
.Engine coolant level check. SeeEngine Coolanton page 7!29.
.Windshield washer fluid level check. SeeWindshield Washer Fluid on page 7!39.
.Tire inflation check. SeeInflation - Tire Pressureon page 7!65.
.Tire wear inspection. SeeTire Inspection andRotation on page 7!71.
.Rotate tires. SeeTire Inspection and Rotationonpage 7!71.
.Fluids visual leak check (or every 12 months,whichever occurs first). A leak in any system mustbe repaired and the fluid level checked.
.Engine air cleaner filter inspection. SeeEngine AirCleaner/Filter on page 7!22.
.Brake system inspection (or every 12 months,whichever occurs first).
.Lubricate the front suspension, steering linkage,and parking brake cable guides. Control arm balljoints are maintenance!free.
.Steering and suspension inspection. Visualinspection for damaged, loose, or missing parts orsigns of wear.
.Engine cooling system inspection. Visualinspection of hoses, pipes, fittings, and clamps andreplacement, if needed.
.Windshield wiper blade inspection for wear,cracking, or contamination and windshield andwiper blade cleaning, if contaminated. SeeWindshield, Backglass, and Wiper Bladesonpage 7!104. Worn or damaged wiper bladereplacement. SeeWindshield Wiper BladeReplacement on page 7!57.
.Body hinges and latches, key lock cylinders, rearcompartment hinges, outer tailgate handle pivotpoints, and folding seat hardware lubrication. SeeRecommended Fluids and Lubricantsonpage 8!10. More frequent lubrication may berequired when vehicle is exposed to a corrosiveenvironment. Applying silicone grease onweatherstrips with a clean cloth makes them lastlonger, seal better, and not stick or squeak.
.Restraint system component check. SeeCheckingthe Restraint Systems on page 2!91.
.Automatic transmission fluid level check andadding fluid, if needed. SeeAutomaticTransmission Fluid on page 7!24.
