Consistency of Readings
Always check the fluid level at leasttwice using the procedure describedpreviously. Consistency (repeatablereadings) is important to maintainingproper fluid level. If readings are stillinconsistent, contact the dealer.
Automatic Transmission
Fluid (8-Speed
Transmission)
When to Check and Change
Automatic Transmission Fluid
It is usually not necessary to checkthe transmission fluid level. The onlyreason for fluid loss is atransmission leak or overheatedtransmission. This vehicle is notequipped with a transmission fluidlevel dipstick. There is a specialprocedure for checking andchanging the transmission fluid inthese vehicles. Because thisprocedure is difficult, this should be
done at the dealer. Contact thedealer for additional information orthe procedure can be found in theservice manual. SeeServicePublications OrderingInformation0481.
Caution
Use of the incorrect automatic
transmission fluid may damage
the vehicle, and the damage may
not be covered by the vehicle
warranty. Always use the
automatic transmission fluid listed
inRecommended Fluids and
Lubricants0462.
Change the fluid and filter at thescheduled maintenance intervalslisted inMaintenance Schedule0452.Besuretousethetransmission fluid listed inRecommended Fluids andLubricants0462.
Manual Transmission
Fluid
It is not necessary to check themanual transmission fluid level.Atransmissionfluidleakistheonlyreason for fluid loss. If a leakoccurs, take the vehicle to yourdealer service department and haveit repaired as soon as possible. SeeRecommended Fluids andLubricants0462for the proper fluidto use.
Hydraulic Clutch
For vehicles with a manualtransmission, it is not necessary toregularly check clutch fluid unlessyou suspect there is a leak in thesystem. Adding fluid will not correctaleak.Afluidlossinthissystemcould indicate a problem. Have thesystem inspected and repaired.

When to Check and What
to Use
The hydraulic clutch fluid reservoiris filled with DOT 3 brake fluid asindicated on the reservoir cap. SeeEngine Compartment Overview0354for reservoir location.
How to Check and Add Fluid
Visually check the clutch fluidreservoir to make sure the fluid levelis at the MIN (minimum) line on theside of the reservoir. The hydraulicclutch fluid system should be closedand sealed.
Do not remove the cap to check thefluid level or to top-off the fluid level.Remove the cap only whennecessary to add the proper fluiduntil the level reaches the MIN line.
Engine Air Cleaner/Filter
If the vehicle has a diesel engine,see“8-Cylinder Pickup Models”under“Engine Air Cleaner/Filter”inthe Duramax diesel supplement forthe correct inspection andreplacement procedures.
The engine air cleaner/filter is onthe passenger side of the enginecompartment. SeeEngineCompartment Overview0354.
When to Inspect the Engine Air
Cleaner/Filter
For intervals on changing andinspecting the engine air filter, seeMaintenance Schedule0452.
How to Inspect the Engine Air
Cleaner/Filter
Do not start the engine or have theengine running with the engine aircleaner/filter housing open. Beforeremoving the engine air cleaner/filter, make sure that the engine aircleaner/filter housing and nearbycomponents are free of dirt anddebris. Remove the engine aircleaner/filter. Lightly tap and shakethe engine air cleaner/filter (awayfrom the vehicle), to release loosedust and dirt. Inspect the engine aircleaner/filter for damage, andreplace if damaged. Do not cleanthe engine air cleaner/filter orcomponents with water orcompressed air.
To i n s p e c t o r r e p l a c e t h e e n g i n e a i rcleaner/filter:
1. Screws
2. Electrical Connectors
3. Air Duct Clamp
1. Locate the air cleaner/filterassembly. SeeEngineCompartment Overview0354.
2. Disconnect the outlet duct byloosening the air ductclamp (3).
3. Disconnect the electricalconnectors (2) and theconnector harness from thecover.

Warning (Continued)
Add brake fluid only when work is
done on the brake hydraulic
system.
When the brake fluid falls to a lowlevel, the brake warning light comeson. SeeBrake System WarningLight0140.
Brake fluid absorbs water over time.Replace brake fluid at the specifiedintervals to prevent increasedstopping distance. SeeMaintenanceSchedule0452.
Checking Brake Fluid
Check brake fluid by looking at thebrake fluid reservoir. SeeEngineCompartment Overview0354.
The fluid level should be aboveMIN. If it is not, have the brakehydraulic system checked to see ifthere is a leak.
After work is done on the brakehydraulic system, make sure thelevel is above MIN but not over theMAX mark.
What to Add
Use only GM approved DOT 3brake fluid from a clean, sealedcontainer. SeeRecommendedFluids and Lubricants0462.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the
paint finish can be damaged.
Immediately wash off any painted
surface.
Battery - North America
The original equipment battery ismaintenance free. Do not removethe cap and do not add fluid.

.There is cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord or
fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation
Tires should be rotated every
12 000 km (7,500 mi). See
Maintenance Schedule0452.
Tires are rotated to achieve a
uniform wear for all tires. The
first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as soon
as possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel
alignment. SeeWhen It Is Time
for New Tires0414andWheel
Replacement0418.
Use this rotation pattern when
rotating the tires if the vehicle
has single rear wheels.
Dual Tire Rotation
When the vehicle is new,
or whenever a wheel, wheel
bolt, or wheel nut is replaced,
check the wheel nut torque after
160, 1 600, and 10 000 km (100,
1,000, and 6,000 mi) of driving.
For proper torque and wheel nut
tightening information, see
“Removing the Flat Tire and
Installing the Spare Tire”under
Tire Changing0422.
The outer tire on a dual wheel
setup generally wears faster
than the inner tire. Tires last
longer and wear more evenly if
they are rotated. SeeTire
Inspection0411andTire
Rotation0412.Alsosee
Maintenance Schedule0452.
{Warning
If the vehicle is operated with a
tire that is underinflated, the tire
can overheat. An overheated tire
