Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others could
be burned. Check your oil as soon as
possible and have your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.The light will come on
when you turn your
key to ON or START.
It goes off once you start your engine. That is
a check to be sure the light works. If it does not
come on, be sure to have it xed so it will be
there to warn you if something goes wrong.
When the light comes on and stays on, it means
that oil is not owing through the engine properly.
The vehicle could be low on oil and it might
have some other system problem. SeeEngine
Oil on page 333and “OIL” underDIC Warnings
and Messages on page 202for more information.

Always reset the OIL LIFE message after an
oil change. To reset the message, seeEngine
Oil Life System on page 336.
In addition to the engine oil life system monitoring
the oil life, additional maintenance is recommended
in the Maintenance Schedule in this manual.
SeeEngine Oil on page 333andScheduled
Maintenance on page 442for more information.

After Off-Road Driving
Remove any brush or debris that has collected
on the underbody, chassis, or under the hood.
These accumulations can be a re hazard.
After operation in mud or sand, have the brake
linings cleaned and checked. These substances
can cause glazing and uneven braking. Check
the body structure, steering, suspension,
wheels, tires, and exhaust system for damage.
Also, check the fuel lines and cooling system
for any leakage.
Your vehicle will require more frequent service
due to off-road use. Refer to the maintenance
schedule for additional information.
Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to
be impaired — by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce
the glare from headlamps behind you.
Since you cannot see as well, slow down
and keep more space between you and
other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only
so much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe
place and rest.

Maintenance When Trailer Towing
Your vehicle will need service more often
when you’re pulling a trailer. SeeScheduled
Maintenance on page 442for more on this.
Things that are especially important in trailer
operation are automatic transmission uid
(don’t overll), engine oil, axle lubricant, belt,
cooling system and brake system. Each of these
is covered in this manual, and the Index will
help you nd them quickly. If you’re trailering,
it’s a good idea to review these sections before
you start your trip.
Check periodically to see that all hitch nuts
and bolts are tight.
Trailer Wiring Harness
Your vehicle may be equipped with a four-pin
trailer towing harness. This harness has a four-pin
trailer connector that is attached to a bracket on
the hitch platform. The four-wire harness contains
the following trailer circuits:
Yellow: Left Stop/Turn Signal
Green: Right Stop/Turn Signal
Brown: Taillamps/Park lamps
White: Ground
Trailer Recommendations
You must subtract your hitch load from the CWR
for your vehicle. Weigh your vehicle with your trailer
attached, so that you won’t go over the GVWR or
the GAWR.
You’ll get the best performance if you spread
out the weight of your load the right way, and if
you choose the correct hitch and trailer brakes.
For more information, seeTowing a Trailer
on page 306later in this section.

Engine Air Cleaner/Filter
The engine air cleaner/lter is located in the
engine compartment on the passenger’s side of
the vehicle. SeeEngine Compartment Overview
on page 332for more information on location.
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change
after each 50,000 mile (83 000 km) interval.
SeeScheduled Maintenance on page 442for
more information. If you are driving in dusty/dirty
conditions, inspect the lter at each engine
oil change.
How to Inspect the Engine
Air Cleaner/Filter
To inspect or replace the engine air cleaner/lter,
do the following:
1. Unfasten the clips that hold the cover on
and remove the cover.
2. Lift out the engine air cleaner/lter.
3. Inspect or replace the air lter. SeeNormal
Maintenance Replacement Parts on page 454
to determine which lter to use.
4. Reinstall the engine air cleaner/lter cover.
Fasten the clips to hold the cover in place.

How to Add Automatic
Transmission Fluid
Refer to the Maintenance Schedule to determine
what kind of transmission uid to use. See
Recommended Fluids and Lubricants on page 452.
Add uid only after checking the transmission
uid while it is hot. A cold check is used only as a
reference. If the uid level is low, add only enough
of the proper uid to bring the level up to the HOT
area for a hot check. It does not take much uid,
generally less than one pint (0.5 L). Do not overll.
Notice:Use of the incorrect automatic
transmission uid may damage your vehicle,
and the damages may not be covered by
your warranty. Always use the automatic
transmission uid listed inRecommended
Fluids and Lubricants on page 452.
After adding uid, recheck the uid level as
described under “How to Check Automatic
Transmission Fluid,” earlier in this section.
When the correct uid level is obtained, push
the dipstick back in all the way; then ip the
handle down to lock the dipstick in place.
Manual Transmission Fluid
When to Check
A good time to have it checked is when the
engine oil is changed. However, the uid in your
manual transmission does not require changing.
How to Check
Because this operation can be a little difficult,
you may choose to have this done at your
GM dealer/retailer service department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading.
Notice:Too much or too little uid can
damage your transmission. Too little uid
could cause the transmission to overheat.
Be sure to get an accurate reading if you
check your transmission uid.
Check the uid level only when your engine is off,
the vehicle is parked on a level place and the
transmission is cool enough for you to rest your
ngers on the transmission case.
