When the CHANGE ENGINE OIL SOON message
appears, the following services, checks, and inspections
are required:
❑ Change engine oil and lter. See Engine Oil on
page 6-15 . Reset oil life system. See Engine
Oil Life System on page 6-18 . An Emission
Control Service.
❑ Lubricate chassis components. See footnote #.
❑ Visually check for any leaks or damage.
See footnote (j).
❑ Inspect engine air cleaner lter or change indicator
(if equipped). If necessary, replace lter. See Engine
Air Cleaner/Filter on page 6-19 . See footnote (k).

See Tire Inspection and Rotation on page 6-69 and
“Tire Wear Inspection” in At Least Once a Month on
page 7-10 . ❑ Inspect brake system. See footnote (a).
❑ Check engine coolant and windshield washer uid
levels and add uid as needed.

(f) Lubricate all key lock cylinders, hood latch assembly,
secondary latch, pivots, spring anchor, release pawl, rear
compartment hinges, outer tailgate handle pivot points,
latch bolt, fuel door hinge, and folding seat hardware.
More frequent lubrication may be required when exposed
to a corrosive environment. Applying silicone grease on
weatherstrips with a clean cloth will make them last
longer, seal better, and not stick or squeak.
(g) Inspect system. Check all fuel and vapor lines
and hoses for proper hook-up, routing, and condition.
Check that the purge valve works properly, if equipped.
Replace as needed.
(h) Change automatic transmission fluid and filter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.
(i) Drain, flush, and refill cooling system. This service
can be complex; you should have your dealer/retailer
perform this service. See Engine Coolant on page 6-25
for what to use. Inspect hoses. Clean radiator,
condenser, pressure cap, and filler neck. Pressure
test the cooling system and pressure cap. (j) A fluid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired and
the fluid level checked. Add fluid if needed.
(k) If driving regularly under dusty conditions, inspect
the filter at each engine oil change.
(l) Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.
(m) Check vent hose at transfer case for kinks and
proper installation. Check to be sure vent hose is
unobstructed, clear, and free of debris. During any
maintenance, if a power washer is used to clean mud
and dirt from the underbody, care should be taken to
not directly spray the transfer case output seals.
High pressure water can overcome the seals and
contaminate the transfer case fluid. Contaminated fluid
will decrease the life of the transfer case and should
be replaced.
(n) Severe Service: Change transfer case fluid if the
vehicle is mainly used for trailer towing or driven in city
traffic, wet environment, or high ambient temperatures.

Owner Checks and Services These owner checks and services should be performed
at the intervals specied to help ensure vehicle
safety, dependability, and emission control performance.
Your dealer/retailer can assist with these checks and
services.
Be sure any necessary repairs are completed at once.
Whenever any uids or lubricants are added to the
vehicle, make sure they are the proper ones, as shown
in Recommended Fluids and Lubricants on page 7-13 .
At Each Fuel Fill It is important to perform these underhood checks at
each fuel fill.
Engine Oil Level Check Notice: It is important to check the engine oil
regularly and keep it at the proper level. Failure to
keep the engine oil at the proper level can cause
damage to the engine not covered by the vehicle
warranty.
Check the engine oil level and add the proper oil if
necessary. See Engine Oil on page 6-15 . Engine Coolant Level Check Check the engine coolant level and add DEX-COOL ®
coolant mixture if necessary. See Engine Coolant
on page 6-25 .
Windshield Washer Fluid Level Check Check the windshield washer uid level in the
windshield washer uid reservoir and add the proper
uid if necessary.
At Least Once a Month
Tire Ination Check Inspect the vehicle’s tires and make sure they are
inated to the correct pressures. Do not forget to check
the spare tire, if the vehicle has one. See Inflation - Tire
Pressure on page 6-62 . If the vehicle has a spare tire,
check to make sure it is stored securely. See Changing
a Flat Tire on page 6-78 .
Tire Wear Inspection Tire rotation may be required for high mileage highway
drivers prior to the Engine Oil Life System service
notication. Check the tires for wear and, if necessary,
rotate the tires. See Tire Inspection and Rotation on
page 6-69 .

At Least Once a Year Starter Switch Check
{ CAUTION: When you are doing this inspection, the vehicle
could move suddenly. If the vehicle moves, you or
others could be injured.

room around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. See Parking Brake on page 2-34 .
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. Try to start the engine in each gear. The vehicle
should start only in P (Park) or N (Neutral). If the
vehicle starts in any other position, contact your
dealer/retailer for service. Automatic Transmission Shift Lock
Control System Check
{ CAUTION: When you are doing this inspection, the vehicle
could move suddenly. If the vehicle moves, you or
others could be injured.

Ignition Transmission Lock Check While parked, and with the parking brake set, try to turn
the ignition to LOCK/OFF in each shift lever position.
The ignition should turn to LOCK/OFF only
when the shift lever is in P (Park).
The ignition key should come out only in
LOCK/OFF.
Contact your dealer/retailer if service is required.
Parking Brake and Automatic
Transmission P (Park) Mechanism
Check
{ CAUTION: 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 facing
downhill. Keeping your foot on the regular brake,
set the parking brake.
To check the parking brake’s holding ability: With
the engine running and transmission in N (Neutral),
slowly remove foot pressure from the regular brake
pedal. Do this until the vehicle is held by the parking
brake only.
To check the P (Park) mechanism’s holding
ability: With the engine running, shift to P (Park).
Then release the parking brake followed by the
regular brake.
Contact your dealer/retailer if service is required.
Hood and Liftgate Support Gas Strut
Service Visually inspect gas strut for signs of wear, corrosion,
cracks, loss of lubricant, or other damage. Check
the hold open ability of gas strut. If necessary,
replace with genuine parts from your dealer/retailer.
Underbody Flushing Service At least every spring, use plain water to ush any
corrosive materials from the underbody. Take care to
clean thoroughly any areas where mud and other debris
can collect.

Note to Canadian Customers: All listed prices are
quoted in U.S. funds. Canadian residents are to make
checks payable in U.S. funds. Vehicle Data Recording and
Privacy Your GM vehicle has a number of sophisticated
computers that record information about the vehicle’s
performance and how it is driven. For example, your
vehicle uses computer modules to monitor and control
engine and transmission performance, to monitor the
conditions for airbag deployment and deploy airbags in a
crash and, if so equipped, to provide antilock braking to
help the driver control the vehicle. These modules may
store data to help your dealer/retailer technician service
your vehicle. Some modules may also store data about
how you operate the vehicle, such as rate of fuel
consumption or average speed. These modules may also
retain the owner’s personal preferences, such as radio
pre-sets, seat positions, and temperature settings.
