How to Add Coolant to the Coolant
Surge Tank
If you have not found a problem yet, check to see
if coolant is visible in the surge tank. If coolant
is visible but the coolant level is not at or above
the FULL COLD mark, add a 50/50 mixture
of clean, drinkable water and DEX-COOL
®coolant
at the coolant surge tank, but be sure the
cooling system, including the coolant surge tank
pressure cap, is cool before you do it. SeeEngine
Coolant on page 415for more information.
If no coolant is visible in the surge tank, add
coolant as follows:
{CAUTION:
Steam and scalding liquids from a hot
cooling system can blow out and burn you
badly. They are under pressure, and if you
turn the radiator pressure cap — even a
little — they can come out at high speed.
CAUTION: (Continued)
CAUTION: (Continued)
Never turn the cap when the cooling
system, including the radiator pressure
cap, is hot. Wait for the cooling system
and radiator pressure cap to cool if you
ever have to turn the pressure cap.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.

Spare Tire
Your vehicle, when new, had a fully-inated spare
tire. A spare tire may lose air over time, so check its
ination pressure regularly. SeeInation - Tire
Pressure on page 456andLoading Your Vehicle on
page 362for information regarding proper tire
ination and loading your vehicle. For instruction on
how to remove, install or store a spare tire, see
Removing the Flat Tire and Installing the Spare Tire
on page 478andStoring a Flat or Spare Tire and
Tools (SUV) on page 485orStoring a Flat or Spare
Tire and Tools (SUT) on page 488.
After installing the spare tire on your vehicle, you
should stop as soon as possible and make
sure the spare is correctly inated. Have the
damaged or at road tire repaired or replaced as
soon as you can and installed back onto your
vehicle. This way, a spare tire will be available in
case you need it again.
Do not mix tires and wheels of different sizes,
because they will not t. Keep your spare tire and
its wheel together.
Appearance Care
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its
best if it is cleaned often. Although not always
visible, dust and dirt can accumulate on your
upholstery. Dirt can damage carpet, fabric, leather,
and plastic surfaces. Regular vacuuming is
recommended to remove particles from your
upholstery. It is important to keep your upholstery
from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible.
Your vehicle’s interior may experience extremes of
heat that could cause stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and
garments that transfer color to your home
furnishings may also transfer color to your
vehicle’s interior.

Maintenance Schedule
Introduction
Important: Keep engine oil at the proper level
and change as recommended.
Have you purchased the GM Protection Plan? The
Plan supplements your new vehicle warranties.
See your Warranty and Owner Assistance booklet
or your dealer for details.
Maintenance Requirements
Notice:Maintenance intervals, checks,
inspections, replacement parts, and
recommended uids and lubricants as
prescribed in this manual are necessary to
keep your vehicle in good working condition.
Any damage caused by failure to follow
scheduled maintenance may not be covered
by warranty.
514

If you want to purchase service information, see
Service Publications Ordering Information on
page 553.
Owner Checks and Services on page 523tells you
what should be checked, when to check it, and
what you can easily do to help keep your vehicle in
good condition.
The proper replacement parts, uids, and
lubricants to use are listed inRecommended
Fluids and Lubricants on page 528andNormal
Maintenance Replacement Parts on page 530.
When your vehicle is serviced, make sure these
are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of
genuine GM parts.Scheduled Maintenance
When the CHANGE ENGINE OIL message in the
Driver Information Center (DIC) comes on, it
means that service is required for your vehicle.
SeeDIC Warnings and Messages on page 226.
Have your vehicle serviced as soon as possible
within the next 600 miles (1 000 km). It is possible
that, if you are driving under the best conditions,
the engine oil life system may not indicate
that vehicle service is necessary for over a year.
However, your engine oil and lter must be
changed at least once a year and at this time the
system must be reset. Your GM Goodwrench
®
dealer has GM-trained service technicians who will
perform this work using genuine GM parts and
reset the system.
517

If the engine oil life system is ever reset
accidentally, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System on
page 407for information on the Engine Oil Life
System and resetting the system.
When the CHANGE ENGINE OIL message
appears, certain services, checks, and inspections
are required. Required services are described
in the following for “MaintenanceI” and
“MaintenanceII.” Generally, it is recommended
that your rst service be MaintenanceI, your
second service be MaintenanceII, and that you
alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases,
MaintenanceIImay be required more often.MaintenanceI— Use MaintenanceIif the
CHANGE ENGINE OIL message comes on within
10 months since the vehicle was purchased or
MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the
previous service performed was MaintenanceI.
Always use MaintenanceIIwhenever the message
comes on 10 months or more since the last
service or if the message has not come on at all
for one year.

At Each Fuel Fill
It is important to perform these underhood checks
at each fuel ll.
Engine Oil Level Check
Check the engine oil level and add the proper
oil if necessary. SeeEngine Oil on page 404for
further details.
Notice:It is important to check your oil
regularly and keep it at the proper level.
Failure to keep your engine oil at the proper
level can cause damage to your engine
not covered by your warranty.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. See
Engine Coolant on page 415for further details.
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
Visually inspect your vehicle’s tires and make
sure they are inated to the correct pressures.
Do not forget to check the spare tire. See
Ination - Tire Pressure on page 456. Check to
make sure the spare tire is stored securely.
SeeChanging a Flat Tire on page 468.
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. SeeTire
