{ CAUTION: An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
{ CAUTION: Heater and radiator hoses, and other engine parts,
can be very hot. Do not touch them. If you do, you
can be burned.
Do not run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine re, and you could be burned.
Get any leak xed before you drive the vehicle. Notice: Using coolant other than DEX-COOL ®
can
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant could
require changing sooner, at 50 000 km (30,000 miles)
or 24 months, whichever occurs rst. Any repairs
would not be covered by the vehicle warranty.
Always use DEX-COOL ®
(silicate-free) coolant in the
vehicle.
Engine Coolant The cooling system in the vehicle is lled with
DEX-COOL ®
engine coolant. This coolant is designed
to remain in the vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst.
The following explains the cooling system and how to
check and add coolant when it is low. If there is a
problem with engine overheating, see Engine
Overheating on page 6-30 .
6-25

Checking Coolant The vehicle must be on a level surface when checking
the coolant level.
Check to see if coolant is visible in the coolant surge
tank. If the coolant inside the coolant surge tank is
boiling, do not do anything else until it cools down.
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 is
cool before this is done.
The coolant surge tank is located in the engine
compartment on the passenger side of the vehicle.
See Engine Compartment Overview on page 6-14 for
more information on location.
The coolant level should be at or above the FULL
COLD mark. If it is not, you may have a leak in the
cooling system.
6-27

You may decide not to lift the hood when this warning
appears, but instead get service help right away.
See Roadside Service on page 8-7 .
If you do decide to lift the hood, make sure the vehicle
is parked on a level surface.
Then check to see if the engine cooling fans are
running. If the engine is overheating, both fans should
be running. If they are not, do not continue to run
the engine and have the vehicle serviced.
Notice: Engine damage from running your engine
without coolant is not covered by your warranty.
See Overheated Engine Protection Operating Mode
on page 6-33 for information on driving to a safe
place in an emergency.
Notice: If the engine catches re while driving with
no coolant, the vehicle can be badly damaged.
The costly repairs would not be covered by
the vehicle warranty. See Overheated Engine
Protection Operating Mode on page 6-33 for
information on driving to a safe place in an
emergency. If Steam Is Coming From The Engine
Compartment
{ CAUTION: Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Turn it off and get everyone away from the
vehicle until it cools down. Wait until there is no sign
of steam or coolant before you open the hood.
If you keep driving when the vehicles engine is
overheated, the liquids in it can catch re. You or
others could be badly burned. Stop the engine if it
overheats, and get out of the vehicle until the
engine is cool.
See Overheated Engine Protection Operating Mode
on page 6-33 for information on driving to a safe
place in an emergency.

When to Check Power Steering Fluid It is not necessary to regularly check power steering uid
unless you suspect there is a leak in the system or
you hear an unusual noise. A uid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid To check the power steering uid:
1. Turn the key off and let the engine compartment
cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the uid level on
the dipstick.
The level should be at the FULL COLD mark.
If necessary, add only enough uid to bring the
level up to the mark. What to Use To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 7-13 .
Always use the proper uid.
Notice: Use of the incorrect uid may damage the
vehicle and the damages may not be covered by
the vehicle’s warranty. Always use the correct uid
listed in Recommended Fluids and Lubricants
on page 7-13 .
Windshield Washer Fluid
What to Use When windshield washer uid needs to be added, be
sure to read the manufacturer’s instructions before use.
Use a uid that has sufficient protection against
freezing in an area where the temperature may fall
below freezing.
6-34

{ CAUTION: If too much brake uid is added, it can spill on
the engine and burn, if the engine is hot enough.
You or others could be burned, and the vehicle
could be damaged. Add brake uid only when
work is done on the brake hydraulic system.
See “Checking Brake Fluid” in this section.
When the brake uid falls to a low level, the brake
warning light comes on. See Brake System Warning
Light on page 3-39 .
Refer to the Maintenance Schedule to determine when
to check the brake uid. See Scheduled Maintenance
on page 7-4 . Checking Brake Fluid Check brake uid by looking at the brake uid reservoir.
See Engine Compartment Overview on page 6-14 .
The uid level should be
above MIN. If it is not,
have the brake hydraulic
system checked to
see if there is a leak.
After work is done on the brake hydraulic system,
make sure the level is above the MIN but not over the
MAX mark.
6-37

CAUTION: (Continued) Battery uid contains acid that can burn you.
Do not get it on you. If you accidentally get it in
your eyes or on your skin, ush the place with
water and get medical help immediately.
{ CAUTION: Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
5. Check that the jumper cables do not have loose or
missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if
the vehicle has one. Negative ( − ) will go to a heavy,
unpainted metal engine part or to a remote
negative ( − ) terminal if the vehicle has one. Do not connect positive (+) to negative ( − )oryou
will get a short that would damage the battery
and maybe other parts too. And do not connect the
negative ( − ) cable to the negative ( − ) terminal on
the dead battery because this can cause sparks.
6. Connect the red
positive (+) cable to the
positive (+) terminal
of the vehicle with the
dead battery. Use
a remote positive (+)
terminal if the
vehicle has one.
7. Do not let the other end touch metal. Connect it to
the positive (+) terminal of the good battery. Use a
remote positive (+) terminal if the vehicle has one.

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 the vehicle warranties. See the Warranty
and Owner Assistance booklet or your dealer/retailer
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 this vehicle in good working condition.
Any damage caused by failure to follow scheduled
maintenance might not be covered by the vehicle
warranty.
Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep
the vehicle in good working condition, but also helps
the environment. All recommended maintenance is
important. Improper vehicle maintenance can even affect
the quality of the air we breathe. Improper uid levels or
the wrong tire ination can increase the level of emissions
from the vehicle. To help protect the environment, and to
keep the vehicle in good condition, be sure to maintain
the vehicle properly.
7-2

Owner Checks and Services on page 7-10 tells what
should be checked, when to check it, and what can easily
be done to help keep the vehicle in good condition.
The proper replacement parts, uids, and lubricants to
use are listed in Recommended Fluids and Lubricants
on page 7-13 and Maintenance Replacement Parts on
page 7-15 . When the 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
parts from your dealer/retailer.
Scheduled Maintenance To maintain the ride, handling, and performance of this
vehicle, it is important that the rst tire rotation service
be performed when the vehicle has 5,000 to 8,000 miles
(8 000 to 13 000 km). Check tires for ination pressures
and wear. See Tires on page 6-56 . Rotate tires. See Tire
Inspection and Rotation on page 6-69 and “Tire Wear
Inspection” in At Least Once a Month on page 7-10 . When the CHANGE ENGINE OIL SOON message
displays, service is required for the vehicle. Have the
vehicle serviced as soon as possible within the next
600 miles (1 000 km). It is possible that, if driving under
the best conditions, the engine oil life system may not
indicate that vehicle service is necessary for over a year.
However, the engine oil and lter must be changed at
least once a year and at this time the system must be
reset. Your dealer/retailer has trained service technicians
who will perform this work using genuine parts and reset
the system.
If the engine oil life system is ever reset accidentally,
service your vehicle within 3,000 miles (5 000 km) since
the last service. Remember to reset the oil life system
whenever the oil is changed. See Engine Oil Life System
on page 6-18 for information on the Engine Oil Life
System and resetting the system.
