iv Preface

The vehicle can be started using the
remote start feature two separate
times between driving sequences.
The engine runs for 10 minutes after
each remote start. Or, the engine
run time can be extended another
10 minutes within the rst 10 minute
remote start time frame, and
before the engine stops.
For example, if
Qand then/are
pressed again after the vehicle
has been running for ve minutes,
10 minutes are added, allowing
the engine to run for 15 minutes.
The additional 10 minutes are
considered a second remote start.The vehicle must be started with the
key once two remote starts, or a
single remote start with one time
extension has been done.
The vehicle can be started using the
remote start feature again after
the key is removed from the ignition.
The vehicle cannot be started
using the remote start feature if the
key is in the ignition, the hood is
open, or if there is an emission
control system malfunction.
The engine turns off during a remote
start if the coolant temperature
gets too high or if the oil pressure
gets low.Vehicles that have the remote
vehicle start feature are shipped
from the factory with the remote
vehicle start system enabled. The
system may be enabled or disabled
through the DIC if the vehicle has
DIC buttons. See “REMOTE
START” underDIC Vehicle
Customization on page 3-57for
additional information. If the vehicle
does not have DIC buttons, see
your dealer/retailer to enable
or disable the remote start system.

2. If the engine does not start after
5-10 seconds, especially in
very cold weather (below 0°F
or−18°C), it could be ooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the oor and holding it there as
you hold the key in START for up
to a maximum of 15 seconds.
Wait at least 15 seconds between
each try, to allow the cranking
motor to cool down. When the
engine starts, let go of the key
and accelerator. If the vehicle
starts briey but then stops again,
repeat these steps. This clears
the extra gasoline from the
engine. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.Notice:The engine is designed
to work with the electronics
in the vehicle. If you add electrical
parts or accessories, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer/retailer. If you do not, the
engine might not perform
properly. Any resulting damage
would not be covered by the
vehicle warranty.
Engine Coolant Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below 0°F (−18°C). Vehicles
with an engine coolant heater should
be plugged in at least four hours
before starting. Some models
may have an internal thermostat
in the cord which will prevent engine
coolant heater operation at
temperatures above 0°F (−18°C).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The cord is
located on the driver side of the
engine compartment. It is
routed around the windshield
washer uid reservoir.
3. Plug the cord into a normal,
grounded 110-volt AC outlet.
{CAUTION
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a re. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet.
If the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.

Hydroplaning
Hydroplaning is dangerous. Water
can build up under your vehicle’s
tires so they actually ride on
the water. This can happen if the
road is wet enough and you
are going fast enough. When your
vehicle is hydroplaning, it has little or
no contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is
to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
Allow extra following distance.
Pass with caution.
Keep windshield wiping
equipment in good shape.
Keep the windshield washer uid
reservoir lled.
Have good tires with proper tread
depth. SeeTires on page 5-36.
Turn off cruise control.
Before Leaving on a
Long Trip
To prepare your vehicle for a long
trip, consider having it serviced
by your dealer/retailer before
departing.
Things to check on your own
include:
Windshield Washer Fluid:
Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All
levels checked?
Lamps:Do they all work and are
lenses clean?
Tires:Are treads good? Are tires
inated to recommended
pressure?
Weather and Maps:Safe to
travel? Have up-to-date maps?
Highway Hypnosis
Always be alert and pay attention
to your surroundings while driving.
If you become tired or sleepy, nd a
safe place to park your vehicle
and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan
the road ahead and to the sides.
Check the rearview mirror and
vehicle instruments often.
4-12 Driving Your Vehicle

Notice:Use only engine oil
identied as meeting GM
Standard GM6094M and showing
the American Petroleum
Institute Certied For Gasoline
Engines starburst symbol. Failure
to use the recommended oil
can result in engine damage not
covered by the vehicle warranty.
Cold Temperature Operation
If you are in an area of extreme
cold, where the temperature falls
below−20°F (−29°C), use either an
SAE 5W-30 synthetic oil or an
SAE 0W-30 engine oil. Both provide
easier cold starting for the engine at
extremely low temperatures. Always
use an oil that meets the required
specication, GM6094M. See “What
Kind of Engine Oil to Use” for more
information.
Engine Oil Additives / Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils with the starburst
symbol that meet GM Standard
GM6094M are all you need for good
performance and engine protection.
Engine oil system ushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that lets you know when to change
the engine oil and lter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change will
be indicated can vary considerably.
For the oil life system to work
properly, you must reset the system
every time the oil is changed.When the system has calculated
that oil life has been diminished, it
will indicate that an oil change
is necessary. A CHANGE ENGINE
OIL SOON message will come
on. Change the oil 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 oil life system might
not indicate that an oil change 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 people who will
perform this work using genuine
parts and reset the system. It is also
important to check the oil regularly
and keep it at the proper level.
If the system is ever reset
accidentally, you must change the
oil at 3,000 miles (5 000 km)
since the last oil change. Remember
to reset the oil life system whenever
the oil is changed.
Service and Appearance Care 5-13

Engine Coolant
The cooling system in the vehicle is
lled with DEX-COOL®engine
coolant. The 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, seeEngine
Overheating on page 5-20.
What to Use
{CAUTION
Adding only plain water to the
cooling system can be dangerous.
Plain water, or some other liquid
such as alcohol, can boil before
the proper coolant mixture will.
(Continued)
CAUTION (Continued)
The vehicle’s coolant warning
system is set for the proper
coolant mixture. With plain water
or the wrong mixture, the engine
could get too hot but you would
not get the overheat warning. The
engine could catch re and you or
others could be burned. Use a
50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant.
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant. If using this mixture, nothing
else needs to be added. This
mixture:
Gives freezing protection down to
−34°F (−37°C), outside
temperature.
Gives boiling protection up to
265°F (129°C), engine
temperature.
Protects against rust and
corrosion.
Will not damage aluminum parts.
Helps keep the proper engine
temperature.
Notice:If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much water in the mixture
can freeze and crack the engine,
radiator, heater core, and
other parts.
Notice:If extra inhibitors and/or
additives are used in the
vehicle’s cooling system, the
vehicle could be damaged. Use
only the proper mixture of
the engine coolant listed in this
manual for the cooling system.
SeeRecommended Fluids
and Lubricants on page 6-12for
more information.
Service and Appearance Care 5-17

If the temperature overheat gage is
no longer in the overheat zone or an
overheat warning no longer displays,
the vehicle can be driven. Continue
to drive the vehicle slow for about
10 minutes. Keep a safe vehicle
distance from the car in front of you.
If the warning does not come back
on, continue to drive normally.
If the warning continues, pull over,
stop, and park the vehicle right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see “Overheated
Engine Protection Operating
Mode” next in this section.Overheated Engine
Protection
Operating Mode
This emergency operating mode lets
the vehicle be driven to a safe place
in an emergency situation. If an
overheated engine condition exists,
an overheat protection mode which
alternates ring groups of cylinders
helps prevent engine damage. In this
mode, there is a signicant loss in
power and engine performance. The
temperature gage indicates an
overheat condition exists. Driving
extended distances and/or towing a
trailer in the overheat protection
mode should be avoided.Notice:After driving in the
overheated engine protection
operating mode, to avoid engine
damage, allow the engine to
cool before attempting any repair.
The engine oil will be severely
degraded. Repair the cause
of coolant loss, change the oil
and reset the oil life system. See
Engine Oil on page 5-11.
Power Steering Fluid
The power steering uid reservoir is
located toward the front of the engine
compartment on the passenger
side of the vehicle. SeeEngine
Compartment Overview on
page 5-10for reservoir location.
5-22 Service and Appearance Care

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. Remove engine oil ll cap.
3. Slide engine cover rearward and
lift to remove.
4. Wipe the cap and the top of the
reservoir clean.
5. Unscrew the cap and wipe the
dipstick with a clean rag.6. Replace the cap and completely
tighten it.
7. Remove the cap again and look
at the uid level on the dipstick.
The uid level should be somewhere
between MAX and MIN line on the
dipstick in room temperature. If the
uid is on or below MIN line, you
should add uid close to MAX Line.
What to Use
To determine what kind of uid to
use, seeRecommended Fluids and
Lubricants on page 6-12. 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 inRecommended Fluids
and Lubricants on page 6-12.
Windshield Washer Fluid
What to Use
When adding windshield washer
uid, be sure to read the
manufacturer’s instructions before
use. If the vehicle will be operating in
an area where the temperature may
fall below freezing, use a uid that
has sufficient protection against
freezing.
Service and Appearance Care 5-23

If you see anything that might keep
a safety belt system from doing
its job, have it repaired. Have any
torn or frayed safety belts replaced.
Also see Checking the Restraint
Systems on page 1-58.
(f)Lubricate all key lock cylinders,
hood latch assemblies, secondary
latches, pivots, spring anchor
and release pawl, hood and door
hinges, rear folding seats, and
liftgate hinges. 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)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.(h)Change automatic transmission
fluid 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 5-17 for
what to use. Inspect hoses. Clean
radiator, condenser, pressure cap,
and filler neck. Pressure test the
cooling system and pressure cap.
(j)Check system for interference or
binding and for damaged or missing
parts. Replace parts as needed.
