2008 Chevrolet Impala Owner ManualM

Using this Manual
Many people read the owner manual from beginning to
end when they rst receive their new vehicle to learn
about the vehicle’s features and controls. Pictures
and words work together to explain things.
Index
A good place to quickly locate information about the
vehicle is the Index in the back of the manual. It is an
alphabetical list of what is in the manual and the
page number where it can be found.
Safety Warnings and Symbols
There are a number of safety cautions in this book.
A box with the word CAUTION is used to tell about
things that could hurt you or others if you were to ignore
the warning.
{CAUTION:
These mean there is something that could hurt
you or other people.
We tell you what the hazard is and what to do to help
avoid or reduce the hazard. Please read these cautions.
If you do not, you or others could be hurt.
A circle with a slash
through it is a safety
symbol which means
“Do Not,” “Do Not do
this” or “Do Not let this
happen.”
iii

Vehicle Damage Warnings
You will also nd notices in this manual.
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly.
The notice tells what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors or
in different words.
There are also warning labels on the vehicle which use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.

{CAUTION:
When an airbag inates, there may be dust in
the air. This dust could cause breathing
problems for people with a history of asthma or
other breathing trouble. To avoid this, everyone
in the vehicle should get out as soon as it is
safe to do so. If you have breathing problems
but cannot get out of the vehicle after an airbag
inates, then get fresh air by opening a window
or a door. If you experience breathing problems
following an airbag deployment, you should
seek medical attention.
Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on, and turn
the hazard warning ashers on when the airbags inate.
You can lock the doors, turn the interior lamps off,
and turn the hazard warning ashers off by using the
controls for those features.In many crashes severe enough to inate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger airbag.Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for
the airbag system. If you do not get them, the airbag
system will not be there to help protect you in
another crash. A new system will include airbag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
Your vehicle has a crash sensing and diagnostic
module which records information after a crash.
SeeVehicle Data Recording and Privacy on
page 7-16andEvent Data Recorders on page 7-17.
Let only qualied technicians work on the airbag
systems. Improper service can mean that an
airbag system will not work properly. See your
dealer/retailer for service.
1-61

Battery Replacement
Under normal use, the battery in your RKE transmitter
should last about four years.
The battery is weak if the transmitter will not work at the
normal range in any location. If you have to get close
to your vehicle before the transmitter works, it is
probably time to change the battery.
The REPLACE BATTERY IN REMOTE KEY message
in the vehicle’s DIC will display if the RKE transmitter
battery is low. See “REPLACE BATTERY IN REMOTE
KEY” underDIC Warnings and Messages on
page 3-52for additional information.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.To replace the battery in the RKE transmitter:
1. Use a at object with a thin edge into the notch,
located below the trunk release button, and separate
the bottom half from the top half of the transmitter.
2. Remove the old battery, but do not use a metal
object to do this.
3. Slide the new battery into the transmitter with the
positive side of the battery facing down. Use a
type CR2032 battery, or equivalent type. Make sure
the cover is on tightly, so water will not get in.
4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.
2-7

The engine will shut off automatically after 10 minutes,
unless a time extension has been done or the
vehicle’s key is inserted into the ignition switch and
turned to ON/RUN.
To manually shut off a remote start, do any of the
following.
Aim the RKE transmitter at the vehicle and press
and release the remote start button.
Turn on the hazard warning ashers.
Turn the ignition switch out of LOCK/OFF position
and then back to LOCK/OFF.
After the engine has been started two times, or one
time with a time extension, the vehicle’s ignition must be
turned to ON/RUN using the key before the remote
start procedure can be used again. SeeIgnition
Positions on page 2-22for information regarding the
ignition positions on your vehicle.
The remote vehicle start feature will not operate if any
of the follow occur:
The remote start system is disabled through the DIC.
The vehicle’s key is in the ignition.
The vehicle’s hood is open.
The hazard warning ashers are on.
The check engine light is on. SeeMalfunction
Indicator Lamp on page 3-39.
The engine coolant temperature is too high.
The oil pressure is low.
Two remote vehicle starts, or one start with a time
extension, have already been provided for that
ignition cycle.
Remote Start Ready
If your vehicle does not have the remote vehicle start
feature, it may have the remote start ready feature.
This feature allows your dealer/retailer to add the
manufacturer’s remote vehicle start feature.
If your vehicle has the remote start ready feature, your
RKE transmitter will have extended range that will
allow you to lock or unlock your vehicle from about
195 feet (60 m) away.
See your dealer/retailer if you would like to add the
manufacturer’s remote vehicle start feature to your
vehicle.
2-9

Ignition Positions
With the ignition key in the
ignition, the key can be
turned to four different
positions.
In order to shift out of PARK (P), the ignition must be in
ON/RUN and the regular brake pedal must be applied.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way.
If none of this works, then your vehicle needs
service.A (LOCK/OFF):This is the only position in which the
ignition key can be inserted or removed. This position
locks the ignition and transmission. It is a theft-deterrent
feature.
If the steering wheel is locked, move it from right to left
and turn the key to ACC/ACCESSORY. If none of
this works, then your vehicle needs service.
B (ACC/ACCESSORY):This position lets the radio
and windshield wipers operate while the engine is off.
To use ACC/ACCESSORY, turn the key clockwise.
C (ON/RUN):This position is where the key returns to
after the vehicle is started. This position displays
some of the warning and indicator lights.
The battery could be drained if you leave the key in
the ACC/ACCESSORY or ON/RUN position with the
engine off. You may not be able to start your vehicle if the
battery is allowed to drain for an extended period of time.
D (START):This position starts the engine.
A warning chime will sound and the Driver Information
Center (DIC) will display DRIVER’S DOOR AJAR
