key battery CHEVROLET IMPALA 2007 9.G Owners Manual

Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
At times you may notice a decrease in range. This
is normal for any remote keyless entry system.
If the transmitter does not work or if you have to
stand closer to your vehicle for the transmitter
to work, try this:
Check the distance. You may be too far from
your vehicle. You may need to stand closer
during rainy or snowy weather.
Check the location. Other vehicles or objects
may be blocking the signal. Take a few steps
to the left or right, hold the transmitter
higher, and try again.
Check to determine if battery replacement or
resynchronization is necessary. See “Battery
Replacement” and “Resynchronization”
underRemote Keyless Entry (RKE) System
Operation on page 91.
If you are still having trouble, see your
dealer/retailer or a qualied technician
for service.
Remote Keyless Entry (RKE)
System Operation
The vehicle’s doors can be locked and unlocked,
and the trunk can be unlatched from about
3 feet (1 m) up to 65 feet (20 m) away with the
remote keyless entry transmitter.
If your vehicle has the remote start feature you
can also start your vehicle with the remote keyless
entry transmitter. Your remote keyless entry
transmitter, with the remote start button, provides
an increased range of 195 feet (60 m) away.
However, the range may be less while the vehicle
is running. As a result, you may need to be
closer to your vehicle to turn it off than you were
to turn it on.
There are other conditions which can affect the
performance of the transmitter. SeeRemote
Keyless Entry (RKE) System on page 90.

Battery Replacement
Under normal use, the battery in your remote
keyless entry transmitter should last about
four years.
You can tell 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
remote keyless entry transmitter battery is
low. See “REPLACE BATTERY IN REMOTE KEY”
underDIC Warnings and Messages on page 199
for 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 remote keyless entry
transmitter do the following:
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.
94

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.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine
from outside of the vehicle.
If your vehicle has an outside temperature display,
during remote start this feature allows the
climate control system to default to a heating
mode during colder outside temperatures and a
cooling mode during warmer outside temperatures.
If your vehicle does not have an outside
temperature display, during remote start the
climate control system will turn on at the setting
the vehicle was set to when the vehicle was
last turned off.Laws in some communities may restrict the use of
remote starters. For example, requiring a person
using remote start to have the vehicle in view
when doing so. Check local regulations for
any requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.
Your remote keyless entry transmitter, with
the remote start button, provides an increased
range of operation. However, the range may
be less while the vehicle is running. As a result,
you may need to be closer to your vehicle to turn it
off, than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry (RKE) System on page 90for
additional information.

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
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 (OFF):This is the only position in which the
ignition key can be inserted or removed. This
position locks the ignition and transaxle. It is a
theft-deterrent feature.
B (ACCESSORY):This position lets the radio and
windshield wipers operate while the engine is
off. To use ACCESSORY, turn the key clockwise.
C (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 ACCESSORY or 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
DOOR OPEN when the driver’s door is opened if
the ignition is in OFF, ACCESSORY and the
key is in the ignition. SeeDIC Warnings
and Messages on page 199for more information.

Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transaxle. Also, always remember
to lock the doors.
The battery could be drained if you leave the key
in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it
has been parked for an extended period of time.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine turned off:
Audio System
Power WindowsThe radio will work when the key is in RUN or
ACCESSORY. Once the key is turned from RUN to
OFF the radio will continue to work 10 minutes or
until the driver’s door is opened. The power
windows will continue to work for up to 10 minutes
or until any door is opened.
Starting the Engine
Place the transaxle in the proper gear.
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position -- this is a safety feature.
To restart when you are already moving, use
NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
113

Starting Procedure
1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as your engine gets warm. Do not race
the engine immediately after starting it.
Operate the engine and transaxle gently to
allow the oil to warm up and lubricate all
moving parts.
Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects components.
If the ignition key is turned to the START
position, and then released when the engine
begins cranking, the engine will continue
cranking for a few seconds or until the vehicle
starts. If the engine does not start and the key
is held in START for many seconds, cranking
will be stopped after 15 seconds to prevent
cranking motor damage. To prevent gear
damage, this system also prevents cranking if
the engine is already running. Engine cranking
can be stopped by turning the ignition switch to
the ACCESSORY or OFF position.Notice:Cranking the engine for long periods
of time, by returning the key to the START
position immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down.
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, do the same thing. This
clears the extra gasoline from the engine.
Do not race the engine immediately after
starting it. Operate the engine and transaxle
gently until the oil warms up and lubricates
all moving parts.

Delayed Exit Lighting
This feature illuminates the interior for a period of
time after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to
work. When the key is removed, interior illumination
will activate and remain on until one of the following
occurs:
The ignition is in ON.
The power door locks are activated.
An illumination period of 20 seconds has
elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled
and the interior lamps will remain on because a
door is open.
Parade Dimming
The instrument panel has an added feature called
parade mode. It automatically prohibits the
dimming of the instrument panel displays during
the daylight while the headlamps are on so
that you will still be able to see the displays.
Reading Lamps
The vehicle has reading lamps that also act as the
dome lamp. Press the button to turn them on
and off.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC), you
may see the voltage move up or down. This is
normal. If there is a problem, an alert will be
displayed.

Charging System Light
The charging system
light will come on briey
when you turn on
the ignition, but the
engine is not running,
as a check to show you
it is working.
It should go out once the engine is running.
If it stays on, or comes on while you are driving,
you may have a problem with the charging system.
It could indicate that you have problems with a
generator drive belt, or another electrical problem.
Have it checked right away. Driving while this
light is on could drain your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good braking,
though, you need both parts working well.
If the warning light comes on, there is a brake
problem. Have your brake system inspected
right away.
This light should come on briey when you turn
the ignition key to RUN. If it does not come
on then, have it xed so it will be ready to warn
you if there is a problem.
