2008 Pontiac G5 Owner ManualM

Heated Seats
Your vehicle may have heated front seats. The switches
are located on the instrument panel above the climate
control system.
Press the side of the
switch with the double
indicator lights to turn on
the heated seat at the
highest setting.
Both indicator lights will be lit to indicate that the setting
is on high. Press the side of the switch with the single
indicator light to go to the low setting. The indicator light
will be lit to indicate that the setting is on low. Return
the switch to the center to turn off the heated seat.
If your vehicle has been turned off, the last heated
seat setting will be retained when the vehicle is
started again.
Reclining Seatbacks
{CAUTION:
You can lose control of the vehicle if you try to
adjust a manual driver’s seat while the vehicle
is moving. The sudden movement could startle
and confuse you, or make you push a pedal
when you do not want to. Adjust the driver’s
seat only when the vehicle is not moving.
{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
push and pull on the seatback to be sure it is
locked. Driver’s Switch Shown,

Battery Replacement
Replace the battery if the KEY FOB BATT LOW
message displays in the DIC. See “KEY FOB BATT
LOW” underDIC Warnings and Messages on page 3-44
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. Separate the halves of the transmitter with a at,
thin object inserted into the notch on the side.
2. Remove the old battery. Do not use a metal object.3. Insert the new battery, positive side facing up.
Replace with a CR2032 or equivalent battery.
4. Put the transmitter back together tightly.
Remote Vehicle Start
Your vehicle may have a remote start feature. This
feature allows you to start the engine from outside the
vehicle. It may also start the vehicle’s heating or air
conditioning systems. When you start your vehicle using
the remote start feature, the climate control system
will come on and adjust the interior to the temperature
settings that you left it set to when you turned the
vehicle off.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require 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.
The remote start feature provides two separate starts
per ignition cycle, each with 10 minutes of engine
running time.
2-6

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, if the vehicle has one, the power
door lock switch, or by lifting the rear door
manual lock.
2. Open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert the key into the security lock slot and turn it
so the slot is in the vertical position.
Lockout Protection
If your vehicle has power door locks, it will have this
feature. If you press the power door lock switch
when the key is in the ignition and any door is open, all
the doors will lock and the driver’s door will unlock.
Be sure to remove the key from the ignition when locking
your vehicle.
The lockout protection can be overridden by pressing
and holding the power door lock in the lock position for
three seconds.
Trunk
To release the trunk lid from the outside, use the key or
the remote keyless entry transmitter, if equipped.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-36.
2-12

Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-36.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-20.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. Do not leave your vehicle when the engine
is running unless you have to. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set the
parking brake and move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into PARK (P) (Automatic
Transmission) on page 2-33.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer (Manual Transmission)
on page 4-32orTowing a Trailer (Automatic
Transmission) on page 4-32.

Entry/Exit Lighting
The lamps inside the vehicle will go on when any door
is opened. These lamps fade out about 20 seconds
after all of the doors have been closed or when
the ignition is turned to ON/RUN. These lamps will also
go on when pressing the trunk release, unlock symbol,
or the horn symbol button on the Remote Keyless Entry
System (RKE) Transmitter.
After the key is removed from the ignition, the lamps
inside the vehicle stay on for about 20 seconds to
provide an illuminated exit.
Mirror Reading Lamps
Your vehicle may have reading lamps on the rearview
mirror. Push the button to turn the reading lamps on
and off.
Electric Power Management
This vehicle has Electric Power Management (EPM),
an advanced control system. It estimates the battery’s
temperature and state of charge and 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.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be
spinning fast enough at idle to produce all the power
that is needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at high
speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands of
some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels
of corrective action, this action may be noticeable to
the driver.
