Ignition Positions
The ignition switch has
four different positions.
{CAUTION:
On manual transmission vehicles, turning the key
to LOCK/OFF will lock the steering column and
result in a loss of ability to steer the vehicle.
This could cause a collision. If you need to turn
the engine off while the vehicle is moving, turn the
key only to ACC/ACCESSORY. Do not push the
key in while the vehicle is moving.Notice:Using a tool to force the key to turn in the
ignition could cause damage to the switch or break
the key. Use the correct key, make sure it is all the
way in, and turn it only with your hand. If the key
cannot be turned by hand, see your dealer/retailer.
LOCK/OFF:This position locks the steering wheel,
ignition, shift lever and transmission. This is the
only position in which you can insert or remove the key.
The steering can bind with the wheels turned off
center. If this happens, move the steering wheel from
right to left while turning the key to ACC/ACCESSORY.
If this doesn’t work, then the vehicle needs service.
ACC/ACCESSORY:This position operates some of the
electrical accessories, such as the radio, but not the
climate control system.
ON/RUN:This position can be used to operate the
electrical accessories, and to display some instrument
panel cluster warning and indicator lights. The switch
stays in this position when the engine is running. If you
leave the key in the ACC/ACCESSORY or ON/RUN
position with the engine off, the battery could be drained.
You may not be able to start the vehicle if the battery
is allowed to drain for an extended period of time.
START:This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving. Do not turn
the key to START if the engine is running.

D4 (Automatic Overdrive):This position is for normal
driving.
When operating the vehicle in severe cold conditions,
the transmission may be prevented from shifting into
D4 gear until the transmission uid has warmed up to
it’s operational temperature.
Notice:If the vehicle seems to start up rather
slowly or not shift gears when you go faster, and
you continue to drive the vehicle that way, you could
damage the transmission. Have the vehicle serviced
right away. You can drive in 2 (Second) when you are
driving less than 35 mph (55 km/h) and D4 (Automatic
Overdrive) for higher speeds until then.
2 (Second):This position gives you more power but
lower fuel economy. You can use 2 (Second) on hills.
It can help control vehicle speed as you go down steep
mountain roads, while using the brakes off and on.
Notice:Do not drive in 2 (Second) at speeds
over 65 mph (105 km/h), or you can damage the
transmission. Use D4 (Automatic Overdrive) as
much as possible. Do not shift into 2 (Second) unless
you are going slower than 65 mph (105 km/h) or you
can damage the engine.1 (First):This position gives you even more power but
lower fuel economy than 2 (Second). You can use it
on very steep hills, or in deep snow or mud. If the shift
lever is put in 1 (First), the transmission will not shift
into rst gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator pedal
may damage the transmission. The repair will not be
covered by the vehicle warranty. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.
If there is a malfunction with the automatic transmission,
the malfunction indicator lamp (MIL) or the HOLD
indicator light will turn on or ash. SeeMalfunction
Indicator Lamp on page 3-32orHold Mode Light on
page 3-30.
Have the vehicle xed as soon as possible.

How OnStar Service Works
The OnStar system can record and transmit vehicle
information. This information is automatically sent to an
OnStar Call Center when the OnStar button is pressed,
the emergency button is pressed, or if the airbags or
AACN system deploy. This information usually includes
the vehicle’s GPS location and, in the event of a crash,
additional information regarding the crash that the vehicle
was involved in (e.g. the direction from which the vehicle
was hit). When the Virtual Advisor feature of OnStar
Hands-Free Calling is used, the vehicle also sends
OnStar the vehicle’s GPS location so they can provide
services where it is located.
OnStar service cannot work unless the vehicle is in a
place where OnStar has an agreement with a wireless
service provider for service in that area. OnStar service
also cannot work unless the vehicle is in a place where
the wireless service provider OnStar has hired for that
area has coverage, network capacity and reception when
the service is needed, and technology that is compatible
with the OnStar service. Not all services are available
everywhere, particularly in remote or enclosed areas,
or at all times.Location information about the vehicle is only available
if the GPS satellite signals are unobstructed and
available.
The vehicle must have a working electrical system,
including adequate battery power, for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service at any particular time or place. Some
examples are damage to important parts of the vehicle in
a crash, hills, tall buildings, tunnels, weather or wireless
phone network congestion.
Your Responsibility
Increase the volume of the radio if the OnStar advisor
cannot be heard. If the light next to the OnStar buttons is
red, the system may not be functioning properly. Press
the OnStar button and request a vehicle diagnostic. If the
light appears clear (no light is appearing), your OnStar
subscription has expired and all services have been
deactivated. Press the OnStar button to conrm that
the OnStar equipment is active.

Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started
this light and chime
comes on and stays on
for several seconds to
remind the people to
fasten their safety belts.
The light also begins
to ash.
This cycle repeats if the driver remains unbuckled and
the vehicle is moving.
If the driver safety belt is already buckled, neither the
light nor chime comes on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, which shows the airbag symbol.
The system checks the airbag’s electrical system for
malfunctions. The light tells if there is an electrical
problem. The system check includes the airbag sensor,
the airbag modules, the wiring and the crash sensing
and diagnostic module. For more information on
the airbag system, seeAirbag System on page 1-58.This light comes on when
the vehicle is started,
and it will ash for a
few seconds. When the
light goes out this indicates
the system is functioning
properly.
If the airbag readiness light stays on or comes on while
driving, the airbag system may not work properly.
Have the vehicle serviced right away.
{CAUTION:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inate in a crash, or they could even inate
without a crash. To help avoid injury, have the
vehicle serviced right away.

Passenger Airbag Status Indicator
The vehicle has the passenger sensing system.
SeePassenger Sensing System on page 1-65for
important safety information. The vehicle has a
passenger airbag status indicator in the clock,
located in the center of the instrument panel.
When the vehicle is started, the passenger airbag status
indicator will light ON and OFF or the symbol for on and
off, for several seconds as a system check. Then, after
several more seconds, the status indicator will light
either ON or OFF, or either the on or off symbol, to let you
know the status of the right front passenger frontal and
seat-mounted side impact airbag (if equipped).If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger frontal airbag and seat-mounted side impact
airbag (if equipped) are enabled (may inate).
If the word OFF or the off symbol is lit on the passenger
airbag status indicator, it means that the passenger
sensing system has turned off the right front passenger
frontal airbag and seat-mounted side impact airbag
(if equipped).
If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be
a problem with the lights or the passenger sensing
system. See your dealer/retailer for service.
{CAUTION:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light on page 3-26
for more information, including important safety
information. United States

{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.This light should come on briey when the ignition is
turned to ON. If it does not come on then, have it xed
so it will be ready to warn if there is a problem.
When the ignition is on, the brake system warning light
will also come on when the parking brake is set.
The light will stay on if the parking brake does not fully
release. If it stays on after the parking brake is fully
released, it means there is a brake problem.
If the light comes on while driving, carefully pull off the
road and stop. The pedal may be harder to push or
may go closer to the oor. It may take longer to stop.
If the light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 4-28. United States

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briey when the engine
is started.
If the light stays on, turn the ignition to LOCK/OFF or if
the light comes on, stop as soon as possible and
turn the ignition off. Then start the engine again to reset
the system. If the light still stays on, or comes on again
while driving, the vehicle needs service. See your
dealer/retailer. If the regular brake system warning light
is not on, the brakes will still work, but the antilock
brakes will not work. If the regular brake system warning
light is also on, the antilock brakes will not work
and there is a problem with the regular brakes.
SeeBrake System Warning Light on page 3-28.
The ABS warning light will come on briey when the
ignition is turned to ON/RUN. This is normal. If the light
does not come on then, have it xed so it will be
ready to warn if there is a problem.
Hold Mode Light
If the vehicle has this
feature, this light comes on
when the hold mode is
active.
If the HOLD mode light ashes, have the vehicle checked.
See “Hold Mode” underAutomatic Transmission
Operation on page 2-20for more information.
Engine Coolant Temperature Gage
The vehicle may have an engine coolant temperature
gage. With the ignition turned to ON/RUN, this gage
shows the engine coolant temperature.

Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It makes sure that emissions are at acceptable levels
for the life of the vehicle, helping to produce a cleaner
environment.
This light comes on when
the ignition is on, but the
engine is not running,
as a check to show it is
working. If it does not,
have the vehicle serviced
by your dealer/retailer.
If the check engine light comes on and stays on,
while the engine is running, this indicates that there is
an OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Heeding the light can prevent
more serious damage to the vehicle. This system
assists the service technician in correctly diagnosing
any malfunction.Notice:If the vehicle is continually driven with
this light on, after a while, the emission controls
might not work as well, the vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by the vehicle warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of
the vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a
required Emission Inspection/Maintenance test.
SeeAccessories and Modifications on page 5-3.
This light comes on during a malfunction in one of
two ways:
Light Flashing:A misre condition has been detected.
A misre increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
