Passenger Airbag Status Indicator
The vehicle has the passenger sensing system. See
Passenger Sensing Systemon page 2‑53for important
safety information. The rearview mirror has a passenger
airbag status indicator.
United States
Canada 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 to let you know
the status of the right front passenger frontal and
seat-mounted side impact airbags (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 inflate).
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). See
Passenger Sensing System
on
page 2‑53for more on this, including important safety
information.
4-34

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.
{WARNING:
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. See Airbag Readiness Light
on page 4‑33
for more information, including important safety
information.
Voltmeter Gauge
Base and Z06 The voltmeter shows the
voltage output of the
battery. It shows the
voltage output of the
charging system while
the engine is running.
The reading changes as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, the instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) reads BATTERY VOLTAGE
LOW when the vehicle is at 10 volts or below. Have it
checked right away. Driving with the voltmeter reading
at 10 volts or below could drain the battery and disable
the vehicle.

One-to-Four Shift Light
(Manual Transmission)
When this light comes on,
the vehicle can only be
shifted from 1 (First) to
4 (Fourth) instead of
1 (First) to 2 (Second).
The shift must be completed into 4 (Fourth) to turn off
this feature. This helps the vehicle get the best possible
fuel economy.
After shifting to 4 (Fourth), the vehicle can be
downshifted to a lower gear.
Notice: Forcing the shift lever into any gear except
4 (Fourth) when the 1 TO 4 SHIFT light comes on
may damage the transmission. Shift only from
1 (First) to 4 (Fourth) when the light comes on. This light comes on when:
.The engine coolant temperature is higher
than 169°F (76°C),
.The vehicle is going 15 to 19 mph
(24 to 31 km/h) and
.The vehicle 21 percent throttle or less.
Brake System Warning Light
The vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can still
work and stop the vehicle. For good braking both parts
need to be working well.

This light comes on briefly while starting the engine. If it
does not come on, have it fixed so it is ready to warn if
there is a problem.
{WARNING:
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.
If this warning light stays on after the engine is started,
the parking brake may still be set or there could be a
brake problem. Refer to Parking Brake
on page 3‑34to
see if it is set. If the parking brake is not set, have the
brake system inspected right away.
If the light comes on while driving and a CHECK
BRAKE FLUID message shows on the DIC, pull off the
road and stop carefully. The pedal may be harder to
push or the pedal may go closer to the floor. It may take
longer to stop. If the light is still on, have the vehicle
towed for service. See Towing Your Vehicle
on
page 5‑33and DIC Warnings and Messageson
page 4‑52for more information.
Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine is
started.
If it does not, have the vehicle serviced by your dealer/
retailer. If the system is working normally the indicator
light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on,
or comes on again while driving, the vehicle needs
service. If the regular brake system warning light is not
on, the vehicle still has brakes, but not antilock brakes.
If the regular brake system warning light is also on, the
vehicle does not have antilock brakes and there is a
problem with the regular brakes. See Brake System

Engine Coolant Temperature Gauge
United StatesCanada
This gauge shows the engine coolant temperature.
If the gauge pointer moves into the shaded area, the
engine is too hot.
This means that the engine coolant has overheated.
If the vehicle has been operating under normal driving
conditions, pull off the road, stop the vehicle and turn off
the engine as soon as possible.
See Engine Overheating
on page 6‑38for more
information.
Tire Pressure Light
For vehicles with a tire
pressure monitoring
system, this light comes
on briefly when the engine
is started. It provides
information about tire
pressures and the Tire
Pressure Monitoring
System.
When the Light is On Steady
This indicates that one or more of the tires is
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. See Driver
Information Center (DIC)
on page 4‑47for more
information. Stop and check the tires as soon as it is
safe to do so. If underinflated, inflate to the proper
pressure. See Inflation - Tire Pressure
on page 6‑70for more information.
4-40

When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light flashes for about a
minute and stays on steady for the remainder of the
ignition cycle. This sequence repeats with every ignition
cycle. See Tire Pressure Monitor Operation
on
page 6‑74for more information.
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 comes on briefly
while starting the engine.
If it does not come on,
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. Being aware of 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: Modifications 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.
Modifications 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. See
Accessories and Modifications on page 6‑3.
4-41

This light comes on during a malfunction in one of
two ways:
Light Flashing : A misfire condition has been detected.
A misfire increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
The following can prevent more serious damage to the
vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn off the ignition, wait at least 10 seconds, and
restart the engine. If the light is still flashing, follow the
previous steps and see your dealer/retailer for service
as soon as possible.
Light On Steady : An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required. An emission system malfunction might be corrected by
doing the following:
.Make sure the fuel cap is fully installed. See
Filling
the Tankon page 6‑9. The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere. A few
driving trips with the cap properly installed should
turn the light off.
.If the vehicle has been driven through a deep
puddle of water, the vehicle's electrical system
might be wet. The condition is usually corrected
when the electrical system dries out. A few driving
trips should turn the light off.
.Make sure to fuel the vehicle with quality fuel.
Poor fuel quality causes the engine not to run as
efficiently as designed and may cause: stalling
after start-up, stalling when the vehicle is changed
into gear, misfiring, hesitation on acceleration,
or stumbling on acceleration. These conditions
might go away once the engine is warmed up.
If one or more of these conditions occurs, change
the fuel brand used. It will require at least one full
tank of the proper fuel to turn the light off.
See Gasoline Octane on page 6‑7.
4-42

If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to fix
any mechanical or electrical problems that might have
developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have
or might begin programs to inspect the emission
control equipment on the vehicle. Failure to pass this
inspection could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
.The vehicle will not pass this inspection if the
check engine light is on with the engine running.
To perform a check engine light bulb check with
the keyless ignition, make sure the transmitter fob
is in the passenger compartment. See Ignition
Positions
on page 3‑23. Press the bottom of the
Acc. button on the instrument panel and hold the button down for five seconds. The instrument
panel, including the check engine light, will light up
and the ignition will be on, but the engine will not
start
—press the bottom of the Acc. button only
briefly, less than five seconds, the accessory
power mode will be turned on, but not the ignition.
After the bulb check, press and release the Acc.
button again to turn the ignition off and avoid
draining the vehicle's battery.
.The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if the battery has
recently been replaced or if the battery has run
down. The diagnostic system is designed to
evaluate critical emission control systems during
normal driving. This can take several days of
routine driving. If this has been done and the
vehicle still does not pass the inspection for lack
of OBD II system readiness, your dealer/retailer
can prepare the vehicle for inspection.
