CHEVROLET HHR 2009 1.G Owners Manual

Passenger Airbag Status Indicator
The vehicle has the passenger sensing system.
SeePassenger Sensing System (Without Turbo/With
Turbo and RPO AS5) on page 1-66orPassenger
Sensing System (With Turbo and RPO AR9 or AE4) on
page 1-72for important safety information. The
instrument panel has a passenger airbag status indicator.
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. If you are
using remote start to start the vehicle from a distance, if
equipped, you may not see the 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 airbag.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 is enabled (may inate).
If the word OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger sensing
system has turned off the right front passenger
frontal airbag.
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 3-30
for more information, including important safety
information. United StatesCanada

Charging System Light
This light comes on briey
when the ignition key is
turned on, but the engine is
not running, as a check
to show it is working.
It should go out once the engine is running. If it stays on,
or comes on while driving, there could be a problem with
the charging system or it could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light on,
to turn off the accessories, such as the radio and air
conditioner.
Up-Shift Light
The vehicle may have an
up-shift light.
When this light comes on, shift to the next higher gear if
weather, road, and traffic conditions allow.
SeeManual Transmission Operation on page 2-30for
more information.
3-32

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.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
This light should come on briey when the engine is
started. 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
also comes on when the parking brake is set. The light
stays on if the parking brake does not fully release. If it
stays on after the parking brake is fully released, it means
the vehicle has a brake problem.
If the light comes on while driving, pull off the road
and stop carefully. Make sure the parking brake is fully
released. The pedal might be harder to push or, the pedal
could go closer to the oor. It can take longer to stop.
Try turning off and restarting the vehicle one or two times,
if the light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 4-31.
{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. United StatesCanada

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 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. SeeBrake System Warning Light on
page 3-33.
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 3-50for all
brake related DIC messages.
Enhanced Traction System (ETS)
Indicator/Warning Light
For vehicles with the
Enhanced Traction System
(ETS), this light serves
as an indicator and
warning light.
This light comes on briey while 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 indicator/warning light is on and not ashing, the
ETS system could have been disabled. Check all related
Driver Information Center (DIC) messages to determine
whether the system has been turned off or if the system
is not working properly and the vehicle requires service.
If the ETS has been disabled, wheel spin is not limited.
If the indicator/warning light is on and ashing, the ETS
is actively working. The LOW TRACTION DIC message
also appears when the system is actively limiting
wheel spin.

The Electronic Stability
Control (ESC) system
or the Traction Control
System (TCS) indicator/
warning light comes on
briey when the engine is
started.
If it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally the
indicator light goes off.
This light, along with the appropriate Driver Information
Center (DIC) messages, indicates when the ESC
system and the TCS are working or are disabled.If the light comes on and stays on, the TCS and
potentially the ESC system have been disabled.
Check the DIC messaging to determine which system is
turned off, or not working. If the system is not working,
the vehicle needs service. See your dealer/retailer.
When the TCS is disabled, wheel spin is not limited.
When the ESC system is disabled, the system does not
aid in maintaining vehicle directional control.
If the light comes on and ashes, the TCS or the ESC
system is actively working. When the LOW TRACTION
message appears, the system is limiting wheel spin.
When the ESC ACTIVE message appears, the system
is aiding in maintaining vehicle directional control.

Engine Coolant Temperature
Warning Light
This light comes on briey
while starting the vehicle.
If it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally the
indicator light goes off.
Notice:Driving with the engine coolant temperature
warning light on could cause the vehicle to overheat.
SeeEngine Overheating on page 5-32. The vehicle’s
engine could be damaged, and it might not be
covered by the vehicle warranty. Never drive with
the engine coolant temperature warning light on.
The engine coolant temperature warning light comes on
when the engine has overheated.
If this happens pull over and turn off the engine as soon
as possible. SeeEngine Overheating on page 5-32
for more information.
Engine Coolant Temperature Gage
The vehicle has an engine
coolant temperature gage.
With the ignition turned to
ON/RUN, this gage shows
the engine coolant
temperature.
If the gage pointer moves into the red area, the engine
is too hot because the engine coolant has overheated.
If the vehicle is operating under normal driving
conditions, pull off the road, stop the vehicle and
turn off the engine as soon as possible.
SeeEngine Overheating on page 5-32.
3-36

Tire Pressure Light
For vehicles with a tire
pressure monitoring
system, this light comes
on briey 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 signicantly
underinated.
A tire pressure message in the Driver Information Center
(DIC), can accompany the light. SeeDIC Warnings and
Messages on page 3-50for more information. Stop and
check the tires as soon as it is safe to do so. If a tire is
underinated, inate to the proper pressure. SeeTires
on page 5-53for more information.
When the Light Flashes First and Then is
On Steady
This indicates that there could be a problem with the Tire
Pressure Monitor System. The light ashes for about a
minute and stays on steady for the remainder of the
ignition cycle. This sequence repeats with every ignition
cycle. SeeTire Pressure Monitor System on page 5-62
for 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 ensures that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment.
3-37

This light should come 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. 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: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. See
Accessories 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.
To prevent more serious damage to the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the amount of cargo being
hauled as soon as it is possible.
3-38

If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the key off, wait at least 10 seconds, and restart
the engine. If the light is still ashing, 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. SeeFilling
the Tank on page 5-9. 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 can cause: stalling after start-up,
stalling when the vehicle is changed into gear,
misring, 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.
SeeGasoline Octane on page 5-5.
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
x any mechanical or electrical problems that might have
developed.
3-39

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, or if the
key is in ON/RUN and the light is not on.
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.
Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
