2010 CHEVROLET HHR Owners Manual

Airbag Readiness Light
The system checks the airbag's electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the
airbag modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, seeAirbag System on page 2‑60.
The airbag readiness
light flashes for a few
seconds when the engine
is started. If the light does
not come on then, have it
fixed immediately.
{WARNING:
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
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also
come on. See DIC Warnings and Messages
on
page 4‑48for more information.

Passenger Airbag Status Indicator
If the vehicle has one of the passenger airbag status
indicators pictured in the following illustrations, then the
vehicle has a passenger sensing system for the right
front passenger position. The passenger airbag status
indicator, if equipped, is on the instrument panel. See
Passenger Sensing System
on page 2‑70for important
safety information.
In addition, if the vehicle has a passenger sensing
system for the right front passenger position, the label
on the vehicle's sun visors refer to “ADVANCED
AIRBAGS”.
United StatesCanada
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 using remote start, if equipped, to start the vehicle
from a distance, 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 inflate).
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.
{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 4‑27
for more information, including important safety
information.

Charging System Light
This light comes on briefly
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.

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.
United StatesCanada
This light should come on briefly when the engine is
started. If it does not come on then, have it fixed 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 floor. 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. See
Towing Your Vehicle on page 5‑29.
{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.

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
Warning Light on page 4‑30.
For vehicles with a Driver Information Center (DIC),
see DIC Warnings and Messages
on page 4‑48for
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 briefly 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 flashing, 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 flashing, the ETS
is actively working. The LOW TRACTION DIC message
also appears when the system is actively limiting
wheel spin.

Electronic Stability Control (ESC)/
Traction Control System (TCS)
Indicator/Warning Light
The Electronic Stability
Control (ESC) system
or the Traction Control
System (TCS)
indicator/warning light
comes on briefly 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 flashes, 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.

shows the engine coolant
temperature.
If the gauge 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.
See Engine Overheating on page 6‑34.
