Brake System Warning Light
The vehicle brake system consists of two hydraulic
circuits. If one circuit is not working, the remaining
circuit can still work to stop the vehicle. For normal
braking performance, both circuits need to be working.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
EnglishMetric
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 5‑28.
{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.
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 4‑29.
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages
on page 4‑40for all
brake related DIC messages.
Enhanced Traction System (ETS)
Indicator/Warning Light

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.
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

Engine Coolant Temperature
Warning Light
This light comes on briefly
while starting the vehicle.
If it does not, have the vehicle serviced by the dealer.
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. See Engine Overheating
on page 6‑28.
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. See Engine Overheating
on page 6‑28for
more information.
Engine Coolant Temperature Gauge
The vehicle has an
engine coolant
temperature gauge. With
the ignition turned to ON/
RUN, this gauge 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 6‑28.

Tire Pressure Light
For vehicles with the 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 are
significantly underinflated.
Stop and check the tires as soon as it is safe to do, and
inflate them to the proper pressure. See Tires
on
page 6‑47for more information.
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 then stays on steady for the remainder of
the ignition cycle. This sequence will repeat with every
ignition cycle. See Tire Pressure Monitor System
on
page 6‑55for more information.
Malfunction Indicator Lamp
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.
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.
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 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.
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.
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.
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 the vehicle off, wait at least 10 seconds, and
restart the engine. If the light is still flashing, follow the
previous steps and see your dealer 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.
4-34
Page 191 of 430

Black plate (35,1)Chevrolet HHR Owner Manual - 2011
.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, 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.
SeeGasoline Octane on page 6‑6.
If none of the above have made the light turn off, your
dealer can check the vehicle. The dealer 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 may have
programs to inspect the on-vehicle emission control
equipment For the inspection, the emission system test
equipment is connected to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument panel to the left of the
steering wheel. See your dealer if assistance is needed.
The vehicle may not pass inspection if:
.the Malfunction Indicator Lamp is on with the
engine running, or if the light does not come on
when the ignition is turned to ON/RUN while the
engine is off.
.the critical emission control systems have not been
completely diagnosed by the system. This can
happen if the battery has recently been replaced or
if the battery has run down. The diagnostic system
evaluates 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, your
dealer can prepare the vehicle for inspection.
