2006 CHEVROLET HHR warning light

Up-Shift Light
Your vehicle may have an up-shift light. When this light
comes on, you should shift to the next higher gear if
weather, road, and traffic conditions allow you to.
This light is located in your
instrument panel cluster to
the left of the tachometer.
SeeManual Transaxle Operation on page 2-30for more
information.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on briey when you turn the
ignition key to RUN. If it does not come on then, have it
xed so it will be ready to warn you if there is a problem. United States Only

When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake does not
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
If the light comes on while you are driving, pull off the
road and stop carefully. Make sure the parking brake is
fully released. You may notice that the pedal is harder
to push or, the pedal 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 4-37.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed for
service.
Anti-Lock Brake System
Warning Light
If your vehicle is equipped
with the anti-lock brake
system, the light will come
on when your engine is
started and may stay on for
several seconds. That is
normal.
If the light stays on, turn the ignition the off. If the light
comes on when you are driving, 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
after driving at a speed of at least 13 mph (20 km/h),
or comes on again while you are driving, your vehicle
needs service. If the regular brake system warning light
is not on, you still have brakes, but you do not have
anti-lock brakes. If the regular brake system warning
light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes.
SeeBrake System Warning Light on page 3-32.
The anti-lock brake system warning light will come on
briey when you turn the ignition key to RUN. This is
normal. If the light does not come on then, have it xed
so it will be ready to warn you if there is a problem.

Enhanced Traction System
Warning Light
If your vehicle is equipped
with the Enhanced
Traction System (ETS),
this warning light should
come on briey as
you start the engine.
If the warning light does not come on, then have it xed
so it will be ready to warn you if there is a problem.
If the warning light stays on, or comes on when you are
driving, there may be a problem with your Enhanced
Traction System and your vehicle may need service.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
SeeEnhanced Traction System (ETS) on page 4-10for
more information.
Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning light
will come on when the
engine has overheated.
If this happens you should pull over and turn off the
engine as soon as possible. SeeEngine Overheating on
page 5-23for more information.
Notice:Driving with the engine coolant temperature
warning light on could cause your vehicle to
overheat. SeeEngine Overheating on page 5-23.
Your vehicle could be damaged, and it might not be
covered by your warranty. Never drive with the
engine coolant temperature warning light on.
This light will also come on when starting your vehicle.
If it doesn’t, have your vehicle serviced.

DIC Warnings and Messages
These warning messages will appear in the DIC display
if there is a problem detected in one of your vehicle’s
systems. With most messages, a warning chime
will sound when the message is displayed.
The messages will clear from the display when the
condition no longer exists. You can also acknowledge
and clear some messages from the display by pressing
and holding either the reset or information buttons.
The message will come back on the next time the
vehicle is turned off and back on if the condition still
exists. Your vehicle may have other warning messages.
AUTO (Automatic) LIGHTS OFF
This message will display if the automatic headlamp
system is disabled with the headlamp switch.
SeeAutomatic Headlamp System on page 3-15for
more information.
AUTO (Automatic) LIGHTS ON
This message will display if the automatic headlamp
system is enabled with the headlamp switch.
SeeAutomatic Headlamp System on page 3-15for
more information.
BRAKE FLUID
This message will display to inform the driver that the
brake uid level is low while the ignition is on. Have the
brake system serviced by your GM dealer as soon
as possible.
CHANGE OIL SOON
This message will display when the life of the engine oil
has expired and it should be changed.
When you acknowledge the CHANGE OIL SOON
message by clearing it from the display, you still must
reset the engine oil life system separately. SeeEngine
Oil Life System on page 5-16andScheduled
Maintenance on page 6-4for more information.
CHECK GAS CAP
This message will display if the gas cap has not been
fully tightened. You should recheck your gas cap to
make sure that it is on properly. A few driving trips with
the cap properly installed should turn the message off.
CRUISE ENGAGED
This message will display when the cruise control
system is active. SeeCruise Control on page 3-11for
more information.

Control of a Vehicle
You have three systems that make your vehicle go
where you want it to go. They are the brakes, the
steering, and the accelerator. All three systems have
to do their work at the places where the tires meet
the road.
Sometimes, as when you are driving on snow or ice,
it is easy to ask more of those control systems than the
tires and road can provide. That means you can lose
control of your vehicle. SeeEnhanced Traction System
(ETS) on page 4-10.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modifications
on page 5-3.
Braking
SeeBrake System Warning Light on page 3-32.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That is perception time. Then you have to bring up your
foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three-fourths of a
second, a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement or
gravel; the condition of the road, whether it is wet, dry, or
icy; tire tread; the condition of your brakes; the weight of
the vehicle; and the amount of brake force applied.
4-6

Avoid needless heavy braking. Some people drive in
spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modifications
on page 5-3.Anti-Lock Brake System (ABS)
Your vehicle may have the Anti-Lock Brake System
(ABS), an advanced electronic braking system that will
help prevent a braking skid.
If your vehicle has ABS,
this warning light on the
instrument panel will come
on briey when you
start your vehicle.
When you start your engine, or when you begin to drive
away, your ABS will check itself. You may hear a
momentary motor or clicking noise while this test is
going on, and you may even notice that your brake
pedal moves or pulses a little. This is normal.
4-7

Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if
it senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may
also upshift the transaxle to limit wheel spin. You may
feel or hear the system working, but this is normal.
A LOW TRACTION message will appear on the Driver
Information Center (DIC) when the traction control
system is actively limiting wheel spin. Slippery road
conditions may exist if this message is displayed,
so adjust your driving accordingly.
If your vehicle is in cruise control when the Enhanced
Traction System begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. SeeCruise Control
on page 3-11.
When the system is on,
this warning light will
come on to let you know
there’s a problem.The Enhanced Traction System warning light may come
on for the following reasons:If you turn the system off by moving the shift lever
to LOW (L), the warning light will come on and
stay on. To turn the system back on, move the shift
lever back to a position other than LOW (L).
The warning light should go off.
The warning light will come on when you set your
parking brake with the engine running, and it will
stay on if your parking brake does not release fully.
If the transaxle shift lever is in any position other
than LOW (L)and the warning light stays on
after your parking brake is fully released, it means
there is a problem with the system.
If the traction control system is affected by an
engine related problem, the system will turn off and
the warning light will come on.
If the warning light stays on, or comes on when you’re
driving, there may be a problem with your Enhanced
Traction System and your vehicle may need service.
When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
If the Enhanced Traction System warning light comes
on and stays on for an extended period of time when
the transaxle shift lever is in any position other than
LOW (L), your vehicle needs service.
4-10

To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction System on. But you can turn the system off
if you prefer.
To turn the system off, shift to LOW (L) or REVERSE (R).
When you turn the system off, the Enhanced Traction
System warning light will come on and stay on when the
gear shift is in LOW (L). The warning light will not come
on when the gear shift is in REVERSE (R). If the
Enhanced Traction System is limiting wheel spin when
you shift to LOW (L) or REVERSE (R) to turn the system
off, the warning light will come on in LOW (L). But the
system won’t turn off right away. It will wait until there’s no
longer a current need to limit wheel spin.
You can turn the system back on at any time by
shifting to AUTOMATIC OVERDRIVE (D) or
INTERMEDIATE (I). The Enhanced Traction System
warning light should go off.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modifications
on page 5-3for more information.Steering
Electric Power Steering
If the engine stalls while you are driving, the power
steering assist system will continue to operate until you
are able to stop your vehicle. If you lose power
steering assist because the electric power steering
system is not functioning, you can steer, but it will take
more effort.
If you turn the steering wheel in either direction several
times until it stops, or hold the steering wheel in the
stopped position for an extended amount of time, you
may notice a reduced amount of power steering
assist. The normal amount of power steering assist
should return shortly after a few normal steering
movements.
The electric power steering system does not require
regular maintenance. If you suspect steering system
problems and/or the POWER STEERING message
comes on, contact your dealer for service repairs.
