ABS CHEVROLET HHR 2009 1.G User Guide

Under certain weather or operating conditions, occasional
brake squeak, squeal, or other noise might be heard with
the vehicle’s performance braking system. The brake
system on SS models is designed for superior fade
resistance and consistent operation using high
performance brake pads. Brake noise and brake dust
are normal and do not affect system performance.
Adding non-dealer/non-retailer accessories can affect
vehicle performance. SeeAccessories and Modifications
on page 5-3.
Antilock Brake System (ABS)
The vehicle might have the Antilock Brake System
(ABS), an advanced electronic braking system that helps
prevent a braking skid.
If the vehicle has ABS,
this warning light on the
instrument panel comes on
briey when the vehicle is
started.When the engine is started, or when the vehicle begins
to drive away, ABS checks itself. A momentary motor
or clicking noise might be heard while this test is going
on, and it might even be noticed that the brake pedal
moves or pulses a little. This is normal.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that the wheels are slowing down.
If one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.
ABS can change the brake pressure to each wheel, as
required, faster than any driver could. This can help
the driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps
receiving updates on wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change the time needed to get
a foot up to the brake pedal or always decrease stopping
distance. If you get too close to the vehicle in front of you,
there will not be enough time to apply the brakes if that
vehicle suddenly slows or stops. Always leave enough
room up ahead to stop, even with ABS.

Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work. A slight brake pedal
pulsation might be felt or some noise noticed, but this is
normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If the vehicle has Electronic Stability Control (ESC) with
Antilock Brake System (ABS), it allows the driver to steer
and brake at the same time. However, if the vehicle does
not have ESC with ABS, the rst reaction — to hit the
brake pedal hard and hold it down — might be the wrong
thing to do. The wheels can stop rolling. Once they do,
the vehicle cannot respond to the driver’s steering.
Momentum will carry it in whatever direction it was
headed when the wheels stopped rolling. That could be
off the road, into the very thing the driver was trying to
avoid, or into traffic.
If the vehicle does not have ABS, use a “squeeze”
braking technique. This gives maximum braking while
maintaining steering control. Do this by pushing on
the brake pedal with steadily increasing pressure.In an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If you hear or feel
the wheels sliding, ease off the brake pedal. This helps
retain steering control. Without ABS, it is different.
SeeAntilock Brake System (ABS) on page 4-5.
In many emergencies, steering can help more than
even the very best braking.Brake Assist
If this vehicle has ESC with ABS, it also has a Brake
Assist feature designed to assist the driver in stopping
or decreasing vehicle speed in emergency driving
conditions. This feature uses the stability system
hydraulic brake control module to supplement the
power brake system under conditions where the driver
has quickly and forcefully applied the brake pedal in
an attempt to quickly stop or slow down the vehicle.
The stability system hydraulic brake control module
increases brake pressure at each corner of the vehicle
until the ABS activates. Minor brake pedal pulsations
or pedal movement during this time is normal and the
driver should continue to apply the brake pedal as the
driving situation dictates The Brake Assist feature will
automatically disengage when the brake pedal is
released or brake pedal pressure is quickly decreased.

To turn the system off or
on, press and release the
ESC/TCS button located
on the instrument panel.
The DIC displays the appropriate message as described
previously when the button is pressed.
Traction Control Operation
Traction control limits wheel spin by reducing engine
power to the wheels (engine speed management)
and by applying brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is enabled automatically
when the vehicle is started, and it will activate and ash
the ESC/TCS light and display the LOW TRACTION
message if it senses that either of the front wheels are
spinning or beginning to lose traction while driving.
For more information on the LOW TRACTION message,
seeDriver Information Center (DIC) on page 3-48.
Notice:If the wheel(s) of one axle are allowed
to spin excessively while the ESC/TCS, ABS and
Brake warning lights and the SERVICE ESC and/or
SERVICE TRACTION messages are displayed, thedifferential could be damaged. The repairs would not
be covered by the vehicle warranty. Reduce engine
power and do not spin the wheel(s) excessively while
these lights and this message are displayed.
Notice:When traction control is turned off, or
Competitive Driving Mode is active, it is possible to
lose traction. If you attempt to shift with the drive
wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not attempt
to shift when the drive wheels do not have traction.
Damage caused by misuse of the vehicle is not
covered. See the warranty book for additional
information.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens, a reduction
in acceleration may be noticed or a noise or vibration
may be heard. This is normal.
If the vehicle is in cruise control while the system
activates, the ESC/TCS light ashes and the cruise
control automatically disengages. The cruise control can
be re-engaged when road conditions allow. SeeCruise
Control on page 3-10.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
4-11

Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not overdriving
those conditions. But skids are always possible.
The three types of skids correspond to the vehicle’s three
control systems. In the braking skid, the wheels are not
rolling. In the steering or cornering skid, too much speed
or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid, too much
throttle causes the driving wheels to spin.
If the vehicle has the Traction Control System (TCS) or
the Enhanced Traction System (ETS), remember: It helps
to avoid only the acceleration skid. SeeTraction Control
System (TCS) on page 4-10orEnhanced Traction
System (ETS) on page 4-12. If the vehicle does not have
TCS or ETS, or if the system is off, then an acceleration
skid is best handled by easing your foot off the
accelerator pedal.
If the vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
the vehicle may straighten out. Always be ready for
a second skid if it occurs.If the vehicle has Electronic Stability Control (ESC), the
ESC might activate. SeeElectronic Stability Control
(ESC) on page 4-7.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, slow
down and adjust your driving to these conditions. It is
important to slow down on slippery surfaces because
stopping distance will be longer and vehicle control
more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by shifting
to a lower gear. Any sudden changes could cause the
tires to slide. You may not realize the surface is slippery
until the vehicle is skidding. Learn to recognize warning
clues — such as enough water, ice, or packed snow on
the road to make a mirrored surface — and slow down
when you have any doubt.
If the vehicle has the Antilock Brake System (ABS),
remember: It helps avoid only the braking skid. If the
vehicle does not have ABS, then in a braking skid,
where the wheels are no longer rolling, release enough
pressure on the brakes to get the wheels rolling again.
This restores steering control. Push the brake pedal down
steadily when you have to stop suddenly. As long as the
wheels are rolling, you will have steering control.
4-17

Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow or ice between the
tires and the road, creating less traction or grip. Wet ice
can occur at about 32°F (0°C) when freezing rain begins
to fall, resulting in even less traction. Avoid driving on wet
ice or in freezing rain until roads can be treated with salt
or sand.
Drive with caution, whatever the condition. Accelerate
gently so traction is not lost. Accelerating too quickly
causes the wheels to spin and makes the surface under
the tires slick, so there is even less traction.
Try not to break the fragile traction. If you accelerate too
fast, the drive wheels will spin and polish the surface
under the tires even more.
If the vehicle has theTraction Control System (TCS) on
page 4-10orEnhanced Traction System (ETS) on
page 4-12, it improves the ability to accelerate on slippery
roads, but slow down and adjust your driving to the road
conditions. When driving through deep snow, turn off the
traction system to help maintain vehicle motion at lower
speeds.TheAntilock Brake System (ABS) on page 4-5improves
vehicle stability during hard stops on a slippery roads, but
apply the brakes sooner than when on dry pavement.
Allow greater following distance on any slippery road
and watch for slippery spots. Icy patches can occur on
otherwise clear roads in shaded areas. The surface
of a curve or an overpass can remain icy when the
surrounding roads are clear. Avoid sudden steering
maneuvers and braking while on ice.
Turn off cruise control, if equipped, on slippery surfaces.
Blizzard Conditions
Being stuck in snow can be in a serious situation. Stay
with the vehicle unless there is help nearby. If possible,
use theRoadside Assistance Program on page 7-7.
To get help and keep everyone in the vehicle safe:
Turn on theHazard Warning Flashers on page 3-6.
Tie a red cloth to an outside mirror.
4-22

Driving on Grades
Notice:Do not tow on steep continuous grades
exceeding 6 miles (9.6 km). Extended, higher than
normal engine and transmission temperatures may
result and damage the vehicle. Frequent stops are
very important to allow the engine and transmission
to cool.
When towing under severe conditions such as hot
ambient temperatures or steep grades, the vehicle may
experience more transmission shifting. A COOLING
MODE ON message may also appear in the DIC.
This alerts the driver that the shifting mode is in progress
and is aiding engine cooling. SeeDIC Warnings and
Messages on page 3-50DIC Warnings and Messages
for more information.
Reduce speed and shift to a lower gearbeforestarting
down a long or steep downgrade. If the transmission is
not shifted down, the brakes might have to be used so
much that they would get hot and no longer work well.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning to reduce
engine load. SeeEngine Overheating on page 5-32.
Parking on Hills
{CAUTION:
Parking the vehicle on a hill with the trailer
attached can be dangerous. If something goes
wrong, the rig could start to move. People can be
injured, and both the vehicle and the trailer can be
damaged. When possible, always park the rig on a
at surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park)
yet. Turn the wheels into the curb if facing downhill
or into traffic if facing uphill.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
brake pedal until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking
brake and shift into P (Park).
5. Release the brake pedal.

Taillamps, Turn Signal, Stoplamps
and Back-up Lamps
A. Stoplamp/Taillamp/Turn Signal Lamp
B. Back-up LampTo replace one of these bulbs:
1. Open the liftgate. SeeLiftgate on page 2-12.
2. Remove the cover in the rear cargo area of the
vehicle to access the bulbs.
3. Turn the bulb socket counterclockwise and pull it
straight out of the lamp assembly.
4. Pull the bulb straight out of the socket.
5. Install a new bulb. When installing the bulb socket
into the assembly, line up the tabs with the slots in
the bulb assembly.
5-50

Do not clean the vehicle using:
A knife or any other sharp object to remove a soil
from any interior surface.
A stiff brush. It can cause damage to the vehicle’s
interior surfaces.
Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage
the interior and does not improve the effectiveness
of soil removal.
Laundry detergents or dishwashing soaps with
degreasers can leave residue that streaks and
attracts dirt. For liquid cleaners, about 20 drops
per gallon (3.78 L) of water is a good guide.
Use only mild, neutral-pH soaps.
Too much cleaner that saturates the upholstery.
Organic solvents such as naptha, alcohol, etc. that
can damage the vehicle’s interior.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be used
on oor carpet and carpeted oor mats. For any soil,
always try to remove it rst with plain water or club soda.
Before cleaning, gently remove as much of the soil as
possible using one of the following techniques:
For liquids: gently blot the remaining soil with a paper
towel. Allow the soil to absorb into the paper towel
until no more can be removed.
For solid dry soils: remove as much as possible and
then vacuum.
To clean:
1. Saturate a lint-free, clean white cloth with water or
club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub
toward the center. Continue cleaning, using a clean
area of the cloth each time it becomes soiled.
