Steering
Electric Power Steering
If the engine stalls while driving, the power steering
assist system will continue to operate until you are able
to stop the vehicle. If power steering assist is lost
because the electric power steering system is not
functioning, the vehicle can be steered 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. See
DIC Warnings and Messages on page 4‑40.
Steering Tips
It is important to take curves at a reasonable speed.
Traction in a curve depends on the condition of the tires
and the road surface, the angle at which the curve is
banked, and vehicle speed. While in a curve, speed is
the one factor that can be controlled.If there is a need to reduce speed, do it before entering
the curve, while the front wheels are straight.
Try to adjust the speed so you can drive through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until out of the curve, and then accelerate
gently into the straightaway.
Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and
find a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right in front of you. These
problems can be avoided by braking
—if you can stop
in time. But sometimes you cannot stop in time because
there is no room. That is the time for evasive
action —steering around the problem.
The vehicle can perform very well in emergencies like
these. First apply the brakes —but, unless the vehicle
has antilock brakes, not enough to lock the wheels. See
Braking
on page 5‑3. It is better to remove as much
speed as possible from a collision. Then steer around
the problem, to the left or right depending on the space
available.

Passing
Passing another vehicle on a two-lane road can be
dangerous. To reduce the risk of danger while passing:
.Look down the road, to the sides, and to
crossroads for situations that might affect a
successful pass. If in doubt, wait.
.Watch for traffic signs, pavement markings, and
lines that could indicate a turn or an intersection.
Never cross a solid or double‐solid line on your
side of the lane.
.Do not get too close to the vehicle you want to
pass. Doing so can reduce your visibility.
.Wait your turn to pass a slow vehicle.
.When you are being passed, ease to the right.
Loss of Control
Let us review what driving experts say about what
happens when the three control systems—brakes,
steering, and acceleration —do not have enough
friction where the tires meet the road to do what the
driver has asked.
In any emergency, do not give up. Keep trying to steer
and constantly seek an escape route or area of less
danger.
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. See Traction
Control System (TCS)
on page 5‑8or Enhanced
Traction System (ETS)on page 5‑10. 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.
5-14

Black plate (15,1)Chevrolet HHR Owner Manual - 2011
If the vehicle has Electronic Stability Control (ESC), the
ESC might activate. SeeElectronic Stability Control
(ESC) on page 5‑6.
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.Racing or Other Competitive Driving
See your warranty book before using your vehicle for
racing or other competitive driving. After reviewing your
warranty book, please see the GM Performance Parts
website or catalog and contact the race sanctioning
bodies, for example Sports Car Club of America
(SCCA) or Grand American, for parts and equipment
required for racing or other competitive driving.
Notice: If you use your vehicle for competitive
driving, the engine may use more oil than it would
with normal use. Low oil levels can damage the
engine. Be sure to check the oil level often during
competitive driving and keep the level at or near the
upper mark that shows the proper operating range
on the engine oil dipstick. For information on how to
add oil, see Engine Oil on page 6‑16.

Hydroplaning
Hydroplaning is dangerous. Water can build up under
your vehicle's tires so they actually ride on the water.
This can happen if the road is wet enough and you are
going fast enough. When your vehicle is hydroplaning, it
has little or no contact with the road.
There is no hard and fast rule about hydroplaning. The
best advice is to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather driving tips
include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment in good shape.
.Keep the windshield washer fluid reservoir filled.
.Have good tires with proper tread depth. SeeTireson page 6‑47.
.Turn off cruise control.
Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer before departing.
Things to check on your own include:
.Windshield Washer Fluid:Reservoir full? Windows
clean —inside and outside?
.Wiper Blades: In good shape?
.Fuel, Engine Oil, Other Fluids: All levels checked?
.Lamps:Do they all work and are lenses clean?
.Tires:Are treads good? Are tires inflated to
recommended pressure?
.Weather and Maps: Safe to travel? Have
up-to-date maps?

Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, find a safe
place to park your vehicle and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep interior temperature cool.
.Keep your eyes moving—scan the road ahead
and to the sides.
.Check the rearview mirror and vehicle instruments
often.
Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on flat or rolling terrain. Tips for driving in
these conditions include:
.Keep the vehicle serviced and in good shape.
.Check all fluid levels and brakes, tires, cooling
system, and transmission.
.Going down steep or long hills, shift to a
lower gear.
{WARNING:
If you do not shift down, the brakes could get so
hot that they would not work well. You would then
have poor braking or even none going down a hill.
You could crash. Shift down to let the engine
assist the brakes on a steep downhill slope.
{WARNING:
Coasting downhill in N (Neutral) or with the
ignition off is dangerous. The brakes will have to
do all the work of slowing down and they could
get so hot that they would not work well. You
would then have poor braking or even none going
down a hill. You could crash. Always have the
engine running and the vehicle in gear when
going downhill.
.Stay in your own lane. Do not swing wide or cut
across the center of the road. Drive at speeds that
let you stay in your own lane.
5-18

.Top of hills: Be alert—something could be in your
lane (stalled car, accident).
.Pay attention to special road signs (falling rocks
area, winding roads, long grades, passing or
no-passing zones) and take appropriate action.
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 0°C (32°F) 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 the
Traction Control System (TCS)
on
page 5‑8or Enhanced Traction System (ETS)on
page 5‑10, 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.
The Antilock Brake System (ABS)
on page 5‑4improves 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.

To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine
off and close the window most of the way to save heat.
Repeat this until help arrives but only when you feel
really uncomfortable from the cold. Moving about to
keep warm also helps.
If it takes some time for help to arrive, now and then
when you run the engine, push the accelerator pedal
slightly so the engine runs faster than the idle speed.
This keeps the battery charged to restart the vehicle
and to signal for help with the headlamps. Do this as
little as possible to save fuel.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
Slowly and cautiously spin the wheels to free the
vehicle when stuck in sand, mud, ice, or snow. See
Rocking Your Vehicle to Get It Out on page 5‑21.
If the vehicle has a traction system, it can often help to
free a stuck vehicle. Refer to the vehicle's traction
system in the Index. If stuck too severely for the traction
system to free the vehicle, turn the traction system off
and use the rocking method.
{WARNING:
If the vehicle's tires spin at high speed, they can
explode, and you or others could be injured. The
vehicle can overheat, causing an engine
compartment fire or other damage. Spin the
wheels as little as possible and avoid going above
55 km/h (35 mph) as shown on the speedometer.
For information about using tire chains on the vehicle,
see Tire Chains on page 6‑68.
Rocking Your Vehicle to Get It Out
Turn the steering wheel left and right to clear the area
around the front wheels. Turn off any traction system.
Shift back and forth between R (Reverse) and a forward
gear, or with a manual transmission, between 1 (First) or
2 (Second) and R (Reverse), spinning the wheels as
little as possible. To prevent transmission wear, wait
until the wheels stop spinning before shifting gears.
Release the accelerator pedal while shifting, and press
lightly on the accelerator pedal when the transmission is
in gear. Slowly spinning the wheels in the forward and

The Tire and Loading Information label also lists
the tire size of the original equipment tires (C) and
the recommended cold tire inflation pressures (D).
For more information on tires and inflation, see
Tires
on page 6‑47andInflation - Tire Pressureon
page 6‑54
.
There is also important loading information on the
Certification/Tire label. It tells you the Gross
Vehicle Weight Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for the front and rear
axles. See “Certification/Tire Label” later in this
section.
Steps for Determining Correct Load Limit
1.Locate the statement “The combined weight
of occupants and cargo should never exceed
XXX kg or XXX lbs” on your vehicle's placard.
2.Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the“XXX”amount equals
1400 lbs and there will be five 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs (1400 −750 (5 x 150) = 650 lbs).
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated in
Step 4.
6.If your vehicle will be towing a trailer, the load
from your trailer will be transferred to your
vehicle. Consult this manual to determine
how this reduces the available cargo and
luggage load capacity for your vehicle.
If your vehicle can tow a trailer, see Towing a
Trailer (Automatic Transmission)
on page 5‑31or
Towing a Trailer (Manual Transmission)
on
page 5‑37
for important information on towing a
trailer, towing safety rules, and trailering tips.

Certification Label
A vehicle specific Certification/Tire label is found
on the rear edge of the driver's door, or on the
vehicle's center pillar (B‐pillar).The label shows the size of your original tires and
the inflation pressures needed to obtain the gross
weight capacity of your vehicle. This is called the
Gross Vehicle Weight Rating (GVWR). The
GVWR includes the weight of the vehicle, all
occupants, fuel, and cargo.
The Certification/Tire label also tells you the
maximum weights for the front and rear axles,
called the Gross Axle Weight Rating (GAWR). To
find out the actual loads on your front and rear
axles, you need to go to a weigh station and
weigh your vehicle. Your dealer can help you with
this. Be sure to spread out your load equally on
both sides of the centerline.
Never exceed the GVWR for your vehicle or the
GAWR for either the front or rear axle.

Towing a Trailer (Automatic
Transmission)
{WARNING:
The driver can lose control when pulling a trailer if
the correct equipment is not used or the vehicle is
not driven properly. For example, if the trailer is
too heavy, the brakes may not work well—or
even at all. The driver and passengers could be
seriously injured. The vehicle may also be
damaged; the resulting repairs would not be
covered by the vehicle warranty. Pull a trailer only
if all the steps in this section have been followed.
Ask your dealer for advice and information about
towing a trailer with the vehicle.
The vehicle can tow a trailer if it is equipped with an
automatic transmission and the proper trailer towing
equipment. If the vehicle is not equipped as stated
above, do not tow a trailer. To identify the trailering capacity of the vehicle, read the information in
“Weight
of the Trailer” that appears later in this section.
Trailering is different than just driving the vehicle by
itself. Trailering means changes in handling,
acceleration, braking, cooling, durability and fuel
economy. Successful, safe trailering takes correct
equipment, and it has to be used properly.
The following information has many time-tested,
important trailering tips and safety rules. Many of
these are important for your safety and that of your
passengers. So please read this section carefully
before pulling a trailer.
Load-pulling components such as the engine,
transmission, wheel assemblies and tires are forced to
work harder against the drag of the added weight. The
engine is required to operate at relatively higher speeds
and under greater loads, generating extra heat. Also,
the trailer adds considerably to wind resistance,
increasing the pulling requirements.
