Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{WARNING:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains
Carbon Monoxide (CO) which cannot be seen or
smelled. It can cause unconsciousness and even
death. Never run the engine in an enclosed area
that has no fresh air ventilation. For more
information, seeEngine Exhaust on page 3‑34.
{WARNING:
It can be dangerous to get out of the vehicle if the
automatic transmission shift lever is not fully in
P (Park) with the parking brake firmly set. The
vehicle can roll. Do not leave the vehicle when the
engine is running unless you have to. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on fairly level ground, always set the parking
brake and move the shift lever to P (Park).
Follow the proper steps to be sure the vehicle will not
move. See Shifting Into Park (Automatic Transmission)
on page 3‑31.
If parking on a hill and pulling a trailer, see Towing a
Trailer (Automatic Transmission)
on page 5‑31or
Towing a Trailer (Manual Transmission) on page 5‑37.

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.

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.

reverse directions causes a rocking motion that could
free the vehicle. If that does not get the vehicle out after
a few tries, it might need to be towed out. If the vehicle
does need to be towed out, seeTowing Your Vehicle
on
page 5‑28.
Loading the Vehicle
It is very important to know how much weight your
vehicle can carry. Two labels on your vehicle
show how much weight it may properly carry, the
Tire and Loading Information label and the Vehicle
Certification label.
{WARNING:
Do not load the vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do, parts
on the vehicle can break, and it can change
the way the vehicle handles. These could
cause you to lose control and crash. Also,
overloading can shorten the life of the
vehicle.
Tire and Loading Information Label
Label Example
A vehicle specific Tire and Loading Information
label is attached to the vehicle's center pillar
(B-pillar). With the driver's door open, you will find
the label attached below the door lock post
(striker). The tire and loading information label
lists the number of occupant seating positions (A),
and the maximum vehicle capacity weight (B) in
kilograms and pounds. The vehicle capacity
weight includes the weight of all occupants, cargo,
and all nonfactory‐installed options.
5-22

Black plate (23,1)Chevrolet HHR Owner Manual - 2011
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.

Towing
Towing Your Vehicle
Notice:To avoid damage, the disabled vehicle
should be towed with all four wheels off the ground.
Care must be taken with vehicles that have low
ground clearance and/or special equipment.
Consult your dealer or a professional towing service if
the disabled vehicle must be towed. See Roadside
Assistance Program on page 8‑6.
To tow the vehicle behind another vehicle for
recreational purposes, such as behind a motorhome,
see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing the vehicle
behind another vehicle–such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as dinghy towing and dolly towing.
Dinghy towing is towing the vehicle with all four wheels
on the ground. Dolly towing is towing the vehicle with
two wheels on the ground and two wheels up on a
device known as a dolly. Here are some important things to consider before
recreational vehicle towing:
.What is the towing capacity of the towing vehicle?
Be sure to read the tow vehicle manufacturer's
recommendations.
.What is the distance that will be travelled? Some
vehicles have restrictions on how far and how long
they can tow.
.Is the proper towing equipment going to be used?
See your dealer or trailering professional for
additional advice and equipment
recommendations.
.Is the vehicle ready to be towed? Just as preparing
the vehicle for a long trip, make sure the vehicle is
prepared to be towed. See
Before Leaving on a
Long Trip on page 5‑17.
