WARNING: (Continued)
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
If No Steam Is Coming from the Engine
Compartment
If an engine overheat warning is displayed but no steam
can be seen or heard, the problem may not be too
serious. Sometimes the engine can get a little too hot
when the vehicle:
.Climbs a long hill on a hot day
.Stops after high-speed driving
.Idles for long periods in traffic
.Tows a trailerIf the overheat warning is displayed with no sign of
steam:
1. Turn the air off.
2. Turn the heater on to the highest temperature and to the highest fan speed. Open the windows as
necessary.
3. In heavy traffic, let the engine idle in N (Neutral) while stopped. If it is safe to do so, pull off the
road, shift to P (Park) or N (Neutral) and let the
engine idle.
If the temperature overheat gauge is no longer in the
overheat zone or an overheat warning no longer
displays, the vehicle can be driven. Continue to drive
the vehicle slowly for about 10 minutes. Keep a safe
vehicle distance from the car in front of you. If the
warning does not come back on, continue to drive
normally.
If the warning continues, pull over, stop, and park the
vehicle right away.
If there is no sign of steam, idle the engine for
three minutes while parked. If the warning is still
displayed, turn off the engine until it cools down.

Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to
read the manufacturer's instructions before use. If you
will be operating your vehicle in an area where the
temperature may fall below freezing, use a fluid that has
sufficient protection against freezing.
Adding Washer Fluid
Open the cap with the
washer symbol on it. Add
washer fluid until the tank
is full. SeeEngine
Compartment Overview
on page 6‑14for
reservoir location.
Notice:
.When using concentrated washer fluid,
follow the manufacturer's instructions for
adding water.
.Do not mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage the washer fluid tank and other
parts of the washer system. Also, water does
not clean as well as washer fluid.
.Fill the washer fluid tank only three-quarters
full when it is very cold. This allows for fluid
expansion if freezing occurs, which could
damage the tank if it is completely full.
.Do not use engine coolant (antifreeze) in the
windshield washer. It can damage the
windshield washer system and paint.
Brakes
Brake Fluid
The brake master cylinder and, on manual transmission
vehicles, the clutch hydraulic system use the same
reservoir. See Engine Compartment Overview
on
page 6‑14for the location of the reservoir. The
reservoir is filled with DOT 3 brake fluid.
There are only two reasons why the brake fluid level in
the reservoir might go down:
.The brake fluid level goes down because of
normal brake lining wear. When new linings are
installed, the fluid level goes back up.
.A fluid leak in the brake and/or clutch hydraulic
system can also cause a low fluid level. Have the
brake and/or clutch hydraulic system fixed, since a
leak means that sooner or later the brakes and/or
clutch will not work well.
6-30
Page 307 of 430

Black plate (31,1)Chevrolet HHR Owner Manual - 2011
Do not top off the brake/clutch fluid. Adding fluid does
not correct a leak. If fluid is added when the brake
linings are worn, there will be too much fluid when new
brake linings are installed. Add or remove fluid, as
necessary, only when work is done on the brake/clutch
hydraulic system.
{WARNING:
If too much brake fluid is added, it can spill on the
engine and burn, if the engine is hot enough. You
or others could be burned, and the vehicle could
be damaged. Add brake fluid only when work is
done on the brake and/or clutch hydraulic system.
When the brake fluid falls to a low level, the brake
warning light comes on. See Brake System Warning
Light on page 4‑29.
What to Add
Use only new DOT 3 brake fluid from a sealed
container. See Recommended Fluids and Lubricantson
page 7‑8.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This helps keep dirt
from entering the reservoir.
{WARNING:
With the wrong kind of fluid in the brake or clutch
hydraulic system, the brakes or clutch might not
work well. This could cause a crash. Always use
the proper brake fluid.
Notice:
.Using the wrong fluid can badly damage
brake or clutch hydraulic system parts. For
example, just a few drops of mineral-based
oil, such as engine oil, in the brake or clutch
hydraulic system can damage brake or
clutch hydraulic system parts so badly that
they will have to be replaced. Do not let
someone put in the wrong kind of fluid.
.If brake fluid is spilled on the vehicle's
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on the vehicle. If you do, wash it off
immediately. See Washing Your Vehicle
on
page 6‑95

Brake Wear
This vehicle has front disc brakes and could have rear
drum brakes or rear disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound can come
and go or be heard all the time the vehicle is moving,
except when applying the brake pedal firmly.
{WARNING:
The brake wear warning sound means that soon
the brakes will not work well. That could lead to a
crash. When the brake wear warning sound is
heard, have the vehicle serviced.
Notice: Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates can cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
the brakes. Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to torque specifications in
Capacities and Specifications on page 6‑107.
If the vehicle has rear drum brakes, they do not have
wear indicators, but if a rear brake rubbing noise is
heard, have the rear brake linings inspected
immediately. Rear brake drums should be removed and
inspected each time the tires are removed for rotation or
changing. When the front brake pads are replaced,
have the rear brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign that brake service might be
required.
Brake Adjustment
Every time the brakes are applied, with or without the
vehicle moving, the brakes adjust for wear.

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. The vehicle
was designed and tested with top-quality brake parts.
When parts of the braking system are replaced—for
example, when the brake linings wear down and new
ones are installed —be sure to get new approved
replacement parts. If this is not done, the brakes might
not work properly. For example, if someone puts in
brake linings that are wrong for the vehicle, the balance
between the front and rear brakes can change —for the
worse. The braking performance expected can change
in many other ways if the wrong replacement brake
parts are installed.
Battery
Refer to the replacement number on the original battery
label when a new battery is needed.
The battery is located in the cargo area. Access to the
battery is not necessary to jump start the vehicle. See
Jump Starting on page 6‑34.
{DANGER:
Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals
known to the State of California to cause cancer
and reproductive harm. Wash hands after
handling.
Vehicle Storage
{WARNING:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you are
not careful. See Jump Starting
on page 6‑34for
tips on working around a battery without
getting hurt.
Infrequent Usage: Remove the black, negative (−) cable
from the battery to keep the battery from running down.
Extended Storage: Remove the black, negative (−)
cable from the battery or use a battery trickle charger.

Jump Starting
For more information about the vehicle battery, see
Battery on page 6‑33.
If the vehicle's battery has run down, you may want to
use another vehicle and some jumper cables to start the
vehicle. Be sure to use the following steps to do it
safely.
{WARNING:
Batteries can hurt you. They can be dangerous
because:
.They contain acid that can burn you.
.They contain gas that can explode or ignite.
.They contain enough electricity to burn you.
If you do not follow these steps exactly, some or
all of these things can hurt you.
Notice: Ignoring these steps could result in costly
damage to the vehicle that would not be covered by
the warranty.
Trying to start the vehicle by pushing or pulling it
will not work, and it could damage the vehicle.
1. Check the other vehicle. It must have a 12-volt battery with a negative ground system. Notice:
If the other vehicle's system is not a
12-volt system with a negative ground, both
vehicles can be damaged. Only use vehicles with
12-volt systems with negative grounds to jump start
your vehicle.
2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not
touching each other. If they are, it could cause a
ground connection you do not want. You would not
be able to start the vehicle, and the bad grounding
could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in P (Park) or a manual transmission
in N (Neutral) before setting the parking brake.
Notice: If you leave the radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered by
the warranty. Always turn off the radio and other
accessories when jump starting the vehicle.
3. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged into the
cigarette lighter or the accessory power outlet.
Turn off the radio and all lamps that are not
needed. This will avoid sparks and help save both
batteries. And it could save the radio!

4. Open the hood on the other vehicle and locate thepositive (+) and negative (−) terminal locations on
that vehicle.
You will not see the battery of your vehicle under
the hood. It is located in the rear cargo area. You
will not need to access your battery for jump
starting. The vehicle has a remote positive (+) and
a remote negative (−) jump starting terminal.
Locate the remote
positive terminal which is
located under a red
tethered cap on the
engine compartment fuse
block. Remove the cap to
access the terminal.
Do not remove fuse block cover to jump start the
vehicle.
Locate the remote
negative (−) ground
terminal, marked GND (−),
which is located at the
front of the engine
compartment on the driver
side of the vehicle.
See Engine Compartment Overview
on page 6‑14for more information on the location of the
positive (+) and negative (−) terminals on the
vehicle.
{WARNING:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.

{WARNING:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough water. You do not
need to add water to the battery installed in your
new vehicle. But if a battery has filler caps, be
sure the right amount of fluid is there. If it is low,
add water to take care of that first. If you don't,
explosive gas could be present.
Battery fluid contains acid that can burn you. Do
not get it on you. If you accidentally get it in your
eyes or on your skin, flush the place with water
and get medical help immediately.
{WARNING:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
5. Check that the jumper cables do not have loose or missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if
the vehicle has one. Negative (−) will go to a
heavy, unpainted metal engine part or to a remote
negative (−) terminal if the vehicle has one.
Do not connect positive (+) to negative (−) or you
will get a short that would damage the battery and
maybe other parts too. And do not connect the
negative (−) cable to the negative (−) terminal on
the dead battery because this can cause sparks.
6. Connect the red positive (+) cable to the positive (+) terminal location on the vehicle with the
dead battery. Use a remote positive (+) terminal if
the vehicle has one.
