Retained Accessory Power (RAP)
These vehicle accessories may be used for up to
10 minutes after the engine is turned off.
.Audio System
.Power Windows, if equipped
.Sunroof, if equipped
The power windows and sunroof will continue to work
for up to 10 minutes or until any door is opened. The
radio will work when the key is in ON/RUN or ACC/
ACCESSORY. Once the key is turned from ON/RUN to
OFF/LOCK, the radio will continue to work for
10 minutes or until the driver's door is opened.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move the shift lever to P (Park) or N (Neutral). The
engine will not start in any other position. To restart the
vehicle when it is already moving, use N (Neutral) only.
Notice: Do not try to shift to P (Park) if the vehicle is
moving. If you do, you could damage the
transmission. Shift to P (Park) only when the vehicle
is stopped.
Manual Transmission
The shift lever should be in N (Neutral) and the parking
brake engaged. Hold the clutch pedal down to the floor
and start the engine. The vehicle will not start if the
clutch pedal is not all the way down.
Starting Procedure
1. With your foot off the accelerator pedal, turn the ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as the
engine warms. Do not race the engine immediately
after starting it. Operate the engine and
transmission gently to allow the oil to warm up and
lubricate all moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is
turned to the START position, and then released
when the engine begins cranking, the engine will
continue cranking for a few seconds or until the
vehicle starts. If the engine does not start and the
key is held in START for many seconds, cranking
will be stopped after 15 seconds to prevent
cranking motor damage. To prevent gear damage,
this system also prevents cranking if the engine is
already running. Engine cranking can be stopped
by turning the ignition switch to ACC/ACCESSORY
or LOCK/OFF.
3-24

Black plate (25,1)Chevrolet HHR Owner Manual - 2011
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.
2. If the engine does not start after 5‐10 seconds, especially in very cold weather (below 0°F or
−18°C), it could be flooded with too much gasoline.
Push the accelerator pedal all the way to the floor
and holding it there as you hold the key in START
for a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool. When the engine starts, let go of the
key and accelerator. If the vehicle starts briefly but
then stops again, repeat the procedure. This clears
the extra gasoline from the engine. Do not race the
engine immediately after starting it. Operate the
engine and transmission gently until the oil warms
up and lubricates all moving parts. Notice:
The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical
equipment, check with your dealer. If you do not,
the engine might not perform properly. Any
resulting damage would not be covered by the
vehicle warranty.
Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm‐up in cold
weather condition at or below −18°C (0°F). Vehicles
with an engine coolant heater should be plugged in at
least four hours before starting. An internal thermostat
in the plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures
above −18°C (0°F).

Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
.start the engine,
.shift into a gear, and
.release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling a
trailer. See this manual's Maintenance Schedule or
Index for more information. Things that are especially
important in trailer operation are automatic transmission
fluid, engine oil, axle lubricant, belts, cooling system
and brake system. It is a good idea to inspect these
before and during the trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat during
severe operating conditions. See Engine Overheating
on page 6‑28.
Towing a Trailer (Manual
Transmission)
Do not tow a trailer if the vehicle is equipped with a
manual transmission.

Manual Transmission Fluid
It is not necessary to check the manual transmission
fluid level. A transmission fluid leak is the only reason
for fluid loss. If a leak occurs, take the vehicle to a
dealer for service. Have it repaired as soon as possible.
You may also have the fluid level checked by your
dealer when the oil is changed. SeeRecommended
Fluids and Lubricants
on page 7‑8for the proper fluid
to use.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives fluid from the brake master cylinder
reservoir.
See Brakes
on page 6‑30for more information.
Cooling System
The cooling system allows the engine to maintain the
correct working temperature.
