2008 CHEVROLET HHR engine

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
Sunroof
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 PARK (P) or NEUTRAL (N). The
engine will not start in any other position -- this is a
safety feature. To restart when you are already moving,
use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transmission
The shift lever should be in neutral position and the
parking brake engaged. Hold the clutch pedal down to
the oor and start the engine. Your vehicle will not
start if the clutch pedal is not all the way down. That is
a safety feature.

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
your engine gets warm. 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.
Your 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.
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 ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
and holding it there as you hold the key in START for
up to a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool down. When the engine starts, let go of
the key and accelerator. If the vehicle starts briey
but then stops again, do the same thing. 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 your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, your
engine might not perform properly. Any resulting
damage would not be covered by your vehicle’s
warranty.

Engine Coolant Heater
The engine coolant heater, if available, can help in cold
weather conditions at or below 0°F (−18°C) for easier
starting and better fuel economy during engine warm-up.
Plug in the coolant heater at least four hours before
starting your vehicle. An internal thermostat in the
plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures
above 0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. For
the 2.2L and 2.4L engine, the electrical cord is
located on the passenger’s side of the vehicle near
the headlamp and the radiator.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
a dealer/retailer in the area where you will be parking
your vehicle. The dealer/retailer can give you the
best advice for that particular area.

Automatic Transmission Operation
If your vehicle has an automatic transmission, the
shift lever is located on the console between the seats.
There are several different
positions for the automatic
transmission.
PARK (P):This position locks your front wheels. It is
the best position to use when you start your engine
because your vehicle cannot move easily.{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your 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 your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). SeeShifting Into PARK (P)
(Automatic Transmission) on page 2-34.Ifyou
are pulling a trailer, seeTowing a Trailer
(Manual Transaxle) on page 4-34orTowing a
Trailer (Automatic Transaxle) on page 4-34.
2-28

Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transaxle shift lock control system. You have to fully
apply your regular brakes rst and then press the shift
lever button before you can shift from PARK (P)
when the ignition key is in RUN. If you cannot shift out
of PARK (P), ease pressure on the shift lever and
push the shift lever all the way into PARK (P) as you
maintain brake application. Then press the shift
lever button and then move the shift lever into another
gear. SeeShifting Out of PARK (P) (Automatic
Transmission) on page 2-36.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice, or sand without damaging your transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-26.NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speed when shifting your vehicle.
2-29

Manual Transmission Operation
This is the shift pattern.
Here is how to operate the manual transmission:
FIRST (1):Press the clutch pedal down and shift into
FIRST (1). Then, slowly let up on the clutch pedal down
as you press the accelerator pedal down.You can shift into FIRST (1) when you are going less
than 20 mph (32 km/h). If you have come to a complete
stop and it is hard to shift into FIRST (1), put the shift
lever in NEUTRAL and let up on the clutch pedal. Press
the clutch pedal back down. Then shift into FIRST (1).
SECOND (2):Press the clutch pedal down as you let up
on the accelerator pedal and shift into SECOND (2).
Then, slowly let up on the clutch pedal as you press the
accelerator pedal.
THIRD (3), FOURTH (4) and FIFTH (5):Shift into
THIRD (3), FOURTH (4) and FIFTH (5) the same way
you do for SECOND (2). Slowly let up on the clutch
pedal as you press the accelerator pedal down.
To stop, let up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press
the clutch pedal down and the brake pedal, and shift to
NEUTRAL.
NEUTRAL:Use this position when you start or idle
your engine.
2-31

If you forget to release your parking brake, a chime will
sound and a warning message will be displayed
when the parking brake is applied and the vehicle is
moving faster than 5 mph (8 kph). SeeDIC Warnings
and Messages on page 3-48.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
Shifting Into PARK (P) (Automatic
Transmission)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly.
CAUTION: (Continued)
CAUTION: (Continued)
You or others could be injured. To be sure
your vehicle will not move, even when you are
on fairly level ground, use the steps that
follow. If you are pulling a trailer, seeTowing a
Trailer (Manual Transaxle) on page 4-34or
Towing a Trailer (Automatic Transaxle) on
page 4-34.
To shift into PARK (P), do the following:
1. Hold the brake pedal down with your right foot and
set the parking brake. SeeParking Brake on
page 2-33for more information.
2. Move the shift lever into PARK (P) by holding in the
button on the shift lever and pushing the lever all
the way toward the front of the vehicle.
3. Turn the ignition key to LOCK/OFF.
4. Remove the key and take it with you. If you can
leave your vehicle with the key in your hand, your
vehicle is in PARK (P).
2-34

Leaving Your Vehicle With the Engine
Running (Automatic Transmission)
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your automatic transmission vehicle
with the engine running, be sure your vehicle is in
PARK (P) and your parking brake is rmly set before
you leave it. After you have moved the shift lever
into PARK (P), hold the regular brake pedal down. Then,
see if you can move the shift lever away from PARK (P)
without rst pulling it toward you. If you can, it means
that the shift lever was not fully locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift into
PARK (P) properly, the weight of the vehicle may put too
much force on the parking pawl in the transmission.
You may nd it difficult to pull the shift lever out of
PARK (P). This is called “torque lock.” To prevent torque
lock, set the parking brake and then shift into PARK (P)
properly before you leave the driver’s seat. To nd
out how, seeShifting Into PARK (P) (Automatic
Transmission) on page 2-34.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).
