2007 CHEVROLET HHR engine

Ignition Positions
With the key in the ignition switch, you can turn it
to four different positions.
Notice:Using a tool to force the key from the
ignition switch could cause damage or
break the key. Use the correct key and turn the
key only with your hand. Make sure the key
is all the way in. If it is, turn the steering wheel
left and right while you turn the key hard. If
none of this works, then your vehicle needs
service.
9(LOCK):This position locks your steering
column. It is a theft-deterrent feature. You will only
be able to remove your key when the ignition is
turned to LOCK.
If you have an automatic transaxle, the ignition
switch cannot be turned to LOCK unless the shift
lever is in PARK (P).
If you have a manual transaxle, the ignition switch
can be turned to LOCK in any shift lever position.
{CAUTION:
If you have a manual transaxle removing
the key from the ignition switch will lock
the steering column and result in a loss of
ability to steer the vehicle. This could
cause a collision. If you need to turn the
engine off while the vehicle is moving,
turn the key to ACC.
ACC (ACCESSORY):This position operates
some of your electrical accessories. It unlocks the
steering wheel and ignition.
116

R(RUN):This is the position the switch returns to
after you start your engine and release the
switch. The switch stays in the RUN position when
the engine is running. But even when the ignition
is not running, you can use RUN to operate
your electrical accessories and to display some
warning and indicator lights.
The battery could be drained if you leave the key
in the ACC or RUN position with the engine
off. You may not be able to start your vehicle if
the battery is allowed to drain for an extended
period of time.
/(START):This position starts the engine.
When the engine starts, release the key.
The ignition switch will return to RUN for normal
driving.
A warning tone will sound if you open the driver’s
door while in LOCK or ACC, when the key has
not been removed from the ignition.
Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your
vehicle,a chime will sound, when you open the
driver’s door. Always remember to remove
your key from the ignition and take it with you.
This will lock your ignition and transaxle.
Also, always remember to lock the doors.
The battery could be drained if you leave the key
in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it
has been parked for an extended period of time.
117

Retained Accessory Power (RAP)
Your vehicle has a Retained Accessory
Power (RAP) feature which allow’s the radio,
power windows, and sunroof to continue to work
up to 10 minutes after the ignition is turned off.
Your vehicle’s radio will work when the ignition key
is in RUN or ACC. Once the key is turned from
RUN to LOCK, the radio will continue to work for
10 minutes or until the driver’s door is opened.
Also, the power windows and sunroof will continue
to work for up to 10 minutes or until any door is
opened.
Starting the Engine
Place the transaxle in the proper gear.
Automatic Transaxle
Move your shift lever to PARK (P) or
NEUTRAL (N). Your 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:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
Manual Transaxle
The shift lever should be in the neutral position
and the parking brake engaged. Hold the
clutch pedal 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.
119

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 transaxle 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 the ACC or LOCK position.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 allow
the cranking motor to 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 transaxle gently until the
oil warms up and lubricates all moving parts.
120

Notice:Your 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. 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
If your vehicle has this feature, in very cold
weather 0°F (−18°C) or colder, the engine coolant
heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged
in a minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
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.
121

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 GM
dealer in the area where you will be parking your
vehicle. The dealer can give you the best
advice for that particular area.
Automatic Transaxle Operation
If your vehicle has an automatic transaxle, the
shift lever is located on the console between the
seats.There are several
different positions for
the automatic transaxle.
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.
122

{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
Transaxle) on page 128. If you are pulling
a trailer, seeTowing a Trailer (Manual
Transaxle) on page 276orTowing a
Trailer (Automatic Transaxle) on page 277.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 Transaxle) on page 130.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage the
transaxle. 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
transaxle, seeIf Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 268.
123

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 your
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) while the engine is running at
high speed may damage the transaxle.
The repairs would not be covered by your
warranty. Be sure the engine is not running at
high speeds when shifting your vehicle.
DRIVE (D):This position is for normal driving with
the automatic transaxle. It provides the best fuel
economy for your vehicle. If you need more power
for passing, and you are:
Going less than about 35 mph (55 km/h), push
your accelerator pedal about halfway down.
Going about 35 mph (55 km/h), push
your accelerator all the way down.
Downshifting the transaxle in slippery road
conditions could result in skidding, see “Skidding”
underLoss of Control on page 253.
