To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. Theelectrical cord is located on the passenger side of
the vehicle near the headlamp and the radiator.
3. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
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, to prevent damage.
The length of time the heater should remain plugged in
depends on several factors. Ask a dealer in the area
where you will be parking the vehicle for the best advice
on this.
Automatic Transmission Operation
If the 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.
P (Park): This position locks the front wheels. It is the
best position to use when starting the engine because
the vehicle cannot move easily.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.

WARNING: (Continued)
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). SeeShifting Into
Park (Automatic Transmission)
on page 3‑31.
If you are pulling a trailer, see Towing a Trailer
(Automatic Transmission)
on page 5‑31or
Towing a Trailer (Manual Transmission)
on
page 5‑37
.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You have to fully
apply the regular brakes first and then press the shift
lever button before the vehicle can shift from P (Park)
when the ignition key is in ON/RUN. If the vehicle
cannot shift out of P (Park), ease pressure on the shift
lever and push the shift lever all the way into P (Park)
as you maintain brake application. Then press the shift
lever button and then move the shift lever into another
gear. See Shifting Out of Park (Automatic Transmission)
on page 3‑33. R (Reverse):
Use this gear to back up.
Notice: Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock your vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission, see If
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on
page 5‑21.
N (Neutral): In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. Also,
use N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
3-27

Black plate (28,1)Chevrolet HHR Owner Manual - 2011
Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage the
transmission. The repairs would not be covered by
the vehicle warranty. Be sure the engine is not
running at high speed when shifting the vehicle.
D (Drive): This position is for normal driving with the
automatic transmission. It provides the best fuel
economy. If you need more power for passing and
you are:
.Going less than about 55 km/h (35 mph), push the
accelerator pedal about halfway down.
.Going about 55 km/h (35 mph), push the
accelerator all the way down.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”under
Loss of Control on page 5‑14.
I (Intermediate): This position is also used for normal
driving. However, it reduces vehicle speed without using
the brakes for slight downgrades where the vehicle
would otherwise accelerate due to steepness of grade.
If constant upshifting or downshifting occurs while
driving up steep hills, this position can be used to
prevent repetitive types of shifts. You might choose
I (Intermediate) instead of D (Drive) when driving on
hilly, winding roads and when towing a trailer, so that
there is less shifting between gears. PERFORMANCE SHIFTING:
If the vehicle has this
feature, it can detect a change in driving patterns while
in the Intermediate position. If you make an aggressive
driving maneuver, the vehicle's transmission
automatically shifts to the lowest possible gear to
maximize vehicle performance. The vehicle will
automatically return to normal operation when you
return to normal driving patterns.
L (Low): This position reduces vehicle speed more than
I (Intermediate) without actually using the brakes. You
can use it on very steep hills, or in deep snow or mud.
If the shift lever is put in L (Low), the transmission will
not shift into L (Low) until the vehicle is going slowly
enough.
Notice: Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator pedal
may damage the transmission. The repair will not be
covered by the vehicle warranty. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.

WARNING: (Continued)
or others could be injured. Move your hand lower
on the lever or raise the seat back so that you can
set the brake.
To set the parking brake, hold the brake pedal down
and pull up on the parking brake lever. If the ignition is
on, the brake system warning light will come on. See
Brake System Warning Light on page 4‑29.
To release the parking brake, hold the brake pedal
down. Pull the parking brake lever up until you can
press the release button. Hold the release button in as
you move the brake lever all the way down.
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 km/h). See DIC Warnings and
Messages on page 4‑40.
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. 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.
Shifting Into Park (Automatic
Transmission)
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll. 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, use the steps that follow.
If you are pulling a trailer, see Towing a Trailer
(Automatic Transmission)
on page 5‑31or
Towing a Trailer (Manual Transmission)
on
page 5‑37
.
To shift into P (Park): 1. Hold the brake pedal down and set the parking brake. See Parking Brake
on page 3‑30for more
information.
3-31

2. Move the shift lever into P (Park) by holding in thebutton 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.
Leaving the Vehicle With the Engine
Running (Automatic Transmission)
{WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) with the
parking brake firmly set. And, if you leave the
vehicle with the engine running, it could overheat
and even catch fire. You or others could be
injured. Do not leave the vehicle with the engine
running.
If you have to leave an automatic transmission vehicle
with the engine running, be sure the vehicle is in
P (Park) and the parking brake is firmly set before you
leave it. After you have moved the shift lever into
P (Park), hold the brake pedal down. Then, see if you
can move the shift lever away from P (Park) without first
pushing the button. If you can, it means that the shift
lever was not fully locked into P (Park).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift into
P (Park) properly, the weight of the vehicle may put too
much force on the parking pawl in the transmission. You
may find it difficult to pull the shift lever out of P (Park).
This is called “torque lock.” To prevent torque lock, set
the parking brake and then shift into P (Park) properly
before you leave the driver seat. To find out how, see
Shifting Into Park (Automatic Transmission)
on
page 3‑31.
Move the shift lever out of P (Park) 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 P (Park).

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).
