2010 CHEVROLET HHR Owners Manual

Up-Shift Light
If the vehicle has a
manual transmission,
there may be an up-shift
light. This light will show
you when to shift to the
next higher gear for the
best fuel economy.
When this light comes on, you can shift to the next
higher gear if weather, road, and traffic conditions let
you. For the best fuel economy, accelerate slowly and
shift when the light comes on.
While accelerating, it is normal for the light to go on and
off if you quickly change the position of the accelerator.
Ignore the light when downshifting.
No‐Lift Upshift (SS Models)
If the vehicle has the 2.0L turbo engine and manual
transmission, it has the capability of No-Lift Upshifts.
This feature maximizes vehicle acceleration by allowing
you to shift the transmission to a higher gear without
taking your foot off the accelerator. No‐Lift Upshifting is
enabled in all Electronic Stability Control modes. See
Electronic Stability Control (ESC)
on page 5‑6for
more information. Use this feature only when the engine
has reached normal operating temperature. Correct
shifting allows the engine to maintain boost pressure
during shifts, while also keeping the engine from
over-revving.
3-33

To utilize this feature:1. Accelerate the vehicle by fully depressing the accelerator pedal.
2. Just prior to reaching the maximum engine speed, quickly complete the upshift utilizing the clutch
while keeping the accelerator pedal fully applied.
A quicker shift maneuver gives the best
performance. If the engine is operated at the
maximum engine speed for greater than
one second, the engine exits the No‐Lift Upshift
mode and resumes normal engine overspeed
protection.Parking Brake
The parking brake lever is located between the front
seats.
3-34

{WARNING:
If the front passenger seat back is folded down,
the armrest may make it awkward to grab and
pull up the parking brake lever. If the lever is not
pulled up far enough, the vehicle may roll and you
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 4‑30. 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 4‑48.
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.
3-35

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, seeTowing a Trailer
(Automatic Transmission)
on page 5‑32or
Towing a Trailer (Manual Transmission)
on
page 5‑40
.
To shift into P (Park): 1. Hold the brake pedal down and set the parking brake. See Parking Brake
on page 3‑34for more
information.
2. Move the shift lever into P (Park) 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.
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).
3-36

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 3‑36.
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).
Shifting Out of Park
(Automatic Transmission)
This vehicle is equipped with an electronic shift lock
release system. The shift lock release is designed to:
.Prevent ignition key removal unless the shift lever
is in P (Park) with the shift lever button fully
released, and
.Prevent movement of the shift lever out of
P (Park) unless the ignition is in ON/RUN or
ACC/ACCESSORY and the regular brake pedal
is applied.
The shift lock release is always functional except in the
case of a an uncharged or low voltage (less than 9 volt)
battery.
3-37

If the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
SeeJump Starting
on page 6‑41for more information.
To shift out of P (Park): 1. Apply the brake pedal.
2. Then press the shift lever button.
3. Move the shift lever to the desired position.
If you still are unable to shift out of P (Park): 1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift lever button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from P (Park),
consult your dealer/retailer or a professional towing
service.
Parking the Vehicle
(Manual Transmission)
Before leaving the vehicle, fully press the clutch pedal
down, move the shift lever into R (Reverse), and firmly
apply the parking brake. Once the shift lever has been
placed in R (Reverse) with the clutch pedal pressed
down, the ignition key can be turned to LOCK/OFF, then
remove the key and release the clutch pedal. See
Manual Transmission Operation on page 3‑31.

Things that can burn could touch hot exhaust
parts under the vehicle and ignite. Do not park
over papers, leaves, dry grass, or other things that
can burn.
3-38

Engine Exhaust
{WARNING:
Engine exhaust contains Carbon Monoxide (CO)
which cannot be seen or smelled. Exposure to CO
can cause unconsciousness and even death.
Exhaust may enter the vehicle if:
.The vehicle idles in areas with poor ventilation
(parking garages, tunnels, deep snow that
may block underbody airflow or tail pipes).
.The exhaust smells or sounds strange or
different.
.The exhaust system leaks due to corrosion or
damage.
.The vehicle’s exhaust system has been
modified, damaged or improperly repaired.
.There are holes or openings in the vehicle
body from damage or after-market
modifications that are not completely sealed.(Continued)

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
