2008 Chevrolet HHR Owner ManualM

{CAUTION:
If you have a manual transmission 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/ACCESSORY.
ACC (ACC/ACCESSORY):This position operates
some of your electrical accessories. It unlocks the
steering wheel and ignition.
R(ON/RUN):This is the position the switch returns to
after you start your engine and release the switch.
The switch stays in the ON/RUN position when
the engine is running. But even when the ignition is not
running, you can use ON/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/ACCESSORY or ON/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 ON/RUN for normal driving.
A warning tone will sound if you open the driver’s door
while in LOCK/OFF or ACC/ACCESSORY, 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 transmission.
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.

Parking Brake
The parking brake lever is located between the front
seats.
{CAUTION:
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, your 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.
SeeBrake System Warning Light on page 3-35.

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.
2-33

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.

Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers are turned on. For this
feature to work, automatic lighting must be enabled. See
Headlamps on page 3-15for additional information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They will also turn
off 15 seconds after the windshield wiper control is
turned off.
Headlamps on Reminder
If the driver’s door is opened with the ignition off and
the lamps on, a warning chime will sound. This lets you
know that the headlamps are still on.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.Your vehicle has a light sensor on top of the instrument
panel. Make sure it is not covered or the headlamps
will come on when you do not need them.
The DRL system will make the headlamps come on at
reduced brightness when the following conditions
are met:
The ignition is on.
The exterior lamp control is turned to AUTO.
The light sensor detects daytime light.
The shift lever is not in PARK (P).
While the DRL system is on, the taillamps, sidemarker
lamps, and instrument panel lights will not be
illuminated.
The DRL system will be off any time your vehicle is in
PARK (P). The DRL system on U.S. vehicles can
also be turned off by using the off/on switch for one
ignition cycle.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
