2005 CHEVROLET COBALT parking brake

Torque Lock
If you are parking on a hill and you do not shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. 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 Transaxle) on page 2-28.
When you are ready to drive, move the shift lever out of
PARK (P)beforeyou 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 transaxle, so you
can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
(Automatic Transaxle)
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 PARK (P) with the shift lever button fully
released, and
prevent movement of the shift lever out of PARK (P)
unless the ignition is in a position other than LOCK.The shift lock release is always functional except in the
case of a an uncharged or low voltage (less than 9 volt)
battery.
If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. SeeJump Starting on page 5-40for more
information.
If you still cannot move the shift lever from PARK (P),
consult your dealer or a professional towing service.
Parking Your Vehicle
Before leaving your vehicle, fully press the clutch pedal
in, move the shift lever into REVERSE (R), and rmly
apply the parking brake. Once the shift lever has
been placed in REVERSE (R) with the clutch pedal
pressed in, you can turn the ignition key to LOCK,
remove the key and release the clutch. SeeManual
Transaxle Operation on page 2-24.

Running the Engine While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-30.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-25.
{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. 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).
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) (Automatic Transaxle)
on page 2-28.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer (Manual Transaxle) on
page 4-37orTowing a Trailer (Automatic Transaxle)
on page 4-38.

Ending Cruise Control
To end cruise control, step lightly on the brake pedal or
the clutch if your vehicle has a manual transmission.
Stepping on the brake pedal or clutch will only end the
current cruise control session. Press the cruise
control on/off button to turn the system completely off.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Headlamps
The lever on the left side of the steering column
operates the exterior lamps.The exterior lamp switch has the following four positions:
2(Headlamps):This position turns on the
headlamps, parking lamps, and taillamps.
;(Parking Lamps):This position turns on the
parking lamps and taillamps only.
AUTO (Automatic Headlamp System):This position
automatically turns on the Daytime Running Lamps
during daytime, and the headlamps, parking lamps, and
taillamps at night.
P(Off/On):This position is the momentary Off/On
switch for the Automatic Headlamp System. In Canada,
this only works when the vehicles with an automatic
transmission are in PARK (P) and vehicles with a
manual transmission have the parking brake set.
When operating in AUTO, a momentary turn of the
switch to off/on will turn off the Automatic Headlamp
System. An AUTO LIGHTS OFF message will display on
the driver information center and a chime will sound.
Rotating the switch to off/on again will turn the Automatic
Headlamp System back on. An AUTO LIGHTS ON
message will display on the driver information center.
3-13

The Automatic Headlamp System is always turned on at
the beginning of an ignition cycle for vehicles with
manual transmission. When the parking brake is on, the
automatic headlamps will turn off. For vehicles with
automatic transmission, when the gear is shifted out of
PARK, the Automatic Headlamp System will turn on.
Shifting the gear back to PARK (P) will turn off the
automatic headlamp system for vehicles with an
automatic transmission.
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 3-13for 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 you open the driver’s door with the ignition off and the
lamps on, you will hear a warning chime.
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 both front turn signal lamps
turn on 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.
