2005 BUICK CENTURY wheel

Make sure the shift lever is fully in PARK (P) before
starting the engine. The vehicle has an automatic
transaxle shift lock control system. The regular brakes
must be fully applied before shifting from PARK (P)
when the ignition is in RUN. If the vehicle cannot
be shifted out of PARK (P), increase pressure on the
shift lever by pushing it all the way into PARK (P) while
keeping the brake pedal pushed down. Then move
the shift lever out of PARK (P). SeeShifting Out of
Park (P) on page 2-26.
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.
REVERSE (R): Use this gear to back up.
To rock the vehicle back and forth in order to get it out
of snow, ice, or sand without damaging the transaxle,
seeIf You Are Stuck: In Sand, Mud, Ice or Snow
on page 4-30.
NEUTRAL (N): In this position, the engine does not
connect with the wheels. To restart when the vehicle is
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when the 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)
with the engine racing may damage the transaxle.
The repairs would not be covered by your warranty.
Be sure the engine is not racing when shifting
your vehicle.
Notice:Driving your vehicle if you notice that it is
moving slowly or not shifting gears as you
increase speed may damage the transaxle. Have
your vehicle serviced right away. You can drive in
SECOND (2) when you are driving less than 35 mph
(55 km/h) and AUTOMATIC OVERDRIVE (D) for
higher speeds until then.

Hazard Warning Flashers
Your hazard warning ashers let you warn others. They
also let police know you have a problem. Your front
and rear turn signal lamps will ash on and off.
The hazard warning asher
button is located on top of
the steering column.
Your hazard warning ashers work no matter what
position your key is in, and even if the key is not in.
Press the button to make the front and rear turn signal
lamps ash on and off. Press the button again to
turn the ashers off.
When the hazard warning ashers are on, your turn
signals will not work.
Other Warning Devices
If you carry reective triangles, you can set one up at
the side of the road about 300 feet (100 m) behind
your vehicle.
Horn
Press near or on the horn symbols on your steering
wheel pad to sound the horn.
Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. You can raise the steering wheel to
the highest level to give your legs more room when you
enter and exit the vehicle.
The lever that allows you to tilt the steering wheel is
located on the left side of the steering column.
To tilt the wheel, hold the
wheel and pull the lever.
Then move the wheel
to a comfortable position
and release the lever
to lock the wheel in place.

Cruise Control
If the vehicle has cruise control, a speed of about
25 mph (40 km/h) or more can be maintained without
keeping your foot on the accelerator. This can really help
on long trips. Cruise control does not work at speeds
below about 25 mph (40 km/h).
When the brakes are applied, the cruise control shuts off.
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause needless wheel spinning,
and you could lose control. Do not use cruise
control on slippery roads.The cruise control will automatically disengage when the
enhanced traction system begins to limit wheel spin.
SeeEnhanced Traction System (ETS) on page 4-9.
When road conditions allow, the cruise control can be
used again.
Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.

Enhanced Traction System
Warning Light
If the vehicle has the
Enhanced Traction
System, (ETS) the warning
light may come on for
the following reasons:
When the vehicle is shifted to SECOND (2) or
FIRST (1). To turn the system back on, shift
to THIRD (3) or AUTOMATIC OVERDRIVE (
X).
SeeEnhanced Traction System (ETS) on page 4-9.
If the vehicle needs service. Adjust your
driving accordingly.
When the parking brake is set with the engine
running, and the parking brake does not release fully.
After the parking brake is fully released and the
transaxle shift lever is in any position other than
FIRST (1) or SECOND (2). This means there is a
problem with the system.
If an engine-related problem affects the ETS and
turns the system off.
When the ETS warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
Low Traction Light
If the vehicle has the
Enhanced Traction System
(ETS), this light will
come on when the system
is limiting wheel spin.
You may feel or hear the system working, but this is
normal. Slippery road conditions may exist if the
low traction light comes on, so adjust your driving
accordingly. The light will stay on for a few seconds after
the ETS stops limiting wheel spin. SeeEnhanced
Traction System (ETS) on page 4-9.
The low traction light also comes on briey when the
ignition key is turned to RUN. If the light does not come
on then, have it xed so it will function properly to
indicate when the Enhanced Traction System is active.

Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
vehicle’s radio. It works by using a secret code to
disable all radio functions whenever battery power is
removed and the radio is placed in a different vehicle.
This feature requires no user input to be activated.
The radio is automatically armed when it is put into the
vehicle for the rst time.
When the ignition is turned off, the blinking red light
indicates that THEFTLOCK
®is armed.
If THEFTLOCK
®is activated, the radio will not operate
if stolen. The radio will display LOCKED and a red
LED indicator light will come on above the key symbol
to indicate a locked condition. If this occurs, the radio will
need to be returned to your GM dealer.
Audio Steering Wheel Controls
If your vehicle has this feature, some audio functions
can be adjusted at the steering wheel. They include
the following:
QSEEKR:Press the up or the down arrow to go to
the next or to the previous radio station. The radio
will only seek stations with a strong signal that are in
the selected band.
When a cassette tape or CD is playing, press the
up or the down arrow to go to the next or the
previous selection.
