Torque Lock
If you are parking on a hill and you don’t 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 find 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 find out how, see “Shifting Into PARK (P)” in
the Index.
When you are ready to drive, move the shift lever out
of
PARK (P) 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 transaxle,
so you
can pull the shift lever out of PARK (P).
Shifting Out of PARK (P)
Your Buick has a brake-transaxle shift interlock. You
must fully apply your regular brakes before you can
shift from PARK (P) when the ignition is in RUN. See
“Automatic Transaxle Operation” in the Index.
If
you cannot shift out of PARK (P), ease 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).
If
you ever hold the brake pedal down but still can’t
shift
out of PARK (P), try this:
1. Turn the key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the engine and shift to the drive gear you want.
5. Have the vehicle fixed as soon as you can.

Running Your Engine While
You’re Parked
It’s better not to park with the engine running. But if you
ever have to, here are some things to know.
Idling the engine with the climate control system
off could allow dangerous exhaust into your
vehicle (see the earlier Caution under
“Engine Exhaust”).
Also, idling in
a closed-in place can let deadly
carbon monoxide
(CO) into your vehicle even if
the fan switch 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
“Blizzard” in the Index.)
A 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 firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine is
running unless you have
to. If you’ve left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won’t move, even when you’re 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 won’t
move. See “Shifting Into
PARK (P)” in the Index.
If you are parking on a hill and if you’re pulling a
trailer, also see “Towing a Trailer” in the Index.

Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This,
of course, shuts off
the cruise control.
But you don’t need to reset it.
Once you’re going about
25 mph (40 km/h) or more,
you can move the cruise
control switch from
ON to
R/A (Resume/Accelerate)
for about half
a second.
You’ll
go right back up to
your chosen speed and
stay there.
Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher speed,
Push in the SETKOAST button, then release the
button and
the accelerator pedal. You’ll now cruise at
the higher speed.
Move the cruise switch from ON to R/A. Hold it
there until you get up
to the speed you want, and
then release the switch. (To increase your speed in
very small amounts, move the switch to R/A for less
than half
a second and then release it. Each time
you do
this, your vehicle will go about 1 mph
( 1.6 kmk) faster.)
The accelerate feature will only work after you set
the cruise control speed by pushing the
SETKOAST button.

lower speed
you want, then release
it.
Passing Another Vehicle While Using Cruise Control
Use the accelerator pedal to increase your speed. When
you take your foot off the pedal, your vehicle will slow
down to
the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness
of the hills.
When going up steep hills, you may have to step on the
accelerator pedal to maintain your speed. When going downhill,
you may
have to brake or shift to a lower gear
to keep your speed down. Of course, applying the brake
takes you
out of cruise control. Many drivers find this to
be too much trouble and don’t use cruise control on
steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
Step lightly on the brake pedal; OR
0 Move the cruise switch to OFF.
Erasing Cruise Speed Memory
When you turn off the cruise control or the ignition, or
shift into PARK
(P) or NEUTRAL (N), your cruise
control
set speed memory is erased.

Daytime Running Lamps / Automatic
Headlamp Control
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.
A light sensor on top of the instrument panel makes the
DRL work,
so be sure it isn’t covered.
The DRL system
will make your front turn signal lamps
come on when:
0 The ignition is on,
The headlamp switch is off and
0 The parking brake is released.
When the DRL are on, only your your front turn signal
lamps will be on. The headlamps, taillamps, sidemarker
and other lamps won’t be
on. Your instrument panel
won’t be lit up either. When it’s
dark enough outside, your front turn signal
lamps will turn off and your vehicle’s headlamps and
parklamps will turn on. The other lamps that come on
with your headlamps will also come on.
When it’s bright enough outside, your headlamps will go
off and your front turn signal lamps will come on.
To idle your vehicle with the DRL off, set the parking
brake while the ignition is in
OFF or LOCK. Then start
your vehicle. The DRL, headlamps and parklamps will
stay off
until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need
it.

The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN.
If the
light doesn’t come
on then, have it fixed so it will be
ready to warn you if there is
a problem.
Charging System Light

The charging system light
will come on briefly when
you turn
on the ignition, as
a check to show
you it’s
working. Then it should
go out.
If it stays on, or comes on while you are driving, you
may have a problem with the charging system. It could
indicate that you have a loose drive belt or another
electrical problem. Have it checked right away. Driving
while this light is on could drain your battery.
If you must drive a short distance with the light on, be
certain
to turn off all your accessories, such as the radio
and air conditioner.
Brake System Warning Light
Your Buick’s hydraulic brake system is divided into two
parts. If
one part isn’t working, the other part can still
work and stop you. For good braking, though, you need
both parts working well.
If the warning light comes on, there could be
a brake
problem. Have your brake system inspected right away.
BRAKE
This light should come
on briefly when you turn
the ignition key
to RUN.
If it doesn’t come
on then,
have it fixed
so it will be
ready to warn
you if there’s
a problem.
If the light comes
on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still
on, or if the
anti-lock brake system warning light is flashing, have
the vehicle towed for service. (See “Anti-Lock Brake
System Warning Light” and “Towing Your Vehicle” in
the Index.)

Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident.
If the light is still on or if the
anti-lock brake system warning light is flashing

off the road and stopped
carefully, have the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay
on if your parking brake doesn’t release
fully. If it stays on after your parking brake is
fully
released, it means you have a brake problem.
Anti-Lock Brake System Warning Light

LOCK
With the anti-lock brake
system, this light will come
on when
you start your

anti-lock brakes and there could be
a problem with your
regular brakes. Pull off the road and stop carefully.

may notice that the pedal is harder to push. Or, the pedal
may
go closer to the floor. It may take longer to stop.
