ignition BUICK PARK AVENUE 1997 Repair Manual

3. Turn off the ignition on both vehicles. Turn off the
radios and all lamps that aren’t needed. This will
avoid
sparks and help save both batteries. It could
save your radio
!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. Open the hoods and locate the batteries.
A CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
5. Find the positive (+) and negative (-) terminals on
each battery.
A CAUTION:
Using a match near a battery can cause battery
gas to explode, People have been hurt doing this,
and some have been blinded, Use a flashlight if
you need more light.
Be sure the battery has enough water. You don’t
need
to add water to the Delco Freedom@ battery
installed in every new
GM vehicle. But if a
battery has filler caps, be sure the right amount
of fluid is there.
If it is low, add water to take care
of
that first. If you don’t, explosive gas could
be present.
’ Battery fluid contains acid that can burn you.
Don’t get
it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.

A vehicle can fall from a car carrier if it isn’t
adequately secured. This can cause a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks. They will damage drivetrain and
suspension components.
When your vehicle is being towed, have the ignition
key in the
OFF position. The steering wheel should be
clamped in a straight-ahead position, with a clamping
device designed for towing service.
Do not use the
vehicle’s steering column lock for this. The transaxle
should
be in NEUTRAL (N) and the parking
brake released.
Don’t have your vehicle towed on the front wheels,
unless you must.
If the vehicle must be towed on the
front wheels, be sure to follow the speed and distance
restrictions later in
this section .or your transaxle will be
damaged.
If these limits must be exceeded, then the
front wheels have to be supported on a dolly.

To reset (calibrate) the system:
1. Turn the ignition switch to RUN.
2. Press the GAGES button on the DIC until TIRE
PRESSURE appears on the display.
3. Press and hold the DIC RESET button for about
five seconds. After five seconds, the display will
show TIRE PRESSURE RESET. If
TIRE
PRESSURE RESET does not appear on the display
after about five seconds, see your dealer for service.
After you release the DIC RESET button, TIRE
PRESSURE NORMAL will appear on the display.
The system completes the calibration process during
driving. During the first
10 to 20 miles (15 to 30 km) of
driving, the system will not alert you if
a tire is high or
low. After
20 to 80 miles (30 to 125 km), the system
will only alert you about pressure differences of
12 psi
(85 kPa) or more. After about 80 miles (125 km) of
driving, the system will alert you if one tire is
10 psi
(69 kPa) different from the other three tires.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual wear,
rotate your tires
as soon as possible and check wheel
alignment. Also check for damaged tires or wheels. See
“When It’s Time for New Tires” and “Wheel
Replacement’’ later in
this section for more information.
The purpose of regular rotation is to achieve more uniform
wear for
all tires on the vehicle. The fist rotation is the
most important. See “Scheduled Maintenance Services” in
the Index for scheduled rotation intervals.

Ignition Transaxle Lock Check
While parked, and with the parking brake set, try to turn
the ignition key to LOCK in each shift lever position.
The key should turn to LOCK only when the shift
lever is
in PARK (P).
The key should come out only in LOCK.
Parking Brake and Automatic Transaxle PARK (P)
Mechanism Check
When you are doing this check, your vehicle
could begin to move. You or others could be
injured and property could be damaged. Make
sure there
is room in front of your vehicle in case
it begins to roll. Be ready to apply the regular
brake
at once should the vehicle begin to move. Park on a fairly
steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake, set the
parking brake.
To check the parking brake’s holding ability: With
the engine running and transaxle in NEUTRAL (N),
slowly remove foot pressure from the regular brake
pedal.
Do this until the vehicle is held by the parking
brake only.
To check the PARK (P) mechanism’s holding ability:
With the engine running, shift to PARK
(P). Then
release all brakes.
Underbody Flushing Service At least every spring, use plain water to
flush any
corrosive materials from the underbody. Take care to
clean thoroughly any areas where mud and other debris
can collect.
