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 OFF. 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.
NOTICE:
Don’t have your vehicle towed on the drive
wheels, unless you must,
If the vehicle must be
towed on the drive wheels, do not tow the vehicle
more than
500 cumulative miles (800 km) or
exceed
50 mph (80 km/h). Cumulative miles are
defined
as total miles over the life of the vehicle.
For example, your vehicle cannot be towed
500 miles (800 km) each day of a trip totaling
3,000 miles (4800 km). If these limitations must
be exceeded, then the drive wheels have to be
supported on
a dolly.

If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
0 Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (a).
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still
no sign of steam, you can idle the engine
for
two or three minutes while you’re parked, to see if
the warning stops. But then,
if you still have the
warning,
turn off the engine und get everyone out of the
vehicle
until it cools down.
You may decide not to lift the hood but
to get service
help right away.

The coolant level should be at or above the COLD mark
on the overflow hose in the coolant bottle.
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump or somewhere else
in
the cooling system. Heater and radiator
hoses, and other engine
parts, can be very hot. Don’t touch them. If you
do, you can be burned.
Don’t run the engine if there is
a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be
no leak, with the engine on, check to
see if the electric engine cooling fans are running. If the
engine is overheating, both fans should be running. If
they aren’t, your vehicle needs service.

You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about it.

Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused.
If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your dealer before adding equipment to the outside of
your vehicle.
Fuel
The 8th digit of your vehicle identification number
(VIN) shows the code letter for your engine.
You will
find the VIN at the top left of your instrument panel.
(See “Vehicle Identification Number”
in the Index.)
If you have the 3800 engine (VIN Code K), use regular
unleaded gasoline rated at
87 octane or higher. If you’re
using fuel rated at the recommended octane or higher
and you hear heavy knocking, your engine needs
service. But don’t worry
if you hear a little pinging
noise when you‘re accelerating or driving up
a hill.
That’s normal, and you don’t have to
buy a higher
octane fuel to get rid
of pinging. It’s the heavy, constant
knock that means
you have a problem.
If you have the 3800 Supercharged engine (VIN Code
l), use premium unleaded gasoline rated at 91 octane or
higher. With the 3800 Supercharged engine, in
an
emergency, you may be able to use a lower octane -- as
low as 87 -- if heavy knocking does not occur. If you
are using 9
1 or higher octane unleaded gasoline and you
hear heavy knocking, your engine needs service.

At a minimum, the gasoline you use should meet
specifications ASTM
D4814 in the United States and
CGSB 3.5-M93 in Canada. Improved gasoline
specifications have been developed by the American
Automobile Manufacturers Association (AAMA) for
better vehicle performance and engine protection.
Gasolines meeting the AAMA specification could
provide improved driveability and emission control
system protection compared
to other gasolines.
Be sure the posted octane for premium is at least 91 (at
least 89 for middle grade and
87 for regular). If the
octane is less than
87, you may get a heavy knocking
noise when you drive.
If it’s bad enough, it can damage
your engine.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed
to operate on fuels that meet
California specifications. If such
fuels are not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily
on fuels meeting
federal specifications, but emission control system performance
may be affected. The malfunction indicator
lamp on your instrument panel may turn on and/or your
vehicle may fail a smog-check test. If this occurs, return
to your authorized Buick dealer for diagnosis to
determine the cause of failure. In the event it is
determined that the cause of the condition is the type
of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not his fuel
contains MMT. General Motors does
not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may turn on. If this occurs, return to your authorized
Buick dealer for service.
