1993 BUICK LESABRE ECU

Winter Driving 0 You may want to put winter emergency supplies in
your trunk.
Here are some tips for winter driving:
0 Have your Buick in good shape for winter. Be sure
your engine coolant mix
is correct.
0 Snow tires can help in loose snow, but they may give
you less traction
on ice than regular tires. If you do
not expect
to be driving in deep snow, but may have
to travel over ice, you may not want to switch to
snow tires at all. Include an ice scraper,
a small brush
or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth, and a
couple
of reflective warning triangles. And, if you will be
driving under severe conditions, include a small bag
of
sand, a piece of old carpet or a couple of burlap bags to
help provide traction. Be sure you properly secure these
items in your vehicle.

e e Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you
do,
then be sure to seal the holes later when you remove
the hitch. If you don’t seal them, deadly carbon
monoxide
(CO) from your exhaust can get into your
vehicle (see “Carbon Monoxide” in the Index). Dirt
and water can, too.
The bumpers on your vehicle are not intended for
hitches.
Do not attach rental hitches or other
bumper-type hitches to them. adequate.
Be sure to read and follow the instructions for
the trailer brakes
so you’ll be able to install, adjust and
maintain them properly. Because you have anti-lock
brakes, do not try to tap into your vehicle’s brake
system.
If you do, both brake systems won’t work well,
or at all.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly
so
responsive as your vehicle is by itself.
Safety Chains
You should always attach chains between your vehicle
and your trailer.
Cross the safety chains under the
tongue
of the trailer so that the tongue will not drop to
the road if it becomes separated from the hitch.
Instructions about safety chains may be provided by the
hitch manufacturer or by the trailer manufacturer.
Follow the manufacturer’s recommendation for
attaching safety chains. Always leave just enough slack
so you can turn with your rig. And, never allow safety
chains to drag
on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 pounds (450 kg)
loaded, then it needs its own brakes
-- and they must be

~-
Before you start, check the trailer hitch and platform,
safety chains, electrical connector, lights, tires
and
mirror adjustment. If the trailer has electric brakes, start
your vehicle and trailer moving and then apply the
trailer brake controller by hand to be sure the brakes are
working. This lets you check your electrical connection
at the same time.
During your trip, check occasionally
to be sure that the
load is secure, and that the lights and any trailer brakes
are still working.

Before you do anything, turn on the hazard warning
flashers.
When you call, tell the towing service:
That your vehicle has front-wheel drive.
The make, model, and year of your vehicle.
Whether you can still move the shift lever.
If there was an accident, what was damaged.
When the towing service arrives, let
the tow operator
know that this manual contains detailed towing instructions and illustrations. The operator may want to
see them.

When your vehicle is being towed, have the ignition key
off. The steering wheel should be clamped in a
straight-ahead position, with a clamping device designed
for towing service.

column lock for this. The transaxle should be in Neutral
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, don’t
go more than 55 mph (88 kph) or
farther than
500 miles (800 km) or your transaxle will
be damaged.
If these limits must be exceeded, then the
front wheels have to be supported on a dolly.
