1993 BUICK LESABRE service indicator

Engine Coolant Temperature Gage
If you have the Gage Cluster, you have a gage that
shows the engine coolant temperature. If the gage
pointer moves into the red area, your engine
is too hot!
That reading means the same thing as the warning light.
It means that
your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off
the engine as soon as possible.
HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating”
in the Index.
Malfunction Indicator Lamp
(Service Engine Soon Light)
SERVICE
,ENGINE SOON
SERVICE
ENGINE
SOON
A computer monitors operation of your fuel, ignition
and emission control systems. This light should come
on
when the ignition is on, but the engine is not running, as
a check to show
you it is working. If it does not come on
at all, have
it fixed right away. If it stays on, or it comes
on while you are driving, the computer
is indicating that
you have a problem. You should take your vehicIe in for
service soon.

Traction Control System (Option)
Your vehicle may have a traction control system that
limits wheel spin. This is especially
useful in slippery
road conditions. The traction control system works at
low speeds only, such
as when you accelerate from a
stop. It applies brake pressure
to an individual wheel
that the system senses is about to spin.
You may feel the system working, or
you may notice
some noise, but this is normal.
OFF
The “TRACTION OFF” warning light lets you know if
your traction control system is not working. See
“Traction Control System Warning Light” in the Index.
Disc Brake Wear Indicators
Your Buick has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come and
go or be heard all the time your vehicle is moving (except
when you are pushing
on the brake pedal firmly).
A CAUTION:
0
The brake wear warning sound means that
sooner or later your brakes won’t work well. That
could lead to an accident. When you hear the
brake wear warning sound, have your vehicle
serviced.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
1 LC3

c:
The tire has a bump, bulge or split.
The tire has a puncture, cut, or other damage that can’t be repaired well because of the size or location
.
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number. That way,
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by a
“MS”
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias, bias-belted or radial) as your original tires.
TREAD WEAR INDICATORS
You need a new tire if:
you can see the indicators at three places around the
tire.
You can see cord or fabric showing through the tire’s
rubber.
The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
