1993 BUICK LESABRE climate control

Rear Passenger ComforTemp (Option)
c.
If your Buick has the Dual Automatic ComforTemp
Climate Control option, it looks like this:
If you have this option,
you can adjust the direction of
the air
flow to the rear seating area. The
following information tells
you how it works.
You will hear a beep each time a button is pushed. The
display will show fan, temperature and mode settings.

PASSENBER CLIMATE CONTROL The right front seat
passenger
can also activate
the dual zone function by
pressing the
WARM or
COOL buttons on the
passenger door.
The indicator above the control will show the difference
from the main temperature setting.
Fan Speeds
Ilr t-
--%-
AUTO
The speed of the blower fan
is controlled automatically
if you have the fan on
AUTO.
If you want the blower fan
to run at a lower speed,
push the
LO button. The
~ blower speed will decrease
with every push of the
button until the lowest
speed is reached.

If your Buick has this climate control system, the
following information tells you how it works.
Your Buick's flow through ventilation system supplies
outside air into
the vehicle when it is moving. When the
heater or air conditioning fan is running, outside air
will
also enter the vehicle.
Fan Speeds
The fan control is used to select the speed you want the
blower to control the air flow.
Lever Controls
The upper lever changes the fan speeds. The lower lever
changes the temperature
of the air coming through your
air outlets.
Air Conditioning
The next three selections cool the air. The air
conditioner won't work well unless all the windows are
closed. On very hot days, open the windows long
enough
to let hot inside air out. This reduces the amount
of work your air conditioner's compressor will have to
do, which should help fuel economy.
Max
This setting provides maximum cooling with the least
amount of work.
MAX recirculates much of the air
inside your vehicle
so it maximizes your air
conditioner's performance and fuel economy.
Norm
Use NORM for normal cooling on hot days. This setting
cools outside air and directs it through the instrument
panel outlets.

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

A CAUTION:
;
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes
or
types (radial and bias-belted tires), the vehicle
may not handle properly, and you could have a
crash. Be sure to use the same size and type
tires
on all four wheels.
It’s all right to drive with your compact spare,
though. It was developed for use on your vehicle.

Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example,
a tire graded 150 would wear one and a half
(1 1/2) times as well on the government course as a tire graded
100. The relative performance
of tires depends
upon the actual conditions
of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to lowest are: A, B,
and C. They represent the tire’s ability to stop on wet
pavement as measured under controlled conditions
on
specified government test surfaces of asphalt and
concrete.
A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to this tire
is based
on braking (straight-ahead) traction tests and does not
include cornering (turning) traction.
Temperature - A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure.
The grade
C corresponds to a level of performance
