If the inside of the vehicle is very warm, drive
for the first few minutes with the windows open
to force the hot, stale air out of the vehicle.
[CF05400( GV)12/95]
Fan speed can be reduced, after a comfortable
temperature has been reached, to provide quieter
system operation.
[CF05600( GV)12/95]
To cool your vehicle using outside air, move the
SELECT knob to NORM A/C, move the TEMP
knob to the end of the blue range (full
counterclockwise) and set the fan to the desired
speed. Cooling your vehicle in this way provides
quieter operation, but it is not as economical as
MAX A/C.
[CF05800( GV)12/95]
The instrument panel registers may be adjusted
to control the quantity and direction of air being
discharged. The thumbwheel controls the volume
of air and the knob in the center of the register
directs the air up and down or side to side.
[CF06000( GV)12/95]
When the SELECT knob is moved to OFF, the
system is off and the fan will not operate.

The Electronic Automatic Temperature Control
(EATC) module is located at the center of the
instrument panel and operates only when the
key is in the ON position.

The EATC feature maintains the temperature
you select and automatically controls the airflow
for your comfort. It also allows you to override
the automatic operation with manual override
buttons.

If you want continuous maximum cooling, push
the BLUE button until60ÊF (16ÊC) isshown in

maximum and disregard the60ÊF (16ÊC)setting
until you select a warmer temperature with the
RED button. If you want continuous maximum
heating, push the RED button until90ÊF (32ÊC)
is shown in the display window. Your EATC
will provide maximum heat regardless of the

[CF10400( GV)12/95]
The RED and BLUE buttons at the upper left of
the Control are for temperature selection. The
RED button will increase the set temperature
and the BLUE button will lower the set
temperature. Pressing a button and releasing it
will change the set temperature one degree.
Holding either button in will rapidly change the
temperature setting in one degree increments to
either65ÊF (18ÊC)(BLUE) or85ÊF(29ÊC)(RED).
Then, the set temperature will jump 5Ê and stop
at either60ÊF (16ÊC)which is maximum cooling
or 90ÊF (32ÊC)which is maximum heating.

temperature setting by several degrees outside
this range will not speed up the heating or
cooling process.

[CF11800( GV)12/95]
Your EATC has six buttons which allow you to
make special selections. The buttons are located
along the bottom edge of the EATC control and
allow you to determine where the air will be
discharged. Pressing any override button
changes the air discharge location only. It does
not affect the ability of the system to control
temperature or the fan speed. Return to fully
Automatic operation by pushing the
AUTOMATIC button.

[CF11900( GV)12/95]
MAX A/C button
[CF12000( GV)12/95]
The MAX A/C feature allows for faster cooling
because air is drawn from inside the car. Using
inside air causes the fan to sound louder which
is normal for this selection. The Display window
will indicate MAX A/C under the selected
temperature. The airflow will be from the
instrument panel registers.

162 [GF04900( BCGV)05/96]In general, this system improves your vehicle's
stability and acceleration performance when road
conditions warrant. Traction Assist
TM
is fully
effective up to approximately 25 mph
(40 km/h). At 25 mph (40 km/h) the function
begins to taper off until it no longer operates
above 34 mph (55 km/h).
[GF05000( BCGV)12/95]
If the Traction Assist
TM
system is cycled
excessively, the system will shut down to
prevent the rear brakes from overheating.
During this shutdown period, the word OFF in
the traction assist switch will be illuminated
showing that the traction assist system is
inoperative. A cooling down period is required
to prevent damage to the rear brakes. This time
period varies and depends on brake usage
during the cooling down period. Anti-Lock
braking is not affected and will function
normally during the cool down period.
[GF05100( BCGV)12/95]
NOTE: Traction-Lok axles are not an available
option on vehicles equipped with
traction assist.

Your vehicle comes with power steering. Power
steering uses energy from the engine to help
steer your vehicle.

[GF05400( ALL)03/96]
If the amount of effort needed to steer your
vehicle changes at a constant vehicle speed, have
the power steering system checked. If the power
steering system breaks down (or if the engine is
turned off), you can steer the vehicle manually
but it takes more effort.

[ER20800( ALL)02/96]
1. Your vehicle has a 12-volt starting system, so
you need to use a 12-volt jumper system.
You will damage your starting motor,
ignition system, and other electrical parts if
you connect them to a 24-volt power supply
(either two 12-volt batteries in series or a
24-volt generator set).

[ER20900( ALL)02/96]
2. Do not disconnect the battery of the disabled
vehicle. You could damage the vehicle's
electrical system.

[ER21000( ALL)02/96]
3. Park the booster vehicle close to the hood of
the disabled vehicle.Make sure the vehicles
do not touch each other.Set the parking
brake on both vehicles and stay clear of the
engine cooling fan and other moving parts.

Your vehicle's coolant protects your engine from
overheating in the summer and from freezing in
the winter. Check the level of the coolant at least
once a month. Simply look at the engine coolant
reservoir located in the engine compartment. To
locate the reservoir, see the diagram of your
vehicle's engine underEngine Type, in this
chapter.
*
[MC12300( ALL)02/96]
The coolant additives also protect the entire
cooling system from internal passageway
corrosion and these additives lubricate the water
pump. The coolant should be serviced as noted
in theMaintenance Schedulebooklet.

When the engine is cool, add a 50/50 mixture of
engine coolant and water to the engine coolant
recovery reservoir Ð DO NOT ADD DIRECTLY
TO THE RADIATOR. Add straight water only in
an emergency, but you should replace it with a
50/50 mixture of coolant and distilled water as
soon as possible.
*
[MC13115( GV)05/96]
Check the coolant level in the coolant recovery
reservoir the next few times you drive the
vehicle. If necessary, add enough of a 50/50
mixture of coolant and water to bring the liquid
level to the fill line on the reservoir.
