AIR CONDITIONING

Each time you push the air intake control button, the
mode changes in order from the RECIRCULATED AIR
mode to AUTOMATIC mode to OUTSIDE AIR mode,
then back to the RECIRCULATED AIR mode. Each
indicator light shows which mode is now selected.
1RECIRCULATED mode ± If quick circulation of
cooled air is desired, select this mode.
2EXHAUST GAS AUTOMATIC mode ± If the
outside air contains harmful substances like
exhaust gas (i.e., when the vehicle running just in
front of your vehicle accelerates rapidly), the
system changes automatically from the OUTSIDE
AIR mode (with indicators
2 and 3 on) to the
RECIRCULATED mode (with indicators 1 and 2 on).
3 OUTSIDE AIR mode ± The system will take fresh
outside air into the vehicle. Turning off the air conditioning manually will cancel the
EXHAUST GAS AUTOMATIC mode. If you select the
ªAUTOº mode during fan operating, the air conditioning
turns on and the EXHAUST GAS AUTOMATIC mode
will operate.
For normal use, it is best to keep the air intake control
button set to OUTSIDE AIR mode. If recirculated air is
used
during heating, the windows will fog up more easily.
To change the sensitivity of the sensor switching
between the RECIRCULATED and OUTSIDE AIR in
the AUTOMATIC mode, push the air intake control
button until you hear a beep. The display changes
as illustrated below.
The sensitivity of the sensor can be adjusted only while
the vehicle has stopped.

STARTING AND DRIVING
325
Anti±lock brake system is not designed to shorten the
stopping distance: Always drive at the moderate speed
and maintain a safe distance from the vehicle in front of
you. Compared with vehicles not fitted with an
anti±lock brake system, your vehicle may require a
longer stopping distance in the following cases:
 Driving on rough, gravel or snow±covered roads.
 Driving with tire chains installed.
 Driving over the steps such as the joints on the road.
 Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at designated
pressure: The anti±lock brake system detects vehicle
speeds using the speed sensors for respective wheels'
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed, resulting
in a longer stopping distance.
