Fresh Air (f)
When this mode is selected by moving the
lever to right, outside air is used.
Recirculated Air (g)
When this mode is selected by moving the
lever to left, outside air is shut out and
inside air is recirculated. This mode is suit-
able when driving through dusty or polluted
air such as in a tunnel, or when attempting
to quickly cool down the interior.
NOTE:
If you select RECIRCULATED AIR for an
extended period of time, the air in the vehi-
cle can become contaminated. Therefore,
you should occasionally select FRESH
AIR.
Air conditioning switch (5) (if equipped)
To turn on the air conditioning system, set
the blower speed selector to a position
other than “OFF” and push in the “A/C”
switch. With this “A/C” switch operation, a
indicator light will come on when the air
conditioning system is on. To turn off the
air conditioning system, push “A/C” switch
again.
During operation of the air conditioner, you
may notice slight changes in engine
speed. These changes are normal, the
system is designed so that the compressor
turns on or off to maintain the desired tem-
perature.Less operation of the compressor results
in better fuel economy.
System Operating Instructions
Natural ventilation
Select VENTILATION and FRESH AIR, the
temperature selector to the desired tem-
perature position, and the blower speed
selector to off. Fresh air will flow through
the vehicle during driving.
Forced ventilation
The control settings are the same as for
natural ventilation except you set the
blower speed selector to a position other
than off.
Normal heating (using outside air)
Select HEAT and FRESH AIR, the tem-
perature selector to the desired tempera-
ture position and the blower speed selector
to the desired blower speed position. Set-
ting the blower speed selector to a higher
blower speed position increases heating
efficiency.
Quick heating (using recirculated air)
The control settings are the same as for
normal heating except you select RECIR-
CULATED AIR. If you use this heating
method for an extended period of time, the
air in the vehicle can become contami-
nated and the windows can become misty.
Therefore, use this method only for quick
heating and change to the normal heating
method as soon as possible.Head cooled/Feet warmed heating
Select BI-LEVEL and FRESH AIR, the
temperature selector to the desired tem-
perature position, and the blower speed
selector to the desired blower speed posi-
tion. Unless the temperature selector is in
the fully cold position or fully hot position,
the air that comes out of the center and
side outlets will be cooler than the air that
comes out of the floor outlets.
Normal cooling
Set the air flow selector to VENTILATION,
the temperature selector to the desired
temperature position and the blower speed
selector to the desired blower speed posi-
tion, and turn on the “A/C” switch. Setting
the blower speed selector to a higher
blower speed position increases cooling
efficiency.
You can switch the air intake selector to
either FRESH AIR or RECIRCULATED
AIR as you desire. Choosing RECIRCU-
LATED AIR increases cooling efficiency.
Quick cooling (using recirculated air)
The control settings are the same as for
normal cooling except you select RECIR-
CULATED AIR and the highest blower
speed.
NOTE:
• To turn on the air conditioning system,
push in the “A/C” switch and set the
blower speed selector to a position other
than OFF. With this “A/C” switch opera-

Refill with Oil and Check for Leaks
1) Pour oil through the filler hole and
install the filler cap.
For the approximate capacity of the oil,
refer to the “Capacities” item in the
“SPECIFICATIONS” section.
2) Start the engine and look carefully for
leaks at the oil filter and drain plug. Run
the engine at various speeds for at least
5 minutes.
3) Stop the engine and wait about 5 min-
utes. Check the oil level again and add
oil if necessary. Check for leaks again.
Engine Coolant
Selection of Coolant
To maintain optimum performance and
durability of your engine, use MARUTI
Genuine Coolant or equivalent.
This type of coolant is best for your cooling
system as it:
Helps maintain proper engine tempera-
ture.
Gives proper protection against freezing
and boiling.
Gives proper protection against corro-
sion and rust.
Failure to use the proper coolant can dam-
age your cooling system. Your authorized
MARUTI SUZUKI dealer can help you
select the proper coolant.
Coolant Level Check
Check the coolant level at the reservoir
tank, not at the radiator. With the engine
cool, the coolant level should be between
the “FULL” and “LOW” marks.
NOTICE
• When replacing the oil filter, it is rec-
ommended that you use a genuine
MARUTI SUZUKI replacement filter.
If you use an aftermarket filter, make
sure it is of equivalent quality and
follow the manufacturer’s instruc-
tions.
• Oil leaks from around the oil filter
or drain plug indicate incorrect
installation or gasket damage. If
you find any leaks or are not sure
that the filter has been properly
tightened, have the vehicle
inspected by your MARUTI SUZUKI
dealer.
NOTICE
To avoid damaging your cooling sys-
tem:
• Always use a high quality eth-
yleneglycol base non-silicate type
coolant diluted with distilled water
at the correct mixture concentra-
tion.
• Make sure that the proper mix is 30/
70 coolant to distilled water and in
no case higher than 70/30. Concen-
trations greater than 70/30 coolant
to distilled water will cause over-
heating conditions.
• Do not use straight coolant nor
plain water.
• Do not add extra inhibitors or addi-
tives. They may not be compatible
with your cooling system.
• Do not mix different types of base
coolants. Doing so may result in
accelerated seal wear and/or the
possibility of severe overheating
and extensive engine damage.

EMERGENCY SERVICE
53MH0-74E
If the Engine Overheats
The engine could overheat temporarily
under severe driving conditions. If the high
engine coolant temperature warning light
comes on as overheating during driving:
1) Turn off the air conditioner, if equipped.
2) Take the vehicle to a safe place and
park.
3) Let the engine run at the normal idle
speed for a few minutes until the high
engine coolant temperature warning
light goes off.
If the high engine coolant temperature
warning light does not go off:
1) Turn off the engine and check that the
water pump belt and pulleys are not
damaged or slipping. If any abnormality
is found, correct it.2) Check the coolant level in the reservoir.
If it is found to be lower than the “LOW”
line, look for leaks at the radiator, water
pump, and radiator and heater hoses. If
you locate any leaks that may have
caused the overheating, do not run the
engine until these problems have been
corrected.
3) If you do not find a leak, carefully add
coolant to the reservoir and then the
radiator, if necessary. (Refer to “Engine
Coolant” in the “INSPECTION AND
MAINTENANCE” section.)
NOTE:
If your engine overheats and you are
unsure what to do, contact your MARUTI
SUZUKI dealer.

WA R N I N G
If you see or hear escaping steam,
stop the vehicle in a safe place and
immediately turn off the engine to let
it cool. Do not open the hood when
steam is present. When the steam
can no longer be seen or heard, open
the hood to see if the coolant is still
boiling. If it is, you must wait until it
stops boiling before you proceed.
WA R N I N G
• It is hazardous to remove the radia-
tor cap (or degassing tank cap for a
diesel engine) when the water tem-
perature is high, because scalding
fluid and steam may be blown out
under pressure. The cap should
only be taken off when the coolant
temperature has lowered.
• To help prevent personal injury,
keep hands, tools and clothing
away from the engine cooling fan
and air-conditioner fan (if
equipped). These electric fans can
automatically turn on without warn-
ing.
