Drive Belt
Make sure the drive belt tension is correct.
If the belt is too loose, insufficient battery
charging, engine overheating, poor power
steering, poor air conditioning, or exces-
sive belt wear can result. When you press
the belt with your thumb midway between
the pulleys, there should be a deflection
according to the following chart.
The belts should also be examined to
ensure that they are not damaged.
If you need to replace or adjust the belt
have it done by your MARUTI SUZUKI
dealer.F8D

Be sure that the engine oil you use comes
under the quality classification of SG+, SL,
SM and SN. Select the appropriate oil vis-
cosity according to the above chart.
SAE 5W-30 (1) is the best choice for good
fuel economy, and good starting in cold
weather.

INSPECTION AND MAINTENANCE

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.
