BEFORE DRIVING
53MH0-74E
Electric Power Steering Light
(if equipped)
53M-04-077
This light comes on when the ignition
switch is turned to the “ON” position, and
goes out when the engine is started.
If this light comes on while driving, the
power steering system may not work prop-
erly. Have the system inspected by your
MARUTI SUZUKI dealer.
NOTE:
If the power steering system does not work
properly, you will feel heavier to steer but
you still will be able to steer.
Oil Pressure Light
53M-04-078
This light comes on when the ignition
switch is turned to the “ON” position, and
goes out when the engine is started. Thelight will come on and remain on if there is
insufficient oil pressure. If the light comes
on when driving, pull off the road as soon
as you can and stop the engine.
Check the oil level and add oil if necessary.
If there is enough oil, the lubrication sys-
tem should be inspected by your MARUTI
SUZUKI dealer before you drive the vehi-
cle again.
Charging Light
53M-04-079
This light comes on when the ignition
switch is turned to the “ON” position, and
goes out when the engine is started. The
light will come on and remain on if there is
something wrong with the battery charging
system. If the light comes on when the
engine is running, the charging system
should be inspected immediately by your
MARUTI SUZUKI dealer.
High Engine Coolant Temperature
Warning Light
53M-04-080
When the ignition switch is turned to the
“ON” position, this light comes on briefly so
you can check that the light is working. If
this light blinks while driving, it means the
engine is running hot. Avoid driving condi-
tions that may lead to actual overheating. If
NOTICE
• If you operate the engine with this
light on, severe engine damage can
result.
• Do not rely on the Oil Pressure
Light to indicate the need to add
oil. Be sure to periodically check
the engine oil level.

If the coolant level is below the “LOW”
mark, more coolant should be added.
Remove the reservoir tank cap and add
coolant until the reservoir tank level
reaches the “FULL” mark. Never fill the res-
ervoir tank above the “FULL” mark.

Engine coolant is harmful or fatal if
swallowed or inhaled. Do not drink
antifreeze or coolant solution. If swal-
lowed, do not induce vomiting. Imme-
diately contact a poison control
center or a physician. Avoid inhaling
mist or hot vapors; if inhaled, remove
to fresh air. If coolant gets in eyes,
flush eyes with water and seek medi-
cal attention. Wash thoroughly after
handling. Solution can be poisonous
to animals. Keep out of the reach of
children and animals.
NOTICE
• The mixture you use should con-
tain 50% concentration of anti-
freeze.
• If the lowest ambient temperature
in your area is expected to be –
35°C (–31°F) or below, use higher
concentrations up to 60% following
the instructions on the antifreeze
container.
NOTICE
When putting the cap on the reser-
voir tank, line up the mark on the cap
and the mark on the tank. Failure to
follow this can result in coolant leak-
age.

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.

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.
