Main Fuse and Primary Fuses
The main fuse and primary fuses are
located in the engine compartment. If the
main fuse blows, no electrical component
will function. If a primary fuse blows, no
electrical component in the corresponding
load group will function. When replacing the
main fuse or a primary fuse, use a MARUTI
genuine replacement.
If the main fuse or a primary fuse
blows, be sure to have your vehicle
inspected by an authorized MARUTI
SUZUKI dealer. Always use a MARUTI
genuine replacement. Never use a
substitute such as a wire even for a
temporary repair, or extensive
electrical damage and a fire can result.

JUMP STARTING INSTRUCTIONS Never attempt to jump start yourvehicle if the battery appears to be
frozen. Batteries in this condition
may explode or rupture if jump
starting is attempted.
When making jump lead connections, be certain that your
hands and the jump leads remain
clear from pulleys, belts, or fans.
Batteries produce flammable hydrogen gas. Keep flames and
sparks away from the battery or an
explosion may occur. Never smoke
when working in the vicinity of the
battery.
If the booster battery you use for jump starting is installed in another
vehicle, make sure the two vehicles
are not touching each other.
If your battery discharges repeatedly, for no apparent reason,
have your vehicle inspected by an
authorized MARUTI SUZUKI dealer.
To avoid harm to yourself or damage to your vehicle or battery,
follow the jump starting instructions
below precisely and in order. If you
are in doubt, call MARUTI SUZUKI
authorized workshop.

Vehicle equipped with electronic fuelinjection system will not start by
pushing or towing as the fuel pump
will not work in this condition. This
starting method could also result in
permanent damage to the catalytic
converter. Use jump leads to start a
vehicle with a weak or flat battery. When jump starting your vehicle, use the
following procedure:
1) Use only a 12 volt battery to jump start
your vehicle. Position the good 12V
battery close to your vehicle so that the
jump leads will reach both batteries.
When using a battery installed on
another vehicle, DO NOT LET THE
VEHICLES TOUCH. Apply the parking
brakes fully on both vehicles.
2) Turn off all vehicle accessories, except those necessary for safety reasons (for
example, headlights or hazard lights). 3) Make jump lead connections as follows:
a) Connect one end of the first jumplead to the positive (+) terminal of the
flat battery.
b) Connect the other end to the positive
(+) terminal of the booster battery.
c) Connect one end of the second jump lead to the negative (-) terminal of
the booster battery.
d) Make the final connection to an unpainted, heavy metal part of the
engine of the vehicle with the flat
battery.
Never connect the jump lead directly
to the negative (-) terminal of the
discharged battery, or an explosion
may occur.
4) If the booster battery you are using is fitted to another vehicle, start the engine
of the vehicle with the booster battery.
Run the engine at moderate speed.
5) Start the engine of the vehicle with the flat battery.
6) Remove the jump leads in the exact reverse order in which you connected
them.EMERGENCY SERVICE10-3

Manual Transmission
Whenever possible, your vehicle should be
towed from the front with the front wheels
lifted. If the steering and drivetrain are in
good condition, your vehicle may be towed
from the rear with the rear wheels lifted and
the front wheels on the ground. Before
towing, make sure the steering is unlocked
and the transmission is in neutral. I
f the Starter Does Not Operate:
1) Try turning the ignition switch to the
“START” position with the headlights
turned on to determine the battery
condition. If the headlights go
excessively dim or go off, it usually
means that either the battery is flat or
the battery terminal contact is poor.
Recharge the battery or correct battery
terminal contact as necessary.
2) If the headlights remain bright, check the fuses. If the reason for failure of the
starter is not obvious, there may be a
major electrical problem. Have the
vehicle inspected by your authorized
MARUTI SUZUKI dealer.
If the Engine is Flooded
If the engine is flooded with petrol, it may
be hard to start. If this happens, press the
accelerator pedal all the way to the floor
and hold it there while cranking the engine.
(Do not operate the starter motor for more
than 15 seconds). Release the accelerator
as soon as the engine has started.
If the Engine Overheats
The engine could overheat temporarily under
severe driving conditions. If the engine
coolant temperature warning light comes on,
it indicates overheating during driving:TOWING HOOK (If equipped)

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.)
It is dangerous to remove the radiator
cap when the water temperature 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 warning.

1) Turn off the air conditioner, if equipped.
2) Take the vehicle to a safe place and
park.
3) Let the engine run at normal idle speed for a few minutes until engine coolant
temperature warning light goes off.
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 bonnet 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.
If the engine coolant temperature warning
light does not goes 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

kept clean and free from dirt. Failure
to keep your vehicle clean may result
in fading of the paint or corrosion to
various parts of the vehicle body.
Washing
Never attempt to wash and wax your vehicle with the engine running.
When cleaning the underside of the
body and fender, where there may
be sharp-edged parts, you should
wear gloves and a longsleeved shirt
to protect your hands and arms
from being cut.
After washing your vehicle, carefully test the brakes before driving to
make sure they have maintained
their normal effectiveness. When washing the vehicle, follow the
instructions below:
1) Flush the underside of body and wheel
housings with pressurized water to
remove mud and debris. Use plenty of
water.
When washing the vehicle, avoid
directing steam or hot water of more
than 80
0C (176
0F) on plastic parts.
2) Remove dirt and mud from the body exterior with running water. You may use
a soft sponge or brush. Do not use hard
materials which can scratch the paint.
3) Wash the entire exterior with a mild
detergent or car wash soap using a
sponge or soft cloth. The sponge or
cloth should be frequently soaked in the
soap solution.
When using a commercial car wash
product, observe the cautions
specified by the manufacturer. Never
use strong household detergents or
soaps.
