tion, an indicator light will come on when
the air conditioning system is on. To turn
off the air conditioning system, push the
“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 compres-
sor turns on or off to maintain the
desired temperature. Less operation of
the compressor results in better fuel
economy.
NOTE:
• If you select RECIRCULATED AIR for an
extended period of time, the air in the
vehicle can become contaminated.
Therefore, you should occasionally
select FRESH AIR.
• If your vehicle has been left in the sun
with the windows closed, it will cool
faster if you open the windows briefly
while you operate the air conditioner with
the air intake selector at FRESH AIR and
the blower at high speed.
Dehumidifying
Set the air flow selector to a desired air
flow selector position, the temperature
selector to the desired temperature posi-
tion and the blower speed selector to the
desired blower speed position. Also select
FRESH AIR and turn on the “A/C” switch.NOTE:
Because the air conditioner dehumidifies
the air, turning it on will help keep the win-
dows clear, even when blowing heated air
using the DEFROST or HEAT &
DEFROST functions.
53MH0511
NOTE:
If you need maximum defrosting:
• set the air flow selector to DEFROST,
• set the blower speed selector to high,
• adjust the temperature selector to the
hot end, and
• adjust the side outlets so the air blows
on the side windows.
Maintenance
If you do not use the air conditioner for a
long period, such as during winter, it may
not give the best performance when you
start using it again. To help maintain opti-
mum performance and durability of your air
conditioner, it needs to be run periodically.
Operate the air conditioner at least once a
month for one minute with the engine
idling. This circulates the refrigerant and oil
and helps protect the internal components.
NOTE:
Your vehicle uses the air conditioning
refrigerant HFC-134a, commonly called
“R-134a”. R-134a replaced R-12 around
1993 for automotive applications. Other
refrigerants are available, including recy-
cled R-12, but only R-134a should be used
in your vehicle.
EXAMPLE
NOTICE
Using the wrong refrigerant may
damage your air conditioning sys-
tem. Use R-134a only. Do not mix or
replace the R-134a with other refrig-
erants.

Engine Hood
53MH0515
To open the engine hood:
1) Pull the hood release handle located on
the outboard side of the driver’s side.
This will disengage the engine hood
lock halfway.
53MM05009
2) Push the under-hood release lever
sideways with your finger, as shown in
the illustration. While pushing the lever,
lift up the engine hood.
53MM05010
3) Continue to lift up the hood until it is
high enough to support with the prop
rod.
To close the engine hood:
1) Lift the hood up slightly and remove the
prop rod from the hole. Put the prop rod
back to the holding clip.
2) Lower the hood close to the bumper,
then let it drop down. Make sure the
hood is securely latched after closing.
WA R N I N G
Fuel is extremely flammable. Do not
smoke when refueling, and make
sure there are no open flames or
sparks in the area.
WA R N I N G
If you need to replace the fuel cap,
use a Maruti genuine cap. Use of an
improper cap can result in a malfunc-
tion of the fuel system or emission
control system. It may also result in
fuel leakage in the event of an acci-
dent.

EXAMPLE
WA R N I N G
Make sure the hood is fully closed
and latched before driving. If it is not,
it can fly up unexpectedly during
driving, obstructing your view and
resulting in an accident.

WA R N I N G
You should take extreme care when
working on your vehicle to prevent
accidental injury. Here are a few pre-
cautions that you should be espe-
cially careful to observe:
(Continued)
WA R N I N G
(Continued)
• To prevent damage or unintended
activation of the air bag system or
seat belt pretensioner system, be
sure the battery is disconnected
and the ignition switch has been in
the “LOCK” position for at least 90
seconds before performing any
electrical service work on your
vehicle. Do not touch air bag sys-
tem components, seat belt preten-
sioner system components or
wires.
The wires are wrapped with yellow
tape or yellow tubing, and the cou-
plers are yellow for easy identifica-
tion.
• Do not leave the engine running in
garages or other confined areas.
• When the engine is running, keep
hands, clothing, tools, and other
objects away from the fan and drive
belt. Even though the fan may not
be moving, it can automatically
turn on without warning.
(Continued)
WA R N I N G
(Continued)
• When it is necessary to do service
work with the engine running, make
sure that the parking brake is set
fully and the transaxle is in Neutral.
• Do not touch ignition wires or other
ignition system parts when start-
ing the engine or when the engine
is running, or you could receive an
electric shock.
• Be careful not to touch a hot
engine, exhaust manifold and
pipes, muffler, radiator and water
hoses.
• Do not allow smoking, sparks, or
flames around fuel or the battery.
Flammable fumes are present.
• Do not get under your vehicle if it is
supported only with the portable
jack provided in your vehicle.
• Be careful not to cause accidental
short circuits between the positive
and negative battery terminals.
• Keep used oil, coolant, and other
fluids away from children and pets.
Dispose of used fluids properly;
never pour them on the ground,
into sewers, etc.

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

Oil Level Check
68KH066
It is important to keep the engine oil at the
correct level for proper lubrication of your
vehicle’s engine. Check the oil level with
the vehicle on a level surface. The oil level
indication may be inaccurate if the vehicle
is on a slope. The oil level should be
checked either before starting the engine
or at least 5 minutes after stopping the
engine.
Pull out the oil dipstick, wipe oil off with a
clean cloth, insert the dipstick all the way
into the engine, then remove it again. The
oil on the stick should be between the
upper and lower limits shown on the stick.
If the oil level indication is near the lowerlimit, add enough oil to raise the level to the
upper limit.
Refilling
53M-09-007
Remove the oil filler cap and pour oil slowly
through the filler hole to bring the oil level
to the upper limit on the dipstick. Be careful
not to overfill. Too much oil is almost as
bad as too little oil. After refilling, start the
engine and allow it to idle for about a min-
ute. Stop the engine, wait about 5 minutes
and check the oil level again.
Changing Engine Oil and Filter
Drain the engine oil while the engine is still
warm.
1) Remove the oil filler cap.
2) Place a drain pan under the drain plug.
3) Using a wrench, remove the drain plug
and drain out the engine oil.

Tightening torque for drain plug (1):
49 Nm (4.9 kg-m, 36.0 lb-ft)
EXAMPLE
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
EXAMPLE
CAUTION
The engine oil temperature may be
high enough to burn your fingers
when the drain plug is loosened. Wait
until the drain plug is cool enough to
touch with your bare hands.
