7976G-74ESnow Chains
If you must use snow chains to increase tyre
traction, observe the following precautions:
Use cable type chains.
Choose a safe place away from traffic to install the chains.
When installing the chains carefully follow the manufacturer’s instructions.
Install the chains on the front tyres.
With the chains on, drive only at slow and moderate speeds.
If the chain hits the vehicle body while
driving, stop at a safe place and
retighten it as soon as possible.
If snow and/or ice on the road disappear, remove the chains as soon
as possible.
If Your Vehicle Gets Stuck If your vehicle gets stuck in snow, mud,
or sand, follow the directions below:
1) Change back and forth between a forward range (or first gear for manual
transmission) and reverse. This will
create a rocking motion which may give
you enough momentum to free the
vehicle. Press gently on the accelerator
to keep wheel spin to a minimum.
Remove your foot from the accelerator
while changing gear.
Do not race the engine. Excessive wheel
spin will cause the tyres to dig deeper,
making it more difficult to free the
vehicle. 2) If your vehicle remains stuck after a few
minutes of rocking, get another vehicle
to pull you out.
Do not allow anyone to stand near the
vehicle when you are rocking it, and
do not spin the wheels faster than an
indicated 40 km/h on the speedometer.
Personal injury and/or vehicle damage
may result from spinning the wheels
too fast.
Do not continue rocking the vehicle
for more than a few minutes.
Prolonged rocking can cause engine
overheating or transmission damage. Make sure your tyres are in good
condition and always maintain the
specified tyre pressure. Refer to
“TYRES” in the “INSPECTION AND
MAINTENANCE” section for details.
Do not use tyres other than those specified by MARUTI SUZUKI. Never
use different sizes or types of tyres
on the front and rear wheels. For
information regarding the specified
tyres, refer to the “SPECI-
FICATIONS” section.
Never use oversized tyres or special
shock absorbers and springs to
raise (jack up) your vehicle. This will
change the handling characteristics.
After driving through water, test the
brakes while driving at a slow speed
to see if they have maintained their
normal effectiveness. If the brakes
are less effective than normal, dry
them by repeatedly applying the
brakes while driving slowly until the
brakes have regained their normal
effectiveness.

DRIVING TIPS AND SAFE DRIVING
DRIVING ON WET ROADS
When driving on wet roads, avoid driving through large amount of
standing water on the road. Large
amount of water entering the engine
compartment may cause damage to
the engine and or electrical
components.
If stuck in deep water, do not start till water level drops.
Water is incompressible substance, water inside engine is harmful to the
engine.
CAUTION

8176G-74E
especially dangerous when the tyres are
worn, for they allow a larger skid.
Use foot brake in three stages
(1) Warn the vehicle behind you
(2) Gradually apply the brake.
(3) Bring the vehicle to a halt.
3. When driving on a downhill, try not to apply the brake but use the engine
brake effectively. Overuse of the
footbrake may result in total brake
failure.
4. Avoid reckless high speed driving and try
to drive at a safe speed suitable for the
road conditions while maintaining a
constant speed. 5. The higher the speed, the narrower the
driver’s visual range becomes. In such
a state, it is difficult to anticipate any
hazard and the driver feels much
fatigued.
6. Never do sharp handling during high
speed driving. You will lose your control
over your vehicle.
7. When overtaking or changing the lane
while driving at a high speed, keep an
ample vehicle-to-vehicle distance.
Long distance driving
1. Be sure to perform safety checks before
starting a trip.
2. Take rest at certain intervals to prevent an accident which may occur when you
are sleepy or tired.
Braking
1. Use the parking brake when parking
your vehicle and shift the gear shift lever
into the first gear or reverse gear
position for the sake of safety.
2. Don’t use handbraking unless unavoidable. It causes the vehicle to skid
and a rearend collision occur. It is

You should take extreme care when
working on your vehicle to prevent
accidental injury. Here are a few
precautions that you should be
especially careful to observe:
Do not leave the engine running ingarages or other confined areas.
When the engine is running, keep hands, clothing, tools, and other
objects away from the fan and water
pump belt. Even though the fan may
not be moving, it can automatically
turn on without warning. When it is necessary to do service
work with the engine running, make
sure that the parking brake is
applied fully and the transmission is
in Neutral.
Do not touch ignition wires or other
ignition system parts when starting
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 gasoline 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.INSPECTION AND MAINTENANCE9-1

INSPECTION AND MAINTENANCE9-11ENGINE OIL AND FILTERSpecified oil
Be sure that the engine oil you use comes
under the API classification of SF, SG or
SH. The recommended engine oil is SF
20W40 (1). Select the appropriate oil
viscosity according to the above chart.
Oil Level Check
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 lower
limit, add enough oil to raise the level to
the upper limit.
76G-09-00376G-09-004
(1) Preferred
Be sure that the engine oil you use comes
under the quality classification of SG+, SL
& SJ. Select the appropriate oil viscosity
according to the above chart.
SAE 5W30 (1) is the best choice for good
fuel economy, and good starting in cold
weather.
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.

Refilling
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
minute. Stop the engine, wait for five
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 the correct spanner remove thedrain plug and drain out the engine oil.
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.
ww ww
w WARNING
New and used oil can be hazardous.
Children and pets may be harmed by
swallowing new or used oil. Keep new
and used oil and used oil filters away
from children and pets.
Continuous contact with used engine
oil may cause (skin) cancer.
Brief contact with used oil may irritate
skin.
To minimize your exposure to used
oil, wear a long-sleeve shirt and
moistureproof gloves (such as
dishwashing gloves) when changing
oil. If oil contacts your skin, wash
thoroughly with soap and water.
Launder any clothing or rags if wet
with oil.
Recycle or properly dispose of used
oil and filters.
4. Reinstall the drain plug and new gasket. Tighten the plug with a wrench to the
specified torque.
