7-5OPERATING YOUR VEHICLERUNNING-IN
The future performance and reliability
of the engine depends on the care
and restraint exercised during its early
life. It is especially important to
observe the following precautions
during the initial 1000 km of vehicle
operation.
After starting, do not race theengine. Warm it up gradually.
Avoid prolonged vehicle operation at a constant speed. Moving parts will
bed in better if you vary your speed.
Do not exceed 100 km/h.
Start off from a stop slowly. Avoid full throttle starts.
If possible, avoid hard braking, especially during the first 300 km
of driving.
Do not drive slowly with the transmission in a high gear.
Drive the vehicle at moderate engine speeds.
CAUTION
Even without reserve power in the
brake system, you can still stop the
vehicle by pressing the brake pedal
harder than normally required.
However, the stopping distance may
be longer.
On loose surface where the wheels
can easily loose traction (such as
gravel, etc.), the stopping distance
required for your vehicle may be
greater than for a comparable vehicle
with a conventional brake system.
Allow for extra stopping distance
when driving on loose surfaces.

CATALYTIC CONVERTERThe purpose of the catalytic converter
installed on your vehicle is to convert
exhaust pollutants to harmless water vapour,
carbon dioxide, and nitrogen. Use of leaded
fuel in vehicles equipped with catalytic
converters is prohibited, because lead
deactivates the pollutant-reducing compo-
nents of the catalyst system.
It is very important to keep the engine
properly tuned. Engine misfiring, which can
result from an improperly tuned engine, may
cause overheating of the catalyst. This may
result in permanent heat damage to the
catalyst and other vehicle components.

OPERATING YOUR VEHICLE
Be careful where you park and drive;
the catalytic converter and other
exhaust components can get very hot.
As with any vehicle, do not park or
operate this vehicle in areas where
combustible materials such as dry
grass or leaves can come in contact
with a hot exhaust system.
ww ww
w WARNING
To minimize the possibility of catalyst
or other vehicle damage:
Maintain the engine in the proper
operating condition.
In the event of an engine
malfunction, particularly one
involving engine misfire or other
apparent loss of performance, have
the vehicle serviced promptly.
Do not turn off the engine or interrupt the ignition when the
transmission is in gear and the
vehicle is in motion.
Do not try to start the engine by pushing or towing the vehicle, or
coasting down a hill.
Do not idle the engine with any spark plug wires disconnected or
removed, such as during diagnostic
testing.
Do not idle the vehicle for
prolonged periods if idling seems
rough or there are other
malfunctions.
Do not allow the fuel tank to get
near the empty level.
CAUTION
IMPROVING FUEL ECONOMYThe following instructions will help you
improve fuel economy.
Avoid excessive idling:
If you are to wait for more than a minute
while you are parked, stop the engine and
start it again later. When warming up a cold
engine, allow the engine to idle for some
time.
Avoid “fast” starts:
Fast starts away from lights or stop signs
will consume fuel unnecessarily and shorten
engine life. Start off slowly.
Avoid unnecessary stops:
Avoid unnecessary deceleration and
stopping. Try to maintain a slow, steady
speed whenever possible. Slowing down
and then accelerating again uses more fuel.
Keep a steady cruising speed:
Keep as constant a speed as road and
traffic conditions will permit.

TRAILER TOWINGYour MARUTI SUZUKI is designed to carry
people and a normal amount of cargo, not
to tow a trailer. Maruti does not recommend
you use your vehicle to tow a trailer. Towing
a trailer can adversely affect handling,
durability, and fuel economy.
Keep the air cleaner clean:
A dirty air cleaner will cause the fuel system
to supply too much fuel to the engine for
the amount of air being supplied. The result
is waste of fuel due to incomplete
combustion.
Keep weight to a minimum:
The heavier the load, the more fuel the
vehicle consumes. Take out any luggage or
cargo when it is not necessary.
Keep tyre pressures correct:
Under-inflation of the tyres can waste fuel
due to increased running resistance of the
tyres. Keep your tyres inflated to the correct
pressure shown on the label on the driver’s
side door or door lock pillar.OPERATING YOUR VEHICLE

76G-74E
Wear Your Seat Belts at All Times.The driver and passengers should
be properly restrained at all times,
using the seatbelts provided. Refer
to the “SEATBELTS” section for
instructions on proper use of the
seat belts.
Never drive while under the
influence of alcohol or other drugs.
Alcohol and drugs can seriously
impair your ability to drive safely,
greatly increasing the risk of injury
to yourself and others. You should
also avoid driving when you are
tired, sick, irritated, or under stress.
HIGH-SPEED DRIVING
When driving down a hill, the engine should be used for braking by shifting to
next lower gear.
Try not to hold the brake pedal down
too long or too often while going
down a steep or long hill. This could
cause the brakes to overheat,
resulting in reduced braking efficiency.
Failure to take this precaution could
result in loss of vehicle control.
When descending a down hill, NEVER
turn the ignition key to the “OFF”
position. Emission control system
damage may result.DRIVING ON SLIPPERY ROADSUnder wet road conditions you should drive
at a lower speed than on dry roads due to
possible slippage of tyres during braking.
When driving on icy, snowcovered, or
muddy roads, reduce your speed and avoid
sudden acceleration, abrupt braking, or
sharp steering movements.
When driving at a high-speed, pay attention
to the following:
Stopping distance progressively increases
with vehicle speed. Apply the brakes far
enough ahead of the stopping point to
allow for the extra stopping distance.
On rainy days, “Aquaplaning” can occur. “Aquaplaning” is the loss of direct
contact between the road surface and
the vehicle’s tyres due to a water film
forming between them. Steering or
braking the vehicle while “Aquaplaning”
can be very difficult, and loss of control
can occur. Keep speed down when the
road surface is wet.
At high speeds, the vehicle may be affected by side winds. Therefore, reduce
speed and be prepared for unexpected
buffeting, which can occur at the exits
of tunnels, when passing by a cut of a
hill, or when being overtaken by large
vehicles, etc.
DRIVING ON HILLS When climbing steep hills, the vehiclemay begin to slow down and show a
lack of power. If this happens, you
should change to a lower gear so that
the engine will again be operating in its
normal power range. Change rapidly to
prevent the vehicle from losing
momentum.

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
