3) Loosen the drain plug attached to the
lower part of the radiator and drain the
engine coolant into a suitable container.
4) Reinstall the reservoir and fill it with
engine coolant to the “FULL” line.
5) Tighten the drain plug on the radiator,
fill the radiator with engine coolant and
install the radiator cap.
6) After filling, let the engine idle for about
2 – 3 minutes to get rid of air in the
cooling system. Then, stop the engine.
7) Check the engine coolant level in the
radiator again. If the level has gone
down, add more engine coolant.

WARNING
It is hazardous to remove the radiator
cap when the engine coolant temper-
ature is high, because scalding fluid
and steam may be blown out under
pressure. Wait until the engine cool-
ant temperature has lowered before
removing the cap.

Check that there is washer fluid in the tank
by looking at the washer fluid level gauge
which is attached to the cap of the washer
fluid tank. If the fluid level is near “0” mark,
refill it.
Use a good quality windshield washer
fluid, diluted with water as necessary.
Air Cleaner
54G421
(1) Mass air flow sensor
If the air cleaner is clogged with dust, there
will be greater intake resistance, resulting
in decreased power output and increased
fuel consumption.
To remove the air cleaner element:
1) Loosen the clamp of the hose and
detach the hose from the cover.
2) Remove the connector of the Mass air
flow sensor.
3) Unclamp the side clamps.
4) With the right end of the cleaner cover
lifted, move the cover to the left to
remove it.
5) Remove the element from the air
cleaner. If it appears to be dirty, replace
it with a new one.
WARNING
Do not use “anti-freeze” solution in
the windshield washer reservoir. This
can severely impair visibility when
sprayed on the windshield, and also
damage your vehicle’s paint.
CAUTION
Damage may result if the washer
motor is operated with no fluid in the
washer tank.

CAUTION
The air cleaner element should be
replaced every 50000 km (30000
miles). More frequent replacement is
necessary when you drive under
dusty conditions.

Spark Plugs
65D180
You should inspect spark plugs periodi-
cally for carbon deposits. When carbon
accumulates on a spark plug, a strong
spark may not be produced. Remove car-
bon deposits with a wire or pin and adjust
the spark plug gap.
To access the spark plugs,
1) disconnect the coupler while pushing
the release lever,
2) remove the bolt, and
3) pull the ignition coil out.

EXAMPLE
CAUTION
 When servicing the iridium/plati-
num spark plugs (slender center
electrode type plugs), do not touch
the center electrode, as it is easy to
damage.
 When installing the spark plugs,
screw them in with your fingers to
avoid stripping the threads.
Tighten with a torque wrench to 25
Nm (2.5 kg-m, 18.0 lb-ft). Do not
allow contaminants to enter the
engine through the spark plug
holes when the plugs are removed.
 Never use spark plugs with the
wrong thread size.
CAUTION
When replacing spark plugs, you
should use the brand and type speci-
fied for your vehicle. For the speci-
fied plugs, refer to the
“SPECIFICATIONS” section at the
end of this book. If you wish to use a
brand of spark plug other than the
specified plugs, consult your SUZUKI
dealer.

Check the parking brake for proper adjust-
ment by counting the number of clicks
made by the ratchet teeth as you slowly
pull up on the parking brake lever to the
point of full engagement. The parking
brake lever should stop between the speci-
fied ratchet teeth and the rear wheels
should be securely locked. If the parking
brake is not properly adjusted or the
brakes drag after the lever has been fully
released, have the parking brake
inspected and/or adjusted by your SUZUKI
dealer.
Steering Wheel
65D187
Check the play of the steering wheel by
gently turning it from left to right and mea-
suring the distance that it moves before
you feel slight resistance. The play should
be between the specified values. Check
that the steering wheel turns easily and
smoothly without rattling by turning it all
the way to the right and to the left while
driving very slowly in an open area. If the
amount of free play is outside the specifi-
cation or you find anything else to be
wrong, an inspection must be performed
by your SUZUKI dealer.

sure of Original Tires
 Size of Compact Spare Tire
 Recommended Cold Tire Inflation Pres-
sure of Compact Spare TireMeasuring Air Pressure
Use the following steps to achieve proper
tire inflation:
1) Identify the recommended tire pressure
on the vehicle’s Tire and Loading Infor-
mation Label or in the owner’s manual.
2) Remove the valve cap from the tire
valve stem.
3) Using a reliable pressure gauge, mea-
sure the tire inflation pressure by press-
ing the tire gauge firmly onto the valve
to get a pressure measurement.
Remember that inflation pressures
should be checked when the tires are
“cold”, meaning before they have been
driven one mile or after sitting for three
hours or more allowing the tire to cool
to ambient air temperature.
4) If the air pressure is too high, slowly
release the air by pressing on the tire
valve stem with the edge of the tire
gauge until you reach the correct pres-
sure.5) If the air pressure is too low, fill the tire
with air at a service station until it
reaches the recommended pressure.
6) Make sure all tires have the same air
pressure (unless the owner’s manual
indicates otherwise).
Tire InspectionInspect your vehicle’s tires at least once a
month by performing the following checks:
1) Measure the air pressure with a tire
gauge. Adjust the pressure if neces-

WARNING
 Air pressures should be checked
when the tires are cold or you may
get inaccurate readings.
 Check the inflation pressure from
time to time while inflating the tire
gradually, until the specified pres-
sure is obtained.
 Never underinflate or overinflate
the tires.
Underinflation can cause unusual
handling characteristics or can
cause the rim to slip on the tire
bead, resulting in an accident or
damage to the tire or rim.
Underinflation can also cause tires
to overheat, leading to tire failure.
Overinflation can cause the tire to
burst, resulting in personal injury.
Overinflation can also cause
unusual handling characteristics
which may result in an accident.

2) Check that the depth of the tread
groove is more than 1.6 mm (0.06 in.).
To help you check this, the tires have
molded-in tread wear indicators in the
grooves. When the indicators appear
on the tread surface, the remaining
depth of the tread is 1.6 mm (0.06 in.)
or less and the tire should be replaced.
3) Check for abnormal wear, cracks and
damage. Any tires with cracks or other
damage should be replaced. If any tires
show abnormal wear, have them
inspected by your SUZUKI dealer.4) Check for loose wheel nuts.
5) Check that there are no nails, stones or
other objects sticking into the tires.
WARNING
Hitting curbs and running over rocks
can damage tires and affect wheel
alignment. Be sure to have tires and
wheel alignment checked periodi-
cally by your SUZUKI dealer.
WARNING
Your SUZUKI is equipped with tires
which are all the same type and size.
This is important to ensure proper
steering and handling of the vehicle.
Never mix tires of different size or
type on the four wheels of your vehi-
cle. The size and type of tires used
should be only those approved by
SUZUKI Motor Corporation as stan-
dard or optional equipment for your
vehicle.
CAUTION
For All-wheel drive (AWD) models,
replacing a tire with one of a different
size, or using different brands among
the four tires can result in damage to
the drive train.
WARNING
Replacing the wheels and tires
equipped on your vehicle with certain
combinations of aftermarket wheels
and tires can significantly change the
steering and handling characteristics
of your vehicle. Oversized tires may
also rub against the fender over
bumps, causing vehicle damage or
tire failure. Therefore, use only those
wheel and tire combinations
approved by SUZUKI Motor Corpora-
tion as standard or optional equip-
ment for your vehicle. For
information regarding the specified
tires, refer to the Tire Information
Label located on the driver’s side
door pillar or the “SPECIFICATIONS”
