How the ABS WorksA computer continuously monitors wheel
speed. The computer compares the
changes in wheel speed when braking. If
the wheels slow suddenly, indicating a
skidding situation, the computer will
change braking pressure several times
each second to prevent the wheels from
locking. When you start your vehicle or
when you accelerate after a hard stop, you
may hear a momentary motor or clicking
noise as the system resets or checks itself.
Break-In Catalytic Converter
54G236
The purpose of the catalytic converter is to
minimize the amount of harmful pollutants
in your vehicle’s exhaust. Use of leaded
fuel in vehicles equipped with catalytic
converters is prohibited by federal law,
because lead deactivates the pollutant-
reducing components of the catalyst sys-
tem.
The converter is designed to last the life of
the vehicle under normal usage and when
unleaded fuel is used. No special mainte-
nance is required on the converter. How-
ever, 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 cat-
alyst. This may result in permanent heat
damage to the catalyst and other vehicle
components.
WARNING
The ABS may not work properly if
tires or wheels other than those
specified in the owner’s manual are
used. This is because the ABS works
by comparing changes in wheel
speed. When replacing tires or
wheels, use only the size and type
specified in this owner’s manual.
CAUTION
The future performance and reliabil-
ity 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 960 km (600 miles)
of vehicle operation.
 After starting, do not race the
engine. Warm it up gradually.
 Avoid prolonged vehicle operation
at a constant speed. Moving parts
will break in better if you vary your
speed.
 Start off from a stop slowly. Avoid
full throttle starts.
 Avoid hard stopping, especially
during the first 320 km (200 miles)
of driving.
 Do not drive slowly with the tran-
saxle in a high gear.
 Drive the vehicle at moderate
engine speeds.

54G27-03E
Tire ChainsTire chains should only be used if they are
needed to increase traction or are required
by law. Make sure that the chains you use
are small-link chains or cable-type chains
and are the correct size for your vehicle’s
tires. Also make sure that there is enough
clearance between the fenders and the
chains as installed on the tires.
Install the chains on the front tires tightly,
according to the chain manufacturer’s
instructions. Retighten the chains after
driving about 1.0 km (1/2 mile) if neces-
sary. With the chains installed, drive slowly.Do not drive through deep or rushing
water
Driving in deep or rushing water can be
hazardous. You could lose control of the
vehicle and the occupants could drown.
Also, your vehicle could be seriously dam-
aged. To avoid these risks, observe the fol-
lowing instructions and precautions.
 Do not drive through deep or rushing
water. Deep or rushing water, such as
fast-moving streams or floodwaters,
could carry your vehicle away from your
intended path. The water is too deep if it
covers your wheel hubs, axles or
exhaust tailpipe. Know the depth of the
water before you attempt to drive
through it.
 If water blocks the tailpipe, the engine
may not start or run. If the water is deep
enough to get drawn into the engine
intake system, the engine will be badly
damaged.
 Submerged brakes will have poor brak-
ing performance. Drive slowly and care-
fully. Driving slowly will also help avoid
water splashing onto the ignition system,
which could cause the engine to stall.
 Even when driving through shallow or
still waters, drive carefully since the
water may be hiding ground hazards
such as holes, ditches or bumps.
54G638S
CAUTION
Do not continue rocking the vehicle
for more than a few minutes. Pro-
longed rocking can cause engine
overheating, transaxle or transfer
case damage or tire damage.
CAUTION
If you hear the chains hitting against
the vehicle body while driving, stop
and tighten them.
If your vehicle is equipped with full
wheel caps, remove the wheel caps
before installing the chains or the
wheel caps can be damaged by the
chain bands.
WARNING
In addition to following the driving
tips in this section, it is important to
observe the following precautions.
 Make sure your tires are in good
condition and always maintain the
specified tire pressure. Refer to
“Tires” in the “INSPECTION AND
MAINTENANCE” section for
details.
 Do not use tires other than those
specified by SUZUKI. Never use dif-
ferent sizes or types of tires on the
front and rear wheels. For informa-
tion regarding the specified tires,
refer to the Tire Information Label
located on the driver’s side door
pillar.

WARNING
(Continued)
 Never use oversized tires or special
shocks and springs to raise (jack
up) your vehicle. This will change
its handling characteristics. Over-
sized tires may also rub against the
fender over bumps, causing vehicle
damage or tire failure.
 After driving through water, test the
brakes while driving at a slow
speed to see if they have main-
tained 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 effective-
ness.

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

 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”
section.
CAUTION
Replacing the original tires with tires
of a different size may result in false
speedometer or odometer readings.
Check with your SUZUKI dealer
before purchasing replacement tires
that differ in size from the original
tires.

rear tire pressures to the specification
listed on your vehicle’s Tire and Loading
Information Label.
Compact Spare Tire (if equipped)
54G115
(1) Wear indicator
(2) Indicator location mark
Your vehicle comes equipped with the
compact spare tire. The compact spare is
designed to save space in your storage
area, and its lighter weight makes it easier
to install if a flat tire occurs. It is only
intended for temporary emergency use,
until the conventional tire can be repaired
or replaced. The inflation pressure of the
compact spare tire should be checked at
least monthly. Use a quality pocket-type
inflation pressure gauge and set at 420
kPa (60 psi). At the same time, check that
the tire is stored securely. If it is not,
tighten it.
Note that two or more compact spare tires
should not be used on one vehicle simulta-
neously.
WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose after
a time. The wheel could come off and
cause an accident. When you change
a wheel, remove any rust or dirt from
places where the wheel attaches to
the vehicle. In an emergency, you can
use a cloth or a paper towel to do
this; but be sure to use a scraper or
wire brush later, if you need to, to get
all the rust or dirt off.
WARNING
The compact spare tire and wheel are
intended for temporary emergency
use only. Continuous use of this
spare can result in tire failure and
loss of control. Always observe these
precautions when using this spare:
 Your vehicle will handle differently
with this temporary spare.
 Do not exceed 80 km/h (50 mph)
speed.
 Replace this spare with a standard
tire and wheel as soon as possible.
 Use of this spare will reduce
ground clearance.
 Recommended air pressure for this
spare is 420 kPa (60 psi).
 Do not use tire chains on the com-
pact spare. If you must use tire
chains, rearrange the wheels so
standard tires and wheels are fitted
to the front axle.
 The compact spare tire has a much
shorter tread life than the conven-
tional tires on your vehicle.
Replace the tire as soon as the
tread wear indicator appears.
 When replacing the compact tire,
use a replacement tire with the
exact same size and construction.

wheel from the vehicle.
2) Loosen, but do not remove the wheel
nuts.
3) Jack up the vehicle (follow the jacking
instructions in the “EMERGENCY SER-
VICE” section in this manual).
4) Remove the wheel nuts and wheel.
5) Install the new wheel and replace the
wheel nuts with their cone shaped end
facing the wheel. Tighten each nut
snugly by hand until the wheel is
securely seated on the hub.
54G116
6) Lower the jack and fully tighten the nuts
(to the specified torque) in a crisscross
fashion with a wrench as shown in the
illustration.Snow TiresYour vehicle is equipped with all-season
tires which are designed for use in summer
and most winter conditions. For improved
traction in severe winter conditions,
SUZUKI recommends mounting radial
snow tires on all four wheels. Snow tires
must be the same size as the standard
tires. Also be sure to use the tires of the
same type and brand on all four wheels of
your vehicle.
CAUTION
For All-wheel drive (AWD) models,
driving with an underinflated com-
pact spare tire or over 80 km/h (50
mph) while using a compact spare
tire can result in damage to the drive
train.
