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 rear 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.
WARNING
 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 (25 mph)
on the speedometer. Personal
injury and/or vehicle damage may
result from spinning the wheels too
fast.
 Be sure to turn the transfer switch
from “4H” to “4H LOCK” or “4L
LOCK” when the tires slip in “4H”.
The continuing tires slip in “4H”
can cause the limited slip differen-
tial gear damage in the center dif-
ferential.
CAUTION
Release the accelerator pedal when
operating the gearshift lever. Operat-
ing the lever with the engine racing
can damage the gears.
CAUTION
Do not continue rocking the vehicle
for more than a few minutes. Pro-
longed rocking can cause engine
overheating, transmission or trans-
fer case damage or tire damage.
CAUTION
If you hear the chains hitting against
the vehicle body while driving, stop
and tighten them.

WARNING
In addition to following the driving
tips in this section, it is important to
observe the following precautions for
on-road and off-road driving.
 Driver and passengers should wear
seat belts at all times.
 Do not let anyone else drive your
vehicle unless they are also aware
of the vehicle characteristics and
handling differences described in
this section.
 Avoid loaning your vehicle to any-
one unless you accompany them.
 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 Inflation Pressure
Label located on the driver’s side
door pillar or the “SPECIFICA-
TIONS” section.
(Continued)
WARNING
(Continued)
 Never use oversized tires or special
shocks and springs to raise (jack
up) your vehicle. This will raise the
center of gravity of the vehicle and
change its handling characteris-
tics. Oversized tires may also rub
against the fender over bumps,
causing vehicle damage or tire fail-
ure.
 After driving through water, mud or
sandy ground, 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.
 Do not use “4H LOCK” or “4L
LOCK” drive for normal driving.
 After extended operation in mud,
sand or water, have the brakes
inspected by your authorized
SUZUKI dealer as soon as possi-
ble.

C. Tire Size
The tire size code is a combination of
letters and numbers used to define a
particular tire’s width, height, aspect
ratio, construction type, and service
description. See the “Tire Size” expla-
nation later in this section for more
details.
D. U.S. DOT Tire Identification Number
The Department of Transportation
(DOT) marking indicates that the tire
is in compliance with the U.S. Depart-
ment of Transportation Motor Vehicle
Safety Standards. The letters and
numbers following the DOT marking
is the Tire Identification Number
(TIN). The TIN identifies the tire man-
ufacturer and plant, tire size, and date
the tire was manufactured.
E. Uniform Tire Quality Grading (UTQG)
Tire manufacturers are required to
grade tires based on three perfor-
mance factors: treadwear, traction
and temperature resistance. Refer to
the “Uniform Tire Quality Grading”
section for more details.
F. Load Rating
Load rating is the maximum weight a
tire is designed to support in normal
service.
G. Max Inflation Pressure
Max inflation pressure is the maxi-
mum inflation pressure a tire is
designed for.
H. Tire Ply Material
These tire markings describe the typeof cord and number of plies in the
sidewall and under the tread.
I. Load Index and Speed Rating
The two- or three-digit number is the
tire’s load index, the maximum load a
tire can carry at the speed indicated
by its speed symbol at the maximum
inflation pressure. The higher the
number is, the greater the load carry-
ing capacity. The letter symbol
denotes the speed at which a tire is
designed to be driven for extended
periods of time. (Ratings are listed
below.)
*The letters ZR may be used on tires with a
maximum speed capability over 149 mph
and will always be used on tires with a
maximum speed capability over 186 mph.J. M+S Marking
This marking indicates the tire has
some mud and snow capabilities and
is designed for all-season use.

D. Construction Code
This letter code is used to indicate the
type of ply construction in the tire. The
letter “R” means radial ply tire con-
struction, the letter “D” means diago-
nal or bias ply construction, and the
letter “B” means belted-bias ply con-
struction.
E. Rim Diameter
This two-digit number is the wheel or
rim diameter in inches.
Tire Inflation PressureTire inflation pressure should be checked
when the tire is cold. “Cold tire inflation
pressure” is the pressure in a tire that has
been driven less than 1 mile (1.6 km) or
has been standing for three hours or more.
54G307
The front, rear and spare tire pressure
specifications for your vehicle are shown
below and are listed on the Tire and Load-
ing Information Label, which is located on
the driver’s door lock pillar. The Tire and
Loading Information Label contains the fol-
lowing information:

 Recommended Cold Tire Inflation Pres-
sure of Original TiresMeasuring 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.
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. Mixing tires could cause you to
lose control while driving which may
lead to an accident. The size and type
of tires used should be only those
approved by SUZUKI Motor Corpora-
tion as standard or optional equip-
ment for your vehicle.

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-
sary. Remember to check the spare
tire, too. Refer to the “Measuring Air
Pressure” section.

(1) Tread wear indicator
(2) Indicator location mark
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 otherdamage 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
 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.
WARNING
Hitting curbs and running over rocks
can damage tires and affect wheel
alignment. Be sure to have tires and
wheel alignment checked periodically
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.

Uniform Tire Quality GradingThe U.S. National Highway Traffic Safety
Administration has developed a grading
system for evaluating the performance of
passenger car tires. The following informa-
tion will help you understand the grading
system, which applies to vehicles sold in
the U.S. Consult your SUZUKI dealer or
tire retailer for help in choosing the correct
replacement tires for your vehicle.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature ADOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B CAll Passenger Car Tires Must Conform To
Federal Safety Requirements in Addition
To These Grades
Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For
example, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however and may depart significantly fromthe norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to low-
est, are AA, A, B and C. Those grades rep-
resent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.
Temperature – A, B, C
The temperature grades are A (the high-
est), B and C, representing the tire’s resis-
tance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and
excessive temperature can lead to sudden
tire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal
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 characteris-
tics 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.
WARNING
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not
include acceleration, cornering,
hydroplaning or peak traction charac-
teristics.

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
To avoid the removal of the spare
wheel full cover while driving, be
sure to fit the claws (3) of the outer
cover of the spare wheel full cover to
each hole (4) of the inner cover of the
spare wheel full cover.

WARNING
Vehicle equipped with P225/65R17
tires have a spare wheel and tire that
are a different size than the wheels
and tires on the vehicle. The spare
wheel and tire on these vehicles are
intended for temporary emergency
use only. The wheel is painted yellow
to remind you that the wheel and tire
are for temporary use only. Continu-
ous use of this spare can result in tire
failure and loss of control. Always
observe these precautions when
using this spare:
 Be aware that your vehicle will han-
dle differently with this temporary
spare.
 Do not exceed 80 km/h (50 mph)
speed.
 Replace the temporary spare with a
standard tire and wheel as soon as
possible.
 Do not operate your vehicle in “4H
LOCK” or “4L LOCK” with this tem-
porary spare.
 Do not use tire chains on the spare
tire. If you must use tire chains,
rearrange the wheels so standard
tires and wheels are fitted to the
rear axle.

WARNING
(Continued)
 Replace the spare tire with a new
one as soon as the tread wear indi-
cator appears.
 When replacing the spare tire, use
a replacement tire with the exact
same size and construction.
