H. Tire Ply Material
These tire markings describe the type
of 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 mphand 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.

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.

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.
80JS025
The front and rear tire pressure specifica-
tions for your vehicle are shown below and
are listed on the Tire and Loading Informa-
tion Label, which is located on the driver’s
door lock pillar. The Tire and Loading Infor-
mation Label contains the following infor-
mation:

 Maximum Allowed Combined Weight of
Occupants and Cargo
 Original Tire Size
 Recommended Cold Tire Inflation Pres-
sure of Original Tires
 Size of Compact Spare Tire Recommended Cold Tire Inflation Pres-
sure of Compact Spare Tire
NOTE:
The tire inflation pressure will change due
to changes in atmospheric pressure, tem-
perature or tire temperature when driving.
To reduce the chance that the low tire
pressure warning light will come on due to
normal changes in temperature and atmo-
spheric pressure, it is important to check
and adjust the tire pressures when the
tires are cold. Tires that appear to be at the
specified pressure when checked after
driving, when the tires are warm, could
have pressure below the specification
when the tires cool down. Also, tires that
are inflated to the specified pressure in a
warm garage may have pressure below the
specification when the vehicle is driven
outside in very cold temperature. If you
adjust the tire pressure in a garage that is
warmer than the outside temperature, you
should add 1 psi to the recommended cold
tire inflation pressure for every 10°F differ-ence between garage temperature and
outside temperature.
Measuring 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-
sary. Remember to check the spare
tire, too. Refer to the “Measuring Air
Pressure” section.
54G136
(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 GradesTreadwear
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 from
the 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.
CAUTION
For intelligent All Wheel Drive (i-
AWD) models, replacing a tire with
one of a different size, or using differ-
ent 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 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.
Tires: 6

9-29INSPECTION AND MAINTENANCE
80J21-03E
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
Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Tire Rotation
54G114
To avoid uneven wear of your tires and to
prolong their life, rotate the tires as illus-
trated. Tires should be rotated as recom-
mended in the periodic maintenance
schedule. After rotation, adjust front and
rear tire pressures to the specification
listed on your vehicle’s Tire and Loading
Information Label.
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Exces-
sive speed, underinflation or exces-
sive loading, either separately or in
combination, can cause heat buildup
and possible tire failure.
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.

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
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.
CAUTION
For intelligent All Wheel Drive (i-
AWD) models, driving with an under-
inflated compact spare tire or over 80
km/h (50 mph) while using a compact
spare tire can result in damage to the
drive train.

Vehicle LoadingYour vehicle was designed for specific load
capacities. The load capacities of your
vehicle are indicated by the Gross Vehicle
Weight Rating (GVWR), the Gross Axle
Weight Rating (GAWR, front and rear), and
the total load capacity, the seating capac-
ity, and the cargo load capacity. The
GVWR and GAWR (front and rear) are
listed on the Safety Certification Label
which is located below the driver’s side
door latch striker. The total load capacity
and seating capacity are listed on the Tire
and Loading Information Label which is
located below the Safety Certification
Label. The cargo load capacity can be
determined as described below.
Cargo Load Capacity – Maximum weight
of cargo and luggage that the vehicle can
safely carry. Cargo load capacity is the dif-
ference between the total load capacity of
the vehicle and the total combined weight
of all vehicle occupants. Refer to “Steps for
Determining Correct Load Limit” for details
on how to determine cargo load capacity.
GVWR – Maximum permissible overall
weight of the fully loaded vehicle (including
all the occupants, accessories and cargo
plus the trailer tongue weight if towing a
trailer).
GAWR – (Front and Rear) Maximum per-
missible weight on an individual axle.Seating Capacity – Maximum number of
occupants the vehicle is designed to carry.
NOTE:
Even though the number of occupants is
within the seating capacity, you still must
make sure that you do not exceed the total
load capacity of the vehicle.
Total Load Capacity – Maximum permissi-
ble weight a vehicle can carry including the
weight of all the occupants, accessories,
cargo, plus trailer tongue weight (if towing
a trailer).
The weight of any accessories already
installed on your vehicle at the time of pur-
chase, or that you or the dealer install after
purchase, must be subtracted from the
total load capacity to determine how much
capacity remains available for occupants,
cargo, and trailer tongue weight (if towing a
trailer). Contact your dealer for further
information.
Actual weight of the loaded vehicle and
actual loads at the front and rear axles can
only be determined by weighing the vehicle
using a vehicle scale. To measure the
weight and load, try making your vehicle to
a highway weighing station, shipping com-
pany or inspection station for trucks, etc.
Compare these weights to the GVWR and
GAWR (front and rear) listed on the Safety
Certification Label. If the gross vehicle
weight or the load on either axle exceeds
these ratings, you must remove enoughweight to bring the load down to the rated
capacity.
WARNING
Never overload your vehicle. Over-
loading your vehicle can cause dam-
age to your tires and lead to poor
steering and braking which can result
in an accident. The gross vehicle
weight (sum of the weights of the
loaded vehicle, driver and passen-
gers) must never exceed the Gross
Vehicle Weight Rating (GVWR) listed
on the Safety Certification Label. In
addition, never distribute a load so
that the weight on either the front or
rear axle exceeds the Gross Axle
Weight Rating (GAWR) listed on the
Safety Certification Label.
WARNING
 Always distribute cargo evenly.
 To avoid personal injury or damage
to your vehicle, always secure
cargo to prevent it from shifting if
the vehicle moves suddenly.
 Place heavier objects on the floor
and as far forward in the cargo area
as possible. Never pile cargo
higher than the top of the seat-
backs.

Steps for Determining Correct Load
Limit
1) Locate the statement “The combined
weight of occupants and cargo should
never exceed XXX kg or XXX lbs” on
your vehicle’s placard.
2) Determine the combined weight of the
driver and passengers that will be riding
in your vehicle.
3) Subtract the combined weight of the
driver and passengers from XXX kg or
XXX lbs.
4) The resulting figure equals the available
amount of cargo and luggage load
capacity. For example, if the “XXX”
amount equals 1400 lbs and there will
be five 150 lb passengers in your vehi-
cle, the amount of available cargo and
luggage load capacity is 650 lbs (1400
– 750 (5 x 150) = 650 lbs).
5) Determine the combined weight of lug-
gage and cargo being loaded on the
vehicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in Step 4.
6) If your vehicle will be towing a trailer,
load from your trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the avail-
able cargo and luggage load capacity of
your vehicle.Vehicle Loading Example
As an example, suppose that the Tire and
Loading Information label on your vehicle
indicates that your vehicle’s total load
capacity is 950 lbs. If you were to drive
your vehicle with one passenger, and the
total combined weight of you and your pas-
senger was 350 lbs, then the cargo and
luggage capacity of your vehicle would be
600 lbs (950 – 350 = 600 lbs).
If you later added 2 more passengers, hav-
ing a combined weight of 325 lbs, the
cargo and luggage capacity of your vehicle
would be reduced from 600 lbs to 275 lbs
(600 – 325 = 275 lbs). As you can see, as
the number and combined weight of vehi-
cle occupants increase, the vehicle’s cargo
and luggage capacity decreases.
Suppose again, that you were to take a trip
in your vehicle with the same three pas-
sengers described above, and you decided
to tow a trailer having a trailer tongue
weight of 75 lbs. The cargo and luggage
capacity would be reduced again, to 200
lbs (275 – 75 = 200 lbs).Determining Compatibility of Tire and
Vehicle Load Limits
The tires on your vehicle, when they are
inflated to the recommended tire inflation
pressure, have a load-carrying capacity
that is greater than the load that will be on
the tires when the vehicle is at its GVWR
or GAWR limit. Never use replacement
tires that have a load-carrying capacity
less than the original tires on your vehicle.
Tire load-carrying capacity information is
molded into the tire sidewall typically
shown as “Max. Load”. Use of replacement
tires with a lower load-carrying capacity
than the original tires, or failure to keep the
tires inflated to recommended tire pres-
sure, may reduce the GVWR or GAWR
limit of your vehicle.
NOTE:
Use of replacement tires with a higher
load-carrying capacity than the original
tires, or using a tire inflation pressure
higher than the recommended tire inflation
pressure, will not increase the GVWR or
GAWR limit of your vehicle.
