Loading Your VehicleIt is very important to know how much
weight your vehicle can carry. The load
capacities of your vehicle are indicated by
the Gross Vehicle Weight Rating (GVWR),
the Gross Axle Weight Rating (GAWR,
front and rear), the total load capacity, the
seating capacity, 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 on the center pillar, near
the driver’s door latch.
The Tire and Loading Information label
also gives you the size and recommended
inflation pressure for the factory installed,
original equipment tires on your vehicle.
For more information on tires and inflation,
see “Tires” in section 5.Tire and Loading Information Label
Certification Label
The cargo load capacity can be deter-
mined as described below.
Cargo Load Capacity – Maximum weight
of cargo and luggage that the vehicle cansafely 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
and cargo.
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
and cargo. Contact your SUZUKI dealer for
further information.

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 onthe 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.
Towing a TrailerDo not use your vehicle to tow a trailer. The
vehicle is not designed or intended for
such use. Towing a trailer can adversely
affect handling, durability and fuel econ-
omy.
WARNING
Things you put inside your vehicle
can strike and injure people in a sud-
den stop or turn, or in a crash.
Put things in the trunk or rear area
of your vehicle. In a trunk, put them
as far forward as you can. Try to
spread the weight evenly. If you
have fold-down rear seats, you’ll
find four anchors on the back wall
of your trunk. You can use these
anchors to tie down lighter loads.
They’re not strong enough for
heavy things, however, so put them
as far forward as you can in the
trunk or rear area.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
Don’t leave an unsecured child
restraint in your vehicle.
When you carry something inside
the vehicle, secure it whenever you
can.
Don’t leave a seat folded down
unless you need to.

Windshield Wiper Blade
ReplacementWindshield wiper blades should be
inspected at least twice a year for wear or
cracking. If the wiper blades become brittle
or damaged, or make streaks when wiping,
replace the wiper blades for optimum driv-
ing visibility. Replacement blades come in
different types and are removed in different
ways.
Here’s how to remove the Shepherd’s
Hook type:
1) Pull the windshield wiper arm away
from the windshield.
2) Press the retaining clip (A) and pull the
wiper blade off the arm.
3) Install a new blade by reversing the
steps 1 and 2.
TiresYour new vehicle comes with high-quality
tires made by a leading tire manufacturer.

warranty and where to obtain service, see
your SUZUKI Warranty booklet for details.
For additional information refer to the tire
manufacturer’s booklet included with your
vehicle’s Owner’s Manual.
Tire Sidewall LabelingUseful information about a tire is molded
into its sidewall. The examples below show
a typical passenger car tire and a spare
tire sidewall.
Passenger Car Tire Example
A. Tire Size
The tire size is a combination of let-
ters and numbers used to define a
particular tire’s width, height, aspect
ratio, construction type and service
description. See the “Tire Size” illus-
WARNING
Poorly maintained and improperly
used tires are dangerous.
Overloading your tires can cause
overheating as a result of too much
friction. You could have an air-out
and a serious accident. See “Load-
ing Your Vehicle” in the Index.
Under inflated tires pose the same
danger as overloaded tires. The
resulting accident could cause
serious injury. Check all tires fre-
quently to maintain the recom-
mended pressure. Tire pressure
should be checked when your tires
are cold.
Overi nflated tires are more likely to
be cut, punctured or broken by a
sudden impact – such as when you
hit a pothole. Keep tires at the rec-
ommended pressure.

WARNING
(Continued)
Worn, old tires can cause acci-
dents. If your tread is badly worn,
or if your tires have been damaged,
replace them.

Code
The Department of Transportation
(DOT) code indicates that the tire is in
compliance with the U.S. Department
of Transportation Motor Vehicle
Safety Standards.
C. Tire Identification Number (TIN)
The letters and numbers following the
DOT code are the Tire Identification
Number (TIN). The TIN shows the
manufacturer and plant code, tire size
and the date the tire was manufac-
tured. The TIN is molded on to both
sides of the tire, although only one
side may have the date of manufac-
ture.
D. Tire Ply Material

in the sidewall and under the tread.
E. Uniform Tire Quality Grading (UTQG)
Tire manufacturers are required to
grade tires based on three perfor-
mance factors: treadwear, traction
and temperature resistance.
F. Maximum Cold Inflation Load Limit
Maximum load that can be carried
and the maximum pressure needed to
support that load.
G. 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 maximuminflation 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.Compact Spare Tire Example
A. Temporary Use Only Marking
The compact spare tire should not be
driven at speeds over 50 mph (80 km/
h). The compact spare tire is for
emergency use when a regular road
tire has lost air and gone flat. See
“Compact Spare Tire” and “If a Tire
Goes Flat” in this section.
B. Tire Ply Material
The type of cord and number of plies
in the sidewall and under the tread.
C. Tire Identification Number (TIN)

spare tire should be inflated to 60 psi
(420 kPa). For more information on
tire pressure and inflation, see “Tire
Inflation Pressure” in this section.
F. T i r e S i z e
A combination of letters and numbers
defining a tire’s width, height, aspect
ratio, construction type and service
description. The letter “T” as the first
character in the tire size means the
tire is for temporary use only.
Tire Size
The following illustration shows an exam-
ple of a typical passenger car tire size.
A. Tire Type
This letter code indicates the primary
intended use of the tire. The “P” as
the first character in the tire size
means a passenger vehicle tire engi-
neered to standards set by the U.S.
Tire and Rim Association.
B. Tire Width
The three-digit number indicates the
tire section width in millimeters from
sidewall to sidewall.
C. Aspect Ratio
A two-digit number that indicates the
tire height-to-width measurements.
For example, if the tire size aspect
ratio is “70”, as shown in item “C” of
the illustration, it would mean that thetire’s sidewall is 70% as high as it is
wide.
D. Construction Code
A letter code is used to indicate the
type of ply construction in the tire. The
letter “R” means radial ply construc-
tion, the letter “D” means diagonal or
bias ply construction; and the letter
“B” means belted-bias ply construc-
tion.
E. Rim Diameter
Diameter of the wheel in inches.
F. Service Description
These characters represent the load
range and the speed rating of a tire.
The load range represents the load
carrying capacity a tire is certified to
carry. The speed rating is the maxi-
mum speed a tire is certified to carry
a load. Speed ratings range from “A”
to “Z”.
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 Pressure Monitoring
SystemIf your vehicle is equipped with a tire pres-
sure monitoring system, it uses pressure
sensors containing a unique identification
code to monitor the inflation pressure of
the tires. When the inflation pressure of
one or more tires indicates significant
under-inflation, the tire pressure warning
light comes on. If the warning light blinks,
for approximately one minute and then illu-
minates continuously, the monitoring sys-
tem may not be working. For more
information, see “Tire Pressure Monitoring
System Warning Light” in section 3.
The tire pressure monitoring system does
not replace normal tire maintenance. See
“Inflation – Tire Pressure & Correcting the
Tire Pressure” in this section for more
information.
The tire pressure warning light can come
on due to normal causes such as natural
air leaks and pressure changes caused by
changes in temperature or atmospheric
pressure. Adjusting the air pressure in the
tires to the pressure shown on the tire and
loading information label should cause the
tire pressure warning light to turn off.
If you use new wheels with new tire infla-
tion pressure sensors, their ID codes must
be programmed into the tire pressure mon-
WARNING
If the tire pressure warning light does
not come on when the ignition is
turned to the “ON” position, or
comes on and blinks while driving
there may be a problem with the tire
pressure monitoring system. Have
your vehicle inspected by an autho-
rized dealer.
WARNING
If the tire pressure warning light
comes on and stays on, reduce your
speed and avoid abrupt steering and
braking. Stop in a safe place as soon
as possible and check your tires.
If you have a flat tire, replace it with
a spare tire. Refer to “Changing a
Flat Tire” in section 5.
If one or more of your tires is
under-inflated, adjust the inflation
pressure in all of your tires to the
recommended inflation pressure as
soon as possible.
Be aware that driving on a signifi-
cantly under-inflated tire can cause
the tire to overheat and can lead to
tire failure, and may affect steering
control and brake effectiveness. This
could lead to an accident, resulting in
severe injury or death.
CAUTION
Do not use liquid sealants for a flat
tire as air pressure sensors can be
damaged.
In case of tire a bursting or sudden
pressure drops, the tire pressure
monitoring system warning light
may not come on immediately.
The inflation pressures vary with
the ambient temperature. If the
vehicle is subjected to large varia-
tions in ambient temperature, the
tire
inflation pressure may be
under-inflated when the ambient
temperature is relatively low. If the
warning light comes on, adjust the
tire inflation pressure.
The tire pressure sensors can be
damaged by the installation or
removal of tires. When tires must
be repaired or replaced, we highly
recommend that you have them
repaired or replaced by your
SUZUKI dealer.
If the tire pressure warning light
comes on or blinks frequently,
there may be something wrong
with one of the tires or with the
monitoring system. Have your vehi-
cle inspected by your SUZUKI
dealer.

itoring system. Have tire and wheel
replacement performed by an authorized
service facility to avoid the risk of damag-
ing the tire pressure monitor sensors.
The tire pressure monitoring system may
not work normally in the following circum-
stances:
Wheels other than genuine wheels are
being used.
Wheels whose ID codes are not memo-
rized by the vehicle are used. The moni-
toring system should be set up by an
authorized service facility.
Wheels that are not fitted with tire pres-
sure sensors are being used.
The tire inflation pressure sensors’ bat-
tery is exhausted.
A wireless facility or device using the
same frequency is near the vehicle.
Snow or ice is stuck inside the fenders
and/or on the wheels.
The tire pressure monitoring system oper-
ates on a radio frequency subject to Fed-eral Communications Commission (FCC)
Rules and with Industry and Science Can-
ada.
This device complies with Part 15 of the
FCC Rules and with RSS-210 of Industry
and Science Canada. Operation is subject
to the following two conditions: (1) This
device may not cause harmful interference,
and (2) this device must accept any inter-
ference received including interference that
may cause undesired operation of the
device.
NOTE:
Changes or modifications not expressly
approved by the party responsible for com-
pliance could void the user’s authority to
operate the equipment.
NOTE:
Only use tire sizes that are recommended
for your vehicle. Use of inappropriate-size
tires can cause a variety of problems which
will not be covered under warranty.
Correcting the Tire PressureTo permanently eliminate the low tire pres-
sure warning light, you must fill the tires
with the correct amount of air. However, at
the next vehicle start-up, the warning light
will reappear if the tire pressure is not cor-
rected. The best time to check your tire
pressure is when the tires are cold. A Tire
and Loading Information label, located on
the driver’s door near the door latch, shows
the correct inflation pressure for the tires
when they are cold. Cold means your vehi-
cle has been sitting for at least three hours
or driven no more than one mile. You may
notice during cooler conditions that low tire
pressure warning light will appear when
the vehicle is first started and then turn off
as you start to drive the vehicle. This could
be an early indicator that your tire pres-
sures are getting low and need to be
inflated to the proper pressure.
WARNING
Only use tires and wheels recom-
mended by us as standard or
optional equipment for your vehicle.
Use of tires or wheels not recom-
mended by us can result in TPMS fail-
ure. Refer to “Tires” in the “SERVICE
AND APPEARANCE CARE” section
for additional information.
WARNING
We highly recommend that any TPMS
sensor replacement or tire rotation
be done by an authorized Suzuki
dealer. The dealer will make sure that
the TPMS system is set up to recog-
nize the ID codes of the TPMS sen-
sors.
