Tires
MirrorsCheck to see if your vehicle’s mirrors meet
federal, state and local requirements for
mirrors used on towing vehicles. If they do
not, you must install required mirrors
before you tow.Vehicle/Trailer Weight LimitsBefore towing, you must make sure that
gross trailer weight, gross combined
weight, trailer tongue weight, gross vehicle
weight and gross axle weight (front and
rear) are within specified limits as
described below. You can measure vehicle
and trailer weights using a vehicle scale
and can measure tongue weight using a
bathroom scale.Gross Trailer Weight
60A378
Gross Trailer Weight is the weight of the
trailer plus all cargo in it (measured with
the trailer disconnected from the towing
vehicle). Gross trailer weight must never
exceed 1360 kg (3000 pounds).
If you intend to tow a trailer having a gross
trailer weight greater than 450 kg (1000
pounds), the trailer must be equipped with
trailer brakes.Gross Combined Weight
60A381
Gross Combined Weight is the weight of
the fully loaded vehicle (including all the
occupants, accessories and cargo) plus
the weight of the fully loaded trailer. Gross
combined weight must never exceed:
 2.4 L – 3460 kg (7628 pounds)
 3.2 L – 3530 kg (7782 pounds)
WARNING
When towing a trailer, it is very
important for your vehicle and trailer
to have properly inflated tires. Your
vehicle’s tires should be inflated to
the recommended pressures listed
on your vehicle’s Tire Inflation Pres-
sure label. Inflate trailer tires accord-
ing to the specifications provided by
the trailer manufacturer.

TiresFor safe operation of your vehicle, it is
important that the tires be the correct
type and size, in good condition, and
properly inflated. Be sure to follow the
requirements and recommendations in
this section.Tire Sidewall LabelingUseful information about a tire is
molded into its sidewall. The example
below shows a typical passenger car
tire.

A. Tire Manufacturer
The name of the tire manufacturer
is shown here.B. Tire Name/Model
The tire name or model is shown
here.
C. Tire Size
The tire size code is a combina-
tion of letters and numbers used
to define a particular tire’s width,
height, aspect ratio, construction
type, and service description. See
the “Tire Size” explanation later in
this section for more details.
D. U.S. DOT Tire Identification Num-
ber
The Department of Transportation
(DOT) marking indicates that the
tire is in compliance with the U.S.
Department of Transportation
Motor Vehicle Safety Standards.
The letters and numbers following
the DOT marking is the Tire Iden-
tification Number (TIN). The TIN
identifies the tire manufacturer
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 sup-
port in normal service.
G. Max Inflation Pressure
Max inflation pressure is the max-
imum inflation pressure a tire is
designed for.
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 carrying 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.)

79K21-03E Tire Inflation Pressure
Tire 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 Loading Information Label, which
is located on the driver’s door lock pil-
lar. The Tire and Loading Information
Label contains the following informa-
tion:
 Seating Capacity
 Maximum Allowed Combined
Weight of Occupants and Cargo
 Original Tire Size Recommended Cold Tire Inflation
Pressure of Original Tires
NOTE:
The tire inflation pressure will change
due to changes in atmospheric pres-
sure, temperature 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 atmospheric pres-
sure, 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 pres-
sure in a warm garage may have pres-
sure below the specification when the
vehicle is driven outside in very coldtemperature. 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 difference between garage tem-
perature and outside temperature.
Measuring air pressure
Use the following steps to achieve
proper tire inflation:
1) Identify the recommended tire pres-
sure on the vehicle’s Tire and Load-
ing Information Label or in the
owner’s manual.
2) Remove the valve cap from the tire
valve stem.
3) Using a reliable pressure gauge,
measure the tire inflation pressure
by pressing 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 tempera-
ture.
4) If the air pressure is too high, slowly
release the air by pressing on the
tire valve stem with the edge of the
Recommended Cold Tire Inflation

tire gauge until you reach the cor-
rect pressure.
5) If the air pressure is too low, fill the
tire with air at a service station until
it reaches the recommended pres-
sure.
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 fol-
lowing checks:
1) Measure the air pressure with a tire
gauge. Adjust the pressure if nec-
essary. Remember to check the
spare tire, too. Refer to the “Mea-
suring Air Pressure” section.

WARNING
 Air pressures should be
checked when the tires are cold
or you may get inaccurate read-
ings.
 Check the inflation pressure
from time to time while inflating
the tire gradually, until the spec-
ified pressure is obtained.
(Continued)
WARNING
(Continued) Never underinflate or overin-
flate the tires.
Underinflation can cause
unusual handling characteris-
tics 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 characteris-
tics which may result in an acci-
dent.

INSPECTION AND MAINTENANCE
79K21-03E Snow Tires
Your vehicle is equipped with all-sea-
son 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 vehi-
cle.
GLOSSARY OF TIRE TERMI-
NOLOGYAccessory Weight – the combined
weight (in excess of those standard
items which may be replaced) of auto-
matic transmission, power steering,
power brakes, power windows, power
seats, radio, and heater, to the extent
that these items are available as fac-
tory-installed equipment (whether
installed or not).
Cold Tire Inflation Pressure – the pres-
sure in a tire that has been driven less
than 1 mile or has been standing for
three hours or more.
Curb Weight – the weight of a motor
vehicle with standard equipment
including the maximum capacity of
fuel, oil, and coolant, and, if so
equipped, air conditioning and addi-
tional weight optional engine.
Intended Outboard Sidewall – (1) the
sidewall that contains a whitewall,
bears white lettering or bears manu-
facturer, brand, and/or model name
molding that is higher or deeper than
the same molding on the other side-
wall of the tire, or (2) the outward fac-
ing sidewall of an asymmetrical tire
that has a particular side that mustalways face outward when mounted
on a vehicle.
Maximum Inflation Pressure – the
maximum cold inflation pressure a tire
is designed to support in normal ser-
vice.
Maximum Loaded Vehicle Weight –
the sum of curb weight, accessory
weight, vehicle capacity weight (total
load capacity), and production options
weight.
Normal Occupant Weight – 68 kilo-
grams times the number of occupants
specified in the second column of
Table 1 (shown below).
Occupant distribution – distribution of
occupants in a vehicle as specified in
the third column of Table 1 (shown
below).
Production Options Weight – the com-
bined weight of those installed regular
production options weighing over 2.3
kilograms in excess of those standard
items which they replace, not previ-
ously considered in curb weight or
accessory weight, including heavy
duty brakes, ride levelers, roof rack,
heavy duty battery, and special trim.
WARNING
(Continued) 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.
 Replace the spare tire with a
new one as soon as the tread
wear indicator appears.
 When replacing the spare tire,
use a replacement tire with the
exact same size and construc-
tion.

Recommended Inflation Pressure –
the cold tire inflation pressure recom-
mended by a manufacturer.
Rim – metal support for a tire or tire
and tube assembly upon which the tire
beads are seated.
Vehicle Capacity Weight – the rated
cargo and luggage load plus 68 kilo-
grams (150 lbs) times the vehicle’s
designated seating capacity.
Vehicle Maximum Load on the Tire –
the load on an individual tire that is
determined by distributing to each axle
its share of the maximum loaded vehi-
cle weight and dividing by two.
Vehicle Normal Load on the Tire – the
load on an individual tire that is deter-
mined by distributing to each axle its
share of the curb weight, accessory
weight, and normal occupant weight
(distributed in accordance with Table 1
shown below) and dividing by 2.TABLE 1 – Occupant Loading and
Distribution For Vehicle Normal
Load For Various Designated Seat-
ing Capacities
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 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 Labelwhich is located below the Safety Cer-
tification Label. The cargo load capac-
ity 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 difference between the
total load capacity of the vehicle and
the total combined weight of all vehicle
occupants. Refer to “Steps for Deter-
mining 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, accesso-
ries and cargo plus the trailer tongue
weight if towing a trailer).
GAWR – (Front and Rear) Maximum
permissible 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 Designated

gers in your vehicle, 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
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calcu-
lated 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 available cargo and
luggage load capacity of your vehi-
cle.
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 passenger 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,
having a combined weight of 325 lbs,
the cargo and luggage capacity of
your vehicle would be reduced from600 lbs to 275 lbs (600 – 325 = 275
lbs). As you can see, as the number
and combined weight of vehicle occu-
pants 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 passengers 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-carry-
ing 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 replace-
ment tires with a lower load-carrying
capacity than the original tires, or fail-
ure to keep the tires inflated to recom-
mended tire pressure, may reduce the
GVWR or GAWR limit of your vehicle.NOTE:
Use of replacement tires with a higher
load-carrying capacity than the origi-
nal tires, or using a tire inflation pres-
sure higher than the recommended
tire inflation pressure, will not increase
the GVWR or GAWR limit of your vehi-
cle.
