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 CapacitiesVehicle Loading
Your 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 Label
which 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
exceed the total load capacity of the
vehicle.
Total Load Capacity – Maximum per-
missible weight a vehicle can carry
including the weight of all the occu-
pants, accessories, cargo, plus trailer
tongue weight (if towing a trailer).
The weight of any accessories already
installed on your vehicle at the time of
purchase, or that you or the dealer
install after purchase, must be sub-
tracted from the total load capacity to
determine how much capacity remains
available for occupants, cargo, and
trailer tongue weight (if towing a Designated

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 high-
way 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 enough weight to
bring the load down to the rated
capacity.Steps for Determining Correct Load
Limit
1) Locate the statement “The com-
bined weight of occupants and
cargo should never exceed XXX kg
or XXX lbs” on your vehicle’s plac-
ard.
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 lug-
gage load capacity. For example, if
the “XXX” amount equals 1400 lbs
and there will be five 150 lb passen-
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 lug-
gage load capacity of your vehicle.
WARNING
Never overload your vehicle. Over-
loading your vehicle can cause
damage 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 passengers) 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 seatbacks.

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 from
600 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.

INSPECTION AND MAINTENANCE
80J23-03E
Your vehicle is equipped with a battery that
requires infrequent maintenance. You will
never have to add water. You should, how-
ever, periodically check the battery, battery
terminals and battery hold-down bracket
for corrosion. Remove corrosion using a
stiff brush and ammonia mixed with water,
or baking soda mixed with water. After
removing corrosion, rinse with clean water.
The test indicator on the top of the battery
provides information on the condition of
the battery.
If your vehicle is not going to be driven for
a month or longer, disconnect the cable
from the negative terminal of the battery to
help prevent discharge.
FusesYour vehicle has three types of fuses, as
described below:
Main Fuse – The main fuse takes current
directly from the battery.
Primary Fuses – These fuses are between
the main fuse and individual fuses, and are
for electrical load groups.
Individual Fuses – These fuses are for indi-
vidual electrical circuits.
For details on protected circuits, refer to
the “Fuses and Protected Circuits” section
in this manual.
To remove a fuse, use the fuse puller pro-
vided in the fuse box.

The main fuse, primary fuses and some of
the individual fuses are located in the
engine compartment. If the main fuse
blows, no electrical component will func-
tion. If a primary fuse blows, no electrical
component in the corresponding load
group will function. When replacing the
main fuse, a primary fuse or an individual
fuse, use a genuine SUZUKI replacement.
To remove a fuse, use the fuse puller pro-
vided in the fuse box. The amperage of
each fuse is shown in the back of the fuse
box cover.

aluminum foil or wire to replace a
blown fuse. If you replace a fuse and
the new one blows in a short period
of time, you may have a major electri-
cal problem. Have your vehicle
inspected immediately by your
SUZUKI dealer.
