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.

Battery
60A269
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.
WARNING
Batteries produce flammable hydro-
gen gas. Keep flames and sparks
away from the battery or an explosion
may occur. Never smoke when work-
ing near the battery.
WARNING
When checking or servicing the bat-
tery, disconnect the negative cable.
Be careful not to cause a short circuit
by allowing metal objects to contact
the battery posts and the vehicle at
the same time.EXAMPLE
WARNING
To avoid harm to yourself or damage
to your vehicle or battery, follow the
jump starting instructions in the
“EMERGENCY SERVICE” section of
this manual if it is necessary to jump
start your vehicle.
WARNING
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after han-
dling.

WARNING
If the main fuse or a primary fuse
blows, be sure to have your vehicle
inspected by an authorized SUZUKI
dealer. Always use a genuine SUZUKI
replacement. Never use a substitute
such as a wire even for a temporary
fix, or extensive electrical damage
and a fire can result.

NOTE:
Make sure that the fuse box always carries
spare fuses.
Headlight AimingSince special procedures are required, we
recommend you take your vehicle to your
SUZUKI dealer for headlight alignment.
Bulb ReplacementNOTE:
If it is difficult to replace headlight bulbs or
parking light bulbs due to under-hood com-
ponents trust this job to your dealer.
WARNING
Always be sure to replace a blown
fuse with a fuse of the correct amper-
age. Never use a substitute such as
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.
BLOWN OK
WARNING
 Light bulbs can be hot enough to
burn your finger right after being
turned off. This is true especially
for halogen headlight bulbs.
Replace the bulbs after they
become cool enough.
 The headlight bulbs are filled with
pressurized halogen gas. They can
burst and injure you if they are hit
or dropped. Handle them carefully.
CAUTION
The oils from your skin may cause a
halogen bulb to overheat and burst
when the lights are on. Grasp a new
bulb with a clean cloth.
CAUTION
Frequent replacement of a bulb indi-
cates the need for an inspection of
the electrical system. This should be
carried out by your SUZUKI dealer.
