VEHICLE LOADING AND TOWING
79K21-03E
Trailer TowingYou can use your SUZUKI to tow a trailer,
but you should always observe the require-
ments and recommendations in this sec-
tion. If you intend to tow a trailer, it is
essential to select a trailer and trailer tow-
ing equipment which are compatible. A
reputable trailer dealer can help you.
For Automatic transmission vehicles, shift
into “3” (Low 2) or “L” (Low 1) (if necessary)
and frequently monitor the coolant temper-
ature gauge when towing up a steep hill. If
the gauge indicates overheating, park the
vehicle in a safe place and let the enginecool down. Refer to “If the Engine Over-
heats” section for details on how to deal
with overheating.
HitchesUse only a trailer hitch bracket that is
designed to bolt to the frame of your vehi-
cle, and a hitch that is designed to bolt to
this bracket. We recommend that you use
a genuine SUZUKI trailer hitch bracket and
trailer hitch (available as options), or equiv-
alent.Safety ChainsAlways attach safety chains between your
vehicle and trailer. Cross safety chains
under the tongue of the trailer so that the
tongue will not drop to the road if the trailer
becomes separated from the hitch. Follow
the manufacturer’s recommendation for
attaching safety chains. Always leave just
enough slack to permit full turning. Never
allow safety chains to drag on the road.
Trailer LightsMake sure your trailer is equipped with
lights which meet federal, state and local
requirements. Always check for the proper
operation of all trailer lights before you
start to tow.Brakes CAUTION
Trailer towing puts additional stress
on the engine, drive train and brakes
of your vehicle. Never tow a trailer
during the first 960 km (600 miles) of
vehicle operation.
CAUTION
Because towing a trailer puts addi-
tional stress on your vehicle, more
frequent maintenance will be
required than under normal driving
conditions. Follow the schedule for
Maintenance Recommended Under
Severe Driving Conditions or perform
more frequent maintenance as nec-
essary.
CAUTION
Towing in “D” range up a steep hill
can cause coolant overheating which
may result in engine/automatic trans-
mission damage.
WARNING
Never use a bumper hitch or a hitch
which attaches to the axle of your
vehicle.
WARNING
Never attach safety chains to the
bumper of your vehicle. Secure con-
nections so that they can’t come
loose.
WARNING
Never splice trailer lights directly into
your vehicle’s electrical system, or
electrical system damage may occur.
WARNING
If trailer brakes are used, you should
follow all instructions provided by the
manufacturer. Never tap into the
brake system of your vehicle.

WARNING
You should take extreme care when
working on your vehicle to prevent
accidental injury. Here are a few pre-
cautions that you should be espe-
cially careful to observe:
 To prevent damage or unintended
inflation of the air bag system, be
sure the battery is disconnected
and the ignition switch has been in
the “LOCK” position for at least 90
seconds before performing any
electrical service work on your
SUZUKI. Do not touch air bag sys-
tem components or wires. The
wires are wrapped with yellow tape
or yellow tubing, and the couplers
are yellow for easy identification.
(Continued)
WARNING
(Continued)
 Do not leave the engine running in
garages or other confined areas.
 When the engine is running, keep
hands, clothing, tools and other
objects away from the moving fan
and fan belt.
 When it is necessary to do service
work with the engine running, make
sure that the parking brake is set
fully and the transmission is in
Neutral (for manual transmission
vehicles) or Park (for automatic
transmission vehicles).
 Do not touch ignition wires or other
ignition system parts when starting
the engine or when the engine is
running, or you could receive an
electric shock.
 Be careful not to touch a hot
engine, exhaust manifold and
pipes, muffler, radiator and water
hoses.
 Do not allow smoking, sparks or
flames around fuel or the battery.
Flammable fumes are present.
 Do not get under your vehicle if it is
supported only with the portable
jack provided in your vehicle.
(Continued)
WARNING
(Continued)
 Be careful not to cause accidental
short circuits between the positive
and negative battery terminals.
 Keep used oil, engine coolant and
other fluids away from children and
pets. Dispose of used fluids prop-
erly; never pour them on the
ground, into sewers, etc.

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 CIR-
CUITS” 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.

Bulb ReplacementNOTE:
If it is difficult to replace headlight bulbs or
clearance light bulbs due to under-hood
components trust this job to your dealer.
Center Interior Light (if equipped)
64J159
Pull down the lens by using a flat blade
screwdriver covered with a soft cloth as
shown. To install it, simply push it back in.
The bulb can be removed by simply pulling
it out. When replacing the bulb, make sure
that the contact springs are holding the
bulb securely.
Rear Interior Light (if equipped)
64J160
Pull down the lens by using a flat blade
screwdriver covered with a soft cloth as
shown. To install it, simply push it back in.
The bulb can be removed by simply pulling
it out.
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.

3) Make jumper cable connections as fol-
lows:
1. Connect one end of the first jumper
cable to the positive (+) terminal of
the discharged battery (1).
2. Connect the other end to the positive
(+) terminal of the booster battery
(2).
3. Connect one end of the second
jumper cable to the negative (–) ter-
minal of the booster battery (2).
4. Make the final connection to an
unpainted, heavy metal part (i.e.
engine hook (3)) of the engine of the
vehicle with the discharged battery
(1).
4) If the booster battery you are using is
installed on another vehicle, start the
engine of the vehicle with the booster
battery. Run the engine at moderate
speed.
5) Start the engine of the vehicle with the
discharged battery.
6) Remove the jumper cables in the exact
reverse order in which you connected
them.
Towing a Disabled VehicleEmergency TowingIf your vehicle is disabled, it may be towed
by a tow truck using one of the following
methods:
1) Tow the vehicle with two wheels lifted
by the tow truck and the other two
wheels on a towing dolly.
2) Use the appropriate towing method
specified for your vehicle in the “Towing
Your Vehicle (recreational towing)” sec-
tion, but with the wheels lifted by the
tow truck instead of on a towing dolly.
Be sure to carefully follow the specific
instructions provided in the “Towing
Your Vehicle (recreational towing)” sec-
tion.
If the Starter Does Not
Operate1) Try turning the ignition switch to the
“START” position with the headlights
turned on to determine the battery con-
dition. If the headlights go excessively
dim or go off, it usually means that
either the battery has run down or bat-
tery terminal contact is poor. Recharge
the battery or correct battery terminal
contact if necessary.
2) If the headlights remain bright, check
the fuses. If the reason for failure of the
starter is not obvious, there may be a
major electrical problem. Have the vehi-
cle inspected by your authorized
SUZUKI dealer.
WARNING
Never connect the jumper cable
directly to the negative (–) terminal of
the discharged battery, or an explo-
sion may occur.
CAUTION
If vehicle damage (such as steering
or drivetrain damage, inability to
operate free axle mechanism, etc.)
prevent normal use of the towing pro-
cedures for your vehicle described in
the “Towing Your Vehicle (recre-
ational towing)” section, have your
vehicle towed with two wheels lifted
by the tow truck and the other two
wheels on a towing dolly.
