VEHICLE LOADING AND TOWING
54P00-01E
NOTE:
If your vehicle has a parking sensor sys-
tem, set the system to the trailer mode via
the information display. When this mode is
set, the rear corner and rear center sen-
sors are inhibited from operating. Refer to
“Information display” in “BEFORE DRIV-
ING” section.
To w b a r s
Only use a tow bar that is designed to
attach to the chassis of your vehicle, and a
hitch that is designed to bolt to this tow bar.
We recommend that you use a genuine
SUZUKI tow bar (available as option), or
equivalent.
Safety chains
Always attach safety chains between your
vehicle and trailer. Cross safety chains
under the nose of the trailer so that the
nose will not drop to the road if the trailer
becomes separated from the tow bar. Fol-
low 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 lights
Check that your trailer is equipped with
lights which meet local requirements.
Always check for the proper operation of
all trailer lights before you start to tow.
Brakes
WA R N I N G
For vehicles equipped with the radar
brake support system, if your vehicle
is used to tow a trailer, press the
radar brake support OFF switch and
turn off the radar brake support sys-
tem. If not, unexpected accidents
related to the system being turned on
may occur.
NOTICE
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.
WA R N I N G
Never use a tow bar which attaches
to the axle or the bumper of your
vehicle.
WA R N I N G
Never attach safety chains to the
bumper of your vehicle. Secure con-
nections so that they cannot come
loose.
WA R N I N G
Never connect trailer lights directly
into your vehicle’s electrical system,
or electrical system damage may
occur.
WA R N I N G
If trailer brakes are used, follow all
instructions provided by the manu-
facturer. Never connect to the brake
system of your vehicle and never
take an electrical supply directly from
the wiring harness.

Tires
Mirrors
Check if your vehicle’s mirrors meet local
requirements for mirrors used on towing
vehicles. If they do not, you must install the
required mirrors before you tow.
Vehicle/trailer loading
To load your vehicle and trailer properly,
you must know how to measure gross
trailer weight and trailer nose weight.
Gross trailer weight is the weight of the
trailer plus all the cargo in it. You can mea-
sure gross trailer weight by putting the fully
loaded trailer on a vehicle scale.
Nose weight is the downward force
exerted on the tow bar by the trailer cou-pler, with the trailer fully loaded and the
coupler at its normal towing height. This
weight can be measured using a bathroom
scale.
The weight of your loaded trailer (gross
trailer weight) should never exceed towing
capacity.
Distribute cargo in your trailer so that nose
weight is about 10% of gross trailer weight,
but does not exceed the maximum vertical
load on trailer hitch point. You should mea-
sure gross trailer weight and nose weight
before towing to check that your load is
properly distributed.
Additional trailer towing warnings
WA R N I N G
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 pressures listed on your vehicles
tire information label. If laden pres-
sures are listed on the label, the tires
should be inflated to the laden pres-
sures. Inflate trailer tires according to
the specifications provided by the
trailer manufacturer.
WA R N I N G
Improper weight distribution of your
trailer may result in poor vehicle han-
dling and swaying of the trailer.
Always check that trailer nose weight
is about 10% of gross trailer weight,
but does not exceed the maximum
vertical load on trailer hitch point.
Also check that the cargo is properly
secured. Failure to observe this
requirement may result in an acci-
dent.
WA R N I N G
Never overload cargo on your trailer
or your vehicle. Gross trailer weight
must never exceed towing capacity.
Gross vehicle weight (sum of the
weights of the vehicle, all the occu-
pants, accessories including tow
bars and a trailer hitch, cargo and
trailer nose weight) must never
exceed the Gross Vehicle Weight Rat-
ing (GVWR) listed in “SPECIFICA-
TIONS” section.
WA R N I N G
Connect trailer lights and hook up
safety chains every time you tow.
NOTICE
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 in
“Maintenance recommended under
severe driving conditions”.

INSPECTION AND MAINTENANCE
54P00-01E
If the coolant level is below “LOW” mark,
more coolant should be added. When the
engine is cool, remove the degassing tank
cap by turning it counterclockwise slowly to
release any pressure. And add coolant
until the degassing tank level reaches
“FULL” mark. Never fill the degassing tank
above “FULL” mark.
Coolant replacement
Since special procedures are required, ask
your authorized SUZUKI dealer for this job.
Air cleaner
If the air cleaner is clogged with dust, there
will be greater intake resistance, resulting
in decreased power output and increased
fuel consumption.
(For gasoline engine model)
61MM0B063
1) Remove the air cleaner inlet hose (1).
2) Remove the bolts (2), loosen the bolt
(3) and lift the air cleaner case (4)
directly above.
61MM0B064
3) Unclamp the side clamps, and remove
the element from the air cleaner case. If
it appears to be dirty, replace it with a
new one.
4) Clamp the side clamps or tighten the
bolts securely.
WA R N I N G
It is hazardous to remove the reser-
voir tank cap (degassing tank cap) for
a diesel engine when the water tem-
perature is high, because scalding
fluid and steam may be blown out
under pressure. Wait until the coolant
temperature has lowered before
removing the cap.
NOTICE
When lifting the air cleaner, check that
the air cleaner does not interfere with
the engine oil dipstick (5) to avoid
damage the dipstick.

Parking brake
54G109
Ratchet tooth specification “b”:
4th – 9th
Lever pull force (1):
200 N (20 kg, 45 lbs)
Check the parking brake for proper adjust-
ment by counting the number of clicks
made by the ratchet teeth as you slowly
pull up on the parking brake lever to the
point of full engagement. The parking
brake lever should stop between the speci-
fied ratchet teeth and the rear wheels
should be securely locked. If the parking
brake is not properly adjusted or the
brakes drag after the lever has been fully
released, have the parking brake inspected
and/or adjusted by your SUZUKI dealer.
Brake discs
If the measured thickness or inner diame-
ter of the most worn part exceeds the
value indicated above, the parts should be
replaced with a new one. The measure-
ment involves disassembling each brake
and requires the use of a micrometer,
which must be done according to the
instructions described in the relevant ser-
vice manual or available from the relevant
repair information site.
Steering
68LM708
Steering wheel play “c”:
0 – 30 mm (0.0 – 1.2 in.)
Check the play of the steering wheel by
gently turning it from left to right and mea-
suring the distance that it moves before
you feel slight resistance. The play should
be between the specified values.
Check that the steering wheel turns easily
and smoothly without rattling by turning it
all the way to the right and to the left while
driving very slowly in an open area. If the
amount of free play is not as specified or
you find anything else to be wrong, an
inspection must be performed by your
SUZUKI dealer.

Tire rotation
4-tire rotation
54G114
To avoid uneven wear of your tires and to
prolong their life, rotate the tires as illus-
trated. Tires should be rotated every 10000
km (6000 miles). After rotation, adjust front
and rear tire pressures to the specification
listed on your vehicle’s tire information
label.
NOTE:
(For Mexico)
For additional instruction, refer to “SUP-
PLEMENT” section in the end of this book.
Compact spare tire (if equipped)
54G115
(1) Wear indicator
(2) Indicator location mark
Your vehicle comes equipped with a com-
pact spare tire. It is designed to save
space in your storage area, and its lighter
weight facilitates installing the spare tire
when getting a flat tire. It is only intended
for temporary emergency use, until the
conventional tire can be repaired or
replaced. The inflation pressure of the
compact spare tire should be checked at
least once a month. Use a quality pocket-
type inflation pressure gauge and set at
420 kPa (60 psi). At the same time, check
that the tire is stored securely. If it is not,
tighten it.Note that two or more compact spare tires
should not be used on one vehicle simulta-
neously.
WA R N I N G
The compact spare tire and wheel are
intended for temporary emergency
use only. Continuous use of this
spare can result in tire failure and
loss of control. Always observe these
precautions when using this spare:
• Your vehicle should be handled in a
different way when using this
spare.
• Do not exceed 80 km/h (50 mph).
• Replace this spare with a standard
tire and wheel as soon as possible.
• Use of this spare will reduce
ground clearance.
• Recommended air pressure for this
spare is 420 kPa (60 psi).
• Do not use tire chains on the com-
pact spare. If you must use tire
chains, rearrange the wheels so
standard tires and wheels are fitted
to the front axle.
• The compact spare tire has a much
shorter tread life than the conven-
tional tires on your vehicle.
Replace the tire as soon as the
tread wear indicator appears.
• When replacing the compact spare
tire, use a replacement tire with the
exact same size and construction.
