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.

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.)

10-3GENERAL INFORMATION
79K21-03E
On-Board Vehicle Computers
and Event Data RecordersYour vehicle is equipped with on-board
computer systems which monitor and
control several aspects of vehicle per-
formance, including the following:
 Emission-related components and
engine parameters such as engine
speed and throttle position are moni-
tored to provide emissions control
and to provide optimum fuel econ-
omy. Your vehicle also has an on-
board diagnostic system which mon-
itors and records information about
emission-related malfunctions.
 Signals from various sensors are
monitored to provide air bag deploy-
ment.
 If your vehicle is equipped with
antilock brakes, conditions such as
vehicle speed and brake perfor-
mance are monitored, so that the
ABS system can provide effective
antilock braking. If your vehicle has
an Electronic Stability Program
(ESP
®) system, conditions such as
yaw rate, lateral acceleration, and
brake fluid pressure are monitored,
so that the ESP
® system can help
the driver control the vehicle in diffi-
cult driving situations.
Some information may be stored by
the on-board computers during normaloperation of the vehicle. This stored
information can assist technicians in
repairing the vehicle when malfunc-
tions occur. Other information is stored
only in the event of crash, by computer
systems that are commonly called
Event Data Recorders (EDRs).
In a crash event, EDRs such as the
Airbag Sensing and Diagnostic Mod-
ule (SDM) in your vehicle may record
information about the condition of the
vehicle and how it was operated, such
as data related to airbag readiness,
airbag performance, safety belt usage,
and the severity of the collision. These
data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur and lead to
the designing of safer vehicles. The
SDM in your vehicle does not collect
or store personal information.
To read the stored information, special
equipment is needed and access to
the vehicle or storage device is
required. SUZUKI will not access infor-
mation about a crash event or share it
with others other than with the consent
of the vehicle owner or lessee, in
response to an official request from
the police or similar government office,
as part of SUZUKI’s defense of litiga-
tion through the discovery process, or
as required by law.In addition, once SUZUKI collects or
receives data, SUZUKI may use the
data for research conducted by
SUZUKI, make the data available for
outside research if need is shown and
confidentiality is assured, or make
summary data which does not identify
specific vehicles available for outside
research.
Others, such as law enforcement per-
sonnel, may have access to the spe-
cial equipment that can read the
information if they have access to the
vehicle or storage device.
