OPERATING YOUR VEHICLE
66J22-03E
How the ABS WorksA computer continuously monitors wheel
speed. The computer compares the
changes in wheel speed when braking. If
the wheels slow suddenly, indicating a
skidding situation, the computer will
change braking pressure several times
each second to prevent the wheels from
locking. When you start your vehicle or
when you accelerate after a hard stop, you
may hear a momentary motor or clicking
sound as the system resets or checks
itself.
Electronic Stability Program
(ESP
®)
ESP
® is a registered trademark of
DaimlerChrysler AG.
The Electronic Stability Program (ESP
®)
helps to control the vehicle during corner-
ing if the vehicle is understeering or over-
steering. It also assists you in maintaining
traction while accelerating on loose or slip-
pery road surfaces. It does this by regulat-
ing the engine’s output, and by selectively
applying the brakes. In addition, ESP®
helps to avoid skidding by controlling brak-
ing pressure.The ESP
® has the following three systems:
Stability Control SystemThe vehicle stability control system helps
provide integrated control of systems such
as anti-lock brakes, traction control, engine
control, etc. This system automatically
controls the brakes and engine to help pre-
vent the vehicle from skidding when cor-
nering on a slippery road surface or when
turning the steering wheel abruptly.Traction Control SystemThe traction control system automatically
helps prevent the spinning of wheels when
the vehicle is started or accelerated on
slippery road surfaces. The system oper-
ates only if it senses that some of the
wheels are spinning or beginning to lose
traction. When this happens, the system
operates the front or rear brakes and
reduces engine power to limit wheel spin.
NOTE:
You may hear a clicking sound in the
engine compartment for a few seconds
when you start the engine or just after the
vehicle begins to move. This means that
the above systems are in the self-check
mode. This sound does not indicate a mal-
function.
WARNING
The ABS may not work properly if
tires or wheels other than those
specified in the owner’s manual are
used. This is because the ABS works
by comparing changes in wheel
speed. When replacing tires or
wheels, use only the size and type
specified in this owner’s manual.
WARNING
The ESP
® cannot enhance the vehi-
cle’s driving stability in all situations
and does not control your vehicle’s
entire braking system. The ESP
® can-
not prevent accidents, including
those resulting from excessive speed
in turns, or hydroplaning. Only a safe
and attentive driver can prevent acci-
dents. The capabilities of an ESP
®-
equipped vehicle must never be used
as a substitute for careful driving.

6-19OPERATING YOUR VEHICLE
66J22-03E
Anti-Lock Braking System (ABS)ABS will help you avoid skidding by elec-
tronically controlling braking pressure. It
will also help you maintain steering control
when braking on slippery surfaces or when
braking hard. The ABS works automati-
cally, so you do not have to use any special
braking technique. Just push the brake
pedal down without pumping. The ABS will
operate whenever it senses that wheels
are locking up. You may feel the brake
pedal pulsate while the ABS is operating.
(For more information on ABS, see “Brak-
ing” in the “OPERATING YOUR VEHICLE”
section.)
NOTE:
If the ABS system is activated, you may
hear a clunking noise and/or feel pulsating
in the brake pedal. This is normal and indi-
cates that the brake fluid pressure is being
controlled properly.The ESP
® indicator lights are described
below:
SLIP Indicator Light
66J033
When one of the ESP
® systems other than
ABS is activated, the SLIP indicator light in
the instrument cluster blinks 5 times per
second.
NOTE:
When the SLIP indicator light comes on
and stays on while driving, indicating a
malfunction of the ESP® systems (other
than ABS), the brake system will function
as an ordinary ABS with no additional
ESP
® functions.
WARNING
 The ESP
® may not work properly if
tires or wheels other than those
specified in the Owner’s Manual are
used. When replacing tires or
wheels, use only the size and type
specified in this Owner’s Manual.
 The ESP® may not work properly if
tires are not inflated to the recom-
mended tire inflation pressure.
 The ESP® may not work properly if
tires are fitted with tire chains.
 The ESP® may not work properly if
the tires are excessively worn. Be
sure to replace tires when the tread
wear indicators in the grooves
appear on the tread surface.
 The ESP® is not a substitute for
winter tires or tire chains on a snow
covered road.
WARNING
 The ESP
® may not work properly if
engine related parts such as the
muffler are not equivalent to stan-
dard equipment or are extremely
deteriorated.
 Do not modify the vehicle’s sus-
pension since the ESP
® may not
operate correctly.
CAUTION
If the SLIP indicator light comes on
and stays on while driving, there may
be a malfunction of the ESP
® sys-
tems (other than ABS). You should
have the systems inspected by an
authorized SUZUKI dealer.

traction, and the “ESP OFF” indicator
light will come on.
When the transfer switch (if equipped) is
turned to the “4L LOCK” position, brake-
traction control can be activated. Brake-
traction control brakes the spinning
wheel to distribute drive power to the
other wheels for increased climbing abil-
ity or for better performance on a rolling
hill or a slippery surface.
 If the ESP
® systems operate continu-
ously, such as when driving on slippery
roads, the traction control functions of
the ESP
® systems may be canceled
temporarily to avoid overheating the
brake pads, and the “ESP OFF” indicator
light will come on. After a short period of
time, the ESP
® systems (other than
ABS) will turn on automatically and the
“ESP OFF” indicator light will go out.
ABS Warning Light / Brake System
Warning LightSee “Braking” in the “OPERATING YOUR
VEHICLE” section.
Tire Pressure Monitoring
System (TPMS) (if equipped)The tire pressure monitoring system is
designed to alert you when one or more of
the tires on your vehicle is significantly
under-inflated. A Tire Pressure Monitoring
System (TPMS) sensor containing a
unique identification code is mounted on
each wheel. The TPMS sensors transmit
tire pressure signals to a central receiver
which relays the information to a tire pres-
sure monitoring system controller. When
the inflation pressure of one or more tires
indicates significant under-inflation, the low
tire pressure warning light shown below
comes on.
NOTE:
The TPMS controller is not programmed to
recognize the ID code of the TPMS sensor
in your spare tire. The tire pressure moni-
toring system will only work with the spare
tire if you bring your vehicle to an autho-
rized SUZUKI dealer to register the ID
code of the spare tire sensor. Refer to
“Replacing Tires and/or Wheels” in this
section.
Low Tire Pressure Warning Light
52D305
WARNING
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.

66J22-03E
Tire ChainsTire chains should only be used if they are
needed to increase traction or are required
by law. Make sure that the chains you use
are small-link chains or cable-type chains
and are the correct size for your vehicle’s
tires. Also make sure that there is enough
clearance between the fenders and the
chains as installed on the tires.
Install the chains on the rear tires tightly,
according to the chain manufacturer’s
instructions. Retighten the chains after
driving about 1.0 km (1/2 mile) if neces-
sary. With the chains installed, drive slowly.Do not drive through deep or rushing
water
Driving in deep or rushing water can be
hazardous. You could lose control of the
vehicle and the occupants could drown.
Also, your vehicle could be seriously dam-
aged. To avoid these risks, observe the fol-
lowing instructions and precautions.
 Do not drive through deep or rushing
water. Deep or rushing water, such as
fast-moving streams or floodwaters,
could carry your vehicle away from your
intended path. The water is too deep if it
covers your wheel hubs, axles or
exhaust tailpipe. Know the depth of the
water before you attempt to drive
through it.
 If water blocks the tailpipe, the engine
may not start or run. If the water is deep
enough to get drawn into the engine
intake system, the engine will be badly
damaged.
 Submerged brakes will have poor brak-
ing performance. Drive slowly and care-
fully. Driving slowly will also help avoid
water splashing onto the ignition system,
which could cause the engine to stall.
 Even when driving through shallow or
still waters, drive carefully since the
water may be hiding ground hazards
such as holes, ditches or bumps.
WARNING
 Do not allow anyone to stand near
the vehicle when you are rocking it,
and do not spin the wheels faster
than an indicated 40 km/h (25 mph)
on the speedometer. Personal
injury and/or vehicle damage may
result from spinning the wheels too
fast.
 Be sure to turn the transfer switch
from “4H” to “4H LOCK” or “4L
LOCK” when the tires slip in “4H”.
The continuing tires slip in “4H”
can cause the limited slip differen-
tial gear damage in the center dif-
ferential.
CAUTION
Release the accelerator pedal when
operating the gearshift lever. Operat-
ing the lever with the engine racing
can damage the gears.
CAUTION
Do not continue rocking the vehicle
for more than a few minutes. Pro-
longed rocking can cause engine
overheating, transmission or trans-
fer case damage or tire damage.
CAUTION
If you hear the chains hitting against
the vehicle body while driving, stop
and tighten them.
Off-Road Driving: NO

DRIVING TIPS
66J22-03E
WARNING
In addition to following the driving
tips in this section, it is important to
observe the following precautions for
on-road and off-road driving.
 Driver and passengers should wear
seat belts at all times.
 Do not let anyone else drive your
vehicle unless they are also aware
of the vehicle characteristics and
handling differences described in
this section.
 Avoid loaning your vehicle to any-
one unless you accompany them.
 Make sure your tires are in good
condition and always maintain the
specified tire pressure. Refer to
“Tires” in the “INSPECTION AND
MAINTENANCE” section for
details.
 Do not use tires other than those
specified by SUZUKI. Never use dif-
ferent sizes or types of tires on the
front and rear wheels. For informa-
tion regarding the specified tires,
refer to the Tire Inflation Pressure
Label located on the driver’s side
door pillar or the “SPECIFICA-
TIONS” section.
(Continued)
WARNING
(Continued)
 Never use oversized tires or special
shocks and springs to raise (jack
up) your vehicle. This will raise the
center of gravity of the vehicle and
change its handling characteris-
tics. Oversized tires may also rub
against the fender over bumps,
causing vehicle damage or tire fail-
ure.
 After driving through water, mud or
sandy ground, test the brakes while
driving at a slow speed to see if
they have maintained their normal
effectiveness. If the brakes are less
effective than normal, dry them by
repeatedly applying the brakes
while driving slowly until the
brakes have regained their normal
effectiveness.
 Do not use “4H LOCK” or “4L
LOCK” drive for normal driving.
 After extended operation in mud,
sand or water, have the brakes
inspected by your authorized
SUZUKI dealer as soon as possi-
ble.

C. Tire Size
The tire size code is a combination of
letters and numbers used to define a
particular tire’s width, height, aspect
ratio, construction type, and service
description. See the “Tire Size” expla-
nation later in this section for more
details.
D. U.S. DOT Tire Identification Number
The Department of Transportation
(DOT) marking indicates that the tire
is in compliance with the U.S. Depart-
ment of Transportation Motor Vehicle
Safety Standards. The letters and
numbers following the DOT marking
is the Tire Identification Number
(TIN). The TIN identifies the tire man-
ufacturer 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 support in normal
service.
G. Max Inflation Pressure
Max inflation pressure is the maxi-
mum inflation pressure a tire is
designed for.
H. Tire Ply Material
These tire markings describe the typeof 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 carry-
ing 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.)
*The letters ZR may be used on tires with a
maximum speed capability over 149 mph
and will always be used on tires with a
maximum speed capability over 186 mph.J. M+S Marking
This marking indicates the tire has
some mud and snow capabilities and
is designed for all-season use.

D. Construction Code
This letter code is used to indicate the
type of ply construction in the tire. The
letter “R” means radial ply tire con-
struction, the letter “D” means diago-
nal or bias ply construction, and the
letter “B” means belted-bias ply con-
struction.
E. Rim Diameter
This two-digit number is the wheel or
rim diameter in inches.
Tire Inflation PressureTire inflation pressure should be checked
when the tire is cold. “Cold tire inflation
pressure” is the pressure in a tire that has
been driven less than 1 mile (1.6 km) or
has been standing for three hours or more.
54G307
The front, rear and spare tire pressure
specifications for your vehicle are shown
below and are listed on the Tire and Load-
ing Information Label, which is located on
the driver’s door lock pillar. The Tire and
Loading Information Label contains the fol-
lowing information:
 Seating Capacity
 Maximum Allowed Combined Weight of
Occupants and Cargo
 Original Tire Size
 Recommended Cold Tire Inflation Pres-
sure of Original TiresNOTE:
The tire inflation pressure will change due
to changes in atmospheric pressure, tem-
perature or tire temperature when driving.
To reduce the chance that the low tire
pressure warning light will come on due to
normal changes in temperature and atmo-
spheric pressure, it is important to check
and adjust the tire pressures when the
tires are cold. Tires that appear to be at the
specified pressure when checked after
driving, when the tires are warm, could
have pressure below the specification
when the tires cool down. Also, tires that
are inflated to the specified pressure in a
warm garage may have pressure below the
specification when the vehicle is driven
outside in very cold temperature. If you
adjust the tire pressure in a garage that is
warmer than the outside temperature, you
should add 1 psi to the recommended cold
tire inflation pressure for every 10°F differ-
ence between garage temperature and
outside temperature.
WARNING
Your SUZUKI is equipped with tires
which are all the same type and size.
This is important to ensure proper
steering and handling of the vehicle.
Never mix tires of different size or
type on the four wheels of your vehi-
cle. Mixing tires could cause you to
lose control while driving which may
lead to an accident. The size and type
of tires used should be only those
approved by SUZUKI Motor Corpora-
tion as standard or optional equip-
ment for your vehicle.

show abnormal wear, have them
inspected by your SUZUKI dealer.
4) Check for loose wheel nuts.
5) Check that there are no nails, stones or
other objects sticking into the tires.
Uniform Tire Quality GradingThe U.S. National Highway Traffic Safety
Administration has developed a grading
system for evaluating the performance of
passenger car tires. The following informa-
tion will help you understand the grading
system, which applies to vehicles sold in
the U.S. Consult your SUZUKI dealer or
tire retailer for help in choosing the correct
replacement tires for your vehicle.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature ADOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B CAll Passenger Car Tires Must Conform To
Federal Safety Requirements in Addition
To These Grades
Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For
example, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however and may depart significantly from
WARNING
Hitting curbs and running over rocks
can damage tires and affect wheel
alignment. Be sure to have tires and
wheel alignment checked periodically
by your SUZUKI dealer.
WARNING
Your SUZUKI is equipped with tires
which are all the same type and size.
This is important to ensure proper
steering and handling of the vehicle.
Never mix tires of different size or
type on the four wheels of your vehi-
cle. The size and type of tires used
should be only those approved by
SUZUKI Motor Corporation as stan-
dard or optional equipment for your
vehicle.
WARNING
Replacing the wheels and tires
equipped on your vehicle with certain
combinations of aftermarket wheels
and tires can significantly change the
steering and handling characteris-
tics of your vehicle. Oversized tires
may also rub against the fender over
bumps, causing vehicle damage or
tire failure. Therefore, use only those
wheel and tire combinations
approved by SUZUKI Motor Corpora-
tion as standard or optional equip-
ment for your vehicle. For
information regarding the specified
tires, refer to the Tire Information
Label located on the driver’s side
door pillar or the “SPECIFICATIONS”
section.
CAUTION
Replacing the original tires with tires
of a different size may result in false
speedometer or odometer readings.
Check with your SUZUKI dealer
before purchasing replacement tires
that differ in size from the original
tires.
