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
noise as the system resets or checks itself.
Electronic Stability Program
(ESP
®) (if equipped)
ESP
® is a registered trademark of Daimler
AG.
The Electronic Stability Program (ESP
®)
helps to control the vehicle during corner-
ing if front wheels or rear wheels skid. It
also assists you in maintaining traction
while accelerating on loose or slippery
road surfaces. It does this by regulating the
engine’s output, and by selectively apply-
ing the brakes. In addition, ESP
® helps to
avoid skidding by controlling braking pres-
sure.
WARNING
If the ABS warning light ((1) or (2))
and the Brake system warning light
(3) on the instrument panel simulta-
neously stay on or come on when
driving, both anti-lock function and
rear brake force control function (pro-
portioning valve function) of the ABS
system may have failed. This could
cause the rear wheels to skid or the
vehicle to spin during braking on a
slippery road or hard braking on a
dry paved road. If both warning lights
come on, drive carefully, avoiding
hard braking as much as possible,
and ask your SUZUKI dealer to
inspect the ABS system immediately.
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.

OPERATING YOUR VEHICLE
80J23-03E
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.
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.
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.

Warning LightSee “Braking” in the “OPERATING YOUR
VEHICLE” section.
Tire Pressure Monitoring
System (TPMS)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.
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.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure.

4-5DRIVING TIPS
80J23-03E
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 front 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.
54G638S
CAUTION
Do not continue rocking the vehicle
for more than a few minutes. Pro-
longed rocking can cause engine
overheating, transaxle or transfer
case damage or tire damage.
CAUTION
If you hear the chains hitting against
the vehicle body while driving, stop
and tighten them.
If your vehicle is equipped with full
wheel caps, remove the wheel caps
before installing the chains or the
wheel caps can be damaged by the
chain bands.

DRIVING TIPS
80J23-03E
WARNING
In addition to following the driving
tips in this section, it is important to
observe the following precautions.
 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 Information Label
located on the driver’s side door
pillar.
 Never use oversized tires or special
shocks and springs to raise (jack
up) your vehicle. This will change
its handling characteristics. Over-
sized tires may also rub against the
fender over bumps, causing vehicle
damage or tire failure.
(Continued)
WARNING
(Continued)
 After driving through water, test the
brakes while driving at a slow
speed to see if they have main-
tained 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 effective-
ness.
