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.
WARNING
If the ABS warning light ((1) or (2)) on
the instrument panel comes on and
stays on while driving, there may be a
problem with the ABS system.
If this happens:
1) Pull off the road and stop care-
fully.
2) Turn the ignition switch to “LOCK”
and then start the engine again.
If the warning light comes on briefly
then turns off, the system is normal.
If the warning light still stays on,
have the system inspected by your
SUZUKI dealer immediately. If the
ABS system becomes inoperative,
the brake system will function as an
ordinary brake system that has no
ABS.
or
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
(Proportioning 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, avoid-
ing hard braking as much as possi-
ble, and ask your SUZUKI dealer to
inspect the ABS system immediately.
(1) (2)
(3)or
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.

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.NOTE:
When you disconnect and re-connect the
battery, ESP
® system functions other than
ABS will be deactivated and the slip indica-
tor light will blink 1 time per second. In this
case, use the following procedure to re-
activate the ESP
® systems:
1) Drive your vehicle straight ahead with-
out tire slippage at a speed until the slip
indicator is turned off. (Drive straight for
approximately 35 km/h (22 mph) or
more and 10 seconds or more.)
2) The slip indicator light will go out and
the ESP
® systems (other than ABS) will
be re-activated.
It may take more than few seconds before
the slip indicator light goes out depending
on the road surface condition.
“ESP” Warning Light
66J031
When the ESP
® systems (other than ABS)
have a system malfunction, the “ESP”
warning light in the instrument cluster
comes on.
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.

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.
(Continued)
WARNING
(Continued)
Driving on a significantly under-
inflated tire causes the tire to over-
heat and can lead to tire failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire
pressure, even if under-inflation has
not reached the level to trigger illumi-
nation of the TPMS low tire pressure
telltale.
WARNING
The tire pressure monitoring system
is not a substitute for regular tire
pressure inspections. Check tire
inflation pressures monthly when
cold and set to the recommended
inflation pressure as specified on the
vehicle’s tire information placard and
in the owner’s manual. Refer to
“Tires” in the “INSPECTION AND
MAINTENANCE” section.
WARNING
If the low tire pressure warning light
does not come on when the ignition
is turned to the “ON” position, or
comes on and blinks while driving
there may be a problem with the tire
pressure monitoring system. Have
your vehicle inspected by an autho-
rized SUZUKI dealer. Even if the light
turns off after blinking, indicating
that the monitoring system has
recovered, make sure to have an
authorized SUZUKI dealer check the
system.
WARNING
The load rating of your tires is
reduced at lower inflation pressures.
If your tires become even moderately
under-inflated, the vehicle load may
exceed the load rating of the tires,
which can lead to tire failure. The low
tire pressure warning light will not
alert you of this condition. The warn-
ing light will only come on when one
or more of your tires become signifi-
cantly under-inflated. Check and
adjust your tire inflation pressure at
least once a month. Refer to “Tires”
in the “INSPECTION AND MAINTE-
NANCE” section.

7-3DRIVING TIPS
80J21-03E
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.
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.

WARNING
(Continued)
 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.
 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.

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.

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.
80JS025
The front and rear tire pressure specifica-
tions for your vehicle are shown below and
are listed on the Tire and Loading Informa-
tion Label, which is located on the driver’s
door lock pillar. The Tire and Loading Infor-
mation Label contains the following infor-
mation:
 Seating Capacity
 Maximum Allowed Combined Weight of
Occupants and Cargo
 Original Tire Size
 Recommended Cold Tire Inflation Pres-
sure of Original Tires
 Size of Compact Spare Tire Recommended Cold Tire Inflation Pres-
sure of Compact Spare Tire
NOTE:
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.
Measuring Air Pressure
Use the following steps to achieve proper
tire inflation:
1) Identify the recommended tire pressure
on the vehicle’s Tire and Loading Infor-
mation Label or in the owner’s manual.
2) Remove the valve cap from the tire
valve stem.
3) Using a reliable pressure gauge, mea-
sure the tire inflation pressure by press-
ing the tire gauge firmly onto the valve
to get a pressure measurement.
Remember that inflation pressures
should be checked when the tires are
“cold”, meaning before they have been
driven one mile or after sitting for three
hours or more allowing the tire to cool
to ambient air temperature.
4) If the air pressure is too high, slowly
release the air by pressing on the tire
valve stem with the edge of the tire
gauge until you reach the correct pres-
sure.
5) If the air pressure is too low, fill the tire
with air at a service station until it
reaches the recommended pressure.
6) Make sure all tires have the same air
pressure (unless the owner’s manual
indicates otherwise).

Tire InspectionInspect your vehicle’s tires at least once a
month by performing the following checks:
1) Measure the air pressure with a tire
gauge. Adjust the pressure if neces-
sary. Remember to check the spare
tire, too. Refer to the “Measuring Air
Pressure” section.

(1) Tread wear indicator
(2) Indicator location mark
2) Check that the depth of the tread
groove is more than 1.6 mm (0.06 in.).
To help you check this, the tires have
molded-in tread wear indicators in the
grooves. When the indicators appear
on the tread surface, the remaining
depth of the tread is 1.6 mm (0.06 in.)
or less and the tire should be replaced.
3) Check for abnormal wear, cracks and
damage. Any tires with cracks or otherdamage should be replaced. If any tires
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.
WARNING
 Air pressures should be checked
when the tires are cold or you may
get inaccurate readings.
 Check the inflation pressure from
time to time while inflating the tire
gradually, until the specified pres-
sure is obtained.
 Never underinflate or overinflate
the tires.
Underinflation can cause unusual
handling characteristics or can
cause the rim to slip on the tire
bead, resulting in an accident or
damage to the tire or rim.
Underinflation can also cause tires
to overheat, leading to tire failure.
Overinflation can cause the tire to
burst, resulting in personal injury.
Overinflation can also cause
unusual handling characteristics
which may result in an accident.
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.

80J21-03E
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 GradesTreadwear
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
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to low-
est, are AA, A, B and C. Those grades rep-
resent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.
CAUTION
For intelligent All Wheel Drive (i-
AWD) models, replacing a tire with
one of a different size, or using differ-
ent brands among the four tires can
result in damage to the drive train.
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.
WARNING
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not
include acceleration, cornering,
hydroplaning or peak traction charac-
teristics.
