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.
WARNING
If the low tire pressure warning light
comes on and stays on, reduce your
speed and avoid abrupt steering and
braking. Stop in a safe place as soon
as possible and check your tires.
 If you have a flat tire, replace it with
the spare tire. Refer to “Jacking
Instructions” in the “EMERGENCY
SERVICE” section. Refer to
“Replacing Tires and/or Wheels”
for instructions on how to restore
normal operation of the tire pres-
sure monitoring system after you
have had a flat tire.
 If one or more of your tires is
under-inflated adjust the inflation
pressure in all of your tires to the
recommended inflation pressure as
soon as possible.
Be aware that driving on a signifi-
cantly under-inflated tire can cause
the tire to overheat and can lead to
tire failure, and may affect steering
control and brake effectiveness. This
could lead to an accident, resulting in
severe injury or death.

OPERATING YOUR VEHICLE
80J23-03E
The low tire pressure warning light can
come on due to normal causes such as
natural air leaks and pressure changes
caused by changes in temperature or
atmospheric pressure. Adjusting the air
pressure in the tires to the pressure shown
on the tire information placard should
cause the low tire pressure warning light to
turn off.
If the light turns on again shortly after
adjusting the pressure in your tires, you
may have a flat tire. If you have a flat tire,
replace it with the spare tire. Refer to
“Jacking Instructions” in the “EMER-
GENCY SERVICE” section. Refer to
“Replacing Tires and/or Wheels” for
instructions on how to restore normal oper-
ation of the tire pressure monitoring sys-
tem after you have had a flat tire.
NOTE:
 When the tire inflation pressure is
adjusted in high altitude areas, the low
tire pressure light may not turn off even
after tire inflation pressure adjustment.
In this case, adjust the inflation pressure
to a slightly higher pressure than is
shown on the tire information placard.
 The low tire pressure warning light may
turn off temporarily after coming on. This
could be due to surface temperature
increases after long distance driving or
traveling to a high temperature area.
Even if the tire pressure warning lightturns off after coming on, make sure to
check the inflation pressure of all tires.
 To reduce the chance that the low tire
pressure warning light will come on due
to normal changes in temperature and
atmospheric 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 specifica-
tion 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
difference between garage temperature
and outside temperature.
For tire inflation pressure information, refer
to “Tire Inflation Pressure” in the “INSPEC-
TION AND MAINTENANCE” section.
TPMS Malfunction Indicator
WARNING
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not oper-
ating properly.
WARNING
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long
as the malfunction exists.

3-29OPERATING YOUR VEHICLE
80J23-03E
When you turn off the engine, however, the
malfunction indicator resets. It takes about
ten minutes after restarting the engine for
the malfunction to be detected again and
for the light to start flashing.
TPMS LimitationsThe tire pressure monitoring system may
not function properly under certain circum-
stances. In the following situations, the low
tire pressure warning light may come on
and remain on or may blink.
 When you replace a flat tire with the
spare tire.
 When you include the spare tire during a
tire rotation.
 When the TPMS sensor is damaged dur-
ing a tire replacement or liquid sealants
are used to repair a flat tire. When the TPMS sensor’s electronic sig-
nal is disturbed in one of the following
ways:
– Electric devices or facilities using simi-
lar radio wave frequencies are nearby.
– A lot of snow or ice covers the vehicle,
in particular, around the wheels or
wheel housings.
– Snow tires or tire chains are used.
 When you use non-genuine SUZUKI
wheels or tires.
Replacing Tires and/or WheelsIf you get a flat tire, Suzuki recommends
that you have an authorized SUZUKI
dealer mount a new tire on the wheel that
had the flat tire, and reinstall this tire on the
vehicle in place of the spare. The TPMS is
already set up to recognize the ID code of
the original wheel, and normal TPMS oper-
ation will be restored.
If you need to replace original wheels on
your vehicle, your dealer must make sure
that TPMS sensors are installed in the new
wheels and must set up the TPMS to rec-
ognize the new sensors.
NOTE:
A TPMS sensor is not installed in the spare
tire. You should use the spare tire only in
an emergency situation, and should
replace the spare tire as soon as possible
to restore normal TPMS operation.
WARNING
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunctions
may occur for a variety of reasons,
including the installation of replace-
ment or alternate tires or wheels on
the vehicle that prevent the TPMS
from functioning properly. Always
check the TPMS malfunction telltale
after replacing one or more tires or
wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
CAUTION
 The tire pressure sensors can be
damaged by the installation or
removal of tires. When tires must
be repaired or replaced, we highly
recommend that you have them
repaired or replaced by an autho-
rized SUZUKI dealer.
 Do not use liquid sealants for a flat
tire as air pressure sensors can be
damaged.
 If the low tire pressure warning
light comes on frequently, there
may be something wrong with one
of the tires or with the monitoring
system. Have your vehicle
inspected by an authorized SUZUKI
dealer.

4-3DRIVING TIPS
80J23-03E
60A183S
Keep the air cleaner clean
If the air cleaner is clogged with dust, there
will be greater intake resistance, resulting
in decreased power output and increased
fuel consumption.
Keep weight to a minimum
The heavier the load, the more fuel the
vehicle consumes. Take out any luggage
or cargo when it is not necessary.
Keep tire pressure correct
Underinflation of the tires can waste fuel
due to increased running resistance of the
tires. Keep your tires inflated to the correct
pressure shown on the label located below
the driver’s side door latch striker.
Highway DrivingWhen driving at highway speeds, pay
attention to the following:
 Stopping distance progressively
increases with vehicle speed. Apply the
brakes far enough ahead of the stopping
point to allow for the extra stopping dis-
tance.
 On rainy days, “Hydroplaning” can occur.
“Hydroplaning” is the loss of direct con-
tact between the road surface and the
vehicle’s tires due to a water film forming
between them. Steering or braking the
vehicle while “Hydroplaning” can be very
difficult, and loss of control can occur.
Keep speed down when the road surface
is wet.
 At high speeds, the vehicle may be
affected by side winds. Therefore,
reduce speed and be prepared for unex-
pected buffeting, which can occur at the
exits of tunnels, when passing by a cut of
a hill, or when being overtaken by large
vehicles, etc.
Driving on Hills
80J2066
 When climbing steep hills, the car may
begin to slow down and show a lack of
power. If this happens, you should shift
to a lower gear so that the engine will
again be operating in its normal power
range. Shift rapidly to prevent the car
from losing momentum.
 When driving down a hill, the engine
should be used for braking by shifting to
next lower gear. (Do this with EITHER a
CVT or manual transaxle.)

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.

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.

WARNING
Your SUZUKI is equipped with
tires which are all the same type
and size. This is important to
ensure proper steering and han-
dling of the vehicle. Never mix
tires of different size or type on
the four wheels of your vehicle.
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 Corporation as standard or
optional equipment for your vehi-
cle.

80J23-03E
NOTE:
The tire inflation pressure will change
due to changes in atmospheric pres-
sure, temperature or tire temperature
when driving. To reduce the chance that
the low tire pressure warning light will
come on due to normal changes in tem-
perature and atmospheric pressure, it is
important to check and adjust the tire
pressures when the tires are cold. Tires
that appear to be at the specified pres-
sure 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 tempera-
ture, you should add 1 psi to the recom-
mended cold tire inflation pressure for
every 10°F difference between garage
temperature and outside temperature.Measuring Air Pressure
Use the following steps to achieve
proper tire inflation:
1) Identify the recommended tire pres-
sure on the vehicle’s Tire and Load-
ing Information Label or in the
owner’s manual.
2) Remove the valve cap from the tire
valve stem.
3) Using a reliable pressure gauge,
measure the tire inflation pressure
by pressing 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 cor-
rect pressure.
5) If the air pressure is too low, fill the
tire with air at a service station until
it reaches the recommended pres-
sure.
6) Make sure all tires have the same
air pressure (unless the owner’s
manual indicates otherwise).
WARNING
 Air pressures should be
checked when the tires are cold
or you may get inaccurate read-
ings.
 Check the inflation pressure
from time to time while inflating
the tire gradually, until the spec-
ified pressure is obtained.
 Never underinflate or overin-
flate the tires.
Underinflation can cause
unusual handling characteristics
or can cause the rim to slip on
the tire bead, resulting in an acci-
dent 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.
