GWarning!
Each tire should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the Tire and Loading Information placard. If
your vehicle has tires of a different size than the size indicated on the Tire and Loading
Information placard, 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 underinflated.
Accordingly, when the low tire pressure telltale illuminates, you should stop and check your
tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly
underinflated tire causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency 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
maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even
if underinflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS malfunction indicator is combined with the

low tire pressure telltale. When the system detects a malfunction, the telltale will flash for
approximately 1 minute and then remain continuously illuminated.
This sequence will continue upon subsequent vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is illuminated, the system may not be able to detect
or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation of
incompatible replacement 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.

Preparing the vehicle
Upon experiencing any type of problem
with the vehicle’s tires, switch on the
hazard warning flasher, carefully slow
down and exit the roadway in a cautious
manner.
XPark the vehicle at a safe distance from
moving traffic on a hard, flat surface
when possible.
XMake sure the tire valve of the damaged
tire is located below the horizontal axle
of the wheel hub.
XEngage the parking brake.XTurn the steering wheel so that the front
wheels are in a straight ahead position.
XMove the gear selector lever to park
position P.
XTurn off the engine.XRemove the key from the starter switch
and take the key with you.
iOpen door only when conditions are safe
to do so.
XHave any passenger exit the vehicle at a
safe distance from the roadway.
Using the tire repair kit
! Depending on the type of damage on the
tire, the tire sealant could damage the
sensor of the Tire Pressure Monitoring
System (TPMS)*. Such damage is not
covered by the smart Limited Warranty.
When having the damaged tire replaced,
also have the TPMS sensors* checked for
proper function. When the sensor is
damaged, the TPMS* will not function
properly. The sensor must then be
replaced at an authorized smart center as
soon as possible.
The tire repair kit can be used to seal
punctures of up to approximately 0.16 in
(4 mm) on the tire tread.

If tire inflation pressure has fallen below
130 kpa (1.3 bar, 20 psi) do not continue to
drive the vehicle.
Park your vehicle safely away from the
roadway and contact the nearest smart
center or call Roadside Assistance.
Have the damaged tire replaced.
XIf the tire inflation pressure is at least
130 kpa (1.3 bar, 20 psi), inflate or deflate
the tire to correct tire inflation
pressure (see Tire and Loading
Information placard located on the
driver’s door B‑pillar).
R To increase the tire inflation
pressure: Switch on the electric air
pump.
R To decrease the tire inflation
pressure: Open vent screw 008A. Recheck
the tire inflation pressure with the
electric air pump’s pressure gauge.XAfter checking the tire inflation
pressure, unscrew the end of filler
hose 0088 from tire valve 0072.XPlug filler hose with the stopper.XPlace the tire repair kit securely in the

! The manufacturer is unable to
guarantee that all tire punctures can be
repaired with the tire repair kit, in
particular cuts or perforations larger
than approximately 0.16 in (4 mm) or away
from the tire’s tread. The manufacturer
is not liable for damage sustained
through improper use of the tire repair
kit.GWarning!
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel
economy, and are more likely to fail from
being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
XDrive to the nearest authorized smart
center, to have the damaged tire
replaced.XContact an authorized smart center as
soon as possible to obtain a new filler
hose and a new tire sealant container.XBring used tire sealant materials to an
authorized smart center for proper
disposal.XReplace your tire sealant container
every 4 years. Replacement containers
are available at any authorized smart
center.GWarning!
After changing a tire, contact a smart
center to make sure the bolts holding the
wheel to the car are tight enough.
Otherwise, the wheels could come off. Each

Rims and tires
Notes
! Only use tires which have been tested
and approved by smart. Tires approved by
smart are developed to provide best
possible performance in conjunction
with the driving safety systems on your
vehicle such as the ABS or the ESP ®
.
Using tires other than those approved by
smart may result in damage that is not
covered by the smart Limited Warranty.
! Using tires other than those approved
by smart can have detrimental effects,
such as
R poor handling characteristics
R increased noise
R increased fuel consumption
Moreover, tires and rims not approved by
smart may, under load, exhibit
dimensional variations and different
tire deformation characteristics that
could cause them to come into contact
with the vehicle body or axle parts.
Damage to the tires or the vehicle may be
the result.
i Further information on tires and rims
is available at any authorized smart
center. A placard with the recommended
tire inflation pressure is located on the
driver’s door B‑pillar.
The tire inflation pressure should be
checked regularly and should only be
adjusted on cold tires. Follow tire
manufacturer’s maintenance
recommendation included with vehicle.
Mobility
Your vehicle is equipped with a tire repair
kit ( Y page 188). In case of a flat tire, it
enables you to drive to the nearest
