WARNING
Each tire should be checked monthly when cold and inflated to the inflation pressure rec-
ommended 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 Infor-
mation placard, you should determine the proper tire inflation pressure for those tires. What to do if ...

* optional Z

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 increases energy consumption, reduces 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 incom-
patible 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. 174

tion of the tire repair kit in your vehicle
before sealing a tire.
The tire repair kit can be used to seal
punctures of up to approximately 0.16 in
(4 mm) on the tire tread.
The tire repair kit enables you to drive on
the sealed tire to the nearest authorized
electric drive smart center.
X You should have the sealed tire replaced
at an authorized electric drive smart
center. G
WARNING
Take care not to allow the contents of the
tire sealant to come in contact with hair,
eyes or clothing. The tire sealant is harm-
ful if inhaled, swallowed or absorbed
through the skin - causes skin, eye and res-
piratory irritation. Wear gloves while
using this product if they are available.
Any contact with eyes or skin should be
flushed immediately with plenty of water.
If clothing comes in contact with the tire
sealant, change clothing as soon as possi-
ble.
In case of allergic reaction or rash, consult
a physician immediately. Notes
R Small tire punctures, particularly those
in the tread, can be sealed with the tire
sealant.
R The tire sealant can be used in ambient
temperatures from ‑4 ¦(‑20¥) to
104¦ (+40¥).
R Do not remove any foreign objects such as
nails or screws that have penetrated the
tire.
R Do not use the tire sealant if the tire has
been damaged by being driven when
insufficiently inflated (e.g. bumps,
cuts, cracks etc. on the tire).
R Allow escaped tire sealant to dry, then
peel it off. R
Immediately wash all painted surfaces
that came into contact with the tire seal-
ant using a damp cloth.
R Avoid skin and eye contact with the tire
sealant.
R Do not swallow the tire sealant.
R Allow the tire sealant that is inside the
damaged tire to dry and dispose of
together with the tire.
R Do not use the tire sealant after the expi-
ration date has elapsed (see top of con-
tainer).
Instead, have it replaced at an author-
ized electric drive smart center. G
WARNING
The tire sealant is a limited repair device.
The tire sealant cannot be used for cuts or
punctures larger than approximately
0.16 in (4 mm) and tire damage caused by
driving with extremely low tire inflation
pressure, or on a flat tire, or a damaged
wheel.
Do not drive the vehicle under such cir-
cumstances.
If you are unsure of the condition of the tire
or have any question whatsoever about its
suitability for driving contact the nearest
authorized electric drive smart center for
assistance or call Roadside Assistance. G

Notes
! Only use tires which have been tested
and approved by smart. Tires approved by
smart are developed to provide best pos-
sible performance in conjunction with
the driving safety systems on your vehi-
cle 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 energy consumption
Moreover, tires and rims not approved by
smart may, under load, exhibit dimen-
sional 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 electric
drive 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 man-
ufacturer’s maintenance recommenda-
tion included with vehicle. Mobility
Your vehicle is equipped with a tire repair
kit (Y page 187). In case of a flat tire, it
