WARNING
When the ABS system is malfunctioning, the wheels may lock during hard braking, reducing steering capability and extending the braking distance.
When the ABS is switched off due to a malfunction, the ESP ®
is also switched off. The basic
driving and braking functions are still available.
The risk of your vehicle skidding is then increased in certain situations. You should
therefore always adapt your speed and driving style to the prevailing road and weather
conditions. Problem Possible causes/consequences and

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 tireor have any question whatsoever about its
suitability for driving contact the nearest
authorized electric drive smart center for
assistance or call Roadside Assistance. G
WARNING
Please review the instructions below for
using the tire repair kit. If you are not
confident that you can competently follow
the instructions for using this kit, do not
use the kit, but instead call for Roadside
Assistance. G
WARNING

dren. If swallowed, rinse mouth immedi-
ately with plenty of water and drink plenty of water.

Rims and tires
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
enables you to drive to the nearest author- ized electric drive smart center on the
sealed tire. If the tire is damaged too severely for the
tire sealant to provide a reliable tire
repair:
X Contact the nearest authorized electric
drive smart center.

WARNING
During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorption of moisture from the atmosphere. Under extremely
strenuous operating conditions, this mois-
ture content can lead to the formation of
bubbles in the system, thus reducing the
system’s efficiency.
Therefore, the brake fluid must be replaced regularly. Refer to your vehicle’s Mainte-
nance Booklet for replacement interval.
Only brake fluid approved by smart is rec- ommended. Any authorized electric drive
smart center will provide you with addi-
tional information. Windshield/rear window washer system
