265 Preparing the vehicle
Upon experiencing any type of problem with
the vehicle's tires, switch on the hazard warn
ing flasher, carefully slow down and exit the
roadway in a cautious manner.
>Park the vehicle at a safe distance from
moving traffic on a hard, flat surface when
possible
.
>Set the parking brake.
>Turn the steering wheel so that the front
wheels are in a straight ahead position.
>Move the gear selector lever to park
positionP.
>Turn off the engine.
>Remove the key from the starter switch and
take the key with you.i
Open door only when conditions are safe to
do so.
>Have any passenger exit the vehicle at a
safe distance from the roadway.
Using the tire repair kitThe tire repair kit can be used to seal punc
tures 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 smart
center.
>You should have the sealed tire replaced at
an authorized 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
harmful if inhaled, swallowed or absorbed
through the skin it may causes skin, eye
and respiratory irritation. Wear gloves
while using this product if they are avail
able.
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 pos
sible.
In case of allergic reaction or rash,
consult a physician immediately.

Notes• Small tire punctures, particularly those in
the tread, can be sealed with the tire seal
ant.
• The tire sealant can be used in ambient
temperatures from 4°F (20°C) to +104°F
(+40°C).
• Do not remove any foreign objects such as
nails or screws that have penetrated the
tire.
• Do not use the tire sealant if the tire has
been damaged by being driven when insuf
ficiently inflated (e.g. bumps, cuts, cracks
etc. on the tire).
• Allow escaped tire sealant to dry, then peel
it off.• Immediately wash all painted surfaces that
came into contact with the tire sealant using
a damp cloth.
• Avoid skin and eye contact with the tire
sealant.
• Do not swallow the tire sealant.
• Allow the tire sealant that is inside the
damaged tire to dry and dispose of together
with the tire.
• Do not use the tire sealant after the expira
tion date has elapsed (see top of container).
Instead, have it replaced at an authorized
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
circumstances.
If you are unsure of the condition of the
tire or have any question whatsover
about its suitability for driving contact
the nearest smart center for assistance
or call Roadside Assistance.

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!
Keep the tire sealant out of reach of
children. If swallowed, rinse mouth imme
diately with plenty of water and drink
plenty of water.
Do not induce vomiting!
Consult a physician immediately.
Keep away from open flame, heat source
or sparks. Do not smoke.
G
Warning!
Follow safety instructions on the electric
air pump label.

The vehicle's battery is drained by use of
the electric air pump. You should therefore
keep the engine running in the open air
while inflating the tire.
>PressI on electric air pump switch
7.
The electric air pump is switched on and
inflates the tire.
i
First, the sealant is pumped into the tire.
The pressure may briefly increase to a high
value. This is normal and not an indication of a
malfunction. Do not switch off the electric air
pump.>Let the electric air pump inflate the tire for
a maximum of ten minutes.
Pressure gauge
2 must display at least
26 psi (1.8 bar) is reached. The filler hose
can become hot during inflation.
Please exercise appropriate caution.
!
Do not operate the electric air pump
longer than ten minutes without interruption.
Otherwise it may overheat.
You may operate the electrical air pump again
after it has cooled off.
>If the tire inflation pressure of at least
26 psi (1.8 bar) is not attained, turn off the
electric air pump by pressing0 on electric
air pump switch
7.
>Unscrew the end of filler hose
4
from the
tire valve.
>After clearing the area around the vehicle
of people and obstacles, drive vehicle back
or forth very slowly approximately 30 ft
(10 m).
This serves to better distribute the tire
sealant material inside the tire.>Screw the end of filler hose
4 onto the tire
valve.
>Inflate the tire again.
>After attaining a tire inflation pressure of
26 psi (1.8 bar), press0 on electric air
pump switch
7.
The electric air pump is switched off.
>Turn the key in the starter switch to
position0.
G
Warning!
If a tire inflation pressure of 26 psi
(1.8 bar) is not attained, the tire is too
severely damaged for the tire sealant to
provide a reliable tire repair.
In this case, the tire sealant cannot
properly seal the tire.
Do not drive the vehicle.
Contact the nearest smart center for as
sistance or call Roadside Assistance.

G
Warning!
Do not exceed vehicle speed of
50 mph (80 km/h). A tire sealant repair is
not designed to operate at higher
speeds.
The sticker must be attached on the
instrument cluster where it will be easily
seen by the driver.
Vehicle handling characteristics of a tire
sealant repaired tire may change. Adapt
your driving accordingly.
G
Warning!
If tire inflation pressure has fallen below
20 psi (1.3 bar) 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.

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.>Drive to the nearest authorized smart cen
ter, to have the damaged tire replaced.
>Contact an authorized smart center as soon
as possible to obtain a new filler hose
4 and
a new tire sealant container
9.
>Bring used tire sealant materials to an
authorized smart center for proper dispos
al.
>Replace your tire sealant container every
4 years. Replacement containers are avail
able at any authorized smart center.
G
Warning!
Follow recommended tire inflation
pressures.
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 underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel econ
omy, and are more likely to fail from being
overheated.
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 Bpillar. Overload
ing the tires can overheat them, possibly
causing a blowout. Overloading the tires
can also result in handling or steering
problems, or brake failure.
G
Warning!
After changing a tire, contact a smart
center to make sure that the bolts holding
the wheel to the car are tight enough.
Otherwise, the wheels could come off.
Each bolt should be tightened to a torque
of 81 lbft (110 Nm).

>> Technical data.
!
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 ABS
or 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
• poor handling characteristics
• increased noise
• 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
Bpillar (
page 185).
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.
