WARNING
If you feel a sudden significant vibration
or ride disturbance, or you suspect that
possible damage to your vehicle has occur- red, you should turn on the hazard warning
flashers, carefully slow down, and drive
with caution to an area which is a safe dis-
tance from the road.
Inspect the tires and the vehicle underbody for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to the nearest smart center or tire dealer for
repairs.
Treadwear indicators (TWI) are required by law. These indicators are located in six
places on the tread circumference and
become visible at a tread depth of approx-
imately 1
/ 16 in (1.6 mm), at which point the
tire is considered worn and should be
replaced.
The treadwear indicator appears as a solid
band across the tread. G
WARNING
Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately 1
/ 16 in
(1.6 mm), we recommend that you do not allow your tires to wear down to that level. As
tread depth approaches 1
/ 8 in (3 mm), the
adhesion properties on a wet road are
sharply reduced. Depending upon the weather and/or road
surface (conditions), the tire traction var- ies widely.
Specified tire inflation pressures must be maintained. This applies particularly if
the tires are subject to high loads (e.g.
high speeds, heavy loads, high ambient
temperatures). G
WARNING
Do not drive with a flat tire. A flat tire will affect your ability to steer or brake and maycause you to lose control of the vehicle.
Continued driving with a flat tire or driv-
ing at high speed with a flat tire will cause
excessive heat build-up and possibly a
fire.
For more information, see “Tires and
wheels” (Y page 127). Hydroplaning
Depending on the depth of the water layer
on the road, hydroplaning may occur
resulting in a loss of control, even at low
speeds and with new tires. Reduce vehicle
speed, avoid track grooves in the road and
apply brakes cautiously when it is raining. Tire traction
The safe speed on a wet, snow covered or icy
road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside temperatures are close to the freezing
point. G
WARNING
If ice has formed on the road, tire traction will be substantially reduced. Under such
weather conditions, drive, steer and brake
with extreme caution.

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. 164
Display messages>> Practical hints.

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 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. Display messages Possible causes/consequences and

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 lowtire pressure telltale. When the system detects a malfunction, the telltale will flash for

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.

by use of the electric air pump. You
should therefore keep the drive system
running while inflating the tire. X
Press Ion electric air pump switch C.
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.
X Let the electric air pump inflate the tire
for a maximum of ten minutes.
Pressure gauge ;must display at least
180 kPa (1.8 bar, 26 psi). !
Do not operate the electric air pump
longer than ten minutes without inter-
ruption. Otherwise it may overheat.
You may operate the electrical air pump
again after it has cooled off.
X If a tire inflation pressure of at least
180 kPa (1.8 bar, 26 psi) is not attained,
turn off the electric air pump by press-
ing 0on electric air pump switch C.
X Unscrew the end of filler hose ?from
tire valve G.
X After clearing the area around the vehi-
cle of people and obstacles, drive vehi-
cle back or forth very slowly approx-
imately 30 ft (10 m).
This serves to better distribute the tire sealant material inside the tire.
X Screw the end of filler hose ?onto tire
valve G.
X Inflate the tire again. G
WARNING
If a tire inflation pressure of
180 kPa (1.8 bar, 26 psi) is not attained, the tire is too severely damaged for the tire
sealant to provide a reliable tire repair.

! The manufacturer is unable to guaran-
tee that all tire punctures can be
repaired with the tire repair kit, in par-
ticular 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. G
WARNING
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and energy con-
sumption of the vehicle, 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. Flat tire
