iVehicles retrofitted with TIREFIT kit:
Only use the power outlet in the second-
row footwell for electric air pump
operation.
You can use the power outlet even when
the ignition is switched off, e.g. in order to
inflate the collapsible tire.
An emergency shut-off feature is designed
to prevent the vehicle’s on-board voltage
from dropping below a minimum level. If
the on-board voltage drops to this
minimum level, the power outlets are
switched off automatically to help preserve
engine starting power.
Sealing tires with TIREFIT
This section applies to vehicles retrofitted
with a TIREFIT kit only.
Small tire punctures, particularly those in the
tread, can be sealed with TIREFIT.
TIREFIT can be used in ambient temperatures
down to -4‡ (-20†).
GWarning!
TIREFIT is a limited repair device. TIREFIT
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.
Contact the nearest authorized Mercedes-
Benz Center for assistance or call Roadside
Assistance.
XForeign objects (e.g. screws or nails)
should not be removed from the tire.
XTake the TIREFIT kit, the sticker, and the
electric air pump out of the vehicle.
Two-part sticker
XAttach upper part : of the sticker where
it will be easily seen by the driver on the
instrument cluster.
XAttach lower part ; of the sticker to the
damaged tire (close to the tire valve).
GWarning!
Take care not to allow the contents of TIREFIT
to come in contact with hair, eyes or clothing.
TIREFIT is harmful if inhaled, swallowed or
absorbed through the skin - causes skin, eye
and respiratory irritation.
Any contact with eyes or skin should be
flushed immediately with plenty of water.
If clothing comes in contact with TIREFIT,
change clothing as soon as possible.
In case of allergic reaction or rash, consult a
physician immediately.
GWarning!
Keep TIREFIT out of reach of children. If
swallowed, rinse mouth immediately with
plenty of water and drink plenty of water.
Do not induce vomiting!
Consult a physician immediately.
