i Vehicles 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†). G
Warning!
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.
X Foreign objects (e.g. screws or nails)
should not be removed from the tire.
