X
Vehicles with KEYLESS-GO: Remove the
KEYLESS-GO start/stop button from the
starter switch.
X
Have any passenger exit the vehicle at a
safe distance from the roadway. Open
doors only when conditions are safe to do
so.
i Vehicles with spare wheel with collapsible
tire or TIREFIT only:
You can use the power outlet in the second-
row footwell to operate the electric air
pump 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
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.
