XMake sure pressure release screw F on
pressure gauge G is fully closed.XScrew filler hose D onto valve E.XInsert connector A into the socket in the
footwell of the second row of seats
( Y page 268).
!
None of the other sockets or cigarette
lighters are designed for operating the tire
inflation compressor.
XTurn the SmartKey to position
1 (Y page 145) in the ignition lock.XPress on/off switch ? on the tire inflation
compressor to I.
The tire inflation compressor is switched
on. The tire is inflated.
i First, TIREFIT is pumped into the tire. The
pressure can briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tire inflation
compressor during this phase.
XAllow the tire inflation compressor to run
for five minutes. The tire should then have
attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
! Do not operate the tire inflation
compressor for longer than eight minutes
at a time without a break. It may otherwise
overheat.
The tire inflation compressor can be
operated again once it has cooled down.
If a pressure of 180 kPa (1.8 bar/26 psi) has
been achieved after five minutes, see
( Y page 302).
If a pressure of 180 kPa (1.8 bar/26 psi) has
not been achieved after five minutes, see
( Y page 302).

XInflate the tire to the specified tire
pressure.
The specified tire pressure is printed on the
yellow label of the emergency spare wheel.XWhen the specified tire pressure has been
reached, press on/off switch 2 on the
electric air pump to 0.
The tire inflation compressor is switched
off.XTurn the SmartKey to position 0 in the

the specified pressure, open the pressure
release screw on pressure gauge 4 until
the correct tire pressure has been reached.XVersion 2: if the tire pressure is higher than
the specified pressure, press pressure
release button 6 until the correct tire
pressure has been reached.XUnscrew union nut A on the air hose from
the valve.XScrew the valve cap onto the collapsible
spare wheel valve again.XVersion 1 : stow plug = and the air hose
