In the case of a flat tire, you may tempo-
rarily use the Minispare wheel when ob-
serving the following restrictions:

Do not exceed a vehicle speed of
50 mph (80 km / h).


Drive to the nearest tire repair facility
to have the flat tire repaired or re-
placed as appropriate.

Open flap 1 on the air pump.

Pull out electrical plug 3 and air hose
with pressure gauge 4.

Make sure the vent screw on air hose is
closed.

Remove the valve cap from the tire
valve.
Warning!
G
The dimensions of the Minispare wheel and
the collapsible tire are different from those
of the road wheels. As a result, the vehicle
handling characteristics change when driv-
ing with a Minispare wheel mounted.
The spare wheel should only be used tempo-
rarily, and replaced with a regular road
wheel as quickly as possible.
!Do not lower the vehicle before inflat-
ing the collapsible tire. Otherwise the
rim may be damaged.Warning!
G
Observe instructions on air pump label.


430 Practical hintsFlat tire
Screw air hose 4 onto the tire valve.

Insert electrical plug 3 into vehicle ci-
gar lighter socket.

Turn the SmartKey in the ignition to
position1.
or

Press the KEYLESS-GO* start/stop
button on the gear selector lever once
without depressing the brake pedal.

Press I on electric air pump switch 2.
The electric air pump should now
switch on and inflate the tire.

Inflate the tire to approx. 51 psi
(3.5 bar).
This takes about five minutes for the
collapsible tire. Air hose 4 and union
nut5 can become hot duration infla-
tion. Exercise proper caution to avoid
burning yourself when using the equip-
ment.

Press 0 on electric air pump switch 2.

Turn the SmartKey in the ignition to
position0.
or

Press KEYLESS-GO* start/stop button
on the gear selector lever twice without
depressing the brake pedal.
The electric air pump should now be
switched off.

If the tire inflation pressure is above
51 psi (3.5 bar), release excess tire in-
flation pressure using the vent screw.

Detach the electric air pump.

Stow electrical plug 3 and air hose 4
behind flap 1 and place the air pump
back in the trunk.
!Do not operate the air pump longer
than eight minutes without interrup-
tion. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
