Flat tire
̈ Open flap 1 on electric air pump.
̈ Pull out electrical plug 3 and air hose
with pressure gauge 4.
̈ Remove the valve cap from valve.
̈ Screw air hose 4 onto the tire valve.
̈ Insert electrical plug 3 into vehicle
cigarette lighter socket.
̈ Turn the SmartKey in the starter switch
to position 1.
̈ Press I on electric air pump switch 2.
The electric air pump should now
switch on and inflate the spare tire.
̈ Inflate the spare tire to approximately
36 psi (2.5 bar).
This takes about five minutes for the
spare tire. Air hose 4 and union
nut 5 can become hot during 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 starter switch
to position 0.
̈ If the tire pressure is above 36 psi
(2.5 bar), release excess tire pressure
using the vent screw.
̈ Detach the electric air pump.
̈ Store the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.
!
Do not operate the electric air pump
longer than six minutes without
interruption. Otherwise it may over-
heat.
You may operate the electric air pump
again after it has cooled off.
Warning! G
Follow recommended inflation pressures.
Do not overinflate tires. Overinflated 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.
