Practical hints
Flat tire
Press I on electric air pump switch 2.
The electric air pump switches on and
inflates the collapsible tire.
Inflate the collapsible tire to approxi-
mately 51 psi (3.5 bar).
This takes about five minutes for the
collapsible 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.
!
Do not operate the electric air pump
longer than six minutes without inter-
ruption. Otherwise it may overheat.
You may operate the electric air pump
again after it has cooled off.

Press 0 on electric air pump switch 2.
Turn the SmartKey in the starter switch
to position 0.
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
on air hose 4.
Warning!
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being over-
heated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.
Detach the electric air pump.
Reinstall collapsible tire valve cap.
Store electrical plug 3 and air
hose 4 behind flap 1 and place the
electric air pump back in the trunk.
