1 Flap
2 On/off switch

4 Air hose with pressure gauge and vent
screw
5 Union nut
Open flap 1 on electric air pump.
Pull out electrical plug 3 and air hose
with pressure gauge 4.
Remove the valve cap from the
collapsible tire valve.
Screw union nut 5 onto the collaps-
ible 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 collapsible
tire.
Inflate the tire to approximately 51 psi
(3.5 bar).
This takes about 5 minutes for the col-
lapsible 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 8 minutes without interruption. Otherwise it
may overheat.
You may operate the electric air pump again af-
ter it has cooled off.
Press 0 on electric air pump switch 2.
Practical hints
Turn the SmartKey in the starter switch
to position 0.
If the tire pressure is above 51 psi
(3.5 bar), release excess tire pressure
using the vent screw.
Warning!
Follow recommend tire 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.
Detach the electric air pump.
