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 interrup-
tion. 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.
If the tire pressure is above 51 psi
(3.5 bar), release excess tire pressure
using the vent screw.
Warning!
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.
Detach the electric air pump.
