̈ 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 5 minutes. Air
hose
4 and union nut 5 can become
hot during inflation. Exercise proper
caution to avoid burning yourself when
using the equipment.
̈ Press 0 on electric air pump switch 2.
̈ Turn the SmartKey in the starter switch
to position 0.
The electric air pump is switched off.
̈ If the tire inflation pressure is above
51 psi (3.5 bar), release excess tire
inflation pressure using the vent screw
on air hose
4.
̈ Detach the electric air pump.
̈ Reinstall tire valve cap.
̈ Store electrical plug 3 and air
hose 4 behind flap 1 and place the
electric air pump back in the trunk.
̈ Lower the vehicle ( ୴ page 420).
! Compare the recommended tire inflation
pressure for your vehicle with the tire inflation
pressure on the yellow label located on the spare
wheel rim.
If the tire inflation pressure on the yellow label
on the spare wheel rim differs from the values
given in this Operator’s Manual, inflate the
collapsible tire to the recommended tire inflation
pressure given on the yellow label on the spare
wheel rim.
! Do not operate the electric air pump longer
than 6 minutes without interruption. Otherwise it
may overheat.
You may operate the electric air pump again
after it has cooled off.
Warning!
G
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.
