Practical hints
Flat tire

Open flap
1 on air pump.

Pull out electrical plug 4 and air hose
with the pressure gauge 2.
Observe instructions on air pump label.

Remove the valve cap from valve.

Screw the air hose 2 on to the tire
valve.

Insert electrical plug 4 into vehicle
cigarette lighter socket.

To switch on the air pump turn the
SmartKey in the starter switch to
position 1 (
page 31).

Operate air pump until the pressure
gauge displays 36 psi (2.5 bar)
This takes about five minutes for the
space tire. The air hose 2 and the
union nut 3 can become hot during in-
flation.

To switch off the air pump turn the
SmartKey in the starter switch to
position 0 (
page 31).

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 eight minutes without in-
terruption. Otherwise it may overheat.
You may operate the air pump again af-
ter 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. Underinfalted tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the driver’s door latch
post). Overloading the tires can overheat
them, possibly causing a blowout.
