nut 3 can become hot duration infla-
tion. Exercise proper caution to avoid
burning yourself when using the equip-
ment.

317 Practical hints
Flat tire

Press 0 on the electric air pump switch.

Turn the key in the ignition to
position0.
or

Press KEYLESS-GO* start/stop button
on the selector lever twice without de-
pressing the brake pedal.
The electric air pump should now be
switched off.

If the tire pressure is above 36 psi
(2.5 bar), release excess tire pressure
using the vent screw.

Detach the electric air pump.

Stow the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.
!Do not operate the air pump longer
than eight minutes without interrup-
tion. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
Warning!
G
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.
iThe flat tire may be transported in the
trunk when the retractable hardtop is
lowered. Use the protective sheet pro-
vided with the spare wheel. Do not ac-
tivate the tire inflation pressure
monitor until the deflated tire has been
removed from the vehicle.
