Practical hints
Flat tire
̈ Inflate the spare wheel tire to the
recommended tire inflation pressure
given in the “Technical data” section
(
page 529).
This takes about 5 minutes for the
collapsible tire.
̈ Press 0 on electric air pump switch 2.
̈ Turn the SmartKey in the starter switch
to position 0.
̈ Vehicles with KEYLESS-GO*:
Press the KEYLESS-GO start/stop
button twice without depressing
the brake pedal.
̈ If the tire inflation pressure is above
the recommended tire inflation pres-
sure given in this Operator’s Manual,
release excess tire inflation pressure
using the vent screw.
̈ Detach the electric air pump.
̈ Store the electrical plug and the air
hose behind the flap and place the
electric air pump back in the vehicle
tool kit storage well.
Warning! G
Air hose 4 and union nut 5 can become
hot during inflation. Exercise proper caution
to avoid burning yourself when using the
equipment.
!
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
after it has cooled off.
!
Please compare the recommended tire in-
flation pressure for your vehicle with the tire in-
flation 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 tire to
the recommended tire inflation pressure given
on the yellow label on the spare wheel rim.
Warning! G
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.
