Distronic* is deactivated because the
functionality is impaired by external in-
terferences, e.g. high-frequency sources
such as too stations, speed measuring
systems etc.
Leave the area of the external interference.
Activate Distronic* again (
page 223) when
the message

Detach the electric air pump.
Stow electrical plug3 and air hose4
behind flap1 and place the air pump
back in the trunk.Lowering the vehicle
Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.
Remove the jack.
1-5 Wheel bolts
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of 96 lb-ft
(130 Nm).
Before storing the jack in the trunk, it
should be fully collapsed.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout)
because they are more likely to become
punctured 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.i
Vehicles with Advanced TPMS*:
Do not activate the tire inflation pressure moni-
tor (page 309) until a full size wheel/tire with
functioning sensor has been placed back into
service on the vehicle.
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 lb-ft (130 Nm).i
Wrap the damaged wheel in the protective
film that comes with the spare wheel and put the
wheel in the trunk.
You can also place the damaged wheel down into
the spare wheel well. In this case, you must stow
the luggage bowl in the trunk.
