do so.
Warning!G
The dimensions of the spare wheel
(Minispare or collapsible tire) are different
from those of the road wheels. As a result,
the vehicle handling characteristics change
when driving with a spare wheel mounted.
Adapt your driving style accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP

Incorrect wheel bolts or improperly tight-
ened wheel bolts can cause the wheel to
come off. This could cause an accident. Be
sure to use the correct wheel bolts.

418 Practical hints
Flat tire
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.
iVehicles 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).
iWrap 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.

on the spare wheel rim differs from the values
given in this Operator’s Manual, inflate the spare
wheel tire to the recommended tire inflation
pressure given on the yellow label on the spare
wheel rim.iPlease note that the tire inflation pressure of
the Minispare tire and the collapsible tire differs
from the tire inflation pressure of the road tires.
