Lowering the vehicle
G
WARNING
Tire pressure that is too high or too low can
lead to a blowout of the mounted emergency
spare wheel/spare wheel, particularly when
driving with a heavy load and increasing
speed .There is a risk of accident.
Check the tire pressure of the emergency
spare wheel or spare wheel and adjust it.
When doing so, observe the specified tire
pressure.
! Inflate the collapsible spare wheel using
the tire inflation compressor before
lowering the vehicle. The wheel rim could
otherwise be damaged.
X Turn the crank of the jack counter-
clockwise until the vehicle is once again
standing firmly on the ground.
X Place the jack to one side. G
WARNING
The wheels could work loose if the wheel nuts
and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
X Tighten the wheel bolts evenly in a
crosswise pattern in the sequence
indicated ( 0002to0020). The tightening torque
must be 96 lb-ft (130 Nm).
X Turn the jack back to its initial position and
store it together with the rest of the tire- change tool kit in the stowage well under
the trunk floor.
X Vehicles with AMG equipment: insert the
cover into the outer sill.
X Place the damaged wheel in the protective
covering (if available) from the tire-change
tool kit, and stow it in the trunk.
The roof must be closed when doing so.
i USA only: when you are driving with the
emergency spare wheel mounted, the tire
pressure monitoring system cannot
function reliably. Only restart the tire
pressure monitoring system when the
defective wheel has been replaced with a
new wheel.
All wheels mounted must be equipped with
functioning sensors. The defective wheel
should no longer be in the vehicle. MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires.
MOExtended tires may only be used in
conjunction with the activated tire pressure
loss warning system or with the activated tire
pressure monitoring system.
The driving distance in partially laden
condition is approximately 50 miles (80 km),
and approximately 18 miles (30 km) when
fully loaded.
In addition to the vehicle load, the driving
distance possible depends upon:
R speed
R road condition
R outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving
conditions/maneuvers, or it can be increased
through a moderate style of driving. Flat tire
