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.
MOExtended system*
The MOExtended system allows you to
continue driving your vehicle even if there
is a total loss of pressure in one or more
tires.
You may only use the MOExtended system
in conjunction with the Run Flat Indicator*
or the Advanced TPMS* (Canada only)
(page 314).
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 protec-
tive 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.
!The maximum distance in emergency
mode depends on the vehicle’s load. It
is 30 miles (50 km) if the vehicle is par-
tially loaded and 18 miles (30 km) if the
vehicle is fully loaded.
The point at which the maximum driv-
ing distance begins in emergency
mode is when the warning message
appears in the multifunction display
indicating that there is a loss of tire
inflation pressure.
Do not exceed the maximum speed of
50 mph (80 km/h).

method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
!The battery, its filler caps and the
battery ventilation tube must always be
securely installed when the vehicle is in
operation.
!Never invert the terminal connections!
iThe following procedures must be car-
ried out following any interruption of
battery power (e.g. due to reconnec-
tion):
Set the clock (
page 162)
(see COMAND operator’s manual).
Resynchronize the ESP
®
(
page 368).
Resynchronize the side windows
