XTighten the wheel bolts evenly in a
crosswise pattern in the sequence
indicated ( : to A). The tightening torque
must be 110 lb-ft (150 Nm) .GWarning!
Have the tightening torque checked
immediately after a wheel is changed. The
wheels could come loose if they are not
tightened to a torque of 110 lb-ft (150 Nm).
XTurn the jack back to its initial position and
store it together with the rest of the vehicle
tool kit in the cargo compartment.
Vehicles with an emergency spare wheel:
XWrap the faulty wheel in the protective film
included with the emergency spare wheel
and transport the wheel in the cargo
compartment.
or
XDepending on the size of the wheel, you
may also be able to secure the faulty wheel
in the emergency spare wheel well. In this
case, you must remove the stowage tray
from the emergency spare wheel well and
store it securely in the cargo compartment.
Further information on stowing the
collapsible spare wheel ( Y page 299).
i When you are driving with the collapsible
spare wheel mounted, the tire pressure
loss warning system or the tire pressure
monitor cannot function reliably. Only
restart the tire pressure loss warning
system/tire pressure monitor when the
defective wheel has been replaced with a
new wheel.
Vehicles with tire pressure monitor: all
mounted wheels must be equipped with
functioning sensors and the defective
wheel should no longer be in the vehicle.
MOExtended run-flat system
The MOExtended run-flat system allows you
to drive on even if there is a complete loss of
pressure in one or more tires.
The MOExtended run-flat system may only be
used in conjunction with the activated tire
pressure loss warning system or with the
activated tire pressure monitor.
The maximum permissible distance which
can be driven in run-flat mode depends on the
cargo in the vehicle. You can drive 50 miles
(80 km) if the vehicle is partially laden and
18 miles (30 km) if it is fully laden.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tire pressure loss warning
appears in the multifunction display.
You must not exceed a maximum speed of
50 mph(80 km/h).GWarning!
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. curbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to a large
extent on the loads placed on the vehicle. It
can be shorter due to high speeds, a heavy
cargo, sudden changes in direction, the road
surface condition, outside temperature, etc.,
or further if you drive carefully and
conservatively.
Do not continue to drive in run-flat mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
