MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flatcharacteristics), you can continue to drive yourvehicle even if there is a total loss of pressurein one or more tires. The affected tire must notshow any clearly visible damage.
You can recognize an MOExtended tire by theMOExtended marking which appears on thesidewall of the tire. You will find this markingnext to the tire size designation, the load-bear-ing capacity and the speed index(Ypage 320).
MOExtended tires may be used only in con-junction with an activated tire pressure losswarning system (Canada only) or tire pressuremonitor (USA only).
If a pressure loss warning messageappears in the multifunction display:
Robserve the instructions in the display mes-sages (Ypage 223).
Rcheck the tire for damage
Rif driving on, observe the following notes
The driving distance possible in run-flat modeis approximately 50 miles (80 km) when thevehicle is partially laden. When the vehicle isfully laden it is approximately 19 miles(30 km).
In addition to the vehicle load, the driving dis-tance possible depends upon:
RVehicle speed
RRoad condition
ROutside temperature
The driving distance possible in run-flat modemay be reduced by extreme driving conditionsor maneuvers, or it can be increased through amoderate style of driving.
The driving distance possible in run-flat modeis counted from the moment the tire pressureloss warning appears in the multifunction dis-play.
You must not exceed the maximum permissi-ble speed for limp-home mode of 50 mph(80 km/h).
When replacing one or all tires, please observethe following specifications for your vehicle'stires:
RSize
RType and
RThe "MOExtended" marking
If a tire has gone flat and cannot be replacedwith an MOExtended tire, a standard tire maybe used as a temporary measure. Make surethat you use the proper size and type (summeror winter tire).
Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory.It is therefore recommended that you addition-ally equip your vehicle with a TIREFIT kit if youmount tires that do not feature run-flat charac-teristics, e.g. winter tires. A TIREFIT kit may beobtained from a qualified specialist workshop.

Towing and tow-starting
Important safety notes
GWARNING
Functions relevant to safety are restricted or
no longer available if:
Rthe engine is not running
Rthe brake system or the power steering is
malfunctioning
Rthere is a malfunction in the power supply
or the vehicle's electrical system
When your vehicle is towed away or towed
started, you may require considerably more
effort to steer and brake. There is a risk of
an accident.
In such cases, use a tow bar. Before being
towed away or tow started, make sure the
steering moves freely.
GWARNING
You can no longer steer the vehicle if the
steering wheel lock has been engaged.
There is a risk of an accident.
Always switch off the ignition when towing
the vehicle with a tow cable or a tow bar.
GWARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissi-
ble gross weight of your vehicle, the:
Rthe towing eye could detach itself
Rthe vehicle/trailer combination could roll-
over.
There is a risk of an accident.
When towing or tow-starting another vehi-
cle, its weight should not be greater than
the permissible gross weight of your vehicle.
Details on the permissible gross vehicle weightof your vehicle can be found on the vehicleidentification plate (Ypage 333).
!When Active Brake Assist, Active DistanceAssist DISTRONIC or the HOLD function isactivated, the vehicle brakes automaticallyin certain situations.
To avoid damage to the vehicle, deactivatethese systems in the following or similar sit-uations:
Rwhen towing the vehicle
Rin the car wash
!Make sure that the electric parking brakeis released. If the electric parking brake isfaulty, visit a qualified specialist workshop.
!Only secure the tow rope or tow bar at thetowing eyes. Otherwise, the vehicle could bedamaged.
!Do not use the towing eyes for recoverypurposes as this could damage the vehicle.If in doubt, recover the vehicle with a crane.
!When towing, pull away slowly andsmoothly. If the tractive power is too high,the vehicles could be damaged.
!The vehicle can be towed a maximum of30 miles (50km). The towing speed of30 mph (50km/h) must not be exceeded.
If the vehicle has to be towed more than30 miles (50km), the front axle must beraised or the entire vehicle raised and trans-ported.
!Do not tow with sling-type equipment. Thiscould damage the vehicle.
!When towing away vehicles with KEYLESS-GO, use the key instead of the Start/Stopbutton. The automatic transmission mayotherwise shift to position]when youopen the driver's or front-passenger door,which could damage the transmission.
!Vehicles with automatic transmission mustnot be started by tow-starting. This couldotherwise damage the transmission.
It is better to have the vehicle transportedthan to have it towed away.
If the vehicle can no longer be driven becauseof an accident or breakdown, you have the fol-lowing options:
RTransporting the vehicle.
As a rule, you should have the vehicle trans-ported.
RTowing the vehicle with a tow rope or towbar.
Only tow the vehicle in exceptional cases.

Roadside Assistance

The battery must be connected and charged.Otherwise, you:
Rcannot turn the SmartKey to positionHinthe ignition lock.
Rcannot release the electric parking brake.
Rcannot shift the transmission to position\\.
The function of the electric parking brake andthe parking lock is dependent on the on-boardvoltage.
If the on-board voltage is low or if there is asystem malfunction:
Rthe electric parking brake may not beapplied in certain circumstances, or
Rit may no longer be possible to shift thetransmission to position]
Switch off non-essential consumers, e.g. theradio.
Deactivate the automatic locking featurebefore the vehicle is towed (Ypage 199). Youcould otherwise be locked out when pushingor towing the vehicle.
Installing/removing the towing eye
Installing the towing eye
The brackets for the screw-in towing eye arelocated in the bumpers. They are at the rearand at the front, under coversC.
XRemove the towing eye from the stowagespace.
The towing eye is located with the vehicletool kit under the cargo compartment floor(Ypage 287).
Vehicles with the TIREFIT kit: the towing eyeis beneath the tire inflation compressor(Ypage 287).
XPress the mark on coverCinwards in thedirection of the arrow.
XTake coverCoff the opening.
XScrew in the towing eye clockwise to thestop.
Removing the towing eye
XUnscrew and remove the towing eye.
XAttach coverCto the bumper and pressuntil it engages.
XPlace the towing eye in the stowage wellbeneath the cargo compartment floor in thecargo compartment (Ypage 287).
XVehicles with the TIREFIT kit: put back thetire inflation compressor (Ypage 287).
Towing the vehicle with the front
axle raised
Observe the important safety notes when tow-ing your vehicle with the front axle raised(Ypage 298).
Only vehicles without 4MATIC can betowed with the front axle raised.
!Vehicles with 4MATIC must not be towedwith either the front or the rear axle raised,as doing so will damage the transmission.
Vehicles with 4MATIC may either be towedaway with both axles on the ground or be loa-ded up and transported.
!The ignition must be switched off if thevehicle is being towed with the front axle
raised. Otherwise, ESP®may intervene anddamage the brake system.
XOn vehicles with KEYLESS-GO or theKEYLESS-GO start function:you must usethe SmartKey instead of the Start/Stop but-ton (Ypage 126).
XMake sure that the vehicle is stationary.
XTurn the SmartKey to positionHin the igni-tion lock.
