MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat char-acteristics), you can continue to drive your vehi-cle even if there is a total loss of pressure in oneor more tires. The affected tire must not showany clearly visible damage.
You can recognize a 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 305).
MOExtended tires may be used only in conjunc-tion with an activated tire pressure loss warningsystem (Canada only) or tire pressure monitor(USA only).
If a pressure loss warning message appearsin the multifunction display:
Robserve the instructions in the display mes-sages (Ypage 213).
Rcheck the tire for damage
Rif driving on, observe the following notes
The driving distance possible in run-flat mode isapproximately 50 miles (80 km) when the vehi-cle is partially laden. When the vehicle is fullyladen 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 mode iscounted from the moment the tire pressure losswarning appears in the multifunction display.
You must not exceed a maximum speed of50 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 a MOExtended tire, a standard tire may beused as a temporary measure. Make sure thatyou use the proper size and type (summer orwinter tire).
Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory. Itis therefore recommended that you additionallyequip your vehicle with a TIREFIT kit if you mounttires that do not feature run-flat properties, e.g.winter tires. A TIREFIT kit may be obtained froma qualified specialist workshop.
Important safety notes
GWARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is a risk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, potholes,
off-road). This applies in particular to a laden
vehicle.
Stop driving in emergency mode if:
Ryou hear banging noises.
Rthe vehicle starts to shake.
Ryou see smoke and smell rubber.
RESP®is intervening constantly.
Rthere are tears in the sidewalls of the tire.
After driving in emergency mode, have the

Battery (vehicle)
Important safety notes
Special tools and expert knowledge are requiredwhen working on the battery, e.g. removal andinstallation. You should therefore have all workinvolving the battery carried out at a qualifiedspecialist workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevant systems, e.g. the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP®(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
Rwhen braking
Rin the event of abrupt steering maneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci-
dent, contact a qualified specialist workshop
immediately. Do not drive any further. You
should have all work involving the battery car-
ried out at a qualified specialist workshop.
For further information about ABS and ESP®,see (Ypage 61) and (Ypage 64).
GWARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms whencharging the battery as well as when jump-start-ing.
Always make sure that neither you nor the bat-tery is electrostatically charged. A build-up ofelectrostatic charge can be caused, for exam-ple:
Rby wearing clothing made from syntheticfibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across the car-pet or other synthetic materials
Rif you rub the battery with a cloth
GWARNING
During the charging process, a battery produ-
ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
RMake sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
RNever place metal objects or tools on a bat-
tery.
RIt is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
RWhen jump-starting, make sure that the
battery poles with identical polarity are
connected.
RIt is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with

MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat char-acteristics), you can continue to drive your vehi-cle even if there is a total loss of pressure in oneor more tires.
MOExtended tires may only be used in conjunc-tion with an activated tire pressure loss warningsystem (Canada only) or tire pressure monitor(USA only) and only on wheels specifically tes-ted by Mercedes-Benz.
Notes on driving with MOExtended tires with aflat tire (Ypage 275).
Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory. Itis therefore recommended that you additionallyequip your vehicle with a TIREFIT kit if you mounttires that do not feature run-flat properties, e.g.winter tires. A TIREFIT kit may be obtained froma qualified specialist workshop.
Winter operation
General notes
Have your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"section (Ypage 310).
Driving with summer tires
At temperatures below 45 ‡(+7 †), summertires lose elasticity and therefore traction andbraking power. Change the tires on your vehicleto M+S tires. Using summer tires at very coldtemperatures could cause cracks to form,thereby damaging the tires permanently.Mercedes-Benz cannot accept responsibility forthis type of damage.
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.

Snow chains
GWARNING
If snow chains are mounted on the rear
wheels, the snow chains could cause abrasion
to the vehicle body or to chassis components.
This could cause damage to the vehicle or the
tires. There is a risk of an accident.
To avoid hazardous situations:
Rnever mount snow chains on the rear
wheels
Ronly mount snow chains in pairs on the
front wheels.
!On some tire sizes there is not enough spacefor snow chains. To avoid damage to the vehi-cle or tires, observe the "Wheel and tire com-binations" section under "Tires and wheels".
For safety reasons, Mercedes-Benz recom-mends that you only use snow chains that havebeen specially approved for your vehicle byMercedes-Benz, or are of a correspondingstandard of quality. For more information,please contact a qualified specialist workshop.
If you intend to mount snow chains, please bearthe following points in mind:
RSnow chains may not be mounted on allwheel/tire combinations. Permissible wheel-tire combinations (Ypage 315).
ROnly use snow chains when driving on roadscompletely covered by snow. Remove thesnow chains as soon as possible when youcome to a road that is not snow-covered.
RLocal regulations may restrict the use of snowchains. Observe the appropriate regulations ifyou wish to mount snow chains.
RDo not exceed the maximum permissiblespeed of 30mph (50 km/h).
RIf snow chains are installed, you cannot useActive Parking Assist (Ypage 167).
You may wish to deactivate ESP®when pullingaway with snow chains installed . This allows thewheels to spin in a controlled manner, achievingincreased propulsive force (cutting action).
