Preparing the vehicle
Your vehicle may be equipped with:
R MOExtended tires (tires with run-flat
properties) (Y page 321)
Vehicle preparation is not necessary on
vehicles with MOExtended tires.
R an emergency spare wheel(Y page 367)
Information on changing/mounting awheel
(Y page 357).
X Stop the vehicle on solid, non-slippery and
level ground, as far away as possible from
traffic.
X Switch on the hazard warning lamps.
X Secure the vehicle against rolling away
(Y page 167).
X If possible, bring the front wheels into the
straight-ahead position.
X Vehicles with AIRMATIC: make sure that
"normal" level is selected (Y page 189).
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove
the SmartKey from the ignition lock.
X Vehicles with KEYLESS-GO: open the
driver's door.

All occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
X Make sure that no one is near the danger
area while awheel is being changed.
Anyone who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Get out of the vehicle. Pay attention to
traffic conditionsw hen doing so.
X Close the driver's door. MOExtended tires (tires with run-flat
properties)
General notes With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is
atotal loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognizeM OExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-
bearing capacity and the speed index
(Y page 351).
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If the pressurel oss warning message
appearsint he multifunction display:
R Observe the instructions in the display
messages (Y page 258).
R Check the tire for damage.
R If driving on, observe the following notes.
The maximum driving distance is
approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
18 miles (30 km) when the vehicle is fully
laden. Flat tire

bod ytor emove any existing electrostatic
build-up.
The highly flammable ga smixture forms when
charging the battery as well as whe njump-
starting.
Always mak esure that neither you no rthe
battery is electrostatically charged. Abuild-
up of electrostati ccharge can be caused, for
example:
R by wearing clothing made from synthetic
fibers
R due to friction between clothing and seats
R if you push or pull the battery across the
carpet or other synthetic materials
R if you wipe the battery with acloth G
WARNING
During the charging process, abattery
produces hydrogen gas. If ashort circuit
occurs or sparks are created, the hydrogen
gas can ignite. There is arisk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
R Never place metal objectsort ools on a
battery.
R It is important that you observe the
described order of the battery terminals
when connecting and disconnecting a
battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and
disconnecting the jumper cables.
R Never connect or disconnectt he battery
terminals while the engine is running. G
WARNING
Batterya cid is caustic. There is arisk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention.

Environmental note Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment. Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to aqualified
specialist workshop or a
special collection point for
used batteries.
! Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the
MaintenanceB ooklet or contact aqualified
specialist workshop for more information.
! You should have all work involving the
battery carried out at aqualified specialist
workshop. In th eexcepti onal cas ethatitis
necessar yfor you to disconnect th ebattery
yourself, mak esure that:
R you switch off th eenginea nd remove the
SmartKey. On vehicles wit hKEYLESS-
GO, ensure that th eignition is switched

WARNING
If you manipulate or bridge afaulty fuse or if
you replace it with afuse with ahigher
amperage, the electric cables could be
overloaded. This could result in afire. There
is ar isk of an accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
! Only use fuses that have been approved
for Mercedes-Ben zvehicles and which
have the correct fuse ratin gfor the system
concerned. Otherwise, componentsor
systems could be damaged.
The fuses in your vehicle serve to close down
faulty circuits. If afuse blows ,all the
component sonthecircuit and their functions
stop operating.

the same rating, which you can recognize by
the color and value. The fuse ratings are listed
in the fuse allocation chart.

General notes If
at ire pressure monitor is installed, the
vehicle's wheels have sensors that monitor
the tire pressures in all four tires. The tire
pressure monitor warns you if the pressure
drops in one or more of the tires. The tire
pressure monitor only functions if the correct
sensors are installed on all wheels.
Information on tire pressures is displayed in
the multifunction display. After afew minutes
of driving, the current tire pressure of each
tire is shown in the Service menu of the
multifunction display. For further information
on displaying this message, refer to the
"Checking the tire pressure electronically"
section (Y page 344). 342
CheckWheels and tires

The tire pressure monitor has
ayellow
warning lamp in the instrument cluster for
indicatin gapressure loss or malfunction.
Whether the warning lamp flashes or lights up
indicates whether atire pressure is too low or
the tire pressure monitor is malfunctioning:
R if the warning lamp is lit continuously, the
tire pressure on one or more tires is
significantly too low. The tire pressure
monitor is not malfunctioning.
R if the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
If the tire pressure monitor is malfunctioning,
it may take more than ten minutes for the tire
pressure warning lamp to inform you of the
malfunction by flashing for approximately one
minute and then remaining lit. When the
malfunction has been rectified, the tire
pressure warning lamp goes out after afew
minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those
measured at agas station with apressure
gauge. The tire pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tire pressure
values indicated by apressure gauge are
higher than those shown by the on-board
computer .Inthis case, do not reduce the tire
pressures.
The operation of the tire pressure monitor can
be affected by interference from radio
transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.

After ateach-in process, the tire pressure
monitor automatically detects new wheels or

the tire pressure value to the individual

essage is shown
instead of the tire pressure display. The tire
