Important safety notes
G
WARNING
Safety relevant functions are restricted or no
longer available if:
R the engine is not running
R the brake system or power steering is mal-
functioning
R there is a malfunction in the voltage 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 rigid towing bar. Before
being towed away or tow started, make sure
the steering moves freely. G
WARNING
If the steering wheel lock is engaged, the vehi- cle can no longer be steered. There is a risk of
an accident. Always switch on the ignition when towing
with a tow rope or a towing bar.

When COLLISION PREVENTION ASSIST
PLUS, DISTRONIC PLUS or the HOLD func- tion is activated, the vehicle brakes auto-
matically in certain situations. To avoid
damage to the vehicle, deactivate these
systems in the following or similar situa-
tions:
R when towing away
R in a car wash
! Make sure that the electric parking brake
is released. If the electric parking brake is
faulty, visit a qualified specialist workshop.
! Only secure the tow cable or tow bar to
the towing eyes or, if available, to the trailer
tow hitch. You could otherwise damage the
vehicle.
! Observe the following points when towing
with a tow rope:
R Secure the tow rope on the same side on
both vehicles.
R Make sure that the tow rope is not longer
than legally permitted. Mark the tow rope
in the middle, e.g. with a white cloth
(30 x 30 cm). This will make other road
users aware that a vehicle is being
towed.
R Only secure the tow cable to the towing
eyes or, if available, to the trailer tow
hitch.
R Observe the brake lamps of the towing
vehicle while driving. Always maintain a
distance a distance so that the tow rope does not sag.
R Do not use steel cables or chains to tow
your vehicle. You could otherwise dam-
age the vehicle.
! Do not use the trailer tow hitch for recov-
ery or towing. Do not use the towing eye for recovery. This could damage the vehicle. If
in doubt, have the vehicle recovered using
a crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged. !

Nand
do not open the driver's or front passeng-
er's door during towing. The automatic
transmission may otherwise shift to posi-
tion P, which could damage the transmis-
sion.
! You may tow the vehicle for a maximum of
50km. A towing speed of 50 km/h must not
be exceeded.
For towing distances over 50 km, the entire
vehicle must be lifted up and transported.
Observe the legal requirements for the rele-
vant countries when towing.
It is better to have the vehicle transported
than to have it towed.
If the vehicle has suffered transmission dam- age, have it transported on a transporter or
trailer.
The automatic transmission must be in posi-
tion Nwhen the vehicle is being towed away.
If the automatic transmission cannot be shif- ted to position N, have the vehicle transpor-
ted on a transporter or trailer.
The battery must be connected and charged.
Otherwise, you:
R cannot turn the key to position 2in the
ignition lock
R cannot release the electric parking brake
R cannot shift the automatic transmission to
position N
Deactivate the automatic locking feature
before towing the vehicle (Y page 102). You
could otherwise be locked out when pushing
or towing the vehicle.
Deactivate tow-away protection before tow-
ing away the vehicle (Y page 91).

If the vehicle is in a dangerous location it may
be towed from the danger zone with both
axles on the ground. In this case, the towing
distance may not be greater than 50 m and
the towing speed must not exceed 10 km/h.
For longer distances, have the vehicle loaded
and transported. Fitting/removing the towing eye
Fitting the towing eye The mountings for the removable towing eyes
are located in the bumpers. They are at the
front and at the rear under covers :.
Vehicles with a trailer tow hitch do not have a
bracket at the back for the screw-in towing
eye. Connect the towbar to the trailer tow
hitch (Y page 303).
X Take the towing eye out of the stowage well
on the left, under the luggage compartment floor (Y page 432).
X Press the mark on cover :inwards and
remove.
X Screw in the towing eye clockwise as far as
it will go and tighten it. Removing the towing eye X
Loosen the towing eye and unscrew it.
X Attach cover :to the bumper and press

The automatic transmission automatically
shifts to position Pwhen you open the driver's
or front-passenger door or when you remove the key from the ignition lock. In order to
ensure that the automatic transmission stays
in position Nwhen towing away the vehicle,
you must observe the following points:
X Make sure that the vehicle is stationary.
X Turn the key to position 2in the ignition
lock.
X Depress the brake pedal and keep it
depressed.
X Shift the automatic transmission to posi-
tion N.

does not permit any reliable conclusion about
the tyre pressure. On vehicles fitted with the
electronic tyre pressure monitor, the tyre
pressure can be checked using the on-board
computer.
If possible, only correct tyre pressures when
the tyres are cold.
The tyres are cold:
R if the vehicle has been parked with the tyres
out of direct sunlight for at least three
hours and
R if the vehicle has not been driven further
than 1.6 km
Depending on the ambient temperature, the
vehicle speed and the load on the tyres, the
tyre temperature and thus the tyre pressure
changes by approximately 10 kPa (0.1 bar/
1.5 psi) per 10 †. Take this into account
when checking the pressure of warm tyres.
Only correct the tyre pressure if it is too low
for the current operating conditions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have a negative effect on handling charac-
teristics and thus driving safety (e.g. aqua- planing)
The tyre pressure values given for low loads
are minimum values which offer you good ride
comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle. Tyre pressure loss warning system
General notes While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect significant pressure loss in a tyre. If the speed of rotation of a wheel changes as a result of a
loss of pressure, a corresponding warning
message will appear in the multifunction dis-
play.
You can recognise the tyre pressure loss
warning by the Run Flat Indicator
Run Flat Indicator
active active Restart with OK
Restart with OK message which
appears in the Service
Servicemenu of the multi-
function display. Information on the message display can be found in the "Restarting the
tyre pressure loss warning system" section
(Y page 460).
Important safety notes The tyre pressure warning system does not
warn you of an incorrectly set tyre pressure.
Observe the notes on the recommended tyre pressure (Y page 458).
The tyre pressure loss warning does not
replace the need to regularly check the tyre
pressures. An even loss of pressure on sev-
eral tyres at the same time cannot be detec-
ted by the tyre pressure loss warning system. The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering manoeuvres.
The function of the tyre pressure loss warning system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt a very sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towing a very heavy or large trailer.
R you are driving with a heavy load (in the
vehicle or on the roof). Tyre pressure
