Tow-starting and towing away
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 voltage supply or the vehicle's electrical system.
If your vehicle is being towed, much more
force may be necessary to steer or brake.
There is a risk of an accident.
In such cases, use a tow bar. Before towing,
make sure that 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 permissible
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 vehicle,
its weight should not be greater than the per- missible gross weight of your vehicle.
Information on the gross vehicle weight can be
found on the vehicle identification plate
(
Ypage 276).
!Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could be
damaged.
!Observe the following points when towing
with a tow rope:
RSecure the tow rope on the same side on
both vehicles.
REnsure that the tow cable is not longer than
legally permitted. Mark the tow cable in the
middle, e.g. with a white cloth (30 x 30 cm).
This will make other road users aware that
the vehicle is being towed.
ROnly secure the tow cable to the towing
eye.
RObserve the brake lamps of the towing
vehicle while driving. Always maintain a dis-
tance so that the tow rope does not sag.
RDo not use steel cables or chains to tow
your vehicle. You could otherwise damage
the vehicle.
!Do not use the towing eye for recovery, this
could damage the vehicle. If in doubt, recover
the vehicle with a crane.
!When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.
When towing away, you must observe the legal
requirements for the country in which you are
currently driving.
It is preferable to have the vehicle transported
on a transporter or trailer instead of towing it.

RDo not drive with tires which have too little
tread depth, as this significantly reduces the
traction on wet roads (hydroplaning).
RReplace the tires after six years at the latest,
regardless of wear. This also applies to the
spare wheel.
Operation in winter
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Prior to the onset of winter, ensure that snow
chains are stowed in the vehicle (
Ypage 251).
Also observe the notes in the "Changing a
wheel" section (
Ypage 267).
Regularly check the vehicle and remove snow or
ice when traveling in wintry conditions.
An accumulation of snow and ice, particularly
when frozen, caught in the area around the air
intake slots, moving parts, the axles and the
wheel arches may:
Rrestrict air intake
Rdamage vehicle parts
Rcause malfunctions by restricting the mobility
intended by the design (e.g. reduced possible
steering input).
If there is any damage, inform a qualified spe-
cialist workshop.
Driving with summer tires
At temperatures below 45 ‡ (+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehicle
to M+S tire. Using summer tires at very cold
temperatures could cause tears to form,
thereby damaging the tires permanently. We
cannot accept responsibility for this type of
damage.
M+S tires
GWARNING
Wheel and tire dimensions as well as the type of tire can vary between the spare wheel and
the wheel to be replaced. When the spare
wheel is mounted, driving characteristics may
be severely affected. There is a risk of an acci- dent.
In order to reduce risks:
Ryou should therefore adapt your driving
style and drive carefully.
Rnever mount more than one spare wheel
that differs from the wheel to be replaced.
Ronly use a spare wheel that differs from the
wheel to be replaced for a short time.
Rdo not deactivate ESP®.
Rhave a spare wheel that differs from the
wheel that has been changed replaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tire dimensions as well as the wheel type.
GWARNING
M+S tires with a tire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident.
M+S tires with a tread depth of less than ãin
(4 mm) must be replaced immediately.
Use winter tires or all-season tires at tempera-
tures below 45 ‡ (+7 †). Both types of tire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions.
Only these tires will allow driving safety systems
such as ABS and ESP
®to function optimally in
winter. These tires have been developed specif-
ically for driving in snow.
For safe driving, use M+S tire sof the same make
and tread pattern on all wheels.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
If you install M+S tires that have a lower maxi-
mum permissible speed than the maximum per-
missible speed of the vehicle, affix an appropri-
ate warning sign in the driver's field of vision.
You can obtain this at a qualified specialist work-
shop.
250Operation in winter
Wheels and tires
flated tire causes the tire to overheat and canlead to tire failure. Underinflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stop-
ping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
USA only:
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate if the
system is not operating properly. The TPMS
malfunction indicator is combined with the
low tire pressure telltale. When the system
detects a malfunction, the warning lamp will
flash for approximately a minute and then
remain continuously illuminated. This
sequence will be repeated every time the vehi-
cle is started as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the mounting of incompatible
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from func-
tioning properly. Always check the TPMS mal-
function telltale after replacing one or more
tires or wheels on your vehicle to ensure that
the replacement or alternate tires and wheels
allow the TPMS to continue to function prop-
erly.
Vehicles with a tire pressure monitor are equip-
ped with sensors in the wheels that monitor the
tire pressure of all four tires. The tire pressure
monitor monitors the pressure in all four tires;
you set this pressure when you activate the tire pressure monitor. The tire pressure monitor
warns you when the pressure drops in one or
more of the ti
res. The tire pressure monitor only
functions if the corresponding sensors are
installed on all wheels. You should always adjust the tire pressure
according to the vehicle load. Restart the tire
pressure monitor if you change the tire pres-
sure.
The tire pressure monitor does not warn you if a
tire pressure is incorrect. Observe the notes on the recommended tire pressure (
Ypage 251).
The tire pressure monitor is not able to warn you
of a sudden loss of pressure, e.g. following pen- etration by a foreign object. In this event, brake
the vehicle until it comes to a standstill. Do not
carry out any sudden steering maneuvers.
The tire pressure monitor has a yellow h
warning lamp in the instrument cluster for indi-
cating pressure loss/malfunctions (USA) or
pressure loss (Canada). Depending on how the
warning lamp flashes or lights up, an underin-
flated tire or a malfunction in the tire pressure
monitor is displayed:
Rif the h warning lamp is lit continuously,
the tire pressure on one or more tires is sig-
nificantly too low. The tire pressure monitor is
not malfunctioning.
RUSA only: if the hwarning lamp flashes for
60 seconds and then remains lit constantly,
the tire pressure monitor is malfunctioning.
Only vehicles with steering wheel buttons: the
on-board computer displays information on tire
pressure. After a few minutes of driving, the cur-
rent tire pressure of each tire is shown in the on-
board computer.
USA only: if the tire pressure monitor is mal-
functioning, it may be more than 10 minutes
before the malfunction is shown. The htire
pressure warning lamp flashes for 60 seconds
and then remains lit. When the malfunction has been rectified, the htire pressure warning
lam p goes ou
t after a few minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure 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 a pressure gauge are higher than those shown by
the on-board computer. In this case, do not
reduce the tire pressures.
If radio transmitting equipment (e.g. wireless
headphones, two-way radios) is operated inside
the vehicle or in the vicinity of the vehicle, this
can interfere with the operation of the tire pres-
sure monitor.

Rchanged the tire pressure
Rchanged wheels or tires
Rinstalled new wheels or tires
However, you can also define reference values
manually as described here.
