Flashes if a turn signal or the hazard
warning flashers are activated.
Rapid flashing: failure of a turn signal
light or associated fuse.
An audible warning can be heard
when the turn signals are on. When
towing a trailer, the pitch of the
audible warning changes.

feature tempt you into taking risks
when driving.

Enhanced Traction function
If necessary, in the event of soft
ground, mud or snow-covered road
surfaces, the Traction control system
(TC) can be deactivated to enhance
traction:
Press Ø on the instrument panel.
Control indicator Ø illuminates in the
instrument cluster and a
corresponding message appears in
the DIC 3 89.
When vehicle speed reaches 30 mph, the system switches
automatically from Enhanced
Traction function to TC operation.
Control indicator Ø extinguishes in
the instrument cluster.
TC is reactivated by pressing Ø
again. Control indicator Ø
extinguishes.
TC is also reactivated the next time
the ignition is switched on.
Fault
If the system detects a fault, control indicator b 3 86 illuminates together
with A 3 85 in the instrument cluster
and a corresponding message
appears in the DIC 3 89.
The Traction control system (TC) is
not operational. Have the cause of the fault remedied by a workshop.
Vehicle messages 3 90.
Electronic stability program
The Electronic Stability Program
(ESP® Plus
) improves driving stability
when necessary, regardless of the type of road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the

138Driving and operatingwheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESP® Plus
is operational as soon as
the ignition is switched on and control
indicator b extinguishes in the
instrument cluster. A corresponding
message also appears in the Driver
Information Centre (DIC) 3 89.
When ESP® Plus
comes into action b

time the ignition is switched on.

150Driving and operatingGeneral information
The official fuel consumption and
specific CO 2 emission figures quoted
relate to the EU base model with
standard equipment.
Fuel consumption data and CO 2
emission data are determined
according to regulation
715/2007 692/2008 A, taking into
consideration the vehicle weight in
running order, as specified by the
regulation.
The figures must not be taken as a
guarantee for the actual fuel
consumption of a particular vehicle.
Additional equipment may result in
slightly higher results than the stated
consumption and CO 2 figures.
Furthermore, fuel consumption is
dependent on personal driving style
as well as road and traffic conditions.Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust fitting of towing equipment at
a later date to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Driving characteristics and towing tips
In the case of trailers with brakes,
attach the breakaway stopping cable.
Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce snaking movements. For trailers with
low driving stability the use of a
stabiliser is recommended.
A maximum speed of 50 mph must
not be exceeded, even in countries
where higher speeds are permitted.If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 219.
Trailer towing Trailer loadsThe permissible trailer loads are
vehicle-dependent and engine-
dependent maximum values which
must not be exceeded. The actual
trailer load is the difference between
the actual gross weight of the trailer
and the actual coupling socket load
with the trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In
general, they are valid for gradients
up to max. 12%.
The permitted trailer load applies up
to the specified incline and up to an
altitude of 1000 metres above sea

Driving and operating151level. Since engine power decreases
as altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10%
for every 1000 metres of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than
8%, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 199.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load is specified on the
towing equipment identification plate
and in the vehicle documents. Always aim for the maximum load, especially
in the case of heavy trailers. The
vertical coupling load should never
fall below 25 kg.In the case of trailer loads of
1200 kg or more, the vertical coupling load should not be less than 50 kg.
Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded (including
all occupants), the permissible rear
axle load (see identification plate or
vehicle documents) must not be
exceeded.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Towing equipment audible
warning
For vehicles fitted with towing
equipment, when connected to a
trailer the pitch of the audible warning
changes upon operation of the turn
signals.
The pitch of the audible warning will
change if a turn signal light on the
trailer or the towing vehicle fails.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While the system is working,keep steering wheel as still as
possible.
Trailer stability assist (TSA) is a
function of the Electronic Stability
Program (ESP) 3 137.
