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 Driver Information Centre 3 102.
When vehicle speed reaches 50 km/h, the system switches
automatically from Enhanced
Traction function to TC operation.

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 99 illuminates together
with A 3 97 in the instrument cluster
and a corresponding message
appears in the Driver Information
Centre 3 102.
The Traction control system (TC) is
not operational. Have the cause of the fault remedied by a workshop.
Vehicle messages 3 103.
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.
158Driving and operatingAs soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the wheels 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 3 102.
When ESP® Plus
comes into action b

Driving and operating171Trailer 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 80 km/h 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 3 246.
Trailer towing
Trailer loads The 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 sealevel. Since engine power decreases as altitude increases due to the airbecoming 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
3 225.
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.
172Driving and operatingIn 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) 3 157.Auxiliary features
Power take-off
Activation
To activate the power take-off, with
the vehicle stationary and the engine
idling:
● Set the gearshift lever to neutral (vehicles with manual
transmission automated:
selector lever in position N).
● Depress the clutch pedal.
Vehicle care2019Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
Temperature dependency
Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
Tyre pressure values provided on the
tyre information label and tyre
pressure chart are valid for cold tyres, which means at 20 °C. The pressure
increases by nearly 10 kPa (0.1 bar)
for a 10 °C temperature increase.
This must be considered when warm
tyres are checked.
Trailer towing
When towing a trailer with a fully laden vehicle, the tyre pressure must
be increased by 20 kPa/0.2 bar
(3.0 psi) and the maximum speed
limited to 100 km/h.
Trailer towing 3 171.
Rear-wheel drive, with twin rear
wheels
When inflating the outer tyre, the
inflation tube should be passed
between the two wheels.
Tyre pressure monitoringsystem
The tyre pressure monitoring system
uses radio and sensor technology to
check tyre pressure levels.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Note
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The tyre pressure monitoring system
sensors monitor the air pressure in
the tyres and transmit tyre pressure
readings to a receiver located in the
vehicle.
Tyre pressure chart 3 246.

operation, mountain driving, driving
on poor and sandy road surfaces,
increased air pollution, presence of
airborne sand and high dust content,

these severe operating conditions,
certain service work may be required
more frequently than the regular
service interval.

Confirmations Confirmation of service is recorded inthe Service and warranty booklet.
The date and mileage is completed
with the stamp and signature of the
servicing workshop.
Make sure that the Service and
warranty booklet is completed
correctly as continuous proof of
service is essential if any warranty or
goodwill claims are to be met, and is
also a benefit when selling the
vehicle.Service display
The service interval is based on
several parameters depending on
usage.
The service display, located in the

Recommended fluids andlubricants
Only use products that meet the
recommended specifications.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
