Driving economically
ECO mode
ECO mode is a function that
optimises fuel consumption. It affects engine power and torque,
acceleration, gear shift indication,
heating, air conditioning and electrical consumers.
Activation
Press ECO. Control indicator ECO
illuminates in the instrument cluster when activated.
128Driving and operatingfor a further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.Caution
The Hill start assist cannot
completely prevent vehicle
movement in all situations
(extremely steep gradients, etc.).
If necessary, depress the brake
pedal to prevent the vehicle from
rolling forwards or backwards.
The Hill start assist is not active
during an Autostop. Stop-start system
3 117.
Ride control systems
Traction Control system The Traction Control system (TC) is a
component part of the Electronic
Stability Program (ESP® Plus
) which
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC 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 TC is active b flashes.9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.

Trailer stability assist (TSA) 3 141.
Enhanced Traction function
Driving and operating129If 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 F 3 85 in the instrument cluster
and a corresponding message
appears in the DIC 3 89.
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
wheels are braked individually. Thisconsiderably 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
flashes.9 Warning

feature tempt you into taking risks
when driving.

140Driving and operatingTrailer hitch
General information
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment. Only use
towing equipment that has been
approved for your vehicle.
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 thecoupling 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 3 196.
Trailer towing
Trailer loads The permissible trailer loads are
vehicle 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 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
3 184.
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.
Driving and operating141In the case of trailer loads of
1200 kg or more, the vertical coupling
load should not be less than 50 kg.
Rear axle loadWhen 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.
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® Plus
) 3 129.

176Vehicle careCaution
Do not tow the vehicle from the
rear. The front towing eye must
only be used for towing and not
recovering a vehicle.
Caution
Activate the child locks in the rear
doors if the rear seats are
occupied. Child locks 3 28.
Switch on ignition to permit operation
of brake lights, horn and windscreen
wipers, and move the steering wheel
slightly to release the steering wheel
lock.
Transmission in neutral.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust fumes
from the towing vehicle, switch on the air recirculation system 3 102 and
close the windows.
Seek the assistance of a workshop.
After towing, unscrew the towing eye
and replace cap.
Towing another vehicle
The fixed towing eye is located under the rear bumper.
Attach a tow rope - or better still a tow
rod - to the rear towing eye, never to
the rear axle and suspension units.
The rear towing eye must only be
used for towing and not recovering a
vehicle.Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
