Driving and operating151Fault9Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
Manual parking brake9 Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, depress the
brake pedal at the same time.
Control indicator R 3 93.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Hill start assist
The system helps prevent unintended movement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, the brakes
remain on for a further two seconds.
The brakes release automatically as

152Driving and operatingsoon as the vehicle begins to
accelerate or the two seconds holding
time is over.
The hill start assist is not active during
an Autostop.Ride control systems
Traction Control system
The Traction Control system (TC) is a component of the Electronic Stability
Control (ESC).
TC 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 start 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 after each engine
start as soon as the control indicator
b extinguishes.
When TC operates b flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Deactivation
TC can be switched off when spinning of drive wheels is required: press b
briefly.
A status message appears in the
Driver Information Centre when TC is
deactivated.

Driving and operating155DeactivationPress B; LED in the button
extinguishes and a message pops-up
in the Driver Information Centre.
Each time the engine is started, City
mode is deactivated.
Fault
In the event of a fault in the system,
control indicator c illuminates and a
message is displayed in the Driver
Information Centre.
Vehicle messages 3 103.
System calibration
If control indicators c and b
illuminate simultaneously, a
calibration of the power steering
system is necessary. This can occur
e.g. when turning the steering wheel
for one rotation with ignition switched
off. In this case, switch on ignition and turn steering wheel once from lock to
lock.
If control indicators c and b do not
extinguish after calibration, seek the
assistance of a workshop.Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds of approx. 20 mph to maximum vehicle speed. Deviations
from the stored speeds may occur
when driving uphill or downhill.
For safety reasons, the cruise control cannot be activated until the brake
pedal has been operated once.
Activating in first gear is not possible.

Driving and operating157DeactivationPress y; control indicator m in
instrument cluster illuminates white.
Cruise control is deactivated. Last
stored speed remains in memory for
later speed resume.
Automatic deactivation: ● Vehicle speed is below approx. 20 mph.
● Vehicle speed drops more than 15 mph below the set speed.
● The brake pedal is depressed.
● The clutch pedal is depressed for
a few seconds.
● The selector lever is in N.
● Engine speed is in a very low range.
● The Traction Control system or Electronic Stability Control is
operating.
● Parking brake is applied.
● Simultaneous pressing RES/+
and brake pedal deactivates
cruise control and will delete stored speed.Resume stored speed
Turn thumb wheel to RES/+ at a
speed above 20 mph. The stored
speed will be obtained.
Switching off Press m, control indicator m in
instrument cluster extinguishes. The
stored speed is deleted.
Pressing L to activate the speed
limiter or switching off the ignition also switches off cruise control and
deletes the stored speed.
Speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum
speed.
The maximum speed can be set at
speeds above 15 mph up to
125 mph.
The driver can only accelerate up to
the preset speed. Deviations from the
limited speed may occur when driving downhill.The preset speed limit is displayed in
the Driver Information Centre when
the system is active.
Activation
Press L. If cruise control has been
activated before, it is switched off when speed limiter is activated and
the control indicator m extinguishes.
Set speed limit Accelerate to the desired speed and
briefly turn thumb wheel to SET/-: the
current speed is stored as maximum
speed. Speed limit is displayed in the Driver Information Centre.

Driving and operating185Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
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.
The bulb outage detection function for trailer brake light cannot detect a
partial bulb outage, e.g. in case of four
times five watt bulbs, the function only detects lamp outage when only a
single five Watt lamp remains or none remain.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ball
bar for towing. Always keep the
coupling ball bar in the vehicle when
not in use.Driving characteristics and
towing tips
Before attaching a trailer, lubricatethe 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
and caravan trailers with a permitted
gross vehicle weight of more than
1000 kg a speed of 50 mph must not
be exceeded; the use of a stabiliser is
recommended.
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 3 254.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 loads apply up to
the specified incline and up to an
altitude of 1000 metres above sea
level. 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).
