Driving and operating153warning may sound as a signal to
depress the brake pedal or apply the
parking brake.
Switch off engine if stopping for a lengthy period, e.g. in traffic jams.
When the vehicle is parked and the
driver's door is opened, a warning
chime will sound if neutral is not
selected or the brake pedal has not
been depressed.
Engine braking
Automatic mode
When driving downhill, the manual transmission automated does not shift into higher gears until a fairly
high engine speed has been reached. It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect, select a lower gear in good time when driving downhill.Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud, snow or a hole. Move the
selector lever between R and A/M (or
between + and -) in a repeat pattern,
while applying light pressure to the
accelerator pedal. Do not race the
engine and avoid sudden
acceleration.
Parking
Apply the parking brake. The most recently engaged gear (see
transmission display) remains
engaged. With N, no gear is engaged.
When the ignition is switched off, the transmission no longer responds to
movement of the selector lever.
If the ignition is not switched off, or the parking brake has not been applied, a
warning chime will sound upon
opening the driver's door.
Manual mode If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, theshift is not executed. This prevents
the engine from running at too low or too high an engine speed.
If engine speed is too low, the
transmission automatically shifts to a
lower gear.
If engine speed is too high, the
transmission only switches to a higher gear via kickdown.

156Driving and operating9Warning
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.
If control indicators u, A , R and
C illuminate, the ABS and ESP are
deactivated and the message
BRAKING FAULT is shown in the
Driver Information Centre. Seek the
assistance of a workshop.
Have the cause of the fault remedied
by a workshop.
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 99.
Parking 3 140.
Retractable parking brake
Depending on vehicle, the parking
brake lever retracts to the horizontal
position even with the parking brake
applied.
To release the parking brake, press the release button and pull the lever
up slightly, then return the lever to the
horizontal position.
To apply the parking brake, pull the
lever up then release it. The lever
returns to the horizontal position.
172Driving and operatingTrailer 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 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 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 3 247.
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 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
3 226.
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 operating173In 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.
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) 3 158.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.
