9 Warning
When refuelling, switch off the
remote control unit as well as the
heater!
The remote control has a maximum
range of 1000 metres. The range may
be reduced due to environmental
conditions and as the battery
becomes weaker.
In addition to a remote control unit,
the heating can also be switched on
for 30 minutes, or off, using the button on the instrument panel.
Battery replacement
Replace the battery when the range
of the remote control is reduced or
when the battery charge symbol
flashes.
Open the cover and replace the
battery (Type A: CR 2430, Type B:
2CR 11108, or equivalent), ensuring
the new battery is correctly installed
with the positive ( <) side facing the
positive terminals. Replace the cover
securely.
Dispose of old batteries in
accordance with environmental
regulations.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.

150Driving and operating● the rear doors/tailgate are notclosed correctly
● the vehicle had a rear-end accident
● there are extreme temperature changes
Lane departure warning The lane departure warning system
uses a front camera to observe the
lane markings between which the
vehicle is driving. The system detects
lane changes and warns the driver in
the event of an unintended lane
change via visual and acoustic
signals.
Criteria for the detection of an
unintended lane change are:
● no operation of turn and lane- change signals
● no active steering
If the driver is performing these
actions, no warning will be issued.Activation
The lane departure warning system is activated by pressing ì in the roof
console; LED in the button
extinguishes to indicate that the
system is switched on.
When control indicator ì 3 88
illuminates in the instrument cluster,
the system is ready to operate. A
corresponding message also
appears in the Driver Information
Centre (DIC) 3 92.
Control indicator ì extinguishes
when the system is not ready to warn the driver.
The system is only operable at
vehicle speeds above approx.
37 mph and if lane markings are
available and detected.
If the turn and lane-change signals
are not operated when changing
lanes, i.e. an unintended lane change

154Driving and operatingIf the trailer starts snaking, drive moreslowly, 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 3 225.
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 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
3 204.
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.
Page 157 of 239

Driving and operating155The 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) 3 141.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.
● Press switch on the instrument panel; LED in switch illuminatesafter approx. 2 seconds.
● Release the clutch pedal.
The engine idle speed increases to
1,200 rpm.Caution
During operation of the power
take-off, never move the selector
lever out of neutral (vehicles with
manual transmission automated:
selector lever in position N), to
avoid damage to the transmission.
If a gear change becomes
necessary, i.e. to adjust the driving
speed, the power take-off must always be deactivated first.
Deactivation
To deactivate the power take-off: ● Depress the clutch pedal.
● Press switch on the instrument panel; LED in switch
extinguishes after approx.
2 seconds.
● Release the clutch pedal.
