When starting the engine or whilst driving
Only one warning chime will sound at a time.The warning chime regarding
unfastened seat belts has priority
over any other warning chime.
● If the door or bonnet is open.
● If seat belt is not fastened.
● If a certain speed is exceeded with parking brake applied.
● If a warning message or a warning code appears in the
Driver Information Centre.
● If the parking assist detects an object.
● If the fuel level is low.
When the vehicle is parked and/or the driver's door is opened
● With exterior lights on.
During an Autostop ● If the driver's door is opened.
Battery voltage
When the battery voltage is running
low, a warning message or warning
code 174 will appear in the Driver
Information Centre.1. Switch off immediately any electrical consumers which are
not required for a safe ride, e.g.
seat heating, heated rear window or other main consumers.
2. Charge the battery by driving continuously for a while or by
using a charging device.
The warning message or warning
code will disappear after the engine
has been started twice consecutively
without a voltage drop.
If the battery cannot be recharged,
have the cause of the fault remedied
by a workshop.
Driving and operating159Trailer 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, 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
and caravan trailers with a permitted
gross vehicle weight of more than
1000 kg a speed of 80 km/h 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 3 218.Trailer towing
Trailer loadsThe 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).
