196Driving and operatingTo close, turn the fuel filler cap
clockwise until it clicks.
Close the flap and allow it to engage.
Fuel filler cap
Only use genuine fuel filler caps.
Diesel-engined vehicles have special fuel filler caps.Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle. If
using non-factory fitted towing
equipment, deactivation of the hands- free tailgate operation may be
required 3 30.
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 bulbs with a power of 5 W each,
the function only detects lamp outage when only a single 5 W lamp remains
or none remain.
Trailers equipped with LED lights are
not suitable for the wiring harness of
this trailer hitch.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ballbar for towing. Always keep the
coupling ball bar in the vehicle to have it on hand if needed.
Driving characteristics andtowing 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.
During trailer towing do not exceed a
speed of 80 km/h. A maximum speed
of 100 km/h is only appropriate if an
oscillation damper is used and the
permissible gross trailer weight does
not exceed the vehicle’s curb weight.
For trailers with low driving stability
and caravan trailers, the use of an
oscillation damper is strongly
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.

Vehicle care211Tail lights
Tail lights, daytime running lights and
centre high-mounted brake light are
designed as LEDs. In case of failure, have LEDs replaced by a workshop.

To avoid losing the nut if it drops
into the wing trim, first place a
cloth below it.
3. Manually unscrew and remove the lamp fixing nut.
4. Disengage the retaining clip, while pushing the lamp out
slightly.5. From the outside, carefully withdraw the light assembly from
