Towing bracket device
CAUTION
● If anything is attached to the tow hitch ball,
do not, under any circumstances press the
button.
● Never direct a high-pressure or steam
cleaning system directly at the tow hitch ball
or trailer power socket. This could cause
damage to seals or remove lubricating
grease. Note
In extremely low temperatures, it is possible
that the tow hitch is not released. In this
case, place the vehicle in a warmer location
(e.g. a garage). Installing a bicycle carrier to the tow
hitch
The maximum load permitted for a bicycle
carrier on the tow hitch ball is
75 kg, with a
m ax
imum distance of 30 cm from the sup-
port. The distance between supports is the
distance between the bicycle carrier centre of
gravity (with the bicycles) and the centre of
point of the tow hitch ball. WARNING
The incorrect use of the tow hitch with a bicy-
cle carrier installed can cause accidents and
injury. ●
Never exceed the load and distances be-
tween supports indicated.
● Never fit the bicycle carrier to the tow hitch
ball neck, underneath the tow hitch given
that the bicycle carrier may be incorrectly fit-
ted due to the shape of the tow hitch and the
model of bicycle carrier.
● Always read and take the manufacturer as-
sembly instructions into account. CAUTION
Exceeding the maximum load and distance
between supports indicated can cause con-
siderable damage to the vehicle.
● Never exceed the specifications. Hitching and connecting the trailer

Fuses and bulbs
WARNING
Failure to replace bulbs correctly may cause
serious accidents.
● Before carrying out any work in the engine
compartment please read and observe the
warnings ››› page 214. In any vehicle, the en-
gine c omp
artment is a hazardous area and
could cause severe injury.
● Discharge lamps work with high-voltage
and can cause serious or fatal injury if han-
dled incorrectly.
● H7 and discharge lamps are highly pressur-
ised and could explode when being changed.
● Only replace the bulbs concerned when
they have cooled.
● Never replace bulbs alone if you are not fa-
miliar with the operations necessary. If you
are not sure about procedures then visit a
specialised workshop to carry out the neces-
sary work.
● Never touch the bulb glass directly. Finger-
prints will be evaporated by the heat of the
operating bulb thus “fogging” up the reflec-
tor.
● The headlamp frameworks in the engine
compartment and the tail lamps contain sharp elements. Always protect your hands
when changing bulbs.
CAUTION
● After changing a bulb, if the rubber covers
are not replaced correctly on the headlamp
framework, the electrical installation may be
damaged, especially if water is allowed to en-
ter.
● Remove the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights and the parking light
before changing a bulb.
● Take good care to avoid damaging any com-
ponents. Control lamp
It
lights upPossible causeSolution
A vehicle exterior
lighting bulb is not
working.Replace the faulty
bulb. Several warning and control lamps light up
for a few seconds when the ignition is switch-
ed on, signalling that the function is being
verified. They will switch off after a few sec-
onds.
Checking the bulbs of a trailer
For vehicles with the factory fitted towing
bracket, certain trailer lights are also control-
led if the power socket is correctly connected.
A fault on a trailer turn signal is indicated on
the instrument panel by the turn signal blink-
ing twice as fast (
or ) ››› page 74.
● General fault of all turn signals on one side.
● Fault in one tail light (on some models, al-
so the registration light).
● Fault in two brake lights. WARNING
Observe the safety warnings ››› in Control
and warning lamps on page 47. Note
A fault in the LED on the tail lights will not be
indicated. However, if the fault affects all the
LEDs then this will be indicated by the control
lamp . 267
