What to do first ●
Park the vehicle on a horizontal surface
and in a s af
e place as far away from traffic as
possible.
● Apply the handbrake.
● Switch on the hazard warning lights.
● Manual gearbox: select
the 1st gear.
● Automatic gearbox: Mov
e the selector lever
to position P.
● If you are towing a trailer, unhitch it from
your
vehicle. ●
Have the
vehicle tool kit ›››

and the spare wheel* ready
››› page 298.
● Observe the applicable legislation for each
cou
ntry (reflective vest, warning triangles,
etc.).
● All occupants should leave the vehicle and
wait
in a safe place (for instance behind the
roadside crash barrier). WARNING
● Alw
ays observe the above steps and pro-
tect yourself and other road users.

Emergencies
CAUTION
● The t o
wing eye must always be completely
and firmly tightened. Otherwise, it could be
released while towing and tow-starting.
● If the vehicle is factory-equipped with a
to
wing bracket, it is only allowed to tow with
a tow bar if this has been specially designed
to be installed with a tow hitch. If an unsuita-
ble tow bar is used, both the tow hitch and
the vehicle may be damaged. Instead, a tow
rope should be used. Driving tips for towing
Towing requires some expertise and experi-
enc
e, e
specially when using a tow rope. Both
drivers should be familiar with the difficulties
involved in towing. For this reason, inexper-
ienced drivers should abstain from towing.
During towing, it should be ensured that no
impermissible tractive forces or shocks are
generated. When towing on an unpaved
road, there is always a risk of overloading
and damaging the anchorage points.
During towing, the towing vehicle can signal
the change of direction even with the hazard
warning lights turned on. To do so, at the
same time, the turn signal lever must be op-
erated with ignition switched on. Meanwhile,
the hazard warning lights will go off. When
the turn signal lever is returned to the rest position, the hazard warning lights will be
autom
atically reactivated.
Notes for the driver of the towed vehicle ● Leave the ignition on, so that the steering
is
not blocked, and the electronic parking
brake may be deactivated and the turn sig-
nals and wash/wipe operated.
● More strength is required at the steering
wheel a
s the power steering does not oper-
ate when the engine is switched off.
● You should depress the brake much harder
as
the brake servo does not operate. Avoid
hitting the towing vehicle.
● Bear in mind the information and instruc-
tions
in the manual of the vehicle to be tow-
ed.
Notes for the driver of the towing vehicle
● Accelerate with particular care and caution.
Av
oid sharp manoeuvres.
● Brake earlier than usual and smoothly.
● Bear in mind the information and instruc-
tions
in the manual of the towed vehicle. Fuses and bulbs
F u
ses
Introduction In general, a fuse can be assigned to various
el
ectric
al components. Likewise, an electrical
component can be protected by several
fuses.
Only replace fuses when the cause of the
problem has been solved. If a newly inserted
fuse blows after a short time, you must have
the electrical system checked by a special-
ised workshop as soon as possible. WARNING
The high voltages in the electrical system can
giv e seriou
s electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion sys
tem.
● Take care not to cause short circuits in the
electric
al system. WARNING
Using unsuitable fuses, repairing fuses or
bridgin g a c
urrent circuit without fuses can
cause a fire and serious injury. 90
Fuses and bulbs
CAUTION
● Alw
ays carefully remove the fuse box cov-
ers and refit them correctly to avoid problems
with your vehicle.
● Protect the fuse boxes when open to avoid
the entry
of dust or humidity. Dirt and humid-
ity inside fuse boxes can cause damage to
the electrical system. Note
● In the v
ehicle, there are more fuses than
those indicated in this chapter. These should
only be changed by a specialised workshop.
● Positions not containing a fuse do not ap-
pear in the f
ollowing tables.
● Some of the equipment listed in the tables
below per
tain only to certain versions of the
model or are optional extras.
● Please note that the above lists, while cor-
rect

Changing bulbs requires a certain degree of
practical skill. If you choose to change the engine compart-
ment l
amps yourself, remember that it is a
dangerous area ››› in Work in the engine
c omp
artment on page 283.
Always use identical bulbs with the same
designation. The name can be found on the
base of the bulb holder.
Depending on how equipped the vehicle is,
there are different sets of headlights and tail
lights:
● Halogen headlights
● Full-LED main headlights*
● Rear bulb light
● LED rear light*
Fu
ll-LED headlight system*
Full-LED headlights handle all light functions
(daylight, side light, turn signal, dipped
beam and route light) with light emitting di-
odes (LEDs) as a light source.
Full-LED headlights are designed to last the
lifetime of the car and light bulbs cannot be
replaced. In case of headlight failure, go to
an authorised workshop to have it replaced. WARNING
● Tak
e particular care when working on com-
ponents in the engine compartment if the en-
gine is warm. Risk of burns. ●
Bu
lbs are highly sensitive to pressure. The
glass can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injur
e yourself on sharp edges, in particu-
lar on the headlight housing. CAUTION
● Remo
ve the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights and the parking light
befor

● Take good care to avoid damaging any com-
ponents. For the sake of the environment
Please ask your specialist retailer how to dis-
po se of
used bulbs in the proper manner. Note
● Ple
ase check at regular intervals that all
lighting (especially the exterior lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also that of all other road users.
● Before changing a bulb, make sure you
hav
e the correct new bulb.
● Do not touch the glass part of the bulb with

● Always use your dipped beam head lights if
it i
s raining or if visibility is poor. WARNING
If the headlights are set too high and not
u sed c
orrectly, there is a risk of dazzling or
distracting other road users. This could result
in a serious accident.
● Always make sure that the headlights are
corr
ectly adjusted. Daytime running lights
The daytime running lights consist of individ-
ual
lights, int
egrated in the front headlights.
By connecting the daytime running lights,
these lights are switched on 1)

6. Use the warning triangle to draw the atten- tion of other r
oad users to your vehicle.
7. Always take the vehicle key with you when you l
eave the vehicle.
All turn signals flash simultaneously when
the hazard warning lights are switched on.
The two turn signal turn signal lamps
and the turn signal lamp in the switch will
flash at the same time. The simultaneous
hazard warning lights also work when the ig-
nition is switched off.
Emergency braking warning
If the vehicle brakes suddenly and continu-
ously at a speed of more than 80 km/h (50
mph), the brake light flashes several times
per second to warn the vehicles driving be-
hind. If you continue braking, the hazard
warning lights will come on automatically
when the vehicle comes to a standstill. They
switch off automatically when the vehicle
starts to move again. WARNING
● The ri sk
of an accident increases if your ve-
hicle breaks down. Always use the hazard
warning lights and a warning triangle to draw
the attention of other road users to your sta-
tionary vehicle.
● Due to the high temperatures that the cata-
lytic c
onverter can reach, never park in an
area where the catalytic converter could come into contact with highly inflammable materi-
a
l
s, for example dry grass or spilt petrol. This
could start a fire. Note
● The b att
ery will run down if the hazard
warning lights are left on for a long time,
even if the ignition is switched off.
● The use of the hazard warning lights de-
sc
ribed here is subject to the relevant statu-
tory requirements. Parking lights
When the parking light is switched on, (right
or l
ef
t turn signal), the front side light and
the rear light on the corresponding side of
the vehicle stay lit. The parking lights can on-
ly be activated with the ignition switched off
and the turn signal and main beam lever in
the central position, before being triggered.
Parking light on both sides With the ignition switched off and the light
sw
it
ch in position , when locking the vehi-
cle from the outside, the parking lights on
both sides of the vehicle light up. In doing
so, only the side lights of both headlights
light up, and additionally the tail lights will
do so partially. Motorway light* The motorway light is available on vehicles
equip
ped w
ith full-LED lights.
The function is connected/disconnected via
the corresponding Easy Connect system
menu.
● Activation: when goin
g above 110 km/h
(68 mph) for more than 30 seconds, the dip-
ped beam raises slightly to increase the driv-
er's visibility distance.
● Deactivation: when r educ
ing the speed of
the car below 100 km/h (62 mph), the dip-
ped beam returns to its normal position.
Driving abroad The light beam of the dipped beam lights is
a
symmetric: the s
ide of the road on which
you are driving is lit more intensely.
When a car that is manufactured in a country
that drives on the right travels to a country
that drives on the left (or vice versa), it is nor-
mally necessary to cover part of the headlight
bulbs with stickers or to change the adjust-
ment of the headlights to avoid dazzling oth-
er drivers.
In such cases, the regulations specify certain
light values that must be complied with for
designated points of the light distribution.
This is known as “Tourist light”.
