Never u se a f
use with a higher value. Only
replace fuses with a fuse of the same amper-
age (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple
or simil
ar. CAUTION
● To pr ev

ent damage to the vehicle's electric
system, before replacing a fuse always turn
off the ignition, the lights and all electrical
elements and remove the key from the igni-
tion.
● If you replace a fuse with higher-rating
fuse,
you could cause damage to another part
of the electrical system.
● Protect the fuse boxes when open to pre-
vent the entr
y of dust or humidity as they can
damage the electrical system. Note
● One component m

ay have more than one
fuse.
● Several components may run on a single
fuse. Vehicle fuses

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 fo
llowing tables.
● Some of the equipment listed in the tables
below pert
ain only to certain versions of the

Changing bulbs requires a certain degree of
practical skill.
If you choose to change the engine compart-
ment lamps yourself, remember that it is a
dangerous area ››› in Work in the engine
c omp
ar

tment on page 246.
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 diff

erent sets of headlights and tail
lights:
● Halogen headlights
● Full-LED main headlights*
● Rear bulb light
● LED rear light*
Ful
l-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 p

articular care when working on com-
ponents in the engine compartment if the en-
gine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injure
yourself on sharp edges, in particu-
lar on the headlight housing. CAUTION
● Remo v

e the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights and the parking light
before c
hanging a bulb.
● Take good care to avoid damaging any com-
ponents. For the sake of the environment
Please ask your specialist retailer how to dis-
pose of u

sed bulbs in the proper manner. Note
● Ple a

se 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
have the c
orrect new bulb.
● Do not touch the glass part of the bulb with
your bar
e hands, use a cloth or paper towel
instead, since the fingerprints left on the
glass will vaporise as a result of the heat gen-
erated by the bulb, they will be deposited on
the reflector and will impair its surface. 94

orks when the ignition is
switched on. In order to avoid engine dam-
age, please read the following notes for the
different temperature ranges. Engine cold
If on
ly

the diodes in the lower part of the
scale light up, this indicates that the engine
has not yet reached operating temperature.
Avoid high revs and heavy acceleration and
do not make the engine work hard.
Normal temperature
If in normal operations, the diodes light up
until the central zone, it means that the en-
gine has reached operating temperature. At
high outside temperatures and when making
the engine work hard, the diodes may contin-
ue lighting up and reach the upper zone. This
is no cause for concern, provided the control
lamp  does not light up on the instrument
panel digital display.
Heat range
When the diodes light up in the upper area of
the display and the control lamp appears 
on the instrument panel display, the coolant
temperature is excessive ››› page 250. CAUTION
● To en s

ure a long useful life for the engine,
avoid high revs, driving at high speed and
making the engine work hard for approxi-
mately the first 15 minutes when the engine
is cold. The phase until the engine is warm al-
so depends on the outside temperature. If
necessary, use the engine oil temperature*

Operation
●
Addition a
l lights and other accessories in
front of the air inlet reduce the cooling effect
of the coolant. At high outside temperatures
and high engine loads, there is a risk of the
engine overheating.
● The front spoiler also ensures proper distri-
bution of the c
ooling air when the vehicle is
moving. If the spoiler is damaged this can re-
duce the cooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel - Gas level

The green warning lamp  lights up when the
vehicle is running in natural gas operating
mode.
The green warning lamp  switches off when
the natural gas is exhausted. The engine
changes to operate with petrol.
Problem: If the vehicle is left parked for a
long time immediately after refuelling, the
natural gas level indicator may not accurately
indicate the same level shown after refuelling
when the vehicle is started up again. This is
not due to a leak in the system, but to a drop
in pressure in the gas tank for technical rea-
sons after a cooling phase just after refuel-
ling.

ages.
● Stop the vehicle safely as soon as possible.
● Park the vehicle away from traffic and en-
sure th
at there are no highly flammable ma-
terials under the vehicle that could come into
contact with the exhaust system (e.g. dry
grass, fuel).
● A faulty vehicle represents a risk of acci-
dent for the driv
er and for other road users. If
necessary, switch on the hazard warning
lamps and put out the warning triangle to ad-
vise other drivers.
● Before opening the bonnet, switch off the
engine and al
low it to cool. ●
In any

vehicle, the engine compartment is a
hazardous area and could cause severe inju-
ries ››› page 246. CAUTION

Description Read the additional information carefully
›› ›

 page 11
The vehicle can be locked and unlocked via
the central locking system. There are several
methods, depending on the vehicle equip-
ment:
● key with remote control ››
›

page 118 ,
● lock on driver door (emergency opening
›››
 page 11) or
● interior central locking switch ›››

page 119.
Unlocking one side of the vehicle only
When you lock the vehicle with the key, the
doors and the rear lid are locked. When you
open the door, you can either unlock only the
driver door, or all the vehicle doors. To select
the required option, use Easy Connect*
››› page 119.
Automatic locking (Auto Lock)*
The Auto Lock function locks the doors and
the rear lid when the vehicle exceeds a speed
of about 15 km/h (10 mph). The vehicle is unlocked again when the igni-
tion key i

s removed. Alternatively, the vehicle
can also be unlocked via the central locking
switch or by pulling one of the inside door
handles. The Auto Lock function can be
switched on and off on the sound system or
on the Easy Connect* system ››› page 119.
In the event of an accident in which the air-
bags inflate, the doors will be automatically
unlocked to facilitate access and assistance.
Anti-theft alarm system*
If the anti-theft alarm system senses interfer-
ence with the vehicle it triggers an audible
and visible alarm.
The anti-theft alarm system is automatically
switched on when locking the vehicle. It
switches off when the vehicle is unlocked
from a distance.
When the driver door is unlocked with the
key, you should switch on the ignition within
15 seconds. Otherwise the alarm will be trig-
gered. On some export versions, the alarm is
triggered immediately when you open a door.
To deactivate the alarm, press the button  on the remote control key, or switch on the
ignition. Af
t
er a c

ertain time, the alarm will
automatically switch off.
Switch off the vehicle interior monitoring and
tow-away protection if you wish to prevent the alarm from being triggered accidentally
›››
page 123.
Turn signals
The turn signals will flash twice when the ve-
hicle is unlocked and once when the vehicle
is locked.
If it does not flash, this indicates that one of
the doors, the rear lid or the bonnet is not
closed correctly.
Accidental lock-out
The central locking system prevents you from
being locked out of the vehicle in the follow-
ing situations: ● If the driver door is open, the vehicle can-
not be lock
ed with the central locking switch
››› page 119.
Lock the vehicle with the remote control key,
when all the doors and the rear lid have been
closed. This prevents the accidental locking
of the vehicle. WARNING
Do not leave anyone (especially children) in
the v ehic

le if it is locked from the outside and
the anti-theft security system* is enabled, as
the doors and windows cannot then be
opened from the inside. Locked doors could
delay assistance in an emergency, potentially
putting lives at risk. 116
