Emergencies
If you choose to change the engine compart-
ment l
amp
s yourself, remember that it is a
dangerous area ››› in Working in the en-
gine c omp
ar

tment on page 270.
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*
● Halogen headlights with LED daytime run-
ning lights*
● Re

ar 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. ●
Bef or

e changing a bulb, make sure you
have the correct 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.
● Depending on the level of equipment fitted
in the vehic
le, LEDs may be used for part or
all of the interior and/or exterior lighting.
LEDs have an estimated life that exceeds than
that of the car. If an LED light fails, go to an
authorised workshop for its replacement. 104

lutions per minute ››› Fig. 122 1 .
Tog ether w
ith the gear-change indicator, the
rev counter offers you the possibility of using
the engine of your vehicle at a suitable
speed.
The start of the red zone on the dial indicates
the maximum engine speed which may be
used briefly when the engine is warm and af-
ter it has been run in properly. Before reach-
ing this range, you should change to a higher
gear for vehicles with a manual gearbox or for
automatic gearboxes put the selector lever in
“D” or take your foot off the accelerator ped-
al.
We recommend that you avoid high revs and
that you follow the recommendations on the
gear-change indicator. Consult the additional
information in ›››

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 127 ,
● lock on driver door (emergency opening
›››
 page 15) or
● interior central locking switch ›››

page 128.
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 128.
Auto Lock*
The Auto Lock function locks the doors and
the rear lid when the vehicle exceeds a speed
of about 15 km/h (9 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 128.
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. After a certain 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 135.
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 128.
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. » 125
