98Unlocking and locking
Note
● While the driver door is open, the vehicle cannot be locked with the re-
mote control. This avoids the user from forgetting his key inside the vehicle.
● If the driver door is unlocked with the key shaft, only the driver door is
unlocked, the rest of the doors remain locked. When the ignition is switched
on, the door deadlock function is deactivated (although the doors remain
locked) and the central lock button is activated. See ⇒ page 106.
● If the central locking or anti-theft alarm are faulty, the driver door warn-
ing lamp remains lit for approx. 30 seconds after locking the vehicle.
● For anti-theft security, only the driver door is fitted with a lock cylinder. 
Safety system “Safe*”
The deadlock function makes it more difficult to break into
the vehicle because the door release lever and the central
lock button are not active (depending upon country). Activating deadlock
– Press once the locking button 
on the remote control. or
– Turn the key once in the driver door lock to lock. A warning lamp
in the driver door flashes to indicate the deadlock is working.
The warning lamp flashes for approx. two seconds at short in-
tervals and then more slowly.
Deactivating deadlock when the vehicle is locked
– Press the lock button 
on the remote control
twice within two
seconds. The vehicle is locked without activating the deadlock.
The driver door warning lamp flashes for approx. two seconds
and then goes out. After approx. 30 seconds it starts flashing
again. The doors can be unlocked and opened from the inside if the deadlock has
not been activated. You will have to pull the door release lever once. When
the deadlock is off, the anti-theft alarm*
⇒ page 106 remains active. The
vehicle interior monitoring system* and the anti-tow system are deactiva-
ted*.
WARNING
Nobody should remain in the vehicle if the anti-tow system deadlock
mechanism has been activated. It is not possible to open the doors from
the inside. Locked doors could make it more difficult to assist vehicle oc-
cupants in the event of an accident. People could become trapped inside
in an emergency.

Selective unlocking system*
This system allows to unlock either just the driver door or all
the vehicle.
Using the remote control, press the unlock button on the remote 
once.
The Safe system for all the vehicle is deactivated, only the driver door is un-
locked and both the alarm and the warning lamp are also turned off.
Unlocking all doors and the luggage compartment

so that
all doors and the luggage compartment can be opened.
Press twice within 2 seconds to deactivate the Safe system for all vehicle, to
unlock all doors and to use the luggage compartment. The warning lamp
and the alarm (only vehicles fitted with one) are turned off. 

106Unlocking and locking
Anti-theft alarm system*
Description of anti-theft alarm system*
The anti-theft alarm triggers if unauthorised movements are
detected around the vehicle.
The anti-theft alarm makes it more difficult to break into the vehicle or steal
it. Audible and visible alarms are triggered if the vehicle is opened using
the key, or if unauthorised access to the vehicle is forced.
The anti-theft alarm system is automatically connected on locking the vehi-
cle. The system is then primed.
When does the system trigger an alarm?
The system triggers an alarm if the following unauthorised actions are car-
ried out when the vehicle is locked:
● Mechanical opening of the vehicle with the vehicle key
● Opening a door
● Opening the bonnet
● Opening the tailgate
● Switching on the ignition
● Movements in the vehicle interior
● Undue manipulation of the alarm
● Battery handling
The acoustic signals sound and the turn signals flash for approx. 30 sec-
onds. This may be repeated up to 10 times depending on the country.
Opening the doors mechanically (emergency opening)
If the remote control function fails, you will have to use the key to unlock the
vehicle. This is done as follows: ●
Unfold the key by pressing the button shown by the (arrow).
● Use the lock on the driver door to unlock the vehicle. The anti-theft
alarm system remains active, but an alarm is not triggered immediately.
● Switch on the ignition within 15 seconds. When the ignition is switched
on, the electronic immobiliser recognises a valid vehicle key and deacti-
vates the anti-theft alarm system. If you do not switch on the ignition within
15 seconds, the alarm is triggered.
Opening all the doors in manual mode
In vehicles without alarm, when opening the driver door manually all the
doors are opened.
How to switch the alarm off
When the vehicle is unlocked via the unlocking button of the remote control
or when the key is inserted in the ignition lock.
Note
● If, after the alarm goes off, another monitored area is accessed (e.g. the
tailgate is opened after a door has been opened), the alarm is triggered
again.
● Vehicle monitoring remains active even if the battery is disconnected or
not working for any reason.
● The alarm is triggered immediately if one of the battery cables is discon-
nected while the alarm system is active. 
Volumetric sensor*
Monitoring or control function incorporated in the anti-theft
alarm* which detects unauthorized vehicle entry by means
of ultrasound.
The system consists of 3 sensors, 2 emitters and a receptor. 

107
Unlocking and locking
Activation
– It is automatically turned on with the anti-theft alarm, when the
vehicle is locked mechanically with the key and when the but-
ton 
on the remote control is used.
Deactivation
– Press the button 
on the remote control twice. Only the volu-
metric sensor is deactivated. The alarm system remains activa-
ted.
WARNING
● The Safe security system remains deactivated if the volumetric sen-
sor is deactivated.
● For those vehicles in which a separation screen is fitted, the alarm
will not function correctly due to interference with the sensor.
Note
● If the alarm has been triggered by the volumetric sensor, this will be in-
dicated by a flashing of the indicator on the driver door. This flashing will be
different to that for an activated alarm. 

126Lights and visibility
Intermittent wipe
–Move the lever up to position 1
.
– Move the control A
to the left or right to set the length of the
intervals. Control to the left: long intervals; control to the right:
short intervals. Four wiper interval stages can be set using
switch A
.
Slow wipe
– Move the lever up to position 2
.
Continuous wipe
– Move the lever up to position 3
.
Short wipe
– Move the lever down to position 4
to give the windscreen a
short wipe. The wiper will start to move faster if you keep the
lever pressed down for longer than two seconds.
Wash and wipe automatic system 
– Pull the lever towards the steering wheel - Position 5
. The
wash function will start immediately and the wipers will start
with a slight delay. The wash and wiper systems will function at
the same time at speeds of over 120 km/h.
– Release the lever. The wipers will keep running for approximate-
ly four seconds.
Heated windscreen in the wiper blade area*
In some countries and with some versions, there is the possibility of heat-
ing the windscreen in the area of the windscreen wiper blades in order to
aid de-icing in the zone. The function is switched on by pressing the heated
rear window key .
WARNING
● Worn and dirty wiper blades reduce visibility and safety levels while
driving.
● In cold conditions, you should not use the wash / wipe system unless
you have warmed the windscreen with the heating and ventilation sys-
tem. The washer fluid could otherwise freeze on the windscreen and ob-
scure your view of the road.
● Always note the corresponding warnings on ⇒ page 227.
CAUTION
In icy conditions, always check that the wiper blades are not frozen to the
glass before using the wipers for the first time. If you switch on the wipers
when the wiper blades are frozen to the windscreen, you could damage
both the wiper blades and the wiper motor.
Note
● The windscreen wipers will only work when the ignition is switched on.
● In certain versions of vehicles with alarms, the windscreen wiper will on-
ly work when the ignition is on and the bonnet closed.
● When in use, the wipers do not go as far as the rest position. When the
lever is moved to the 0 position, they move to the rest position.
● The next speed down will automatically be selected if wiper speed 2
⇒ fig. 81 or 3 is selected when the vehicle stops. The set speed will be re-
sumed when the vehicle starts again
● The windscreen will be wiped again after approximately five seconds
once the “automatic wipe/wash system” has been operated, provided the
vehicle is in transit (drip function). If you activate the wipers less than three
seconds after the drip function, a new wash sequence will begin without the
last wipe. For the “drip” function to work again, you have to turn the ignition
off and then on again. 

218Checking and refilling levels
WARNING (Continued)
● Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!
● Do not unscrew the cap on the expansion tank when the engine is
hot. If the coolant is hot, the cooling system will be pressurised!
● Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.
● Always make sure you have not left any objects, such as cleaning
cloths and tools, in the engine compartment.
● If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
● If any work has to be performed when the engine is started or with
the engine running, there is an additional, potentially fatal, safety risk
from the rotating parts, such as the drive belts, alternator, radiator fan,
etc., and from the high-voltage ignition system. You should also observe
the following points:
–Never touch the electrical wiring of the ignition system.
– Ensure that jewellery, loose clothing and long hair do not get trap-
ped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
– Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is ap-
plied. Danger of death.
● If work has to be carried out on the fuel system or on electrical com-
ponents, you must observe the following safety notes in addition to the
above warnings:
–Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
– Do not smoke.WARNING (Continued)
– Never work near naked flames.
– Always have a fire extinguisher on hand.
CAUTION
When topping up service fluids, make sure not to mistake them. Using the
wrong fluids could cause serious malfunctions and engine damage!
For the sake of the environment
Service fluids leaks are harmful to the environment. For this reason you
should make regular checks on the ground underneath your vehicle. If you
find spots of oil or other fluids, have your vehicle inspected in a specialised
workshop. 

231
Checking and refilling levels
WARNING (Continued)
● Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alarm will otherwise be triggered.
● When disconnecting the battery from the vehicle electrical system,
disconnect first the negative cable and then the positive cable.
● Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never re-
verse the polarity of the connections. This could cause an electrical fire.
● Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery which
has frozen. A flat battery can freeze at temperatures around 0°C.
● Ensure that the vent hose is always connected to the battery.
● Never use a defective battery. This could cause an explosion. Replace
a damaged battery immediately.
CAUTION
● Never disconnect the battery if the ignition is switched on or if the en-
gine is running. This could damage the electrical system or electronic com-
ponents.
● Do not expose the battery to direct sunlight over a long period of time,
as the intense ultraviolet radiation can damage the battery housing.
● If the vehicle is left standing in cold conditions for a long period, protect
the battery from freezing. If it freezes it will be damaged. Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries.
– Open the engine bonnet and the battery cover ⇒ 
in Safety in-
structions on working in the engine compartment on page 217
⇒ 
in Warnings on handling the battery on page 230.
– Check the colour display in the "magic eye" on the top of the
battery.
– If there are air bubbles in the window, tap the window gently
until they disperse.
The position of the battery is shown in the corresponding engine compart-
ment diagram ⇒ page 273.
The “magic eye” indicator, located on the top of the battery changes colour,
depending on the charge state and electrolyte level of the battery.
There are two different colours:
● Black: correct charge status.
● Transparent/clear yellow: the battery must be replaced. Contact a spe-
cialist workshop. 
