ulate filter
, emission control system fault
 and glow plugs
D), take
the vehicle to a specialised workshop to repair the fault.
WARNING
•Always drive according to the road weather conditions, the terrain and
traffic. Driving recommendations should never lead to illegal manoeuvres
in surrounding traffic.•The diesel engine particulate filter may reach extremely high tempera-
tures; it should not enter into contact with flammable materials under-
neath the vehicle. Otherwise there is a risk of fire.

Unlocking and locking
108Up to eight remote control keys can be used.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
vehicle. The system is then primed.
When does the system trigger an alarm?
The system triggers an alarm if the following unauthorised actions are carried
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 seconds.
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 deactivates
the anti-theft alarm system. If you do not switch on the ignition within 15
seconds, the alarm is triggered.
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.

quickly.1. Use a soft cloth to remove dust and dirt from the rubber seals.
2. Apply a specialist care product to the rubber seals.
The rubber strips on the doors, windows, bonnet and tailgate will remain
pliable and last longer if they are treated with a suitable care product (for
example silicone spray).
Caring for rubber seals will also prevent premature ageing and leaks. The
doors will be easier to open. If rubber seals are well looked after, they will not
freeze so quickly in winter.Door lock cylinders
The door lock cylinders can freeze up in winter.To de-ice the lock cylinders you should only use spray with lubricating and
anti-corrosive properties.Cleaning chrome parts1. Clean chrome parts with a damp cloth.
2. Polish chrome parts with a soft, dry cloth.If this does not provide satisfying results, use a specialist chrome cleaning
product . Chrome cleaning products will remove stains from the surface.

Cleaning the engine compartment
Take special care when cleaning the engine compartment.Anti-corrosion treatment
The engine compartment and the surface of the power unit are given anti-
corrosion treatment at the factory.
Good corrosion protection is particularly important in winter when the vehicle
is frequently driven on salted roads. To prevent the salt corroding the vehicle,
the entire engine compartment should be thoroughly cleaned before and
after winter.
Yo u r A u t h o r i s e d S e r v i ce Ce n t re has got the necessary equipment to provide
the correct cleaning and preserving products. For this reason, we recommend
having this work performed by them.
The anti-corrosion protection is usually removed if the engine compartment
is cleaned with grease removing solutions, or if you have the engine cleaned.
On commissioning this work, ensure that all surfaces, seams, joints and
components in the engine compartment are given anti-corrosion treatment.
WARNING
•When working in the engine compartment, always observe the safety
warnings ⇒page 221.•Before opening the bonnet, switch the engine off, apply the handbrake
firmly and always remove the key from the ignition.•Allow the engine to cool before you clean the engine compartment.•Do not clean the vehicle underbody, wheel arches or wheel trims
without protecting your hands and arms. You may cut yourself on sharp-
edged metal parts. Failure to comply could result in injury.•Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident. Directly after washing, avoid sudden and sharp braking.
•Never touch the radiator fan. It is temperature-controlled and could
start automatically, even when the key is removed from the ignition!For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed.
The polluted water must be cleaned in an oil separator. For this reason,
engine washing should only be carried out at a specialised workshop or an
adequate petrol station.Vehicle interior maintenancePlastic parts and dash panel cleaning– Use a clean, damp cloth to clean plastic parts and the dash panel.
– If this does not provide satisfactory results, use a special solvent-free plastic cleaning product.
WARNING
Never clean the dash panel and the airbag module surface with cleaners
containing solvents. Solvents cause the surface to become porous. If the
airbag triggered, plastic parts could become detached and cause injuries.

Filter pre-heater
Your vehicle is fitted with a fuel filter glow plug system, making it well
equipped for operation in winter. This ensures that the fuel system remains
operational to approx. -24 °C, provided you use winter diesel which is safe to
-15 °C.
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24 °C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (thinners or similar products) with diesel fuel.Working in the engine compartmentSafety instructions on workin
g in the engine compartment
