lay and have the fault rectified.
Diesel particulate filter
Applies to: vehicles with diesel particulate filter

|
Particulate filter: system fault. See owner's
manual
The diesel particulate filter requires regenera­

tion.
You can assist the self-cleaning function of
the filter by driving as follows:
Drive at a speed of at least 60 km/h for about
15 minutes in 4th or 5th gear (on vehicles with
manual gearbox), or with the selector lever in po­
sition S (on vehicles with automatic gearbox).
Keep the engine speed at about 2000
rpm.
As a
result of the increase in temperature, the soot in
the filter will be burned off. The indicator lamp
will go out once the cleaning process has been
completed successfully.
If the indicator lamp does not go out, drive to a
qualified workshop without delay and have the
fault rectified.
A WARNING
It is essential that you adjust your speed to
suit the weather,
road,
terrain and traffic
con­

ditions. The recommended driving speed
must never lead to the driver disregarding the
traffic regulations.

(T) Note

For more information about the diesel partic­
ulate filter, refer to

your
foot off the accel­
erator.
If the rev limiter has been activated because of a
fault in the engine management system, the in­
dicator lamp
Q or[|2g
will also light up. Make
sure that the engine speed does not exceed the
speed displayed in the driver information system,
for example when shifting down a gear. Drive to
a qualified workshop without delay and have the
fault rectified.

Central locking system
Accidental lock-out
To
prevent
yourseLf from being locked out, only
lock the vehicle when the remote control key is
not in the vehicle and all of the doors and the

A WARNING
- Always take the key with you when leaving
the vehicle - even if
you

gone for a short time. This is especially im­
portant if children are left in the car. They
might otherwise be able to start the engine
or use power-operated equipment such as
the electric windows - this could lead to in­

juries.

- Locked doors could delay assistance in an
emergency, potentially putting lives at risk.
Do not leave anyone (especially children) in
the vehicle.
© Note
- Never leave any valuable items in the
vehi­

cle unattended. Even a locked vehicle is not
a safe.
- When you lock the vehicle, the LED on the
driver's window sill flashes. If the LED is
still on about 30 seconds after the vehicle is

locked,
the central locking system is not
working properly. You should have the
mal­

function repaired by
a
qualified workshop.
