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.

A WARNING
- Never run the engine in confined spaces.
The exhaust gases are toxic - risk of poison­

ing!

- Never remove the key from the ignition
while the vehicle is moving. The steering
lock would engage, and you would not be
able to steer the car - risk of accident!
© CAUTION
Avoid high engine speeds, full throttle and ex­
treme load conditions until the engine has
reached its normal operating temperature;
otherwise this can damage the engine.
© For the sake of the environmen
Do not warm up the engine by running it with
the car stationary. You should drive off imme­
diately whenever possible. This will help avoid
unnecessary exhaust emissions.
© Note
- If it is difficult to turn the ignition key to po­
sition ®, move the steering wheel (to take
the load off the steering lock mechanism)
until the key turns freely.
- Any noises which may be heard when the
engine is started are quite normal and no
cause for concern.

steering lock engage.
The steering lock acts as a theft deterrent.

A,
WARNING
- Never switch off the engine until the vehicle
is stationary. Otherwise you may not have
the full benefit of the brake servo and pow­
er steering. You may need more strength to
steer and brake the vehicle than you nor­
mally would. This would mean a greater risk
of accidents and serious injury, because you
cannot steer and brake in the normal
man­

ner.
- Never remove the key from the ignition
while the vehicle is moving. The steering
lock could engage suddenly, and you would
not be able to steer the car.
- Always take the key with you when you leave
the vehicle. Otherwise the engine can be
started or power-operated equipment such
as the electric windows can be used. This
could result in serious injury.
- When parking, always move the selector
lever to position
P
to prevent the vehicle
from rolling back accidentally.
© CAUTION
If the engine has been working hard
fora
long

time,
there is a risk of heat building up in the
engine compartment after the engine has
been switched off; this could cause engine
damage. For this reason, you should Leave the
engine idling for about 2 minutes before
switching
it
off.

Note
After the engine is stopped, the radiator fan
may remain on or turn itself back on for up to
10 minutes, even if the ignition is switched
off. This may occur for the following reasons:
- Residual heat has raised the coolant
tem­

perature.
- Direct sunlight has additionally heated up
the engine compartment while the engine is

warm.

- Applies to vehicles with diesel particulate
filter: The emission control system is hot
because of the regeneration process, even
though the engine has
not
yet reached oper­
ating temperature.

WARNING
You should switch on the off-road mode or
switch off the ESC/traction control system
(ASR) only if your driving ability and the traf­
fic conditions allow you to do so safely -
dan­

ger of skidding!
- The stabilising function is restricted when
off-road mode is switched on. The driven
wheels may start to
spin,
causing the
vehi­

cle to lose grip, in particular on slippery or
wet roads.
- When the ESC/traction control system
(ASR) is switched off, the vehicle will not be

stabilised.

Brakes
New brake pads
New brake pads do not give full braking effect for
the first 400 km, they must first be "bedded in".
However, you can compensate for the slightly re­
duced braking effect by applying more pressure
on the brake pedal. Avoid placing a heavy load on
the brakes during the running-in period.
Wear
The rate of wear on the brake pads depends a
great deal on how you drive and the conditions in
which the vehicLe is operated. Negative factors

are,
for instance, city traffic, frequent short trips
or hard driving with abrupt starts and stops.
Noises
Brake noise may develop in certain situations, de­
pending on the speed, braking force and ambient
conditions (such as temperature and relative hu­
midity).
Effect of moisture and salt
In certain conditions, such as in heavy
rain,
early
morning dew, or after washing the car or driving
through water, the full braking effect can be de­
layed by moisture (or in winter by ice) on the
discs and brake pads. The brakes should be
< "dried" by pressing the pedal to restore full brak-

R
ing effect.
When you are driving at higher speeds with the
windscreen wipers on, the brake pads are very
briefly brought into contact with the brake discs.
This automatic process which goes unnoticed by
the driver is carried out at regular intervals and is
intended to improve braking response in wet
con­

ditions.
The effectiveness of the brakes can also be
tem­

porarily reduced if the car is driven for some dis­
tance without using the brakes when there is a
lot of salt on the road in winter. The layer of salt
that accumulates on the discs and pads can be
removed with a few cautious brake applications.
Corrosion
There may be a tendency for dirt to build up on
the brake pads and corrosion to form on the discs
if the car is used infrequently, or if
you
only drive
low mileages without using the brakes very

much.

If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed
•=> A-

Faults in the brake system
If the brake pedal travel should ever increase
suddenly, this may mean that one of the two
brake circuits has failed. Drive immediately to the
nearest qualified workshop and have the fault

rectified.
On the way to the dealer, be prepared
to use more pressure on the brake pedal and al­
low for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid level
is monitored electronically.
Brake servo
The brake servo amplifies the pressure you apply
to the brake pedal. It only works when the engine
is running. •

Jump-starting
Before starting the engine
If
necessary,
the engine can be started by con­
necting it to the battery of another vehicle.
If the engine fails to start because of
a
dis­
charged battery, the vehicle battery can be
con­

nected to the battery of another vehicle to start
the engine. Suitable jump leads are required.
Both vehicle batteries must be rated at 12 V. The
capacity (Ah) of the booster battery should not
be significantly lower than that of the discharged
battery.
Jump leads
The jump Leads must be heavy enough to carry
the starter current. Refer to the details given by
the manufacturer.
Only
use
jump leads with insulated battery
clamps.
Positive cable - usually red.
Negative cable - usually black.
WARNING
- When it is discharged the vehicle battery
can freeze at temperatures around 0°C. A
frozen vehicle battery must first be thawed
out before connecting the jump leads - risk
of explosion and chemical burns! After
jump-starting the vehicle, drive to a quali­
fied workshop without delay and have the
vehicle battery checked.
- The engine compartment is a potentially
hazardous area and working here can lead
to serious injuries. Before carrying out any
work in the engine compartment please
read and observe the warnings
*page
295.
- Incorrect handling of the jump leads may
result in the vehicLe battery exploding (risk
of serious injury). Please observe the follow­
ing rules to minimise the risk of injury:
- The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive terminal
must not touch metal parts of the vehicle:
this can cause short circuiting.
- Position the jump leads in such a way that
they cannot come into contact with any
moving parts in the engine compartment.
- Do not lean over the vehicle battery - risk of
chemical burns!
- The screw plugs on the battery cells must be
screwed in firmly.
