Engine exhaust Diesel particle filter 3
The diesel particle filter system filters
harmful soot particles out of the exhaust
gases. The system includes a self-cleaning
function that run automatically during
driving. The filter is cleaned by burning off
the soot particles at hi gh temperature. This
process takes place automatically under
set driving conditions and may take up
to 25 minutes. Fuel consumption may be
higher during this period. The emission of
smells and smoke during this process is
normal.
Picture no: 18544s.tif
Under certain driving conditions, e.g. short
journeys, the system may not clean itself
automatically.
If the filter requires cleaning and previous
driving conditions did not enable
automatic cleaning, control indicator !
flashes. Continue driving, keeping engine
speed above 2000 rpm
-1. Shift down if
necessary. Diesel partic le filter cleaning is
then initiated.

Warning
Engine exhaust gases contain poisonous
carbon monoxide, which is colourless
and odourless and could be fatal if
inhaled.
If exhaust gases penetrate the vehicle,
open windows and contact a workshop
for assistance.
Avoid driving with the tailgate open,
since exhaust gas can enter the interior
of the vehicle.

Drive Control Systems Electronic Stability Program
(ESP
®Plus
) 3
ESP®
Plus
improves driving stability when
necessary in any driving situation
regardless of the type of road surface or
tyre grip. It also prevents the drive wheels
from spinning.
As soon as the vehicle starts to swerve
(understeer/oversteer), engine output is
reduced and the wheels are braked
individually. This considerably improves
the driving stability of the vehicle on
slippery road surfaces.
ESP®
Plus
is ready for operation as soon as
the ignition is switched on and control
indicator v goes out.
When the ESP®
Plus
comes into action,
v flashes. The vehicle is now in
a critical situation;
ESP®
Plus
allows you to keep control of the
vehicle and reminds you to match your
speed to the road conditions.
Picture no: 18252s.tif
Control indicator
v
The warning lamp lights up for a few
seconds when the ignition is switched on.
The system is now ready for operation.
Flashing during driving:
This shows the system has come into
action. The engine output may be reduced
(the sound of the engine changes) and the
vehicle may be braked automatically to a
small degree.
Illuminates while driving:
The system is switched off 3 or a fault is
present. Continued driving is possible.
However, directional control may
deteriorate depending on the road surface
conditions.
Switch on ESP®
Plus
again and have cause
of fault remedied by a workshop. The self-
diagnosis that is integrated in the system
will help you to find a solution quickly.

Warning
Do not let this special safety feature
tempt you into taking risks when driving.
ESP®
Plus
does not negate the laws of
physics.

For safety reasons the cruise control
system cannot be activated until the foot
brake has been operated, otherwise the
control indicator flashes m.
Cruise control is operated with switch m, g,
and button 0 on the turn signal stalk.
Do not use the cruise control if it is not
advisable to maintain a constant speed
(e.g. in situations presenting a danger to
yourself and other road users, in heavy
traffic or on winding, slippery or greasy
roads). With automatic transmission
3, engage
cruise control only in D, or with manual
transmission automated 3 in automatic
mode only.

Ultrasonic parking sensors 3
Park pilot makes reverse parking easier by
measuring the distance between the back
of the vehicle and obstacles to the rear. It is
the driver, however, who maintains full
responsibility for parking.
The system records the distance using four
sensors in the rear bumper.
Picture no: 18254s.tif
To activateThe park pilot system activates
automatically when the ignition is switched
on and reverse gear is engaged.
Its operational readin ess is indicated by
illumination of the LED in the button r 3. If the vehicle approaches an obstacle, a
series of acoustic signals sound. The
interval between the signals becomes
shorter as the vehicle gets closer to the
obstacle. When the distance is less
than 30 cm, the signal is continuous.
9
Warning
Under certain circum
stances, various
reflective surfaces on objects or clothing
as well as external noise sources may
cause the system to fail to detect obsta-
cles.

Deflation detection system (DDS)3
The deflation detection system monitors
the revolutions of all four vehicles from a
speed of approximately 30 km/h. If there is
a loss of pressure in one of the tyres, its
diameter is reduced, and therefore also the
wheel rotation speed. Warning lamp w
lights red.
Stop immediately and check tyre pressure.
Fit the spare wheel if necessary 3 196,
3 200. Control indicator
w
If control indicator w lights up red while
driving, there is a loss of pressure. Stop
immediately and check tyre pressures. A
maximum speed of 80 km/h is permitted
for tyres run flat 3 3 171.
Control indicator illumination w in yellow
indicates a fault in the system. Have cause
of fault remedied by a workshop. The
system’s integrated se lf diagnostics allow
faults to be quickly remedied.
The control indicator flashes three times
when the system is initialising.
Tyre pressure 3169, 3264.
Picture no: 18245s.tif
System initialisationAfter correcting the tyre pressure or
changing a tyre/wheel, the system must be
initialised: turn the ignition on, press the
DDS button for approx. 4 seconds. Control
indicator w flashes three times. The system
is operational after driving a certain
distance.
Only initialise the system if all tyres have
the prescribed pressure.
9
Warning
The deflation detection system does not
replace manual checks with a suitable
gauge.
Check tyre pressures at least every
14 days and prior to any long journey;
the tyres should be checked when cold.
Don’t forget to check the spare 3.

Hydraulic brake system The foot brake comprises two independent
brake circuits.
If a brake circuit fails, the vehicle can still be
braked using the other brake circuit.
However, the brake pedal must be
depressed a considerable way before any
braking effect occurs, and much more
force is required. The braking distance is
longer. Contact a workshop for assistance
before continuing to drive. To ensure that full
pedal travel can be
utilised, especially in case of a fault in one
of the brake circuits, there must be no mats
in the vicinity of the pedals 3150.
When the engine is not running, the
support of the brake servo unit disappears
once the brake pedal has been depressed
once or twice. Braking effect is not
reduced, but braking requires significantly
greater force. This is especially important
to bear in mind when towing.
The brake fluid level should be checked
regularly. If the brake fluid level is too low
and the hand brake is not applied, control
indicator R on the instrument panel
illuminates 389.
Picture no: 18257s.tif
Brake system control indicator R
The control indicator lights up when the
ignition is switched on when the hand
brake is applied or when the brake or
clutch fluid level is too low. Brake fluid
level 3246.
For vehicles with manual transmission
automated 3, the control indicator flashes
for a few seconds when the ignition is
turned off when the hand brake is not
applied.
9
Warning
If the control indicator illuminates when
the hand brake is released, stop driving
immediately. Contact a workshop for
assistance.
Back to overview

166 Driving and operationAnti-lock brake system (ABS
u)
ABS prevents the wheels from locking.
ABS starts to regulate brake pressure as
soon as a wheel shows a tendency to lock.
The vehicle remains steerable, even during
hard braking.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that the
pedal is pulsating. Do not reduce the
pressure on the pedal.
Picture no: 18258s.tif
Control indicator u for ABS
It illuminates for a few seconds when
ignition is switched on. Once the control
indicator goes out, the system is ready for
operation.
If the control indica tor does not go out
after a few seconds, or if it illuminates while
driving, there is a fault in the ABS. The
brake system remains operational without
ABS regulation.
Adaptive brake lamp 3
During full-on braking, all three brake
lamps flash for the duration of ABS control. Self testing
When the engine is started and the vehicle
starts off, the system performs a self-check,
which may be audible.
Fault
Have cause of fault remedied by a
workshop. The system’s integrated self
diagnostics allow faults to be quickly
remedied.
9
Warning
If there is a fault in the ABS, the wheels
may be liable to lock due to braking that
is heavier than normal. The advantages
of ABS are no longer available. During
hard braking, the vehicle can no longer
be steered and may swerve.
