160Driving and operatingEngine exhaust9Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Exhaust filter
Automatic cleaning process
The exhaust filter system filters soot particles out of the exhaust gases.
The start of saturation of the exhaust
filter is indicated by the temporary
illumination of + or C ,
accompanied by a message in the
Driver Information Centre and a
chime.
As soon as the traffic conditions
permit, regenerate the filter by driving at a vehicle speed of at least 40 mph
until the control indicator
extinguishes.
Notice
On a new vehicle, the first exhaust
filter regeneration operations may
be accompanied by a burning smell,
which is normal. Following
prolonged operation of the vehicle at very low speed or at idle, water
vapour can be emitted at the
exhaust on acceleration. This does
not affect the behaviour of the
vehicle or the environment.
Cleaning process not possible
If + or C stays on, accompanied
by an audible signal and a message,
this indicates that the exhaust filter
additive level is too low.
The reservoir must be topped-up
without delay. Seek the assistance of
a workshop.Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on page 3 268 could damage the
catalytic converter or electronic
components.
Unburnt petrol will overheat and damage the catalytic converter.
Therefore avoid excessive use of
the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.

Do not leave the vehicle while it is
being held at a stop by adaptive
cruise control. Always move
selector lever to park position P
and switch off the ignition before
leaving the vehicle.
Setting the following distance
When adaptive cruise control detects
a slower moving vehicle in the driving path, it will adjust the vehicle speed tomaintain the following distance
selected by the driver.
The following distance can be set to
close (1 bar), normal (2 bars) or far
(3 bars).
If the engine is running and the
adaptive cruise control is enabled
(grey), you can modify the following
distance setting:
Press GAP, the current setting is
shown in the Driver Information
Centre.
Press GAP again to change the
following distance: The new setting is
displayed in the Driver Information
Centre.
The selected following distance is
indicated by full bars in the adaptive
cruise control page.9 Warning
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
Following distance must be
adjusted or the system switched
off when required by the prevailing
conditions.
Detecting the vehicle ahead
If the system does not detect a vehicle
in the driving path, U is displayed
in the Driver Information Centre. The system operates as conventional
cruise control.
If the system detects a vehicle in the
driving path, V is displayed in the
Driver Information Centre. The
system operates as conventional
cruise control.
If the system detects a vehicle in the
driving path which is too close or too
slow, it adjusts the speed accordingly. X is displayed in the Driver
Information Centre.
If the system reaches the limit of
adjusting the speed and the driver
does not react to this situation, the
system is automatically deactivated
and W is displayed in the Driver
Information Centre.
If the set speed is temporarily
exceeded by the driver, the system is automatically deactivated and Z is
displayed in the Driver Information Centre.
