The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up. The quality
of the passenger compartment air
deteriorates, which may cause the vehicle occupants to feel drowsy.
In warm and very humid ambient air
conditions, the windscreen may mist
up from outside, when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate V.

Control of the vehicle
Never coast with engine not
running (except during Autostop)
Many systems will not function in this
situation (e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there will be a controlled reduction in power steering assist and vehicle
speed is reduced.
Stop-start system 3 113.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Steering
If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.
Driving and operating115Restarting the engineManual transmission
The selector lever must be in neutral to enable an automatic restart.
Depress the clutch pedal to restart the
engine.
Manual transmission automated
If the lever is in position N, select
another gear, otherwise release the brake pedal or move the lever to +, –
or R to enable an automatic restart.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart may be noticeable.
Restarting the engine with the key When one of the following conditions
occurs during an Autostop, the
engine will need to be restarted
manually using the key.
● the driver's seat belt is unfastened and the driver's door
is opened
● three minutes have elapsed since the engine was switched offIn this event, control indicator ^
flashes in the Driver Information
Centre in conjunction with a warning
chime. Depending on version, a
corresponding message may also be
displayed in the Driver Information
Centre 3 88.
Fault
If control indicator Æ illuminates in the
instrument cluster, there is a fault in
the stop-start system 3 87.
Depending on version, 9 will
illuminate as an alternative if control
indicator Æ is not present. A
corresponding warning message,
e.g. Start&Stop unavailable , may also
be displayed in the Driver Information
Centre 3 88.
Generic warning 9 3 79.
Seek the assistance of a workshop.Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply parking brake without pressing release
button. Apply as firmly as
possible on a downhill slope or
uphill slope. Depress brake
pedal at the same time to
reduce operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear before switching off
the ignition. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear
before switching off the ignition. Turn the front wheels towardsthe kerb.
Driving and operating117Control indicator % illuminates when
diesel particle filter is full. Start
cleaning process as soon as possible
to avoid damage to the engine.
Cleaning process To activate cleaning process,
continue driving, keep engine speed
above 2000 rpm. Shift down if
necessary. Diesel particle filter
cleaning is then started.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
Control indicator % extinguishes as
soon as the self-cleaning operation is
complete.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on pages 3 130, 3 178 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.
Manual transmission
To engage reverse, with the vehicle
stationary, wait three seconds after
depressing the clutch pedal, pull up
the collar on the selector lever and
engage the gear.
If the gear does not engage, set the
lever to neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch
pedal completely. Do not use the
pedal as a foot rest.
Driving and operating119Selector lever
Always move the selector lever in the
appropriate direction as far as it will
go.
Notice
Do not hold the selector lever in an
intermediate position. Not fully
engaging a gear may lead to
malfunction and a warning message may be displayed in the Driver
Information Centre.
Return the selector lever to the
centre position. After a short while,
N will be displayed in the Driver
Information Centre and the system
will operate normally again.
Driver Information Centre 3 88.
After selecting A/M, + or - and
releasing the selector lever, the lever automatically returns to the centre
position.N:neutralo:drive positionA/M:switch between automatic and

It is not advisable to drive with the hand resting on the selector lever.
Starting-off
When the engine is started, depress
the brake pedal and move the
selector lever towards + to engage
first gear. Shift to a higher or lower
gear by moving selector lever to + or -.
Gears can be skipped by moving the selector lever repeatedly at short
intervals.
The driver will be alerted to an
incorrect gear selection by an audible warning chime in conjunction with a
message in the Driver Information
Centre 3 88. The system will
downshift, selecting the most
appropriate gear automatically.
If R is selected, reverse gear is
engaged. The vehicle starts to move
when the brake pedal is released. To
start off quickly, release the brake
pedal and accelerate immediately
after engaging a gear.
120Driving and operatingMove the selector lever towards A/M
to engage automatic mode; the
transmission shifts to other gears automatically, dependent on drivingconditions.
To engage manual mode, move the
selector lever towards A/M. The
current gear will appear in the
transmission display.
Stopping the vehicle
In automatic or manual mode,
first gear is engaged and the clutch is
released when the vehicle is stopped.
In R, reverse gear remains engaged.
When the vehicle is at a standstill, if
the engine is running and a forward or reverse gear is engaged, a warning
chime will sound and the
transmission automatically shifts to
N in certain situations.
When stopping on gradients, engage
parking brake or depress the brake pedal. To prevent overheating of theclutch, an intermittent audible
warning chime may sound as a signal
to depress the brake pedal or apply
the parking brake.Switch off engine if stopping for a
lengthy period, e.g. in traffic jams.
Engine braking
Automatic mode
When driving downhill, the manual transmission automated does not shift into higher gears until a fairly
high engine speed has been reached. It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect,
select a lower gear in good time when
driving downhill.
Rocking the vehicle Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud, snow or a hole. Move the
selector lever between R and A/M (or
between + and -) in a repeat pattern,
while applying light pressure to the
accelerator pedal. Do not race the
engine and avoid sudden
acceleration.Parking
Apply the parking brake. The most
recently engaged gear (see
transmission display) remains
engaged.Caution
Do not leave the vehicle with the
transmission in position N.
When the ignition is switched on, a
warning chime will sound when the
vehicle is parked if the transmission is still in N.
When the ignition is switched off, the transmission no longer responds to
movement of the selector lever.
Manual mode If engine speed is too low, the
transmission automatically shifts to a
lower gear.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions. If engine
122Driving and operatingmessage may appear in the Driver
Information Centre in conjunction with
a warning chime 3 93.
Notice
The volume of the warning chime
can also be adjusted via the Driver
Information Centre 3 88.
Have the cause of the fault remedied by a workshop.Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek the assistance of a workshop before
continuing your journey.
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. It is especially important to bear this in mind when being towed.
Control indicator R 3 82.
Antilock brake system
Antilock brake system (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.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
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.
After starting off the system performs a self-test which may be audible.
Fault
In the event of a fault, control indicator u illuminates in the instrument
cluster. Depending on version, a
corresponding warning message,
e.g. ABS unavailable , may also be
displayed in the Driver Information
Centre 3 88.
Driving and operating129● The bumper is damaged. Takethe vehicle to a workshop to
repair the system.
● Other conditions, such as vibrations from a jackhammer,
are affecting system
performance.
In the event the system still does not
work properly, seek the assistance of
a workshop.
A warning chime is also sounded
briefly if a fault is present when
reverse gear is engaged 3 93.
Notice
The volume of the warning chime
can also be adjusted via the Driver
Information Centre 3 88.
Important hints for using the
parking assist systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention has to be paid to
low obstacles which can damage
the lower part of the bumper. If
such obstacles leave the detection area of the sensors during
approach of the vehicle, a
continuous warning tone will
sound.Caution
Performance of the sensor can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
systems can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles involved (e.g.
off-road vehicles, mini vans,
vans). Object identification in the upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross section, like objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist will not avoid a
collision with objects which are out
of the detection range of the
sensors.
Notice
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
The sensor may detect a non-
existent object (echo disturbance)
caused by external acoustic or
mechanical disturbances.
