Driving and operating131
Do not accelerate while engaging a
gear. Never depress the accelerator
pedal and brake pedal at the same
time.
When a gear is engaged, the vehicle
slowly begins to creep when the
brake is released.
Gears 3, 2, 13, 2, 1=Transmission does not
shift above the selected
gear.
Press button on selector lever to
engage 3 or 1.
Only select 3, 2 or 1 to prevent
automatic upshifting or as an aid in
engine braking.
Engine braking
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 or snow. Move the selector
lever between D and R in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking
Apply the parking brake and engage P .
The ignition key can only be removed
when the selector lever is in position
P .Manual mode
Move selector lever out of position D
towards the left and then forwards or backwards.
+=Shift to a higher gear.-=Shift to a lower gear.
If a higher gear is selected when
vehicle speed is too low, or a lower
gear when vehicle speed is too high,
the shift is not executed.
If engine speed is too low, the
transmission automatically shifts to a
lower gear above a specific vehicle
speed.
138Driving and operating
If F appears in the transmission
display, continued driving is not
possible.
Have the cause of the fault remedied
by a workshop.
Interruption of power
supply
The clutch is not disengaged if there
is an interruption of the power supply
when a gear is engaged. The vehicle
cannot move.
If the battery is discharged, start the
vehicle using jump leads 3 186.
If the cause of the fault is not a
discharged battery, seek the
assistance of a workshop.
If the vehicle must be moved out of the flow of traffic, disengage the
clutch as follows:
1. Apply parking brake and switch off
ignition.
2. Open the bonnet 3 154.
3. Clean the transmission around the cap so that no dirt can get intothe opening when the cap is
removed.
4. Rotate cap to slacken and remove
by lifting upwards.
5. Using a flat-head screwdriver, turn the adjusting screw under the
cap clockwise until clear
resistance can be felt. The clutch
has now been disengaged.
6. Refit cleaned cap. The cap must be in full contact with the housing.Caution
Do not turn beyond the resistancesince this could damage the
transmission.
Caution
Towing the vehicle and starting
the engine is not permitted when
the clutch has been disengaged in this way, although the vehicle can
be moved a short distance.
Seek the immediate assistance of a
workshop.
Driving and operating139Brakes
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 you depress the
brake pedal firmly. You need to use
considerably more force 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 89.
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 though 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.
Control indicator u 3 89.
Adaptive brake lamp During full braking, all three brake
lamps flash for the duration of ABS
control.Fault9 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.
Have the cause of the fault remedied
by a workshop.
144Driving and operating
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles. It
is the driver, however, who bears full
responsibility for parking.
The system consists of four ultrasonic parking sensors in each of the front
and rear bumpers.
Control indicator r 3 90.
Notice
Attached parts in the detection area
cause system malfunction.
ActivationWhen reverse gear is engaged, the
system switches itself on
automatically.
The system can also be activated at
low speed by pressing the r button.
An obstacle is indicated by buzzers.
The interval between the buzzers
becomes shorter as the vehicle gets closer to the obstacle. When the
distance is less than 30 cm, the buzzer is continuous.9 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.
Deactivation
Deactivate the system by pressing
the r button.
The system automatically switches itself off when the vehicle is driven above a certain speed.
Towing equipment
The system automatically detects
factory-fitted towing equipment.
The rear parking sensors are
deactivated when towing.
Driving and operating147
For the values specific to your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
General information The official fuel consumption and
specific CO 2 emission figures quoted
relate to the EU base model with
standard equipment.
Fuel consumption data and CO 2
emission data are determined
according to regulation
R (EC) No. 715/2007 (in the latest
applicable version), taking into
consideration the vehicle weight in
running order, as specified by the
regulation.
The figures are provided only for the
purpose of comparison between
different vehicle variants and must
not be taken as a guarantee for the
actual fuel consumption of a
particular vehicle. Additional
equipment may result in slightly
higher results than the stated
consumption and CO 2 figures.Furthermore, fuel consumption is
dependent on personal driving style
as well as road and traffic conditions.
Natural gas
The fuel consumption information
was obtained using reference fuel
G20 (methane proportion
99 - 100 mol%) under prescribed
driving conditions. When using
natural gas with a lower proportion of
methane, the fuel consumption can
differ from the specified values.Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case, use the coupling ball
bar for towing. Always keep the
coupling ball bar in the vehicle.
Installation dimensions of factory-
fitted towing equipment 3 208.
Driving characteristics and towing tips Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the
coupling ball, is being used to reduce snaking movements.
148Driving and operating
For trailers with low driving stability
and trailers with a permitted gross
vehicle weight of more than 1300 kg a speed of 80 km/h must not be
exceeded; the use of a stabiliser is
recommended.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 206.
Trailer towing Trailer loads
The permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be
exceeded. The actual trailer load is
the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to max. 12 %
The permitted trailer load applies up to the specified incline and up to an
altitude of 1000 metres above sea
level. Since engine power decreases
as altitude increases due to the air becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10 %
for every 1000 metres of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than 8 %, e. g. motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 198.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.The maximum permissible vertical
coupling load (75 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum load,
especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.
Rear axle load When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by 90 kg and the gross vehicle weight
rating by 75 kg. If the permissible rear
axle load is exceeded, a maximum
speed of 100 km/h applies.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.

Fitting the coupling ball bar From underneath at the recesses,
pull the cover in the bumper
rearwards at a slight angle.
Disengage and fold down the socket. Remove the sealing plug from the
opening for the coupling ball bar and
stow it.
Checking the tensioning of the
coupling ball bar
■ Red marking on rotary knob must
point towards white marking on
coupling ball bar.
■ The gap between the rotary knob and the coupling ball bar must beapprox. 6 millimetres.
■ Key must be at position c ( 1).
Otherwise, the coupling ball bar must be tensioned before being inserted:
■ Unlock coupling ball bar by turning key to position c ( 1)
150Driving and operating
■ Pull out rotary knob and turnclockwise as far as it will go.
Inserting the coupling ball bar
Insert the tensioned coupling ball bar
in the opening and push firmly
upwards until it audibly engages.
The rotary handle snaps back into its
original position resting against the
coupling ball bar without a gap.9 Warning
Do not touch rotary handle during
insertion.
Lock the coupling ball bar by turning
the key to position e ( 2). Remove the
key and close the protective flap.
Eye for break-away stopping cable
Attach breakaway stopping cable to
eye.
Check that the coupling ball bar is
correctly installed
■ Green marking on rotary knob must
point towards white marking on
coupling ball bar.
■ There must be no gap between the
rotary handle and the coupling ball
bar.
■ The coupling ball bar must be firmly
engaged in the opening.
■ The coupling ball bar must be locked and the key removed.9 Warning
Towing a trailer is permitted only
when a coupling ball bar is fitted correctly. If the coupling ball bardoes not engage correctly, seekthe assistance of a workshop.
