or is shown as a symbol in the Driver Information Centre.
Control indicator - 3 89.
Restart of the engine by the
stop-start system The selector lever has to be in neutral
to enable an automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically by the stop-start system:
■ The stop-start system is manually deactivated
■ the bonnet is opened
■ the driver's seat belt is unfastened and the driver's door is opened■ the engine temperature is too low
■ the charging level of the vehicle battery is below a defined level
■ the brake vacuum is not sufficient
■ the vehicle is driven at least at walking speed
■ the climate control system requests
an engine start
■ the air conditioning is manually switched on
If the bonnet is not fully closed, a
warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop during restart might be noticeable.
Parking ■ 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. Apply manual parking brake without
pressing release button. Apply asfirmly as possible on downhill or uphill slopes. Depress the foot
brake at the same time to reduce
operating force.
Apply electric parking brake by pulling switch m for approx.
one second.
■ Switch off the engine and ignition. Turn the steering wheel until the
steering wheel lock engages.
■ If the vehicle is on a level surface or
uphill slope, engage first gear or set the selector lever to P 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 or set the selector lever to P before switching
off the ignition. Turn the front
wheels towards the kerb.
■ Lock the vehicle and activate the anti-theft alarm system.

Flex Ride
Flex Ride driving system allows the
driver to select between three driving
modes:
■ SPORT mode: press button SPORT , LED illuminates.
■ TOUR mode: press button TOUR,
LED illuminates.
■ NORMAL mode: both buttons SPORT and TOUR are not
pressed, no LED illuminates.
Deactivate SPORT mode and TOUR
mode by pressing corresponding
button once more.
In each driving mode Flex Ride networks the following electronic
systems:
■ Continuous Damping Control.
■ Accelerator Pedal Control.
■ Steering Control.
■ Electronic Stability Control (ESC).
■ Antilock brake system (ABS) with cornering brake control (CBC).
■ Automatic transmission.
148Driving and operating
SPORT mode
The settings of the systems are
adapted to a sportier driving style:
■ Damping of shock absorbers reacts
more stiffly to provide better contact with the road surface.
■ The engine reacts more quickly to the accelerator pedal.
■ Steering support is reduced.
■ Shift points of automatic transmission occur later.
■ With SPORT mode activated, the illumination of main instruments
changes from white to red.
TOUR mode
The settings of the systems are
adapted to a comfort driving style:
■ Damping of shock absorbers reacts
more softly.
■ Accelerator pedal reacts with standard settings.
■ Steering support is in standard mode.
■ Shift points of automatic transmission occur in a comfort
mode.
■ Illumination of main instruments is white.
NORMAL mode
All settings of the systems are
adapted to standard values.
Drive mode control Within each manually selected drivingmode SPORT, TOUR or NORMAL,
the Drive Mode Control (DMC)
detects and analyses continuously
the real driving characteristic,
responses by the driver, and the
active dynamic state of the vehicle. If
necessary, the control unit of DMC
automatically changes the settings
within the selected driving mode or,
when recognising greater variations,
the driving mode is changed for the
length of variation.
If, for example, NORMAL mode is
selected and DMC detects a sporty
driving behaviour, DMC changes
several settings of the Normal mode
into sporty settings. The DMC
changes to SPORT mode in case of
very sporty driving behaviour.
If, for another example, TOUR mode
is selected and whilst driving on a
winding road a sudden hard brake is
necessary, DMC will detect the

Fault
In the event of a fault in the system or if the system does not work due to
temporary conditions like snow
covered sensors, a message is
displayed in the Driver Information
Centre.Advanced parking assist
The advanced parking assist system
manoeuvres the driver into a parking slot by giving instructions on the
Driver Information Centre and
acoustic signals. The driver has to
control acceleration, braking, steering
and gear shifting.
The system uses the sensors of the
front-rear parking assist in
combination with two additional
sensors on both sides of the front and rear bumper.
Button D

Advanced parking assist and front-
rear parking assist, see description
before, both will be operated by
button D.
Short press of button D activates or
deactivates the parking assist.
Long press of button D (approx. one
second) activates or deactivates the
advanced parking assist.
Button logic operates the systems by
pressing as following:
■ front-rear parking assist is active: short press deactivates front-rear
parking assist.
■ front-rear parking assist is active: long press activates advanced

160Driving and operating
The instructions in the display show:■ a hint when driving faster than 18 mph,
■ the demand to stop the vehicle, when a parking slot is detected,
■ the direction of driving during the parking manoeuvre,
■ the steering wheel position during parking,
■ for some of the instructions a progress bar is shown.A successful parking manoeuvre is
indicated by the End position symbol.
Pay attention always to the sound of
the front-rear parking assist.
Continuous sound means that the
distance to an obstacle is less than about 30 cm.
Changing the parking side
The system is configured to detect
parking slots by default on the
passenger side. To detect parking
slots on the driver side, switch on turn
indicator to the driver side for the
duration of searching.
As soon as turn indicator is switched
off, the system searches for parking
slots on the passenger side again.

■ switching off the ignition
168Driving and operatingsigns. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern any
other than the conventional traffic signs that might give or end a
speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
■ no operation of turn signals
■ no brake pedal operation
■ no active accelerator operation or speeding-up
■ no active steering
If the driver is performing these
actions, no warning will be issued.

172Driving and operatingTrailer 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.
The bulb outage detection function for
trailer brake light cannot detect a
partial bulb outage, e.g. in case of 4 x
5 Watt bulbs, the function only detects
lamp outage when only a single
5 Watt lamp remains or none remain.
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.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.
For trailers with low driving stability
and caravan trailers with a permitted
gross vehicle weight of more than
1200 kg the use of a stabiliser is
strongly recommended when driving
above 50 mph.
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 3 234.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).
Vehicle care181Engine coolantThe coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37 °C.Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be above the
filling line mark. Top up if the level is
low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Power steering fluidCaution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap/dipstick or
from entering the reservoir.
