ment is deleted and restarted when continu-
ing the journey, if:
R you switch off the engine
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or to take a break
Displaying the attention level You can have current status information dis-
played in the assistance menu (Y page 327)
of the on-board computer.
X Select the assistance graphics display for
ATTENTION ASSIST using the on-board
computer (Y page 326).
The following information is displayed:
R the length of the journey since the last
break
R the attention level determined by ATTEN-
TION ASSIST ( Attention level
Attention level), dis-
played in a bar display in five levels from
high to low
R If ATTENTION ASSIST is unable to calculate
the attention level and cannot issue a warn-
ing, the System suspended
System suspended message
appears. The bar display then changes the
display, e.g. if you are driving at a speed
below 60 km/h or above 200 km/h. Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 329).
The system determines the attention level
of the driver depending on the setting
selected:
Selection Standard Standard : the sensitivity with
which the system determines the attention
level is set to normal.
Selection Sensitive Sensitive: the sensitivity is set
higher. The attention level detected by
ATTENTION ASSIST is adapted accordingly
and the driver is warned earlier.
When ATTENTION ASSIST is deactivated, the é symbol appears in the multifunction
display in the assistance graphic display.
When ATTENTION ASSIST has been deactiva-
ted, it is automatically reactivated after the
engine has been switched off. The sensitivity selected corresponds to the last selection
activated (standard/sensitive).
Warning in the multifunction display If fatigue or increasing lapses in concentra-
tion are detected, a warning appears in the
multifunction display: ATTENTION ASSIST ATTENTION ASSIST
Take a break!
Take a break!.
In addition to the message shown in the mul-
tifunction display, you will then hear a warn-
ing tone.
X If necessary, take a break.
X Confirm the message by pressing the a
button on the steering wheel.
On long journeys, take regular breaks in good time that allow for adequate recuperation. If
you do not take a break and ATTEN-
TION ASSIST still detects increasing lapses in
concentration, you will be warned again after
15 minutes at the earliest. This will only hap-
pen if ATTENTION ASSIST still detects typical indicators of fatigue or increasing lapses in
concentration.
If a warning is output in the multifunction dis-
play, a service station search is performed in Driving systems

engine by providing additional torque when
the accelerator is depressed rapidly.
Overrun mode or braking
There are three possible operating modes
when the hybrid vehicle is decelerating:
R When coasting and decelerating, energy
recuperation is already taking place
(Y page 287). The electric motor functions
as an alternator and stores the recuperated energy in the high-voltage battery.
R When braking gently, the electric motor
increases the deceleration of the vehicle.
Energy recuperation is increased
(Y page 287). The electric motor functions
as an alternator and stores the recuperated energy in the high-voltage battery.
R During heavy braking, the service brake is
also used to slow down the vehicle. Both
systems work together.
Driving in the city
Energy is recuperated during frequent decel-
eration and stopping in city traffic.
The vehicle can be driven by the electric
motor alone up to a speed of approximately
140 km/h.
The vehicle is driven by the electric motor
alone only when all conditions for the auto-
matic engine switch-off are fulfilled.
Further information on the automatic engine
switch-off (Y page 298).
Driving on inter-urban roads
The following phases are possible when driv-
ing on inter-urban roads:
R rapid acceleration (boost mode)
R constant energy consumption
R energy recuperation
R electric operation mode
Depending on the characteristics of the
route, there may be a lot of recuperated
energy available. This reduces consumption
and emissions. Driving on the motorway
When driving on a motorway, the decrease in
wasted power has a particularly positive
effect on fuel consumption and emissions.
If the driver removes his foot from the accel-
erator pedal in drive program Eand a speed of
160 km/h is not exceeded, the combustion
engine is automatically switched off.
Further information on the automatic engine
switch-off (Y page 298).
ECO start/stop function General notes
The ECO start/stop function switches the
internal combustion engine off automatically
when the vehicle stops moving and at high
speeds (Y page 299).
All vehicle systems remain active, e.g. the
automatic climate control.
The ECO start/stop function is only available in drive programs Cand E. Electric-only oper-
ation is only possible in drive programs Cand
E. Additional information for drive programs
(Y page 295).
Automatic engine switch-off
The internal combustion engine is switched
off automatically if:
R the driver removes his foot from the accel-
erator in drive program Eand a speed of
160 km/h is not exceeded (Y page 299)
R the internal combustion engine has
reached its operating temperature
R the driver's seat belt is fastened and the
driver's door is closed
R the driver only slightly depresses the accel-
erator pedal in order to, for example, main- tain the current speed for a limited distance
R the bonnet is closed and engaged properly
R the high-voltage battery is charged suffi-
ciently
R no malfunctions are present in the hybrid
drive system 298

Ski/snowboard bag
Important safety notes G
WARNING
The skibag in conjunction with the lashing
straps cannot restrain any objects other than skis.
Vehicle occupants could be struck in the
event of sudden braking or an accident, for
instance, if you:
R transport other heavy or sharp-edged
objects in the skibag
R do not secure the skibag with the lashing
straps
There is a risk of accident and injury.
Store only skis in the skibag. Always secure
the skibag with the lashing straps so that it
cannot move around.
A maximum of four pairs of skis or two snow- boards can be transported in the ski/snow-
board bag.
Securing the ski/snowboard bag in the
luggage compartment X
Fold the middle rear seat backrest forwards
(Y page 393).
X Slide the ski/snowboard bag between the
two outside rear seat backrests. Ensure
that the wheels of the ski/snowboard bag
are in the luggage compartment.
X Open the ski/snowboard bag with zip :
and place the skis or snowboards inside it. X
Close the ski/snowboard bag.
X Pull tensioning strap ;tight by the loose
end until the skis or snowboards are held
firmly inside the ski/snowboard bag. X

Important safety notes G
WARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold for- wards, e.g. when braking suddenly or in the
event of an accident.
R The vehicle occupant would thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt cannot protect as intended and
could result in additional injury.
R Objects or loads in the boot/luggage com-
partment cannot be restrained by the seat
backrest.
This poses an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged before every trip.
! When folding the rear seat backrest for-
wards, ensure that there are no items lying
on the seat cushions. These items could
otherwise be damaged or could themselves damage the rear seats. Stowage areas
