ATTENTION ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways. It is
active in the 37 mph (60 km/h) to 125 mph
(200 km/h) range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes
ATTENTION ASSIST is only an aid to the driver. It might not always recognize fatigue or increasing
inattentiveness in time or fail to recognize them
at all. The system is not a substitute for a well-
rested and attentive driver.
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or not
occur at all:
Rif the length of the journey is less than approx-
imately 30 minutes
Rif the road condition is poor, e.g. if the surface
is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving style with high cornering speeds or high rates of accel-
eration
Rif you are predominantly driving slower than
37 mph (60 km/h) or faster than 125 mph
(200 km/h)
Rif you are driving with the active Steer Assist
of DISTRONIC PLUS
Rif the time has been set incorrectly
Rin active driving situations, such as when youchange lanes or change your speed
The ATTENTION ASSIST tiredness assessment
is deleted and restarted when continuing the
journey, if:
Ryou switch off the engine
Ryou take off your seat belt and open the driv-
er'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 (Ypage 247) of
the on-board computer.
XSelect the Assistance display for Attention
Assist using the on-board computer
(
Ypage 246).
The following information is displayed:
Rlength of the journey since the last break.
Rthe attention level determined by ATTENTION ASSIST ( Attention Level), displayed in a
bar display in five levels from high to low.
RIf ATTENTION ASSIST is unable to calculate
the attention level and cannot issue a warn-
ing, the System Suspended
message
appears. The bar display then changes the
display, e.g. if you are driving at a speed below
37 mph (60 km/h) or above 124 mph
(200 km/h).

214Driving systems
Driving and parking
Overrun mode or braking
There are three possible operating modes when
the hybrid vehicle is decelerating:
Renergy recovery takes place even when the
vehicle is decelerating purely in overrun mode
(
Ypage 225). The electric motor operates as
a generator and stores the recovered energy
in the high-voltage battery
Rwhen the brakes are applied lightly, the vehi-
cle is slowed down further by the electric
motor This increases the energy recovery tak-
ing place (
Ypage 225) The electric motor
operates as a generator and stores the recov- ered energy in the high-voltage battery.
Rwhen the brakes are applied with greater
force, the service brakes are also used to slow
the vehicle down. The two systems work
together
Urban driving
Energy is recuperated during frequent deceler-
ation and stopping in city traffic.
The vehicle can be driven by the electric motor
alone up to a speed of approximately 120 km/ h.
The vehicle is driven by the electric motor alone
only when all conditions for the automatic
engine switch-off are fulfilled.
Further information on the automatic engine
switch-off (
Ypage 231).
Driving on inter-urban roads
The following phases are possible when driving
on inter-urban roads:
Rrapid acceleration (boost mode)
Rconstant energy consumption
Renergy recuperation
Relectric operation mode
A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving
During highway driving, fuel consumption and
emissions are favorably influenced in particular
by reduced power losses.
If the driver removes his foot from the acceler-
ator 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 (
Ypage 231).
ECO start/stop function
General notes
The ECO start/stop function switches the inter- nal combustion engine off automatically when
the vehicle stops moving and at high speeds
(
Ypage 232).
All vehicle systems remain active, e.g. the auto-
matic climate control.
The ECO start/stop function is only available in
drive programs Cand E. Electric-only operation
is only possible in drive programs Cand E. Addi-
tional information for drive programs
(
Ypage 229).
Automatic engine switch-off
The engine is switched off automatically, includ-
ing when:
Rthe driver removes his foot from the acceler-
ator in drive program Eand a speed of
160 km/h is not exceeded (
Ypage 232)
Rthe engine has reached its operating temper- ature
Rthe driver’s seat belt is fastened and the
driver’s door is closed
Rthe driver only slightly depresses the accel-
erator pedal in order to, for example, maintain
the current speed for a limited distance
Rthe hood is closed and engaged properly
Rthe high-voltage battery is charged suffi-
ciently
Rno malfunctions are present in the hybrid
drive system
The internal combustion engine will not be
switched off automatically, if:
Rthe self-diagnosis function of the engine con-
trol unit is still active
Rthere is a malfunction in the hybrid drive sys-
tem
Rthe climate control of the vehicle requires it
Rthe high-voltage battery is being charged

Cleaning the seat covers
General notes
!Do not use a microfiber cloth to clean covers
made out of real leather, artificial leather or
DINAMICA. If used often, these can damage
the cover.
Note that regular care is essential to ensure that
the appearance and comfort of the covers is
retained over time.
Genuine leather seat covers
!To retain the natural appearance of the
leather, observe the following cleaning
instructions:
RClean genuine leather covers carefully with a damp cloth and then wipe the covers
down with a dry cloth.
RMake sure that the leather does not
become soaked. It may otherwise become
rough and cracked.
ROnly use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a qualified
specialist workshop.
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
Rdifferences in the texture
Rmarks caused by growth and injury
Rslight nuances of color
These are characteristics of leather and not
material defects.
Seat covers of other materials
!Observe the following when cleaning:
Rclean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid).
Rclean cloth covers with a microfiber cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid). Rub
carefully and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning results
depend on the type of dirt and how long it
has been there.
Rclean DINAMICA covers with a damp cloth.
Make sure that you wipe entire seat sec-
tions to avoid leaving visible lines.
