Yo u should bear thefo llowing in mind:
R Do not exceed the permissible roof load and
to wing capacity. Also obser vethete ch nical
data in the printed Owner's Manual.
R Evenly distribute thero of load, and place
heavy objects at the bottom. Also comply with

Depending on the selected recuperation le vel,the
electric mo tor is operated as an alternator when
in ove rrun mode and during braking in order to
ch arge the high-voltage battery while driving. As
soon as youta ke your foot o. the accelerator
pedal when theve hicle is in motion and in trans-
mission position h,recuperation in overrun
mode is initiated.
The higher there cuperation, the more sharply the
ve hicle is braked when coasting and the more
electrical energy is fed into the high-voltage bat-
te ry.
The deceleration in overrun mode may not be suf-
fi cient depending on the driving conditions.
Decelerating toa standstill is not possible. Also
brake with the service brake if necessar y.Alw ays
adapt your speed tothe driving conditions and
ke ep a su1cient distance.
The recuperative brake system has thefo llowing
ch aracteristics:
R supports braking with elect ronically cont rolled
brake forc e boosting R
con verts th e kinetic energy of theve hicle into
elect ric energy
% Ifyo u brake hard, the mechanical brake is
also used. This means that the maximum
re cuperative energy cann otbe reco vered. The
more you drive and brake in an anticipatory
manner, the more e1cient lyenergy can be
re cuperated.

The braking e.ect of the electric mo tor during

ECO Assist can function even more precisely if
th ero ute is adhered towhen route guidance is
active. The basic function is also available without
active route guidance. Not all information and
tra1c situations can be fore seen. The quality
depends on the map data.
ECO Assist is only an aid. The driver is responsible
fo rke eping a safe distance from theve hicle in
front, forve hicle speed and for braking in good
time. The driver must be ready tobrake at all
times, ir respecti veof whe ther the system inter-

The following function is countr y-dependent
and available only in conjunction with an inte-

The route-based operating-mode strategy is active
only in drive prog rams A and;. When
ro ute guidance is active, data on the planned
ro ute is anal ysed. This function can be activated
and deactivated in the multimedia system
(/ page 294).
If th e function is active, data on the fur ther course
of thero ute is evaluated. This includes, e.g. road
type, speed limi tations and altitude data. The
hybrid system then adapts the operating
strategy tothe fur ther course of thero ute:
R Use of electrical energy and the combustion
engine are adap ted.
R State of charge ofthe high-voltage battery is
controlled accordingl y.
R Electrical energy is reser ved especially for

R The vehicle automatically selects the operat-

Exhausti vedischarging can therefore occur if

TE Accelerated ageing of the high-volt-
age battery due tonot observing thefo l-
lowing recommendations As a
result of its basic characteristics, the
storage capacity of and the amount of energy
av ailable from the high-voltage battery decrease
over the course of its life. As a
re sult, the maximum electrical range that can
be achie vedby theve hicle is reduced and its
maximum electrical output can be impaired.
The following factors could accelerate the age-
ing of the high-voltage batter y:
R a high le vel of charge , especially if the
ve hicle is idle for a lengt hyperiod of time
R leaving theve hicle idle for lengt hyperiods
at high ambient temp eratures #
Toavo id accelerated ageing, please
obser vethefo llowing recommendations
when handling the high-voltage batter y. Re
commendations when handling the high-voltage
batter y:
R If leaving theve hicle idle for lengt hyperiods,
park up theve hicle with a high- voltage battery
ch arge leve l between 30% and 50%. Do not
ke ep the high-voltage battery continuously
connected topowe r supply equipment. R
If leaving theve hicle idle for lengt hyperiods of
time avoid, if possible, high ambient temp era-
tures.
R Check the high-voltage battery's charge level
ev ery six weeks (/ page 207).
R Char gethe high-voltage battery if thech arge
le ve l is below 20%.
R Do not disconnect the 12 V battery even if the
ve hicle is leT idle for a lengt hyperiod. Other-
wise, the condition of theve hicle's high- volt-
age battery cannot be monitored.
Yo u can contribute toreducing theve hicle's
