Influences on the charging behavior
and the charge state of the high-volt-
age battery
Terms of use Observe the following notes:
R information on exceptions and limitations in
warranty documentation and in the related
Maintenance Booklet
R maintenance notes for the high-voltage bat-
tery in the Maintenance Booklet
Method of operation The vehicle is equipped with a high-voltage bat-
tery for driving. The high-voltage battery stores
the energy needed to operate the electric motor and releases it again.
The electric motor uses energy that has been
stored in the high-voltage battery when pulling
away, accelerating and during the journey.
In overrun mode (except D+), kinetic energy is
converted by means of energy recuperation into
electrical energy and stored in the high-voltage
battery.
The high-voltage battery can be charged as fol-
lows:
R through energy recuperation while the vehicle
is in motion
R with the charging cable at a mains socket
while the vehicle is stationary
R with the charging cable at a charging station
while the vehicle is stationary
The high-voltage battery can be charged using a
single-phase charging cable in a voltage range
from 100 V to 240 V.
If the condition of charge drops to less than 13%, the high-voltage battery reserve indicator lamp
lights up in the instrument cluster. Charge the
high-voltage battery as soon as possible.
Below a condition of charge of 5%, the perform-
ance of the vehicle is reduced. The vehicle's
high-voltage electrical system switches off at a
condition of charge of 0%.
Use of the pre-entry climate control function
may mean that the high-voltage battery is not
fully charged. High and low outside temperatures Low outside temperatures
The efficiency of the high-voltage battery is sig-
nificantly reduced at very low outside tempera-
tures. The high-voltage battery is then no longer able to provide the normal electrical power out-
put.
High outside temperatures
To prevent damage to the high-voltage battery
due to very high outside temperatures, the max- imum power output of the high-voltage battery
is reduced automatically.
The E-CELL display indicates the maximum
amount of power available (Y page 152).
Notes on battery care Avoid storing or transporting the vehicle in high
temperatures over a long period (e.g. container
transport).
If you park the vehicle and leave it stationary for
longer periods, connect it to a power supply.
Temperatures below 00F813 ‡ (00F825 †) and over
104 ‡ (40 †), which affect the vehicle for a
period of more than seven days, can cause irre- versible damage.
Discharged battery The vehicle's high-voltage electrical system
switches off if the high-voltage battery is com-
pletely discharged. 30 seconds prior to this, you
are informed of the switch-off by the Battery

ond. Driving tips
131Driving and parking Z

Drive sensibly – save energy
Observe the following tips to save energy:
R The tires should always be inflated to the rec-
ommended tire pressure.
R Remove unnecessary loads.
R Remove roof racks when they are not needed.
R Avoid frequent acceleration or braking.
Energy consumption also increases when driv-
ing in low or high outside temperatures, in stop-
start traffic, on short journeys and in hilly ter-
rain.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists you in achieving the most economical driving style

are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel
consumption. The additionally achieved range
displayed under Bonus fr. Start
Bonus fr. Start does not
indicate a fixed consumption reduction.
In addition to driving style, the actual consump- tion is affected by other factors, such as:
R Load
R Tire pressure
R Cold start
R Choice of route
R Active electrical consumers
These factors are not included in the ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
To achieve a higher value in the categories
"Acceleration" and "Constant", drive the vehicle
in drive program E+orE.
On long journeys at a constant speed, e.g. on the highway, only the outer area for "constant" will
change.
The ECO display summarizes the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of a journey. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform a manual rest
(Y page 158).

Important safety notes G
WARNING
If you increase the recuperation level on slip- pery road surfaces, the drive wheels may lose
their traction. There is an increased danger of skidding and accidents.
Do not increase the recuperation level on slip-
pery road surfaces. The braking performance of the electric motor
using recuperative braking is, in some operating
modes, either reduced or not effective:
R when the condition of charge of the high-volt-
age battery increases
R if the high-voltage battery is not yet at a nor-
mal operating temperature
R when driving close to the maximum speed
R when the vehicle is almost stationary
R in transmission position N
R during and after ESP stability control
If you do not make an additional effort to apply
the brake yourself, the braking effect may not be
sufficient. If necessary, counteract the reduced regenerative braking effect by applying the
brake yourself.
Downhill gradients On long, steep gradients, you must reduce the
load on the brakes by selecting maximum recu-
peration. This helps you to avoid overheating the
brakes and wearing them out excessively.
Recuperation allows the vehicle to be deceler-
ated without placing a load on the braking sys-
tem.
Do not depress the brake pedal continuously
while the vehicle is in motion, e.g. causing the
brakes to rub by constantly applying light pres-
sure to the pedal. This results in excessive and
premature wear to the brake pads.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately. Drive on for a short while. This allows the airflow to
cool the brakes more quickly. Driving tips
