Driving tips
Holding the vehicle stationary on uphill
gradients Do not hold the vehicle stationary on uphill gra-
dients by depressing the accelerator pedal.
Instead, only ever hold the vehicle stationary on
uphill gradients by:
R depressing the brake pedal
R engaging the electric parking brake
Kickdown Use kickdown for maximum acceleration:
X Depress the accelerator pedal beyond the
pressure point.
The needle in the power display points to the
boost area (Y page 173).
X Ease off the accelerator pedal once the
desired speed is reached. i
Maximum acceleration is available for a limi-
ted time. Program selector button

D
- Sporty driving or driving on a
downhill gradient
The brake pedal does not need to
be used as often because the
extent of the deceleration is
greater than in D.
Energy use when decelerating is
considerably higher than when
the vehicle is braked with the
brake pedal. D
AUTO
(radar-
based) The intensity of recuperation is
automatically adjusted to the cur-
rent traffic situation.
Default setting In levels
Dand D-
, deceleration can be control-
led in an infinitely variable manner using the
accelerator pedal.
The braking performance of the electric motor
using recuperative braking is, in some operating modes, either reduced or not effective:
R when the charge status of the high-voltage
battery increases
R if the high-voltage battery is not yet at a nor-
mal operating temperature
R when driving close to the maximum design
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.
Radar-based recuperation The vehicle uses the sensors of COLLISION PRE-
VENTION ASSIST PLUS during radar-based
recuperation (D AUTO
). The sensors detect the
distance to the vehicle ahead and its speed. The intensity of recuperation is then automatically
adjusted to the current traffic situation.
The range can then be increased by storing
energy efficiently. Adjustment is infinitely vari-
able from overrun mode (no recuperation) to
maximum recuperation.
Maintain sufficient distance to the vehicle in
front. Mercedes-Benz recommends that you activate COLLISION PREVENTION ASSIST PLUS
as a visual and acoustic aid.
Examples of radar-based recuperation:
R Approaching a slower vehicle, a decelerating
vehicle or when following a vehicle downhill.
Your vehicle decelerates slightly and increa-
ses recuperation.
R Driving when no vehicle is detected in front or
when a vehicle is detected in the far distance or an accelerating vehicle is detected. Your
vehicle switches to overrun mode at higher
speeds.
R Driving on a steep downhill slope. Accelera-
tion downhill is reduced and recuperation is
increased. This is comparable with shifting
down when driving downhill.
X To activate radar-based recuperation: pull
steering wheel gearshift paddle :or;
towards you and hold for about one second.
X To deactivate radar-based recuperation:
briefly pull steering wheel gearshift paddle
:
or ; towards you.
If you change between radar-based and manual
recuperation, the following levels are activated
depending on the selection via the steering
wheel gearshift paddles: :
Steering wheel
gearshift paddle - selects
D-
(maximum
recuperation) ;
Steering wheel
gearshift paddle + selects
D+
(overrun) In particular, the function of the radar sensors
can be impaired in the case of:
R
dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
Following damage to the front end of the vehicle, have the radar sensor settings and operation
checked at a qualified specialist workshop
immediately. This also applies to collisions at
slow speeds where there is no visible damage to the front of the vehicle.
If the radar sensors are not available, the system
switches automatically to level Dwith moderate Transmission

recuperation. Have the radar sensors checked
at a qualified specialist workshop immediately.
Automatic adjustment of recuperation
on downhill gradients The vehicle can detect steep downhill gradients.
To reduce acceleration downhill and to charge
the high-voltage battery, recuperation is
increased steplessly. This is comparable to the
engine brake in a combustion engine when you
downshift a gear on a downhill gradient.
Automatic adjustment of recuperation on down-
hill gradients is available in level DAUTO
or on
vehicles without steering wheel gearshift pad-
dles in level D.
Intelligent recuperation The vehicle uses the map and camera data of
Traffic Sign Assist in addition to the sensors of
COLLISION PREVENTION ASSIST PLUS during
radar-based recuperation ( DAUTO
). The rate of
recuperation is then automatically adjusted to
the current traffic situation, taking the current
and future maximum speed into account. High-voltage battery
Important safety notes
G
DANGER
The vehicle's high voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Do not touch any high-voltage components
after an accident and never modify the vehi-
cle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system
checked by a qualified specialist workshop. G
WARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery could exceed a critical value. In this case, flammable gas
escapes through a vent valve in the vehicle's
underbody. The gas can ignite. There is a risk of injury.
Leave the danger area immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements. G
DANGER
Connecting the charging cable to the mains
supply via incorrectly installed mains sockets or by means of adapters, extension cables or
similar could cause a fire or an electric shock. There is a risk of fatal injury.
To avoid such risks, observe the following:
R Only connect the charging cable to mains
sockets:
- which have been properly installed and
- which have been inspected by a qualified
electrician
R For safety reasons, only use charging
cables which have been supplied with the
vehicle or which have been approved for
this vehicle.
R Never use a damaged charging cable.
R Do not use:
- extension cables
- extension reels
- multi-outlet sockets
R Never use socket adapters to connect the
charging cable to the mains socket. The
only exception is if the adapter has been
tested and approved by the manufacturer
for charging the high-voltage battery of an
electric vehicle.
R Observe the safety notes in the operating
instructions for the socket adapter. G
DANGER
Connecting the charging cable to the wallbox via an incorrectly installed wallbox or adapter,
extension cable or similar could cause a fire or an electric shock. There is a risk of fatal injury. 134

WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving.
Your vehicle is powered by an electric motor.
The electric motor draws the energy required to
drive the vehicle from the high-voltage battery.
When braking and rolling, kinetic energy is con- verted into electrical energy by energy recovery
and stored in the high-voltage battery.
The range of the vehicle is reduced when con-
sumers are switched on, e.g. THERMOTRONIC. Driving tips
