Driving tips
Holding the vehicle stationary on uphill
gradients Do not hold the vehicle stationary on uphill
gradients by depressing the accelerator
pedal. Instead, only ever hold the vehicle sta-
tionary 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 183).
X Ease off the accelerator pedal once the
desired speed is reached.
i Maximum acceleration is available for a
limited time.
Rocking the vehicle free Shifting the transmission repeatedly between
gears Dand Rmay help to free the vehicle if it
has become stuck in slush or snow. The vehi- cle's engine management system limits the
speed to a maximum of 5 mph (9 km/h) when shifting back and forth. To shift back and forth
between transmission positions Dand R, move the DIRECT SELECT lever up and down
past the point of resistance. Program selector button

Manually adjustable recuperation :
Left-hand steering wheel paddle shifter -
; Right-hand steering wheel paddle shifter
+
You can increase or reduce recuperation in
overrun mode using the steering wheel pad-
dle shifters. When you remove your foot from
the accelerator pedal, recuperation occurs.
The electric motor is then used as a alternator and energy is recovered while driving. The
recuperated electrical energy is stored in the
high-voltage battery. A higher energy recu-
peration level means that the vehicle is
braked more powerfully.
If necessary, counteract the reduced regen-
erative braking effect by applying the brake
yourself.
Information on the Recuperative Braking Sys-
tem (Y page 68).
X To decrease recuperation: pull right-hand
steering wheel paddle shifter ;.
X To increase recuperation: pull left-hand
steering wheel paddle shifter :.
The various recuperation levels are shown in
the transmission position display once Dhas
been selected (Y page 134).
The following recuperation levels are availa-
ble in overrun mode:
R no recuperation (D +
, coasting mode)
R moderate recuperation (D)
R high recuperation (D -
)
R recuperation depending on the traffic sit-
uation (D AUTO
, radar-based)
You can see the intensity of recuperation in
overrun mode by reading the recuperation
performance value shown in the power dis-
play (Y page 183).
Every time drive position Dis selected, the
transmission switches into recuperation level
D AUTO
automatically.
The various different levels are to be used
under the following conditions: D
+ Driving without much braking
and without the presence of
obstacles or sharp bends
The vehicle retains the maxi-
mum possible amount of kinetic
energy. D

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
current traffic situation.

In levels
Dand D-
, deceleration can be con-
trolled 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 effec-
tive:
R when the condition of charge of the high-
voltage battery increases
R if the high-voltage battery is not yet at a
normal 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, counter-
act the reduced regenerative braking effect
by applying the brake yourself.
Radar-based recuperation The vehicle uses the sensors of COLLISION
PREVENTION 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 var-
iable 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 decelerat-
ing vehicle or when following a vehicle
downhill. Your vehicle decelerates slightly
and increases recuperation.
R Driving when no vehicle is detected in front
or when a vehicle is detected in the far dis- tance or an accelerating vehicle is detec-
ted. Your vehicle switches to overrun mode
at higher speeds.
R Driving on a steep downhill slope. Acceler-
ation downhill is reduced and recuperation is increased. This is comparable with shift-
ing down when driving downhill.
X To activate radar-based recuperation:
pull steering wheel paddle shifter :or;
towards you and hold for about one second.
X To deactivate radar-based recupera-
tion: briefly pull steering wheel paddle
shifter :or; towards you.
If you change between radar-based and man- ual recuperation, the following levels are acti-
vated depending on the selection via the
steering wheel paddle shifters: ;

They could also operate the vehicle's equip-
ment. There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle. The function of the electric parking brake and
the parking lock is dependent on the on-board voltage. If the on-board voltage is low or if
there is a malfunction in the system, it may
not be possible to apply the released parking
brake or to shift the transmission to the P
position.
X If this is the case, only park the vehicle on
level ground and secure it to prevent it roll-
ing away.
X Shift the transmission to position P.
It may not be possible to release an applied
parking brake if the on-board voltage is low or
there is a malfunction in the system. Contact a qualified specialist workshop.
The electric parking brake carries out a func-
tion check at regular intervals when the drive
system is switched off. The sounds that can
be heard while this is occurring are normal.
