time and immediate pre-entry climatecontrol
Important safety notes
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
General notes
Using the "Pre-entry climate control at depar-
ture time" function, you can cool or heat the
vehicle interior prior to the desired departure
time.
When using the "Pre-entry climate control at
departure time" function, the condition of
charge of the high-voltage battery must be
higher than the specified minimum condition
of charge.
The running time of the climate control may
be reduced if:
Rthe vehicle is not connected to an electric
power supply
Rthe high-voltage battery is not fully charged
With active "Pre-entry climate control at
departure time" the condition of charge of the
high-voltage battery can be reduced, even if
the charge cable connector is connected.
In certain situations, the desired interior tem-
perature cannot be reached.
When the vehicle is cooled, the following
functions are activated as necessary:
RClimate control system
RCooling with air dehumidification
RBlower
When the vehicle is heated, the following
functions are activated as necessary:
RClimate control system
RBlower
RSeat heating
RWindshield heating
RRear window defroster
"Immediate pre-entry climate control" is auto-
matically switched off when operational read- iness mode is requested.
Setting the departure time
You can set a departure time for the "Pre-
entry climate control at departure time". Your
vehicle will then be cooled or heated until the
desired temperature is reached in time for the
set departure time. "Pre-entry climate control
at departure time" will be activated a maxi-
mum of 35 minutes before departure. If the
departure is delayed, the vehicle will be
heated or cooled for a further five minutes.
You can set the desired departure time in the
E-CELL
submenu on the on-board computer
(
Ypage 195).
Activating immediate pre-entry climate
control
You can activate "Immediate pre-entry cli-
mate control" even if the vehicle interior is
already at the desired temperature. This
means that the vehicle interior continues to
be cooled or heated, e.g. if the journey is
interrupted for up to 50 minutes, and the inte-
rior temperature is kept constant. You can
only set the desired temperature using the
climate control unit. If you do not pre-select a
temperature, the last temperature set will be
automatically adopted.

Drive program E+is characterized by the fol-
lowing:
Rreduced torque and significantly reduced
power. This supports an especially efficient
and even driving style and results in a
reduction in speed to approximately
70 mph (110km/ h).
Rthe vehicle pulling away more gently in

: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 (
Ypage 68).
XTo decrease recuperation:
pull right-hand
steering wheel paddle shifter ;.
XTo increase recuperation:pull left-hand
steering wheel paddle shifter :.
The various recuperation levels are shown in
the transmission position display once Dhas
been selected (
Ypage 134).
The following recuperation levels are availa-
ble in overrun mode:
Rno recuperation (D+, coasting mode)
Rmoderate recuperation (D )
Rhigh recuperation (D-)
Rrecuperation depending on the traffic sit-
uation (DAUTO, radar-based)
You can see the intensity of recuperation in
overrun mode by reading the recuperation
performance value shown in the power dis-
play (
Ypage 183).
Every time drive position Dis selected, the
transmission switches into recuperation level
D
AUTOautomatically.
138Transmission
Driving and parking

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.
DNormal driving
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 inD.
Energy use when decelerating is
considerably higher than when
the vehicle is braked with the
brake pedal.
DAUTO
(radar-
based)
The intensity of recuperation is
automatically adjusted to the
current traffic situation.
Default setting
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:
Rwhen the condition of charge of the high-
voltage battery increases
Rif the high-voltage battery is not yet at a
normal operating temperature
Rwhen driving close to the maximum design
speed
Rwhen the vehicle is almost stationary
Rin transmission position N
Rduring 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:
RApproaching a slower vehicle, a decelerat-
ing vehicle or when following a vehicle
downhill. Your vehicle decelerates slightly
and increases recuperation.
RDriving 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.
RDriving on a steep downhill slope. Acceler-
ation downhill is reduced and recuperation
is increased. This is comparable with shift-
ing down when driving downhill.
XTo activate radar-based recuperation:
pull steering wheel paddle shifter :or;
towards you and hold for about one second.
XTo deactivate radar-based recupera-
tion: briefly pull steering wheel paddle
shifter :or; towards you.

Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, fo r example, the power steering and thebrake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do no t switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements fo rth ecoun-
tr y in which you are driving. Some jurisdic-
tion s prohibit the driver from usingamobile
phone while drivin gavehicle.
If you makeacall while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 ft (approximately 14 m) per
second.
Drive sensibly – save energy
Observe the following tips to save energy:
RThe tires should always be inflated to the
recommended tire pressure.
RRemove unnecessary loads.
RRemove roof racks when they are not nee-
ded.
RAvoid frequent acceleration or braking. Energ
y consumption also increases when
driving in low or high outside temperatures, in
stop-start traffic, on short journeys and in
hilly terrain .
Drinking and driving
GWARNING
Drinking and drivin gand/o rtaking 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 no t drink or take drugs and drive or allow
anyone to drive who has been drinkingor tak-
ing drugs.
ECO display
The ECO display provides feedback on how
economical your driving characteristics are.
The ECO display assists you in achieving the
most economical driving style for the selec-
te d settings and prevailing conditions. Your
driving style can significantly influence the
vehicle's consumption .
The ECO display consists of three bars:
RAcceleration
RConstant
RCoasting
The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%. A higher percent-
age indicates a more economical driving
style.
Driving tips157
Driving and parking
Z

The ECO display does not indicate the actual
fuel consumption. A fixed percentage count
in the ECO display does not indicate a fixed
consumption.
Apart from driving style, consumption is
dependent on many factors such as, e.g.:
Rload
RTire pressure
Rcold start
Rchoice of route
Relectrical consumers switched on
These factors are not included in the ECO dis-
play.
The evaluation of your driving style is carried out using the following three categories:
RAcceleration(evaluation of all accelera-
tion processes):
-The bar fills up: moderate acceleration,
especially at higher speeds
-The bar empties: sporty acceleration
RConstant(assessment of driving behavior
at all times)
-The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
-The bar empties: fluctuations in speed
RCoasting(assessment of all deceleration
processes)
-The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
-The bar empties: frequent braking
To achieve a higher value in the categories
Acceleration
and Constant, drive the vehi-
cle in drive program E+orE.
On long journeys at a constant speed, e.g. on
the highway, only the bar for Constant
will
change.
The ECO display summarizes the driving char-
acteristics from the start of the journey to its
completion. For this reason, the bars change
dynamically at the beginning of the journey.
On longer journeys, there are fewer changes. For more dynamic changes, carry out a man-
ual reset.
For further information on the ECO display,
see (
Ypage 187).
Braking
Important safety notes
GWARNING
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 effec- tive:
Rwhen the condition of charge of the high-
voltage battery increases
Rif the high-voltage battery is not yet at a
normal operating temperature
Rwhen driving close to the maximum speed
Rwhen the vehicle is almost stationary
Rin transmission position N
Rduring 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.
Downhill gradients
On long, steep gradients, you must reduce the
load on the brakes by selecting maximum
recuperation. This helps you to avoid over-
heating the brakes and wearing them out
excessively.
Recuperation allows the vehicle to be decel-
erated without placing a load on the braking
system.
158Driving tips
Driving and parking

All checks and maintenance work on the
brake system must be carried out at a quali-
fied specialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the function-
ality of your brakes at regular intervals.
You can find a description of Brake Assist
(BAS) on (
Ypage 63).
Mercedes-Benz recommends that you only
have brake pads/linings installed on your
vehicle which have been approved for
Mercedes-Benz vehicles or which correspond
to an equivalent quality standard. Brake
pads/linings which have not been approved
for Mercedes-Benz vehicles or which are not
of an equivalent quality could affect your vehi-
cle's operating safety.
Mercedes-Benz recommends that you only
use brake fluid that has been specially
approved for your vehicle by Mercedes-Benz,
or which corresponds to an equivalent quality
standard. Brake fluid which has not been
approved for Mercedes-Benz vehicles or
which is not of an equivalent quality could
affect your vehicle's operating safety.
Checking brake lining thickness
You can measure the break pad/lining thick- ness using a test gage. Color-coding (green or
red) on the test gage allows you to determinewhether the brake pad/lining thickness is still
sufficient. The test gage is in the vehicle docu-
ment wallet in the glove box.

Cruise Control
General notes
Cruise control maintainsaconstant road
speed for you. It brakes automatically in order to avoid exceeding the set speed. Change into
transmission position D
-(Ypage 138) on long
and steep downhill gradients. This increases
recuperation in overrun mode. This relieves
th e load on the brake system and prevents
th ebrake s from overheating and wearing too
quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed foraprolonged period. You can
store any road speed above 20 mph
(30 km/ h).
The speed indicated in the speedometer may
differ slightly from the speed stored.
Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
control cannot take into account the road,
traffic and weather conditions. Cruise control
is only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed,
for braking in good time and for staying in
your lane.
Do not use cruise control:
Rin road and traffic conditions which do not
allow you to maintain a constant speed e.g.
in heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel- erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored.
