Rthat are parallel to the direction of travel andat least 39.5 in (1.0 m)longer than your vehi-
cle
Rthat are at right angles to the direction of
travel and at least 39.5 in (1.0 m) wider than
your vehicle
iNote that Active Parking Assist cannot
measure the size of a parking space if it is at
right angles to the direction of travel. You will
need to judge whether your vehicle will fit into the parking space.
When driving at speeds below 19 mph
(30 km/h), you will see the parking symbol as a
status indicator in the instrument cluster. When
a parking space has been detected, an arrow
towards the right or the left also appears. By
default, Active Parking Assist only displays park-
ing spaces on the front-passenger side. Parking
spaces on the driver's side are displayed as
soon as the turn signal on the driver's side is
activated. When parking on the driver's side,
this must remain switched on until you acknowl-
edge the use of Active Parking Assist by press-
ing the abutton on the multifunction steer-
ing wheel. The system automatically determines
whether the parking space is parallel or at right
angles to the direction of travel.
A parking space is displayed while you are driv-
ing past it, and until you are approximately 50 ft (15 m) away from it.
Parking
GWARNING
If you leave the vehicle when it is only being
braked by Active Parking Assist it could roll
away if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected.
Rthe accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
Before leaving the vehicle, always secure it
against rolling away.
iWhen PARKTRONIC detects obstacles,
Active Parking Assist brakes automatically
during the parking process. You are respon-
sible for braking in good time.

204Driving systems
Driving and parking

drive system automatically selects the most effi-
cient operating mode for every driving situation.Drive the vehicle in the usual manner.
To save fuel in HYBRIDmode, the hybrid drive
system switches off the combustion engine as
often as possible during the journey when power
output requirements are low. When power out-
put requirements are low, the electric motor
powers the vehicle. When power output require-
ments are high, the combustion engine is auto-
matically switched on. The engine is usually
switched off when the vehicle is stationary. Con-
sequently, there is usually no engine idling as
with combustion engine vehicles.
For pulling away and accelerating, the electric
motor supports the internal combustion engine
using the power stored in the high-voltage bat-
tery. In addition, the power is used for partially
electric driving, operation of the electric coolant compressor and to support the 12 V on-board
electrical system. In this way the hybrid drive
system helps to reduce your vehicle's fuel con-
sumption.
Observe the driving tips on plug-in hybrid oper-
ation (
Ypage 230).
Recuperative Brake System
If you release the accelerator pedal when the
vehicle is in motion, overrun recuperation is ini-
tiated. The electric motor is operated as a gen-
erator when in overrun mode and when you
brake. Hybrid technology converts the kinetic
energy of the vehicle into electricity and stores
it in the high-voltage battery.
Observe the important safety notes for the
Recuperative Brake System (
Ypage 45).
Important safety notes
If the engine is switched off by the ECO start/
stop function and you open the driver's door:
Ra message appears in the multifunction dis-
play and
Ra warning tone sounds
Further information (
Ypage 272).
All of the vehicle's systems remain active, if:
Rthe vehicle is stationary
Rthe combustion engine is switched off and
Rthe READY indicator in the instrument cluster
lights up If you remove your foot from the brake pedal
while in transmission position D or R, the vehicle
may pull away automatically.
Observe the notes on the READY display of the
ECO start/stop function (
Ypage 231).
Vehicles with an electric motor generate much
less driving noise than vehicles with internal
combustion engines. As a result, your vehicle
may not be heard by other road users in certain
situations. This is the case, for example, when
you are parking and your vehicle is not seen by
other road users.
This requires you to adopt a particularly antici-
patory driving style, as it is necessary to allow
for the possibility that other road users may
behave erratically.
Displays and operation
Electric motor performance display
The power display for the electric motor is loca-
ted on the right-hand side of the instrument
cluster.
RArea :to; (E-DRIVE):
This shows the electric output from the elec-
tric motor, e.g. during electric operation or in
boost mode.
When the motor is switched on, the display is
at limit :. With increasing pressure on the
accelerator pedal the display fills up from :
to ;.
Driving with the electric motor: when the
display reaches limit ;, the combustion
engine is switched on. If the display is
approaching limit ;and you remove your
foot from the accelerator pedal, the display
empties again. The combustion engine is not
switched on. At low speeds, you can thereby

control the electric operation usage so that
you only drive in electric mode.
Driving with the combustion engine:the
electric motor supports the combustion
engine by providing additional torque (boost
mode) until the display reaches limit ;.
You can also select the operating mode of the
hybrid drive system (
Ypage 226).
RArea =to? (CHARGE):
This shows the recuperated energy which is
stored in the high-voltage battery as electrical energy.
When the display reaches limit ?, the maxi-
mum recuperative braking power has been

Overrun mode or braking
There are three possible operating modes when
the hybrid vehicle is decelerating:
Renergy recovery takes place even when the
vehicle is decelerating purely in overrun mode
(
Ypage 225). The electric motor operates as
a generator and stores the recovered energy
in the high-voltage battery
Rwhen the brakes are applied lightly, the vehi-
cle is slowed down further by the electric
motor This increases the energy recovery tak-
ing place (
Ypage 225) The electric motor
operates as a generator and stores the recov- ered energy in the high-voltage battery.
Rwhen the brakes are applied with greater
force, the service brakes are also used to slow
the vehicle down. The two systems work
together
Urban driving
Energy is recuperated during frequent deceler-
ation and stopping in city traffic.
The vehicle can be driven by the electric motor
alone up to a speed of approximately 120 km/ h.
The vehicle is driven by the electric motor alone
only when all conditions for the automatic
engine switch-off are fulfilled.
Further information on the automatic engine
switch-off (
Ypage 231).
Driving on inter-urban roads
The following phases are possible when driving
on inter-urban roads:
Rrapid acceleration (boost mode)
Rconstant energy consumption
Renergy recuperation
Relectric operation mode
A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving
During highway driving, fuel consumption and
emissions are favorably influenced in particular
by reduced power losses.
If the driver removes his foot from the acceler-
ator pedal in drive program Eand a speed of
160 km/h is not exceeded, the combustion
engine is automatically switched off.
Further information on the automatic engine
switch-off (
Ypage 231).
ECO start/stop function
General notes
The ECO start/stop function switches the inter- nal combustion engine off automatically when
the vehicle stops moving and at high speeds
(
Ypage 232).
All vehicle systems remain active, e.g. the auto-
matic climate control.
The ECO start/stop function is only available in
drive programs Cand E. Electric-only operation
is only possible in drive programs Cand E. Addi-
tional information for drive programs
(
Ypage 229).
Automatic engine switch-off
The engine is switched off automatically, includ-
ing when:
Rthe driver removes his foot from the acceler-
ator in drive program Eand a speed of
160 km/h is not exceeded (
Ypage 232)
Rthe engine has reached its operating temper- ature
Rthe driver’s seat belt is fastened and the
driver’s door is closed
Rthe driver only slightly depresses the accel-
erator pedal in order to, for example, maintain
the current speed for a limited distance
Rthe hood is closed and engaged properly
Rthe high-voltage battery is charged suffi-
ciently
Rno malfunctions are present in the hybrid
drive system
The internal combustion engine will not be
switched off automatically, if:
Rthe self-diagnosis function of the engine con-
trol unit is still active
Rthere is a malfunction in the hybrid drive sys-
tem
Rthe climate control of the vehicle requires it
Rthe high-voltage battery is being charged
