Problems with "Pre-entry climate control via SmartKey"
ProblemPossible causes/consequences andMSolutions
"Pre-entry climate con-
trol via SmartKey" can-
not be switched on or
has switched itself off.The condition of charge of the high-voltage battery is under the speci-
fied minimum condition of charge.
XStart the engine when the vehicle is at a standstill.
The engine powers the electric motor. The electric motor operates
as a generator. The high-voltage battery is being charged.
Further information on charging the high-voltage battery via:
Ra mains socket (Ypage 183)
Ra charging station (Ypage 186)
Ra wallbox (Ypage 185)
"Pre-entry climate control via SmartKey" has been started more than
twice with the engine switched off.
XSwitch on the engine and let it run for more than ten seconds.
XTry again to switch on "Pre-entry climate control via SmartKey".
Pre-entry climate control at time of
departure
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
The "Pre-entry climate control at departure
time" function is only available in PLUG-IN
HYBRID vehicles.
You can use the "Pre-entry climate control at
departure time" function to cool or heat the
vehicle interior if the engine is not running.
The "Pre-entry climate control at departure
time" function can be activated regardless of
whether or not the vehicle is connected to an
electric power supply. The condition of charge of
the high-voltage battery must be higher than the
specified minimum condition of charge, how-
ever.
When the vehicle is connected to an electric
power supply, priority is given to charging the
high-voltage battery to the specified minimum charge. "Pre-entry climate control at departure
time" is only activated subsequently.
The running time of the "Pre-entry climate con-
trol at departure time" function may be reduced
if:
Rthe vehicle is not connected to an electric
power supply and
Rthe high-voltage battery is not fully charged
With active "Pre-entry climate control at depar-
ture time" the condition of charge of the high-
voltage battery can be reduced, even if the
charge cable connector is connected.
When the vehicle is cooled, the following func-
tions are activated if required:
RClimate control system
RBlower
RSeat ventilation
When the vehicle is heated, the following func-
tions are activated if required:
RClimate control system
RBlower
RSeat heating
RSteering wheel heating
RArmrest heating
RExterior mirror heating
RRear window defroster

Engine running while vehicle is stationary
The combustion engine is running while the
vehicle is stationary. The high-voltage battery is
not being charged.
The arrows for the energy flow are not shown.
The combustion engine is highlighted.
Charging while vehicle is stationary
The engine powers the electric motor. The elec-
tric motor operates as a generator. The high-
voltage battery is being charged.
The arrow representing energy flow is shown in
white.
Driving using the engine
The engine powers the vehicle.The arrows for the energy flow are shown in
white.
Driving using the engine plus boost mode
If you rapidly depress the accelerator, the elec-
tric motor supports the internal combustion
engine by providing additional torque.
The arrows for the energy flow are shown in red.
Driving using the engine plus energy
recovery
The engine powers the vehicle. The electric
motor is operating as a generator, e.g. in over-
run mode and when braking (
Ypage 253). The
kinetic energy of the vehicle is converted into
electrical energy. The high-voltage battery is
being charged.
The arrows for the energy flow are shown in
green.

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
taking place (
Ypage 240). 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 81 mph
(130 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 252).
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.
The internal combustion engine will be switched
off automatically, if:
Rthe driver removes his or her foot from the
accelerator pedal in drive program Eand a
speed of 81 mph (130 km/h) is not exceeded
Rthe driver removes his or her foot from the
accelerator pedal in drive program E+and a
speed of 112 mph (180 km/h) is not excee-
ded
Further information on the automatic engine
switch-off (
Ypage 252).
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 253).
All vehicle systems remain active, e.g. the auto-
matic climate control.
The ECO start/stop function is only available in
drive programs Eand E+. Electric-only operation
is only possible in drive programs Eand E+.
Additional information for drive programs Eand
E+ (
Ypage 250).
Automatic engine switch-off
The engine is switched off automatically, includ-
ing when:
Rthe driver removes his or her foot from the
accelerator pedal in drive program Eand a
speed of 81 mph (130km/ h)is not exceeded
(
Ypage 253)
Rthe driver removes his or her foot from the
accelerator pedal in drive program E+and a
speed of 112 mph (180 km/h) is not excee-
ded (
Ypage 253)
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
