2014 BMW ACTIVE HYBRID 3 auxiliary battery

BMW ActiveHybridVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.

The concept The hybrid system makes it possible to opti‐
mize fuel consumption and driving characteris‐
tics.
An electric motor assists the combustion en‐
gine. In certain driving situations, the vehicle
can also be driven using only electric power,
thereby reducing fuel consumption.
In addition to this, the electric motor acts like
an alternator: during braking and coasting, it
converts the vehicle's kinetic energy into elec‐ tricity. The current is stored in the high-voltage
battery and is used to drive the electric motor.
Functions
Electric driving: eDRIVE Under certain conditions, refer to page 70,
the vehicle is powered only by the electric mo‐
tor.
Acceleration boost: ASSIST and
eBOOST
Driving off and accelerating require a lot of en‐
ergy.
To optimize acceleration and to reduce fuel
consumption, the electric motor boosts the
combustion engine. To do this, the electric
motor uses the energy saved in the high-volt‐
age battery.
The ASSIST acceleration boost is automati‐
cally controlled and is not indicated in the in‐
strument cluster.
CoastingThe engine is automatically switched off. This
driving condition is referred to as coasting, re‐
fer to page 70.
Driving with combustion engine:
DRIVE
The combustion engine, refer to page 71,
provides the primary performance to move the
vehicle. If necessary, the high-voltage battery
is charged at the same time.
The hybrid system always starts the combus‐
tion engine automatically.Seite 31BMW ActiveHybridAt a glance31

Energy recovery: CHARGE
The high-voltage battery of the hybrid system
is charged through energy recovery while driv‐
ing.
The electric motor acts as a generator and
converts the kinetic energy of the vehicle into
electric current.
Charging can take place in various situations:▷When the vehicle is coasting if the acceler‐
ator pedal is not pressed.▷During vehicle braking.
When exerting gentle pressure on the brakes,
the vehicle is only braked by the electric motor.
When the brake pedal is depressed further, the
brake system is activated additionally. This is
why only part of the brake energy is used to
charge the high-voltage battery when exerting
firm pressure on the brake.
Foresighted driving and the early reduction of
speed are important to make full use of the hy‐
brid characteristics of the vehicle.
Auto Start/Stop function The Auto Start/Stop function, refer to
page 69, switches the combustion engine off
when coasting, braking and while the vehicle is
stopped. Convenience functions such as the
automatic climate control are supplied by the
high-voltage battery and can remain switched
on.
Auxiliary functions of the automatic
climate control
The hybrid system makes it possible to oper‐ate the automatic climate control prior to driv‐
ing off and with the combustion engine
switched off.
Using the auxiliary air conditioning and residual
cooling functions, the vehicle interior can be
cooled immediately prior to departure and if
the trip is interrupted.
▷Residual cooling, refer to page 154.▷Auxiliary air conditioning, refer to
page 154
Adapting to the course of the road
When the navigation system destination guid‐
ance is active, the hybrid system uses the ex‐
isting navigation data. Hybrid operation adapts
to the specific route sections. These may be:
▷Steep gradients.▷Arrival in the destination zone.
Pay attention to the notes in Adapting to the
course of the road, refer to page 83.
Display
The displays of the hybrid system, refer to
page 81, provide information about the cur‐
rent state of hybrid operation and show the
system activity in a chart.
Energy-saving driving To save energy while driving, read the follow‐
ing information:
▷Saving fuel, refer to page 178.▷Using the hybrid system efficiently, refer to
page 170▷ECO PRO mode, refer to page 179.▷Adapting to the course of the road, refer to
page 83.
Safety information
Read the information on safe handling of the
hybrid system, refer to page 221.

switched on.
The system will only be switched on within the
next 24 hours. After that, it needs to be reacti‐
vated.
Residual cooling
When the automatic climate control has re‐
duced the interior temperature, this tempera‐
ture can be maintained after the engine has
been switched off. This function can be acti‐
vated up to 15 minutes after the engine is
switched off and for a maximum period of 6 mi‐
nutes.
Functional requirement
▷The high-voltage battery is sufficiently
charged.▷External temperature at least ap‐
prox. 59 ℉/15 ℃.Switching on1.Switch off the ignition.2. Press the right side of the button
on the driver's side.
The symbol appears on the automatic cli‐
mate Control Display.
The interior temperature, air flow and air distri‐
bution can be adjusted with the radio-ready
state switched on.
Switch off At the lowest fan speed, press the left
side of the button on the driver's side.
The symbol on the automatic climate Con‐
trol Display disappears.
Auxiliary air conditioning The conceptAuxiliary air conditioning cools the heated ve‐
hicle interior immediately prior to driving off.
The automatic climate control lowers the inte‐
rior temperature with high cooling output.
The auxiliary air conditioning can be switched
on or off using the remote control.
The system is activated for approx. two mi‐
nutes.
