2012 BMW ACTIVEHYBRID 5 fuel consumption

BMW ActiveHybridVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.

The concept
The hybrid system makes it possible to optimize
fuel consumption and driving characteristics.
An electric motor assists the combustion en‐
gine. The vehicle can therefore be driven in cer‐
tain driving situations using only electric power,
which reduces fuel consumption.
In addition to this, the electric motor acts like an
alternator: during braking, it converts the vehi‐
cle's kinetic energy into electricity. The current
is stored in the high-voltage battery and is used
to drive the electric motor.
The hybrid system combines the following func‐
tions:▷Acceleration boost.▷Electric driving.▷Energy recovery: conversion and storage of
kinetic energy as electric current.▷Auto Start/Stop function: automatic stop‐
ping and starting the combustion engine
when coasting, breaking and while stopped.▷Electric operation of the automatic climate
control.
Functions
Acceleration boost: ASSIST and
eBOOST
Driving off and accelerating require a lot of en‐
ergy. To reduce fuel consumption during high
acceleration and to optimize acceleration, the
electric motor supports the combustion engine.
For this purpose, the electric motor is supplied
by the high-voltage battery.
Electric driving: eDRIVE
Under certain conditions, refer to page 67, the
vehicle is powered only by the electric motor.
Driving with the combustion engine:
DRIVE
The combustion engine provides the drive
power to move the vehicle. The high-voltage
battery is charged at the same time.
The hybrid system always starts the combus‐
tion engine automatically.

Displays of the hybrid system
Displays in the instrument cluster
The concept
The display depends on the system's operating
condition. The following functions of the hybrid
system are shown in the instrument cluster.▷High-voltage battery charge indicator.▷Electric driving: eDRIVE.▷Acceleration boost: ASSIST and eBOOST.▷Energy recovery: CHARGE.▷Auto Start/Stop function: READY.
High-voltage battery charge indicator
Displays the state of the high-
voltage battery's charge on a
scale from 0 to 1 when drive read‐
iness is active. If the scale indi‐
cates 1, the high-voltage battery
is fully charged.
During normal vehicle operation, the high-volt‐
age battery is charged up to approx. 80 %. This
ensures optimum energy recovery when decel‐
erating or driving downhill.
Even when the scale indicates 0, the hybrid sys‐
tem is always still under high voltage.
Electric driving: eDRIVE When driving with electric power,
the power output of the electric
motor is indicated by arrows.
Depending on the position of the
accelerator pedal, up to four ar‐
rows are displayed simultaneously. The tach‐
ometer pointer stays on 0 rpm.
If all four arrows are already displayed and addi‐
tional power is required, such as for accelera‐
tion, the combustion engine switches on.
Acceleration boost: ASSIST and
eBOOST
ASSIST: the electric motor as‐
sists the combustion engine.
This is indicated by arrows in the
instrument cluster.
eBOOST: all four arrows are dis‐
played when the electric motor reaches maxi‐
mum power output.
Energy recovery: CHARGE The energy recovered is dis‐
played in the tachometer as an
arrow with the symbol +. The
high-voltage battery is charging.
Auto Start/Stop function: READY The READY display indicates
that the vehicle is ready for driv‐
ing.

hybrid system have been used, arrow 2.
One bar stands for one minute. The background
color in the upper bar display shows the driving
mode during the particular period of time.
In addition, the combustion engine's average
fuel consumption is indicated by a line above the
bar display and as a value on the right next to the
graph.
Displaying the energy flow1."Vehicle Info"2."Hybrid"3. "Energy flow"
Energy flow of the hybrid system
The display shows the active components of the
hybrid system and the direction of the flow of
energy.
▷Orange: energy of combustion engine.▷Blue: energy of high-voltage system.
Adapting to the course of the road
When the navigation system destination guid‐
ance is active, the hybrid system uses the navi‐
gation data. This makes it possible to switch off
the combustion engine upon reaching the des‐
tination zone even before reaching the destina‐
tion. The vehicle is powered only by the electric
motor.
The symbol indicates that the vehicle will
switch off the combustion engine when it enters
the destination zone.
Service requirements
Display The driving distance or the time
to the next service is displayed
briefly after the ignition is
switched on.

General information
Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
The implementation of certain measures, driv‐
ing style and regular maintenance can have an
influence on fuel consumption and on the envi‐
ronmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Remove auxiliary mirrors, roof or rear luggage
racks which are no longer required following
use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.Close the windows and glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
raises fuel consumption.
Check the tire inflation
pressure regularly
Check and, if necessary, correct the tire inflation
pressure at least twice a month and before start‐
ing on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
Look well ahead when driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehicle
driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.
Use coasting conditions
When approaching a red light, take your foot off
the accelerator and let the vehicle coast to a halt.
On a downhill gradient, take your foot off the ac‐
celerator and let the vehicle roll.Seite 161Saving fuelDriving tips161
