Energy recovery: CHARGE
The high-voltage battery of the hybrid system is
charged through energy recovery.
The electric motor acts as a generator and con‐
verts the kinetic energy of the vehicle into elec‐
tric current.
Charging can take place in various situations:▷When the vehicle is rolling if the accelerator
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 your vehicle.
Auto Start/Stop function
The Auto Start/Stop function, refer to
page 66, 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 allows the operation of the
automatic climate control even when the com‐
bustion engine is switched off, for instance
when the combustion engine was switched off
by the Auto Start/Stop function.
▷Residual cooling, refer to page 135.▷Auxiliary air conditioning, refer to
page 137Adapting to the course of the road
When destination guidance is active, the hybrid
system uses the navigation data. This makes it
possible to switch off the combustion engine
upon reaching the destination zone even before
reaching the destination.
Pay attention to the notes in Adapting to the
course of the road, refer to page 82.
Display
The displays of the hybrid system, refer to
page 81, provide information about the cur‐
rent state of hybrid operation and show the sys‐
tem activity in a chart.
Energy-saving driving
To save energy while driving, read the following
information:▷Saving fuel, refer to page 161▷Using the hybrid system efficiently, refer to
page 154▷ECO PRO mode, refer to page 162.▷Adapting to the course of the road, refer to
page 82.
Safety information
Read the information on Safety of the hybrid
system, refer to page 287.

Automatic stopping while driving
When reducing speed, the combustion engine
is switched off when the conditions for electric
driving, refer to page 67, are met.
Assistance for the
combustion engine
The combustion engine provides the primary
drive power to move the vehicle.
The electric motor provides assistance as
needed with additional propulsive power.
ASSIST
During normal vehicle operation, the electric
motor assists the combustion engine, depend‐
ing on the situation.
eBOOST
Accelerating quickly, such as when passing, re‐
quires the maximum available power from the
electric motor. To do this, apply extra force to
the accelerator pedal.
Energy recovery: CHARGE
The hybrid system makes it possible to convert
kinetic energy into electrical power, such as
when braking. This recovered energy charges
the high voltage battery. If necessary, this stored
power is output to the electric motor.
The following conditions must be met to recover
kinetic energy:▷The vehicle is moving.▷Selector lever position D, M/S is engaged.▷The high-voltage battery is not fully
charged.
Energy recovery displays in the instrument clus‐
ter, refer to page 81.
Parking brake
The concept
The parking brake is primarily intended to pre‐
vent the vehicle from rolling while parked; it
brakes the rear wheels.
Setting
Pull the switch.
The LED lights up.
The indicator lamp lights up red. The
parking brake is set.
Lower lamp: indicator lamp in Canadian
models
Set the parking brake and further secure
the vehicle as required
Set the parking brake firmly when parking; oth‐
erwise, the vehicle could roll. On steep upward
and downward inclines, further secure the vehi‐
cle, for example, by turning the steering wheel in
the direction of the curb. ◀

Brake force display
The concept▷During normal brake application, the outer
brake lamps light up.▷During heavy brake application, the inner
brake lamps light up in addition.
Active Protection
The concept
The system is used to detect critical driving sit‐
uations that might lead to an accident. In in these
situations, preventative protection measures
are automatically undertaken to minimize the
risk in the event of an accident as much as pos‐
sible.
Critical driving situations may include:
▷Full application of the brakes.▷Severe understeering.▷Severe oversteering.

Driving stability control systemsVehicle 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.
Antilock Brake System ABS
ABS prevents locking of the wheels during brak‐
ing.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. It thus helps to achieve the shortest
possible braking distance during full braking.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
Drive-off assistant
This system supports driving away on gradients.
The parking brake is not required.1.Hold the vehicle in place with the foot brake.2.Release the foot brake and drive away with‐
out delay.After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driving
without delay, since the drive-off assistant will
not hold the vehicle in place for more than ap‐
prox. 2 seconds and the vehicle will begin rolling
back.◀
DSC Dynamic Stability
Control
The concept
DSC prevents traction loss in the driving wheels
when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Subject
to physical limits, DSC helps to keep the vehicle
on a steady course by reducing engine speed
and by applying brakes at individual wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Indicator/warning lamps The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.Seite 107Driving stability control systemsControls107

Cruise control
The concept
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
It maintains the speed that was set using the
control elements on the steering wheel.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Unfavorable conditions
Do not use the system if unfavorable con‐
ditions make it impossible to drive at a constant
speed, for instance:▷On curvy roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or on
a loose road surface.
Otherwise, you could lose control of the vehicle
and cause an accident.◀

Things to remember when drivingVehicle 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.
Breaking-in period
General information
Moving parts need to be broken in to adjust to
each other.
The following instructions will help achieve a
long vehicle life and good economy.
Engine and differential
Always obey the official speed limit.
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:▷For gasoline engine, 4,500 rpm and
100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode for the initial
miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac‐
tion potential until after an initial breaking-in pe‐
riod.
Drive conservatively for the first
200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and discs. Drive moderately during this break-in
period.
Following part replacement
The same breaking in procedures should be ob‐
served if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
Using the hybrid system
efficiently
The concept
Your vehicle's hybrid system runs automatically.
Through foresighted driving, the hybrid proper‐
ties are used to the full extent, i.e. fuel consump‐
tion and energy recovery are optimized.
Optimizing energy recovery
Types of energy recovery
Energy recovery is used to charge the high-volt‐
age battery. It is important for the supply of elec‐
trical components and thus a prerequisite for
fuel economy. It appears in three stages during
rolling and braking:
Low energy recovery:
When coasting to a halt without
pressing the brake pedal.Seite 154Driving tipsThings to remember when driving154
Online Edition for Part no. 01 40 2 900 579 - 03 12 490

Braking safely
Your vehicle is equipped with ABS as a standard
feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsiveness.
You can still avoid any obstacles with a minimum
of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
Objects in the area around the pedals No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved for
the vehicle and can be properly fixed in place.
Ensure that the floor mats are securely fastened
again after they were removed for cleaning, for
example.◀
Driving in wet conditions
When roads are wet or there is heavy rain, briefly
exert gentle pressure on the brake pedal every
few miles.
Ensure that this action does not endanger other
road users.
The heat generated in this process helps dry the
brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills
Drive long or steep downhill gradients in the gear
in which the least braking is required. Otherwise,the brake system may overheat, resulting in a
reduction in the brake system efficiency.
You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
necessary.
Automatic transmission:
You can increase the engine's braking effect by
shifting down in the manual mode of the auto‐
matic transmission.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and pos‐
sibly even brake failure.◀
Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking. In
addition, steering and brake assist is unavailable
with the engine stopped.◀
Brake disc corrosion
Corrosion on the brake discs and contamination
on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked vehicle
When using the automatic climate control, con‐
densation water develops that exits underneath
the vehicle.
Therefore, traces of condensed water under the
vehicle are normal.

Transmission position P with the igni‐
tion off
When the ignition is switched off, position P
is engaged automatically. When in an auto‐
matic car wash, for example, ensure that the
ignition is not switched off accidentally.◀
The vehicle cannot be locked from the outside
when in transmission position N. A signal is
sounded when an attempt is made to lock the
vehicle.
Transmission position
Transmission position P is engaged automati‐
cally:
▷When the ignition is switched off.▷After approx. 15 minutes.
Headlamps
▷Do not rub dry and do not use abrasive or
caustic cleansers.▷Soak areas that have been soiled e.g. due to
insects, with shampoo and wash off with
water.▷Thaw ice with deicing spray; do not use an
ice scraper.
After washing the vehicle
After washing the vehicle, apply the brakes
briefly to dry them; otherwise, braking action can
be reduced and corrosion of the brake discs can
occur.
Vehicle care
Car care products
BMW recommends using cleaning and care
products from BMW, since these have been
tested and approved.
Car care and cleaning products
Follow the instructions on the container.
When cleaning the interior, open the doors or
windows.
Only use products intended for cleaning vehi‐
cles.
Cleansers can contain substances that are dan‐
gerous and harmful to your health.◀
Vehicle paint
Regular care contributes to driving safety and
value retention.
Environmental influences can act on the vehicle
paint. Tailor the frequency and extent of your car
care to these influences.
Leather care
Remove dust from the leather often, using a
cloth or vacuum cleaner.
Otherwise, particles of dust and road grime
chafe in pores and folds, and lead to increased
wear and premature degradation of the leather
surface.
To guard against discoloration, such as from
clothing, provide leather care roughly every two
months.
Clean light-colored leather more frequently be‐
cause soiling on such surfaces is substantially
more visible.
Use leather care products; otherwise, dirt and
grease will gradually break down the protective
layer of the leather surface.
Suitable care products are available from the
service center.
Upholstery material care
Vacuum regularly with a vacuum cleaner.
If they are very dirty, e.g., beverage stains, use a
soft sponge or microfiber cloth with a suitable
interior cleaner.
Clean the upholstery down to the seams using
large sweeping motions. Avoid rubbing the ma‐
terial vigorously.Seite 290MobilityCare290
