Things to remember when drivingVehicle 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 respectively applicable country
provisions must be observed when using the
respective features and systems.
Breaking-in period General information
Moving parts need time to adjust to one an‐
other (break-in time).
The following instructions will help accomplish
a long vehicle life and good efficiency.
During break-in, do not use the Launch Con‐
trol, refer to page 109.
Engine, transmission, and axle drive
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 load or kickdown under all circum‐
stances.
From 1,200 miles/2,000 km The engine and vehicle speed can gradually be
increased.
Tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
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 optimal per‐
formance between brake discs and brake
pads. Drive moderately during this break-in pe‐
riod.
Following part replacement
The same break-in procedures should be ob‐
served if any of the components above-men‐
tioned have to be renewed in the course of the
vehicle's operating life.
General driving notes
Closing the trunk lid WARNING
An open trunk lid protrudes from the ve‐
hicle and can endanger occupants and other
traffic participants or damage the vehicle in the
event of an accident, braking or evasive ma‐
neuvers. In addition, exhaust fumes may enter
the vehicle interior. There is risk of injuries or
risk of property damage. Do not drive with the
trunk lid open.◀
If driving with the tailgate open cannot be
avoided:▷Close all windows and the glass sunroof.▷Greatly increase the air flow from the vents.▷Drive moderately.Seite 234Driving tipsThings to remember when driving234
Online Edition for Part no. 0140 2 964 330 - VI/15

Hot exhaust systemWARNING
During driving operation, high tempera‐
tures can occur underneath the body, e.g.
caused by the exhaust gas system. If combus‐
tible materials, such as leaves or grass, come
in contact with hot parts of the exhaust gas
system, these materials can ignite. There is
risk of injuries or risk of property damage.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that no combustible materials can come in
contact with hot vehicle parts in driving opera‐
tion, idle or during parking. Do not touch the
hot exhaust system.◀
Mobile communication devices in the
vehicle
WARNING
Vehicle electronics and mobile phones
can influence one another. There is radiation
due to the send operations of mobile phones.
There is risk of injuries or risk of property dam‐
age. If possible, in the car's interior use only
mobile phones with direct connections to an
exterior antenna in order to exclude mutual
disturbance and deflect the radiation from the
car's interior.◀
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Driving through water CAUTION
When driving too quickly through too
deep water, water can enter into the engine
compartment, the electrical system or thetransmission. There is risk of property damage.
When driving through water, do not exceed the
maximum indicated water level and the maxi‐
mum speed for driving through water.◀
Drive through calm water only and only if it is
not deeper than 9.8 inches/25 cm and at this
height, no faster than walking speed, up to
3 mph/5 km/h.
Braking safely Your vehicle is equipped with ABS as a stand‐
ard feature.
Applying the brakes fully is the most effective
way of braking in situations needed.
Steering is still responsive. You can still avoid
any obstacles with a minimum of steering ef‐
fort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
In certain braking situations, the perforated
brake discs can cause functional problems.
However, this has no effect on the perform‐
ance and operational reliability of the brake.
Objects in the movement area around
pedals and floor area
WARNING
Objects in the driver's floor area can limit
the pedal distance or block a depressed pedal.
There is risk of an accident. Stow objects in
the vehicle such that they are secured and
cannot enter into the driver's floor area. Use
floor mats that are suitable for the vehicle and
can be safely attached to the floor. Do not use
loose floor mats and do not layer several floor
mats. Make sure that there is sufficient clear‐
ance for the pedals. Ensure that the floor mats
are securely fastened again after they were re‐
moved, e.g. for cleaning.◀Seite 235Things to remember when drivingDriving tips235
Online Edition for Part no. 0140 2 964 330 - VI/15

Driving in wet conditionsWhen roads are wet, salted, or in heavy rain,
press brake pedal ever so gently every few
miles.
Ensure that this action does not endanger
other traffic.
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 WARNING
Light but consistent brake pressure can
lead to high temperatures, brakes wearing out
and possibly even brake failure. There is risk of
an accident. Avoid placing excessive stress on
the brake system.◀
WARNING
In idle or with the engine switched off,
safety-relevant functions are restricted or not
available anymore, e.g. braking effect of the
engine or braking force and steering support.
There is risk of an accident. Do not drive in idle
or with the engine switched off.◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐
wise the brakes may overheat and reduce
brake efficiency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.
Brake disc corrosion
Corrosion on the brake discs and contamina‐
tion on the brake pads are furthered by the fol‐
lowing circumstances:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.Corrosion will built up when the maximum
pressure applied to the brake pads during
braking is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops collecting under‐
neath the vehicle.
These traces of water under the vehicle are
normal.Seite 236Driving tipsThings to remember when driving236

Saving fuelVehicle features and optionsThis 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 respectively applicable country
provisions must be observed when using the
respective features and systems.
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.
Carrying out certain measures, such as a mod‐
erate driving style and regular maintenance,
can influence fuel consumption and 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.
Tires General information
Tires can affect fuel consumption in various
ways, e.g., tire size may influence fuel con‐
sumption.
Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflation
pressure at least twice a month and before
starting 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 quickest way of warming the cold
engine up to operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and proactively reduces fuel
consumption.Seite 240Driving tipsSaving fuel240
Online Edition for Part no. 0140 2 964 330 - VI/15

Avoid high engine speeds
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
If necessary, observe the gear shift indicator,
refer to page 120, of the vehicle.
Use coasting conditions When approaching a red light, take your foot
off the accelerator and let the vehicle coast to
a halt.
For going downhill take your foot off the accel‐
erator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
Switch off the engine during longer stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Auto Start/Stop function The Auto Start/Stop function of your vehicle
automatically switches off the engine during a
stop.
If the engine is switched off and then restarted
rather than leaving the engine running con‐
stantly, fuel consumption and emissions are
reduced. Savings can begin within a few sec‐
onds of switching off the engine.
In addition, fuel consumption is also deter‐
mined by other factors, such as driving style,
road conditions, maintenance or environmental
factors.
Switch off any functions that
are not currently needed
Functions such as seat heating and the rear
window defroster require a lot of energy andreduce the range, especially in city and stop-
and-go traffic.
Switch off these functions if they are not
needed.
The ECO PRO driving program supports the
energy conserving use of comfort features.
These functions are automatically deactivated
partially or completely.
Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle efficiency and service life.
BMW recommends that maintenance work be
performed by a BMW dealer’s service center.
For information on the BMW Maintenance
System, refer to page 279.
ECO PRO
The concept
ECO PRO supports a driving style that saves
on fuel consumption. For this purpose, the en‐
gine control and comfort features, e. g. the cli‐
mate control output, are adjusted.
Under certain conditions the engine is auto‐
matically decoupled from the transmission in
the D selector lever position. The vehicle con‐
tinues traveling with the engine idling to re‐
duce fuel consumption. Selector lever position
D remains engaged.
In addition, context-sensitive instructions are
displayed to assist with an optimized fuel con‐
sumption driving style.
The achieved extended range is displayed in
the instrument cluster as bonus range.

Route-ahead assistant
The concept The system helps to conserve fuel and pro‐
motes a proactively driving style. It can detect
certain upcoming sections of the journey
based on the navigation data and alert the
driver to them in good time.
The detected route sections, such as built-up areas or changes of road require the driver to
reduce speed.
General information
This alert is issued even if the upcoming route
section cannot yet be detected while driving.
The alert is displayed until the route section is
reached.
If an alert is received, the vehicle's speed and
its fuel consumption can be reduced by back‐
ing off the accelerator and coasting until the
route section is reached.
Depending on the situation, the system also
uses the engine brake automatically with a
pausing of the coast, refer to page 245, func‐
tion.
Functional requirements
This function is available in ECO PRO mode.
The system depends on the timeliness and
quality of the navigation data.
The navigation data can be updated.

Coasting
The concept The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐
sion when selector lever position D is set. The
vehicle continues traveling with the engine idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coast‐
ing.
As soon as you step on the brake or accelera‐
tor pedal, the engine is automatically coupled
again.
Information Coasting is a component of the ECO PRO, re‐
fer to page 241, driving mode.
Coasting is automatically activated when ECO
PRO mode is called via the Driving Dynamics
Control.
