General driving notes
Closing the trunk lid Drive with the trunk lid closed
Only drive with the tailgate closed; other‐
wise, in the event of an accident or braking and
evasive maneuvers, passengers and other traf‐
fic may be injured, and the vehicle may be
damaged. In addition, exhaust fumes may en‐
ter the vehicle interior.◀
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.
Hot exhaust system
Hot exhaust system
High temperatures are generated in the
exhaust system.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that flammable materials, e. g. hay, leaves,
grass, etc. do not come in contact with the hot
exhaust system while driving, while in idle po‐
sition mode, or when parked. Such contact
could lead to a fire, resulting in an increased
risk of serious personal injury as well as prop‐
erty damage.
Do not touch hot exhaust pipes; otherwise,
there is a danger of getting burned.◀
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is not recommended to use mobile phones,
such as mobile phones, in the vehicle interior
without a direct connection to an external aer‐
ial. Otherwise, the vehicle's electronics and
mobile communication devices can interfere
with each other. In addition, there is no assur‐
ance that the radiation generated during trans‐
mission will be conducted away from the vehi‐
cle interior.◀
Hydroplaning Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent 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 Observe water level and speed
Do not exceed the maximum water level
and maximum speed; otherwise, the vehicle's
engine, the electrical systems and the trans‐
mission may be damaged.◀
Drive though 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.
The pulsing of the brake pedal indicates 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.Seite 157Things to remember when drivingDriving tips157

Objects within the range of movement
of the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the pedal area; otherwise, the
function of the pedals could be impeded while
driving and create the risk of an accident.
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 attached to
floor.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, e.g.◀
Driving in wet conditions When 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 Avoid stressing the brakes
Avoid placing excessive stress on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brakes
wearing out and possibly 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 are un‐
available with the engine stopped.◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐wise the brakes may overheat and reduce
brake efficiency.
Manual transmission:
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.
M double-clutch transmission:
You can increase the engine's braking effect
by shifting down in sequential mode, refer to
page 71.
Brake disc corrosion
Brake disc corrosion and contamination of the
brake pads are favored by:▷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.
Ground clearance Limited ground clearance
Observe the limited ground clearance of
the vehicle, e. g. while entering underground
parking garages or when driving over obsta‐
cles. Otherwise, damages to the vehicle may
result.◀

MaintenanceVehicle 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.
BMW maintenance system The maintenance system indicates required
maintenance measures, and thereby provides
support in maintaining road safety and the op‐
erational reliability of the vehicle.
In some cases scopes and intervals may vary
according to the country-specific version. Re‐
placement work, spare parts, fuels and lubri‐
cants and wear materials are calculated sepa‐
rately. Additional information is available from
the service center.
Condition Based Service
CBS
Sensors and special algorithms take into ac‐
count the driving conditions of your vehicle.
Based on this, Condition Based Service recog‐
nizes the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance corresponding to your
user profile.
Detailed information on service requirements,
refer to page 83, can be displayed on the Con‐
trol Display.Service data in the remote control
Information on the required maintenance is
continuously stored in the remote control. Your service center will read out this data and
suggest the right array of service procedures for your vehicle.
Therefore, hand your service specialist the re‐
mote control with which the vehicle was driven
most recently.
Storage periods Storage periods during which the vehicle bat‐
tery was disconnected are not taken into ac‐
count.
If this occurs, have a service center update the
time-dependent maintenance procedures,
such as checking brake fluid and, if needed,
changing the engine oil and the microfilter/
activated-charcoal filter.

can be reduced and corrosion of the brake
discs can occur.
Completely remove all residues on the win‐
dows, to minimize loss of visibility due to
smearing and to reduce wiper noises and
wiper blade wear.
Vehicle care
Car care products BMW recommends using care and cleaning
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
dangerous and harmful to your health.◀
Vehicle paint
Regular care contributes to driving safety and
value retention. Environmental influences in
areas with elevated air pollution or natural con‐
taminants, such as tree resin or pollen can af‐
fect the vehicle's paintwork. Tailor the fre‐
quency and extent of your car care to these
influences.
Aggressive substances such as spilled fuel, oil,
grease or bird droppings, must be removed im‐
mediately to prevent the finish from being al‐
tered or discolored.
Only use respectively approved cleaning and
care products for vehicles with matte finish.
Seite 206MobilityCare206
Online Edition for Part no. 01 40 2 960 786 - II/15

Suitable care products for matte finishes are
available from the service center.
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 upholstery is very dirty, e.g., with 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
material vigorously.
Damage from Velcro® fasteners
Open Velcro® fasteners on pants or
other articles of clothing can damage the seat
covers. Ensure that any Velcro® fasteners are
closed.◀
Caring for special components
Light-alloy wheels
When cleaning the vehicle, use only neutral
wheel cleaners having a pH value from 5 to 9.
Do not use abrasive cleaning agents or steamjets above 140 ℉/60 ℃. Follow the manufac‐
turer's instructions.
Aggressive, acidic or alkaline cleaning agents
can destroy the protective layer of adjacent
components, such as the brake disk.
Chrome surfaces
Carefully clean components such as the radia‐
tor grille or door handles with an ample supply
of water, possibly with shampoo added, partic‐
ularly when they have been exposed to road
salt.
Rubber components Aside from water, treat only with rubber
cleansers.
When cleaning rubber seals, do not use any
silicon-containing car care products in order to
avoid damage or noises.
Fine wood partsClean fine wood facing and fine wood compo‐
nents only with a moist rag. Then dry with a
soft cloth.
Plastic components
These include:▷Imitation leather surfaces.▷Roofliner.▷Lamp lenses.▷Instrument cluster cover.▷Matt black spray-coated components.▷Painted parts in the interior.
Clean with a microfiber cloth.
Dampen cloth lightly with water.
Do not soak the roofliner.
No cleansers that contain alcohol or sol‐
vents
Do not use cleansers that contain alcohol or
solvents, such as lacquer thinners, heavy-duty
