ing to BMW repair procedures with appropri‐
ately trained personnel.
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards.
Parts and accessories
For your own safety, use genuine parts and ac‐
cessories approved by BMW. When you pur‐
chase accessories tested and approved by
BMW and Genuine BMW Parts, you simultane‐
ously acquire the assurance that they have been
thoroughly tested by BMW to ensure optimum
performance when installed on your vehicle.
BMW warrants these parts to be free from de‐
fects in material and workmanship. BMW will not
accept any liability for damage resulting from in‐
stallation of parts and accessories not approved
by BMW. BMW cannot test every product made
by other manufacturers to verify if it can be used
on a BMW safely and without risk to either the
vehicle, its operation, or its occupants. Genuine
BMW Parts, BMW Accessories and other prod‐
ucts approved by BMW, together with profes‐
sional advice on using these items, are available
from all BMW centers. Installation and operation
of non-BMW approved accessories such as
alarms, radios, amplifiers, radar detectors,
wheels, suspension components, brake dust
shields, telephones, including operation of any
mobile phone from within the vehicle without
using an externally mounted antenna, or trans‐
ceiver equipment, for instance, CBs, walkie-
talkies, ham radios or similar accessories, may
cause extensive damage to the vehicle, com‐
promise its safety, interfere with the vehicle's
electrical system or affect the validity of the
BMW Limited Warranty. See your BMW center
for additional information. Maintenance, re‐
placement, or repair of the emission control de‐
vices and systems may be performed by any au‐
tomotive repair establishment or individual
using any certified automotive part.California Proposition 65 Warning
California laws require us to state the following
warning:
Engine exhaust and a wide variety of automobile
components and parts, including components
found in the interior furnishings in a vehicle, con‐
tain or emit chemicals known to the State of Cal‐
ifornia to cause cancer and birth defects and re‐
productive harm. In addition, certain fluids
contained in vehicles and certain products of
component wear contain or emit chemicals
known to the State of California to cause cancer
and birth defects or other reproductive harm.
Battery posts, terminals and related accessories
contain lead and lead compounds. Wash your
hands after handling. Used engine oil contains
chemicals that have caused cancer in laboratory
animals. Always protect your skin by washing
thoroughly with soap and water.

Check Control
The concept
The Check Control monitors vehicle functions
and alerts you to any malfunctions in the sys‐
tems monitored.
Such Check Control messages involve indicator
or warning lamps in the instrument cluster and,
in some circumstances, an acoustic signal.Indicator/warning lamps
The indicator and warning lamps can light up in
a variety of combinations and colors.

Ensure that the floor mats are securely fastened
again when they are returned after being re‐
moved, such as for cleaning.◀
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.
Downshifting in manual mode of the 8-gear
Sport automatic transmission, refer to page 54.
Downshifting in manual mode of the 7-gear
Sport automatic transmission with dual clutch,
refer to page 57.
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
Never drive with the transmission in neu‐
tral, with the engine switched off or with the
clutch depressed; otherwise, you will have nei‐
ther the braking action of the engine or nor its
power assistance when braking or steering.◀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.
Loading Overloading the vehicle
To avoid exceeding the approved carrying
capacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden loss
of tire inflation pressure.◀
Secure heavy objects
Never transport unsecured heavy or hard
objects in the passenger compartment, as they
could be thrown around and pose a safety haz‐
ard to the vehicle's occupants during abrupt
braking or evasive maneuvers.◀
No fluids in the cargo area
Make sure that fluids do not leak into the
cargo area; otherwise, the vehicle may be dam‐
aged.◀

MaintenanceVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.
BMW Maintenance System
The maintenance system provides information
on required maintenance measures and thus
provides support in maintaining road safety and
the operational reliability of the vehicle.
Condition Based Service CBS
Sensors and special algorithms take into ac‐
count the driving conditions of your vehicle.
Based on this, Condition Based Service deter‐
mines the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance you need to your user
profile.
Details on the service requirements, refer to
page 65, can be displayed on the instrument
cluster.
Service data in the remote control
Information on the required maintenance is con‐
tinuously stored in the remote control. Your
service center will read out this data and suggest
the right array of service procedures for your ve‐
hicle.
Therefore, hand your service specialist the re‐
mote control that you used 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 necessary,
changing the engine oil and the microfilter/acti‐
vated-charcoal filter.
