Vehicle equipment
In this chapter, all pr oduction, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.
BMW Maintenance System
The BMW maintenance system advises you of
necessary maintenance measures and helps
you maintain the traffic and operating safety of
the vehicle.
Condition Based Service CBS
Sensors and special algo rithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirem ents, the system builds
the basis for trouble-free driving.
On the Control Display, you can have the
remaining times or distances for selected main-
tenance tasks and any le gally prescribed dates
displayed, refer to page 87: >
Engine oil
> Brake pads: separately for front and rear
> Brake fluid
> Vehicle check
> Legally mandated in spections depending
on local regulations
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control
while you are driving. Your dealership Service
Advisor can read out this data from the remote
control unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore give your
dealership Service Advisor the remote control
unit that you last used.
Make sure that the da te is always set cor-
rectly, refer to page 91; otherwise, the
effectiveness of Condition Based Service CBS
is not assured. <

Please consult your Serv ice and Warranty Infor-
mation Booklet for US models and Warranty
and Service Guide Booklet for Canadian models
for additional information on service require-
ments.
BMW recommends that you have service
and repair operations performed at your
BMW center.
Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
cle's Service and Warranty Information Booklet
for US models and Warranty and Service Guide
Booklet for Canadian models. These entries
verify that your vehicle has received the speci-
fied regular maintenance. <

Diagnosis OBD
On the drive r's side is a n OBD so cket f or check-
ing components relevant to the composition of
the vehicle's emissions.
Emissions
The warning lamp lights up:
The vehicle is producing higher emis-
sions. The trip can be continued. Have
the car checked as soon as possible.
Canadian models display this warning
lamp.
The lamp flashes under ce rtain conditions. This
indicates excessive misfiring in the engine. If
this happens, you should reduce your speed
and visit your nearest BMW center as soon as
possible. Severe engine misfiring can quickly
lead to serious damage of emissions-related
components, especially the catalytic converter.
The warning lamp lights up if the fuel
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. Make sure that the fuel cap is cor-
rectly positioned and close it until it audibly
clicks.
Data memory
Your vehicle records data about the operation,
faults, and user settings. These data are stored
in the vehicle and in extr act form, in the remote
control, and can be read out using suitable
devices at your BMW center. The data that are
read out are used to support service proce-
dures and repairs or to optimize and expand
vehicle functions. If you have a BMW Assist
contract, certain vehicle data can also be trans-
mitted directly from the vehicle in order to
enable the desired services.

Care products
Regular cleaning and care contributes signifi-
cantly to the value re tention of your BMW.
BMW recommends cleaning and caring for your
vehicle with products that are approved by
BMW for this purpose.
Your BMW center will be happy to advise you on
the products and services available for cleaning
and caring for your BMW.
Original BMW CareProducts have been
material-tested, laboratory-checked and
proven in the field, and offer optimal care and
protection for your vehicle. <
Do not use cleaners that contain alcohol
or solvents as these may result in dam-
age.<
Cleaning agents can contain substances
that are dangerous or hazardous to your
health. Therefore, follow the warning and safety
instructions on the packaging. When cleaning
inside the vehicle, always open the doors or
windows of the vehicle. In enclosed areas, pro-
vide for sufficient ventilation. Only use products
designed for cleaning vehicles. <
Exterior care
Washing the vehicle
Especially during the winter months,
ensure that the vehicle is washed more
frequently. Heavy soiling an d road salt can lead
to vehicle damage. <
After washing the vehicle, apply the
brakes briefly to dry them; otherwise,
water can reduce braking efficiency over the
short term and the brake discs can corrode. <
Automatic car washes
Give preference to car washes that use cloth or
soft brushes in order to avoid paint damage.
Do not use high-pressure car washes;
otherwise, water may drip into the vehicle
around the windows. <
Before driving into a car wash, ensure that it is
suitable for your BMW. Check the following:
> Dimensions of your vehicle, refer to
page 285.
> If necessary: fold in the exterior mirrors,
refer to page 55.
> Maximum permissible tire width.
Avoid car washes with guide rail heights
over 4 in/10 cm; otherwise, there is the
danger of damaging chassis parts. <
Preparations before driv ing into an automatic
car wash:
> Unscrew the rod antenna.
> Deactivate the rain sensor to prevent
undesired wiper operation.
> Remove additional add-on parts, e.g. spoil-
ers or phone antennas, if they could be
damaged.
> Leave the remote control in the ignition
lock.

Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. They should, therefore,
be handled carefully. BMW recommends hav-
ing your BMW center perform any work that you
do not feel competent to perform yourself or
that is not described here.
Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean tissue, cloth or something similar, or hold
the bulb by its base. <
Replacement bulb sets are available at your
BMW center. Only change bulbs while they are cool to
the touch; otherwise, you could suffer
burns. <

Replacing components
Mobility
When working on electrical systems,
always begin by switching off the con-
sumer in question; otherwise, short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer. <
For care of the headla mps, please follow the
instructions in the ch apter entitled 'Care'.
To replace lamps not described here,
please contact your BMW center. <
Light-emitting diodes LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls, displays, and equipment in your
vehicle. These light-emitting diodes, which
operate using a concept similar to that applied
in conventional lasers, are officially designated
as Class 1 light-emitting diodes.
Do not remove the covers or expose the
eyes directly to the unfiltered light source
for several hours; otherwise, this could cause
irritation of the retina. <
Headlight lenses
In cool or humid weather, condensation may
form on the interior of outside lamps. The con-
densation will disappear after a short time when
driving with the headlamps switched on. The
headlamp glasses do not need to be changed.
If the headlamps do not defrost despite driving
with the headlamps switch ed on, and additional
moisture builds up, for example water droplets
in the lamps, have them checked by your BMW
center.
Xenon lamps
These bulbs have a very lo ng service life and are
highly unlikely to fail. If a xenon lamp fails never-
theless, switch on the fog lamps and continue
the journey with great ca re, provided that local
legislation does not prohibit this. Have all work on the xenon lamp system,
including bulb replacements, performed
only by your BMW center . Due to high voltage,
there is a risk of fatal injury if work on the xenon
lamps is carried out improperly. <
Access to the lamps
1.Switch off the lamps and take the remote
control out of the ignition lock.
2. Remove the upper co ver from the head-
lamp. To do so, use a screwdriver to press
the catches towards th e rear, see arrows,
and pull the cover forward and out.
Follow the same steps in reverse order to reat-
tach the cover. Be careful when inst alling the cover; oth-
erwise, leaks could occur and cause dam-
age to the headlamp system.<
Parking lamps and roadside parking
lamps, daytime running lights
These lamps use LED technology for operation.
If they malfunction, please contact your BMW
center.
Corner-illuminating lamps
