Socket for Onboard
Diagnosis OBD
Primary components that make up exhaust
emissions can be checked by a device via the
OBD socket.
This socket is located under a cover on the left
on the driver's side.
Exhaust emission values
The warning lamp lights up:
The vehicle emissions are raised. The
trip can be continued. Have the car
checked as soon as possible.
Canadian models display this warn-
ing lamp.
The lamp flashes under certain condi-
tions. 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 comes on if the gas
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. If the gas cap is then tightened, the
warning lamp should go out within a few days.
Data recorders
Your vehicle may be equipped with one or sev-
eral measuring or diagnostic modules or a
device for recording or sending certain vehicle
data or information. In addition, if you have
signed a service contract for BMW Assist, cer-
tain vehicle data may be transmitted or
recorded in order to facilitate the corresponding
services.

Care
Care products
Regular cleaning and care contributes signifi-
cantly to the value retention 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
damage.<
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 and 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 brake discs can corrode.<
Automatic car washes
Preference should be given to cloth car washes.
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 page227.
>If necessary: fold in the exterior mirrors,
refer to page45.
>Maximum permissible tire width.
Avoid car washes with guide rail heights
over 4 in/10 cm; otherwise, there is dan-
ger of damaging chassis parts.<
Preparations before driving into an automatic
car wash:
>Unscrew the rod antenna
*.
>Deactivate the rain sensor
* to avoid unin-
tentional activation of the wipers.
>Remove additional attachments, e.g., spoil-
ers or telephone antennas, if there is a pos-
sibility that they could be damaged.
Automatic transmission
Before driving into an automatic car wash, per-
form the following steps to ensure that the vehi-
cle can roll:
1.Insert the remote control, even with Com-
fort Access, into the ignition lock.
2.Move the selector lever to position N.
3.Release the parking brake.
4.Switch off the engine.
5.Leave the remote control in the ignition lock
so that the vehicle can roll.

Steam jets / high-pressure washers
When using steam jets or high-pressure
washers, ensure that you maintain suffi-
cient clearance to the vehicle and do not exceed
a temperature of 1407/606.
Insufficient clearance or excessive pressure or
temperature can lead to component damage or
water penetration. Follow the operating instruc-
tions of the high-pressure washer.<
When using high-pressure washers, do
not spray against the seals of the retract-
able hardtop, the sensors and the cameras, e.g.,
of the Park Distance Control or Rear View Cam-
era, for an extended period and maintain a dis-
tance of at least 12 in/30 cm.<
Manual car wash
When washing the vehicle by hand, use large
quantities of water and car shampoo if neces-
sary. Clean the vehicle with a sponge or wash-
ing brush, applying light pressure only.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unintentional activation of the
wipers.<
Observe local regulations pertaining to
washing vehicles by hand.<
Headlamps
Do not rub them dry and do not use abrasive or
corrosive cleaning agents.
Loosen dirt, e.g., insects, with shampoo or
insect remover and wash away with copious
quantities of water.
Thaw ice with a windshield deicer and do not
use an ice scraper.
Windows
Clean the inside and outside surfaces of the
windows and the mirrors with window cleaner.
Do not clean the mirrors with cleaners
containing quartz.<
Retractable hardtop
Proceed as you would in a normal car wash.
When you open a wet hardtop, water
drops may run into the cargo area. If nec-
essary, remove items from the cargo area
beforehand to avoid water stains or soiling.<
Paintwork care
Regular care contributes to value retention and
protects the paintwork against the long-term
effects of damaging substances.
Region-specific environmental influences can
damage the vehicle paintwork. Therefore, it is
important to adapt the frequency and scope of
car care accordingly.
Immediately remove aggressive materials such
as spilled fuel, oil, grease, brake fluid, tree sap
or bird droppings to prevent damage to the
paintwork.
Repairing paintwork damage
Immediately repair scratches or similar
damage, such as that caused by stones
hitting the vehicle, where necessary to prevent
rusting.<
BMW recommends having paintwork damage
repaired by a professional paint repair work-
shop according to BMW specifications using
original BMW paint materials.

Care
210
Preservation
A preservation treatment is necessary when
water no longer beads off the clean paintwork
surface. Only use products for paintwork pres-
ervation that contain carnauba or synthetic
waxes.
Rubber seals
Treat only with water or rubber care products.
Do not use silicon-containing care prod-
ucts on rubber seals; otherwise, noise
and damage could occur.<
Chrome parts
Carefully clean vehicle parts, such as the radia-
tor grill, door handles or window frames, with
copious quantities of water and a shampoo
additive. For additional treatment, use a chrome
polish.
Light-alloy wheels
For technical reasons, dust is generated during
braking that is deposited on the light-alloy
wheels. Remove the dust regularly using acid-
free rim cleaner.
Do not use aggressive, acidic, strongly
alkaline and abrasive cleaning agents or
steam jets over 1407/606; otherwise, dam-
age may occur.<
Outside sensors / cameras
Keep the sensors and cameras on the
outside of the vehicle, e.g., those of Park
Distance Control, clean and free of ice to ensure
that they remain fully functional.<
Interior care
Upholstery fabrics/cloth trims/
Alcantara fabrics
Vacuum regularly with a vacuum cleaner to
remove superficial dirt.
To remove severe spots such as stains from
beverages, use a soft sponge or lint-free
microfiber cloth and suitable interior cleaners.
Follow the instructions on the packaging.Clean the upholstery down to the seams
using a sweeping motion. Avoid strong
rubbing.<
Opened Velcro fasteners, etc., on pants
or other articles of clothing can damage
the seat covers. Ensure that Velcro fasteners
are closed.<
Leather/leather trim
The leather used by BMW is a high quality
natural product. Slight irregularities in the
leather are a typical characteristic of natural
leather.<
Dust and road grit in the pores and folds of the
leather have an abrasive effect, leading to
increased wear and causing the leather surface
to become brittle prematurely. Therefore, regu-
larly dust the leather with a cloth, for example.
Clean light-colored leather more frequently as
dust and dirt are more noticeable.
Treat the leather at least once every two
months using a leather lotion as dirt and grease
will gradually attack the leather's protective
layer.
Rivets, etc., on pants or other articles of
clothing can damage the seat covers.<
Carpets / cargo area
You can vacuum the carpets and floor mats or
clean them with interior cleaner if heavily soiled.
The floor mats can be removed for cleaning.
When replacing the mats, ensure that the seat
rails do not extend over the floor mats, as this
may damage the mats.
Lint on the floor mats occurs for technical rea-
sons and can be removed by vacuuming
repeatedly.
When cleaning the interior, do not move
both seats all the way forward while mov-
ing them to their uppermost position and lean-
ing the backrests forward. Otherwise, the seats
could hit and damage the seal on the wind-
shield, the sun visor or the headliner.<

Clean with water and solvent-free plastic
cleaner if necessary.
Fine wood parts
Clean fine wood trim and fine wood parts with a
damp cloth. Wipe dry with a soft cloth.
Safety belts
Dirty belt straps impede the reeling action and
thus have a negative impact on safety.
Do not clean with cleaning agents as
these may destroy the fabric.<
Use only a mild soapy solution, with the safety
belts clipped into their buckles. Do not allow the
reels to retract the safety belts until they are dry.
Interior sensors / cameras
To clean interior sensors and cameras, e.g., of
the high-beam assistant, use a lint-free cloth
moistened with glass cleaner.
Displays
To clean the displays, e.g., of the radio or instru-
ment cluster, use a display cleaning cloth or a
soft, non-abrasive, lint-free cloth.
Avoid applying excessive pressure when
cleaning the displays; otherwise, damage
may occur.<
Do not use chemical or abrasive house-
hold cleaning agents. Keep all types of
fluid away from the device. Otherwise, surfaces
or electrical components may be corroded or
damaged.<
CD/DVD drives
Do not use a cleaning CD, as it may dam-
age parts of the drive.<
Vehicle storage
If your vehicle is to be decommissioned for
longer than three months, your BMW center or
a workshop that operates according to BMW
specifications will be glad to advise you.

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.<
You can obtain a selection of replacement bulbs
at your BMW center.
Only change bulbs while they are cool to
the touch; otherwise, you could suffer
burns.<
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 headlamps, please follow the
instructions in the chapter entitled "Care"'.
If the routine for changing a particular
bulb is not described here, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
Light-emitting diodes LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays 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 to the retina.<
