Socket for Onboard
Diagnosis OBD
On the driver's side is an OBD socket for 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 certain 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 comes on if the gas
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. Make sure that the gas cap is
correctly 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 extract 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
232
Carpet/floor mats*
The floor mats can be removed for cleaning.
When heavily soiled, clean carpets with a
microfiber cloth and water or textile cleaner.
Rub back and forth in the direction of travel; oth-
erwise, the carpet may become matted.
Interior plastic parts
>Imitation leather surfaces
>Lamp glasses
>Display pane of instrument cluster
>Matte parts
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 chemically, as this may
destroy the webbing.<
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 displays, e.g. of the radio or instrument
cluster, use a cleaning cloth for displays 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
damage 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.

Replacing components
234 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. When the
light is switched on, the condensation will dis-
appear after a short time. The headlight lenses
do not need to be replaced.
At high humidities, e.g. water droplets may form
in the lights; have these checked by your BMW
center.,
Xenon lamps
These bulbs have a very long 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 care, provided that local
legislation does not prohibit this.
Have any work on the xenon lamp system,
including bulb replacements, performed
only by a BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. Otherwise, if
such work is carried out improperly, the high
voltage in the system presents the danger of
fatal injuries.<
Access to the lamps
1.Switch off the lamps and take the remote
control out of the ignition lock.
2.Remove the upper cover from the head-
lamp. To do so, use a screwdriver to press
the catches towards the rear, see arrows,

tach the cover.
Be careful when installing the cover; oth-
erwise, leaks could occur and cause dam-
age to the headlamp system.<

Changing wheels
Your BMW is equipped with run-flat tires as
standard. This eliminates the need to change a
wheel immediately in the event of a puncture.
For information on continuing to drive with a
damaged tire, refer to Indication of a flat tire on
page93.
The symbol identifying run-flat tires is a circle
with the letters RSC on the sidewall, refer to
Run-flat tires, page220.
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount run-flat tires for your own safety. In the
event of a flat, no spare wheel is available. Your
BMW center will be glad to advise you. Refer
also to New wheels and tires, page220.
The tools for changing wheels are avail-
able as optional accessories from your
BMW center.<

Being towed
Make sure that the ignition is switched on,
refer to page55; otherwise, the low-beam
headlamps, tail lamps, turn signal indicators and
windshield wipers may be unavailable.
Power steering assistance is not available when
the engine is not running. Thus, braking and
steering will require increased effort. Active
steering is not active and it will be necessary to
turn the steering wheel further.<
Manual transmission
Gearshift lever in neutral position.
Automatic transmission
Selector lever in position N.
Changing selector lever positions, refer to
page58.
Do not exceed a towing speed of 45 mph
or 70 km/h and a towing distance of
90 miles/150 km; otherwise, the automatic
transmission may be damaged.<

Giving and receiving assistance
242
Sports automatic transmission with
double clutch
Make sure that the parking lock P is not
engaged; otherwise, the rear wheels are
immobilized.
When using the car wash function, refer to
page230, make sure that after approx.
30 minutes, the parking lock P is automatically
engaged and thus immobilizes the rear wheels.
In the event of an electrical malfunction or if the
vehicle must be towed for more than approx.
20 minutes, unlock the parking lock manually,
refer to page63.<
When towing, do not exceed a maximum
speed of 30 mph or 50 km/h and a maxi-
mum distance traveled of 30 miles/50 km; oth-
erwise, the transmission may be damaged.<
BMW recommends transporting the vehicle on
a tow truck with a flatbed or towing with the rear
axle raised.
Towing methods
Do not lift the vehicle by a tow fitting or
body and chassis parts; otherwise, dam-
age may result.<
With a tow bar
The towing vehicle must not be lighter
than the towed vehicle; otherwise, it may
be impossible to maintain control.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an angle,
please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.
Attach the tow bar to the tow fittings only,
as attaching it to other parts of the vehicle
could result in damage.<
With a tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Attach the tow rope to the tow fittings only, as
attaching it to other parts of the vehicle could
result in damage.<
