service BMW 320i SEDAN 2016 Service Manual

You can obtain a selection of replacement
bulbs at the service center.
Danger of burns
Only change bulbs when they are cool;
otherwise, there is a danger of getting
burned.◀
Working on the lighting system
When working on the lighting system,
you should always reel off the lights affected to
prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.◀
Do not perform work/bulb replacement
on xenon headlights
Have any work on the xenon lighting system,
including bulb replacement, performed only by
a service center. Due to the high voltage
present in the system, there is a danger of fatal
injuries if work is carried out improperly.◀
Do not touch the bulbs
Do not touch the glass of new bulbs with
your bare hands, 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.◀
Light-emitting diodes (LEDs)
Some items of equipment use light-emitting
diodes installed behind a cover as a light
source.
These light-emitting diodes, which are related
to conventional lasers, are officially designated as Class 1 light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never
stare into the unfiltered light for several hours;
otherwise, irritation of the retina could result.◀Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the light switched on, the conden‐
sation evaporates after a short time. The head‐
light glass does not need to be changed.
If the headlights do not dim despite driving
with the light switched on, increasing humidity
forms, e. g. water droplets in the light, have the service center check this.
Headlight setting The headlight adjustments can be affected by
changing lights and bulbs. Have the head‐
lights' settings checked and corrected by serv‐
ice after a replacement.

Because of the long life of these bulbs, the
likelihood of failure is very low. Switching the
lights on and off frequently shortens their life.
If a bulb fails, reel on the front fog lights and
continue the trip with great care. Comply with
local regulations.
Do not perform work/bulb replacement

Battery replacementUse approved vehicle batteries only
Only use vehicle batteries that have been
approved for your vehicle by the manufacturer;
otherwise, the vehicle could be damaged and
systems or functions may not be fully availa‐
ble.◀
After a battery replacement, have the battery registered on the vehicle by the service center
to ensure that all comfort features are fully
available and that any Check Control mes‐
sages of these comfort features are no longer
displayed.
Charging the battery

ciently charged to guarantee that the battery
remains usable for its full service life.
The battery may need to be charged in the fol‐
lowing cases:▷When making frequent short-distance
drives.▷If the vehicle is not used for prolonged pe‐
riods, longer than a month.
Hints
Do not connect charging devices to the
12 volt socket in the vehicle

Response Center which serve to deter‐
mine the necessary rescue measures. E. g.
the current position of the vehicle, if it can
be established.▷If the LED is flashing green, but the BMW
Response Center can no longer be heard
via the speaker, you can nevertheless still
be heard at the BMW Response Center.

mediately to prevent the finish from being al‐
tered or discolored.
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

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.

grease removers, fuel, or such; this could lead
to surface damage.◀
Safety belts
Dirty belt straps impede the reeling action and
thus have a negative impact on safety.
Chemical cleaning
Do not clean chemically; this can destroy
the webbing.◀
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.
Carpets and floor mats 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.

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.◀
Floor mats can be removed from the car's inte‐
rior for cleaning.
If the floor carpets are very dirty, clean with a
microfiber cloth and water or a textile cleaner.
To prevent matting of the carpet, rub back and
forth in the direction of travel only.
Sensor/camera lenses
To clean sensors and camera lenses, use a
cloth moistened with a small amount of glass
detergent.Displays/monitors
Cleaning displays and screens
Do not use any chemical or household
cleaning agents; otherwise, surfaces can be af‐
fected.◀
Keeping out moisture
