ECU BMW 320i SEDAN 2015 Owner's Guide

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
General information Make sure that the battery is always suffi‐
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
Do not connect battery chargers to the fac‐
tory-installed 12 volt sockets in the vehicle as
this may damage the vehicle battery due to an
increased power consumption.◀
Starting aid terminals
In the vehicle, only charge the battery via the
starting aid terminals, refer to page 225, in the
engine compartment with the engine off.
Power failure
After a temporary power loss, some equipment
needs to be newly initialized or individual set‐
tings updated, e. g.:▷Seat and mirror memory: store the posi‐
tions again.▷Time: update.▷Date: update.▷Glass sunroof and sliding visor: initialize
the system, refer to page 48.
Disposing of old batteries
Have old batteries disposed of by your
service center or bring them to a recy‐
cling center.
Maintain the battery in an upright position for
transport and storage. Secure the battery so
that it does not tip over during transport.
Fuses Hints Replacing fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a substi‐
tute of another color or amperage rating; this
could lead to a circuit overload, ultimately re‐
sulting in a fire in the vehicle.◀
Plastic tweezers and information on the fuse
types and locations are stored in the fuse box
in the trunk.

Steptronic transmission: transporting
your vehicle
Note Your vehicle is not permitted to be towed.
Therefore, contact a service center in the
event of a breakdown.
Do not have the vehicle towed
Have your vehicle transported on a load‐
ing platform only; otherwise, damage may oc‐
cur.◀
Tow truck
The vehicle should only be transported on a
loading platform.
Do not lift the vehicle
Do not lift the vehicle by the tow fitting or
body and chassis parts; otherwise, damage
may result.◀
Use tow fitting located in the front only for po‐
sitioning the vehicle.
Towing other vehicles
Hints Light towing vehicle
The towing vehicle must not be lighter
than the vehicle being towed; otherwise, it will
not be possible to control the vehicle's re‐
sponse.◀
Attaching the tow bar/tow rope correctly
Attach the tow bar or tow rope to the tow
fitting; connecting it to other vehicle parts may
cause damage.◀▷Switch on the hazard warning system, de‐
pending on local regulations.▷If the electrical system has failed, clearly
identify the vehicle being towed by placing
a sign or a warning triangle in the rear win‐
dow.
Tow bar
The tow fittings used should be on the same
side on both vehicles.
Should it prove impossible to avoid mounting
the tow bar at an offset angle, please observe
the following:
▷Maneuvering capability is limited going
around corners.▷The tow bar will generate lateral forces if it
is secured with an offset.
Tow rope
When starting to tow the vehicle, make sure
that the tow rope is taut.
To avoid jerking and the associated stresses
on the vehicle components when towing, al‐
ways use nylon ropes or nylon straps.
Tow fitting
The screw-in tow fitting should always be car‐
ried in the vehicle.
The tow fitting can be screwed in at the front
or rear of the BMW.

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.

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.

Keep floor mats, carpets, and any other
objects out of the pedal area; otherwise, the
function of the pedals could be impeded while

Do not place additional floor mats over existing
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
Keep all fluids and moisture away from
the unit; otherwise, electrical components can
be damaged.◀

Avoid pressing too hard when cleaning
and do not use abrasive materials; otherwise,
