2012 BMW 335I SEDAN check engine

Socket for OBD Onboard
Diagnosis
Position
There is an OBD socket on the driver's side for
checking the primary components in the vehicle
emissions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as pos‐
sible.
Canadian model: warning light indi‐
cates the engine symbol.▷The warning lamp flashes under certain cir‐
cumstances:
This indicates that there is excessive misfir‐
ing in the engine.
Reduce the vehicle speed and have the sys‐
tem checked immediately; otherwise, seri‐
ous engine misfiring within a brief period can
seriously damage emission control compo‐
nents, in particular the catalytic converter.
Fuel cap
The indicator lamp lights up.
If the fuel cap is not properly tightened,
the OBD system may conclude that fuel
vapor is escaping. If the cap is then tightened,
the display should go out in a short time.
Data memory
Your vehicle records data relating to vehicle op‐
eration, faults and user settings. These data are
stored in the remote control and can be read out
with suitable devices, particularly when the ve‐
hicle is serviced. The data obtained in this way
provide valuable information for service proc‐
esses and repair or for optimizing and develop‐
ing vehicle functions further.
In addition, if you signed a service contract for
BMW Assist, certain vehicle data can be sent
directly from the vehicle to facilitate the desired
services.Seite 278MobilityMaintenance278

to ensure that all comfort functions are fully
available and that any Check Control messages
are no longer displayed.
Charging the battery
In the vehicle, only charge the battery via the
starting aid terminals, refer to page 292, in the
engine compartment with the engine off.
Power failure
After a temporary power loss, some equipment
needs to be reinitialized.
Individual settings need to be reprogrammed:▷Seat and mirror memory: store the positions
again.▷Time: update.▷Date: update.▷Radio station: save again.▷Navigation system: wait for the operability of
the navigation.
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
Notes Replacing fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a substitute
of another color or amperage rating; this could
lead to a circuit overload, ultimately resulting in
a fire in the vehicle.◀
Plastic tweezers and information on the fuse
types and locations are stored in the fuse box in
the cargo area.

Assist Response Center contacts you and
takes further steps to help you.
Even if you are unable to respond, the BMW
Assist Response Center can take further
steps to help you under certain circumstan‐
ces.
For this purpose, data that are used to de‐
termine the necessary rescue measures,
such as the current position of the vehicle if
it can be established, are transmitted to the
BMW Assist Response Center.▷If the LED is flashing but the BMW Assist
Response Center cannot be heard on the
hands-free system, the hands-free system
may be malfunctioning. However, the BMW
Assist Response Center may still be able to
hear you.

quest is automatically initiated immediately after
a severe accident. Automatic Collision Notifica‐
tion is not affected by pressing the SOS button.

The warning triangle is located on the inside of
the trunk lid.
To remove, loosen the bracket.
First aid kit
The first aid kit is located in the cargo area in a
storage compartment.

clock in many countries. You can obtain assis‐
tance there in the event of a vehicle breakdown.

Do not touch live parts
To avoid the risk of potentially fatal injury,
always avoid all contact with electrical compo‐
nents while the engine is running.◀
Preparation1.Check whether the battery of the other ve‐
hicle has a voltage of 12 volts. This informa‐
tion can be found on the battery.2.Switch off the engine of the assisting vehi‐
cle.3.Switch off any electronic systems/power
consumers in both vehicles.
Bodywork contact between vehicles
Make sure that there is no contact be‐
tween the bodywork of the two vehicles; other‐
wise, there is the danger of short circuits.◀
Starting aid terminals Connecting order
Connect the jumper cables in the correct
order; otherwise, there is the danger of injury
from sparking.◀
The so-called starting aid terminal in the engine
compartment acts as the battery's positive ter‐
minal.
Open the cover of the starting aid terminal.
The body ground or a special nut acts as the
negative terminal.
Connecting the cables
1.Open the cover of the BMW starting aid ter‐
minal.2.Attach one terminal clamp of the positive
jumper cable to the positive terminal of the
battery, or to the corresponding starting aid
terminal of the assisting vehicle.3.Attach the other end of the cable to the pos‐
itive terminal of the battery, or to the corre‐
sponding starting aid terminal of the vehicle
to be started.4.Attach one terminal clamp of the negative
jumper cable to the negative terminal of the
battery, or to the corresponding engine or
body ground of assisting vehicle.5.Attach the other end of the cable to the neg‐
ative terminal of the battery, or to the corre‐
sponding engine or body ground of the ve‐
hicle to be started.
Starting the engine
Never use spray fluids to start the engine.
1.Start the engine of the assisting vehicle and
let it run for several minutes at an increased
idle speed.2.Start the engine of the vehicle being started
in the usual way.
If the first starting attempt is not successful,
wait a few minutes before making another
attempt in order to allow the discharged bat‐
tery to recharge.Seite 292MobilityBreakdown assistance292

Vehicle care
Car care products
BMW recommends using cleaning and care
products from BMW, since these have been
tested and approved.
Car care and cleaning products
Follow the instructions on the container.
When cleaning the interior, open the doors or
windows.
Only use products intended for cleaning vehi‐
cles.
Cleansers can contain substances that are dan‐
gerous and harmful to your health.◀
Vehicle paint
Regular care contributes to driving safety and
value retention.
Environmental influences can act on the vehicle
paint. Tailor the frequency and extent of your car
care to these influences.
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.Seite 297CareMobility297
