engine BMW 323i 2006 Workshop Manual

Replacing components
206 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 at a time, otherwise this could
cause irritation to the retina.<
Xenon lamps*
The service life of these bulbs is very long and
the probability of a failure is very low, provided
that they are not switched on and off an unusual
number of times. If a xenon lamp fails neverthe-
less, switch on the fog lamps and continue the
journey with great care, provided that local leg-
islation does not prohibit this.
Have work on the xenon lighting system
performed only by your BMW Center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. Due to the high electrical voltages
present, there is a risk of potentially fatal acci-
dents if work is performed inappropriate.<
Parking lamps, roadside parking lamps
In the event of a malfunction, please contact
your BMW Center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.
Halogen lamps
H7 bulb, 55 watts
Always wear gloves and eye protection;
the atmosphere within the H7 bulb is
pressurized. Otherwise there is a risk of injury if
the bulb is damaged.<
There are separate headlamp covers for low-
beam headlamps and high-beam headlamps.
Be careful when installing the covers, oth-
erwise leaks could occur and cause dam-
age to the headlamp system.<
For checking and adjusting headlamp
aim, please contact your BMW Center.<
Access to the lamps
The high-beam headlamp can be accessed
from the engine compartment, whereas the low-beam headlamp is accessed through a flap
in the wheel well.

according to BMW repair procedures with cor-
respondingly trained personnel.
Changing wheels
Your BMW is equipped with Run-Flat Tires as
standard. This removes the need to change a
wheel immediately in the event of a puncture.
The symbol identifying Run-Flat Tires is a circle
with the letters RSC on the sidewall, refer to
Run-Flat Tires, page196.
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, moreover, no spare wheel is
available. Your BMW Center will be glad to
advise you. Refer also to New wheels and tires,
page196.
The tools for changing wheels are avail-
able as optional accessories from your
BMW Center.<
Jack mounting points
The jacking points are at the positions shown in
the illustration.
Vehicle battery
Battery care
The battery is 100 % maintenance-free, the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Center will be glad to advise in
all matters concerning the battery.
Charging the battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine off. Connections, refer to Jump starting
on page212.
Disposal
Have old batteries disposed of by your
BMW Center or hand them in to a recy-
cling center. Maintain the battery in an upright
position for transport and storage. Always
secure the battery against tipping over during
transport.<
Power failure
After a temporary power loss, the functioning of
some equipment may be limited and require ini-
tialization. Individual settings may likewise have
been lost and will have to be reprogrammed:
>Time and date
These values must be updated, refer to
page77.
>Radio
In some cases, stations may have to be
stored again, refer to page150.
>Navigation system
Operability must be waited for, refer to
page124.
>Seat and mirror memory
The positions must be stored again, refer to
page44.
>Inside rearview mirror with digital compass
The system must be calibrated, refer to
page105.
Fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating, oth-
erwise this could lead to a circuit overload, ulti-
mately resulting in a fire in the vehicle.<

First aid pouch*
The first aid pouch is located on the right-hand
side of the luggage compartment in a storage
area.
Some of the articles contained in the first aid
pouch have a limited service life. Therefore,
check the expiration dates of the contents reg-
ularly and replace any items in good time, if nec-
essary.
Warning triangle*
The warning triangle is located on the left-hand
side of the luggage compartment. Press the tab
to take it out.
Jump starting
If the car's own battery is flat, your BMW's
engine can be started by connecting two
jumper cables to another vehicle's battery. You
can also use the same method to help start
another vehicle. Only use jumper cables with
fully-insulated clamp handles.
Do not touch any electrically live parts
when the engine is running, or a fatal acci-dent may occur. Carefully adhere to the follow-
ing sequence, both to prevent damage to one or
both vehicles, and to guard against possible
personal injuries.<
Preparation
1.Check whether the battery of the other
vehicle has a voltage of 12 volts and
approximately the same capacitance in Ah.
This information can be found on the bat-
tery.
2.Switch off the engine of the assisting vehi-
cle.
3.Switch off any consumers in both vehicles.
There must not be any contact between
the bodies of the two vehicles, otherwise
there is a danger of shorting.<
Connecting jumper cables
Connect the jumper cables in the correct
order, so that no sparks which could
cause injury occur at the battery.<
Your BMW has a jump-starting connection in
the engine compartment which acts as the bat-
tery's positive terminal, refer also to the Engine
compartment overview on page199. The cap is
marked with +.
1.Pull the cap of the BMW jump-starting con-
nection up to remove.
2.Attach one terminal clamp of the plus/+
jumper cable to the positive terminal of the
battery or a starting-aid terminal of the vehi-
cle providing assistance.
3.Attach the second terminal clamp of the
plus/+ jumper cable to the positive terminal

or negative pole.
5.Attach the second terminal clamp of the
minus/– jumper cable to the negative termi-
nal of the battery or to the engine or body
ground of the vehicle to be started.
Starting the engine
1.Start the engine of the donor vehicle and
allow it to run for a few minutes at slightly
increased idle speed.
2.Start the engine on the other vehicle in the
usual way.
If the first start attempt is not successful,
wait a few minutes before another attempt
in order to allow the discharged battery to
recharge.
3.Let the engines run for a few minutes.
4.Disconnect the jumper cables by reversing
the above connecting sequence.
If necessary, have the battery checked and
recharged.
Never use spray fluids to start the
engine.<
