2010 BMW 3 SERIES ignition

Replacing components
230 do not feel competent to perform yourself or
that is not described here.
Never touch the glass of new bulbs with
your bare fingers, 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.<
You can obtain a selection of replacement bulbs
at your BMW center.
Only change bulbs while they are cool to
the touch; otherwise, you could suffer
burns.<
When working on electrical systems,
always begin by switching off the con-
sumer in question; otherwise, short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer.<
For care of the headlamps, please follow the
instructions in the chapter entitled 'Care'.
If the routine for changing a particular
bulb is not described here, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
Light-emitting diodes LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
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; otherwise, this could cause
irritation of the retina.<
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
o nl y b y a BM W c e n t er o r a w o r k s h o p t h a t w o rk s
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.<

3.Release the wire bracket from the anchor,
see arrow, and fold it up.
4.Disconnect the plug, change the bulb and
reconnect the plug.
5.Insert the bulb.
6.Fold the wire bracket down and engage it.
7.Reattach the cover.
Be careful when installing the cover; oth-
erwise, leaks could occur and cause dam-
age to the headlamp system.<
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.

To remove the covers:
1.Fold the respective wire bracket to the side,
see arrows.
2.Flip open the cover and take it out of the
guide.

Front
Rear
Being towed
Make sure that the ignition is switched on,
refer to page54; 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
page57.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.<
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.<

With a tow truck: vehicle without xDrive
Have the BMW transported with a tow truck
with a so-called lift bar, or on a flatbed.
Do not tow the vehicle with just the rear axle
raised as this may cause the steering to turn.
With a tow truck: vehicle with xDrive
Do not tow a BMW with xDrive with just
the front or rear axle raised; otherwise, the
wheels could lock up and the transfer case
could be damaged.<
Have the BMW transported on a flatbed surface
only.
Tow-starting
Avoid tow-starting the vehicle whenever possi-
ble; instead, jump-start the engine, refer to
page238. Vehicles with a catalytic converter
should only be tow-started when the engine is
cold, vehicles with an automatic transmission
cannot be tow-started at all.
1.Switch on hazard warning flashers, comply
with local regulations.
2.Switch on the ignition, refer to page54.
3.Shift into 3rd gear.
4.Have the vehicle tow-started with the clutch
depressed and slowly release the clutch. After the engine starts, immediately
depress the clutch completely again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
With xDrive: do not activate Hill Descent
Control HDC when the vehicle is being
tow-started, page83.<
