2008 BMW 335I CONVERTIBLE ignition

Replacing components
232 For care and maintenance of the headlamps,
please follow the instructions in the separate
Caring for your vehicle brochure.
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 to 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 n ly b y a BM W c e n t e r o r a w o r k s h o p t h a t w o r k 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.<
Access to the lamps
1.Switch off the lamps and take the remote
control out of the ignition lock.
2.Remove the upper cover from the head-
lamp. To do so, use a screwdriver to press the catches towards the rear, see arrows,
and pull the cover forward and out.
Follow the same steps in reverse order to reat-
tach the cover.
Be careful when installing the cover, oth-
erwise leaks could occur and cause dam-
age to the headlamp system.<

Using a tow fitting
The screw-in tow fitting must always be carried
in the car. It can be screwed in at the front or
rear of the BMW.
Coupe: it is sto red in the onboard tool kit under-
neath the cover on the right-hand side of the
cargo bay, refer to page231.
Convertible: it is stored in the onboard tool kit
underneath the cargo bay floor, refer to
page231.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing on paved roads only. Avoid
lateral loading of the tow fitting, e.g. do not lift
the vehicle by the tow fitting. Otherwise the tow
fitting and the vehicle could be damaged.<
Access to screw thread
Rectangular cover panel in bumper:
Press on the upper edges of the cover panel.
Front
Rear
Being towed
Make sure that the ignition is switched on,
refer to page59, 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.<
Switch on the hazard warning flashers, depend-
ing on local regulations.
Manual transmission
Gearshift lever in idle position.
Automatic transmission
Selector lever in position N.
Changing selector lever positions, refer to
page62.
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
I n s o m e c o u n t r i e s , i t i s i l l e g a l t o t o w y o u r v e h i c l e
with a tow bar or tow rope on public highways.
Please familiarize yourself with the relevant
towing regulations for the country in which you
are driving.
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.<

Giving and receiving assistance
240
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 flat bed.
Do not tow the vehicle with just the rear axle
raised as this may cause the steering to turn.
Do not lift the vehicle by a tow fitting or
body and chassis parts, otherwise dam-
age may result.<
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
page237. 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 page59.
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, page90.<
