2008 BMW 650I CONVERTIBLE brake

Things to remember when driving
126 the road surface, ultimately undermining your
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, also refer to Mini-
mum tire tread on page213.
Driving through water
Do not drive through water on the road if it
is deeper than 1 ft/30 cm, and then only at
walking speed at the most. Otherwise, the vehi-
cle's engine, the electrical systems and the
transmission may be damaged.<
Using handbrake on inclines
On inclines, do not hold the vehicle in
place for a long time by riding the clutch;
use the handbrake. Otherwise, greater clutch
wear will result.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indicate to
the driver that ABS is in its active mode.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When driving on wet roads or in heavy rain, it is
a good idea to apply light pressure to the brake
pedal every few miles. Monitor traffic conditions
to ensure that this maneuver does not endan-
ger other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and thus reduced
efficiency of the brake system, downshift
to a gear in which only minimal brake applica-
tions are needed when descending long or
steep downhill stretches. Even light but consis-
tent pressure on the brake pedal can lead to
high temperatures, brake wear and possibly
even brake failure.<
The braking effect of the engine can be further
increased by downshifting, if necessary all the
way down into first gear. This strategy helps
you avoid placing excessive loads on the brake
system. For information on downshifting in the
manual mode of the sport automatic transmis-
sion, refer to page61.
Do not drive with the clutch depressed, in
idle or with the engine switched off, other-
wise there will be no engine braking action or
support of the braking force and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When vehicle is parked
Condensation forms in the automatic climate
control during operation, and then exits under
the vehicle. Traces of condensed water under
the vehicle are therefore normal.

It may not be possible to establish a telephone
connection using the mobile phone while a con-
nection is being established to BMW Assist
or while a call to BMW Assist is already in
progress. If this happens, you must unpair the
mobile phone and the vehicle if you wish to
place a call with the mobile phone.
Initial operation
Pairing mobile phone in vehicle
The following prerequisites must be met:
>Suitable mobile phone: the mobile phone is
supported by the full mobile phone prepara-
tion package. Information on this subject is
also provided on the Internet at:
www.bmw.com
>The mobile phone is ready to operate.
>The Bluetooth links of the vehicle, refer to
page189, and the mobile phone are active.
>Depending on the mobile phone, presets in
the mobile phone are required: e.g. via the
following menu items:
>Bluetooth activated
>Connection not with confirmation
>Reconnect
>Depending on the mobile phone model, the
setting energy saving mode can, for exam-
ple, result in vehicle failing to detect the
paired mobile phone.
>Specify any desired number as the Blue-
tooth passkey, e.g. 1, for pairing. This Blue-
tooth passkey is no longer required follow-
ing successful pairing.
>The ignition is switched on.
Only pair the mobile phone with the vehi-
cle stopped, otherwise the passengers
and other road users can be endangered due to
a lack of attentiveness on the part of the
driver.<
Switching on ignition
1.Insert the remote control as far as possible
into the ignition lock.
2.Switch on the ignition by pressing the Start/
Stop button without depressing the brake
or clutch pedal.
Preparation via iDrive
iDrive, for operating principle refer to page16.
3.Press the button to open the start
menu.

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air.
The ultimate objective is to ensure economical
maintenance by providing the ideal service for
your vehicle.
Should the day come when you decide to sell
your BMW, you will find that a complete dealer
service history is an asset of inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
You can set the Control Display to show
remaining distances and times of selected
maintenance intervals and legally mandated
deadlines, refer to page77:
>Engine oil
>Brake pads, front and rear separately
>Brake fluid>Vehicle check
>Legally required tests depending on local
regulations
Service data in remote control
Your vehicle stores the information required for
maintenance continuously in the remote con-
trol during driving. After accessing the data
stored in the remote control, your BMW Service
Advisor can suggest precisely the right array of
service procedures for your own individual vehi-
cle. For this reason, when you take your vehicle
in for service, you should give the BMW Service
Advisor the remote control last used to drive it.
Make sure the date is set correctly, refer
to page83, otherwise the effectiveness
of CBS Condition Based Service is not
ensured.<
Service and Warranty Information
Booklet for US models and
Warranty and Service Guide Booklet
for Canadian models
Please consult your Service and Warranty Infor-
mation Booklet for US models and Warranty
and Service Guide Booklet for Canadian models
for additional information on service require-
ments.
BMW recommends that you have service
and repair operations performed at your
BMW center.
Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
cle's Service and Warranty Information Booklet
for US models and Warranty and Service Guide
Booklet for Canadian models. These entries
verify that your vehicle has received the speci-
fied regular maintenance.<

Replacing components
224
Xenon lamps
The service life of these lamps 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 one of these bulbs should
nevertheless fail, it is possible to continue driv-
ing with great caution using the fog lamps, pro-
vided traffic laws in your area do 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 voltage involved, there
is a danger to life and limb when work is carried
out improperly.<

3.Remove and replace the bulb.
Always wear gloves and eye protection –
the atmosphere inside the H8 bulb is
pressurized. Otherwise, there is a danger of
injuries if the bulb is accidentally damaged dur-
ing replacement.<
Side-mounted turn signals
5-watt bulb, WY5W
1.Press against the front edge of the lamp
with the tip of your finger, then push it to the
rear, release the snap connection at the
front and take it off the trim strip.
2.Turn the bulb holder to the left by 905 and
remove.
3.Remove and replace the bulb.
Tail lamps
The parking lamps, tail lamps, brake
lamps, and turn signals use LED technol-
ogy. The backup lamps are equipped with long-
life bulbs. Please contact a BMW center in case
of a malfunction.<
