Notes
If the vehicle is not maintained according to
these specifications, this
could result in serious
damage to the vehicle. Such damage is not
covered by the BMW New Vehicle Limited
Warranty.
Data memory
A variety of electronic components in your vehi-
cle include data storag e devices, which store
technical information on the condition of your
vehicle, events and errors, either temporarily or
permanently. In general, this technical informa-
tion documents the condition of a component, a
module, a system or the surroundings:
> Operating conditions of system compo-
nents, e.g., fill levels.
> Status messages regarding the vehicle and
of its individual components, such as wheel
rpm/vehicle speed, resp onse delay, lateral
acceleration.
> Malfunctions and defects in the major sys-
tem components, such as the lights and
brakes.
> Responses of the vehicle in special driving
situations, such as the deployment of an
airbag, the utilization of stability control
systems.
> Environmental conditions, such as
temperature.
These data are exclusively of a technical nature
and are used for the detection and correction of
errors, as well as the optimization of vehicle
functions. Motion profiles of traveled routes can
not be deduced from these data. If services are
required, such as repair services, service pro-
cesses, warranty claims and quality assurance,
then this technical information can be read out
by employees of service departments, includ-
ing the manufacturer, from the event and error
data storage devices by using special diagnos-
tic equipment. There, if necessary, you will receive further informatio
n. After remedying an
error, the information in the error memory is
deleted or progressively overwritten.
When using the vehicle, situations are conceiv-
able in which this techni cal data, in conjunction
with other information, such as accident
reports, vehicle damage, witness statements,
etc. - possibly with the assistance of an expert -
could be traced to pa rticular individuals.
Additional functions that are agreed upon
contractually with the cu stomer, such as vehi-
cle tracking in case of emergency, permit the
transmission of certain vehicle data from the
vehicle.
Reporting safety defects
For US customers
The following only app lies to vehicles owned

Start/Stop button.
If the transmission is shifted into N when
the engine is switched off, you will be
notified visually and acoustically of this
fact.
2. Forcefully apply the parking brake.
3. Remove remote contro l from the ignition
lock, refer to page 61. The transmission is
automatically shifted into transmission
position P.
Parking brake
The parking brake is primarily intended to pre-
vent the vehicle from rolling while parked; it
brakes the rear wheels.
Also follow the instructions on page 63, under
Switching off the engine.
Indicator lamp
The indicator lamp is lit, and when you
drive off a signal sounds in addition.
The parking brake is still applied.
Indicator lamp for Canadian models.
Applying
The lever locks in po sition automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
In exceptional cases, if the parking brake
has to be used to slow or stop the car, do
not pull the lever up too hard. In doing so, con-
tinuously press the button of the parking brake
lever.
Otherwise, excessive force on the parking
brake can lock up the rear wheels and cause the
rear of the car to swerve. <
To prevent corrosion and one-sided brak-
ing action, occasionally apply the parking
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the park-
ing brake is applied. <

Technology for driving comfort and safety
Controls
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limit s that apply to all forms
of ultrasonic measurement, such as those
encountered with traile r towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g. curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Loud sound sources out-
side or inside the car can drown out the PDC
signal. Therefore, always drive cautiously; oth-
erwise, there is a risk of personal injury or prop-
erty damage. <
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page 126.
Electronic brake-force distribution
EBV
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploi ts all of the benefits
provided by ABS.
Do not reduce the pressu re on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull aw ay from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through brakin g actions at the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains th e responsibility of the
driver. Therefore, do no t reduce the additional
s a f e t y m a r g i n a g a i n b y t a k i n g r i s k s , a s t h i s c o u l d
result in an accident. <
Deactivating DSC
Press the button for at least 3 seconds until the
indicator lamp for DSC OFF lights up and DSC
OFF is displayed in the instrument cluster.
Dynamic Traction Cont rol DTC and DSC have
been simultaneously de activated. Stabilizing
and drive-output promoting actions are no
longer executed.

Things to remember when driving
Vehicle equipment
In this chapter, all pr oduction, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follo w the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed an engine speed of 4,500 rpm or a
road speed of 100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full
traction potential until af ter an initial break-in
period. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.
Clutch
The function of the clut ch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewe d in the course of the
vehicle's operating life.
Saving fuel
The fuel consumption of your vehicle depends
on several factors. You can lower fuel consump-
tion and the environmental impact by taking
certain measures, adjusting your driving style
and having the vehicl e serviced regularly.
Remove any unneeded cargo
Additional weight increases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove unneeded additional mirrors, the roof
rack and the rear luggage rack after use.
Mounted parts affect th e vehicle's aerodynam-
ics and increase fuel consumption.
Close the windows and glass roof
An open glass roof or window causes higher
air resistance and thus increases fuel
consumption.

Driving tipsThings to remember when driving
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the he at shields installed in
its vicinity, and never apply undercoating to
them. When driving, standing at idle and while
parking, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could le ad to a fire, with the
risk of serious personal injuries and property
damage. Do not touch hot exhaust tail pipes.
Otherwise, there is a risk of burns. <
Mobile phones in the vehicle
It is not advisable to use wireless devices
such as mobile phones inside the vehicle
without a direct connection to an external aerial.
Otherwise, it is not poss ible to exclude the pos-
sibility of a reciprocal interference occurring
between the vehicle electronics and the wire-
less device. Otherwise, there is no assurance
that the radiation genera ted by the radio trans-
mission will be conveyed out of the passenger
compartment.<
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This situation, known as hydroplaning,
means that the tire can completely lose contact
with the road surface, so that neither the car can
be steered nor the brak e be properly applied.<
The risk of hydropla ning increases with
declining tread depth on th e tires, refer also to
Minimum tread depth on page 229.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged. <
Use the parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Otherwise, greater
clutch wear will result. <
For more information about the drive-off
assistant, refer to page 90.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Sinc e the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Objects in the movement range of the
pedals
Keep floor mats, carpet, and other objects
out of the movement range of the pedals;
otherwise, they may inhi bit the function of the
pedals during driving.
Do not place additional floor mats onto an
existing one or onto other objects.
Only use floor mats that have been approved for
the vehicle and can be appropriately fastened.
Make sure that the fl oor mats are securely
fastened again after they have been removed,
e.g. for cleaning. <
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pre ssure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors. Full
braking efficiency will th en be available when
you need it.

Things to remember when driving
Driving tips
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least br aking is required. Even
light but consistent brak e pressure can lead to
high temperatures, brake wear and possibly
even brake failure. <
You can increase the engine's braking effect
by shifting down, all the way to first gear if nec-
essary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mo de of the automatic
transmission, refer to page 65.
Sport automatic transm ission with double
clutch: never drive with the transmission
in neutral or with the en gine switched off; other-
wise, there will be no en gine braking action and
no power assistance to the brakes and steering.
Manual transmission: never drive with the
clutch held down, with the transmission in neu-
tral or with the engine switched off; otherwise,
there will be no engine braking action and no
power assistance to the brakes and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals; otherwise, pedal function could be
impaired. <
Corrosion on brake rotors
When the vehicle is driv en only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are le ss frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminan ts 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 the vehicle is parked
Condensation forms while the automatic
climate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Cargo loading
To avoid loading the tires beyond their
approved carrying ca pacity, never over-
load the vehicle. Overlo ading can lead to over-
heating and increases the rate at which damage
develops inside the tires. In some situations,
this can result in sudden loss of tire pressure. <
Avoid fluid spills in the trunk as they could
damage the vehicle. <
Determining loading limit
1.Locate the following statement on your
vehicle's placard:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise damage to
the vehicle may occur and unstable driving
conditions may result.<
2. Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.
4. The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals

Headlamps
Do not rub them dry and do not use abrasive or
corrosive cleaning agents.
Loosen dirt, e.g. insects, with shampoo and
rinse away with water.
Thaw ice with a de-icer and do not use an ice
scraper.
After washing the vehicle
After washing the vehicle, apply the
brakes briefly to dry them; otherwise,
water can reduce braking efficiency over the
short term and the brake discs can corrode. <
R e m o v e r e s i d u e s o n t h e windows completely in
order to prevent impaired vision due to smear
formation and to reduce wiper noise and wiper
blade wear.
Vehicle care
Care products
BMW recommends using BMW cleaning and
care products since they have been tested and
approved for this purpose.
Follow the instructions on the packaging.
When cleaning inside the vehicle, always
open the doors and windows. Only use prod-
ucts designed for cleaning vehicles. Cleaning
agents can contain substa nces that are danger-
ous or hazardous to your health. <
Vehicle paintwork
Regular care contributes to driving safety and
value retention. Environmental influences in
regions with elevated levels of air pollution or
natural contaminants such as tree sap or pollen
can impact vehicle paintwork. The frequency
and scope of car care should be adapted
accordingly.
Immediately remove particularly corrosive sub-
stances such as spilled fuel, oil, grease, or bird
droppings to prevent damage to the paintwork.
Leather care
Frequently remove dust from the leather using
a cloth or vacuum cleaner.
Otherwise, dust and road grit in the pores and
folds of the leather will otherwise have an abra-
sive effect, resulting in increased wear and
causing the leather surf ace to become brittle
prematurely.
