Things to remember when driving
Break-in procedures
To ensure that your vehicle continues to
furnish optimized economy of operation
throughout an extended service life, we
request that you devote careful attention
to the following information.
Engine and differential
Up to 1,200 miles/2,000 km:
During this initial period you should attempt
to avoid constant, steady-state operation
and vary both vehicle and engine speeds
as often as possible. Until the break-in
period has been completed you should
also refrain from exceeding the following:
>4,500 rpm or 105 mph/170 km/h
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kick-down mode during
these initial miles.
Once you have driven 1,200 miles/
2,000 km, the engine or vehicle speeds can
be gradually increased.
Tires
Due to technical factors associated with
their manufacture, tires do not achieve their
full traction potential until after an initial
break-in period. Therefore, drive reservedly
during the first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve opti-
mized contact and wear patterns between
brake pads and rotors.
Following component replacements
Observe the break-in instructions again if
previously addressed components must be
replaced again during driving later.
General driving notes
Hot exhaust system
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Do not remove
the heat shields installed adjacent to vari-
ous sections of the exhaust system, 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 lead
to a fire, accompanied by the risk of serious
property damage as well as personal
injury.<
Air conditioning
Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed
water under the vehicle are thus normal.
Before driving into a car wash
1.Fold in the exterior mirrors, refer to
page53, as otherwise they could be
damaged due to the width of the vehicle
2.Leave the remote control in the ignition
lock, as otherwise the P position of the
automatic transmission will automati-
cally be selected when the remote con-
trol is removed. Refer to page63
and69.
With Comfort Access, be sure to
observe the instructions on page63
3.Release the parking brake, especially
when you have activated Automatic
Hold. Refer to page64 and65.

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 surface. This phenomenon is referred
to as hydroplaning, and is characterized by
a partial or complete loss of contact
between tires and road surface, ultimately
undermining your ability to steer and brake
the vehicle.<
Driving through water
Only drive through water with a maxi-
mum depth of 1 ft/30 cm, and then
only at walking speed at the most. Other-
wise, the vehicle's engine, the electrical
systems and the transmission may be dam-
aged.<
Safe braking
Your BMW is equipped with ABS as stan-
dard equipment. The best way to brake is
to apply maximum pressure to the brake
pedal during emergency: full brake applica-
tion. Since the vehicle maintains steering
responsiveness, you can nevertheless
avoid possible obstacles with a minimum
of steering effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate to the driver that ABS is in its active
mode.
Driving in wet conditions
While driving in wet conditions and 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 maneu-
ver does not endanger 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 reduced
efficiency of the brake system, drive
long or steep downhill gradients in the gear
in which the least braking is required. Otherwise, even light but consistent pedal
pressure can lead to high temperatures,
brake wear and possibly even brake fail-
ure.<
You can further enhance the engine's brak-
ing effect by selecting a lower gear in the
automatic transmission's manual mode,
downshifting as far as first gear on
extremely steep stretches, refer to
page70. This strategy helps you avoid
placing excessive loads on the brake sys-
tem.
Never allow the vehicle to coast with
the transmission in Neutral – or with
the engine switched off – as there is no
engine braking when the transmission is in
Neutral, and no power-assist for brakes
and steering when the engine is not run-
ning.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.<
Corrosion on brake rotors
When the vehicle is driven only occasion-
ally, 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 ten-
dency for corrosion to form on rotors, while
contaminants accumulate on the brake
pads. This occurs because the minimal
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 pul-
sating effect that even extended applica-
tion will fail to cure.
Mobile communications devices in
vehicle
BMW does not recommend using
mobile communications devices, e.g.
portable phones, in the interior of the vehi-
cle without a direct connection to an out-
side antenna. Otherwise the vehicle elec-
tronics and mobile communications device
can affect each other. In addition, it is not

DVD changer

Malfunctions/notes
The BMW DVD changer is a 'Class 1'
laser product. Never remove the
cover from the housing. Do not operate the
unit if the cover is damaged. Operation
without the cover can lead to serious eye
injury from invisible laser beams.
Always refer all repair and maintenance
operations to qualified technicians.
With self-recorded CDs or DVDs, labels
applied later can become detached during
playback due to the development of heat,
causing irreparable damage to the
device.<

To prevent CDs from being copied
illegally, they are often provided with
copy protection by the manufacturer.
Under certain circumstances this can pre-
vent or restrict the playing of CDs on the
DVD changer. In this case please contact
the CD dealer or manufacturer.<
If you play self-recorded audio CDs, faults,
e.g. drop-outs, can occur, or the CD is not
played at all.
The DVD changer can play the following
formats:
>Video DVD
>CD-DA, Audio CD
>CD-R.The DVD Audio format is not sup-
ported by the DVD changer. However,
many audio DVDs available in stores also
contain a video track in the DVD Video for-
mat in addition to the audio track. These
DVDs can be played back by the DVD
changer. Please refer to the information on
your DVD to determine whether your audio
DVD contains an additional video track.
DVDs are usually divided into tracks and
chapters and can contain different subti-
tles, camera angles or sound tracks, lan-
guages and sound formats. Depending on
the version of the DVD, these functions can
be selected either directly with the DVD
control system or only via the DVD-specific
menu. Refer to the information on your DVD
for possible selections.
High levels of humidity inside the player
can condense on the laser's scan lens and
prevent it from reading the DVD.
Do not use combined CD/DVD, e.g. DVD+,
as otherwise the CD/DVD can jam, prevent-
ing it from being ejected.<

Safety notice
A car phone can provide many services, in
an emergency even initiating a lifesaving
rescue. However, bear the following in
mind:
Adjustments
To avoid posing an unnecessary haz-
ard due to inattention, both to your
own vehicle's occupants and to other road
users: never attempt to use the controls or
make entries unless traffic and road condi-
tions allow.<
Using the phone in your vehicle
Using a portable phone to make and
receive calls while driving is now ille-
gal in virtually every country in the world.
Always use your hands-free system, or
stop your vehicle in an area where you will
not pose a safety hazard to other road
users and switch the engine off.<
Antenna
When using the phone, ensure that all
persons in the area are at least 20 in/
50 cm from the antenna. Never use your
BMW portable phone if the antenna is dam-
aged. Contact between your skin and a
damaged antenna can result in minor
burns.
I f t h e a n t e n n a i s d a m a g e d , h a v e i t r e p l a c e d
immediately.<
Special environmental conditions
Do not use your phone within a
garage, or near an open hood. The air
in these areas could contain fuel vapors,
and the portable phone might generate
sparks that could result in burns.
This same precaution applies to opening
luggage compartment lids on vehicles
equipped for operation using natural gas or
hydrogen, and to all vehicles with luggage
compartment-mounted batteries.Always switch off your BMW portable
phone in areas where blasting work is
being conducted with explosives. The
phone signals could potentially act as a
high-frequency transmitter and set off
explosions.
Always switch off your BMW portable
phone in areas where an increased explo-
sion danger is present. This category
includes filling stations along with fuel and
chemical storage depots, etc., and all areas
in which the air can contain fuel, chemicals
or metal particles. Under these conditions,
your BMW portable phone could conceiv-
ably generate sparks that could lead to a
fire or explosion. Always observe all legal
regulations governing the use of portable
phones in the vicinity of filling stations,
chemical factories and other areas where
an explosion potential exists.
Never use the BMW portable phone in hos-
pitals, care centers or at other locations
where medical equipment may be in oper-
ation, such as accident sites, etc.
Your wireless service provider can furnish
you with more detailed information on legal
regulations governing the use of your
phone.<
Medical equipment
Portable phones can generate inter-
ference capable of preventing hearing
aids and cardiac pacemakers from operat-
ing correctly. If you or any occupant of the
vehicle use such equipment, consult a phy-
sician or the manufacturer of the equip-
ment to determine whether it is adequately
shielded against high-frequency energy.
Persons with cardiac pacemakers should
bear the following in mind:
Always hold the switched-on BMW porta-
ble phone more than 6 in/15 cm away from
the cardiac pacemaker.
Do not carry the BMW portable phone in
your breast pocket.
Use the ear on the opposite side of the car-
diac pacemaker to reduce the likelihood of

Refueling
Fuel filler door
Always switch off the engine before
refueling. If you do not, fuel cannot be
filled into the tank and a message will
appear in the Check Control.<
To open and close: briefly press the rear
edge of the fuel filler door.
Manual release
In the event of an electrical defect in the
system, you can release the fuel filler door
manually:
1.Lift the handle to remove the cover
panel on the right side of the luggage
compartment
2.Take the button with the fuel pump
symbol from the bracket and pull it to
unlock the fuel filler door.
Always observe all applicable precau-
tions and regulations when handling
fuels. Never carry spare fuel containers in
your vehicle. Whether empty or full, these
containers can leak, cause an explosion,
and lead to fire in the event of a collision.<
Simple and environmentally friendly
When handling fuels always observe
any safety guidelines posted at the
filling station.<
Put the filler cap in the bracket attached to
the fuel filler door.
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Lifting the filler
nozzle during refueling
>results in premature pump shutoff
>can lead to reduced efficiency in the
fuel-vapor recovery system.
The fuel tank is full when the filler nozzle
clicks off the first time.
Closing fuel filler cap
Close the filler cap carefully after refu-
eling, continuing until you hear the
detent engage. While closing, be sure not
to squeeze the strap which is fastened to
the cap. A loose or missing cap will activate
a message
* in the Check Control.<
Fuel tank capacity
Approx. 23.2 US gallons/88 liters, including
the reserve capacity of approx. 2.6 gallons/
10 liters.
Never attempt to continue driving
until the tank is completely empty, as
engine functions could be affected, and the
vehicle could sustain damage as a result.<

Fuel specification
The engine uses lead-free gasoline only.
Required fuel
Premium unleaded gasoline,
minimum octane rating: 91
Minimum octane rating corresponds to the
Anti Knock Index AKI and is determined
according to the so-called (R+M)/2
method.
Do not use leaded gasoline, as other-
wise the lambda probe and catalytic
converter will be permanently damaged.<
Use high-quality brands
Field experience has indicated significant
differences in fuel quality: volatility, compo-
sition, additives, etc., among gasolines
offered for sale in the United States and
Canada. Fuels containing up to and includ-
ing 10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight, that is,
15 % MTBE or 3 % methanol plus an equiv-
alent amount of co-solvent, will not void the
applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may
result in drivability, starting and stall-
ing problems, especially under certain
environmental conditions such as high
ambient temperature and high altitude.
Should you encounter drivability problems
which you suspect could be related to the
fuel you are using, we recommend that you
respond by switching to a recognized high-
quality brand.
Failure to comply with these recommenda-
tions may result in unscheduled mainte-
nance.<

Checking oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature
3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
4.Carefully push the dipstick all the way
into the guide tube and pull it out again 5.The oil should extend to between the
two marks on the dipstick.
As is the case with fuel economy, the rate
at which the engine uses oil is strongly
influenced by driving style and operating
conditions.
The oil quantity between the two marks
of the dipstick is approx. 1.65 US quarts/

Under the hood
196 1.5 liter. Do not fill beyond the upper mark
on the dipstick. Excess oil can damage the
engine.
Adding engine oil
Wait until the level has dropped to just
above the lower mark or a message
appears in the Check Control before add-
ing oil.
Store oil, grease etc., well out of the
reach of children; always observe all
warning labels on the containers.<
Specified engine oils
The quality of the engine oil selected has
critical significance for the operation and
service life of an engine. BMW approves
only specific oils after confirming their suit-
ability for use in its vehicles with extensive
testing.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If you are unable to obtain BMW High Per-
formance Synthetic Oil, you can add small
amounts of another synthetic oil between
oil changes. Use only oils with the API SH
specification or higher.
Ask your BMW center for details con-
cerning the specific BMW High Per-
formance Synthetic Oil or synthetic oils
which have been approved.<
You can also call BMW of North America
at 1-800-831-1117 or visit this website:

tion.
BMW engines are designed to oper-
ate without additives, and their use
could even lead to damage in some
cases.<
Viscosity ratings
Viscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in the
area where you typically drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.
Coolant
Do not add coolant to the cooling sys-
tem when the engine is hot. Escaping
coolant can cause burns.<
Coolant consists of water and the addition
of antifreeze and anticorrosion agent. Not
all commercially available additives are
suitable for your BMW. Ask your BMW cen-
ter for suitable additives.
Only use suitable additives, as other-
wise engine damage may result. The
additives present a health hazard; observe
the instructions on the containers.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used anti-
freeze and anticorrosion agents.<
Checking coolant level
1.The engine must be at ambient temper-
ature
2.Turn the cap of the expansion tank
counterclockwise to allow any accumu-
lated pressure to escape, then continue
turning to open
3.The coolant level is correct when the
coolant extends to between the MIN
and MAX marks on the filler neck, refer
to the diagram adjacent to the filler neck
