Opening and closing
32 If special circumstances should make it
absolutely necessary to operate the vehicle
with the lid open:
1.Coupe: close both windows as well as
the glass roof
Convertible: with closed top, close all
windows
2.Adjust the automatic climate control to
supply a high air volume, refer to
page 89.
Luggage compartment
There are four lashing eyes on the inner
corners of the luggage compartment for
securing luggage nets or securing straps to
fix luggage in position.
Also refer to Cargo loading, page 104.
Convertible: increasing luggage
compartment capacity
With the convertible top closed, you can
enlarge the luggage compartment capac-
ity:
To do so, unfold the handle and press it
downwards in the direction of travel, refer
to arrow. This folds the convertible top
compartment floor upwards.
Before opening the convertible top, run this
procedure in reverse order.
The convertible top cannot be
opened if the convertible top com-
partment floor is folded up.<
Alarm system
The concept
The vehicle alarm system responds:
>When a door, the hood, or the luggage
compartment lid is opened
>To movement in the vehicle interior:
interior motion sensor
>To changing of the vehicle's tilt if some-
one attempts to steal the wheels or tow
the vehicle
>To interruption of battery voltage.
The system responds to unauthorized vehi-
cle entry and attempted theft by simulta-
neously activating:
>An acoustic alarm, which lasts for a
period of approx. 30 seconds
>The hazard warning flashers for approx.
5 minutes
>The high beams, which flash on and off
in the same rhythm.
Arming and disarming alarm system
When you lock or unlock the vehicle, either
with the remote control or at the door lock,
the alarm system is armed or disarmed at
the same time.
The system indicates that it has been cor-
rectly armed by switching on the hazard
warning flashers for a single cycle and by
emitting an acoustic signal.
You can also open the luggage compart-
ment lid with the system armed using but-
ton on the remote control, refer to
page 28. When you close the lid, it is
secured again.
Switching off alarm
>Unlock the vehicle using the remote
control, refer to page 27
>or turn the ignition key to position 1.

Safety notes
For your own safety
Your car phone makes life more convenient
in many ways, and can even save lives in an
emergency. While you should consult your
portable phone's separate Owner's Manual
for a detailed description of safety precau-
tions and information, we request that you
direct your particular attention to the fol-
lowing:
Adjustments
To avoid posing a danger to yourself
and other road users, never adjust the
system settings unless your vehicle is sta-
tionary.<
Using the phone in your vehicle
Using a portable phone while driving
is now illegal in many states and cit-
ies. 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.<
Vehicles and portable phones
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 open lug-
gage compartment lids on vehicles
equipped for operation using natural gas or
hydrogen, and to all vehicles with luggage
compartment-mounted batteries.<
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.
If the antenna is damaged, have it replaced
immediately.<
Special environmental conditions
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 gas 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 conceivably 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 gas
stations, chemical factories and other
areas where an explosion potential exists.
Never use your BMW portable phone in air-
craft; do not use this 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.<

Under the hood
170
Under the hood
Never attempt to perform any service
or repair operations on your vehicle
without the required, professional technical
training. If you are unfamiliar with the ser-
vice procedures and precautions, always
have any required work on your vehicle
carried out at your BMW center. If this work
is performed inexpertly, there is a danger of
damage and associated safety risks.<
Hood
Releasing
Pull the lever located under the left side of
the instrument panel.
Opening
Press the release handle and open the
engine hood.
Closing
Close the hood from a height of approx.
16 in/40 cm with momentum. It must be
clearly heard to engage.
Make sure that the closing path of the
engine hood is clear, as otherwise
injuries may result.
If you see any signs that the hood is not
completely closed while you are driving
your vehicle, you should stop at once and
close it securely.<

Under the hood

Topping up engine oil
Wait until the level has dropped to just on
the lower dipstick mark before adding oil.
In this area a message also appears on the
Control Display.
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 continu-
ously approves specific oils after confirm-
ing their suitability 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:
www.bmwusa.com to obtain this informa-
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 envi-
ronmental rules and regulations when
disposing of used coolant additives.<
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
