RDS transmits additional information in the FM
frequency range. RDS stations have the follow-
ing properties:
>In the case of broadcasting networks that
transmit over a number of frequencies,
there is an automatic switch to the fre-
quency with the best reception quality.
>If the reception conditions are good, the
station names are shown on the Control
Display. If the reception is weak or dis-
rupted, it can take some time before the
station names appear.
Weather Band*
Weather Radio is a service of the National Oce-
anic and Atmospheric Administration – NOAA –
of the U.S. Department of Commerce. Weather
messages are repeated every four to six min-
utes and are routinely revised every one to three
hours, or more frequently if needed. Most of the
stations operate 24 hours daily. During severe
weather, National Weather Service forecasters
can interrupt the routine weather broadcasts
and substitute special warning messages. If you
have a question concerning NOAA Weather
Radio, please contact your nearest National
Weather Service Office, or write to National
Weather Service – Attn: W/OM11 –, National
Oceanic and Atmospheric Administration,

Topping off engine oil
Wait until the level has dropped to just above
the lower dipstick mark before adding oil. When
it falls to this level, a message also appears on
the Control Display.
Refill the oil within the next 125 miles/
200 km, otherwise engine damage could
result.<
Store oil, grease etc., well out of the reach
of children; always observe all warning
labels on the containers.<
Oil change
Have oil changes carried out only by a BMW
center.
Specified engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Use only approved BMW High Performance
Synthetic Oil.
If you are unable to obtain BMW High Perfor-
mance Synthetic Oil, you can add small
amounts of another synthetic oil between oil
changes. Use only oils with the API SH specifi-
cation or higher.
Ask your BMW center for details concern-
ing the specific BMW High Performance
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 information.BMW engines are designed to operate
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 open the cooling system when the
engine is hot. Escaping coolant can cause
burns.<
Coolant consists of water and coolant additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives, as otherwise
engine damage may result. The additives
present a health hazard.<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.

Always observe all applicable towing laws
and regulations.<
Never allow passengers to ride in a towed
vehicle for any reason.<
Use tow fitting
The threaded tow fitting is stored in the tool kit
mounted on the inside of the luggage compart-
ment under the floor mat, refer to page180, and
should always remain in the vehicle. It can be
screwed in at the front or rear of the BMW.
To avoid damage to the tow fitting and the
vehicle, observe the following: only use
the tow fitting that comes with the vehicle and
screw it in as far as possible. Use the tow fitting
for towing only on roads. Avoid lateral strains on
the tow fitting, e.g. do not the lift vehicle by the
tow fitting.<

Being towed
Make sure that the ignition key is in posi-
tion 1, as otherwise the steering wheel
could lock and it would be impossible to steer
the vehicle. There is no power assist with the
engine stopped. This then requires increased
effort for braking and steering. Active steering is
deactivated and larger steering wheel move-
ments are required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Vehicles with manual transmission
Gearshift lever in idle position
Vehicles with automatic transmission
Selector lever in position N.
Do not exceed a towing speed of 45 mph/
70 km/h and a towing distance of
90 miles/150 km, as otherwise the automatic
transmission may be damaged.<
Vehicles with SMG Sequential manual
transmission
With the ignition switched on, engage selector-
lever position N, then switch off the ignition.
Towing methods
In some countries, towing with tow bars or
ropes in public traffic is not permitted.
Familiarize yourself with the regulations on tow-
ing in the respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, as otherwise
it will not be possible to control vehicle
response.<
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 offset
angle, please observe the following:
>Clearance and maneuvering capability will
be strictly limited during cornering.

>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Secure the tow bar to the tow fitting only.
Otherwise to other vehicle parts could
result.<
With 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.
Secure the tow rope to the tow fitting only. Oth-
erwise damage to other vehicle parts could
result.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a load bed.
Do not lift vehicle by tow fitting or body
and chassis parts, as otherwise damage
may result.<
Tow-starting
Do not tow-start vehicles with an auto-
matic transmission.
Jump starting, refer to page186.<
Only tow-start vehicles with a catalytic con-
verter with the engine cold. It is better to jump
