Tire Pressure Control (RDC)
*
In the event of a flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with 
a red lamp. In addition, an acoustic 
signal is sounded.
If this occurs, reduce vehicle speed 
immediately to stop the vehicle in a safe 
location. Avoid hard brake applications. 
Do not oversteer. Replace the wheel 
and flat tire.
The space-saver spare tire is 
provided for temporary use only in 
the event of a flat tire. It does not have 
RDC electronics and is not monitored.<
RDC cannot alert you to severe 
and sudden tire damage caused 
by external factors.<
Have the tires changed by your 
BMW center. 
Your BMW center has been trained to 
work with the RDC system and is 
equipped with the necessary special 
tools.<
System interferenceLocal devices using the same radio 
frequency can interfere with the RDC.
The yellow indicator lamp will come on 
during the malfunction. 
The indicator lamp also comes on
>in the event of a system fault. 
>if a wheel is mounted without RDC 
electronics. 
>if additional wheels with RDC elec-
tronics are on board.
Please contact your BMW center for 
additional information.

Changing a wheel Battery Driving with the space-saver 
spare tireDrive cautiously and do not exceed a 
speed of 50 mph (80 km/h).
Be aware that vehicle handling will be 
altered. Slower brake response time, 
longer braking distances and changed 
steering characteristics may be 
anticipated when approaching limit 
conditions. 
The changes in handling characteristics 
will be even more pronounced in 
conjunction with winter tires.
Only one space-saver spare tire
* 
may be mounted at a time. Mount 
a wheel and tire with the same size 
and specifications as the others at the 
earliest possible opportunity. Maintain 
correct tire pressures. Refer to 
page 28.<
LocationThe battery is located at the right-rear 
of the luggage compartment. Remove 
the luggage compartment floor panel 
(refer to page 40), and give a screw-
driver or a coin a f-turn counter-clock-
wise to release and remove the two 
fasteners, plus an additional fastener in 
the top center side trim panel. In order 
to remove the storage tray, slide the 
side trim panel slightly upward.
Battery posts, terminals, and 
related accessories contain lead 
and lead compounds. Wash hands after 
handling.<46cde045
