Changing tires9 Position the new wheel or the 
space-saver spare tire
* on the hub 
and screw at least two lug bolts 
finger-tight into opposite bolt holes 
10 Screw in the remaining lug bolts. 
Tighten all the bolts securely
11 Lower the jack and remove it from 
beneath the car
12 Tighten the lug bolts, alternating 
between bolts positioned opposite 
one another

13 If your wheels are equipped with full 
wheel covers
*: Position the wheel 
cover with the valve opening over 
the valve (arrow) and press it onto 
the wheel with both hands
14 Inflate tire to the proper pressure as 
soon as possible.
For vehicles with RDC Tire Pressure 
Control
*:
Reactivate the system after mount-
ing either the spare tire or after in-
flating tire to proper pressure. 
(Refer to page 82).
Only use original BMW full wheel 
covers, otherwise, the trim piece 
may not fit securely. The full wheel 
cover may not be installed on the 
space-saver spare tire
*, since this 
could damage the cover.<
462de279
The vehicle jack is designed for 
changing tires only. Never use it to 
raise another vehicle model or any load 
of any kind, as this could lead to acci-
dents and personal injury.
Have the lug bolts checked for proper 
tightness with a calibrated torque 
wrench at the earliest possibility [torque 
specification: 72 lb.ft. (100 Nm)].<
When storing the wheel, take care to 
ensure that you do not damage the re-
taining pin in the spare tire recess.
If light-alloy wheels other than Original 
BMW light-alloy wheels have been 
mounted, it may be necessary to use 
different lug bolts for those wheels.
Replace the defective tire as quickly as 
possible and have the new wheel bal-
anced.
For black-painted aluminum wheels
*, 
use only those balancing weights ap-
proved by BMW for use with light alloy 
wheels. Never attempt to balance these 
wheels using standard balance weights.

Deceleration sensors continuously 
monitor the physical forces acting upon 
the vehicle. If, as the result of a frontal 
collision, a deceleration is reached at 
which the protection of the safety belts 
alone is no longer adequate, the gas 
generators of the driver and passenger-
front airbags are ignited. However, the 
passenger-side airbag is only triggered 
if an additional sensor has recognized 
that the passenger seat is occupied. 
In the event of a side collision, the Head 
Protection and side airbags in the front 
or rear
* are triggered if necessary.

The airbags located under the marked
covers inflate and unfold in a matter of a 
few milliseconds. In this process they 
tear through the rated breaking points 
of the upholstered covers or press them 
out.
Because the inflation process must be 
virtually instantaneous, it is necessarily 
accompanied by a certain amount of 
ignition and inflation noise. The gas 
required to inflate the airbags is not 
dangerous, and the associated smoke 
then dissipates.
The entire process is completed within 
fractions of a second.Highly sensitive sensors monitor the 
number of revolutions of the wheels, 
steering angle, lateral acceleration, 
brake pressure and the movement of 
the vehicle around its vertical axis.
If differences in the wheel speeds oc-
cur, the system counteracts the danger 
of wheelspin by reducing engine torque. 
If necessary, the system also responds 
with additional application of the brakes 
at the rear wheels. 
If the system detects an instability in the 
vehicle's condition, the braking action 
can also be directed to the front wheels 
by the DSC in order to help stabilize the 
vehicle.
You may need some time to become 
accustomed to this system's interven-
tion. However, it provides optimum pro-
pulsive force and driving stability.
The braking intervention may be ac-
companied by a certain degree of 
noise.
