Vehicle equipment

In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehicle, for example due to
the special options or national-market version
selected. This also applies to safety related
functions and systems.

Tire inflation pressures

Information for your safety

It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.

Check the tire inflation pressure regularly
and correct it, if necessary: at least twice a

month and before starting long trips. If you fail
to observe this precaution you may be driving
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive
with deflated, i.e. flat tires, except when using
run-flat tires. A flat tire will seriously impair your
vehicle's handling and braking response.
Attempts to drive on a flat tire can lead to loss of
control over the vehicle.

Checking pressure

Only check tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure is higher.

After correcting the tire inflation pressure,
reset the Tire Pressure Monitor, refer to

page

103

, or reinitialize the Flat Tire Monitor,

refer to page

100

Inflation pressure specifications

The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.

The inflation pressures apply to the tire
sizes approved and tire brands recom-

mended by BMW; a list of these is available
from your BMW center.

For correct identification of the right tire infla-
tion pressures, observe the following:

Tire sizes for your vehicle

Maximum allowable driving speed

Tire inflation pressures for driving up to
100 mph or 160 km/h

For normal driving up to 100 mph or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of
100 mph or 160 km/h.
These tire inflation pressures can also be found
on the driver's side door pillar when the driver's
door is open.

The maximum permissible speed for
these tire pressures is 100 mph or

160 km/h. Do not exceed this speed; otherwise,
tire damage and accidents could occur.
