able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Servotronic*
The concept
The Servotronic varies the steering force
required to turn the wheels depending on the
speed at which you are driving. When you are
driving at low speeds, power steering provides
more support, i.e. little effort is needed to turn
the wheels. Power steering support lessens as
your speed increases.
The system works automatically.
Malfunction
Malfunctions are displayed via Check Control.
Dynamic brake lamps*
On the left: normal braking.
On the right: sharp braking.
During sharp braking, the brake lamps and the
dynamic brake lamps of your BMW light up.
The dynamic brake lamps are automatically
activated if the turn signal is not flashing.
Airbags
The following airbags are located under the
marked covers:
1 Front airbags
2 Side airbags in the seat backrests
3 Knee airbag
Protective action
Observe the adjustment instructions on
page
41 to ensure the best possible per-
sonal protection. <
The front airbags help protect the driver and
passenger by responding to frontal impacts in
which safety belts alone cannot provide ade-
quate restraint. When needed, the side airbags
help provide protection in the event of a side
impact. The relevant side airbag supports the
head and the side upper body area.
The airbags have been designed to not be trig-
gered in every collision situation, e.g., not in
minor accidents or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Keep the dashboard and window on the pas-
senger side clear, i.e., do not cover with adhe-
sive labels or coverings, and do not attach hold-
ers such as for navigation instruments and
mobile phones.
Do not attach seat covers, cushions or other
objects to the front seats that are not specifi-
cally approved for seats with integral side air-
bags. Do not hang items of clothing such as
coats or jackets over the backrests.
Do not attempt to remove the airbag retention
system from the vehicle. Do not modify the indi-
