Winter operation Power steering Level control system
*
Skid controlRelease the accelerator pedal. Coun-
tersteer carefully and attempt to regain
control of the vehicle.ParkingPlace the selector lever in position P
(Park). Engage the parking brake when
parking on hills and inclined surfaces. In
order to prevent the parking brake lin-
ings from locking in the drum due to
frost or corrosion, dry them by gently
applying the parking brake as the vehi-
cle is coming to a stop. Make sure that
following traffic is not endangered.
The brake lamps do not come on
when the parking brake is ap-
plied.<
High steering effort:
Check the fluid level. Refer to
page 148.
High steering effort during sudden tran-
sitions:
Consult your authorized BMW center
immediately for an inspection.Servotronic special
*
If steering becomes lighter as speed in-
creases:
Malfunction in the electronic control
system. Have your BMW center inspect
this system as soon as possible.
If the power steering fails, in-
creased effort will be required to
steer the vehicle.<
If the message "LEVEL CONTROL IN-
ACTIVE" appears in the Check Control,
there is a malfunction in the level con-
trol system.
Stop and inspect the vehicle. If it is
riding significantly lower in the rear
than in the front, or if it is sitting at an
incline (left rear compared to right rear),
consult the nearest authorized BMW
center. Drive with appropriate caution
in the meantime. The vehicle has re-
duced ground clearance or driving
comfort is noticeably reduced.
Even if the attitude of the vehicle is nor-
mal, you should consult the nearest au-
thorized BMW center if the warning
lamp indicates a system fault.

stick. Then push the dipstick into the
reservoir again.
