has been fastened correctly.
The 'Fasten safety belts' reminder is issued as
long as the driver's safe ty belt has not been fas-
tened. In some country- specific versions, the
'Fasten safety belts' remi nder is also activated
at road speeds above approx. 5 mph or 8 km/h if
the passenger's safety belt is not fastened, if
objects are placed on the passenger seat, or if
driver or passenger unfasten their safety belts.
Damage to safety belts
If the safety belts are damaged or
stressed in an accident: have the belt sys-
tem, including any belt tensioners or child-
restraint systems, replaced and the belt
anchors checked. Have this work done only by
your BMW center or at a workshop that works
according to BMW repair procedures with cor-
respondingly trained perso nnel. Otherwise, it is
not guaranteed that the safety devices will func-
tion properly. <
Mirrors
Exterior mirrors
The passenger's mirror is more convex
than the driver's mirror. The objects seen
in the mirror are closer than they appear. Do not
gauge your distance from traffic behind you on

Parking brake
The concept
Your BMW is equipped with an electromechan-
ical parking brake that can be set and released
by using a button.
The parking brake is primarily used to prevent
the vehicle from rolling when it is parked.
When the vehicle is stationary, the parking
brake acts on the rear wheels via an electrome-
chanical mechanism. When the vehicle is rolling
or being driven, the parking brake acts on the disc brakes of the front and rear wheels via the
hydraulic brake system.
Setting the brake
Pull the button. The parking brake is set.
The indicator lamp in the instrument
cluster and the LED on the button light
up red. The parking brake is set.
Indicator lamp in Canadian models.
To set the parking brake, the remote control
does not need to be in the ignition lock.
While driving
In the rare case that the parking brake needs to
be used while driving, pull the button for a
lengthy period:
The vehicle brakes hard while the button is
being pulled. The indicator lamp in the instrument
cluster lights up red, a sound is issued
and the brake lamps light up.
Indicator lamp in Canadian models.
As soon as you brake the vehicle almost to a
standstill, approx. 2 mph/3 km/h, the parking
brake remains set.
Releasing
Take the remote cont rol with you when
leaving the vehicle so that children, for
example, cannot release the parking brake. <
