Electromechanical
parking brake
Operation
The ele ctromechanical parking brake replaces
the hand brake.

> Pull on the switch @ c::> fig. 107 to apply the
parking brake. The indicator light in the
sw itch illuminates .
.,. Step on the brake pedal or the accelerator

light in the sw itch goes out .
Your vehicle is equipped with an electrome chanical parking brake . The parking brake is
designed to p revent the veh icle from rolling
u nintentionally and replaces the hand b rake. .,..
Using the parking brake to perform emer
gency braking will slow your vehicle down
as if you had made a full brake application.
The laws of physics cannot be suspended
even w ith ESP and its associated compo
nents (ABS, ASR, EDS). In corne rs and
when road or weather conditions a re bad,
a full brak e application can cause the vehi
cle to skid or the rear end to break away -
r isking an accident.

These distances may exceed or fa ll short of
these target distances, depending on the driv

Distance 1 ,;;:::::,_,;;:::::, __ _
This setting is ideal for brisk driv ing in bump

of 25 mph (40 km/h) -
a distance of 72 feet (22 meters) at a speed
