Hill descent assist brakes all four whee ls auto-
matically in order to limit speed when driving ei-
ther forwa rd or reverse on hills with a grade up to
approx imately 50%.
When the hill descent assist is on, the current
driving speed, when your vehicle entered t he in-
cline is maintained.
It is only possible to switch
on the assist when driving slower than 37 mph
(60 km/h). The assist works between approxi-
mately 2 and 19 mph (4 and 30 km/h) . The driver
can increase or decrease the vehicle speed within
these limits by depressing the accelerator or
brake pedal In addition, vehicle steerability is in-
creased due to the braking distribution when
driving in reverse.

- the diode in the button ill uminates,
- vehicle speed is below approximately 19 mph
(30 km/h)
- the incl ine is 10%.
