Rocking the vehicle
Rocking the vehicle by shifting between
drive position D and reverse gear R can
help free a vehicle stuck in mud or snow.
The engine control system of this vehicle
electronically limits shifting between drive
position D and reverse gear R to very low
speeds, i.e. approx. 5 mph (9 km/h). To
shift between drive position D and reverse
gear R, move the gear selector lever past
the resistance point up or down.
Working on the vehicle
Hill start assist system
On uphill grades with a gradient angle of
more than 5°, the hill start assist system
maintains the pressure in the brake sys-
tem for approximately 1 second after you
have released the brake pedal. Therefore,
you can start off smoothly without the
vehicle moving immediately after releasing
the brake pedal.
The hill start assist system is inactive
ț when starting off on a level road or
downhill grades
ț with the transmission in neutral
position N
ț with the parking brake set
ț if the ESP
®
has switched off due to a
malfunction
Warning! G
When working on the vehicle, set the
parking brake and shift to park position P.
Otherwise the vehicle could roll away.
Warning! G
The hill start assist system is not designed
to function as a parking brake and does not
prevent the vehicle from moving when
parked on an incline.
Always set the parking brake in addition to
shifting to park position P.
