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. approximately 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 electronic parking brake en-
gaged
ț if the ESP ® has switched off due to a
malfunction
Warning!
G
When working on the vehicle, engage the
electronic 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 an electronic parking brake
and does not prevent the vehicle from mov-
ing when parked on an incline.
Always engage the electronic parking brake
in addition to shifting to park position P.
