Manual release of the selector lever
Fig.103 Sel
ector lever: manual release from
position P.
In the event of a power failure when starting
(e
.g. discharged battery), the lever will remain
locked in position P. To move it to position N
to move the vehicle, there is an emergency re-
lease device under the centre console, on the
right side. Releasing the selector lever requires
a certain degree of practical skill.
Removing the cover from the selector lever:
●
Connect the electronic parking brake ›››
.
●
Carefully pull the corners of the selector lever
boot and twist it up
wards over the lever handle.
Releasing the selector lever:
●
Using the flat part of a screwdriver, press the
yellow tab sideways and keep it pressed down
›››Fig.103.
●
Press the lock button on the selector
lever and move it to positionN.
●
After completing the emergency release, re-
attach the selector lever boot to the gearbox
console.
WARNING
Do not move the lever from position P if the
parking br
ake is not firmly engaged. If you
still think the car could move, press the brake
pedal. Danger! The vehicle could move in an
unforeseen way and cause an accident or
serious injury.
Driving on slopes
Hill Hold Control (HHC)
When driving up a slope or driving in Oroad
with the lever in position D/S, stopping the vehi-
cle switches on the hill hold control.
When the brake pedal is released, the assistant
keeps the vehicle’s brakes applied for a few
seconds to give the driver time to press the ac-
celerator pedal and continue driving.
downhill assistant
Downhill speed control is activated when the
gear lever is in the D/S position and the brake is
applied. An appropriate lower gear is engaged.
The assistant attempts to maintain the speed
at which the vehicle was travelling when the
brake was applied, within logical limits. It may
be necessary to correct the speed by pressing
the brake.
The assistant can only change down as far as
3rd gear. It is possible that on very steep slopes
you may have to switch to tiptronic mode and
thus manually change down to 2nd or 1st gear
to take advantage of engine braking and take
the load o the brake system.
Downhill speed control is deactivated as soon
as the road levels out again or you press the
accelerator pedal.
On vehicles with a cruise control system
›››page158, downhill speed control is activa-
ted when you set a cruising speed.
WARNING
The downhill speed control cannot defy the
l
aws of physics. Therefore, speed cannot be
maintained constant in all situations. Always
be prepared to use the brakes!
Hill Descent Control (HDC)
✓ Valid for vehicles: 4Drive all-wheel drive
Hill Descent Control limits the speed on steep
descents by automatically braking all four
wheels, both when moving forward and in re-
verse. As the anti-lock brake system remains
active, it prevents the wheels from locking.
