STARTING AND DRIVING
Gear selector inhibitor
The gear selector inhibitor prevents accidental
changing between different gear positions in an
automatic gearbox.
Automatic gear selector inhibitor
The automatic gear selector inhibitor has special
safety systems.
From park position - P
To be able to move the gear selector from the P
position, the brake pedal must be depressed and
the ignition position must be II.
From neutral position - N
If the gear selector is in the N position and the
car has been stationary for at least 3 seconds
(irrespective of whether the engine is running)
then the gear selector is locked.
To be able to move the gear selector from the N
position to another gear position, the brake pedal
must be depressed and the ignition position must
be II.
Message in the driver display
If the gear selector is inhibited, a message is
shown in the driver display, e.g.
Press brake pedal to activate gear lever
The gear selector is not inhibited mechanically.

Kick-down function
Kick-down is used when maximum acceleration
is needed, such as for overtaking.
When the accelerator pedal is pressed all the
way to the floor (beyond the position normally
regarded as full acceleration) a lower gear is
immediately engaged. This is known as kick-
down.
If the accelerator is released from the kick-down
position, the gearbox automatically changes up.
Safety function
To prevent over-revving of the engine, the gear-
box control program has a protective downshift
inhibitor.
The gearbox does not permit downshifting/kick-
down which would result in an engine speed high
enough to damage the engine. Nothing happens
if the driver still tries to shift down in this way at
high engine speed – the original gear remains
engaged.
On kick-down the car can shift down one or more
steps at a time, depending in engine speed. The
car shifts up when the engine has reached is
maximum engine speed in order to prevent
Gear lever
engine damage.

Gear shift indicator*
The gear shift indicator in the driver display
shows the current gear during manual gearshift-
ing and when it is appropriate to engage the
next gear for optimum fuel economy.
For eco-driving during manual gear changing, it is
important to drive in the right gear and to change
gear in good time.
The gear shift indicator shows the current gear in
the driver display and uses an up arrow to indi-
cate when shifting to a higher gear is recom-
mended. The gear shift indicator is shown in gear
position B.
