WARNING
Observe the safety warnings ››› in Gear
sel
ector positions on page140.
●
Never allow the brake to rub and do not use
the brake pedal too often or for long periods,
as the brakes can overheat. This reduces
the braking power, increases the braking dis-
tance or even causes a brake system fault.
●
If you have to stop on a hill, keep the vehi-
cle’s brakes applied with the brake pedal or
parking brake.
NOTICE
●
If you stop the vehicle on a gradient, do not
att
empt to stop it from rolling by depressing
the accelerator when a gear has been selec-
ted. This could cause overheating and dam-
age the automatic gearbox.
●
If you allow the vehicle to roll with the lever
in position N and the engine o, the auto-
matic gearbox will be damaged by lack of
lubrication.
●
In certain driving situations or trac condi-
tions, the gears could overheat and be dam-
aged! If the warning lamp
lights up, stop
the v
ehicle as soon as you can and wait for
the gearbox to cool ›››page144.
●
If the gearbox operates with the backup
programme, take the vehicle to a specialised
workshop and have the fault repaired with-
out delay.
Kick-down
The kick-down device provides maximum ac-
celeration when the gear selector lever is in the
positionsD, S or in Tiptronic mode.
When the accelerator pedal is pressed right
down, the automatic gearbox will shift down
to a lower gear, depending on road speed
and engine speed. This takes advantage of the
maximum acceleration of the vehicle ›››
.
The upshift t
o the next higher gear is delayed
until the engine reaches maximum rpm.
WARNING
Please note that if the road surface is slip-
pery or w
et, the kickdown feature could
cause the driving wheels to spin, which could
result in skidding.
Launch-control program
The Launch-control programme enables maxi-
mum acceleration from a standstill.
Condition: the engine must have reached oper-
ating temperature and the steering wheel must
not be turned.
The engine speed for Launch-control is dier-
ent for petrol and diesel engines.
To use the Launch-control it is necessary to
disconnect the traction control (TCS) using the
infotainment system menu ›››page35. The
warning lamp
will stay switched on or will
flash sl
owly depending on whether or not the
vehicle has a driver information system.
On vehicles with the driver information system,
the ESC lamp lights up permanently and the
corresponding text message Stability con-
trol deactivated (temporary) appears on
the instrument panel to indicate the deactiva-
tion status.
●
With the engine running, switch o tr
