transmission (Y page 173).
The shift range selected is shown in the

transmission shifts only as far as the selected
gear. Driving situations 000B
You can use the engine's braking

000E
The braking effect of the engine can
be utilized on downhill gradients or
when driving:
R
on steep mountain roads
R in mountainous terrain
R in arduous conditions 0014
The braking effect of the engine can
be utilized on extremely steep
downhill gradients and long
downhill stretches.
Restricting the shift range
X
Pull the left-hand steering wheel paddle
shifter.
The automatic transmission shifts down
one gear and restricts the shift range to the
relevant gear.
i If the engine exceeds the maximum
engine speed when shifting down, the
automatic transmission protects against
engine damage by not shifting down.
i If the maximum engine speed for the shift
range is reached and you continue to
accelerate, the automatic transmission
shifts up, even if the shift range is
restricted. This prevents the engine from
overrevving.
Derestricting the shift range X
Pull the right-hand steering wheel paddle
shifter.
The shift range is derestricted. 174
