maximum engine speed is reached, unless you have activated the

sport function ⇒ page 90.

If you select a lower gear, the R tronic gearbox will not shift down

until there is no risk of overrevving the engine.

You can change over to automatic mode at any time ⇒ page 92.

WARNING

• The driver should never get out of the vehicle when the engine

is running and a gear is engaged. If you have to leave your vehicle

while the engine is running, you must apply the parking brake and

engage neutral gear (N).

• If the engine is running and a gear is engaged, you will need to

hold the car with the footbrake.

• Do not press the accelerator while selecting a gear with the

vehicle stationary and the engine running, as this could cause an

accident.

• To avoid rolling back on gradients always hold the vehicle with

the footbrake if you have to stop. Never attempt to hold the vehicle

with the clutch when stopping on a gradient. The clutch is disen-

gaged automatically if it is overloaded and becomes too hot - acci-

dent risk! Before the clutch is disengaged, the vehicle will jolt and

the driver information system will display a warning that the

clutch is overloaded.

• Before you drive down a steep gradient, reduce the speed and

use the R tronic to select a lower gear.

• Never allow the brake to drag and do not use the brake pedal

too often or for long periods. Constant braking will cause the

brakes to overheat and will considerably reduce the effectiveness

of the brakes. It will increase the braking distance and could cause

the brake system to fail.

Applies to vehicles: with R tronic

Automatic mode

The gearbox changes the forward gears up and down

automatically.

Driving away from a standstill

– Press and hold the brake pedal.

– Briefly push the selector lever towards position A.

– Release the brake and press the accelerator ⇒ in

“Manual mode” on page 91.

In some situations (such as when driving on mountain roads) it can

be advantageous to switch temporarily to the manual shift

programme ⇒ page 91, so that the gear ratios can be selected

manually to suit the driving conditions.

Applies to vehicles: with R tronic

Kick-down feature

When the accelerator pedal is pressed right down past the point of

resistance at full throttle, the R tronic gearbox will shift down to a

lower gear, depending on road speed and engine speed. The upshift

to the next higher gear is delayed until the engine reaches

maximum rpm. This does not apply if you have activated the sport

function.

WARNING

Please note that if the road surface is slippery or wet, the kick-

down feature could cause the driving wheels to spin, which could

result in skidding.
