Going down slopes with the speed limiter

page 222 flashes and
an audible warning may sound. Brake and
change down a gear.
Temporarily deactivate by pressing the ac-
celerator down
If the accelerator is pressed right down (kick-
down) and the set speed is exceeded be-
cause driver wishes to do so, the limiter is
temporarily disabled.
To confirm it being switched off an acoustic
signal sound once. While cruise control is
off, the control lamp flashes
.
When the accelerator is no longer pressed
down and the speed is reduced below the
set value, the limiter switches on again. The
control lamp will light up and remain lit.
Automatic off
The speed limiter is automatically switched
off:
●
If the system detects a fault that could
negatively affect the working order of the
limiter.
●
If the airbag is triggered.
WARNING
After use, switch off the speed limiter to
prevent the speed being regulated without
it being required.
●
The speed limiter does not relieve the
driver of their responsibility to drive at the
appropriate speed. Do not drive at high
speed if not necessary.
●
Using the speed limiter in adverse weath-
er conditions is dangerous and can cause
serious accidents. Use the speed limiter
only when the condition of the road surface
and the weather and traffic conditions al-
low it.
●
When driving on a steep gradient, the
speed limiter cannot limit the vehicle’s
speed. This can increase. In this case, brake
and change down a gear.
CAUTION
For automatic switching off due to system
failures, for security reasons, the limiter is
only completely switched off when the
driver stops pressing the accelerator or
consciously switches it off.
Note
●
Different versions of the instrument pan-
el are available and therefore the versions
and instructions on the display may vary.
●
If the cruise control (GRA), the adaptive
cruise control (ACC) or the speed limiter
are connected when the ignition is switch-
ed off, the assistants will switch it when the
ignition is switched on, but only the speed
limiter will maintain the last programmed
speed.
