• For a more precise setting the speed can be
increased in increments of 1 mph (Canada: 1 km/h)
by briefly pulling the control lever in direction (4).
Caution!
If the driver’s foot is not fully removed from the
accelerator pedal, the message “DISTRONIC OVERRIDE”
appears in the multifunction display. The Distronic
control system will be overridden and it will not
regulate the preset vehicle speed and following
distance. The vehicle speed and following distance will
be determined only by the accelerator pedal position.
Invalid attempts to activate
The multifunction display will show “––– MPH” during
invalid attempts to activate Distronic:
• below a speed of approximately 25 mph
(Canada: 30 km/h),
• while the electronic stability program (ESP) is
switched off – ESP warning lamp v in
speedometer dial is illuminated, see page 112,
• by moving the distronic control lever in “RESUME”
direction (4) when no speed is stored in memory,
• during the initialization and self-test phase after the
engine is started – this can take up to 2 minutes,
• while depressing the service brake pedal,
• while the parking brake is set – check ; warning
lamp (Canada: !) in instrument cluster, see
page 112,
• with the gear selector lever in position “P”, “R”
or “N” – check gear range indicator display in
instrument cluster, see page 112.
See page 330 for malfunction and warning messages if
the Distronic is malfunctioning.
Warn ing!
Distronic brakes (up to 20% of vehicle braking
power) the vehicle to restore the preset distance or
to maintain the speed. The brake pedal is
automatically retracted as this happens.
Keep driver’s foot area clear at all times, including
the area under the brake pedal. Objects stored in
this area may impair pedal movement which could
interfere with the braking ability of the Distronic
system.
Do not place your foot under the brake pedal – your
foot could become caught.
