Introduction

CUPRA recommends having the dodge and

turn assistance systems activated except in

the exceptions described in section

Adaptive Cruise Control (ACC) maintains a

constant speed set by the driver. When

approaching another vehicle in front, the

ACC detects it and adapts the speed auto-

matically, maintaining a distance set by

the driver.

●

If the vehicle stops for several minutes.

If a door is opened.

When the turn signal is switched on for over-

taking, the ACC reduces the distance from

the vehicle in front to help with the overtak-

ing manoeuvre. The set cruising speed will

not be exceeded.

WARNING

If the message ACC ready to start is dis-

played on the instrument cluster display

and the vehicle in front moves off, your ve-

hicle will move off automatically. In this

case, any obstacles in the road may not be

detected. This may cause serious accidents

and injuries.
