•
During wheel spin or wheel lock-up.
•
If the vehicle's speed is increased by using
the accelerator pedal for more than 1 minute.
•
Engine speed (rpm) is too high or too low.
The currently set speed will be saved in the sys-
tem's memory.

control by pressing 0. The saved speed is shown
in brackets in the information display.

Adaptive Cruise Control –
introduction
ACC is an optional system designed to assist
the driver by maintaining a set speed or a set
time interval to the vehicle ahead. It is primarily
intended for use on long straight roads in steady
traffic, such as on highways and other main
roads.
When the driver has set the desired speed and
the time interval to the vehicle ahead, ACC func-
tions as follows:
•
If there are no other vehicles in the lane
ahead of you, your vehicle will travel at the
set speed.
•
If ACC's radar sensor detects a slower mov-
ing vehicle in the lane ahead, the system will
adapt your vehicle's speed to help maintain
the set time interval to the vehicle ahead.
When there are no longer slower moving
vehicles ahead, your vehicle will accelerate to
resume the set speed.
If ACC is switched off completely or in standby
mode and your vehicle comes too close to
another vehicle ahead, the driver will be warned
by the Distance Alert system (see Distance Alert
– introduction (p. 198)).
