Limitations Of The Adaptive Cruise Control - Volvo XC90 TWIN ENGINE Owner's Manual

Cessation of automatic braking
In some situations, automatic braking ceases on
reaching 0 km/h and Adaptive Cruise Control is
set in standby mode. This means that the brakes
are released and the car may start to roll - the
driver must therefore intervene and brake the car
himself/herself to keep it stationary.
This may take place in the following situations:
•
the driver puts his/her foot on the brake
pedal
•
the parking brake is applied
•
the gear selector is moved to P, N, or R posi-
tion
•
the driver sets the adaptive cruise control in
the standby mode.
Automatic activation of parking brake
In certain situations the parking brake is applied
to keep the car stationary.
This takes place if the adaptive cruise control is
holding the car stationary with the foot brake and:
•
the driver opens the door or takes off his/her
seatbelt
•
ACC has kept the car stationary for more
than approx. 5 minutes
•
the brakes have overheated
•
the engine is switched off.

Limitations of the adaptive cruise
control*
The (Adaptive Cruise Control - ACC) may have
limitations in certain situations.
Steep roads and/or heavy load
Bear in mind that the adaptive cruise control is
primarily intended for use when driving on level
road surfaces. The function may have difficulty in
keeping the correct distance from the vehicle
ahead when driving on steep downhill slopes - in
which case, be extra attentive and ready to brake.
Do not use the adaptive cruise control with a
heavy load or with a trailer connected to the car.
Miscellaneous
•
Off Road
Drive mode cannot be selected
when the adaptive cruise control is activated.
NOTE
The function uses the car's radar unit, which
has some general limitations, see the "Limita-
tions for radar unit" section.
