braking which is applied by the ACC system is limited and can be
overridden by the driver applying the brakes.
If the ACC system predicts that its
maximum braking level will not be
sufficient, an audible warning will
sound while the ACC continues to
brake. This is accompanied by the
heads-up display; a red warning bar
illuminating on the windshield. The driver should takeimmediate
action.
Note:The brakes may emit a sound when they are being modulated by
the adaptive cruise control system.
WARNING:Adaptive cruise control only warns of vehicles
detected by the radar sensor. In some cases there may be no
warning or the warning may be delayed. The driver should always
apply the brakes when necessary. Failing to do so may result in a
collision, serious injury or death.

Disengaging adaptive cruise control
Press the brake pedal to disengage the adaptive cruise control. CRUISE

Overriding adaptive cruise control
WARNING:Whenever the driver is overriding the ACC by
pressing the accelerator pedal, the ACC will not automatically
apply the brakes to maintain separation from any vehicle ahead.
The set speed and gap distance can be overridden by pressing the
accelerator pedal.
When the driver is overriding ACC, the green
cruise indicator light
is illuminated, and CRUISE OVERRIDE is displayed in the message
center. When the accelerator is released, the ACC function will operate
again and vehicle speed will decrease to the set speed, or a lower speed
if following a slower vehicle.
Changing the set speed
There are three ways to change the
set speed:
•Accelerate or brake to the
desired speed and press and
release the SET + or SET –
control
•Increase or decrease the speed by
holding either the SET + or SET
– control, until the desired set
speed is shown on the message
center. The vehicle speed will gradually change to the selected speed.
•Increase or decrease the speed in increments of 1 mph (2 km/h) by
briefly pressing the SET + or SET – control.
The ACC may apply the brakes to slow the vehicle down to the new set
speed. The set speed will display continuously in the message center
while ACC is active.
