WARNING!
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situations
(i.e., in highway construction zones).
• When entering a turn lane or highway off ramp;
when driving on roads that are winding, icy,
snow-covered, slippery, or have steep uphill or
downhill slopes; and when towing a trailer.
• When circumstances do not allow safe driving at a
constant speed.
Failure to follow these warnings can result in an
accident or serious personal injury.
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 169
The Cruise Control system has two control modes:
• Adaptive Cruise Control mode for maintaining an
appropriate distance between vehicles.
• Normal (fixed speed) cruise control mode for cruising
at a constant preset speed. For additional information,
refer to "Normal (Fixed Speed) Cruise Control Mode"
in this section. Note: The system will not react to
preceding vehicles. Always be aware of the mode
selected.
You can change the mode by using the Cruise Control
buttons. The two control modes function differently.
Always confirm which mode is selected.
