STARTING AND OPERATING 125
(Continued)
NOTE:
If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or accelerate
(not to exceed the original set speed) auto-
matically to maintain a preset following
distance, while matching the speed of the
vehicle ahead.
Any chassis / suspension or tire size modifi-
cations to the vehicle will affect the perfor-
mance of the Adaptive Cruise Control and
Forward Collision Warning system.
NOTE:
Cruise Control will not detect vehicles directly
ahead of you. Always be aware of the mode
selected Ú page 395.
WARNING!
Adaptive Cruise Control (ACC) is a conve-
nience system. It is not a substitute for
active driver involvement. It is always the
driver’s responsibility to be attentive of road,
traffic, and weather conditions, vehicle
speed, distance to the vehicle ahead; and,
most importantly, brake operation to ensure
safe operation of the vehicle under all road
conditions. Your complete attention is
always required while driving to maintain
safe control of your vehicle. Failure to follow
these warnings can result in a collision and
death or serious personal injury.
The ACC system:
Does not react to pedestrians,
oncoming vehicles, and stationary
objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance
conditions.
Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
Will bring the vehicle to a complete stop
while following a target vehicle and hold
the vehicle for 2 seconds in the stop
position. If the target vehicle does not
start moving within two seconds the
ACC system will display a message that
the system will release the brakes and
that the brakes must be applied manu-
ally. An audible chime will sound when
the brakes are released.
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 construc-
tion 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.
When towing a trailer up or down steep
slopes.
When circumstances do not allow safe
driving at a constant speed.
