Warning
ACP is an emergency crash
preparation feature and is not
designed to avoid crashes. Do
not rely on ACP to brake the
vehicle.
ACP may not:
Respond to stopped vehicles,
pedestrians, or animals.
Detect a vehicle ahead on
winding or hilly roads.
Detect a stopped or
slow-moving vehicle or other
object ahead.
Detect a vehicle when
weather limits visibility, such
as in fog, rain, or snow. In
these situations, ACP sensor
performance is limited.
(Continued)
Warning (Continued)
Complete attention is always
required while driving, and you
should be ready to take action
and apply the brakes and/or steer
the vehicle to avoid crashes.
Brake Preparation
When quickly approaching a vehicle
ahead, Brake Preparation reduces
brake response time by having the
brake system prepared for driver
braking to occur more rapidly.
Automatic Braking
In some imminent front-end crash
situations, if the driver has not
applied the brakes, Automatic
Braking applies the brakes to help
reduce crash damage. It may even
help avoid some very low speed
crashes.
Automatic Braking may slow the
vehicle to a complete stop to try to
avoid a potential crash. If this
Driving and Operating
happens, Automatic Braking will
engage the Electric Parking Brake
(EPB) to hold the vehicle at a stop.
To release the EPB, press the EPB
button. A firm press of the
accelerator pedal will also release
Automatic Braking and the EPB.
Warning
Automatic Braking may
automatically brake the vehicle in
situations where it may be
unnecessary. It could respond to
a turning vehicle ahead,
guardrails, signs, and other
non-moving objects. This could
be uncomfortable and startling. To
override Automatic Braking, firmly
press the accelerator pedal, if it is
safe to do so.
Automatic Braking can be disabled
or reduced through vehicle
personalization. See the Auto
Collision Preparation portion of
9-57
