uuWhen Driving uAdaptive Cruise Control (ACC)*
Driving
Adaptive Cruise Control (ACC)*
Helps maintain a constant vehicle speed and a set following-distance behind a
vehicle detected ahead of yours, without you having to keep your foot on the brake
or the accelerator.
When ACC slows your vehicle by applying the brakes, your vehicle’s brake lights will
illuminate.1 Adaptive Cruise Control (ACC)*
Important Reminder
As with any system, there are limits to ACC. Use the
brake pedal whenever necessary, and always keep a
safe distance between your vehicle and other vehicles.
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when travelling on open
highways in good weather.
3WARNING
ACC has limited braking capability.
When your vehicle speed drops below
22 mph (35 km/h), ACC will
automatically cancel and no longer will
apply your vehicle’s brakes.
Always be prepared to apply the brake
pedal when conditions require.
When to use
■Vehicle speed for adaptive cruise co ntrol: Desired speed in a range above
roughly 25 mph (40 km/h) ~
The camera is located
behind the rearview mirror.
■Shift positions for adaptive cruise control: In (

uuWhen Driving uLane Departure Warning (LDW)*
Continued
Driving
Lane Departure Warning (LDW)*
Alerts you when the system determines a possibility of your vehicle unintentionally
crossing over detected lane markings.
If your vehicle is getting too close to detected
left or right side lane markings without a turn
signal activated, LDW will give audible and
visual alerts.
The beeper sounds and the Lane Departure
message appears on the multi-information
display, letting you know that you need to
take appropriate action.
The system begins to search for lane mark ings when all the following conditions are
met:
• The vehicle is traveling between about 45 and 90 mph (72 and 145 km/h).
• The vehicle is on a straight or slightly curved road.
• The turn signals are off.
• The brake pedal is not depressed.
• The wipers are not in continuous operation.
■How the System Works
1Lane Departure Warning (LDW)*
Important Safety Reminder
Like all assistance systems, LDW has limitations.
Over-reliance on LDW may result in a collision. It is
always your respons ibility to keep the vehicle within
your driving lane.
LDW only alerts you when lane drift is detected
without a turn signal in us e. LDW may not detect all
lane markings or lane departures; a ccuracy will vary
based on weather, speed and lane marker condition.
It is always your responsibility to safely operate the
vehicle and avoid collisions.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera
