Adaptive Cruise Control
42
xIf your vehicle no longer detects the vehicle
in front
The vehicle gradually accelerates back to
the set target vehicle speed and will drive at
that constant speed.
If a vehicle in front is detected while
accelerating to the set target vehicle speed,
vehicle tracking will be started again.
CAUTION
If the driver operates the brake pedal during automatic braking, the pedal
may feel stiff; however, this is not a malfunction. By depressing the brake
pedal further you can apply more braking force. When the brake pedal is
released it will return to its original condition.
NOTE
xWhen the brakes are applied by Adaptive Cruise Control, the vehicle’s
brake lights will illuminate.
xEven if there is no lead vehicle present, on a downhill grade, the Adaptive
Cruise Control’s automatic brake may operate in order to maintain the set
target vehicle speed.
xSome noises may be audible during automatic braking. This is caused by
the braking control and does not indicate a malfunction.
xTo temporarily accelerate quickly, use the accelerator pedal. After acceler-
ating, the vehicle will gradually return to the set target vehicle speed shown
in the gauge cluster.
xThere are cases where the vehicle in front has turned off the road while
your vehicle is still controlled by the automatic braking operation that has
activated due to the deceleration of the vehicle in front of yours. In those
cases, the brake will be automatically released gradually. Depress the
accelerator pedal if necessary.
xThe lead-vehicle tracking function has the following characteristics:
- If the lead vehicle’s brake lamp is detected, deceleration is started more
quickly than without detection.
- If the vehicle moves to the fast lane while traveling more than 37 MPH
(60 km/h), the system starts acceleration to the set vehicle speed more
quickly because it is linked with the turn signal.

Lane Departure Warning
60
CAUTION
In the following situations, the Lane Departure Warning will or may not acti-
vate:
xVehicle speed is approximately 30 MPH (50 km/h) or less.
xWhen the steering wheel is turned significantly to either side
xWhen the vehicle is driving around a curve whose radius is 0.18 miles (300
m) or smaller.
xWhen the brake pedal is depressed or immediately after it is depressed
xWhen the accelerator pedal is almost fully depressed and the vehicle is
accelerating or immediately after accelerating
xWhen the following distance behind a vehicle in front is short
xWhile the turn signal is operating and for approximately 4 seconds after the
turn signal lever has returned to its original position
xFor approximately 4 seconds after the hazard lamp has switched off
xWhen the vehicle has not returned to the inside of the lane after the Lane
Departure Warning has activated
xThe lane is narrow.
xWhen it is difficult for the camera to detect lane markings
- There are no lane markings or they are very worn.
- The lane markings are yellow.
- It is difficult to detect lane markings as they are similar in color to the
road surface.
- The lane markings are narrow.
NOTE
xThe following situations may cause incorrect lane detection and a faulty
Lane Departure Warning to occur.
- Tire tracks on a wet road or snow-covered road
- Boundaries between snow and asphalt, marks from road repair, etc.
- Shadows of guardrails
- Lane markings are drawn in double
- There are some lane markings left from roadwork or markings from the
previous road.
xWhen the Lane Departure Warning OFF indicator light is illuminated, the
Lane Departure Warning is inactive.
