When your vehicle is too close to
a vehicle ahead, and sufficient
automatic deceleration via the
cruise control is not possible, the
display will flash and the buzzer
will sound to alert the driver. An
example of this would be if
another driver cuts in front of you
while you are following a vehicle.
Depress the brake pedal to
ensure an appropriate vehicle-to-
vehicle distance.

■

Warnings may not occur when
In the following instances, warnings may not occur even when the
vehicle-to-vehicle distance is small.
● When the speed of the preceding vehicle matches or exceeds

your vehicle speed

● When the preceding vehicle is traveling at an extremely slow

speed

● Immediately after the cruise control speed was set
● When depressing the accelerator pedal

Approach warning (vehicle-to-vehicle distance control mode)

4-5. Using the driving support systems

When constant speed control mode is selected, your vehicle will main-
tain a set speed without controlling the vehicle-to-vehicle distance.
Select this mode only when vehicle-to-vehicle distance control mode
does not function correctly due to a dirty radar sensor, etc.

With the cruise control off,
press and hold the “ON-OFF”
button for 1.5 seconds or more.

Immediately after the “ON-OFF”
button is pressed, the radar cruise
control indicator will come on.
Afterwards, it switches to the cruise
control indicator.
Switching to constant speed con-
trol mode is only possible when
operating the lever with the cruise
control off.

Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 25 mph
[40 km/h]) and push the lever
down to set the speed.

Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the lever is released becomes the
set speed.

■

Dynamic radar cruise control with full-speed range can be set when

●

The shift lever is in D.

●

Vehicle speed is at or above approximately 30 mph (50 km/h).
However, when a preceding vehicle is detected, the dynamic radar cruise
control with full-speed range can be set even if the vehicle speed is at or
below approximately 30 mph (50 km/h).

■

Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicle distance
control mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.

■

When the vehicle stops while follow-up cruising

●

Pushing the lever up while the vehicle ahead stops will resume follow-up
cruising if the vehicle ahead starts off within approximately 3 seconds after
the lever is pushed up.

●

If the vehicle ahead starts off within 3 seconds after your vehicle stops, fol-
low-up cruising will be resumed.

■

Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the fol-
lowing situations:

●

Actual vehicle speed falls at or below approximately 25 mph (40 km/h) when
there are no vehicles ahead.

●

The preceding vehicle leaves the lane when your vehicle is following at a
vehicle speed at or below approximately 25 mph (40 km/h). Otherwise, the
sensor cannot properly detect the vehicle.

●

VSC is activated.

●

TRAC is activated for a period of time.

●

When the VSC or TRAC system is turned off.

●

The sensor cannot detect correctly because it is covered in some way.

●

Pre-collision braking is activated.

●

The parking brake is operated.

●

The vehicle is stopped by system control on a steep incline.

●

The following are detected when the vehicle has been stopped by system
control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes.

If vehicle-to-vehicle distance control mode is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.

WARNING

■

Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Blind Spot Monitor function is a supplementary function which alerts the
driver that a vehicle is present in the blind spot. Do not overly rely on the
Blind Spot Monitor function. The function cannot judge if it is safe to change
lanes, therefore over reliance could cause an accident resulting in death or
serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.
