• When the part of the windshield in front of the camera sensor is fogged
up or covered with condensation or ice
(Defogging the windshield:
P. 352)
• If the camera sensor is obstructed, such as when the hood is open or a sticker is attached to the windshield near the camera sensor
● If the PCS warning light continues to flash or remains illuminated or the
warning message does not disappear even though the vehicle has returned
to normal, the system may be malfunctioning. Have the vehicle inspected by
your Toyota dealer immediately.

2644-5. Using the driving support systems
When driving on highways and freeways with white (yellow) lines , this
function alerts the driver when the vehicle might depart from i ts lane
and provides assistance by opera ting the steering wheel to keep the
vehicle in its lane.

WARNING
■Before using dynamic radar cruise control with full-speed range
● Driving safely is the sole responsibility of the driver. Do not rely solely on
the system, and drive safely by always paying careful attention to your sur-
roundings.
● The dynamic radar cruise control with full-speed range provides driving
assistance to reduce the driver's burden. However, there are li mitations to
the assistance provided.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be correctly detecting the vehicle ahe ad:
P. 286
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 287
● Set the speed appropriately depending on the speed limit, traff ic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.
● Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condition
observed by the driver. Therefore, the driver must always remai n alert,
assess the danger of each situation and drive safely. Relying on this sys-
tem or assuming the system ensures safety while driving can lea d to an
accident, resulting in death or serious injury.
● Switch the dynamic radar cruise control with full-speed range o ff using the
cruise control main switch when not in use.

WARNING
■Situations unsuitable for dynamic radar cruise control with ful l-speed
range
Do not use dynamic radar cruise control with full-speed range in any of the
following situations.
Doing so may result in inappropriate speed control and could ca use an acci-
dent resulting in death or serious injury.
● Roads where there are pedestrians, cyclists, etc.
● In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered with rain, ice or snow
● On steep downhills, or where there are sudden changes between s harp up
and down gradients
Vehicle speed may exceed the set speed when driving down a stee p hill.
● At entrances to freeways and highways
● When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
● When there is rain, snow, etc. on the front surface of the radar sensor or
camera sensor
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● During emergency towing
● When an approach warning buzzer is heard often

2784-5. Using the driving support systems
This mode employs a radar sensor to detect the presence of vehi cles
up to approximately 328 ft. (100 m) ahead, determines the curre nt
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when travel ing on long
downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-ve hicle dis-
tance switch.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate su ffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+ RES” switch or depressing the accelerator pedal will resume follow-up
cruising.

2844-5. Using the driving support systems
When constant speed control mode is selected, your vehicle will main-
tain a set speed without controllin g the vehicle-to-vehicle distance.
Select this mode only when vehic le-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 cruise con-
trol main switch for 1.5 seconds
or more.
Immediately after the switch is
pressed, the dynamic radar cruise
control indicator will come on.
Afterwards, it switches to the cruise
control indicator.
Switching to constant speed control mode is only possible when operating
the switch 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 press the “- SET”
switch to se t the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the switch is released becomes the
set speed.
