■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving,
the daytime running lights turn on automatically whenever the engine is
started and the parking brake is released with the headlight switch in the
/ / position. (Illuminate brighter than the parking lights.)
Daytime running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
switch.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor
■ Automatic light off system
Vehicles without a smart key system
● When the headlights are on: The headlights and tail lights turn off 30 sec-
onds after the engine switch is turned to the “ACC” or “LOCK” position and a
door is opened and closed. (The lights turn off immediately if on the
key is pressed after all the doors are locked.)
● When only the tail lights are on: The tail lights turn off automatically if the
engine switch is turned to the “ACC” or “LOCK” position and the driver’s
door is opened.
To turn the lights on again, turn the engine switch to “ON” position, or turn the
light switch to or once and then back to or .
If any of the doors is kept open, the lights automatically turn off after 20 min-
utes. The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

■Dynamic radar cruise control with full-speed range can be set when
● The shift lever is in D.
● Vehicle speed is 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.
■ Automatic cancelation of vehicle-t o-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the fol-
lowing situations.
● Actual vehicle speed falls 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 below approximately 25 m ph (40 km/h). Otherwise, the sen-
sor 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 by pressing the VSC off switch.
● 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.

*
*
: Depending on the conditions, detection of a vehicle and/or object may
occur.
■ Conditions under which the RCTA function may not function correctly
●The RCTA function may not detect vehicles correctly in the following situa-
tions:
• When the sensor is misaligned due to a strong impact to the sensor or its
surrounding area
• When mud, snow, ice, a sticker, etc., is covering the sensor or surround- ing area on the rear bumper
• When driving on a road surface that is wet with standing water during bad weather, such as heavy rain, snow, or fog
• When multiple vehicles are approaching with only a small gap between
each vehicle
• When a vehicle is approaching at high speed
●
Vehicles that the sensors cannot detect
due to obstructions

• Immediately after the engine is started with the RCTA function is set to on • When backing up on a slope with a
sharp change in grade
• When backing out of a shallow angle parking spot
• When the sensors cannot detect a vehicle due to obstructions

(Yellow)
Brake system warning lightIndicates a malfunction in the electric parking brake
→ Have the vehicle inspected by your Toyota dealer
immediately.
PCS warning light
When the warning light flashes (and a buzzer sounds):
Indicates a malfunction in the PCS (Pre-Collision System)
→ Have the vehicle inspected by your Toyota dealer
immediately.
When the warning light illuminates:
Indicates that the PCS (Pre-Collision System) is temporar-
ily unavailable, possibly due to either of the following:
• An area around the radar sensor or camera sensor being dirty or covered with condensation, ice, stickers,
etc.
→ Clear the dirt, condensation, ice, stickers, etc.
(→P. 206, 207)
• Radar sensor or camera sensor operational conditions (such as temperature, etc.) being not met
→ Driving is possible in th is case. The PCS (Pre-Colli-
sion System) will be enabled if the operational condi-
tions (such as temperature, etc.) are met again.
When the warning light is illuminated:
• Either the VSC (Vehicle Stability Control) system or PCS (Pre-Collision System) is disabled or both are disabled.
→ To enable the PCS, enable both the VSC system and
PCS. ( →P. 215, 281)
