Using the GAIN (+/-) selection
buttons, set a starting gain of
5.0.
While driving 20 - 25 mph [35 - 40 km/h], fully apply the
manual
TRAILER BRAKE OUTPUT
slider.
Adjust the gain setting, using t he GAIN (+/-) selection buttons , to
either increase or decrease to j ust below the point of trailer wheel
lock-up.
For confirmation, repeat steps and until desired gain setting
is reached (just below point of trailer wheel lock-up).
■ When using the trailer brake control system
Please turn off the intuitive parking assist while towing a tra iler. If left on,
sonar sensors will detect the trailer being towed.
■ When setting the gain

5508-2. Steps to take in an emergency
*1: Driver’s seat belt buzzer:The driver’s seat belt buzzer sounds to alert the driver that h is or her seat
belt is not fastened. Once the engine switch is turned to the “ ON” or
“START” position, the buzzer sounds for 6 seconds. If the vehic le reaches
a speed of 12 mph (20 km/h), the buzzer sounds once. If the sea t belt is
still unfastened after 30 seconds, the buzzer will sound intermittently for 10
seconds. Then, if the seat belt is still unfastened, the buzzer will sound in a
different tone for 20 more seconds.
PCS warning light (If equipped)
When the warning light flashes:
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. 226)
• Radar sensor or camera sensor operational conditions (such as temperature, etc.) being not met
 Driving is possible in this case. The PCS (Pre-Colli-
sion System) will be enabled if the operational condi-
tions (such as temperature, etc.) are met again.
• 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. 235, 304)
