TOYOTA SAFETY SENSE™
Toyota Safety Sense™ 2.5+ (TSS 2.5+) is a set of active safety technologies
designed to help mitigate or prevent collisions across a wide range of t\
raffic
situations, in certain conditions. TSS 2.5+ is designed to help support \
the driver’s
awareness, decision making and vehicle operation contributing to a safe \
driving
experience.
Refer to the Owner’s Manual for operation, setting adjustments, limitations and
more details to understand these functions and complete safety precautions. For
more information, please go to www.toyota.com/safety-sense.
Quick overview-Toyota Safety Sense™ 2.5+
Lane Departure Alert with Steering Assist (LDA w/SA)
LDA w/SA is designed to provide notification when the system detects
an unintended lane departure.
The Steering Assist function is designed to provide small corrective
steering inputs to the steering wheel for a short period of time to help\
keep the vehicle in its lane.
The Sway Warning function is designed to detect vehicle swaying
(based on the vehicle location and steering wheel operation) and alert\
drivers with an audio and visual alert, urging them to take a break.
Pre-Collision System with Pedestrian Detection (PCS w/PD)
PCS w/PD is designed to provide alert, mitigation, and/or avoidance
support in certain conditions, when the system detects a potential
collision with a preceding vehicle is likely to occur.
The advanced grille-mounted radar sensor system is designed to
work with the forward-facing camera to help recognize a preceding
pedestrian or bicyclist, and provide an alert, mitigation and/or
avoidance support in certain conditions.
Automatic High Beams (AHB)
AHB is designed to detect the headlights of oncoming vehicles and
the tail lights of preceding vehicles and switch between high beams
and low beams as appropriate.
Road Sign Assist (RSA)
RSA is designed to recognize specific road signs using the forward-
facing camera to provide information to the driver via the display.
Full-Speed Range Dynamic Radar Cruise Control (DRCC)
Full-Speed Range DRCC is designed to help maintain a pre-set
distance to a preceding vehicle when the preceding vehicle is traveling \
at a lower speed. The minimum set speed is approximately 20 MPH,
but once activated, the operating speed range is 0-110 MPH.
Lane Tracing Assist (LTA)
LTA is designed to help keep the vehicle in the center of a lane by
assisting the driver in steering control when using Full-Speed Range
DRCC.

• The area ahead of the vehicle is dark.
• There are no oncoming or preceding vehicles with headlights or tail\
lights turned on.

ly toggles
between high and low beams accordingly.
