4RUNNER (U)
WARNING
■Before using LDA system
Do not rely solely upon the LDA system. The LDA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigu ed, such as
from driving for a long period of time.
Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
■ To avoid operating LDA system by mistake
When not using the LDA system, use the LDA switch to turn the system off.
■ Situations unsuitable for LDA system
Do not use the LDA system in the following situations.
The system may not operate properly and lead to an accident, re sulting in
death or serious injury.
● A spare tire, tire chains, etc. are equipped.
● Objects or patterns that could be mistaken for white (yellow) l ines are
present on the side of the road (guardrails, curbs, reflective poles, etc.).
● Vehicle is driven on a snow-covered road.
● White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
● Asphalt repair marks, white (yellow) line marks, etc. are prese nt due to
road repair.
● Vehicle is driven in a temporary lane or restricted lane due to construction
work.
● Vehicle is driven in a construction zone.
■ Preventing LDA system malfunctions and operations performed by
mistake
● Do not modify the headlights or place stickers, etc. on the sur face of the
lights.
● Do not modify the suspension etc. If the suspension etc. needs to be
replaced, contact your Toyota dealer.
● Do not install or place anything on the hood or grille. Also, d o not install a
grille guard (bull bars, kangaroo bar, etc.).
● If your windshield needs repairs, contact your Toyota dealer.

4RUNNER (U)
This mode employs a radar sensor to detect the presence of vehi cles
up to approximately 320 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 traveling 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 fr om closing in on the vehicle ahead.
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The syst em then
returns to constant speed cruising.

WARNING
■To ensure the system can operate properly
Blind Spot Monitor sensors are installed behind the left and ri ght sides of the
rear bumper respectively. Observe the following to ensure the Blind Spot
Monitor can function correctly.
● Do not subject a sensor or its surrounding area on the rear bumper to a
strong impact.
If a sensor is moved even slightly off position, the system may malfunction
and vehicles may not be detected correctly. In the following si tuations,
have your vehicle inspected by your Toyota dealer.
• A sensor or its surrounding area is subject to a strong impact .
• If the surrounding area of a sensor is scratched or dented, or part of them has become disconnected.
● Do not disassemble the sensor.
● Do not attach stickers or install accessories to the sensor or surrounding
area on the rear bumper.
● If a sensor or the rear bumper needs to be removed/installed or replaced,
contact any authorized Toyota retailer or Toyota authorized rep airer, or any
reliable repairer.
● Do not modify the sensor or surrounding area on the rear bumper .
● Do not paint the rear bumper any color other than an official Toyota color.
●Keep the sensors and the surrounding
areas on the rear bumper clean at all
times.
If a sensor or its surrounding area on
the rear bumper is dirty or covered with
snow, the Blind Spot Monitor may not
operate and a warning message ( P.
282) will be displayed. In this situation,
clear off the dirt or snow and drive the
vehicle with the operation conditions of
the Blind Spot Monitor ( P. 286) satis-

WARNING
■When the TRAC/VSC/Trailer Sway Control is activated
The slip indicator light flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular car e when the
indicator light flashes.
■ When TRAC/VSC/Trailer Sway Control systems are turned off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As these are systems to help ensure vehicle stability and driving
force, do not turn the TRAC/VSC/Trailer Sway Control systems off unless
necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, Multi Terrain ABS, TRAC, VSC and Trailer Sway Control will not
function correctly if different tires are installed on the vehi cle.
Contact your Toyota dealer for further information when replaci ng tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspensio n will affect
the driving assist systems, and may cause a system to malfunction.
■ Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situ-
ations.
Depending on many factors such as the conditions of the vehicle, trailer,
road surface and driving environment, the Trailer Sway Control system may
not be effective. Refer to your trailer owner’s manual for info rmation on how
to tow your trailer properly.
■ If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
● Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer sway by turning the steering whee l.
● Begin releasing the accelerator pedal immediately but very grad ually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. ( P. 202)
