Active TRAC, VSC, Trailer Sway Control, hill-start assist control and
VGRS
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the Multi Terrain ABS is acti-
vated.
• The brake pedal may move down slightly after the Multi Terrain ABS is
activated.
■Hill-start assist control is operational when
●The shift lever is in “D” or “S”.
●The brake pedal is not depressed.
■VGRS is disabled in the following situations
●During stopping or the steering wheel has been moved for a long time
while driving at lower speeds.
●After the engine is restarted at less than -22F (-30C).

CAUTION
■When the VSC and Trailer Sway Control are activated
The slip indicator light flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator light flashes.
■Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the speci-
fied tire pressure level.
The Multi Terrain ABS, Active TRAC, VSC and Trailer Sway Control will not
function correctly if different tires are fitted on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the 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 sys-
tem may not be effective. Refer to your trailer owner’s manual for information
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 swaying by turning the steering wheel.
●Begin releasing the accelerator pedal immediately but very gradually 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. 329)

Pre-Collision System
: If equipped
When a frontal collision seems likely, the system attempts to lessen
vehicle’s damage. Two types of pre-collision system are available.
The brake-linked pre-collision system operates in conjunction with
the braking operation of the driver. The radar type pre-collision sys-
tem has a sensor that is used to detect an unavoidable frontal colli-
sion.
■Pre-collision seat belts (front seats only)
Brake-linked pre-collision system
Based on the speed and amount of the driver’s braking operation, the
system determines if emergency braking is being performed. If this
determination is made, the seat belts are immediately retracted to
increase the effectiveness of the pretensioners (P. 80). In addition,
the system also operates if the driver loses control of the vehicle.
Radar type pre-collision system
If the pre-collision sensor detects that a collision is unavoidable, the
pre-collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. (P. 80)
However, when the VSC system is disabled, the system will not oper-
ate in the event of skidding.
■Pre-collision brake assist (Radar type only)
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is
depressed.

LC200_OM_OM60F57U_(U)
■Obstacles not detected (Radar type only)
The sensor cannot detect plastic obstacles such as pylons. There may also
be occasions when the radar sensor cannot detect pedestrians, animals,
bicycles, motorcycles, trees, or snowdrifts.
■The pre-collision system is operational when
●Pre-collision seat belts (situation 1)
• Vehicle speed is greater than about 4 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 19 mph (30 km/h).
• The front occupants are wearing a seat belt.
●Pre-collision seat belts (situation 2)
• Vehicle speed is greater than about 19 mph (30 km/h).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
●Pre-collision brake assist
• Vehicle speed is greater than about 19 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 19 mph (30 km/h).
• The brake pedal is depressed.

■Conditions that may trigger the system even if there is no possibility of
collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface (nose up, nose down)
●When passing an oncoming vehicle on a left-turn
●When your vehicle rapidly closes on the vehicle in front
●When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle’s line of travel
●When climbing a steep hill causes an overhead billboard or other metallic
structure to appear directly in the vehicle’s line of travel
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
●When passing through certain toll gates
●When passing through an overpass
When the system is activated in the situations described above there is also
a possibility that the seat belts will retract quickly and the brakes will be
applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten.
■When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (P. 606, 617)

NOTICE
■To prevent the water damage
Take all necessary safety measures to ensure that water damage to the
engine or other components does not occur.
●Water entering the engine air intake will cause severe engine damage.
●Water entering the automatic transmission will cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ulti-
mately damage.
●Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the differentials, transmission and
transfer case, reducing the gear oil’s lubricating qualities.
■When you drive through water
If driving through water, such as when crossing shallow streams, first check
the depth of the water and the bottom of the river bed for firmness. Drive
slowly and avoid deep water.
■Inspection after off-road driving
●Sand and mud that has accumulated in brake drums and around brake
discs may affect braking efficiency and may damage brake system compo-
nents.
●Always perform a maintenance inspection after each day of off-road driv-
ing that has taken you through rough terrain, sand, mud, or water. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.

■Before driving the vehicle
Perform the following according to the driving conditions.
●Do not try to forcibly open a window or move a wiper that is
frozen. Pour warm water over the frozen area to melt the ice.
Wipe away the water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
●Check for and remove any excess ice or snow that may have
accumulated on the exterior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes
before getting in the vehicle.
■When driving the vehicle
Accelerate the vehicle slowly, keep a safe distance between you
and the vehicle ahead, and drive at a reduced speed suitable to
road conditions.
■When parking the vehicle
Park the vehicle and move the shift lever to “P” without setting
the parking brake. The parking brake may freeze up, preventing
it from being released. If necessary, block the wheels to prevent
inadvertent sliding or creeping.

Trailer towing
Your vehicle is designed primarily as a passenger-and-load-carrying
vehicle. Towing a trailer can have an adverse impact on handling,
performance, braking, durability, and fuel consumption. For your
safety and the safety of others, you must not overload your vehicle
or trailer. You must also ensure that you are using appropriate tow-
ing equipment, that the towing equipment has been installed cor-
rectly and used properly, and that you employ the requisite driving
habits.
Vehicle-trailer stability and braking performance are affected by
trailer stability, brake performance and setting, trailer brakes, the
hitch and hitch systems (if equipped).
To tow a trailer safely, use extreme care and drive the vehicle in
accordance with your trailer’s characteristics and operating condi-
tions.
Toyota warranties do not apply to damage or malfunction caused by
towing a trailer for commercial purposes.
Contact your Toyota dealer for further information about additional
requirements such as towing kits, etc.
