Activating the downhill assist control system
Press the “DAC” switch.
The downhill assist control sys-
tem indicator will come on to
indicate that the downhill assist
control system is activated.
Pressing the switch again turns
the system off.
The slip indicator will flash to indi-
cate that the downhill assist con-
trol system is operating, and the
stop lights and high mounted
stoplight will turn on.
■
Conditions in which the downhill assist control system does not operate
● In the following situations, the downhill assist control system indicator
flashes and the downhill assist control system does not operate or will stop
operating:
• The shift lever is not in 1 range of S mode or R.
• The vehicle speed is higher than 15 mph (25 km/h).
● If the accelerator or brake pedal is depressed, the downhill assist control
system will stop operating with the downhill assist control system indicator
still on.
Downhill assist control system (AWD mod-
els)
With the downhill assist control system, the vehicle is able to
descend a steep hill, maintaining a constant low speed of about
3 mph (5 km/h) without brake pedal operation.

If the “DAC” switch is turned off during operation of the downhill assist
control system
The downhill assist control system gradually ceases operation. The downhill
assist control system indicator will flash during the canceling operation, and
then go off when the system is fully off.
■ Downhill assist control system operation sound
●A sound may be heard from the engine compartment during operation of the
downhill assist control system. This sound does not indicate a malfunction.
● If the accelerator or brake pedal is depressed during operation of the down-
hill assist control system, a sound caused by the release of system opera-
tion may be heard, or you may feel the brake pedal push-back. This does
not indicate a malfunction.
■ When the downhill assist control system operates continuously
The brake actuator may overheat. In that case, the downhill assist control
system will stop operating, a buzzer will sound and the downhill assist control
system indicator will start flashing. Re frain from using the system until the
downhill assist control system indicator stays on. (There is no problem with
continuing to drive normally.)
■ If the slip indicator comes on
It may indicate a malfunction in the system. Contact your Toyota dealer.
WARNING
■Conditions which may affect the downhill assist control system opera-
tion
●Do not rely too heavily on the downhill assist control system. On extremely
steep inclines, icy surfaces or muddy roads, the vehicle may slip and the
system may not be able to maintain the constant low vehicle speed of
about 3 mph (5 km/h), leading to an accident causing death or serious
injury.
● Do not shift the shift lever to R while driving forward, or to D while driving
backward. Doing so may cause the wheels to lock up, leading to an acci-
dent causing death or serious injury. In addition, excessive stress will be
applied to the automatic transmission, possibly resulting in damage.

◆Pre-collision warning
When a high possibility of a
frontal collision is detected, the
pre-collision system warning
light flashes, a buzzer sounds
and a message is shown on the
multi-information display to
urge the driver to take evasive
action.
◆Pre-collision brake assist
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.
The system may not warn the driver using a warning light, warning
display and buzzer when the system detects and judges braking
operations.
◆Pre-collision braking
When there is a high possibility of a frontal collision, the system
warns the driver using a warning light, warning display and buzzer.
If the system determines that a collision is unavoidable, the brakes
are automatically applied to reduce the collision speed.
PCS (Pre-Collision System)
: If equipped
When the radar sensor detects that a frontal collision is highly
likely or even unavoidable, safety systems such as the brakes
and seat belts are automatically engaged to lessen impact as
well as vehicle damage.The pre-collision system can be turned on and off as necessary by
operating the switch. ( P. 307)

● Pre-collision braking:
• The VSC OFF switch is not pressed.
• Vehicle speed is greater than about 10 mph (15 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehi-
cle running ahead of you is greater than about 10 mph (15 km/h).
■ Conditions that may trigger the system even if there is no danger of a
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
● 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 there is a metal plate in the road in front of the vehicle on a downhill
slope
● When climbing a steep hill causes an overhead billboard or other metallic
structure to appear directly in the vehicle’s line of travel
● When driving under an overpass
● When an extreme change in vehicle height occurs
● When passing through certain toll gates
● When passing through a tunnel
● When the radar sensor moves off position due to its surrounding area being
subjected to a strong impact
When the system is activated in the situations described above, there is also
a possibility that the brakes will be applied with a force greater than normal.

WARNING
■Limitations of the pre-collision system
Do not overly rely on the pre-collision system. Always drive safely, taking
care to observe your surroundings and checking for any obstacles or other
road hazards.
Failure to do so may cause an accident resulting in death or serious injury.
■ When the sensor may not be corr ectly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations:
● When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
● When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
● Vehicles that cut in suddenly
● Vehicles with small rear ends (trailers with no load on board etc.)
● Motorcycles traveling in the same lane
■ Handling the radar sensor
Observe the following to ensure the pre-collision system can function effec-
tively.
Otherwise, the system may not function correctly and could result in an
accident.
●Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or
damage them.
● Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction.
If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by your Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
● Do not modify or paint the sensor and grille cover.
● Do not replace them with non-genuine parts.

WARNING
■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-collision system is intended
to assist the driver in avoiding collisions through the process of LOOK-
JUDGE-ACT. There are limits to the degree of assistance the system can
provide, so please keep in mind the following important points.
●Assisting the driver in watching the road
The pre-collision system is only able to detect obstacles directly in front of
the vehicle, and only within a limited range. It is not a mechanism that
allows careless or inattentive driving, and it is not a system that can assist
the driver in low-visibility conditions. It is still necessary for the driver to
pay close attention to the vehicle’s surroundings.
● Assisting the driver in making correct judgment
When attempting to estimate the possibility of a collision, the only data
available to the pre-collision system is that from obstacles it has detected
directly in front of the vehicle. Theref ore, it is absolutely necessary for the
driver to remain vigilant and to deter mine whether or not there is a possi-
bility of collision in any given situation.
● Assisting the driver in taking action
The pre-collision system’s braking assist feature is designed to help
reduce the severity of a collision, and so only acts when the system has
judged that a collision is unavoidable. This system by itself is not capable
of automatically avoiding a collision or bringing the vehicle to a stop safely.
For this reason, when encountering a dangerous situation the driver must
take direct and immediate action in order to ensure the safety of all
involved.

3244-6. Driving tips
HIGHLANDER_U (OM48A12U)
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 accu-
mulated 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.
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
Park the vehicle and move the shift lever to P without setting the park-
ing brake. The parking brake may freeze up, preventing it from being
released. If necessary, block the wheels to prevent inadvertent sliding
or creeping.

WARNING
■Off-road driving precautions
Always observe the following precautions to minimize the risk of death, seri-
ous injury or damage to your vehicle:
●Drive carefully when off the road. Do not take unnecessary risks by driving
in dangerous places.
● Do not grip the steering wheel spokes when driving off-road. A bad bump
could jerk the wheel and injure your hands. Keep both hands and espe-
cially your thumbs on the outside of the rim.
● Always check your brakes for effectiveness immediately after driving in
sand, mud, water or snow.
● After driving through tall grass, mud, rock, sand, rivers, etc., check that
there is no grass, bush, paper, r ags, stone, sand, etc. adhering or trapped
on the underbody. Clear off any such matter from the underbody. If the
vehicle is used with these materials trapped or adhering to the underbody,
a breakdown or fire could occur.
● When driving off-road or in rugged terrain, do not drive at excessive
speeds, jump, make sharp turns, strike objects, etc. This may cause loss
of control or vehicle rollover causing death or serious injury. You are also
risking expensive damage to your vehicle’s suspension and chassis.
