■The windshield wipers and w asher can be operated when
The engine switch is in the “ON” position.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washe r fluid in the
windshield washer fluid reservoir.
WARNING

warm. The fluid may freeze on the windshield and cause low visi bility. This
may lead to an accident, resulting in death or serious injury.
NOTICE

Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When a nozzle becomes blocked
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

• If a vehicle ahead makes an abrupt maneuver (such as sudden swerving,
acceleration or deceleration)
• When suddenly cutting behind a preceding vehicle
• When driving in inclement weather such as heavy rain, fog, snow or a sandstorm
• When the vehicle is hit by water, snow, dust, etc., from a veh icle ahead
• When driving through steam or smoke
• When driving in a place where the surrounding brightness changes sud-
denly, such as at the entrance or exit of a tunnel
• When a very bright light, such as the sun or the headlights of oncoming traffic, shines directly into the camera sensor
• When the surrounding area is dim, such as at dawn or dusk, or while at
night or in a tunnel
• After the engine has started the vehicle has not been driven for a certain

Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenl y,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake p edal
is depressed when the system de tects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake
pressure for individual wheels and reducing driving torque when
trailer sway is detected
◆TRAC (Traction Control) for 2WD models and 2WD mode on
4WD models
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicl e or accelerating on slippery roads
◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when start -
ing on an uphill
To keep driving safety and perf ormance, the following systems
operate automatically in respon se to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heav ily when operating the vehi-
cle.

3104-5. Using the driving support systems
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
Wheel lock-up occurs when the trailer wheel squeals or tire smo ke occurs.
Trailer wheels may not lock-up while driving heavily loaded trailer. During this
case, adjust the Trailer gain to the highest allowable setting for the towing
condition.
■ When disconnecting and reco nnecting battery terminals
The gain setting data will be reset.

WARNING
■Trailer brake type setting
It is the responsibility of the driver to make sure the trailer brakes are func-
tioning normally and adjusted appropriately. Failure to check a nd maintain
trailer brakes may result in loss of vehicle control, crash, or serious injury.
Trailer brake control system will work with most electric and e lectric-over-
hydraulic trailer braking systems up to 3 axles (24A output to trailer brakes).
Please be sure to test compatibility with the system at low spe eds and in a
safe area. If a warning message appears in the multi-information display
( P. 563), have the vehicle inspected by your Toyota dealer immed iately.
Some electric-over-hydraulic trailer brakes will take some mini mum output
to activate. Trailer brake control system will not work with tr ailer hydraulic
surge brakes.
■ When driving on slippery road surfaces
When stopping with ABS activated, output to the trailer might b e reduced in
order to reduce the likelihood of trailer wheels to lock. The trailer is not
equipped with ABS. Drive safely on slippery road surfaces.

Driving
●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 the vehicle is parked without setting the pa rking
brake, make sure t o block the wheels.
Failure to do so may be dangerou s because it may cause the vehi-
cle to move unexpectedly, pos sibly leading to an accident.
● If the vehicle is parked without setting the parking brake, confirm
that the shift lever c annot be moved out of P
*.
*: The shift lever will be locked if it is attempted to be shift ed from P to any
other position without depressing the brake pedal. If the shift lever can be
shifted from P, there may be a problem with the shift lock syst em. Have the
vehicle inspected by your Toyota dealer immediately.
Observe the following precautions when switching fuels, in orde r to
maintain starting a nd driving performance.
● Do not change fuels when the fuel level is 1/4 or less.
● Always add at least 2.6 gal. (10 L) of fuel.
● After filling up with fuel, warm up the engine or drive the vehicle for
at least 5 minutes or 7 miles (11 km).
● Do not accelerate rapidly im mediately after refueling.
Use the correct tire chain size when mount ing the tire chains.
Chain size is regulate d for each tire size.
Side chain
(0.2 in. [5 mm] in diameter)
Cross chain
(0.25 in. [6.3 mm] in diameter)
