Driving
■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving,
the daytime running lights turn on automatically whenever the engine is
started and the parking brake is released with the headlight switch off or in
the “AUTO” position. (Illuminate brighter than the parking lights.) Daytime
running lights are not designed for use at night.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor (vehicl es with automatic headlight system)
■ Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30 sec-
onds after a door is opened and closed if the engine switch is turned to the
“ACC” or “LOCK” position. (The lights turn off immediately if the button
on the key is pressed after all the doors are locked.)
● When only the tail lights come on: The tail lights turn off automatically if the
engine switch is tuned to the “ACC” or “LOCK” position and the driver’s door
is opened.
Vehicles with automatic headlight system: If any of the doors is kept open, the
lights automatically turn off after 20 minutes.
To turn the lights on again, turn the engine switch to the “ON” position, or turn
the light switch off once and then back to or .
■ Light reminder buzzer
A buzzer sounds when the key is removed from the engine switch and the
driver’s door is opened while the lights are turned on.
■ Customization that can be co nfigured at Toyota dealer
Settings (automatic light off system) can be changed.
(Customizable features: →P. 543)
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
NOTICE
■
To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not
running.

1994-3. Operating the lights and wipers

Driving
■The windshield wipers and washer 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 washer fluid in the
windshield washer fluid reservoir.
CAUTION
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■When the windshield is dry
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.

2354-5. Using the driving support systems

Driving
Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
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 pedal
is depressed when the system detects 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 engine torque when
trailer sway is detected.
Trailer Sway Control is part of the VSC system and will not operate if
VSC system is turned off or experiences a malfunction.
◆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 vehicle or accelerating on slippery roads
◆A-TRAC (Active Traction Control) for 4WD mode on 4WD mod-
els
Maintains drive power and prevents all wheels from spinning when
starting the vehicle or accelerating on slippery roads.
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

2444-5. Using the driving support systems
While driving 20 - 25 mph [35 - 40 km/h], fully apply the manual
TRAILER BRAKE OUTPUT
slider.
Adjust the gain settin g, using the GAIN (+/-) selection buttons, to
either increase or decrease to just 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 trailer. 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 smoke 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.
CAUTION
■ 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 and maintain
trailer brakes may result in loss of vehicle control, crash, or serious injury.
Trailer brake control system will work with most electric and electric-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 speeds and in a
safe area. When a warning message appears in the multi-information dis-
play ( →P. 485), the gain setting may be too high. Please use the trailer
brakes with reduced gain. If there is still a problem, have the vehicle
inspected by your Toyota dealer immediately.
Some electric-over-hydraulic trailer brakes will take some minimum output
to activate. Trailer brake control system will not work with trailer hydraulic
surge brakes.
■ When driving on slippery road surfaces
When stopping with ABS activated, output to the trailer might be reduced in
order to reduce the likelihood of trailer to sway or trailer wheels to lock. The
trailer is not equipped with ABS. Drive safely on slippery road surfaces.

2464-6. Driving tips
●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 parking
brake, make sure to block the wheels.
Failure to do so may be dangerous because it may cause the vehi-
cle to move unexpectedly, pos sibly leading to an accident.
● If the vehicle is parked without se tting the parking brake, confirm
that the shift lever ca nnot be moved out of P
*.
*: The shift lever will be locked if it is attempted to be shifted 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 system. Have the
vehicle inspected by your Toyota dealer immediately.
Observe the following precautions when switching fuels, in order to
maintain starting and 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 immediately after refueling.
Use the correct tire chain size when mounting the tire chains.
Chain size is regulated for each tire size.
Side chain
(0.2 in. [5 mm] in diameter)
Cross chain
(0.25 in. [6.3 mm] in diameter)

2524-6. Driving tips
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”.
