160 2-3. Operating the lights and wipers
■Daytime running light system (if equipped)
To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the engine is started and the
parking brake is released. Daytime running lights are not designed for use at
night.
■ Headlight control sensor
■ Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30
seconds after all doors are closed with the engine switch turned to the
ACC or LOCK position. (The lights turn off immediately if the LOCK but-
ton on the wireless remote control is pressed twice after all doors are
locked.)
● When only the tail lights come on: The tail lights turn off automatically
with the engine switch turned to the ACC or LOCK position and the
driver’s door is opened.
If the driver’s door is kept open, the lights automatically turn off after 30 min-
utes.
To turn the lights on again, turn the engine switch to the ON position, or turn
the headlight switch off once and then back to the or position.
■ Customization that can be co nfigured at Toyota dealer
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features P. 495)
The sensor may not function properly if
an object is placed on the sensor, or any-
thing 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.

Selecting vehicle heightHigher
Lower
Vehicle height can be adjusted
only when the engine is running.
The height control indicator
stops blinking, and comes on
continuously to indicate that the
mode shift is completed.
■ Height modes
●N mode (normal mode): For ordinary driving
Normal height
● HI mode (high mode): For driving on bumpy roads and through
water
1.6 in. (40 mm) higher than the normal height
The HI mode is unavailable w hen the vehicle’s speed exceeds
18 mph (30 km/h).
When the vehicle’s speed exceed s 18 mph (30 km/h), the height
will be adjusted to the norm al height automatically.

172 2-4. Using other driving systems
■Automatic leveling function
Regardless of the number of occupants or the luggage load, vehicle height
in any mode is always adjusted to a fixed height by the automatic leveling
function.
■ When HI mode is selected
The vehicle height will change to N mode when driving at the speeds of 1\
8
mph (30 km/h).
■ When LO mode is selected
●The vehicle height will change to N mode when vehicle speed exceeds 7
mph (12 km/h).
● This mode allows for easy access to the vehicle (getting in and out) and
easy loading and unloading.
■ The electronically modulated air susp ension will not operate in the fol-
lowing cases:
● The underbody of the vehicle is touching the surface of the road.
● The area around the suspension is covered with ice.
The height control indicators will blink, turn off and then turn on continuously
to indicate that the electronically modulated air suspension is not opera-
tional.
To re-enable operation, turn off the engine and then restart it.
■ Even if you hear an operating noise
This does not indicate a problem in the electronically modulated air suspen-
sion.
■ If there is a problem somewhere in the electronically modulated air
suspension
The height control OFF indi cator will behave as follows:
● The indicator will not come on when the engine switch is turned on.
● The indicator will blink.
Although the vehicle may be driven, have the vehicle inspected by your Toy-
ota dealer.

When driving
CAUTION
■The electronically modulated air susp ension must be turned off in the
following circumstances:
Otherwise, the automatic leveling function may cause the vehicle’s height to
change, resulting in an unexpected accident.
● When driving through water such as shallow streams (Put the vehicle
height in HI mode and turn off the electronically modulated air suspension.
Drive at 18 mph [30 km/h] or slower.)
● When jacking up the vehicle, installing tire chains or tying the vehicle with
chains/wires for transportation via flat bed truck (Turn the system off and
stop the engine.)
● When the vehicle must be towed (Put the vehicle height in N mode and
turn the system off.)
● When the vehicle gets stuck (Turn the system off.)
● When disconnecting a trailer (Put the vehicle height in LO mode and turn
the system off.)
■ Selecting the correct height mode
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the vehicle, as well as dan-
gerous handling characteristics, which may lead to fatal or injury accidents.
●Before you lower the vehicle’s height, check under the vehicle to make
sure that no one is there.
● The HI mode should be used for off-road driving conditions.
As the vehicle’s center of gravity is higher in this setting, the vehicle may
become unstable when turning abruptly.
● Do not select HI mode when you load cargo on the roof luggage carrier.
This may result in a loss of control or vehicle rollover.

When driving
AUTO LSD system (2WD models and Multi-mode 4WD models)
The AUTO LSD system aids traction by using the traction control
system to control engine performance and braking when one of the
rear wheels begins to spin.
The system should be used only wh en one of the rear wheels spin-
ning occurs in a ditch or rough surface.
■ System operation
The system can be used on 2W D models and in 2WD mode on
4WD models.
The system is activated when dr iving at a speed under 62 mph
(100 km/h).
Press the VSC OFF switch to
turn on the system.
At this time, the AUTO LSD
and slip indicators will come
on.
To turn off the system, push
the switch again.
If the engine is turned off while
the AUTO LSD and slip indica-
tors are on and then restarted,
the indicator will turn off auto-
matically.

When driving
When the active traction control system is operating
If all wheels spin, the slip indica-
tor flashes to indicate that the
active traction control system
have been engaged.
■When the rear differential is locked (vehicles with the rear differential
lock system)
The active traction control system is activated only when the vehicle speed
is less than 4 mph (6 km/h).
■ Sounds and vibrations caused by the active traction control system
●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 the system.
● Vibrations may be felt through the vehicle body and steering. It may
occur when the system is operating.
■ If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
Stop the vehicle in a safe place. (Ther e is no problem with continuing normal
driving.)
CAUTION
■ The active traction control system m ay not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the active traction control system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
