CAUTION
■If a safety system warning light does not come on
Should a safety system light such as ABS and the SRS airbag warning lights not
come on when the ignition key is turned to the “ON” position, this could mean that
these systems are not available to help protect you in an accident, which could
result in death or serious injury. Have the vehicle inspected by your Lexus dealer
immediately if this occurs.
■ Warning lights
Warning lights inform the driver of malfunctions in the indicated
vehicle’s systems. ( P. 3 3 7 )
*: These lights turn on when the ignition key is turned to the “ON” position
to indicate that a system check is being performed. They will turn off
after the engine is started, or after a few seconds. There may be a mal-
function in a system if the lights do not come on, or if the lights do not
turn off. Have the vehicle inspected by your Lexus dealer.

■Daytime running light system
To make your vehicle more visible to other drivers, the headlights turn on automati-
cally (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
The headlights and tail lights turn off 30 seconds after a door is opened or closed if

turned on. (The lights turn off immediately if the LOCK button on the key is pressed
after all doors are locked.)
To turn the lights on again, turn the ignition key to the “ON” position, or turn the light
switch “OFF” once and then back to the or position.
■Customization
Settings (e.g. light sensor sensitivity) can be changed. ( P. 3 8 9 )

■To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not running.
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

When driving
■Extra high mode
If the vehicle becomes stuck, extra high mode may be automatically selected when
the vehicle height is in high mode with the four-wheel drive control lever in the “L”
position.
The vehicle height is raised to 2.8 in. (70 mm) higher than the normal mode height,
or slightly higher.
Extra high mode will change back to high mode when:
• The vehicle is no longer stuck
• The four-wheel drive control lever is shifted to a position other than “L”
●If you push “ ▼” when in extra high mode, normal mode is selected.
●Extra high mode cannot be manually selected.
■Turning off the active height control suspension
●The system will remain off until the switch is pushed again, even if the ignition is
turned off.
●Even if AHC is turned off, the system automatically selects the normal mode if
the vehicle's speed exceeds 19 mph (30 km/h).
■Automatic leveling function
The vehicle is adjusted to a fixed height for each mode, regardless of the number of
occupants and the luggage load.
●However the vehicle cannot be raised if the vehicle load exceeds the following
limits:
• Up to 4 occupants* plus approximately 661 lb. (300 kg) in the normal mode
• Up to 4 occupants* plus approximatel y 375 lb. (170 kg) in the high mode
*: average weight 150 lb. (68 kg) per person
●If the vehicle height cannot be raised when in the normal mode, and “LO” is lit
on the height mode indicator, the vehicle is loaded too heavily. Take extra care
when driving in this condition.
If the vehicle height cannot be raised even after unloading the vehicle, press
“ ▼ ” then “ ▲” on the height mode select switch. If the vehicle height still cannot
be raised, turn the ignition off th en on again, then try once more.

■Parking and stopping tips
●If you immediately stop the engine after off-road driving, or park the vehicle for
a long time, the vehicle height may gradually lower. When parking, make sure
there is nothing under the vehicle that may come in contact with the underbody.
The vehicle will return to the set height when the engine is started.
●The vehicle height may change as the temperature changes when the engine is
stopped. The vehicle will return to the set height when the engine is started.
■Propeller shaft noise
If the vehicle height is adjusted on a slop e, or with the selector lever in a position
other than “P” or “N” while the vehicle is stopped, you may hear a sound caused by
the expansion and contraction of the propel ler shaft. This does not indicate a mal-
function.
■Continued system operation
Even if the engine is stopped while the ve hicle height is being lowered, operation
will continue for up to 12 seconds.
■Active height control failure warning
●If a malfunction occurs in the AHC system, normal mode is automatically
selected.
The height control “ OFF” indicator will bl ink, and AHC cannot be activated until
the malfunction is corrected.
Stop the engine and start it again. If the height control “OFF” indicator light
turns off, the system is operating correc tly. If the indicator light continues to
blink, have the vehicle checked at your Lexus dealer as soon as possible.
●If the height control “OFF” indicator light does not come on when the ignition
switch is turned on, there is a malfunction in the AHC system. You can continue
normal driving, however have the vehicle checked by your Lexus dealer as soon
as possible.
■Installing or removing heavy equipment
If the equipment exceeds 33 lb. (15 kg), the front torsion bar must be adjusted. See
