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.

■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
your Lexus dealer.

CAUTION
■Off-road driving precautions
Always observe the following precautions to help minimize the risk of serious per-
sonal 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 wh en driving off-road. A bad bump could
jerk the wheel and injure your hands. Keep both hands and especially 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, rags, 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 te rrain, do not drive at excessive speeds,
jump, make sharp turns, strike objects, etc. This may cause loss of control or vehi-
cle rollover causing death or serious injury. You are also risking expensive dam-
age to your vehicle’s suspension and chassis.
NOTICE
■To prevent the water damage
Take all necessary safety measures to ensure that water dama ge 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 ultimately dam-
age.
●Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the differentials, transmission and transfer case, reduc-
ing the gear oil’s lubricating qualities.

■Before towing
Check that the following conditions are met:
●The vehicle’s tires are properly inflated. (P. 3 0 2 )
●Trailer tires are inflated according to the trailer manufacturer’s recommenda-
tion.
●All trailer lights work.
●All lights work each time you connect them.
●The trailer ball is set up at the proper height for the coupler on the trailer.
●The vehicle remains level when a loaded or unloaded trailer is hitched. Do not
drive if the vehicle is not level, and check for improper tongue load, overloading,
worn suspension, or other possible causes.
●The trailer cargo is securely loaded.
●The rear view mirrors conform to all applicable federal, state/provincial or local
regulations. If they do not, install rear view mirrors appropriate for towing pur-
poses.
■Break-in schedule
Lexus recommends that you do not use a new vehicle or a vehicle with any new
power train components (engine, transmission, differential, wheel bearings, etc.) to
tow a trailer for the first 500 miles (800 km) of driving.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Warranty and Services Guide/ Owner’s Manual Sup-
plement/ Scheduled Maintenance”.)
●Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.
