CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving mane uvers which place excessive stress on the
emergency towing hook and the elastic towing rope. Always be cautious of the sur-
roundings and other vehicles while towing.
●Do not turn the engine switch off.
Doing so will lock the steering wheel and pr event operation, possibly causing an acci-
dent and resulting in death or serious injury.
●If the engine is not running, the power assist for the brakes and steering will not func-
tion, making steering and braking more difficult.

NOTICE
■To prevent causing serious damage to the transmission and transfer when towing
using a wheel-lift type truck
Never tow this vehicle with any of th e wheels in contact with the ground.
■To avoid serious damage to your vehicle
■To prevent damage to the vehicle when towing using a wheel-lift type truck
When raising the vehicle, ensure adequate ground clearance for towing at the oppo-
site end of the raised vehicle. Without adequate clearance, the vehicle could be dam-
aged while being towed.
■To prevent damage to the vehicle during emergency towing
Observe the following precautions.
●Do not use cables or chains.
●Do not tow the vehicle at a speed higher than 19 mph (30 km/h) and more than a dis-
tance of 50 miles (80 km).
●Do not tow the vehicle from the rear.
●Do not secure elastic towing ropes to the suspension components.
If the vehicle is towed at a speed higher than 19 mph (30 km/h) or for more than
50 miles (80 km), or if the vehicle is towed from the rear, the transmission may be
damaged. In such cases, transport the vehicle using a flat bed truck with all four wheels
raised off the ground.
■To prevent body damage when to wing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
■To prevent causing serious damage to the transmission and transfer in emergency
towing
Never tow a vehicle from the rear with four wheels on the ground. This may cause seri-
ous damage to the transmission and transfer.
Do not use the rear emergency towing hook.

The driver’s seat belt buzzer sounds to alert the driver that his or her seat belt is not
fastened. Once the engine switch is turned to IGNITION ON mode, the buzzer
sounds for 6 seconds. If the vehicle reaches a speed of 12 mph (20 km/h), the buzzer
sounds once. If the seat belt is still unfastened after 30 seconds, the buzzer will sound
intermittently for 10 seconds. Then, if the seat belt is still unfastened, the buzzer will
sound in a different tone for 20 more seconds.
The front passenger’s seat belt buzzer sounds to alert the front passenger that his or
her seat belt is not fastened. The buzzer sounds once if the vehicle reaches a speed of
12 mph (20 km/h). If the seat belt is still unfastened after 30 seconds, the buzzer will
sound intermittently for 10 seconds. Then, if the seat belt is still unfastened, the buzzer

●If luggage is placed on the front passenger seat, the front passenger detection sensor
may cause the warning light to flash and the warning buzzer to sound even if a passen-
ger is not sittin g in the seat.
●If a cushion is placed on th e seat, the sensor may not detect a passenger, and the warn-
ing light may not operate properly.
■If the malfunction indicator lamp comes on while driving

GX460_OM_OM60K80U_(U)
CAUTION
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Lexus dealer. The vehi-
cle will become extremely unstable during braking, and the ABS system may fail, which
could cause an accident resulting in death or serious injury.
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause loss of vehi-
cle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure
immediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat tire. Check the tires. If the tire is flat, change to
the spare tire and have the flat tire repaired by the nearest Lexus dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could lose
control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.

When trouble arises
CAUTION
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recomm ended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure la bel (tire and load information label). (If your
vehicle has tires of a different size than the size indicated on the vehicle placard or tire
inflation pressure label [tire and load in formation label], you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure moni-
toring system (TPMS-tire pressure warning system) that illuminates a low tire pressure
telltale (tire pressure warning light) when on e or more of your tires is significantly
under-inflated. Accordingly, when the low ti re pressure telltale (tire pressure warning
light) illuminates, you should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency
and tire tread life, and ma y affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure wa rning system) is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure,
even if under-inflation has no t reached the level to trigger illumination of the TPMS low
tire pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system) mal-
function indicator to indicate when the system is not operating properly. The TPMS
(tire pressure warning system) malfunction indi cator is combined with the low tire pres-
sure telltale (tire pressure warning light). When the system detects a malfunction, the
telltale will flash for approximately one minu te and then remain continuously illumi-
nated. This sequence will cont inue upon subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) malfun ctions may occur for a variety of reasons,
including the installation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS (tire pressure warning system) from functioning properly. Always
check the TPMS (tire pressure warning syst em) malfunction telltale after replacing one
or more tires or wheels on your vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS (tire pressure warning system) to continue to function
properly.
NOTICE
■Precaution when inst alling a different tire
When differently constructed tires or tires of different makers, models or tread pat-
terns are installed, the tire pressure warning system may not operate properly.
