When trouble arises
■High coolant temperature warning light (warning buzzer)*
*: This light illuminates on the multi-information display.
■Front passenger detection sensor, seat belt reminder and warning buzzer
●If luggage is placed on a front passenger seat, the front passenger detection sensor may cause the warning light to flash and the warning buzzer to sound even if a passenger is not
sitting in the seat.
●If a cushion is placed on the seat, the sensor may not detect a passenger, and the warning
light may not operate properly.
■If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp w ill come on if the fuel tank becomes completely empty. If
the fuel tank is empty, refuel the vehicle immediately. The malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer as soon as possible.
■Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage temporarily drops, the electric power steering system warning lig ht may come on and the warning buzzer may sound.
■Tire pressure warning light
When a malfunction occurs in the tire pressure warning system, the tire pressure warning light blinks to warn the driver. However, if the warning light blinks for 1 minute, and then
remains illuminated, maki ng it difficult to determine whether the warning light is blinking, turn the engine switch fr om off to IGNITION ON mode and check if the warning light blinks.
■When the tire pressure warning light comes on
Carry out the following procedure after the tire temperature has lowered sufficiently.
●Check the tire inflation pressure and adjust to the appropriate level.
●If the warning light does not go out even after several minutes, check that the tire inflation
pressure is at the specified level and carry out initialization. ( P.335)
The warning light may come on again if the above operations are conducted without first
allowing the tire temperature to lower sufficiently.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on du e to natural causes such as natural air leaks
and tire inflation pressure changes caused by temperature. In this case, adjusting the tire inflation pressure will turn off the warning light (after a few minutes).

 P.330
■If the tire pressure warning light frequently comes on after blinking for 1 minute
If the tire pressure warning lig ht frequently comes on after blinking for 1 minute when the engine switch is turned to IGNITION ON mode , have it
checked by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.

WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized Lexus retailer
or Lexus authorized repairer, or any reliabl e repairer. The vehicle will become extremely unstable during braking, and the ABS system may fail, which could cause an accident resulting in death or serious injury.
■When the electric power steering system warning light comes on
When the light comes on yellow, the assist to the power steering is restricted. When the
light comes on red, the assist to the power st eering is lost and handling operations of the steering wheel become extremely heavy. When steering wheel operations are heavier than usual, grip the steering wheel firmly and operate it using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a loss of vehi-
cle control and result in death or serious injury.
●Decelerate to the lowest appropriate speed as soon as possible. Do not drive over 80 km/h (50 mph).
●Check and adjust the tire inflation pressure immediately.
●If the tire pressure warning light comes on ev en after tire inflation pressure adjustment, it is probable that you have a flat tire. Have the flat tire replaced by nearest authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could lose control of the steering wheel or the brakes.

the positive (+) terminal is removed, a spark may occur, leading to a fire in addi-tion to electrical shocks and death or
serious injury.
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flamma-
ble gas that may be emitted from the 12- volt battery:
●Make sure each jumper cable is con-nected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.

●Do not allow the other end of the jumper cable connected to the “+” ter-
minal to come into contact with any other parts or metal surfaces in the area, such as brackets or unpainted
metal.
●Do not allow the + and - clamps of the jumper cables to come into contact with each other.
●Do not smoke, use matches, cigarette
lighters or allow open flame near the 12-volt battery.
●If the 12-volt battery fluid level is exces-sively low ( P.327), do not use the
12-volt battery.
■12-volt battery precautions
