■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.
■When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than us ual when operating, hold firmly and oper-
ate 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
vehicle 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 a tire is flat, change it
with 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.

If the hybrid system will not start
One of the following may be the cause of the problem:
●The electronic key may not be functioning properly.* (
P. 5 6 0 )
●There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle. ( P. 7 1 )
●There may be a malfunction in the immobilizer system.* ( P. 74 )
●There may be a malfunction in the shift control system.* ( P. 1 5 8 , 5 3 9 )
●The hybrid system may be malfunctioni ng due to an electrical problem such
as electronic key battery depletion or a blown fuse. However, depending on
the type of malfunction, an interim meas ure is available to start the hybrid sys-
tem. ( P. 5 5 9 )
*: It may not be possible to shift the shift position other than P.
One of the following may be the cause of the problem:
●The 12-volt battery may be discharged. ( P. 5 6 2 )
●The 12-volt battery terminal connections may be loose or corroded.
( P. 4 8 6 )
Reasons for the hybrid system not starting vary depending on the situation.
Check the following and perform the appropriate procedure:

■Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the hybrid system is off.
●Turn off any unnecessary electrical components when the vehicle is running at a low
speed for an extended period, such as in heavy traffic.
■When the 12-volt battery is removed or discharged
●The hybrid system may not start. ( P. 4 8 8 )
●If the 12-volt battery discharges while the shift position is in P, it may not be possible to
shift the shift position to othe r positions. In this case, the vehicle cannot be towed with-
out lifting both front wheels because the front wheels will be locked. (P. 5 2 4 )
●When the 12-volt battery is reconnected, start the hybrid system and confirm that the
shift position can be changed to each po sition using the shift position indicator.
■Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when the vehicle
is not in use, due to natural discharge and the draining effects of certain electrical appli-
ances. If the vehicle is left for a long time, the 12-volt battery may discharge, and the
hybrid system may be unable to start. (The 12-volt battery recharges automatically while
the hybrid system is operating.)
WA R N I N G
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to preven t accidentally igniting the flammable gas
that may be emitted from the 12-volt battery:
●Make sure each jumper cable is connected 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 “+” terminal 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 jump er cables to come into contact with each
other.
●Do not smoke, use matches, cigarette lighters or allow open flame near the 12-volt
battery.
