Avoid sudden starts or erratic driving maneuvers which place excessive stress
on the emergency towing eyelets and the cables or chains. Always be cautious
of the surroundings and other vehicles while towing.
If the hybrid system is off, the power assist for the brakes and steering will not
function, making steering and braking more difficult.

when the power switch is turned to ON mode, have it checked by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.

audio sound.
CAUTION
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
dealer or repairer, or another duly qualified and equipped professional. 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.

pressure immediately.
If the tire pressure warning light comes on even after tire inflation pressure
adjustment, it is probable that you have a flat tire. Check the tires. If a tire is
flat, repair the flat tire by using emergency tire puncture repair kit.
Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
Vehicles with run-flat tires
Decelerate to the lowest appropriate speed as soon as possible. Do not drive
over 60 km/h (37 mph).
Check and adjust the tire inflation pressure immediately.
If the tire pressure warning light comes on even after tire inflation pressure
adjustment, it is probable that you have a flat tire. Have the tire replaced by
the nearest authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
