CAUTION
Burns
Use caution when seating the following persons in a seat with the seat
heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the disabled
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)
Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
NOTICE
To prevent seat heaters and ventilators damage
Do not put unevenly weighted objects on the seat and do not stick sharp
objects (needles, nails, etc.) into the seat.
To prevent battery discharge
Turn the switches off when the engine is off.

Overheating
If you observe the following, your vehicle may be overheating.
The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
Steam is coming from under the hood.
CAUTION
To prevent an accident or injury when inspecting under the hood of your
vehicle
If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injury such as burns.
Keep hands and clothing away from the fans and other belts while the
engine is running.
Do not loosen the radiator cap (IS250), or the coolant reservoir cap
(IS220d and IS200d) while the engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
Add engine coolant if neces-
sary.
Water can be used in an
emergency if engine coolant
is unavailable.
(P. 5 4 4)
Have the vehicle checked at the nearest authorized Lexus dealer
or repairer, or another duly qualified and equipped professional,
as soon as possible.
