tem functions may be restricted to
protect the battery.
Also, battery per formance may
decrease and the engine may not
be able to restart. Contact your
Toyota dealer for details.
●Vehicles without Stop & Start sys-
tem: Use a battery that the case
size is same as the previous one
(LN3), 20 hour rate capacity
(20HR) is equivalent (70Ah) or
greater, and per formance rating
(CCA) is equivalent (603A) or
greater.

cially a tie, a scarf or a muffler)
away from the fan and belts.
Failure to do so m ay cause the
hands or clothing to be caught,
resulting in serious injury.
●Do not loosen the radiator cap
and the coolant reservoir cap
while the engin e and radiator
are hot.
High temperature steam or
coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the
engine has cooled down suffi-
ciently. Adding cool coolant to a
hot engine too quickly can cause
damage to the engine.
■To prevent damage to the
cooling system
Observe the following precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust, etc.).
●Do not use any coolant additive.
