Driver’s Floor Mat
• Only use the driver’s floor mat
designed specifically for the model
and model year of your vehicle.
• Always properly secure the driver’s
floor mat using the retaining hooks.
• Never install another floor mat on top
of the existing driver’s floor mat.
• Never install the driver’s floor mat
upside down.
Engine Air Filter
Inspect or replace at specified intervals.
When performing inspections, check for
damage, excessive wear and oiliness, and
replace if necessary.
Engine/Inverter Coolant
Drain the cooling system and refill with an
ethylene-glycol type coolant. Inspect hoses
and connections for corrosion and leaks.
Tighten connections and replace parts
when necessary. A qualified technician
should perform these operations. (For
further details, refer to “Radiator, Condenser
and Hoses” in the “Maintenance and Care”
section of the Owner’s Manual).
Your Toyota is equipped with Genuine
Toyota Super Long-Life Coolant. The
replacement intervals for engine coolant
recommended in this booklet are based
on replacement with Genuine Toyota
Super Long-Life Coolant or similar
high-quality non-silicate, non-amine,
non-borate ethylene-glycol coolant with
long-life hybrid organic acid technology
(i.e., a combination of low phosphates
and organic acids). If another type of
ethylene-glycol coolant is used,
replacement intervals may be different.
