1 Inspect sealed transmissions, transfer cases and differentials for signs of leakage. If any leakage from a sealed component is suspected, it is recommended that you have the sealed component inspected by a Toyota dealer. Inspect power steering fluid (if equipped) and brake fluid level/condition. Inspect engine and inverter (if equipped) coolant level/condition/freezing point. Your dealer may recommend services (Dealer-Recommended Maintenance) based on inspection results.2 Reset the oil replacement reminder light (“MAINT REQD”) or the message “OIL MAINTENANCE REQUIRED” on the multi-information display after maintenance at every 5,000 miles.3 Perform these service items only if you drive primarily under the conditions indicated.4 Refer to “Engine/Inverter Coolant” in the “Explanation of Maintenance Items” section in the back of this guide for more information.5 Visually check the HV battery cooling intake filter for dirt or dust every 5,000 miles and clean if necessary. Clean every 20,000 miles.6 Not all vehicles are designed for towing. Refer to your Vehicle Owner’s Manual for details.
NOTE: Driving in heavy traffic, on dirt roads or in urban, dusty or desert areas may shorten the life of the cabin air filter. Replacement may be needed if you notice reduced airflow from the air conditioner and heater or if the windows fog easily when you use the Fresh mode. Consult your dealer if any of these conditions occur.

MAINTENANCE
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.
