MAINTENANCE LOG
MAINTENANCE
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 lter 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.

MAINTENANCE
Drive Shaft Boots
Check the drive shaft boots and clamps for
cracks, deterioration and damage. Replace
any deteriorated or damaged parts and, if
necessary, repack the grease. A qualied
technician should perform these operations.
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 specied intervals.
When performing inspections, check for
damage, excessive wear and oiliness, and
replace if necessary.
Engine/Inverter Coolant
Drain the cooling system and rell with an
ethylene-glycol type coolant. Inspect hoses
and connections for corrosion and leaks.
Tighten connections and replace parts
when necessary. A qualied 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.

EXPLANATION OF MAINTENANCE ITEMS
Rear Differential Oil
Inspect or replace at specied intervals.
When performing inspections, check each
component for signs of leakage. If you
discover any leakage, have it repaired by a
qualied technician immediately.
Spark Plugs
Replace at specied intervals. Install new
plugs of the same type as originally
equipped. A qualied technician should
perform this operation.
Steering Gear
Inspect for signs of leakage. If you
discover any leakage, have it repaired
immediately by a qualied technician.
Steering Linkage and Boots
With the vehicle stopped, check for
excessive freeplay in the steering wheel.
Inspect the linkage for bending and
damage and the dust boots for
deterioration, cracks and damage. Replace
any damaged parts. A qualied technician
should perform these operations.
Tire Rotation
Tires should be rotated according to the
instructions in the Owner’s Manual. When
rotating tires, check for damage and
uneven wear. Replace if necessary.
Wiper Blades
The wiper blades should not show any
signs of cracking, splitting, wear,
contamination or deformation. The wiper
blades should clear the windshield without
streaking or skipping.
