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.

EXPLANATION OF MAINTENANCE ITEMS
T
he following descriptions are  
provided to give you a better 
understanding of the maintenance  
items that should be performed on your 
vehicle. The scheduled maintenance log 
indicates at which mileage/time intervals  
each item should be performed. Please  
note that many maintenance items should  
be performed only by a qualified technician.
For further information on maintenance 
items you can perform yourself, see the 
“Maintenance and Care” section of the 
Owner’s Manual.
Automatic Transmission Fluid 
Inspect or replace at specified intervals. 
When performing inspections, check each 
component for signs of leakage. If you 
discover any leakage, have it repaired by  
a qualified technician immediately.
Ball Joints and Dust Covers 
Check the suspension and steering  
linkage ball joints for looseness and  
damage. Check all dust covers for 
deterioration and damage. Replace  
any deteriorated or damaged parts.  
A qualified technician should perform  
these operations.
Brake Lines and Hoses
Visually inspect for proper installation.  
Check for chafing, cracks, deterioration  
and signs of leakage. Replace any 
deteriorated or damaged parts. A qualified 
technician should perform these operations.
Brake Linings/Drums and  
Brake Pads/Discs
Check the brake linings (shoes) and  
drums for scoring, burning, fluid leakage, 
broken parts and excessive wear. Check  
the pads for excessive wear and the discs  
for runout, excessive wear and fluid  
leakage. Replace any deteriorated or  
damaged parts. A qualified technician  
should perform these operations.
Cabin Air Filter
Replace at specified intervals. Driving in  
heavy traffic, on dirt roads or in urban,  
desert or dusty areas may shorten filter’s  
life. More frequent replacement may  
be necessary.
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 qualified 
technician should perform these operations.

EXPLANATION OF MAINTENANCE ITEMS
Rear Differential Oil
Inspect or replace at specified intervals.  
When performing inspections, check each 
component for signs of leakage. If you 
discover any leakage, have it repaired by a 
qualified technician should immediately. 
Spark Plugs
Replace at specified intervals. Install new 
plugs of the same type as originally  
equipped. A qualified technician should 
perform this operation.
Steering Gear
Inspect for signs of leakage. If you  
discover any leakage, have it repaired 
immediately by a qualified 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 qualified technician 
should perform these operations.
Tire Rotation
