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 Visually check the FC HV battery cooling intake filter for dirt or dust every 5,000 miles and clean if necessary. Clean every
20,000 miles.
3 P erform these service items only if you drive primarily under the conditions indicated.4 N ot all vehicles are designed for towing. Refer to your Vehicle Owner’s Manual for details.
