If you perform maintenance by yourself, be sure to follow the correct
procedures as given in these sections.
ItemsParts and tools
Battery condition (except hybrid
vehicle) (P. 482)•Warm water
• Baking soda
• Grease
• Conventional wrench
(for terminal clamp bolts)

CAUTION
When working near the electric cooling fan or radiator grille
Except hybrid vehicle
Vehicles without a smart entry & start system:
Be sure the engine switch is in the “LOCK” position.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. (P. 481)
Vehicles with a smart entry & start system:
Be sure the “ENGINE START STOP” switch is off.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fan may automatically start to run if the air conditioning is on and/or
the coolant temperature is high. (P. 481)
Hybrid vehicle
Vehicles without an electronic key:
Be sure the engine switch is in the “LOCK” position.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. (P. 481)
Vehicles with an electronic key:
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fan may automat-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. (P. 481)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
