NOTICE
Adding cool coolant to a hot hybrid system too quickly can cause damage to the
hybrid system.
■
To prevent damage to the cooling system
Observe the following precautions:
●
Avoid contaminating the coolant with foreign matter (such as sand, dust, etc.).
●
Do not use coolant additives.
6 Start the hybrid system and turn the air conditioning system on to check
that the radiator cooling fan operate and to check for coolant leaks from the
radiator or hoses.

cold start.
Confirm that the fan is operating by checking the fan sound and air flow. If it is
difficult to check these, turn the air conditioning system on and off repeatedly. (The
fan may not operate in freezing temperatures.)
7 If the fan is not operating: Stop the hybrid system immediately and contact
your Lexus dealer.
If the fan is operating: Have the vehicle inspected at the nearest Lexus dealer.

Manual" is displayed on the multi-information display.
If the message does not disappear: Stop the hybrid system and contact your Lexus
dealer.
If the message is not displayed: Have the vehicle inspected at the nearest Lexus
dealer.
