Warning

•  The EV system is hot immediately after driving and charging, and can cause severe burns. Turn off the EV system and wait until it is cool before performing the servicing.

•  If the cooling system cap is removed while the EV system is hot, hot coolant may be ejected, causing severe burns or injury. Perform the removal of the cooling system cap when the EV system is cool.

•  When removing the cooling system cap, cover the cooling system cap with a clean cloth and remove it slowly.

•  The cooling fan may suddenly start operating regardless of the main power switch position.
