5-2. Steps to take in an emergency Check that the coolant level of the power control unit is between the "FULL" and "LOW" lines of the reservoir tank. "FULL" line "LOW" line If the coolant level of the power control unit is insufficient, add more coolant. If power control unit coolant is unavailable, water can be used as an emergency substitute. Restart the hybrid system (depress and hold the brake pedal, and press the "POWER" switch once). Check that the "HYBRID SYSTEM OVERHEAT" message has gone off. If the warning message remains on, stop the hybrid system and contact your Lexus dealer. Have the vehicle inspected at the nearest Lexus dealer as soon as possible.

5-2. Steps to take in an emergency
Check that the coolant level of the
power control unit is between the
“FULL” and “LOW” lines of the
reservoir tank.
“FULL” line
“LOW” line
If the coolant level of the power
control unit is insufficient, add
more coolant.
If power control unit coolant is
unavailable, water can be used as
an emergency substitute.
Restart the hybrid system (depress and hold the brake pedal, and
press the “POWER” switch once). Check that the “HYBRID
SYSTEM OVERHEAT” message has gone off.
If the warning message remains on, stop the hybrid system and
contact your Lexus dealer.
Have the vehicle inspected at the nearest Lexus dealer as soon as possi-
ble.
■

●
