 and → ATF temperature: 40 degrees Celsius . An ATF inspection when

the temperature is too high causes insufficient filling, while an inspection when the temperature is too low
causes over-filling. The selector lever must be in position "P" and the engine must be idling. The air
conditioning must be switched off. The vehicle must stand horizontally.
