Toyota Camry Hybrid 2018 Owner's Manual page 99

■
Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help
improve fuel efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may differ even
when vehicle operation and driving conditions are the same.
■
Outside temperature display
In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change:
●
When stopped, or driving at low speeds (less than 16 mph [25 km/h])
●
When the outside temperature has changed suddenly (at the entrance/exit
of a garage, tunnel, etc.)
● When "− −" or "E" is displayed, the system may be malfunctioning.
Take your vehicle to your Toyota dealer.
NOTICE
■
To prevent damage to the engine and its components
The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (→P. 519)
