minute and stays on to indicate a system malfunction.

Registration of the position of each wheel after performing a tire rota-
tion

It is necessary to register the position of each wheel after performing a tire
rotation.
Wheel position registration can be performed by oneself. Wheel position registra-
tion is performed by driving forward with moderate left and right turns. However,
depending on the driving conditions and driving environment, registration may
take some time to complete.

Park the vehicle in a safe place, turn the engine switch off and wait 15 minutes
or more.

Start the engine.
