Reduced effectiveness of the EPS system

The effectiveness of the EPS system is reduced to prevent the system from over-

heating when there is frequent steering input over an extended period of time. The

steering wheel may feel heavy as a result. Should this occur, refrain from excessive

steering input or stop the vehicle and turn the engine off. The EPS system should

return to normal within 10 minutes.

■

Automatic deactivation of °Sport± mode

When the “ENGINE START STOP” switch is turned off after driving in “Sport”

mode, the mode is automatically deactivated.

■

If the slip indicator comes on
