Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from overheat-
ing when there is frequent steering input over an extended period of time. The steer-
ing wheel may feel heavy as a result. Should this occur, refrain from excessive
steering input or stop the vehicle and turn the engine <hybrid system> off. The effec-
tiveness will improve after a short while.
CAUTION
■
The ABS does not operate effectively when
●
The limits of tire gripping performance have been exceeded (such as excessively
worn tires on a snow covered road).
●
The vehicle hydroplanes while driving at high speed on wet or slick roads.
■
Stopping distance when the ABS is operating may exceed that of normal condi-
tions
The ABS is not designed to shorten the vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in front of you, especially in the following situa-
tions:
●
When driving on dirt, gravel or snow-covered roads
●

■
TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slippery
road surfaces, even if the TRAC system is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
■
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may cause
an accident. Exercise particular care when the indicator light flashes.

When the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to ensure vehicle stability and driving force, do not turn the
TRAC/VSC systems off unless necessary.
