surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■Hill-start assist control does not operate effectively in some conditions
Do not overly rely on the hill-start assist co ntrol. The hill-start assist control may not

The slip indicator flashes to indicate that ABS, VSC, TRAC or hill-start assist con-

Exercise particular care when the indicator light flashes.

Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to help ensure vehicl e stability and driving force by automati-
cally controlling the brakes and engine ou tput, do not turn the VSC/TRAC systems
off unless necessary.
