394 Winter driving An anti-lock brake system (ABS) en- hances your vehicle’s braking perfor- mance on snowy and icy roads. For information on braking on slippery sur- faces, refer to “ABS (Anti-lock Brake System)” FP323 and “Vehicle Dynamics Control system” FP325. WARNING Do not use the cruise control on slippery roads such as snowy or icy roads. This may cause loss of vehi- cle control. CAUTION Avoid prolonged continuous driving in snowstorms. Snow will enter the engine’s intake system and may hinder the airflow, which could re- sult in engine shutdown or even breakdown. !
