Winter driving instructions The most important rule for slippery or icy roads is to drive sensibly and to avoid abrupt acceleration, braking and steering maneuvers. Do not use the cruise control system under such conditions. When the vehicle is in danger of skidding, shift the automatic transmission to position N. Try to keep the vehicle under control by corrective steering action. i For information on driving with snow chains, see "Snow chains" ( page 406). Warning! G i For information on speed ratings for winter tires, see "Winter tires" ( page 405). For additional general information on tire speed markings on the tire sidewall, see "Tire speed rating" ( page 403). On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle's ABS will not prevent this type of control loss. 354
