For all-wheel drive: If you install snow tires, they must also be the same size, brand, construction and tread pattern on all four wheels. TIRE EQUIPMENT 1. SUMMER tires are of a tread design to provide superior performance on dry pavement. However, the performance of these tires will be substantially reduced in snowy and icy conditions. If you operate your vehicle on snowy or icy roads, INFINITI recommends the use of MUD & SNOW or ALL SEASON tires on all four wheels. Please consult an INFINITI dealer for the tire type, size, speed rating and availability information. 2. For additional traction on icy roads, studded tires may be used. However, some provinces and states prohibit their use. Check local, state and provincial laws before installing studded tires. Skid and traction capabilities of studded snow tires, on wet or dry surfaces, may be poorer than that of non-studded snow tires. ANTI-FREEZE In the winter when it is anticipated that the temperature will drop below 32°F (0°C), check anti-freeze to assure proper winter protection. For additional information, see "Engine cooling system" in the "8. Maintenance and do-it-yourself" section. SPECIAL WINTER EQUIPMENT It is recommended that the following items be carried in the vehicle during winter: a scraper and stiff-bristled brush to remove ice and snow from the windows and wiper blades. a sturdy, flat board to be placed under the jack to give it firm support. a shovel to dig the vehicle out of snow-drifts. extra window washer fluid to refill the reservoir tank. BATTERY If the battery is not fully charged during extremely cold weather conditions, the battery fluid may freeze and damage the battery. To maintain maximum efficiency, the battery should be checked regularly. For additional information, see "Battery" in the "8. Maintenance and do-it-yourself" section.
