  • Bulbs. The 7440 daytime running light bulb is for cars with bulb-type daytime running lights; LED daytime running lights are sealed units.
  • No spare. This vehicle shipped without a spare tire; it carries an inflator and sealant kit instead. Keep the kit in date, or carry a compact spare. Search Amazon for inflator kits →
  • Tire chains. The manual permits tire chains or cables, within limits on which tires and which wheels. Those limits are in the next note; read them before you fit anything. Search Amazon for tire chains →
  • Tires. The manual allows chains on the rear tires only.
  • Wheels. The manual gives a lug nut torque range of 80 to 108 lb-ft.
  • Dimensions. The figures above are for the Soft top, 16-inch wheels, manual transmission; other body configurations differ in length, wheelbase and weight.
