Worth knowing about the 2026 K4

  • Connector. Both front blades use a j-hook connector. A blade of the right length with the wrong connector will not clip on, so check the connector before you buy.
  • Wipers. The 2026 hatchback's rear blade was not confirmed by two blade makers.
  • LED lighting. The low beam, high beam, fog light, daytime running, front turn signal, license plate, dome / map light are sealed LED units with no user-replaceable bulb. A failure means replacing the assembly.
  • Spare. This vehicle carries a compact (temporary) spare.
  • Tire chains. The manual permits tire chains or cables of SAE Class S (low clearance), 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. Chains are not allowed on 235/40R18 tires; the compact spare (T125/80D15 or T125/80D16) is fitted on some models, others carry a tire mobility kit.
  • Wheels. The manual gives wheel lug nut torque as a range, 79 to 94 lb-ft (11 to 13 kgf-m), rather than a single figure.
  • Key fob. The folding key takes a CR2032 and the smart key a CR2450.
  • Dimensions. The figures above are for the 4-door sedan, 2.0L on 16- or 17-inch tires; other body configurations differ in length, wheelbase and weight.
  • Dimensions. The 2026 hatchback is 174.4 inches long.
