Worth knowing about the 2025 Grand Highlander

  • LED lighting. The low beam, high beam, fog light, daytime running, rear turn signal, brake light, tail light, reverse light, license plate are sealed LED units with no user-replaceable bulb. A failure means replacing the assembly.
  • Bulbs. The 7444NA fits the bulb-type front turn and parking lamps; LED-type lamps are replaced by a dealer.
  • Spare. This vehicle carries a compact (temporary) spare.
  • 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. Chains go on the front tires only, and the manual says they cannot be fitted to the 20-inch tires.
  • Torque. Tighten lug nuts to 103 ft-lbs in a star pattern with a torque wrench, and re-check after the first 50 miles. This figure is from the owner's manual; an impact gun will overshoot it.
  • Roof load. The 154 lb roof limit is the dynamic figure for driving and includes the rack itself. It is not a limit for a rooftop tent when parked; the manual gives no static figure.
  • Roof. The roof load limit applies to grades with roof rails.
  • Fuel. The hybrid models hold 17.2 gallons.
