Worth knowing about the 2021 TLX

  • Wipers. The blade connector for this generation was not confirmed, so check the arm before buying.
  • LED lighting. The low beam, high beam, fog light, daytime running, front turn signal, 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.
  • 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. Inflator kits on Amazon →
  • Tire chains. The manual permits chains or cables, on the drive wheels only, fitted to the standard tire size. Chains for this size on Amazon →
  • Tires. Tire chains go on the front tires only (Acura recommends Auto-Trac 0155505 cables), and a T145/60R20 compact spare was optional in place of the repair kit.
  • Torque. Tighten lug nuts to 94 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.
  • Key fob. Match the FCC ID (KR5T21) printed on the back of your fob when buying a replacement; the same car can use two fob designs in one year. A new fob still needs programming to the car.
  • Octane. The manual requires 87 octane and recommends 91 for full performance. Regular will not harm the engine; premium is a choice, not a requirement.
