Worth knowing about the 2023 WRX
- Wipers. The front arms use a push-button mount rather than a hook, so choose blades listed for this model rather than by length alone.
- LED lighting. The low beam, high beam, fog light, daytime running, brake light, tail light, reverse light are sealed LED units with no user-replaceable bulb. A failure means replacing the assembly.
- Bulbs. The 7444NA front turn bulb is for models without LED front turn signals; the rest of the exterior lighting is sealed LED.
- Spare. This vehicle carries a compact (temporary) spare, size 205/50R17. Search Amazon for spare tires →
- Tire chains. The manual restricts tire chains on this vehicle. The limits are in the next note; read them before you fit anything.
- Tires. The manual says tire chains cannot be used, and a non-chain SAE Class S traction device goes on the front wheels only if its maker recommends it.
- Torque. Tighten lug nuts to 89 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.
- TPMS. New sensors on this car will not pair on their own by driving; they need a relearn. Method: tool.
- Key fob. Trims without push-button start use a key with a remote head that takes a CR1620.
- Roof load. The 88 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 limit covers crossbars, carrier and cargo together, and the manual says not to fit a roof tent.
- Octane. The manual recommends 91 octane for full performance and allows 87. 87 will not harm the engine; the higher grade is a choice, not a requirement.
