Worth knowing about the 2018 Sonic
- Wipers. Rain-X lists the front arms as its I&L type rather than a hook, so choose blades listed for this model rather than by length alone.
- 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. The manual allows chains only on 195/65R15 or 205/55R16 tires, fitted to the front, and forbids them on every other size.
- Torque. Tighten lug nuts to 100 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 (the manual's TPMS sensor matching process with a relearn tool).
- Fuel. The manual gives 10.8 gallons and the brochure 12.2, so the tank is left open.
