If a tire goes flat while you’re driving:p. 81

  • Don’t brake right away.p. 81

Brake, steering or headlight failure

  • Brakes fail completely: with the wheels straight, carefully use the park brake to slow down. Shifting to a lower gear may help you stop safely.p. 80
  • After any brake problem, park somewhere safe and don’t drive until the brakes are checked and repaired.p. 81
  • Power steering fails: you can still steer, with extra effort.p. 81
