Following the maintenance schedule in your owner's manual greatly reduces the chance of a vehicle problem. Still, you need to know exactly what to do if your brakes fail or a tire blows out while you're moving.

Know the rule

Check your warning lights. A brake warning light means your brakes aren't working properly—don't drive if you see it.

Handbook p. 62 ↗

If your brakes stop working while driving:

  • Use the parking brake—pull the handle or push the pedal slowly so the rear wheels don't lock
  • Be ready to release it if the vehicle starts to skid
  • If that fails, turn off the engine and find a safe place to slow to a stop, off the roadway
  • Don't keep driving without working brakes

Tire blowout

A rapid deflation of air from a tire.

Handbook p. 62 ↗

Which tire blew?

Which tire blew?
TireWhat you'll feel
FrontThe vehicle pulls sharply toward the blowout
RearWobbling, shaking and some pull toward the blowout
Handbook p. 62 ↗

If a tire blows out or suddenly goes flat:

  • Grip the steering wheel firmly and keep the vehicle going straight
  • Take your foot off the accelerator and slow down gradually
  • Don't brake—let the car slow by itself, or brake gently if necessary
Handbook p. 62 ↗

Then:

  • Avoid stopping on the road if at all possible
  • Pull off the road in a safe place and turn on your emergency flashers
  • Have the tire changed and replaced
Handbook p. 63 ↗

Put it into practice

At highway speed your right front tire bangs and the car jerks right. Hold the wheel firmly and keep it straight, lift off the gas without braking, let the car slow down, then pull well off the road and turn on your flashers.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

If your brakes fail while driving, you should first try:
  1. Turning off the engine immediately
  2. Shifting into neutral and coasting
  3. The parking brake, applied slowly
  4. Swerving onto the shoulder at speed

Answer: The parking brake, applied slowly

Use the parking brake, pulling or pressing it slowly to avoid locking the rear wheels and causing a skid.

Handbook p. 62 ↗
If a tire blows out while driving, you should:
  1. Grip the wheel; avoid hard braking
  2. Brake hard immediately to stop quickly
  3. Accelerate to maintain control
  4. Turn sharply toward the shoulder

Answer: Grip the wheel; avoid hard braking

Grip the wheel firmly, ease off the accelerator, and avoid braking hard; let the vehicle slow gradually.

Handbook p. 62 ↗
If you see a brake warning light illuminated on your dashboard, you should:
  1. Pump the brakes to reset the light
  2. Not drive until the issue is checked
  3. Continue driving normally
  4. Only worry if it's flashing red

Answer: Not drive until the issue is checked

The manual advises not to drive if the brake warning light indicates your brakes are not working properly.
