Vehicle Operation and Maintenance Flashcards

How does an anti-lock braking system (ABS) change how you should brake in an emergency?

Answer: Press and hold the brake pedal firmly; do not pump the brakes

ABS automatically pulses the brakes to prevent wheel lockup, so the driver should apply steady, firm pressure.

What routine maintenance most directly extends the life of your engine?

Answer: Changing the oil and oil filter at recommended intervals

Clean oil lubricates and protects internal engine parts, making regular oil changes the most important engine maintenance.

Why do batteries fail more often during Alaska winters?

Answer: Cold temperatures reduce battery cranking power while the engine needs more power to start

A battery can lose a large share of its cranking capacity in subzero cold just when thickened oil makes the engine harder to turn over.

If your headlight fails while driving at night, you should:

Answer: Slow down, use your remaining lights, and get the headlight repaired as soon as possible

Driving with one headlight reduces visibility and is illegal, so slow down and repair it promptly.

What does the temperature warning light or gauge in the red zone indicate?

Answer: The engine is overheating and you should stop driving as soon as safely possible

A red-zone temperature reading means the engine is overheating and continuing to drive can cause severe engine damage.

When jump-starting a dead battery, the final connection should be made to:

Answer: An unpainted metal surface on the dead vehicle's engine, away from the battery

Grounding the last cable away from the battery prevents sparks from igniting hydrogen gas that batteries can emit.

Why should you warm up and gently test your brakes after driving through deep water or slush?

Answer: Wet brakes can lose stopping power, and light braking dries them out

Water on brake components reduces friction temporarily, and light brake application while moving dries and restores them.
