Vehicle Operation & Maintenance Flashcards

A chauffeur notices the power steering feels heavier than usual. What is the most likely cause?

Answer: Low power steering fluid

Low power steering fluid reduces hydraulic pressure, making the wheel harder to turn.

What does a flashing yellow check engine light typically indicate compared to a steady one?

Answer: A more serious, potentially catalytic-converter-damaging misfire

A flashing check engine light signals an active misfire severe enough to damage the catalytic converter and requires immediate attention.

When should a chauffeur perform a pre-trip inspection of the limousine?

Answer: Before every trip

A pre-trip inspection before every trip ensures safety systems, lights, fluids, and tires are in proper working order.

What is the recommended action when a vehicle's ABS warning light remains on while driving?

Answer: Have the ABS system inspected by a technician promptly

A continuously illuminated ABS light means the anti-lock system may be disabled, requiring professional diagnosis before relying on it.

Which tire condition is most dangerous at highway speeds for a chauffeur vehicle?

Answer: A tire with tread depth below 2/32 of an inch

Tread below 2/32 inch (the legal minimum) severely reduces wet-road grip and blowout resistance at highway speeds.

A chauffeur smells burning rubber inside the vehicle cabin. What should they do first?

Answer: Safely pull off the road, stop the vehicle, and investigate the source

A burning rubber smell can indicate a brake, belt, or tire issue that could lead to a fire or loss of control if ignored.

How does cold weather typically affect a vehicle's tire pressure?

Answer: Pressure drops approximately 1 PSI for every 10°F decrease in temperature

As air cools it contracts, reducing tire pressure — roughly 1 PSI per 10°F drop — requiring seasonal pressure checks.
