Dashboard warning lights: Trouble with the lights

Summary:

A recent poll by Diono, a Canadian car-seat maker, revealed troubling findings about drivers’ understanding of dashboard warning lights. The survey of 2,000 Canadian drivers showed that just over 50% find these dashboard warning lights confusing and are uncertain about their meanings. Alarmingly, only 26% would stop driving immediately when a warning light appears; others might continue driving, search online, or take the car to a shop. Nearly 30% admitted to ignoring a warning light at least once, despite these lights often indicating crucial safety systems like anti-lock brakes or airbags.

The lack of a universal standard for warning light symbols complicates matters. Different automakers use varying shapes, sizes, and colors for the same warning, making it challenging for drivers to quickly understand what each light signifies. With advancements in technology, car manufacturers have the capability to improve warnings with clearer, more understandable language, but many still rely on confusing symbols.

The most critical warning light is often the ‘check engine’ light, which can indicate either minor or serious issues. A minor fault, like an oxygen sensor problem, may not trigger the light but can still cause significant engine damage if ignored. Many drivers avoid checking warning lights due to fears of high repair costs.

To better manage warning lights, drivers should refer to their vehicle’s owner’s manual or a printed guide explaining each icon’s meaning. Keeping this guide in the glove box ensures quick access. Familiarizing oneself with these symbols can prevent costly repairs and improve safety. For older vehicles, a code reader might help diagnose issues before visiting a mechanic.
