Therefore, it is imperative to promptly head to an automotive service center to address this issue before you exhaust your battery’s power completely.

Tyre pressure monitoring warning light

Tyre pressure monitoring warning light

Also recognized as the run-flat indicator (RPA) or low tire pressure warning light.

Modern vehicles often feature tire pressure monitoring systems designed to alert you when tire pressure decreases, whether gradually over time or due to a puncture. This warning light is typically accompanied by an on-screen message specifying the tires that require your attention.

Is it safe to continue driving with the tire pressure light active?

Yes, you can continue driving, but it’s crucial to exercise added caution and prioritize topping up the air at the earliest opportunity. Insufficient tire pressure can lead to hazardous driving conditions, so it’s advisable to reduce your speed and refrain from sudden braking or sharp steering maneuvers.

Most gas stations and service centers offer air compressors for checking and refilling tire pressure. Be sure to follow the vehicle manufacturer’s specifications, as detailed in your owner’s manual, when adding air to your tires.

Oil pressure warning light

OIL

Frequently referred to as the low engine oil or low oil pressure light.

The oil warning light is activated when either the oil temperature rises excessively, or the oil level or pressure drops to a critical low. If the oil fails to provide adequate lubrication to the engine, it can potentially result in costly or even irreversible engine damage, underscoring the urgency of immediate action.
