Modern vehicles come with an assortment of warning and information lights. It's time to brush up on your car’s other warning signs beyond the regular fuel, oil, water and tyre warning lights before the Easter weekend holiday break.
According to Motor Industry Workshop Association (MIWA) chair Dewald Ranft, the rule of thumb is that red warning lights need immediate action and amber, orange and other colour lights often mean it’s not urgent but you need to set up an appointment with a workshop soon.
Engine management light
While not advisable, it is safe to drive unless this light is flashing while you are driving. A sensor has alerted the engine control unit or something is not right, and this is why this light has come on.
Battery warning light
It is not safe to drive at all if this light is on. It signals the battery is not charging. There may be a problem with the wiring, the alternator or the alternator drive belt. Stop the car and contact your towing service.
Oil level warning light
Do not continue driving. This light comes on when there is no oil pressure in the engine. The cause could be a blocked oil filter or oil pump. Cars need the correct oil pressure to stay lubricated or the engine can be damaged. Top up as soon as possible if a garage is nearby. If the light stays on it means there is a major problem with the oil supply
Brake warning light
If you feel you have to press your brake pedal further than usual, there is a good chance your hydraulic brake circuits have failed. Pull over immediately and get help. If the brake fluid level is fine it could be a sensor problem and it will be safe to drive to a garage.
Anti-lock braking system (ABS) warning light
As long as there are no noises coming from the wheels, it should be safe to continue driving. Check the user manual to be sure and rather have it checked out as soon as possible. Be extra cautious in wet or slippery conditions when this warning light is on.
Low tyre pressure warning light
If your car is fitted with a tyre pressure monitoring system and this light comes on you should immediately stop on a safe part of the road. This could mean uneven tyre pressures or a deflation. Do a physical check of all the tyres to ascertain if there is damage. If there is no damage you can drive the car but proceed to a garage to correct tyre pressures. If the light persists after correction, book into a workshop.
