Engine control or emissions management
In the engine and exhaust system, there are multiple sensors that relay multiple messages to a range of computers. These feedback to a car’s main brain, which in turn passes alerts to the driver. If it turns on, take the car to be inspected at a garage.
Diesel particulate filter
Diesel cars use specially designed filters to trap harmful particulates that are emitted when driving. Like the exhaust, these have a finite operating life, but if this first symbol appears you have the opportunity to regenerate the filter by driving at a speed of 37mph (60km/h) until the symbol disappears.
A wear and tear part for every diesel car, these help start a diesel engine when it’s cold. If the glow plug symbol remains on when driving, it indicates trouble. Happily, it is not a big job for them to be replaced.
Tyre pressure monitoring
If your car has tyre pressure monitoring, it will let you know when one tyre falls to a significantly lower pressure than the other three tyres. So if this symbol appears, check the air pressure of all tyres. The handbook will detail the correct pressure for your vehicle’s tyre size.
Blind Sport Warning
Working as an extra pair of eyes in the back of your head, this system uses sensors to detect when a car is on either side of your vehicle. The orange symbol will illuminate in the relevant wing mirror, and an alert may sound should you indicate to change lanes.
If you see this icon it means your car is due for routine servicing, though this may be an oil and filter change or a service — a dealer can confirm which it is. The symbol will most likely be accompanied by a sum of mileage or number of days that will count down to when the service should be performed.
Vehicle Stability Assist
All new Hondas are fitted with a sophisticated system – Vehicle Stability Assist (VSA) – that can help prevent your car from skidding. If this symbol appears, it could be that VSA has been switched off by the driver or an inspection may be required.
Lane Departure Warning System
Acting as an extra pair of eyes on the road ahead, the Lane Departure Warning System alerts the driver when the car is straying from its lane. You’ll generally see this symbol when the system is in use.
