Don't Get Caught Out! 'Start-Stop' System Fines Looming in NZ Heat - Know Your Rights

The 'start-stop' system, also known as auto start-stop, is increasingly common in modern vehicles. It automatically shuts off the engine when the car is stationary (like at traffic lights or in stop-and-go traffic) and restarts it when you release the brake pedal. The intention is to reduce fuel consumption and emissions.
While generally reliable, the 'start-stop' system can be affected by extreme heat. Repeated engine restarts put a strain on components like the battery and starter motor. In hot weather, these components can overheat, leading to malfunctions and potentially damage. Some manufacturers have implemented automatic shut-off features in very high temperatures to protect the system, but not all do.
Here's where things get tricky. New Zealand law dictates that drivers must ensure their vehicle is under control at all times. If a 'start-stop' system malfunction causes a sudden, unexpected restart that leads to a dangerous situation – for example, lurching forward unexpectedly – you could be issued a fine. While $80 is the potential maximum, the severity of the fine would depend on the circumstances and the judgement of the police officer.
- Check Your Car's Manual: The most important step is to understand your vehicle's specific 'start-stop' system. The owner's manual will outline its operation and any limitations, including heat-related warnings.
- Disable the System (If Possible): Many vehicles allow you to disable the 'start-stop' system. This is often a button on the dashboard. If you're driving in very hot weather, consider disabling it to prevent unnecessary restarts.
- Monitor Your Car's Performance: Pay attention to any unusual noises or warning lights. If you suspect a problem with the 'start-stop' system, get it checked by a qualified mechanic.
- Be Extra Vigilant: In hot weather, be particularly attentive when approaching traffic lights or stop signs. Anticipate potential restarts and be prepared to react accordingly.
- Battery Health: Extreme heat can degrade your battery faster. Have your battery checked regularly, especially during summer months.
If you experience any issues with your 'start-stop' system, don't ignore them. Contact your car dealer or a reputable mechanic for diagnosis and repair. Keep records of any maintenance or repairs related to the system.
The 'start-stop' technology is here to stay, and awareness is key to avoiding potential fines and ensuring safe driving. Stay informed about your vehicle's specific system and take proactive steps to mitigate the risks, especially during the hot New Zealand summer.
