Nottinghamshire Fire and Rescue Service issued the warning over the weekend.
The warning comes after the service attended the incident on Saturday 27 May.
The sun had been strong on the day with temperatures reaching a consistent 21 Degrees C for most of the afternoon.
A spokesperson said:
‘The sun has been strong but beware this can cause fire
‘Earlier we attended a fire caused by sunglasses left on the dashboard.
‘Make sure you keep reflective objects out of direct sunlight.’
The warm weather looks set to continue into next week, Met Office Deputy Chief Forecaster, Steven Keates, said:
“Next week is half-term week for much of the country and there is as strong signal the high-pressure will continue to dominate our weather.
“Its exact position over the UK will dictate the temperature, wind direction and weather patterns, however, indications are that the dry, bright weather is likely to continue for most with little in the way of rain throughout next week.”
With the fine weather many of us may be planning to be out and about over the long weekend. Travel experts are warning of a busy time on the roads.
RAC spokesman Rod Dennis said:
“We fully expect families to make the most of the largely fine weather over the coming days which is why we’re forecasting the busiest late May bank holiday since before the pandemic.
“As usual, it’s Friday afternoon and evening that could see some of the worst jams. Into next week and half term for many parts of the UK, day trips will also be a big feature with popular routes to the coasts and countryside becoming busy.
“Getting away early in the morning or delaying trips until the evening are the best way to avoid the inevitable delays.
