Answer
Pneumatic tyres: The tyres are fitted with a car tyre valve. They can be inflated using the pump supplied. Make sure not to exceed the maximum pressure of 1.8 Bar. Also make sure that all tyres are inflated sufficiently and equally (at least 1.5 Bar, maximum of 1.8 Bar/26 PSI) to ensure the pushchair is comfortable to push and to prevent premature wear and tear. Hard parts: The frame and wheels on the Maxi-Cosi pushchairs are easy to clean. Remove all dirt, mud and other debris using a damp cloth. Do not use silicon lubricants, as they will attract dirt and grime. Use a dry Teflon spray instead. Fabrics: The fabric parts of the Maxi-Cosi pushchairs must be washed by hand.
