The McLaren 12C should undergo a service check every 10,000 miles or once a year, whichever comes first. This includes oil and filter changes, brake inspection, and other routine checks.
First, check the battery connections and ensure they are tight and free of corrosion. If the battery is fine, inspect the fuses related to the ignition system. If these are all in order, it may be necessary to consult a McLaren technician.
McLaren recommends using a fully synthetic 5W-40 engine oil for optimal performance and protection under various driving conditions.
To improve fuel efficiency, maintain a steady speed, avoid rapid acceleration, ensure tires are properly inflated, and keep up with regular maintenance, including air filter and spark plug replacements.
Check the transmission fluid level and quality. If low or degraded, replace it with the appropriate fluid as per McLaren’s specifications. If the issue persists, seek professional diagnostics as it may require recalibration or repair.
To reset the TPMS, inflate all tires to the recommended pressure, then drive the vehicle at a speed above 20 mph for at least 10 minutes. The system should automatically recalibrate.
Common brake issues include squeaking or grinding noises, which can be resolved by inspecting and replacing worn brake pads, and ensuring the rotors are in good condition. Regular brake fluid changes are also recommended.
Use a pH-neutral car shampoo and a microfiber wash mitt to prevent scratches. Regularly apply a high-quality wax for protection and a ceramic coating for enhanced durability. Avoid automated car washes that might damage the finish.
Check the refrigerant level first and refill if necessary. Clean or replace the cabin air filter and ensure the condenser is free of debris. If the problem persists, there may be an issue with the compressor or other components that require professional attention.
Updates for the navigation system can usually be done via a USB drive. Visit the McLaren website or contact a dealership for the latest software update files and detailed instructions on how to install them.
