Vehicle maintenance resources and checklists
This page gives private owners and fleet managers ready-to-use checklists and quick-reference facts for keeping cars roadworthy, safe and cost-efficient. Use the steps below before each service, between service intervals, and when preparing multiple vehicles for the year ahead. Everything here is written to be printed, saved or worked through in a few minutes.
Pre-service preparation checklist
- Note your current mileage and compare it against the manufacturer's service schedule to confirm which interval is due (oil, filters, timing belt, brake fluid).
- Gather the service booklet or digital maintenance history so the garage can see what was last replaced and when.
- Check dashboard warning lights before your appointment and photograph any that stay on so you can describe them accurately.
- List recurring symptoms — unusual noises, vibrations, pulling to one side, longer braking distances — with when and how often they occur.
- Check tyre tread depth with a coin or gauge (legal minimum in France is 1.6 mm) and note uneven wear.
- Top up and inspect fluids at a glance: engine oil level, coolant, washer fluid, and look for leaks under the car.
- Confirm your contrôle technique (CT) expiry date so any due repairs can be handled in the same visit.
- Ask for a written estimate before authorising work and keep it for your records.
Fleet maintenance planning checklist
- Build a single register listing each vehicle's make, model, registration, mileage and last service date.
- Set mileage-based and time-based reminders per vehicle so high-usage cars are not missed between calendar intervals.
- Standardise service intervals across identical models to simplify parts ordering and scheduling.
- Track cost per vehicle (servicing, tyres, repairs, fuel) to spot units that are becoming uneconomical to keep.
- Schedule tyre changes ahead of the winter period, especially for vehicles operating in mountain or snow zones subject to the Loi Montagne rules.
- Keep a spare-vehicle or rotation plan so servicing does not interrupt operations.
- Store all invoices and contrôle technique certificates centrally for compliance and resale value.
- Review the fleet quarterly to plan replacements before major repairs fall due.
Quick reference
- Contrôle technique is mandatory for cars over 4 years old, then every 2 years, and within 6 months of a sale.
- Legal minimum tyre tread depth in France is 1.6 mm across the central three-quarters of the tread.
- Engine oil and oil filters are typically changed every 10,000–30,000 km depending on engine type and oil grade — check your manual.
- Brake fluid is usually renewed every 2 years regardless of mileage because it absorbs moisture over time.
- Timing belts commonly need replacement between 60,000 and 160,000 km; a failure can cause severe engine damage, so follow the manufacturer's figure.
- Battery lifespan averages 4–5 years, with cold weather and short trips shortening it noticeably.
How do I know when my car is due for a service?
Check the manufacturer's schedule in your service booklet, which sets intervals by both mileage and time (for example every 15,000 km or 12 months, whichever comes first). Many modern cars also display a service reminder on the dashboard. If you are unsure, our consultation can review your history and mileage to confirm what is due.
What is the difference between a service and the contrôle technique?
A service is preventive maintenance — replacing oil, filters and worn parts to keep the car running well. The contrôle technique is a mandatory safety and emissions inspection required by French law at fixed intervals. A car can pass the contrôle technique yet still need servicing, so the two are complementary rather than the same thing.
Should fleet vehicles follow the same schedule as private cars?
The underlying manufacturer intervals are the same, but fleet vehicles often reach mileage thresholds much faster, so time-based reminders alone are not enough. Fleets benefit from a central register and mileage tracking so servicing is triggered by actual use, keeping downtime and repair costs predictable.
Can I delay a recommended repair to spread the cost?
Some items can safely wait a short period, while others — brakes, tyres, steering and anything flagged as a safety defect — should be addressed promptly. Ask for the work to be prioritised into urgent and non-urgent categories so you can plan spending without compromising safety.
What records should I keep for each vehicle?
Keep the service booklet or digital history, dated invoices for all work and parts, contrôle technique certificates, and notes on recurring faults. Complete records support resale value, warranty claims and, for fleets, compliance reporting.
