PEUGEOT SERVICING
Your vehicle benefits from extended service intervals.
¥ For petrol engines: every 20,000 miles (30 000 km) or every two years.
¥ For direct injection diesel engines: every 12,000 miles (20 000 km) or every two years. The service indicator informs you when each service is due; the point at which it is due is calculated from the last indicator zero reset (see corresponding section). This point is determined by two parameters: - the distance travelled,- the time elapsed since the last service. Note:the distance remaining may be weighted by the time factor, in accordance with the driver's style of driving.
The extension of the service intervals means that the engine oil level must be checked regularly: topping up of the oil between oil changes is normal. It is for this reason that the PEUGEOT network invites you to an intermediate visit between regular services.
The date of this service is not shown by the service indicator. It is to be carried out at least every 10,000 miles (15 000 km) for petrol engines and every 6,000 miles (10 000 km) for direct injection diesel engines.
A PEUGEOT dealer will carry out a quick check, and will top up the levels if necessary (oil, coolant, screenwash up to 2 litres). If the oil level is too low there is a risk of serious damage to the engine: check the engine oil level at least every 2,000 miles (3 000 km) or 3,000 miles (5 000 km), depending on the conditions of use The extended service intervals have been made possible by technical modifications to the vehicles and lubricants:
THUS IT IS ESSENTIAL TO ONLY USE LUBRICANTS WHICH ARE SUITED TO YOUR ENGINE AND RECOMMENDED BY
THE MANUFACTURER (see pages on "Lubricants").
