RUNNING-IN
During the first 1,200 miles (2,000 kilometres), avoid over-revving,
and do not let the needle reach the coloured marks of the
corresponding speed ranges, before changing gear. Also avoid
during this period:
-harsh acceleration,
-fierce braking (the brake linings must be run in),
-long journeys at constant speed,
-labouring the engine at too low a speed.
SERVICING AND GUARANTEE
At the time of delivery, you will be given a "Maintenance Guide",
with a "Guarantee Card" and a 600 miles (1,000 km) "Servicing
Certificate".
On completion of the first 600 miles (1,000 km), any Citroën dealer,
whether he supplied the vehicle or not, will service the car, free-of-
charge, on presentation of this "Maintenance Guide".
It is particularly important that the oil filter cartridge, which has to
comply to the standard regulations, should be of the type
recommended by Citroën.
Only the cost of the materials used will be charged for.
The dealer will keep the Servicing Certificate and sign the
Guarantee Card.
