RUNNING-IN

Running-in period

The following guide-lines will be useful in obtaining optimum performance from your new Jaguar. Jaguars are built using high-precision manufacturing methods but the moving parts of the engine must still bed in relative to one another. This process occurs mainly in the first 3,000 km (2,000 miles) of operation.

During this Running-in period of 3,000 km
(2,000 miles) you should:
• Avoid frequent cold starts followed by
short-distance driving.
• Preferably take longer trips.
• Do not use full throttle during starts and
normal driving.
• Avoid continuous operation at high engine
speed and abrupt stops.
• Do not participate in track days, sports
driving schools or similar.
In addition specifically up to 2,000 km (1,200
miles):
• Drive at varying engine and road speeds,
but do not exceed an engine speed of 4500
rpm (revolutions per minute) and a road
speed of 170 km/h (105 mph).

From 2,000 km (1,200 miles) to 3,000 km (2,000 miles):
• Engine and road speeds can be increased
gradually.
• Engine speeds in excess of 5000rpm
should only be used briefly e.g. when
overtaking.
At all times, not just during the Running-in
period:
• Do not exceed 4,000 rpm until the engine
has reached full operating temperature.
• Avoid labouring the engine by operating
the engine in too high a gear at low speeds.
