OPERATING INCIDENTS(continued)
On the open road CAUSES REMEDIAL ACTION
•Steering becomes hard to turn. Belt broken. Have the belt replaced.
Lack of oil in pump. Top up the oil (see maintenance
section).
If the problem persists, consult a
Renault Dealer.
• The engine overheats. The coolant
temperature warning light illuminates
(or the gauge needle moves into the
red zone).Water pump: belt stretched or broken.
Faulty engine cooling fan.Stop the vehicle and switch off the
engine. Consult a Renault Dealer.
Coolant leaks. Check the condition of hoses and
clips.
Check the expansion bottle: it should
contain coolant. If it does not, top it
up(having let it cool down). Take care
not to scald yourself. This action is
only temporary: consult your Renault
Dealer as soon as possible.
Radiator
Never fill a hot radiator with cold coolant if a considerable quantity has been lost. After any operation on the
vehicle which has involved even partial draining of the cooling system, it must be refilled with a new mixture
prepared in the correct proportions. Reminder: only products approved by our Technical Department may be
used for this purpose.

variations in temperature.
These traces will disappear rapidly
once the lights are switched on.
