What to do in an emergency
8 6
6.If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.
7.Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
call an authorized EQUUS dealer
for assistance.
CAUTION
Serious loss of coolant indicates
there is a leak in the cooling sys-
tem and this should be checked
as soon as possible by an
authorized EQUUS dealer.
