Check Radiator System
If there is a problem with the
radiator system, you will see a
''CHECK RADIATOR SYSTEM'' on
the multi-information display.
If you see this message, the engine
has probably overheated. You should
take your vehicle to a dealer, and
have it repaired as soon as possible.
You can still drive your vehicle even
if this message appears on the multi-
information display, however you
should check the temperature gauge
while driving.
If you notice the temperature gauge
climbing to or above the red mark,
safely pull to the side of the road.
Follow the instructions on pages
497 and 498 .
