Manual says:If either lamp illuminates when the engine
is running, this indicates a malfunction. The
engine will continue to run but it may have
limited power. If it flashes when you are
driving, reduce the speed of your vehicle
immediately. If it continues to flash, avoid
heavy acceleration or deceleration. Have
the system checked by an authorised
dealer immediately.
WARNING
Have this checked immediately.
If both lamps illuminate together, stop your
vehicle as soon as it is safe to do so
(continued use may cause reduced power
and cause the engine to stop). Switch the
ignition off and attempt to restart the
engine. If the engine restarts have the
system checked by an authorised dealer
immediately. When the engine does not
restart have your vehicle checked before
continuing your journey.
