Battery voltage gauge
This gauge shows the battery
voltage when the ignition is in the
ON position. If the pointer moves
and stays outside the normal
operating range (as indicated),
have the vehicle's electrical system
checked as soon as possible.
Engine oil pressure gauge
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle
remains in the normal range (the
area between the ªHº and ªLº).
If the gauge indicates low
pressure, switch off the engine
immediately. Check the oil level.
Add oil if needed (refer to
Checking and adding engine oil
in theMaintenance and care
chapter). If the oil level is correct,
have your vehicle checked at your
dealership or by a qualified
technician.
