Instrumentation
Battery voltage gauge (if equipped)
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 (if equipped)
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 "H" and "L").
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.
Add oil if needed (refer to Engine
oil in the Maintenance and care chapter). If the oil level is correct,
have your vehicle checked at your dealership or by a qualified
technician.

works when the ignition is in the
ON position.
