Engine Oil Level – Display in Instrument Cluster 
(Vehicles with ASSYST Maintenance Computer only)
If the : indicator lamp lights up briefly when the
engine is running, the engine oil level has dropped to
the minimum mark. Check the engine oil level without
delay and add oil to the upper mark on the dipstick. If no engine oil is added and the engine oil level drops
further, a warning buzzer will also sound and 
will appear in the multi-function indicator. 2.0 quarts
(about 1.9 liters) of oil must be added.
NOTE: Engine oil level display
– "qt" in USA only. 
– "l" in Canada only.
CAUTION!
If the : indicator lamp lights up, the warning 
symbol in the multi-function indicator appears 
and the warning buzzer sounds, the operating 
safety of the engine is endangered (possibility of 
engine damage). 
A sudden decrease or absence of oil pressure may
indicate a mechanical failure. Bring the vehicle to
a safe stop, and investigate the cause to prevent
further damage. Do not operate the engine until
the cause has been determined and corrected.

ENGINE OIL LEVEL INDICATOR IN INSTRUMENT 
CLUSTER 
(VEHICLES WITHOUT ASSYST MAINTENANCE 
COMPUTER)
If the : indicator lamp lights up when the engine is
running, the engine oil level has dropped to the
minimum mark. Check the engine oil level without
delay and add engine oil up to the upper mark on the
dipstick.
If there is no engine oil in the oil sump, a warning
buzzer will sound if the key is turned to position 2 in
the ignition lock or if the vehicle is being driven, and
the warning 
will appear in the multi-function indicator. About 2
quarts (1.9 liters) of oil must be added.
Check the engine oil level without delay and add
engine oil to the upper mark on the dipstick.

CAUTION!
If the : indicator lamp lights up, the warning 
symbol in the multi-function indicator appears 
and the warning buzzer sounds, the operating 
safety of the engine is endangered (possibility of 
engine damage). 
Safely pull off the road and turn off the engine (do
not restart the engine). Determine the cause of the
problem. If there are no obvious signs of leakage,
add engine oil. The engine oil level must be
between the lower and upper marks on the
dipstick. Only add engine oil up to the upper
mark – do not overfill.
If the engine oil level is above maximum, there is
a danger of damage to the engine or catalytic
converter.
