The light may occasionally flicker when the engine is idling or
it may come on briefly after a hard stop. There is no cause for
concern if it then goes out when the engine is accelerated
slightly.
The light may come on when the oil level is extremely low. It
is not designed to indicate low oil level, and the oil level must
be checked using the oil level dipstick.
NOTICE
Do not drive the vehicle with the warning light on even
for one block. It may ruin the engine.
(m) Engine Oil Replacement Reminder Light
This light reminds you when to replace the engine oil.
This light will come on when the ignition key is turned to “ON”
and will go off after about a few seconds.
When you drive for about 8000 km (5000 miles) after the
engine oil replacement, this light illuminates for about 3
seconds and then flashes for about 12 seconds with the
ignition key turned to “ON” position. If you continue driving
without the engine oil replacement, and if the driving range
exceeds
12000 km (7500 miles), the light will come on after the
ignition key is turned to “ON” position. The light will remain on
thereafter.
If the light is flashing, we recommend that you replace the
engine oil at an early opportunity depending on the driving and
road condition. If the light comes on, replace it as soon as
possible. You need to reset the light after the engine oil replacement.
Reset the light by following the procedure below:
1. Turn the ignition key to the “OFF” position with the odometer
reading
shown. (For details, see “Odometer and trip meter” on
page 42.)
2. Turn the ignition key to the “ON” position while holding down
the trip meter reset knob.
Hold down the knob until the light goes off. Before the light
goes off, it illuminates for 3 seconds, flashes for 2 seconds and
illuminates for 1 second.
If the system fails to reset, the light will remain flashing. In this
case, return to step 1 and try again.
(n) Low Fuel Level Warning Light
This light comes on when the fuel level in the tank becomes
very low. Fill the tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the low fuel level warning light may come on earlier than usual.
(o) Low Washer Fluid Warning Light
This light comes on when the fluid level in the tank becomes
very low. Fill the tank as soon as possible.
(p) Key Reminder Buzzer
This buzzer reminds you to remove the key when you open the
driver’s door with the ignition key in the “ACC” or “LOCK”
position.

Altimeter mode
In altimeter mode, the approximate altitude is displayed.
The displayed altitude ranges from −1500 ft. (−500 m) up to
13000 ft. (4000 m).
As the altitude value is converted from the atmospheric
pressure, it can be easily affected by air motion and
temperature, so the indication may vary. The indicated altitude
of a single position may deviate according to the atmospheric
pressure and temperature.
The displayed value is updated every 2 seconds.
RECTIFICATION OF THE ALTITUDE
Rectification is valid only when the correct altitude is known.
