ENTER/r(Enter):Press this button to select a
menu option or to acknowledge a warning message.
The DIC messages will be read through your audio
system display.
DIC Operation and Displays
The DIC comes on when the ignition is on. If your
vehicle has the uplevel audio system, the time and
outside temperature is shown on the rst line of
the display and the DIC information is shown on the
second line of the display.
The DIC has different modes which can be accessed by
pressing the DIC buttons. The button functions are
detailed in the following section.
Information Modes
INFO/4(Information):Press this button to scroll
through the vehicle information mode displays in the
following order:
TRIP A
TRIP B
FUEL RANGE (Fuel Range Until Empty)
MPG (L/100 KM) AVG (Average Fuel Economy)
MPG (L/100 KM) INST (Instantaneous Fuel
Economy)
AV SPEED (Average Vehicle Speed)
OIL LIFE (Engine Oil Life System)
Tire Pressure
TRIP A or TRIP B:Press the information button until
TRIP A or TRIP B display. These modes show the
current distance traveled since the last reset for each
trip odometer in either miles (mi) or kilometers (km).
Both odometers can be used at the same time.
To reset the trip odometer to zero, press and hold the
enter button for a few seconds while the desired
trip odometer is displayed.
FUEL RANGE:Press the information button until FUEL
RANGE displays. This mode shows the remaining
distance you can drive without refueling in either miles
(mi) or kilometers (km). It is based on fuel economy
and the fuel remaining in the tank.
When the fuel level is low, FUEL RANGE LOW displays.
The fuel economy data used to determine fuel range
is an average of recent driving conditions. As your
driving conditions change, this data is gradually updated.
The FUEL RANGE mode cannot be reset.

MPG (L/100 KM) AVG (Average):Press the
information button until MPG (L/100 KM) AVG displays.
This mode shows how many miles per gallon (mpg)
or liters per 100 kilometers (L/100 km) your vehicle is
getting based on current and past driving conditions.
To reset the average fuel economy, press and hold the
enter button while MPG (L/100 KM) AVG is displayed.

from that point. If the average fuel economy is not reset,
it is continually updated each time you drive.
MPG (L/100 KM) INST (Instantaneous):Press the
information button until MPG (L/100 KM) INST displays.
This mode shows the current fuel economy at a
particular moment and changes frequently as driving
conditions change. This mode shows the instantaneous
fuel economy in miles per gallon (mpg) or liters per
100 kilometers (L/100 km). Unlike average fuel
economy, this screen cannot be reset.

conditions.
In addition to the engine oil life system monitoring the oil
life, additional maintenance is recommended in the
Maintenance Schedule in this manual. SeeScheduled

Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-14for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it
again, keeping the tip down and check the level.
