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 “L” and “H”).

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.

TRIP COMPUTER (IF EQUIPPED)

The trip computer tells you about the condition of your vehicle through
a constant monitor of vehicle systems. You may select display features on
the trip computer for a display of status.

The appearance of your vehicle’s trip computer may differ depending on
your vehicle’s option package, but the functions are the same.

The trip computer only operates with the ignition in the ON position.
Trip computer features follow:

Mode control

Each press of the MODE control will
display a different feature as follows:

Average fuel economy. The
display will indicate the vehicle’s
average fuel economy in liters/100
km (or miles/gallon) since the
average fuel economy was last reset.

If you calculate your average fuel
economy by dividing liters of fuel
used by 100 kilometers traveled
(miles traveled by gallons used), your figure may be different than
displayed for the following reasons:
• your vehicle was not perfectly level during fill-up
• differences in the automatic shut-off points on the fuel pumps at

service stations

• variations in top-off procedure from one fill-up to another
• rounding of the displayed values to the nearest 0.1 liter (gallon)
To reset the average fuel economy:

1. Press the MODE control repeatedly until average fuel economy is
displayed (this is the only resettable display).

2. Press the E/M and MODE
controls simultaneously. The display
will illuminate the “AVG” indicator.
While the indicator is lit, release
both controls to reset the average
fuel economy.

Fuel range. This displays the approximate number of kilometers (miles)
left to drive before the fuel tank is empty. The indicated distance to
empty may be inaccurate:
• with sustained, drastic changes in fuel economy (such as trailer

towing), but will eventually recover.

• if the vehicle is started while parked on an incline.
• if less than 30 liters (8 gallons) of fuel is added to the fuel tank.
The fuel range function will flash for 5 seconds at the following distances
based on fuel remaining and fuel economy calculations:
• 80 km (50 miles)
• 40 km (25 miles)
• 16 km (10 miles)
Off. In this mode the display is off.

Outside air temperature

The temperature can be displayed in
Centigrade or Fahrenheit by
pressing the E/M control.

If the outside temperature falls
below 3°C (38°F), the display will
alternate from “ICE” to the outside
temperature at a two second rate
for one minute.

Compass

The compass display is contained in
the overhead console. The vehicle heading is displayed as one of N, NE,
E, SE, S, SW, W and NW.

The compass heading is displayed in average fuel economy modes, fuel
range modes and temperature modes.

The compass reading may be affected when you drive near large
buildings, bridges, power lines and powerful broadcast antenna. Magnetic
or metallic objects placed in or on the vehicle may also affect compass
accuracy. Adjustments may need to be made to the zone and calibration
of the compass.

Compass zone adjustment

1. Determine which magnetic zone
you are in for your geographic
location by referring to the zone
map.

2. Locate the trip computer on the
overhead console.

3. Turn ignition to the ON position.

4. Press and hold both trip
computer controls. After
approximately four seconds, the trip
computer will enter zone setting
mode. Zone setting mode is
indicated when the display lights the
“ZONE” indicator.

5. Release both controls.
Subsequent pressing of either
control will increment the zone.
Press the control repeatedly until the correct zone setting for your
geographic location is displayed on the trip computer.

6. To exit the zone setting mode and save the displayed zone in memory,
release both controls for greater than five seconds.
