MODE: The MODE button can be used to toggle
between three modes of operation: OFF, COMP/TEMP
and TRIP.
COMP/TEMP: The display provides the outside
temperature and one of eight compass readings to
indicate the direction the vehicle is facing.
Before you turn on the ignition and move the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on. If the outside
temperature is 37
F (3
C) or lower, the display will
toggle between the word ICE and the current
temperature every eight seconds. This is a warning to
the driver that road conditions may be icy, and that
appropriate precautions should be taken.
The compass is self
-calibrating, so it does not need to be
manually set. However, if C (Calibration) is displayed,
the compass will need to be calibrated. You may also
place the compass in a noncalibrated mode by pressing
and holding the MODE and US/MET buttons
simultaneously while in the COMP/TEMP mode. After
about 10 seconds, the compass will display C and you
can release the buttons. Drive the vehicle in a complete
360
circle three times at a speed of less than 5 mph
(8 km/h), and the compass will function normally. Once
the calibration is complete, the display will return to a
compass reading.
Variance is the difference between magnetic north and
geographic north. In some areas, the difference between
the two can be great enough to cause false compass
readings. If this happens, follow these instructions to set
the variance for your particular location:
1. Find your location on the zone map earlier in this
section. Note your zone number.
2. Press and hold both the MODE and the US/MET
buttons in the COMP/TEMP mode.

3. After five seconds, the compass will acknowledge
the variation mode by displaying the current zone
number. When it does, release both buttons.
4. Press US/MET until your zone number appears on
the display.
5. Press MODE to enter your zone number. Your
variance is now set and the display will return to the
COMP/TEMP mode.
TRIP: Once in the TRIP mode, pressing the MODE
button will step you through the following
TRIP functions:

AVG ECON: The average fuel economy since the
last reset is displayed.

INST ECON: Instantaneous fuel economy for the
last second of driving is displayed.
RANGE: The display indicates the estimated
distance that can be travelled with the remaining fuel
in the tank, based on the fuel economy for the last
few hours of driving.

FUEL USED: The fuel used since the last reset
is displayed.

AVG SPEED: The average speed since the last reset
is displayed.
To reset the trip computer, press the MODE and US/MET
buttons simultaneously for at least two seconds. All
functions will be displayed for half a second once the
system is reset. Reset can only be performed in the AVG
ECON, FUEL USED and AVG SPEED modes. All three
modes are reset simultaneously.

2-65 Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has been
driven, in either miles (used in the United States) or
kilometers (used in Canada).
The odometer mileage can be checked without the
vehicle running. Simply press the trip odometer button.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then it must be. But if
it can't, then it's set at zero, and a label must be put on
the driver's door to show the old mileage reading when
the new odometer was installed.
Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
To view the trip odometer, press the button near the
readout. To reset the trip odometer, hold the button until
it resets.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
The tachometer has three areas: normal operating range,
red warning range and red danger range.
The normal operating range shows your engine speed
during normal driving conditions. For example, when
the needle points to 2, it means the engine is running at
2,000 revolutions per minute (rpm). The tachometer
needle will vary all the time that the engine is running.
The shaded red warning range tells you that your engine
speed is reaching its upper limits. Don't drive very long
with the tachometer in the red warning range. Lift your
foot off the accelerator pedal.
The solid red danger range tells you that your engine
speed is at its upper limits. You should immediately
shift to a higher gear, or lift your foot off the
accelerator pedal.
NOTICE:
Do not operate the engine with the tachometer in
the red range, or engine damage will occur.

RECALL: Display the time with the ignition off by
pressing this button. When the radio is playing, press
this button to recall the station frequency.
SCV: Your system has a feature called
Speed
-Compensated Volume (SCV). With SCV, your
audio system adjusts automatically to make up for road
and wind noise as you drive. Set the volume at the
desired level. Turn the control ring behind the upper
knob clockwise to adjust the SCV. Then, as you drive,
SCV automatically increases the volume, as necessary,
to overcome noise at any particular speed. The volume
level should always sound the same to you as you drive.
If you don't want to use SCV, turn the control all the
way down. Each notch on the control ring allows for
more volume compensation at faster vehicle speeds.
