With the garage door opener positioned properly and the right number of pegs in place, you should only have to press the button lightly to operate the opener.

Temperature and Compass Display


Object Number: 808605  Size: B3

The outside air temperature and the compass are displayed at the front of the overhead console. The buttons are located to the left of the display.

ON/OFF: Press this button to turn the display on or off.

US/MET: Press this button for the temperature to be displayed in either degrees Farenheit (English) or Celsius (metric).

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 when you turn on the ignition, the word ICE will appear on the display. 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, when your vehicle is new, the compass may function erratically. If it does, CAL (Calibration) will appear on the display. To correct the calibration, drive in a complete 360° circle three times and the compass will function normally.

Variance is the different 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:


Object Number: 806305  Size: B4
  1. Find your location on the zone map. Record your zone number.
  2. Press and hold both the ON/OFF and the US/MET buttons. The display will go off.
  3. After five seconds, VAR CAL (Variance Calibration) will appear on the display. When it does, release both buttons.
  4. Press US/MET until your zone number appears on the display.
  5. Press ON/OFF to enter your zone number. Your variance is now set.

Sunglasses Storage Compartment


Object Number: 808848  Size: B3

The overhead console has a sunglasses storage compartment.

Driver Information Center (DIC)

If your vehicle is equipped with a Driver Information Center (DIC), this system displays the outside air temperature, compass direction and trip information in the overhead console.

US/MET (United States/Metric): The US/MET (United States/metric) button allows you to switch the display between the English and metric system.

MODE: The MODE button can be used to toggle between three modes of operation: OFF, COMP/TEMP and TRIP.

COMP/TEMP (Compass/Temperature): 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 ICE and the current temperature every eight seconds. This is a warning to the drive 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 the holding the MODE and US/MET buttons at the same time 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 different 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:


Object Number: 806305  Size: B4
  1. Find your location on the zone map. Record 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 set your zone number. Your variance is now set and the display will return to the COMP/TEMP mode.
TRIP: Once in the TRIP mode, press the MODE button for the following trip functions:

AVG ECON (Average Economy): The average fuel economy since the last reset is displayed.

INST ECON (Instantaneous Economy): 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 (Average 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 briefly 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 at the same time.
