Your vehicle is equipped with plastic headlight lenses
that are lighter and less susceptible to stone breakage
than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other abrasive materials to clean the lenses.
Daytime Running Lights (Canada Only and Fleet
Vehicles)
The headlights on your vehicle will illuminate when the
engine is started and the transmission is in any gear
except park. This provides a constantLights ONcon-
dition until the ignition is turned OFF. The lights illumi-
nate at less than 50% of normal intensity. If the parking
brake is applied the Daytime Running Lights will turn
off.

Recalibrating The Compass
Turn on the ignition and set the display to “Compass/
Temperature.” Press and hold the RESET button to
change the display between VAR (compass variance) and
CAL (compass calibration) modes. When the CAL sym-
bol is displayed complete one 360° turn in an area free
from large metal objects or power lines. The CAL symbol
will turn off and the compass will function normally.
Compass Varianceis the difference between magnetic
north and geographic north. In some areas of the country,
the difference between magnetic and geographic north is
great enough to cause the compass to give false readings.
If this occurs, the compass variance must be set according
to the Compass Variance Map.
148 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE:The default for the compass variance is zone 8.
To set the variance: Turn the ignition ON and set the
display to “Compass/Temperature.” Press and hold the
RESET button approximately five seconds. The last vari-
ance zone number will be displayed. Press the STEP
button to select the new variance zone and press the
RESET button to resume normal operation.
Outside Temperature
Because the ambient temperature sensor is located un-
derhood, engine temperature can influence the displayed
temperature, therefore, temperature readings are slowly
updated when the vehicle speed is below 20 mph (30
km/h) or during stop and go driving.
