Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.

no fresh air ventilation. For more information, see
Engine Exhaust on page 2-37.

If an abnormal temperature reading is displayed for
an extended period of time, please consult your
dealer/retailer. Under certain circumstances, a delay in
updating the temperature is normal.
Passenger Airbag Indicator
The vehicle may be equipped with a passenger airbag
indicator, on the mirror glass, just above the buttons.

the word ON, or an airbag symbol in Canada, when the
passenger airbag is enabled. For more information,
seePassenger Sensing System on page 1-64.

turn the compass on or off.
Compass Calibration
The compass may need calibration if:
After several seconds, the display does not show a
compass heading (N for North, for example), there
may be a strong magnetic eld interfering with
the compass. Interference can be caused by
a magnetic antenna mount, magnetic note pad
holder or a similar magnetic item.
The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed, press
and hold
Oor depending on the mirror, press COMP
until CAL displays.
The compass can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display
reads a direction.
Compass Variance
The mirror is set to zone eight. If you do not live in zone
eight or drive out of the area, the compass variance
needs to be changed to the appropriate zone.

To adjust for compass variance:
1. Find your current location and variance zone
number on the following zone map.
2. Press and hold
Oor depending on the mirror,
press COMP until a Z and/or a zone number
displays. The compass is now in zone mode.3. Keep pressing
Ountil the desired zone number
displays. Release the button. After several seconds
of inactivity, the new zone number locks in and the
compass display returns.
4. Calibrate the compass as previously described.

vehicles) look farther away than they really are. If
you cut too sharply into the right lane, you could
hit a vehicle on the right. Check the inside mirror
or glance over your shoulder before changing
lanes.
The passenger side mirror is convex shaped. A convex
mirror’s surface is curved so more can be seen from
the driver seat.
