The shift lock release is always functional except in the
case of an uncharged or low voltage (less than 9 volt)
battery.
If the vehicle has an uncharged battery or a battery with

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.
Never run the engine in an enclosed area that
has no fresh air ventilation. For more information,

Thevehicle can roll. Do not leave the vehicle when
the engine is running unless you have to. If you
have left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on fairly level ground, always set the parking
brake and move the shift lever to P (Park).
{CAUTION:
If the vehicle has four-wheel drive, it will be free to
roll — even if the shift lever is in P (Park) — if the
transfer case is in N (Neutral). So be sure the
transfer case is in a drive gear — not in N (Neutral).

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.
2-42

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.
Outside Manual Mirrors
Adjust the outside rearview mirrors to see a little of the
side of your vehicle, and the area beside your vehicle.

return to its original position.
2-43

Outside Power Mirrors
Vehicles with outside power mirrors have controls
located on the driver door.
To adjust the mirrors:
1. Turn the control knob left or right to select the
driver’s or passenger mirror.
2. Move the control knob to the left or right or up or
down to position the mirror to see a little of the
outside of the vehicle.
3. After adjusting the position of the mirrors, turn the
knob to the center off position so that the mirrors
do not move.
If the end of travel position in any direction of the mirror
is reached, it will enter a ratcheting mode. This action
is harmless. It is a warning that the mirror can go
no further. To stop this action, back the mirror up by
moving the knob in the opposite direction.
Manually fold the mirrors inward to prevent damage
when going through an automatic car wash. To
fold, push the mirrors toward the vehicle. To return the
mirrors to their original position, push outward.
Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
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.
