Keys, Doors, and Windows 2-15
The vehicle alarm system will not
arm if the doors are locked with

2-16 Keys, Doors, and Windows
The system is automatically
disarmed when the vehicle is
started with a valid RKE transmitter
in the vehicle. The RKE transmitter
uses electronic coding that matches
an immobilizer control unit in the
vehicle and automatically disarms
the system. Only a correct
transmitter can be used to turn the
vehicle on.
The security light comes on if there
is a problem with arming or
disarming the theft-deterrent
system.
This light comes on briefly when the
vehicle is turned on. There is a
problem if the engine does not start
and this light stays on.
Turn the ignition off and try again.If the engine still does not start, and
the RKE transmitter appears
undamaged, try the other RKE
transmitter for the vehicle, or place
the RKE transmitter in the
transmitter slot. See
Remote
Keyless Entry (RKE) System
Operation on page 2-2. It may be
necessary to check the fuse. See
Electrical System Overload on
page 10-30. If the vehicle does
start, the first transmitter is bad or if
the vehicle still does not start the
vehicle needs service. See your
dealer.
Do not leave the key or device that
disarms or deactivates the vehicle
theft system in the vehicle.
Exterior Mirrors
Convex Mirrors
{Warning
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.
