Changes or modifications to this system by other than
an authorized service facility could void authorization
to use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
D Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.
D Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the left
or right, hold the transmitter higher, and try again.
D Check to determine if battery replacement or
transmitter resynchronization is necessary.
See the instructions that follow.
D If you’re still having trouble, see your dealer or a
qualified technician for service.
