Matching Transmitter(s) to
Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of
four transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won’t
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
Notice:When replacing the battery, use care
not to touch any of the circuitry. Static from your
body transferred to these surfaces may damage
the transmitter.To replace the battery, do the following:
1. Insert a thin object like a dime to separate the
bottom of the transmitter from the top.
2. Remove the battery and replace it with a new one,
making sure the positive (+) side of the battery is
facing down. Use one Panasonic
®three-volt,
type CR2032, or equivalent battery.
3. Snap the top and bottom together.

Doors and Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked,
the handle will not open it. You increase
the chance of being thrown out of the
vehicle in a crash if the doors are not
locked. So, wear safety belts properly
and lock the doors whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out.
A child can be overcome by extreme
heat and can suffer permanent injuries
or even death from heat stroke. Always
lock your vehicle whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors
can help prevent this from happening.There are several ways to lock and unlock your vehicle.
To unlock your door from the outside, use your key
or remote keyless entry transmitter, if equipped.
