®Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-held
transmitters into one built-in device.
HomeLink
®Universal Transceiver:
. Will operate most Radio Frequency (RF)
devices such as garage doors, gates,
home and office lighting, entry door
locks and security systems.
. Is powered by your vehicle’s battery. No
separate batteries are required. If the

VALET HAND-OFF
When you have to leave a key with a valet,
give them the Intelligent Key itself and keep
the mechanical key with you to protect your
belongings.
To prevent the glove box and the trunk from
being opened during valet hand-off, follow
the procedures below.
1. Push the trunk release power cancelswitch to the OFF (cancel) side.
2. Remove the mechanical key from the Intelligent Key.
3. Lock the glove box and the trunk pass- through with the mechanical key.
4. Hand the Intelligent Key to the valet, keeping the mechanical key in your
pocket or bag for insertion into the
Intelligent Key when you retrieve your
vehicle.
See “Trunk lid” (P.3-22), “Glove box” (P.2-
50) and “Trunk pass-through” (P.1-7).
WARNING
. Always have the doors locked while
driving. Along with the use of seat
belts, this provides greater safety in
the event of an accident by helping to
prevent persons from being thrown
from the vehicle. This also helps keep
children and others from unintention-
ally opening the doors, and will help
keep out intruders.
. Before opening any door, always look
for and avoid oncoming traffic.
. To help avoid risk of injury or death
through unintended operation of the
vehicle and or its systems, including
entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets
unattended in your vehicle. Addition-
ally, the temperature inside a closed
vehicle on a warm day can quickly
become high enough to cause a sig-
nificant risk of injury or death to
people and pets.
