mal and no need for concern .
If the engine does not start immediate ly, stop
trying after 10 seconds and then try to restart
the engine about 30 seconds later .
A WARNING
-Never start or let the engine run in a con-
f ined or enclosed area. Exhaust fumes
from the engine conta in carbon monoxide,
a colorless and odorless gas. Carbon mon­
oxide can be fatal if inhaled .
- Never leave the engi ne idling unattend­
ed. An unat tended veh icle w ith a runn ing
engine poses a danger of personal injury
or theft .

fe r of power is never completely inter­
r u pted - t he vehicle "creeps". If t he vehi-
cle is stat io nary and the t rans missio n is
~

engaged, the engine should never be
speeded up unintentionally (e.g. manual­ ly from under the hood). Otherwise the
vehicle will immediately start to move -
sometimes even if the parking brake is
firmly applied - risk of an accident!
- Before you or other persons open the
hood and work on a running engine, the
selector lever must be moved to P and
the parking brake applied firmly - risk of
an accident! Follow the warning stickers.

Homelink
Universal remote
control
General information
The HomeLink universal remote control can
be programmed with hand-held transmitters
from existing equipment.
You must first program the Homelink trans­
mitter before you can use the system
~ page 89, Programming the HomeLink
transmitter.
In order to program the Homelink transmit­
ter for devices utilizing rolling code, a second
person on a ladder who can safely reach the
garage door opener motor is recommended.
It is also necessary to locate the "learn" but­
ton on your garage door opener motor . Refer
to the operating instructions for the opener, as the location and color of this button may
vary by manufacturer .
You can still use the origina l remote control
for the device at any time.
A WARNING
-
- Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as requ ired by federal safety stand­
ards. This includes any garage door open­
er model manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards. Using a garage door
opener without these features increases
risk of serious injury or death.
- For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle.
- A garage door or an estate gate may
sometimes be set in motion when the Homelink remote control is being pro­
grammed. If the device is repeatedly ac-
Homelink 89
tivated, this can overstrain motor and
damage its electrical components -an
overheated motor is a fire hazard!
- To avoid possible injuries or property
damage, please always make absolutely
certain that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.
