WARNING!
Vehicle exhaust contains carbon monoxide, a danger-
ous gas. Do not run your vehicle in the garage while
training the transceiver. Exhaust gas can cause seri-
ous injury or death.
Programming HomeLinkT
Before You Begin
If you have not trained any of the HomeLinktbuttons,
erase all channels before you begin training.
To do this, press and hold the two outside buttons for 20
seconds. The EVIC will display ªCLEARING CHAN-
NELS.º Release the buttons when the EVIC message
states ªCHANNELS CLEARED.ºIt is recommended that a new battery be placed in the
hand-held transmitter of the device being programmed
to HomeLinktfor more efficient training and accurate
transmission of the radio-frequency signal.
Your vehicle should be parked outside of the garage
while training.
1. Turn the ignition switch to the ON/RUN position.
2. Place the hand-held transmitter 1 to 3 in (3 to 8 cm)
from the HomeLinktbuttons while keeping the EVIC
display in view.
For optimal training, point the battery end of the hand-
held transmitter away from the HomeLinkt.
3. Simultaneously, press and hold both the chosen
HomeLinktbutton and the hand-held transmitter button
until the EVIC display changes from ªCHANNEL #
TRAININGº to ªCHANNEL # TRAINED.º

Then release both the HomeLinktand hand-held trans-
mitter buttons.
If the EVIC display states ªDID NOT TRAINº repeat Step
3. If the signal is too weak, replace the battery in the
original hand-held transmitter.
It may take up to 30 seconds, or longer, in rare cases. The
garage door may open and close while you train.
NOTE:Some gate operators and garage door openers
may require you to replace Step 3 with procedures noted
in the ªGate Operator/Canadian Programmingº section.
4. Press and hold the just-trained HomeLinktbutton. If
the channel has been trained, the EVIC display will now
state ªCHANNEL # TRANSMIT.º
If the EVIC display still states ªCHANNEL # TRAIN-
INGº repeat Step 3.NOTE:After training a HomeLinktchannel, if the
garage door does not operate with HomeLinktand the
garage door opener was manufactured after 1995, the
garage door opener may have rolling code. If so, proceed
to the heading ªProgramming A Rolling Code System.º
5. PROGRAMMING A ROLLING CODE SYSTEM
At the garage door opener motor (in the garage), locate
the ªlearnº or ªtrainingº button.
This can usually be found where the hanging antenna
wire is attached to the garage door opener motor (it is
NOT the button normally used to open and close the
door).

3.Without releasing the button,proceed with Program-
ming HomeLinktStep 2 and follow all remaining steps.
Security
It is advised to erase all channels before you sell or turn
in your vehicle.
To do this, press and hold the two outside buttons for 20
seconds until the EVIC message states ªCHANNELS
CLEARED.º Note that all channels will be erased. Indi-
vidual channels cannot be erased.
The HomeLinktUniversal Transceiver is disabled when
the Vehicle Security Alarm is active.
Troubleshooting Tips
If you are having trouble programming HomeLinkt, here
are some of the most common solutions:
²Replace the battery in the original transmitter.
²Press the learn button on the garage door opener to
complete the training for rolling code.
²Did you unplug the device for training, and remember
to plug it back in?

There is an additional power outlet inside the center
console of vehicles equipped with 40-20-40, or Bucket
front seats. There is also a power outlet located on the
rear of the center console for Quad Cabtor Mega Cabt
vehicles (only) equipped with bucket seats.
The outlet(s) has/have a fused direct feed from the
battery so it/they receive power whether the ignition is
ON or OFF.
All accessories connected to this/these outlet(s) should
be removed or turned OFF when the vehicle is not in use
to protect the battery against discharge.
NOTE:If desired, all of the power outlets can be
converted by your authorized dealer to provide power
with the ignition switch in the ON position only.CAUTION!
Electrical Outlet Use With Engine Off
²Many accessories that can be plugged in draw
power from the vehicle's battery, even when not in
use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle's battery will
discharge sufficiently to degrade battery life
and/or prevent engine starting.
²Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these inter-
mittently and with greater caution.
²After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle's battery.

Push the upper button on the front of the armrest to raise
the upper cover. Inside is a power outlet (if equipped), a
cutout for a cell phone charger cord, removable coin
holder (if equipped), and a divider to configure the

storage area into separate compartments. Lift the lower
handle on the front of the armrest, and raise the armrest
for access to the lower storage bin. On Quad Cabtand
Mega Cabtmodels the rear of the floor console offers a
power outlet, a tip out bin and a rear air duct (Mega Cabt
Only).
WARNING!
²This armrest is not a seat. Anyone seated on the
armrest could be seriously injured during vehicle
operation, or an accident. Only use the center
seating position when the armrest is fully upright.
²In an accident, the latch may open if the total
weight of the items stored exceeds about 10 lbs (4.5
kg). These items could be thrown about endanger-
ing occupants of the vehicle. Items stored should
not exceed a total of 10 lbs (4.5 kg).

INSTRUMENT CLUSTER DESCRIPTION
1. Check Gauges
This light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gauges indicate a reading either too high or too low.
Examine the gauges carefully, and follow the instructions
contained below for each indicated problem.
NOTE:When the ignition switch is turned to OFF, the
Fuel Gauge, Voltmeter, Oil Pressure and Engine Coolant
Temperature gauges may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltmeter
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. Ifthe pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced.
NOTE:If the gauge pointer moves to either extreme of
the gauge, the ªCheck Gaugesº indicator will illuminate
and a single chime will sound.
NOTE:
²The voltmeter may show a gauge fluctuation at vari-
ous engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of
the cycling operation is controlled by the engine
control module. Post-heat operation can run for sev-
eral minutes, and then the electrical system and volt-
meter needle will stabilize.
²The cycling action will cause temporary dimming of
the headlights, interior lights, and also a noticeable
reduction in blower motor speed.
