REPROGRAMMING A SINGLE
H
OMELINK® BUTTON
To reprogram a single HomeLink® button that has
been previously trained, without erasing all the
channels, proceed as follows. Be sure to
determine whether the new device you want to
program the HomeLink® button to has a rolling
code, or non-rolling code.

1. Place the ignition in the ON/RUN position,
without starting the engine.

2. Push and hold the desired HomeLink® button until the HomeLink® Indicator light begins to
flash after 20 seconds. Do not release the
button.
3. Without releasing the button , proceed with
Step 2 in “Programming HomeLink® To A
Garage Door Opener” and follow all remaining
steps.
CANADIAN/GATE OPERATOR
P
ROGRAMMING
For programming transmitters in Canada/United
States that require the transmitter signals to
“time-out” after several seconds of transmission,
see the following. Canadian Radio Frequency (RF) laws require
transmitter signals to time-out (or quit) after
several seconds of transmission – which may not
be long enough for HomeLink® to pick up the
signal during programming. Similar to this
Canadian law, some US gate operators are
designed to time-out in the same manner.
It may be helpful to unplug the device during the
cycling process to prevent possible overheating of
the garage door or gate motor.

1. Place the ignition in the ON/RUN position.

2. Place the hand-held transmitter 1 to 3 inches
(3 to 8 cm) away from the HomeLink® button
you wish to program while keeping the
HomeLink® indicator light in view.
3. Continue to press and hold the HomeLink® button, while you press and release (cycle)
your hand-held transmitter every two seconds
until HomeLink® has successfully accepted
the frequency signal. The indicator light will
flash slowly and then rapidly when fully
trained.
4. Watch for the HomeLink® indicator to change flash rates. When it changes, it is
programmed. It may take up to 30 seconds or
longer in rare cases. The garage door may
open and close while you are programming. 5. Press and hold the programmed HomeLink®
button and observe the indicator light.
NOTE:
If the indicator light stays on constantly,
programming is complete and the garage
door/device should activate when the
HomeLink® button is pressed.
To program the two remaining HomeLink®
buttons, repeat each step for each
remaining button. DO NOT erase the chan -
nels.
If you unplugged the garage door opener/device
for programming, plug it back in at this time.
Reprogramming A Single HomeLink® Button
(Canadian/Gate Operator)
To reprogram a channel that has been previously
trained, follow these steps:

1. Place the ignition in the ON/RUN position.

2. Press and hold the desired HomeLink® button until the indicator light begins to flash after
20 seconds. Do not release the button.
3. Without releasing the button, proceed with “Canadian/Gate Operator Programming”
step 2 and follow all remaining steps.

only be used to adjust the interior temperature of
your vehicle. Voice Command will not work to adjust
the heated seats or steering wheel if equipped.

OPERATING TIPS
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected with
a high-quality antifreeze coolant to provide proper
corrosion protection and to protect against engine
overheating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling
system is functioning properly and the proper
amount, type, and concentration of coolant is
used. Use of the Air Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Ú page 411.

STARTING AND OPERATING147
(Continued)
2. Press and hold the brake pedal while pushing
the ENGINE START/STOP button once.
3. If the engine fails to start within 10 seconds, place the ignition in the OFF position, wait
10 to 15 seconds to allow the starter to cool,
then repeat the “Extended Park Starting”
procedure.
4. If the engine fails to start after eight attempts, allow the starter to cool for at least
10 minutes, then repeat the procedure.
IF ENGINE FAILS TO START
If the engine fails to start after you have followed
the “Normal Starting” procedure and the vehicle
has not experienced an extended park condition
as defined previously, it may be flooded. Push the
accelerator pedal all the way to the floor and hold
it there. Crank the engine for no more than 10
seconds. This should clear any excess fuel in case
the engine is flooded. Leave the ignition key in the
ON/ RUN position, release the accelerator pedal
and repeat the “Normal Starting” procedure.
AFTER STARTING
The idle speed is controlled automatically and will
decrease as the engine warms up.
STARTING THE ENGINE — DIESEL ENGINE
(IF EQUIPPED)
Before starting your vehicle, adjust your seat, both
inside and outside mirrors, and fasten your seat
belts.
The starter is allowed to crank for up to 25-second
intervals. Waiting two minutes between such
intervals will protect the starter from overheating.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a
time. Wait 10 to 15 seconds before trying again.
WARNING!
Never pour fuel or other flammable liquid into
the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
Do not attempt to push or tow your vehicle to
get it started. Vehicles equipped with an auto -
matic transmission cannot be started this
way. Unburned fuel could enter the catalytic
converter and once the engine has started,
ignite and damage the converter and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a start
from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly Ú page 343.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
10 seconds at a time. Wait 10 to 15 seconds
before trying again.
WARNING!
Before exiting a vehicle, always come to a
complete stop, then shift the automatic trans -
mission into PARK and apply the parking
brake.
Always make sure the keyless ignition node is
in the OFF position, key fob is removed from
the vehicle and vehicle is locked.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving chil -
dren in a vehicle unattended is dangerous for
a number of reasons. A child or others could
be seriously or fatally injured. Children should
be warned not to touch the parking brake,
brake pedal or the gear selector.

23_JT_OM_EN_USC_t.book Page 147

STARTING AND OPERATING151
NOTE:Under certain conditions the Stop/Start system
may be temporarily disabled and the engine fan
will run after the engine is turned off to protect the
engine. These conditions are under high load and
high temperature conditions.
COOLING SYSTEM TIPS — AUTOMATIC
T
RANSMISSION
To reduce the potential for engine and
transmission overheating in high ambient
temperature conditions, take the following actions:
City Driving — When stopped, shift the transmis -
sion into NEUTRAL (N) and increase engine idle
speed.
Highway Driving — Reduce your speed.
Up Steep Hills — Select a lower transmission
gear.
Air Conditioning — Turn it off temporarily.
NOTE:If the coolant temperature is too high, the A/C will
automatically turn off.
Do Not Operate The Engine With Low Oil
Pressure
If the Low Oil Pressure Warning Light turns on while
driving, stop the vehicle and shut down the engine
as soon as possible. After the vehicle is safely
stopped, restart the engine and monitor the lamp. If the lamp is still illuminated, shut the engine off,
contact an authorized dealer, and do not operate
the vehicle until the cause is corrected. If the lamp
is no longer illuminated, the engine can be
operated, but should be taken to an authorized
dealer as soon as possible for further inspection.
NOTE:Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is
in the engine. The engine oil level must be checked
under the hood.
Do Not Operate The Engine With Failed
Parts
All engine failures give some warning before the
parts fail. Be on the alert for changes in
performance, sounds, and visual evidence that the
engine requires service. Some important clues are:
Engine misfiring or vibrating severely
Sudden loss of power
Unusual engine noises
Fuel, oil or coolant leaks
Sudden change, outside the normal operating
range, in the engine operating temperature
Excessive smoke
Oil pressure drop
ENGINE BREAK-IN RECOMMENDATIONS —
GASOLINE ENGINE (IF EQUIPPED)
A long break-in period is not required for the engine
and drivetrain (transmission and axle) in your
vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
While cruising, brief full-throttle acceleration within
the limits of local traffic laws contributes to a good
break-in. Wide-open throttle acceleration in low
gear can be detrimental and should be avoided.
The engine oil installed in the engine at the factory
is a high-quality energy conserving type lubricant.
Oil changes should be consistent with anticipated
climate conditions under which vehicle operations
will occur.
For the recommended viscosity and quality grades
see Ú page 424.
CAUTION!
If oil pressure falls to less than normal readings,
shut the engine off immediately. Failure to do so
could result in immediate and severe engine
damage.
