Universal Remote System
Programming
This system provides a way to
replace up to three remote control
transmitters used to activate
devices such as garage door
openers, security systems, and
home automation devices.
Do not use this system with any
garage door opener that does not
have the stop and reverse feature.
This includes any garage door
opener model manufactured before
April 1, 1982.Read the instructions completely
before attempting to program the
transmitter. Because of the steps
involved, it may be helpful to have
another person assist with
programming the transmitter.
Be sure to keep the original remote
control transmitter for use in other
vehicles, as well as for future
programming. Only the original
remote control transmitter is needed
for Fixed Code programming.
The programmed buttons should be
erased when the vehicle is sold or
the lease ends. See
“Erasing
Universal Home Remote Buttons”
in this section.
Park the vehicle outside of the
garage when programming a
garage door. Be sure that people
and objects are clear of the garage
door or gate being programmed.
Programming Universal Home
Remote —Rolling Code
For questions or help programming
the Universal Home Remote
System, call 1-866-572-2728 or
go to www.learcar2u.com.
Most garage door openers sold
after 1996 are Rolling Code units.
Programming a garage door opener
involves time-sensitive actions, so
read the entire procedure before
starting. Otherwise, the device will
time out and the procedure will have
to be repeated.
To program up to three devices:
1. Press START or put the vehicle
in accessory mode. See Ignition
Positions on page 9‑20 for
additional information.
Programming can only occur
when the vehicle is running or in
accessory mode.

2. From inside the vehicle,press the two outside buttons
at the same time for one to
two seconds, and immediately
release them.
3. Locate in the garage,the garage door opener
receiver (motor-head unit). Locate the
“Learn”or“Smart”

30 seconds.
4. Immediately return to the vehicle. Press and hold the
Universal Home Remote button
that will be used to control the

garage door moves. The
indicator light blinks rapidly until
programming is complete. 6. Press and release the same
button again. The garage door
should move, confirming that
programming is successful and
complete.
To program another Rolling Code
device such as an additional garage
door opener, a security device,
or home automation device, repeat
Steps 1 through 6, choosing a
different function button in Step 4
than what was used for the garage
door opener.
If these instructions do not work,
the garage door opener is probably
a Fixed Code unit. Follow the

7-10 Infotainment System
XM Locked:The XM receiver in
the vehicle may have previously
been in another vehicle. For security
purposes, XM receivers cannot be
swapped between vehicles. If this
message is received after having
the vehicle serviced, check with
your dealer.
Radio ID: If tuned to channel 0,
this message will alternate with the
XM Radio eight‐digit radio ID label.
This label is needed to activate the
service.
Unknown: If this message is
received when tuned to channel 0,
there may be a receiver fault.
Consult with your dealer.
Chk XMRcvr: If this message does
not clear within a short period of
time, the receiver may have a fault.
Consult with your dealer.Radio Reception
Frequency interference and static
can occur during normal radio
reception if items such as cell phone
chargers, vehicle convenience
accessories, and external electronic
devices are plugged into the
accessory power outlet. If there is
interference or static, unplug the
item from the accessory power
outlet.
AM
The range for most AM stations is
greater than for FM, especially at
night. The longer range can cause
station frequencies to interfere
with each other. For better radio
reception, most AM radio stations
boost the power levels during the
day, and then reduce these levels
during the night. Static can also
occur when things like storms and
power lines interfere with radio
reception. When this happens, try
reducing the treble on the radio.
FM Stereo
FM signals only reach about
16 to 65 km (10 to 40 mi). Although
the radio has a built-in electronic
circuit that automatically works to
reduce interference, some static
can occur, especially around tall
buildings or hills, causing the sound
to fade in and out.
XM™ Satellite Radio Service
XM Satellite Radio Service gives
digital radio reception from coast to
coast in the 48 contiguous United
States, and in Canada. Just as
with FM, tall buildings or hills can
interfere with satellite radio signals,
causing the sound to fade in and
out. In addition, traveling or standing
under heavy foliage, bridges,
garages, or tunnels may cause loss
of the XM signal for a period of time.
Cellular Phone Usage
Cellular phone usage may cause
interference with the vehicle's
radio. This interference may occur

9-18 Driving and Operating
If you put things inside your
vehicle—like suitcases,
tools, packages or anything
else —they will go as fast as
the vehicle goes. If you have to
stop or turn quickly, or if there is
a crash, they will keep going.
{WARNING
Things you put inside your
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
.Put things in the rear area
of your vehicle. Try to
spread the weight evenly.
(Continued)
WARNING (Continued)
.Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
.Do not leave an
unsecured child restraint
in your vehicle.
.When you carry something
inside the vehicle, secure
it whenever you can.
Starting and
Operating
New Vehicle Break-In
Follow these recommended
guidelines during the first 2414 km
(1500 mi) of driving this vehicle.
Parts have a break-in period and
performance will be better in the
long run.
For the first 322 km (200 mi):
.To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first 322 km
(200 mi).
.New brake linings also need a
break- in period. Avoid making
hard stops during the first
322 km (200 mi). This is
recommended every time
brake linings are replaced.

helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Notice: If the air cleaner/filter is
off, dirt can easily get into the

4. With the coolant surge tankpressure cap off, start the
engine and let it run until the
upper radiator hose can be felt
getting hot. Any time during this
procedure, watch out for the
engine cooling fan.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper mixture to the coolant surge
tank until the level stabilizes at
the FULL COLD mark on the
coolant surge tank.
5. Replace the pressure cap. Be sure the pressure cap is
hand-tight and fully seated.
Check the level in the surge tank
when the system has cooled
down. If the coolant is not at
the proper level, repeat Steps 1
through 4, then reinstall the
pressure cap. If the coolant is
not at the proper level when the
system cools down again, see
the dealer.
Notice: If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is an engine coolant
temperature gauge on the
instrument panel cluster.
See Engine Coolant Temperature
Gauge on page 5‑16. The vehicle
may also display a COOLANT
OVER TEMPERATURE
message on the Driver Information
Center (DIC). See Engine Cooling
System Messages on page 5‑39
for more information.
If the decision is made not to lift the
hood but to get service help right
away. See Roadside Assistance
Program (U.S. and Canada) on
page 13‑8 orRoadside Assistance
Program (Mexico) on page 13‑10.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
