Do not use the Universal Home
Remote 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
Universal Home Remote. Because
of the steps involved, it may be
helpful to have another person
available to assist you with
programming the Universal Home
Remote.
Keep the original hand-held
transmitter for use in other vehicles
as well as for future Universal Home
Remote programming. It is also
recommended that upon the sale of
the vehicle, the programmed
Universal Home Remote buttons
should be erased for security
purposes. See“Erasing Universal
Home Remote Buttons” later in this
section. When programming a garage door,
park outside of the garage. Park
directly in line with and facing the
garage door opener motor-head or
gate motor-head. Be sure that
people and objects are clear of the
garage door or gate that is being
programmed.
It is recommended that a new
battery be installed in your
hand-held transmitter for quicker
and more accurate transmission of
the radio-frequency signal.
Programming the Universal
Home Remote System
For questions or help programming
the Universal Home Remote
System, call 1‐800‐355‐3515 or go
to www.homelink.com.
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. From inside the vehicle, press
and hold down the two outside
buttons at the same time,
releasing only when the
Universal Home Remote
indicator light begins to flash,
after 20 seconds. This step will
erase the factory settings or all
previously programmed buttons.
Do not hold down the buttons for
longer than 30 seconds and do
not repeat this step to program
the remaining two Universal
Home Remote buttons.

GVWR includes the weight of
the vehicle, all occupants, fuel,
and cargo. Never exceed the
GVWR for the vehicle, or the
Gross Axle Weight Rating
(GAWR) for either the front or
rear axle.
If the vehicle is carrying a heavy
load, it should be spread out.
See“Steps for Determining
Correct Load Limit” earlier in this
section.
{WARNING
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
If you do, parts on the vehicle
can break, and it can change
the way the vehicle handles.
(Continued)
WARNING (Continued)
These could cause you to lose
control and crash. Also,
overloading can shorten the
life of the vehicle.
{WARNING
Things you put inside the
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
.Put things in the cargo
area of the vehicle. In the
cargo area, put them as
far forward as you can. 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 the vehicle.
.When you carry something
inside the vehicle, secure
it whenever you can.
.Do not leave a seat folded
down unless you need to.

Driving and Operating 9-53
Pulling A Trailer
Here are some important points:
.There are many laws, including
speed limit restrictions that apply
to trailering. Check for legal
requirements with state or
provincial police.
.Do not tow a trailer at all during
the first 1 600 km (1,000 miles)
the new vehicle is driven. The
engine, axle, or other parts could
be damaged.
.During the first 800 km
(500 miles) that a trailer is
towed, do not drive over 80 km/h
(50 mph) and do not make starts
at full throttle. This reduces wear
on the vehicle.
.Vehicles with automatic
transmissions can tow in
D (Drive) but M (Manual Mode)
is recommended. SeeManual
Mode
on page 9‑28for more
information. Use a lower gear if
the transmission shifts too often. For vehicles with a manual
transmission, it is better not to
use the highest gear.
.Use the cruise control when
towing.
.Obey speed limit restrictions. Do
not drive faster than the
maximum posted speed for
trailers, or no more than 90 km/h
(55 mph), to reduce wear on the
vehicle.
Driving with a Trailer
Towing a trailer requires experience.
Get familiar with handling and
braking with the added trailer
weight. The vehicle is now longer
and not as responsive as the
vehicle is by itself.
Check all trailer hitch parts and
attachments, safety chains,
electrical connectors, lamps, tires,
and mirror adjustments. If the trailer
has electric brakes, start the vehicle
and trailer moving and then apply
the trailer brake controller by hand
to be sure the brakes are working.During the trip, check regularly to be
sure that the load is secure, and the
lamps and trailer brakes are working
properly.
Towing with a Stability Control
System
When towing, the sound of the
stability control system might be
heard. The system is reacting to the
vehicle movement caused by the
trailer, which mainly occurs during
cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid situations
that require heavy braking and
sudden turns.

2. Then keep turning the pressurecap slowly and remove it.3. Fill the coolant surge tank withthe proper mixture, to slightly
above the FROID/FULL COLD
line on the side of the coolant
surge tank.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until you
can feel the upper radiator hose
getting hot. The upper radiator
hose is the top hose coming out
of the radiator, on the passenger
side of the vehicle. Watch out for
the engine cooling fans. 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 reaches the
FROID/FULL COLD line on the
side of the coolant surge tank.
5. Then replace the pressure cap. Be sure the pressure cap is
hand-tight and fully seated.
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.
Recheck the coolant level in the
bottle next time you use your
vehicle to ensure the system is full
when cold.

4. Then replace the pressure cap.Be sure the pressure cap is
hand-tight and fully seated.
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.
If the coolant is not at the proper
level when the system cools down
again, see your dealer.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There are two engine hot messages
that may be displayed in the Driver
Information Center (DIC). See
Engine Cooling System Messages
on page 5‑35for more information.
You may decide not to lift the hood
when one of these warnings appear,
but get service help right away. See
Roadside Service on page 13‑7. If you do decide to lift the hood,
make sure the vehicle is parked on
a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fan(s)
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Notice:
Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice: If the engine catches fire
because of being driven with no
coolant, your vehicle can be
badly damaged. The costly
repairs would not be covered by
the vehicle warranty.
If Steam Is Coming from the
Engine Compartment
{WARNING
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when your
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop your
engine if it overheats, and get out
of the vehicle until the engine
is cool.

4. Put the vehicle in P (Park) for anautomatic transmission or in
1 (First) for a manual
transmission.
5. Securely attach the vehicle being towed to the dolly.
6. Clamp the steering wheel in a straight-ahead position with a
clamping device designed for
towing.
7. Turn the ignition to LOCK/OFF.Dolly Towing (All-Wheel-Drive
Vehicles)
Notice: Towing an all-wheel-drive
vehicle with all four wheels on the
ground, or even with only two of
its wheels on the ground, will
damage drivetrain components.
Do not tow an all-wheel-drive
vehicle with any of its wheels on
the ground.
All-wheel-drive vehicles can only be
towed with all four wheels on a
trailer.
