Push the lever down to completely
engage into the side rail holes. If the
lever is not tight, then the cross rail
is not engaged in a side rail hole.
Slide the cross rails back and forth
until the lock pins engage in the
holes and a click is heard as the
pins align and the cross rail locks.Try sliding the cross rails forward
and backward to ensure that they
are correctly secured and that the
levers stay tight to the cross rails.
Do not stand on the plastic lower
body panels when loading cargo on
the roof rack.
When the roof rack is not in use,
lock one cross rail at the furthest
forward position and lock the other
cross rail at the furthest rearward
position to reduce wind noise.

Universal Remote System
Programming
If the vehicle has this feature, you
will see these buttons with one
indicator light next to them in the
overhead console.
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 the Universal Remote
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
Universal Remote system. Because
of the steps involved, it may be
helpful to have another person
available to assist with programming
the Universal Remote system.
Keep the original hand-held
transmitter for use in other vehicles
as well as for future Universal
Remote system programming. It is
also recommended that upon the
sale of the vehicle, the programmed
Universal Remote system buttons
be erased for security purposes.
See
“Erasing Universal Remote
System Buttons” later in this
section.

Driving and Operating 9-7
Loading the Vehicle for
Off-Road Driving
{WARNING
.Unsecured cargo on the load
floor can be tossed about
when driving over rough
terrain. You or your
passengers can be struck by
flying objects. Secure the
cargo properly.
.Keep cargo in the cargo area
as far forward and as low as
possible. The heaviest things
should be on the floor,
forward of the rear axle.
.Heavy loads on the roof raise
the vehicle's center of gravity,
making it more likely to roll
over. You can be seriously or
fatally injured if the vehicle
rolls over. Put heavy loads
inside the cargo area, not on
the roof.For more information about loading
the vehicle, see
Vehicle Load Limits
on page 9‑14.
Environmental Concerns
.Always use established trails,
roads, and areas that have been
set aside for public off-road
recreational driving and obey all
posted regulations.
.Do not damage shrubs, flowers,
trees, or grasses or disturb
wildlife.
.Do not park over things that
burn. See Parking over Things
That Burn on page 9‑25.
Driving on Hills
Driving safely on hills requires good
judgment and an understanding of
what the vehicle can and cannot do.
{WARNING
Many hills are simply too steep
for any vehicle. Driving up hills
can cause the vehicle to stall.
Driving down hills can cause loss
of control. Driving across hills can
cause a rollover. You could be
injured or killed. Do not drive on
steep hills.
Before driving on a hill, assess the
steepness, traction, and
obstructions. If the terrain ahead
cannot be seen, get out of the
vehicle and walk the hill before
driving further.
When driving on hills:
.Use a low gear and keep a firm
grip on the steering wheel.
.Maintain a slow speed.
.When possible, drive straight up
or down the hill.
.Slow down when approaching
the top of the hill.

9-18 Driving and Operating
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).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
shorten the life of the vehicle.
Your warranty does not cover
parts or components that fail
because of overloading. The label will help you decide
how much cargo and installed
equipment your vehicle can
carry.
Using heavier suspension
components to get added
durability might not change your
weight ratings. Ask your dealer
to help you load your vehicle the
right way.
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 inside the vehicle can
strike and injure people in a
sudden stop or turn, or in a
crash.
(Continued)
WARNING (CONTINUED)
.Put things in the cargo
area of the vehicle. In the
cargo area, put them as
far forward as possible.
Try to spread the weight
evenly.
.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.
.Secure loose items in the
vehicle.
.Do not leave a seat folded
down unless needed.

9-54 Driving and Operating
Towing a trailer requires a certain
amount of experience. The
combination you are driving is
longer and not as responsive as the
vehicle itself. Get acquainted with
the handling and braking of the rig
before setting out for the open road.
Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires and mirrors. If the trailer has
electric brakes, start the
combination moving and then apply
the trailer brake controller by hand
to be sure the brakes work.
During the trip, check occasionally
to be sure that the load is secure
and the lamps and any trailer
brakes still work.
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 thetrailer, 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.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
farther beyond the passed vehicle
before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. To move the
trailer to the left, move your hand to
the left. To move the trailer to the
right, move your hand to the right.
Always back up slowly and,
if possible, have someone
guide you.
Making Turns
Notice:
Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal so the
trailer will not strike soft shoulders,
curbs, road signs, trees or other
objects. Use the turn signal well in
advance and avoid jerky or sudden
maneuvers.
Turn Signals When Towing a
Trailer
The turn signal indicators on the
instrument panel flash whenever
signaling a turn or lane change.
Properly hooked up, the trailer
lamps also flash, telling other
drivers the vehicle is turning,
changing lanes or stopping.
