Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h) when towing while using a full size spare tire.
Proper tire inflation pressures are essential
to the safe and satisfactory operation of your
vehicle.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
When replacing tires with a higher load
carrying capacity they will not increase the
vehicle's GVWR and GAWR limits.
For further information Ú page 234.
WARNING!
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured,
dynamic load shifts can occur that may be
difficult for the driver to control. You could
lose control of your vehicle and have a colli -
sion.
When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over -
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, steering, suspension,
chassis structure or tires.
Safety chains must always be used
between your vehicle and trailer. Always
connect the chains to the hook retainers of
the vehicle hitch. Cross the chains under
the trailer tongue and allow enough slack
for turning corners.
Vehicles with trailers should not be parked
on a grade. When parking, apply the
parking brake on the tow vehicle. Put the
tow vehicle transmission in PARK. For
four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL. Always,
block or "chock" the trailer wheels.
GCWR must not be exceeded.
Total weight must be distributed between
the tow vehicle and the trailer such that the
following four ratings are not exceeded :
GVWR
GTW
GAWR
Tongue weight rating for the trailer
hitch utilized.

HSA will work in REVERSE and all forward gears
when the activation criteria have been met. The
system will not activate if the vehicle is placed
in NEUTRAL or PARK.
Traction Control System (TCS)
TCS monitors the amount of wheel spin of each
of the driven wheels. If wheel spin is detected,
brake pressure is applied to the slipping
wheel(s) and engine power is reduced to
provide enhanced acceleration and stability. A
feature of the TCS system, Brake Limited
Differential (BLD), functions similarly to a
limited slip differential and controls the wheel
spin across a driven axle. If one wheel on a
driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will allow more engine torque to be
applied to the wheel that is not spinning. This
feature remains active even if TCS and ESC are
in the “Partial Off” mode Ú
page 146.
Trailer Sway Control (TSC) — If Equipped
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
The system may reduce engine power and apply
the brake of the appropriate wheel(s) to
counteract the sway of the trailer.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda -
tions Ú page 77.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced and you may feel the
brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial
Off” mode.
AUXILIARY DRIVING SYSTEMS
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure based
on the vehicle recommended cold placard
pressure.
The tire pressure will vary with temperature by
about 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature
decreases, the tire pressure will decrease. Tire
pressure should always be set based on cold
inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than
1 mile (1.6 km) after a three hour period. The
cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the
WARNING!
There may be situations on minor hills with a
loaded vehicle, or while pulling a trailer, when
the system will not activate and slight rolling
may occur. This could cause a collision with
another vehicle or object. Always remember
the driver is responsible for braking the
vehicle.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer
sway.

Summary Of Recommendations For Restraining Children In Vehicles
Infant And Child Restraints
Safety experts recommend that children ride
rear-facing in the vehicle until they are two years
old or until they reach either the height or
weight limit of their rear-facing child restraint.
Two types of child restraints can be used
rear-facing: infant carriers and convertible child
seats. The infant carrier is only used rear-facing in the
vehicle. It is recommended for children from
birth until they reach the weight or height limit of
the infant carrier. Convertible child seats can be
used either rear-facing or forward-facing in the
vehicle. Convertible child seats often have a
higher weight limit in the rear-facing direction
than infant carriers do, so they can be used
rear-facing by children who have outgrown their infant carrier but are still less than at least two
years old. Children should remain rear-facing
until they reach the highest weight or height
allowed by their convertible child seat.
Child Size, Height, Weight Or Age Recommended Type Of Child Restraint
Infants and Toddlers
Children who are two years old or younger and
who have not reached the height or weight limits
of their child restraint Either an Infant Carrier or a Convertible Child
Restraint, facing rearward in a rear seat of the
vehicle
Small Children Children who are at least two years old or who
have outgrown the height or weight limit of their
rear-facing child restraint Forward-Facing Child Restraint with a five-point
Harness, facing forward in a rear seat of the
vehicle
Larger Children Children who have outgrown their forward-facing
child restraint, but are too small to properly fit
the vehicle’s seat belt Belt Positioning Booster Seat and the vehicle
seat belt, seated in a rear seat of the vehicle
Children Too Large for Child Restraints Children 12 years old or younger, who have
outgrown the height or weight limit of their
booster seat Vehicle Seat Belt, seated in a rear seat of the
vehicle

Older Children And Child Restraints
Children who are two years old or who have
outgrown their rear-facing convertible child seat
can ride forward-facing in the vehicle.
Forward-facing child seats and convertible child
seats used in the forward-facing direction are
for children who are over two years old or who
have outgrown the rear-facing weight or height
limit of their rear-facing convertible child seat. Children should remain in a forward-facing child
seat with a harness for as long as possible, up
to the highest weight or height allowed by the
child seat.
All children whose weight or height is above the
forward-facing limit for the child seat should use
a belt-positioning booster seat until the
vehicle’s seat belts fit properly. If the child
cannot sit with knees bent over the vehicle’s
seat cushion while the child’s back is against
the seatback, they should use a belt-positioning
booster seat. The child and belt-positioning
booster seat are held in the vehicle by the seat
belt.
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious
injury to a child 12 years or younger,
including a child in a rear-facing child
restraint.
Never install a rear-facing child restraint in
the front seat of a vehicle. Only use a
rear-facing child restraint in the rear seat. If
the vehicle does not have a rear seat, do
not transport a rear-facing child restraint in
that vehicle.
WARNING!
Improper installation can lead to failure of
an infant or child restraint. It could come
loose in a collision. The child could be badly
injured or killed. Follow the child restraint
manufacturer’s directions exactly when
installing an infant or child restraint.
After a child restraint is installed in the
vehicle, do not move the vehicle seat
forward or rearward because it can loosen
the child restraint attachments. Remove
the child restraint before adjusting the
vehicle seat position. When the vehicle seat
has been adjusted, reinstall the child
restraint.
When your child restraint is not in use,
secure it in the vehicle with the seat belt or
LATCH anchorages, or remove it from the
vehicle. Do not leave it loose in the vehicle.
In a sudden stop or accident, it could strike
the occupants or seatbacks and cause
serious personal injury.

Frequently Asked Questions About Installing Child Restraints With LATCH
What is the weight limit (child’s weight + weight
of the child restraint) for using the LATCH
anchorage system to attach the child restraint? 65 lbs (29.5 kg)Use the LATCH anchorage system until the
combined weight of the child and the child
restraint is 65 lbs (29.5 kg). Use the seat belt
and tether anchor instead of the LATCH system
once the combined weight is more than 65 lbs
(29.5 kg).
Can the LATCH anchorages and the seat belt be
used together to attach a rear-facing or
forward-facing child restraint? NoDo not use the seat belt when you use the
LATCH anchorage system to attach a rear-facing
or forward-facing child restraint.
Booster seats may be attached to the LATCH
anchorages if allowed by the booster seat
manufacturer. See your booster seat owner’s
manual for more information.
Can a child seat be installed in the center
position using the inner LATCH lower
anchorages from the outboard seating
positions? No
Use the seat belt and tether anchor to install a
child seat in the center seating position.
Can two child restraints be attached using a
common lower LATCH anchorage? NoNever “share” a LATCH anchorage with two or
more child restraints. If the center position does
not have dedicated LATCH lower anchorages,
use the seat belt to install a child seat in the
center position next to a child seat using the
LATCH anchorages in an outboard position.

Installing A Child Restraint With A Switchable
Automatic Locking Retractor (ALR):
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the lap
belt portion of a lap/shoulder belt.
1. Place the child seat in the center of the seating position. If the second row seat can
be reclined, you may recline the seat and/
or raise the head restraint (if adjustable) to
get a better fit. If the rear seat can be
moved forward and rearward in the vehicle, you may wish to move it to its
rear-most position to make room for the
child seat. You may also move the front
seat forward to allow more room for the
child seat.

2. Pull enough of the seat belt webbing from the retractor to pass it through the belt path
of the child restraint. Do not twist the belt
webbing in the belt path.
3. Slide the latch plate into the buckle until you hear a “click.”
Frequently Asked Questions About Installing Child Restraints With Seat Belts
What is the weight limit (child’s weight + weight
of the child restraint) for using the Tether Anchor
with the seat belt to attach a forward facing
child restraint? Weight limit of the Child RestraintAlways use the tether anchor when using the
seat belt to install a forward facing child
restraint, up to the recommended weight limit of
the child restraint.
Can the rear-facing child restraint touch the
back of the front passenger seat? YesContact between the front passenger seat and
the child restraint is allowed, if the child
restraint manufacturer also allows contact.
Can the rear head restraints be removed? YesThe 2nd row head restraints can be removed in
every seating position if they interfere with the
installation of the child restraint Ú
page 21.
Can the buckle stalk be twisted to tighten the
seat belt against the belt path of the child
restraint? No
Do not twist the buckle stalk in a seating
position with an ALR retractor.
