Note:Certain states require electric trailer brakes for trailers over a
specified weight. Be sure to check state regulations for this specified
weight. The maximum trailer weights listed may be limited to this
specified weight, as the vehicle’s electrical system may not include the
wiring connector needed to activate electric trailer brakes.
Your vehicle may tow a Class I, II or III trailer provided the maximum
trailer weight is less than or equal to the maximum trailer weight listed
for your vehicle configuration on the following chart.

ESSENTIAL TOWING CHECKS
Follow these guidelines to ensure safe towing:
•Do not tow a trailer until your vehicle has been driven at least
1000 miles (1600 kilometers).
•Consult your local motor vehicle laws for towing a trailer.
•Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
•Service your vehicle more frequently if you tow a trailer. Refer to your
scheduled maintenance information.
•If you use a rental trailer, follow the instructions the rental agency
gives you.
For load specification terms found on the tire label and Safety
Compliance label and for instructions on calculating your vehicle’s load,
refer toLoad limitin theLoad Carryingchapter.
Remember to account for the trailer tongue weight as part of the vehicle
load when calculating the total vehicle weight.

Hitches
Do not use a hitch that either clamps onto the bumper or attaches to the
axle. Distribute the trailer load so 10–15% of the total trailer weight is on
the tongue.
Weight-Distributing Hitch
When hooking-up a trailer using a weight-distributing hitch, always use
the following procedure:
1. Park the loaded vehicle (without the trailer) on a level surface.
2. Measure the height to the top of the vehicle front wheel opening on
the fender, this is H1.
3. Securely attach the loaded trailer to the vehicle without the
weight-distributing bars connected.
4. Measure the height to the top of the vehicle front wheel opening on
the fender a second time, this is H2.
5. Install and adjust the tension in the weight-distributing bars so that
the height of the vehicle’s front wheel opening on the fender is
approximately halfway between H1 and H2.
6. Check that the trailer is level or slightly nose down. If not, adjust the
ball height accordingly and repeat Steps 1 through 6.
7. Lock bar tension adjuster in place.
8. Check that the trailer tongue is securely attached and locked to the
hitch.
9. Install safety chains, lighting, and trailer brake controls as required
by law or the trailer manufacturer.
WARNING:Do not adjust a weight-distributing hitch to any
position where the rear bumper of the vehicle is higher than it
was before attaching the trailer. Doing so will defeat the function of the
weight-distributing hitch, which may cause unpredictable handling, and
could result in serious personal injury.
Safety Chains
Note:Never attach safety chains to the bumper.
Always connect the safety chains to the hook retainers of the vehicle
hitch.
To connect the safety chains, cross them under the trailer tongue and
allow enough slack for turning tight corners. Do not allow the chains to
drag on the ground.
56Towing

Owners Guide gf, 1st Printing
USA(fus)
•Carry unnecessary weight (approximately 1 mpg [0.4 km/L] is lost for
every 400 lb [180 kg] of weight carried).
•Add particular accessories to your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski racks).
•Drive with the wheels out of alignment.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly. Never drive through water
that is higher than the bottom of
the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall.
Note:Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause internal
transmission damage.
Note:Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal. Wet
brakes do not stop the vehicle as quickly as dry brakes.

Note:A clear gel-like substance in the hydraulic brake master cylinder
reservoir may appear on some vehicles. This substance is a silicone base
lubricant used during assembly of the master cylinder. It will float on top
of the brake hydraulic fluid in the master cylinder. This condition is
normal and in no way affects the operation of the brake system. It does
not require any service.

Glossary of Tire Terminology
•Tire label:A label showing the OE (Original Equipment) tire sizes,
recommended inflation pressure and the maximum weight the vehicle
can carry.
•Tire Identification Number (TIN):A number on the sidewall of
each tire providing information about the tire brand and
manufacturing plant, tire size and date of manufacture. Also referred
to as DOT code.
•Inflation pressure:A measure of the amount of air in a tire.
•Standard load:A class of P-metric or Metric tires designed to carry a
maximum load at 35 psi [37 psi (2.5 bar) for Metric tires]. Increasing
the inflation pressure beyond this pressure will not increase the tire’s
load carrying capability.
•Extra load:A class of P-metric or Metric tires designed to carry a
heavier maximum load at 41 psi [43 psi (2.9 bar) for Metric tires].
Increasing the inflation pressure beyond this pressure will not increase
the tire’s load carrying capability.
•kPa:Kilopascal, a metric unit of air pressure.
•PSI:Pounds per square inch, a standard unit of air pressure.
•Cold inflation pressure:The tire pressure when the vehicle has
been stationary and out of direct sunlight for an hour or more and
prior to the vehicle being driven for 1 mile (1.6 km).
•Recommended inflation pressure:The cold inflation pressure found
on the Safety Compliance Certification Label. See the completed
vehicle’s owner’s guide for the location of the Safety Compliance
Certification Label.
•Bead area of the tire:Area of the tire next to the rim.
•Sidewall of the tire:Area between the bead area and the tread.
•Tread area of the tire:Area of the perimeter of the tire that
contacts the road when mounted on the vehicle.
•Rim:The metal support (wheel) for a tire or a tire and tube assembly
upon which the tire beads are seated.

Information on “P” Type Tires
P215/65R15 95H is an example of a
tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.)
A.P:Indicates a tire, designated by
the Tire and Rim Association
(T&RA), that may be used for
service on cars, SUVs, minivans and
light trucks.
Note:If your tire size does not
begin with a letter this may mean it
is designated by either ETRTO
(European Tire and Rim Technical
Organization) or JATMA (Japan Tire Manufacturing Association).
B.215:Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
C.65:Indicates the aspect ratio which gives the tire’s ratio of height to
width.
D.R:Indicates a “radial” type tire.
E.15:Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
F.95:Indicates the tire’s load index. It is an index that relates to how
much weight a tire can carry. You may find this information in your
owner’s guide. If not, contact a local tire dealer.
Note:You may not find this information on all tires because it is not
required by federal law.

When driving with the full-size dissimilar spare tire and wheel assembly,
additional caution should be given to:
•Towing a trailer
•Driving vehicles equipped with a camper body
•Driving vehicles with a load on the cargo rack
Drive cautiously when using a full-size dissimilar spare tire and wheel,
and seek service as soon as possible.
Tire Change Procedure
WARNING:When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the transmission selector lever is in
positionP.
WARNING:To help prevent the vehicle from moving when you
change a tire, be sure to place the transmission selector lever in
positionP, set the parking brake and block (in both directions) the
wheel that is diagonally opposite (other side and end of the vehicle) to
the tire being changed.
WARNING:Never get underneath a vehicle that is supported
only by a jack. If the vehicle slips off the jack, you or someone
else could be seriously injured.
WARNING:Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack or changing the
wheel.
WARNING:Always use the jack provided as original equipment
with your vehicle. If using a jack other than the one provided as
original equipment with your vehicle, make sure the jack capacity is
adequate for the vehicle weight, including any vehicle cargo or
modifications.
