10–15% (conventional trailer) or king pin weight of 15–25% (fifth wheel
trailer), and driver only (68 kg [150 lbs]).Consult your dealership (or
the RV and Trailer Towing Guide provided by your dealership) for
more detailed information.
Tongue Load or Fifth Wheel King Pin Weight–refers to the amount
of the weight that a trailer pushes down on a trailer hitch.
Examples:For a 2268 kg (5000 lbs.) conventional trailer, multiply 5000
by 0.10 and 0.15 to obtain a proper tongue load range of 227 to 340 kg
(500 to 750 lbs.). For an 5216 kg (11,500 lbs.) fifth wheel trailer,
multiply by 0.15 and 0.25 to obtain a proper king pin load range of 782
to 1304 kg (1,725 to 2,875 lbs.)
Do not exceed the GVWR or the GAWR specified on the
certification label.
Do not use replacement tires with lower load carrying capacities
than the originals because they may lower the vehicle’s GVWR
and GAWR limitations. Replacement tires with a higher limit than the
originals do not increase the GVWR and GAWR limitations.
Exceeding any vehicle weight rating limitation could result in
serious damage to the vehicle and/or personal injury.
TRAILER TOWING
Your vehicle is capable either of towing Class I trailers or up to Class II
trailers when equipped with the optional trailer tow package.
If your vehicle does not have the optional trailer tow package your
vehicle is partially prepped for trailer tow lamp wiring but you will also
need to install electrical kit 3F2Z-15A416-A. This kit contains fuses and
relays to isolate the vehicle lighting circuitry from the trailer lighting and
an adapter wiring harness containing the standard 4-pin trailer plug.
Refer to theTrailer lampssection in this chapter for additional
information.Do not tow above 907 kg (2000 lbs) without the
manufacturer-installed trailer tow package.
If your vehicle has the optional trailer tow package it comes with heavy
duty cooling fans, auxiliary transmission fluid cooler, an auxiliary engine
oil cooler, heavy duty battery, trailer tow wiring (including fuses and
relays to isolate the vehicle lighting circuitry from the trailer lighting)

FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.
