TOWING A TRAILER
WARNING: Towing trailers
beyond the maximum recommended
gross trailer weight exceeds the limit
of your vehicle and could result in
engine damage, transmission damage,
structural damage, loss of vehicle
control, vehicle rollover and personal
injury. WARNING:
Do not exceed the
GVWR or the GAWR specified on the
certification label.
Note: See
Recommended Towing
Weights (page 327).
Your vehicle may have electrical items,
such as fuses or relays, related to
towing.
See Fuses (page 360). Your vehicle's load capacity designation
is by weight, not by volume, so you
cannot necessarily use all available
space when loading a vehicle or trailer.
Towing a trailer places an extra load on
your vehicle's engine, transmission, axle,
brakes, tires and suspension. Inspect
these components periodically during,
and after, any towing operation.
Load Placement
To help minimize how trailer movement
affects your vehicle when driving:
•
Load the heaviest items closest to
the trailer floor.
• Load the heaviest items centered
between the left and right side trailer
tires. •
Load the heaviest items above the
trailer axles or just slightly forward
toward the trailer tongue. Do not
allow the final trailer tongue weight
to go above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the correct
rise or drop and load capacity. When
both the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly angled
down toward your vehicle, when
viewed from the side.
When driving with a trailer or payload, a
slight takeoff vibration or shudder may
be present due to the increased payload
weight. Additional information regarding
proper trailer loading and setting your
vehicle up for towing is located in
another chapter of this manual.
See
Load Limit (page 309).
You can also find information in the
RV
& Trailer Towing Guide available at your
authorized dealer, or online.
