TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or the
GAWR specified on the certification
label. 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. Note:
Your vehicle may have electrical
items, such as fuses or relays, related
to towing. See Fuses (page 269). 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. 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 the
Load Carrying chapter. See Load Limit
(page 235).
You can also find information in the
RV
& Trailer Towing Guide available at your
authorized dealer, or online.
