Towing Requirements - Jeep Grand Cherokee 2018 Manual

Towing Requirements

To promote proper break-in of your new vehicle
drivetrain components, the following guidelines
are recommended.
CAUTION!
• Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts
could be damaged.
• Then, during the first 500 miles (805 km)
that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.
Perform the maintenance listed in the "Sched-
uled Servicing". Refer to "Scheduled Servicing"
in "Servicing And Maintenance" for the proper
maintenance intervals. When towing a trailer,
never exceed the GAWR or GCWR ratings.
WARNING!
Improper towing can lead to a collision. Fol-
low these guidelines to make your trailer
towing as safe as possible:
• 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
collision.
• 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, suspen-
sion, chassis structure or tires.
• Safety chains must always be used be-
tween your vehicle and trailer. Always con-
nect 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 park-
ing brake on the tow vehicle. Put the tow
vehicle transmission in PARK. For four-
wheel drive vehicles, make sure the trans-
fer case is not in NEUTRAL. Always, block
or "chock" the trailer wheels.
• GCWR must not be exceeded.

tween the tow vehicle and the trailer

utilized.

vehicle. Refer to "Tires" in "Servicing And
Maintenance"
procedures.
• Check the trailer tires for proper tire inflation
pressures before trailer usage.
