Jeep Grand Cherokee 2020 Owner's Manual page 267

WARNING!
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, suspension,
chassis structure or tires.
Safety chains must always be used

between your vehicle and trailer. Always
connect the chains to the hook retainers of
the vehicle hitch. Cross the chains under
the trailer tongue and allow enough slack
for turning corners.
WARNING! (Continued)
Vehicles with trailers should not be parked

on a grade. When parking, apply the
parking brake on the tow vehicle. Put the
tow vehicle transmission in PARK. For
four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL. Always,
block or "chock" the trailer wheels.
GCWR must not be exceeded.

Total weight must be distributed between

the tow vehicle and the trailer such that the
following four ratings are not exceeded:
GVWR

GTW

GAWR

Tongue weight rating for the trailer

hitch utilized.

STARTING AND OPERATING
Towing Requirements — Tires
Do not attempt to tow a trailer while using a

compact spare tire.
Do not drive more than 50 mph (80 km/h)

when towing while using a full size spare tire.
Proper tire inflation pressures are essential

to the safe and satisfactory operation of your
vehicle. Refer to "Tires" in "Servicing And
Maintenance" for proper tire inflation proce-
dures.
Check the trailer tires for proper tire inflation

pressures before trailer usage.
Check for signs of tire wear or visible tire

damage before towing a trailer. Refer to
"Tires" in "Servicing And Maintenance" for
the proper inspection procedure.
When replacing tires, refer to "Tires" in

"Servicing And Maintenance" for the proper
tire replacement procedures. Replacing tires
with a higher load carrying capacity will not
increase the vehicle's GVWR and GAWR
limits.
