Jeep Grand Cherokee 2020 Owner's Manual page 303

WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
7. Remove the lug nuts and wheel.
8. Position the spare wheel/tire on the vehicle
and install the lug nuts with the
cone-shaped end toward the wheel. Lightly
tighten the nuts.
CAUTION!
Be sure to mount the spare tire with the valve
stem facing outward. The vehicle could be
damaged if the inflatable spare tire is
mounted incorrectly.
Mounting Spare Tire
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the wheel nuts fully until
the vehicle has been lowered. Failure to
follow this warning may result in serious
injury.
9. Lower the vehicle by turning the jack screw
counterclockwise, and remove the jack and
wheel blocks.
IN CASE OF EMERGENCY
10. Finish tightening the lug nuts. Push down on
the wrench while at the end of the handle
for increased leverage. Tighten the lug nuts
in a star pattern until each nut has been
tightened twice. For correct lug nut torque,
refer to "Wheel And Tire Torque Specifi-
cations" in "Technical Specifications" for
further information. If in doubt about the
correct tightness, have them checked with a
torque wrench by an authorized dealer or at
a service station.
Tighten Lug Nuts
11. Lower the jack to the fully closed position
and return it and the tools to the proper
positions in the foam tray.
