Jeep 2013 Wrangler - Manual (Page 544)

Spare Tire Stowage
To remove the spare tire from the carrier, remove the tire
cover, if equipped, and remove the lug nuts with the lug
wrench turning them counterclockwise.
NOTE: If you have added aftermarket accessories to the
spare tire mounted carrier, it cannot exceed a gross weight
of 50 lbs (23 kg) including the weight of the spare tire.
Preparations For Jacking
1. Park on a firm, level surface. Avoid ice or slippery areas.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic, pull far enough off
the road to avoid being hit when operating the jack
or changing the wheel.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Shift the automatic transmission into PARK, or a
manual transmission into REVERSE.
5. Turn the ignition to LOCK.
Block both the front and rear of the
wheel diagonally opposite of the jack-
ing position. For example, if changing
the right front tire, block the left rear
wheel.
NOTE: Passengers should not remain in the vehicle
when the vehicle is being jacked.
