Jump-Starting Procedures - Jeep Wrangler 2013 Owner's Manual

WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in personal injury.
3. Lower the vehicle to the ground by turning the jack
handle counterclockwise.
4. 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. The correct tightness of each lug
nut is 95 ft lbs (130 N·m). If in doubt about the correct
tightness, have them checked with a torque wrench by
your authorized dealer or service station.
5. After 25 miles (40 km) check the lug nut torque with a
torque wrench to ensure that all lug nuts are properly
seated against the wheel.
