Jeep 2012 Grand Cherokee SRT - User Guide - Manual (Page 109)

Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shaped end of the nut
toward the wheel. Lightly tighten the lug nuts.
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 110 ft/lbs (150 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.
CAUTION!
• Do not attempt to raise the vehicle by jacking on locations other
than those indicated in the Jacking Instructions for this vehicle.
• Be sure to mount the spare tire with the valve stem facing outward.
The vehicle could be damaged if the spare tire is mounted
incorrectly.
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 the danger of
being hit when operating the jack or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip
off the jack and fall on you. You could be crushed. Never put any
part of your body under a vehicle that is on a jack. If you need to
get under a raised vehicle, take it to a service center where it can be
raised on a lift.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used as a tool for changing tires only. The
jack should not be used to lift the vehicle for service purposes. The
vehicle should be jacked on a firm level surface only. Avoid ice or
slippery areas.
• Always park on a firm, level surface as far from the edge of the
roadway as possible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to be raised.
• Set the parking brake firmly and set an automatic transmission in
PARK.
