2013 JEEP WRANGLER spare tire

message is then followed by a graphic display, with
pressure values still shown. This indicates the pressure
values are still being received from the TPM Sensors but
they may not be located in the correct vehicle position.
However, the system still needs to be serviced as long as
theSERVICE TPM SYSTEM message exists.
NOTE:
•
If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS). In the event that
the matching full-size spare tire is swapped with a low
pressure road tire, the next ignition switch cycle will still
show the “Tire Pressure Monitoring Telltale Light” to be
ON, a chime to sound, a “LOW TIRE PRESSURE”
message to appear in the EVIC, and the graphic display
will still show the low tire pressure value “flashing.”
Driving the vehicle for up to 20 minutes above 15 mph (24 km/h) will turn OFF the “Tire Pressure Monitoring
Telltale Light” as long as none of road tires are below the
low pressure warning threshold.
•
If your vehicle is not equipped with a matching
full-size spare wheel and tire assembly, it does not
have a tire pressure monitoring sensor in the spare tire.
The TPMS will not be able to monitor the tire pressure.
If you install the spare tire in place of a road tire that
has a pressure below the low-pressure warning limit,
upon the next ignition switch cycle, the “Tire Pressure
Monitoring Telltale Light” will remain ON, a chime
will sound, and the EVIC will still display a “flashing”
pressure value in the graphic display. After driving the
vehicle for up to 20 minutes above 15 mph (24 km/h),
the “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds and then remain on solid. In
addition, the EVIC will display a “SERVICE TPM
SYSTEM message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value.

STARTING AND OPERATING 511

For each subsequent ignition switch cycle, a chime will
sound, the “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds and then remain on
solid, and the EVIC will display aSERVICE TPM
SYSTEM message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value.
Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the spare tire, the
TPMS will update automatically.
In addition, the “Tire Pressure Monitoring Telltale Light”
will turn OFF and the graphic in the EVIC will display a
new pressure value instead of dashes (- -), as long as no
tire pressure is below the low-pressure warning limit in
any of the four active road tires. The vehicle may need to
be driven for up to 20 minutes above 15 mph (24 km/h)
in order for the TPMS to receive this information.General Information

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 69 lbs (31.3 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.

WARNING!(Continued)
•Do not let anyone sit in the vehicle when it is on a
jack.
• Do not get under the vehicle when it 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.
• Only use the jack in the positions indicated and for
lifting this vehicle during a tire change.
• If working on or near a roadway, be extremely
careful of motor traffic.
• To assure that spare tires, flat or inflated, are
securely stowed, spares must be stowed with the
valve stem facing out.
CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the Jacking
Instructions for this vehicle.
1. Remove the spare tire, jack and tools from the stored location.
2. Loosen (but do not remove) the wheel lug nuts by turning them to the left one turn while the wheel is
still on the ground.

WHAT TO DO IN EMERGENCIES 551

WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable and cause a collision. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
6. Remove the lug nuts and wheel.
7. Position the spare wheel/tire on the vehicle and install the lug nuts with the cone-shaped end toward the
wheel. Lightly tighten the lug nuts clockwise.
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.
Lug Nut Installation6
WHAT TO DO IN EMERGENCIES 553

8. Lower the vehicle by turning the jack screw to the left,and remove the jack.
9. Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alter-
nate nuts until each nut has been tightened twice. The
correct wheel nut tightness 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 at
a service station.
10. Remove the jack assembly and wheel blocks.
11. Secure the tire, jack, and tools in their proper loca- tions.WARNING!
A loose tire or jack thrown forward in a collision or
hard stop, could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shapedend of the nut toward the wheel. Lightly tighten the
lug nuts.
554 WHAT TO DO IN EMERGENCIES

Rear Tail, Stop, Turn Signal, And Backup Lamp
1. Remove the two inboard screws attaching the tail lighthousing to the body. DO NOT REMOVE THE
OUTER SCREWS AT ANY TIME.
2. Separate the housing from the body by pushing the lamp inboard while pulling the lamp away from the
body. 3. Rotate the appropriate socket 1/4 turn counterclock-
wise, then remove it from the housing.
4. Pull the bulb straight from the socket to replace.
Center High-Mounted Stop Lamp (CHMSL)
The stop lamp is mounted on a bracket that extends
upward from the tailgate behind the spare tire. If service
is needed, obtain the LED/Cover Assembly from your
local authorized dealer.
1. Remove the spare tire.
2. Remove the four screws holding the lens/cover in place on the spare tire carrier.
3. Disconnect the wire harness from the back of the LED cover.
