spare wheel JEEP COMMANDER 2007 1.G Owners Manual

Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect for tread cuts or sidewall
cracks. Check wheel nuts for tightness and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of all exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
coolant, oil or other fluid leaks. Also, if gasoline fumes
are detected, the cause should be located and corrected
immediately.
70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

A tire pressure monitoring sensor is located in the spare
wheel if the vehicle is equipped with a matching full size
spare wheel and tire assembly. The matching full size spare
tire can be used in place of any of the four road tires.
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more of
the four active road tire pressures are low. The audible
chime will sound once every ignition cycle for each
condition that it detects. Should this occur, you should
stop as soon as possible, check the inflation pressure of
each tire on your vehicle, and inflate each tire to the
vehicle’s recommended cold tire pressure. The system
will automatically update and the “Tire Pressure Moni-
toring Light” will extinguish once the updated tire pres-
sures have been received. The vehicle may need to be
driven for up to 10 minutes above 15 mph (24 km/h) to
receive this information. A low spare tire will not cause
the “Tire Pressure Monitoring Telltale Light” to illumi-
nate or the chime to sound.The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 60 seconds, and an audible chime will
sound when a system fault is detected. The flash cycle
will repeat every ten minutes, without an audible chime,
until the fault condition no longer exists. If the ignition
key is cycled, this sequence will repeat, providing the
system fault still exists.
NOTE:If your vehicle is equipped with a matching full
size spare tire, 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 key cycle will still show the “Tire Pressure
Monitoring Telltale Light” to be ON, and a chime to
sound. Driving the vehicle for up to 10 minutes above 15
mph (24 km/h) will turn OFF the “Tire Pressure Moni-
toring Telltale Light” as long as the spare tire or any other
road tire(s) are not below the low pressure warning
threshold.

NOTE:If your vehicle is equipped with a non-matching
full size spare tire, it does not have a tire pressure
monitoring sensor. Therefore, it will not be monitored by
the Tire Pressure Monitor System (TPMS). In the event
that the non-matching full size spare tire is swapped with
a low pressure road tire, each ignition key cycle will still
show the “Tire Pressure Monitoring Telltale Light” to be
ON, and a chime to sound. After the original road tire has
been properly repaired and put back onto the vehicle in
place of the non-matching full size spare tire, the TPMS
will update automatically, and the “Tire Pressure Moni-
toring Telltale Light” will be OFF as long as none of the
road tires are below the low pressure warning threshold.
The vehicle may need to be driven for up to 10 minutes
above 15 mph (24 km/h) to receive this information.CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
After-market wheels can cause sensor damage. Do
not use tire sealant from a can, or balance beads if
your vehicle is equipped with a TPMS, as damage to
the sensors may result.
300 STARTING AND OPERATING

The Tire Pressure Monitor System (TPMS) consists of the
following components:
•Receiver Module
•4 Tire Pressure Monitoring Sensors
•3 Trigger Modules (mounted in three of the four wheel
wells)
•Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC)
•Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in the spare
wheel if the vehicle is equipped with a matching full size
spare wheel and tire assembly. The matching full size
spare tire can be used in place of any of the four road
tires.
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more of
the four active road tire pressures are low. The audible
chime will sound once every ignition cycle for each
condition that it detects. In addition, the Electronic
Vehicle Information Center (EVIC) will display one or
more Low Pressure messages (Left Front, Left Rear, Right
Front, Right Rear) for 3 seconds, and a graphic display of
the pressure value(s) with the low tire(s) flashing. Refer
to “Electronic Vehicle Information Center (EVIC)” in
Section 4 of this manual.
NOTE:If your vehicle is equipped with a matching full
size spare tire, a low matching full size spare tire will set
the “SPARE LOW PRESSURE” text message, but it will
not cause the “Tire Pressure Monitoring Telltale Light” to
illuminate or the chime to sound.
302 STARTING AND OPERATING

low pressure warning threshold. The EVIC will display a
“Spare Low Pressure” text message, and the graphic
display will show a new tire pressure value in place of
the flashing low tire pressure value.
NOTE:If your vehicle is equipped with a non-matching
full size spare tire, it does not have a tire pressure
monitoring sensor. Therefore, it will not be monitored by
the Tire Pressure Monitor System (TPMS). In the event
that the non-matching full size spare tire is swapped with
a low pressure road tire, every ignition key cycle will still
show the “Tire Pressure Monitoring Telltale Light” to be
ON, a chime to sound, a Low Pressure message to appear
in the EVIC, and the graphic display will still show the
low tire pressure value flashing. After the original road
tire has been properly repaired and put back onto the
vehicle in place of the non-matching full size spare tire,
the TPMS will update the graphic display on the EVIC
with a new tire pressure value instead of the flashing low
tire pressure value, and the “Tire Pressure MonitoringTelltale Light” will be OFF as long as none of the road
tire(s) are below the low pressure warning threshold. The
vehicle may need to be driven for up to 10 minutes above
15 mph (24 km/h) to receive this information.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
After-market wheels can cause sensor damage. Do

Spare Tire Removal
Fit the jack handle extension over the drive nut. Use the
Lug Wrench to rotate the nut counter clockwise until the
spare is on the ground with enough slack in the cable to
allow to pull the tire out from under the vehicle.
CAUTION!
The winch mechanism is designed for use with the
jack extension tube only. Use of an air wrench or
other power tools is not recommended and can
damage the winch.
When the spare is clear, tilt the retainer at the end of the
cable and pull it through the center of the wheel.
Preparations For Jacking
Park the vehicle on a firm level surface, avoid ice or
slippery areas,set the parking brakeand place the gear
selector in P (Park). Turn OFF the ignition.
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.
•Turn on the Hazard Warning Flasher.
•Block both the front and rear
of the wheel diagonally oppo-
site of the jacking position.
344 WHAT TO DO IN EMERGENCIES

For example, if changing the right front tire, block the
left rear wheel.
•Passengers should not remain in the vehicle when the
vehicle is being jacked.
Jacking Instructions
1. Remove the spare tire, jack, and tools from storage.
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.3. Assemble the jack and jacking tools as shown. Connect
jack handle driver (A) to two extensions (B), then to the
lug wrench (C).

4. Locate the jack as shown. For the front axle, place it
under the front lower control arm as shown. For the rear
axle, place it under the axle near the wheel to be changed.
Ensure the jack is closest to the inside of the wheel when
jacking on the rear axle.Do not raise the vehicle until
you are sure the jack is fully engaged.
5. Raise the vehicle by turning the jack screw clockwise.
Raise the vehicle only until the tire just clears the surface
and enough clearance is obtained to install the spare tire.
Minimum tire lift provides maximum stability.

346 WHAT TO DO IN EMERGENCIES

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.
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 nuts. To avoid the risk of forcing the
vehicle off the jack, do not tighten the nuts fully until the
vehicle has been lowered.
8. Lower the vehicle by turning the jack screw counter
clockwise, and remove the jack and wheel blocks.9. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
nuts until each nut has been tightened twice. Correct
wheel nut tightness is 130 N·m (95 ft. lbs). If in doubt
about the correct tightness, have them checked with a
torque wrench by your authorized dealer or at a service
station.
10. Lower the jack to it’s fully closed position.
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.
11. Secure the tire, jack, and tools in their proper loca-
tions.
