2016 JEEP GRAND CHEROKEE spare tire

worn to the tread wear indicators, the tire should be
replaced. Refer to “Replacement Tires” in this section for
further information.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style.
•
Tire pressure - Improper cold tire inflation pressures can
cause uneven wear patterns to develop across the tire
tread. These abnormal wear patterns will reduce tread
life, resulting in the need for earlier tire replacement.
• Distance driven.
• Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle main-
tenance schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have a collision resulting
in serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressures. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. Refer to the paragraph on
“Tread Wear Indicator”. Refer to the Tire and Loading

damage. Stop the vehicle immediately if noise
occurs that could indicate device breakage. Remove
the damaged parts of the device before further use.
• Install device as tightly as possible and then re-
tighten after driving about ½ mile (0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
• Do not drive for a prolonged period on dry pave-
ment.
• Observe the traction device manufacturer ’s instruc-
tions on the method of installation, operating
speed, and conditions for use. Always use the
suggested operating speed of the device manufac-
turer ’s if it is less than 30 mph (48 km/h).
• Do not use traction devices on a compact spare tire.
TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on On/Off-Road
type tires. Rotation will increase tread life, help to main-
tain mud, snow, and wet traction levels, and contribute to
a smooth, quiet ride.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed.
546 STARTING AND OPERATING

1. Jamming due to electronic devices or driving next tofacilities emitting the same Radio Frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors. NOTE:
•
There is no 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 warn-
ing limit, upon the next ignition switch cycle, the Tire
Pressure Monitoring Telltale Light will remain ON, a
chime will sound, and the DID will still display a
different color pressure value in the graphic display.
An Inflate to XXX message will still be displayed.
• 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 DID will display
a “SERVICE TPM SYSTEM message for a minimum of
five seconds and then display dashes (- -) in place of
the pressure value. 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 DID 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 DID 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
This device complies with Part 15 of the FCC rules and
RSS-210 of Industry Canada. Operation is subject to the
following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause undesired op-
eration.
NOTE: Changes or modifications not expressly approved
by the party responsible for compliance could void the
user ’s authority to operate the equipment.
554 STARTING AND OPERATING

3. There is no fuel filler cap. A flapper door inside thepipe seals the system.
4. Insert the fuel nozzle fully into the filler pipe, the nozzle opens and holds the flapper door while refuel-
ing.
5. Fill the vehicle with fuel, when the fuel nozzle “clicks” or shuts off the fuel tank is full.
6. Wait 5 seconds before removing the fuel nozzle to allow fuel to drain from nozzle.
7. Remove the fuel nozzle and close the fuel door.
Emergency Gas Can Refueling
• Most gas cans will not open the flapper door.
• A funnel is provided to open the flapper door to allow
emergency refueling with a gas can. •
Retrieve funnel from the spare tire storage area.
• Insert funnel into same filler pipe opening as the fuel
nozzle.
• Ensure funnel is inserted fully to hold flapper door
open.
• Pour fuel into funnel opening.
• Remove funnel from filler pipe, clean off prior to
putting back in the spare tire storage area.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.

NOTE:The funnel for the Cap-Less Fuel System is
located on top of the spare tire. If your vehicle is out of
fuel and an auxiliary fuel can is needed, insert the funnel
into the filler neck and proceed to fill the vehicle. For
vehicles not equipped with a spare tire, the fuel filler
funnel is stored in the left storage bin under the load
floor. For more information on the Cap-Less Fuel System
refer to “Adding Fuel” in “Starting And Operating” in
this manual.
Spare Tire Stowage
The spare tire is stowed under the load floor in the rear
cargo area and is secured to the body with a special wing
nut.
Preparations For Jacking
CAUTION!
Always lift or jack the vehicle from the correct
jacking points. Failure to follow this information
could cause damage to the vehicle or underbody
components.
1. Park the vehicle on a firm, level surface. Avoid ice or slippery surfaces.
WARNING!
Do not attempt to change a tire on the side of the
vehicle closest 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.

WARNING!(Continued)
•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 the ground.
CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the Jacking
Instructions for this vehicle.
