2013 JEEP GRAND CHEROKEE tire type

WARNING!
Do not use the cargo tie downs located on
the load floor. Improper usage of the tether
can lead to a failure of an infant or child
restraint. The child could be badly injured or
killed.
Many, but not all, restraint systems will be
equipped with separate straps on each side,
with each having a hook or connector for attach-
ment to the lower anchorage and a means of
adjusting the tension in the strap. Forward-
facing toddler restraints and some rear-facing
infant restraints will also be equipped with a
tether strap, a hook for attachment to the tether
strap anchorage and a means of adjusting the
tension of the strap.
First, loosen the child seat adjusters on the
lower straps and on the tether strap so that you
can more easily attach the hooks or connectors
to the vehicle anchorages. Next, attach the
lower hooks or connectors over the top of the
anchorage bars, pushing aside the seat cover material. Then, locate the tether anchorage
directly behind the seat where you are placing
the child restraint and attach the tether strap to
the anchorage, being careful to route the tether
strap to provide the most direct path between
the anchor and the child restraint.
There are
two top tether anchorages located on the
back of the seat, behind the gap panel. They
are not visible until you fold the gap panel
down. Do not use the cargo tie down hooks
located on the floor behind the seat. Finally,
tighten both straps as you push the child re-
straint rearward and downward into the seat,
removing slack in the straps according to the
child restraint manufacturer’s instructions.
WARNING!
Improper installation of a child restraint to the
ISOFIX anchorages can lead to failure of an
infant or child restraint. The child could be
badly injured or killed. Follow the manufac-
turer’s directions exactly when installing an
infant or child restraint. Installing Child Restraints Using The
Vehicle Seat Belts
The seat belts in the passenger seating positions
are equipped with an Automatic Locking Retractor
(ALR to secure a Child Restraint System (CRS).
These types of seat belts are designed to keep the
lap portion of the seat belt tight around the child
restraint so that it is not necessary to use a locking
clip. The ALR will make a ratcheting noise if you
extract the entire belt from the retractor and then
allow the belt to retract into the retractor. For
additional information on ALR, refer to “Automatic
Locking Mode” description under “Seat Belts in
Passenger Seating Positions” section. The chart
below defines the seating positions with an Auto-
matic Locking Retractor (ALR) or a cinching latch
plate.

11. Tire Pressure Monitoring Telltale LightEach tire, including the spare (if
provided), should be checked
monthly when cold and inflated
to the inflation pressure recom-
mended by the vehicle manufac-
turer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitoring
System (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi-
mately one minute and then remain continu-
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
CAUTION!
The TPMS has been optimized for the origi-
nal equipment tires and wheels. TPMS pres-
sures and warning have been established for
the tire size equipped on your vehicle. Un-
desirable system operation or sensor dam-
age may result when using replacement
equipment that is not of the same size, type,
and/or style. Aftermarket 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.

odometer line and outside temperature are dis-
played.
2. The main display area where the menus and
pop up messages are displayed.
3. The reconfigurable telltales section below
the odometer line.
The main display area will normally display the
main menu or the screens of a selected feature of
the main menu. The main display area also
displays"pop up" messages that consist of ap-
proximately 60 possible warning or information messages. These pop up messages fall into
several categories:
•
Five Second Stored Messages
When the appropriate conditions occur, this
type of message takes control of the main
display area for five seconds and then returns to
the previous screen. Most of the messages of
this type are then stored (as long as the condi-
tion that activated it remains active) and can be
reviewed from the "Messages"main menu item.
As long as there is a stored message, an "i"will
be displayed in the EVIC’s compass/outside
temp line. Examples of this message type are
"Right Front Turn Signal Lamp Out" and"Low
Tire Pressure".
• Unstored Messages
This message type is displayed indefinitely or
until the condition that activated the message is
cleared. Examples of this message type are
"Turn Signal On" (if a turn signal is left on) and
"Lights On" (if driver leaves the vehicle).
169

•Unstored Messages Until RUN
These messages deal primarily with the Re-
mote Start feature. This message type is dis-
played until the ignition is in the RUN state.
Examples of this message type are "Remote
Start Aborted - Door Ajar" and"Press Brake
Pedal and Push Button to Start".
• Five Second Unstored Messages
When the appropriate conditions occur, this
type of message takes control of the main
display area for five seconds and then returns to
the previous screen. Examples of this message
type are "Memory System Unavailable - Not in
Park" and"Automatic High Beams On".
The Reconfigurable Telltales section is divided
into the white telltales area on the right, amber
telltales in the middle, and red telltales on the left.
When the appropriate conditions exist, the
EVIC displays the following messages:

•If the vehicle has not been driven for
several days, the first few seconds of
operation after shifting the transmission
into gear may seem sluggish. This is due
to the fluid partially draining from the
torque converter into the transmission.
This condition is normal and will not
cause damage to the transmission. The
torque converter will refill within five sec-
onds after starting the engine.
FOUR-WHEEL DRIVE
OPERATION
Quadra-Trac II® Operating
Instructions/Precautions
The Quadra-Trac II® transfer case is fully auto-
matic in the normal driving 4WD AUTO mode.
The Quadra-Trac II® transfer case provides
three mode positions:
•4WD HI
• NEUTRAL
• 4WD LOW This transfer case is fully automatic in the 4WD
HI mode.
When additional traction is required, the 4WD
LOW position can be used to lock the front and
rear driveshafts together and force the front and
rear wheels to rotate at the same speed. The
4WD LOW position is intended for loose, slip-
pery road surfaces only. Driving in the 4WD
LOW position on dry, hard-surfaced roads may
cause increased tire wear and damage to drive-
line components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that
of the 4WD HI position at a given road speed.
Take care not to overspeed the engine and do
not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and cir-
cumference on each wheel. Any difference will
adversely affect shifting and cause damage to
the transfer case.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go faster
than road conditions permit.
WARNING!
You or others could be injured if you leave
the vehicle unattended with the transfer case
in the NEUTRAL (N) position without first
fully engaging the parking brake. The trans-
fer case NEUTRAL (N) position disengages
both the front and rear driveshafts from the
powertrain and will allow the vehicle to move
regardless of the transmission position. The
parking brake should always be applied
when the driver is not in the vehicle.

Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable
ride. Over-inflation produces a jarring and un-
comfortable ride. Both under-inflation and over-
inflation affect the stability of the vehicle and
can produce a feeling of sluggish response or
over responsiveness in the steering.
Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
Tire Inflation PressuresThe proper cold tire inflation pressure is listed
on the driver’s side “B” Pillar or rear edge of the
driver’s side door.
At least once a month:
•Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgement when determining
proper inflation. Tires may look properly in-
flated even when they are under-inflated.
• Inspect tires for signs of tire wear or visible
damage.
CAUTION!
After inspecting or adjusting the tire pres-
sure, always reinstall the valve stem cap.
This will prevent moisture and dirt from en-
tering the valve stem, which could damage
the valve stem.
Inflation pressures specified on the placard are
always “cold tire inflation pressure.” Cold tire
inflation pressure is defined as the tire pressure
after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km)
after a three hour period. The cold tire inflation
pressure must not exceed the maximum infla-
tion pressure molded into the tire sidewall.
Check tire pressures more often if subject to a
wide range of outdoor temperatures, as tire
pressures vary with temperature changes.
Tire pressures change by approximately 1 psi
(7 kPa) per 12°F (7°C) of air temperature
change. Keep this in mind when checking tire
pressure inside a garage, especially in the
winter. Example: If garage temperature = 68°F (20°C)
and the outside temperature = 32°F (0°C) then
the cold tire inflation pressure should be in-
creased by 3 psi (21 kPa), which equals 1 psi
(7 kPa) for every 12°F (7°C) for this outside
temperature condition.
Tire pressure may increase from 2 to 6 psi (13
to 40 kPa) during operation. DO NOT reduce
this normal pressure build up or your tire pres-
sure will be too low.
Tire Pressures For High Speed
Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits. Where
speed limits or conditions are such that the
vehicle can be driven at high speeds, maintain-
ing correct tire inflation pressure is very impor-
tant. Increased tire pressure and reduced ve-
hicle loading may be required for high-speed
vehicle operation. Refer to your authorized tire
or original equipment vehicle dealer for recom-
mended safe operating speeds, loading and
cold tire inflation pressures.
260

WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to fail.
You could have a serious collision. Do not
drive a vehicle loaded to the maximum ca-
pacity at continuous speeds above 75 mph
(120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types of
tires on your vehicle will cause your vehicle
to handle poorly. The instability could cause
a collision. Always use radial ply tires in sets
of four. Never combine them with other types
of tires.
Cuts and punctures in radial tires are repairable
only in the tread area because of sidewall
flexing. Consult your authorized tire dealer for
radial tire repairs.
All Season Tires – If EquippedAll Season tires provide traction for all seasons
(spring, summer, fall and winter). Traction levels
may vary between different all season tires. All
season tires can be identified by the M+S, M&S,
M/S or MS designation on the tire sidewall. Use
all season tires only in sets of four; failure to do
so may adversely affect the safety and handling
of your vehicle.
Summer Or Three Season Tires – If
Equipped
Summer tires provide traction in both wet and
dry conditions, and are not intended to be
driven in snow or on ice. Summer tires will not
contain the all season designation or mountain/
snowflake symbol on the tire sidewall. Use
summer tires only in sets of four; failure to do so
may adversely affect the safety and handling of
your vehicle.
Snow TiresSome areas of the country require the use of
snow tires during the winter. Snow tires can be
identified by a mountain/snowflake symbol on
the tire sidewall.
If you need snow tires, select tires equivalent in
size and type to the original equipment tires.
Use snow tires only in sets of four; failure to do
so may adversely affect the safety and handling
of your vehicle.
Snow tires generally have lower speed ratings
than what was originally equipped with your
vehicle and should not be operated at sustained
speeds over 75 mph (120 km/h). For speeds
above 75 mph (120 km/h) refer to original
equipment or an authorized tire dealer for rec-
ommended safe operating speeds, loading and
cold tire inflation pressures.
While studded tires improve performance on
ice, skid and traction capability on wet or dry
surfaces may be poorer than that of non-
studded tires. Some states prohibit studded
tires; therefore, local laws should be checked
before using these tire types.
261

WARNING!(Continued)
•Never use a tire with a smaller load index
or capacity, other than what was originally
equipped on your vehicle. Using a tire with
a smaller load index could result in tire
overloading and failure. You could lose
control and have a collision.
• Failure to equip your vehicle with tires
having adequate speed capability can re-
sult in sudden tire failure and loss of ve-
hicle control.
CAUTION!
Replacing original tires with tires of a differ-
ent size may result in false speedometer and
odometer readings.
TIRE CHAINS (TRACTION
DEVICES)
Use of traction devices require sufficient tire-to-
body clearance. Follow these recommenda-
tions to guard against damage.
• Traction device must be of proper size for the
tire, as recommended by the traction device
manufacturer.
• Install on Rear Tires Only
• Due to limited clearance, use reduced size
snow chains or traction devices with a maxi-
mum projection of 6 mm beyond the tire
profile.
WARNING!
Using tires of different size and type (M+S,
Snow) between front and rear axles can cause
unpredictable handling. You could lose control
and have a collision.
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
•Because of restricted traction device clear-
ance between tires and other suspension
components, it is important that only trac-
tion devices in good condition are used.
Broken devices can cause serious dam-
age. Stop the vehicle immediately if noise
occurs that could indicate device break-
age. Remove the damaged parts of the
device before further use.
• Install device as tightly as possible and
then retighten 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 prolonged period on dry
pavement.
