2015 JEEP CHEROKEE tire type

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
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem 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 original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement 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.

4. EVIC Display Area
The EVIC display area will normally display the main
menu or the screens of a selected feature of the main
menu. The EVIC display area also displays “pop up”
messages that consist of approximately 60 possible warn-
ing 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 condition 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 Pres-
sure”.
•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).
•Unstored Messages Until RUN
These messages deal primarily with the Remote Start
feature. This message type is displayed 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.
An example of this message type is “Automatic High
Beams On”.

The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
5. Driver Information Display (DID)
The DID display area will normally display the main
menu or the screens of a selected feature of the main
menu. The DID display area also displays “pop up”
messages that consist of approximately 60 possible warn-
ing 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 condition 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 middle of the DID’s top
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).
•Unstored Messages Until RUN
These messages deal primarily with the Remote Start
feature. This message type is displayed 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”.

STARTING AND OPERATING 469

Additionally, on dry pavement under heavy throttle
input (where one may have no wheel spin), torque will be
sent to the rear in a pre-emptive effort to improve vehicle
launch and performance characteristics.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the power transfer unit.

STARTING AND OPERATING 495

The Four-Wheel Drive is fully automatic in the normal
driving mode. The Selec-Terrain buttons provide three
selectable mode positions:
•4WD LOW
•REAR LOCK (If Equipped)
•NEUTRAL
When additional traction is required, the 4WD LOW
range position can be used to provide an additional gear
reduction which allows for increased torque to be deliv-
ered to both the front and rear wheels. 4WD LOW is
intended for loose, slippery road surfaces only. Driving in
4WD LOW on dry, hard-surfaced roads may cause in-
creased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the normal
driving mode 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 circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the driveline components.

ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system commonly referred to as ESC. This
system includes Anti-Lock Brake System (ABS), Traction
Control System (TCS), Brake Assist System (BAS), Hill
Start Assist (HSA), Electronic Roll Mitigation (ERM), and
Electronic Stability Control (ESC). These systems work
together to enhance both vehicle stability and control in
various driving conditions.
Your vehicle is also equipped with Trailer Sway Control
(TSC), Ready Alert Braking (RAB) and Rain Brake Sup-
port (RBS). Further, all vehicles equipped with a two-
speed power transfer unit have Hill Descent Control
(HDC) and some vehicles may also be equipped with
Selec Speed Control (SSC).
Anti-Lock Brake System
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure, to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
All vehicle wheels and tires must be the same size and
type, and tires must be properly inflated, to produce
accurate signals for the computer.
WARNING!
Significant over or under-inflation of tires or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.
The ABS conducts a low-speed self-test at about 12 mph
(20 km/h). If you have your foot lightly on the brake
while this test is occurring, you may feel slight pedal
movement. The movement can be more apparent on ice
and snow. This is normal.

STARTING AND OPERATING 519

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 inflated even when they are under-
inflated.
•Inspect tires for signs of tire wear or visible damage.
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering 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 sitting for a minimum of three hours.
The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire side-
wall.
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 increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
