2015 JEEP CHEROKEE ABS

The ABS pump motor runs during the self-test at 12 mph
(20 km/h) and during an ABS stop. The pump motor
makes a low humming noise during operation, which is
normal.
WARNING!
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
•The ABS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or
the traction afforded.

WARNING!(Continued)
•The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety or
the safety of others.
CAUTION!
The ABS is subject to possible detrimental effects of
electronic interference caused by improperly in-
stalled aftermarket radios or telephones.
NOTE:During severe braking conditions, a pulsing sen-
sation may occur and a clicking noise will be heard. This
is normal, indicating that the ABS is functioning.

wheel. This will allow more engine torque to be applied
to the wheel that is not spinning. This feature remains
active even if TCS and ESC are in the “Partial Off” mode
or the “Full Off” mode. Refer to “Electronic Stability
Control (ESC)” in this section for further information.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous brak-
ing pressure during the stopping sequence, (do not
“pump” the brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. BAS cannot prevent collisions, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. The capabilities of a BAS-equipped vehicle
must never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety or
the safety of others.
522 STARTING AND OPERATING

NOTE:
•P (Passenger) — Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
•European — Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letter#P#is absent from this tire
size designation. Example: 215/65R15 96H.
•LT (Light Truck) — Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
•Temporary spare tires are designed for temporary
emergency use only. Temporary high pressure com-
pact spare tires have the letter “T” or “S” molded into
the sidewall preceding the size designation. Example:
T145/80D18 103M.
•High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.

STARTING AND OPERATING 541

EXAMPLE:
Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL)
tire:
•XL= Extra load (or reinforced) tire, or
•LL= Light load tire or
•C, D, E, F, G= Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load– Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure– Maximum pressure indicates the maximum permissible cold tire inflation pressure for this
tire
Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire,
however, the date code may only be on one side. Tires
with white sidewalls will have the full TIN, including the
date code, located on the white sidewall side of the tire.
Look for the TIN on the outboard side of black sidewall
tires as mounted on the vehicle. If the TIN is not found on
the outboard side, then you will find it on the inboard
side of the tire.

WARNING!(Continued)
•Keep Tire Service Kit away from open flames or
heat source.
•A loose Tire Service Kit thrown forward in a
collision or hard stop could endanger the occupants
of the vehicle. Always stow the Tire Service Kit in
the place provided. Failure to follow these warn-
ings can result in injuries that are serious or fatal to
you, your passengers, and others around you.
•Take care not to allow the contents of Tire Service
Kit to come in contact with hair, eyes, or clothing.
Tire Service Kit is harmful if inhaled, swallowed,
or absorbed through the skin. It causes skin, eye,
and respiratory irritation. Flush immediately with
plenty of water if there is any contact with eyes or
skin. Change clothing as soon as possible, if there
is any contact with clothing.

WARNING!(Continued)
•Tire Service Kit Sealant solution contains latex. In
case of an allergic reaction or rash, consult a phy-
sician immediately. Keep Tire Service Kit out of
reach of children. If swallowed, rinse mouth imme-
diately with plenty of water and drink plenty of
water. Do not induce vomiting! Consult a physician
immediately.
Sealing A Tire With Tire Service Kit
(A) Whenever You Stop To Use Tire Service Kit:
1. Pull over to a safe location and turn on the vehicle’s
Hazard Warning flashers.
2. Verify that the valve stem (on the wheel with the
deflated tire) is in a position that is near to the ground.
This will allow the Tire Service Kit Hoses (6) and (7) to
reach the valve stem and keep the Tire Service Kit flat

4. Remove the air cleaner filter element from the housing
assembly.
Engine Air Cleaner Filter Installation
NOTE:Inspect and clean the housing if dirt or debris is
present before replacing the air filter element.
1. Install the air cleaner filter element into the housing
assembly with the air cleaner filter inspection surface
facing downward.
2. Install the air cleaner cover onto the housing assembly
locating tabs.
3. Install screws to secure the air cleaner cover to the
housing assembly and install air hose.

WARNING!(Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that has
been in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in a open container absorbs moisture from the
air resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or pro-
longed braking, resulting in sudden brake failure.
This could result in a collision.
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.
(Continued)
WARNING!(Continued)
•Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer’s specified transmission fluid.
Refer to “Fluids, Lubricants, and Genuine Parts” in this
section for fluid specifications. It is important to maintain
the transmission fluid at the correct level using the
recommended fluid.
