JEEP GRAND CHEROKEE 2015 WK2 / 4.G Owners Manual

WARNING!(Continued)
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service, or immedi-
ately if the brake system warning lamp indicates system
failure.
The brake master cylinder has a plastic reservoir. On the
outboard side of the reservoir, there is a “MAX” dot and
a “MIN” dot. The fluid level must be kept within these
two dots. Do not add fluid above the MAX mark, because
leakage may occur at the cap.
With disc brakes, the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also identified on the
original factory installed hydraulic master cylinder
reservoir.

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.
Front/Rear Axle Fluid
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the axle assembly should be
inspected. If gear oil leakage is suspected inspect the
fluid level. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion.
Front Axle Fluid Level Check
The front axle oil level needs to be no lower than 1/8 in
(3 mm) below the bottom of the fill hole.
640 MAINTAINING YOUR VEHICLE

The front axle fill and drain plugs should be tightened to
22 to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.
Rear Axle Fluid Level Check
The rear axle oil level needs to be no lower than 1/8 in
(3 mm) below the bottom of the fill hole.
The rear axle fill and drain plugs should be tightened to
22 to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid. Refer
to “Fluids, Lubricants, and Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
Transfer Case
Fluid Level Check
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the transfer case assembly should
be inspected. If oil leakage is suspected inspect the fluid
level. Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Adding Fluid
Add fluid at the filler hole, until it runs out of the hole,
when the vehicle is in a level position.

MAINTAINING YOUR VEHICLE 641

Drain
First remove fill plug, then remove drain plug. Recom-
mended tightening torque for drain and fill plugs is 15 to
25 ft lbs (20 to 34 N·m).
CAUTION!
When installing plugs, do not overtighten. You could
damage them and cause them to leak.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid. Refer
to “Fluids, Lubricants, and Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
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.
NOTE:No chemical flushes should be used in any
transmission; only the approved lubricant should be
used.
CAUTION!
Using a transmission fluid other than the manufac-
turer ’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for fluid specifications.
642 MAINTAINING YOUR VEHICLE

Special Additives
The manufacturer strongly recommends against using
any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. The only exception to this
policy is the use of special dyes for diagnosing fluid
leaks. Avoid using transmission sealers as they may
adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine
fluid level checks are not required, therefore the transmis-
sion has no dipstick. Your authorized dealer can check your
transmission fluid level using special service tools.
If you notice fluid leakage or transmission malfunction,
visit your authorized dealer immediately to have the
transmission fluid level checked. Operating the vehicle
with an improper fluid level can cause severe transmis-
sion damage.
CAUTION!
If a transmission fluid leak occurs, visit your autho-
rized dealer immediately. Severe transmission dam-
age may occur. Your authorized dealer has the proper
tools to adjust the fluid level accurately.

MAINTAINING YOUR VEHICLE 643

Fluid And Filter Changes
Under normal operating conditions, the fluid installed at
the factory will provide satisfactory lubrication for the
life of the vehicle.
Routine fluid and filter changes are not required. How-
ever, change the fluid and filter if the fluid becomes
contaminated (with water, etc.), or if the transmission is
disassembled for any reason.
Appearance Care And Protection From Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and chemicals that are sprayed
on trees and road surfaces during other seasons, are
highly corrosive to the metal in your vehicle. Outside
parking, which exposes your vehicle to airborne contami-
nants, road surfaces on which the vehicle is operated,
extreme hot or cold weather and other extreme condi-
tions will have an adverse effect on paint, metal trim, and
underbody protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.
The most common causes are:
•Road salt, dirt and moisture accumulation.
•Stone and gravel impact.
•Insects, tree sap and tar.
•Salt in the air near seacoast localities.
•Atmospheric fallout/industrial pollutants.
644 MAINTAINING YOUR VEHICLE

Washing
•Wash your vehicle regularly. Always wash your ve-
hicle in the shade using MOPAR® Car Wash, or a mild
car wash soap, and rinse the panels completely with
clear water.
•If insects, tar, or other similar deposits have accumu-
lated on your vehicle, use MOPAR® Super Kleen Bug
and Tar Remover to remove.
•Use a high quality cleaner wax, such as MOPAR®
Cleaner Wax to remove road film, stains and to protect
your paint finish. Take care never to scratch the paint.
•Avoid using abrasive compounds and power buffing
that may diminish the gloss or thin out the paint finish.
CAUTION!
•Do not use abrasive or strong cleaning materials
such as steel wool or scouring powder that will
scratch metal and painted surfaces.
•Use of power washers exceeding 1,200 psi
(8 274 kPa) can result in damage or removal of paint
and decals.
Special Care
•If you drive on salted or dusty roads or if you drive
near the ocean, hose off the undercarriage at least once
a month.
•It is important that the drain holes in the lower edges
of the doors, rocker panels, and trunk be kept clear and
open.

MAINTAINING YOUR VEHICLE 645

•If you detect any stone chips or scratches in the paint,
touch them up immediately. The cost of such repairs is
considered the responsibility of the owner.
•If your vehicle is damaged due to a collision or similar
cause that destroys the paint and protective coating,
have your vehicle repaired as soon as possible. The
cost of such repairs is considered the responsibility of
the owner.
•If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., be sure that such materials are well
packaged and sealed.
•If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.
•Use MOPAR® Touch Up Paint on scratches as soon as
possible. Your authorized dealer has touch up paint to
match the color of your vehicle.
Wheel And Wheel Trim Care
•All wheels and wheel trim, especially aluminum and
chrome plated wheels, should be cleaned regularly
with a mild soap and water to prevent corrosion.
•To remove heavy soil and/or excessive brake dust, use
MOPAR® Wheel Cleaner.
NOTE:If your vehicle is equipped with Dark Vapor or
Black Satin Chrome wheels DO NOT USE wheel cleaners,
abrasives or polishing compounds. They will perma-
nently damage this finish and such damage is not cov-
ered by the New Vehicle Limited Warranty. USE ONLY
MILD SOAP AND WATER WITH A SOFT CLOTH. Used
on a regular basis this is all that is required to maintain
this finish.
646 MAINTAINING YOUR VEHICLE

CAUTION!
Do not use scouring pads, steel wool, a bristle brush,
or metal polishes. Do not use oven cleaner. These
products may damage the wheel’s protective finish.
Avoid automatic car washes that use acidic solutions
or harsh brushes that may damage the wheel’s pro-
tective finish. Only MOPAR® Wheel Cleaner or
equivalent is recommended.
Stain Repel Fabric Cleaning Procedure — If
Equipped
Stain Repel seats may be cleaned in the following man-
ner:
•Remove as much of the stain as possible by blotting
with a clean, dry towel.
•Blot any remaining stain with a clean, damp towel.
•For tough stains, apply MOPAR® Total Clean, or a
mild soap solution to a clean, damp cloth and remove
stain. Use a fresh, damp towel to remove soap residue.
•For grease stains, apply MOPAR® Multi-Purpose
Cleaner to a clean, damp cloth and remove stain. Use
a fresh, damp towel to remove soap residue.
•Do not use any harsh solvents or any other form of
protectants on Stain Repel products.
Interior Care
Use MOPAR® Total Clean to clean fabric upholstery and
carpeting.
Use MOPAR® Total Clean to clean vinyl upholstery.
MOPAR® Total Clean is specifically recommended for
leather upholstery.
7
MAINTAINING YOUR VEHICLE 647

Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt
can act as an abrasive and damage the leather upholstery
and should be removed promptly with a damp cloth.
Stubborn soils can be removed easily with a soft cloth
and MOPAR® Total Clean. Care should be taken to avoid
soaking your leather upholstery with any liquid. Please
do not use polishes, oils, cleaning fluids, solvents, deter-
gents, or ammonia-based cleaners to clean your leather
upholstery. Application of a leather conditioner is not
required to maintain the original condition.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas they may cause respiratory harm.
CAUTION!
Do not use Alcohol and Alcohol-based and/or Keton
based cleaning products to clean leather seats, as
damage to the seat may result.
Cleaning Headlights
Your vehicle is equipped with plastic headlights and fog
lights that are lighter and less susceptible to stone break-
age than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other aggressive material to clean the lenses.
