WARNING!Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Master Cylinder – Brake Fluid Level Check
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 translucent plastic
reservoir. On the outboard side of the reservoir, there is a
“FULL” dot and an “ADD” dot. The fluid level must be
kept within these two dots. Do not add fluid above the
full 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 for the
correct Fluid type.
WARNING!Use of a brake fluid that may have a lower initial
boiling point, or unidentified as to specification,
may result in sudden brake failure during hard
prolonged braking. You could have an accident. MAINTAINING YOUR VEHICLE 435

When checking the fluid level, the vehicle should be in a
level position. The fluid level should be 1/4” ± 1/4” (6.4
mm ± 6.4 mm) below the fill hole on the 9.25” Front Axle.
The fluid level should be 3/4” ± 1/4” (19 mm ± 6.4 mm)
below the fill hole on 11.5” Rear Axles.
Drain And Refill
Vehicles operated in normal service do not have regularly
scheduled oil changes. If fluid has become contaminated
with water or subjected to severe service, follow the
recommended change intervals in Maintenance Schedule
“B” in Section 8 of this manual.
Lubricant Selection
Refer to Fluids, Lubricants and Genuine Parts for the
correct lubricant type.
NOTE: The presence of water in the gear lubricant will
result in corrosion and possible failure of differential components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Limited-Slip Differentials in vehicles equipped with
11.5” Axles DO NOT REQUIRE any limited slip oil
additive (friction modifiers).
Transfer Case — If Equipped
Lubricant Selection
Refer to Fluids, Lubricants and Genuine Parts for the
correct lubricant type.
Fluid Level Check
This fluid level can be checked by removing the filler
plug. The fluid level should be to the bottom edge of the
filler plug hole with the vehicle in a level position. MAINTAINING YOUR VEHICLE 437

Fluid Level Check – 545RFE Transmission
Check the fluid level while the transmission is at normal
operating temperature 180° F (82° C). This occurs after at
least 15 mi (25 km) of driving. At normal operating
temperature the fluid cannot be held comfortably be-
tween the fingertips.
Procedure For Checking Fluid Level
To properly check the automatic transmission fluid level,
the following procedure must be used:
1. Operate the engine at idle speed and normal operating
temperature.
2. The vehicle must be on level ground.
3. Fully apply parking brake.
4. Place the gear selector momentarily in each gear
position ending with the lever in P (Park). 5. Remove the dipstick, wipe it clean and reinsert it until
seated.
6. Remove the dipstick again and note the fluid level on
both sides. The fluid level should be between the HOT
(upper) reference holes on the dipstick at normal operat-
ing temperature. Verify that a solid coating of oil is seen
on both sides of the dipstick. If the fluid is low, add as
required into the dipstick tube. Do not overfill. After
adding any quantity of oil through the dipstick tube, wait
a minimum of two (2) minutes for the oil to fully drain
into the transmission before rechecking the fluid level.
NOTE: If it is necessary to check the transmission below
the operating temperature, the fluid level should be
between the two cold (lower) holes on the dipstick with
the fluid at approximately 70° F (21° C) (room tempera-
ture). If the fluid level is correctly established at room
temperature, it should be between the HOT (upper) MAINTAINING YOUR VEHICLE 439

Procedure For Checking Fluid Level
To properly check the automatic transmission fluid level,
the following procedure must be used:
1. The vehicle must be on level ground.
2. Operate the engine at idle speed for a minimum of 60
seconds and normal operating temperature.
3. Fully apply parking brake and press the brake pedal.
4. Place the gear selector momentarily in each gear
position ending with the lever in P (Park). Make sure the
engine is running at idle speed.
5. Remove the dipstick and determine if the fluid is hot
or cold. Hot fluid is approximately 160° F - 175° F (70° C
– 82° C), Which is the normal operating temperature after
the vehicle has been driven at least 15 miles. The fluid can
not be comfortably held between the finger tips. Cold is
when fluid temperature is between 70 °F–85°F(20°C–
30° C). 6. Wipe the dipstick clean and reinsert it until seated.
7. Remove the dipstick again and note the fluid level on
both sides. The fluid level should be between the HOT
(upper) reference holes on the dipstick at normal operat-
ing temperature. Verify that a solid coating of oil is seen
on both sides of the dipstick. If the fluid is low, add
Mopar  A68SRC™ Automatic Transmission Fluid as
required into the dipstick tube. Do not overfill. Never
use any ATF other than Mopar  AS68RC™ Automatic
Transmission Fluid. After adding any quantity of oil
through the dipstick tube, wait a minimum of two (2)
minutes for the oil to fully drain into the transmission
before rechecking the fluid level.
NOTE: If it is necessary to check the transmission below
the operating temperature, the fluid level should be
between the two cold (lower) holes on the dipstick with
the fluid at approximately 70° F – 85° F (20° C – 30° C). If442 MAINTAINING YOUR VEHICLE

the fluid level is correctly established at room tempera-
ture, it should be between the HOT (upper) reference
holes when the transmission reaches 160° F - 175° F (70°
C – 82° C). Remember it is best to check the level at the
normal operating temperature.
CAUTION!Be aware that if the fluid temperature is below 50° F
(10° C), it may not register on the dipstick. Do not
add fluid until the temperature is elevated enough to
produce an accurate reading. Never use any ATF
other than Mopar  AS68RC™ Automatic Transmis-
sion Fluid.
8. Check for leaks. Release the Parking Brake.
NOTE: To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make certain that the dipstick cap is properly reseated. It is
normal for the dipstick cap to spring back slightly from
its fully seated positions, as long as its seal remains
engaged in the dipstick tube.
Automatic Transmission Fluid and Filter Change
To obtain best performance and long life for automatic
transmissions, the manufacturer recommends that they
be given regular maintenance service by an Authorized
Dodge Dealer or Service Center. It is important that the
transmission be adjusted periodically, the fluid main-
tained at the correct level, and that it be drained and
refilled as specified.
It is important that proper lubricant is used in the
transmission. Refer to Fluids, Lubricants and Genuine
Parts for the correct lubricant type. A band adjustment
and filter change should be made at the time of the oil
change. MAINTAINING YOUR VEHICLE 443

• Use Mopar  touch up paint on scratches as soon as
possible. Your 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 (05066247AB) or equivalent or select a
nonabrasive, non-acidic cleaner. Do not use scouring
pads, steel wool, a bristle brush, or metal polishes. Only
Mopar  or equivalent is recommended. Do not use oven
cleaner. Avoid automatic car washes that use acidic
solutions or harsh brushes that may damage the wheels’
protective finish. YES Essentials  Fabric Cleaning Procedure – If
equipped
YES Essentials  seats may be cleaned in the following
manner:
• 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 solvents or protectants on Yes Essen-

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.
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.
Cleaning Headlights
Your vehicle has plastic headlights that are lighter and
less susceptible to stone breakage 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. MAINTAINING YOUR VEHICLE 455
