AUTOMATIC TRANSMISSION
FLUID CHECK
The transmission does not consume fluid.
However, the fluid level should be checked
if the transmission is not working properly,
for example if the transmission slips, shifts
slowly or if there are signs of fluid loss.
The transmission fluid and filter on your
vehicle must be replaced at the specified
service interval. See Scheduled
Maintenance (page 322).
Automatic transmission fluid expands
when warmed. To check the fluid level
consistently and accurately, do the
following:
1. Drive the vehicle until it reaches normal
operating temperature. This may take
up to
20 mi (30 km).
2. Make sure that your vehicle is on level ground.
3. With the engine running, parking brake
engaged and your foot on the brake
pedal, move the gearshift lever through
all of the gear ranges. Allow sufficient
time for each gear to engage.
4. Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N) and leave the engine
running.
5. Open the hood. See
Opening and
Closing the Hood (page 188).
6. Remove the dipstick and wipe it with a clean, lint-free cloth. See
Under
Hood Overview (page 191).
7. Replace the dipstick and remove it again to check the fluid level.
8. If the fluid level is correct, replace the dipstick and make sure it is fully seated.
Note: If the fluid level is between the
maximum and minimum marks, the fluid
level is acceptable. Do not add fluid. Transmission Fluid Level
Low Fluid Level
If the fluid level is at or below the minimum
mark, add fluid immediately. See
Capacities and Specifications
(page
261).
Note: If there is no indication of fluid on the
dipstick, have your vehicle checked
immediately.
Correct Fluid Level Make sure that the fluid level is between
the maximum and minimum marks.

F650750 (TBC) , enUSA, Edition date: 201804, Second-Printing MaintenanceE163740 E163742

High Fluid Level
Do not add fluid further than the maximum
mark. Fluid levels above the maximum
mark may cause shift or engagement
concerns and possible damage.
Note:
High fluid levels can be caused by an
overheating condition.
Adding Transmission Fluid
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components and could lead to
transmission damage that may not be
covered by the vehicle Warranty.
Use only recommended transmission fluid
that meets our specifications. See
Capacities and Specifications (page
261).
Note: Use of a non-approved automatic
transmission fluid may cause internal
transmission component damage.
If necessary, add fluid in
8 fl oz (250 ml)
increments through the filler tube until the
level is correct.
If an overfill occurs, excess fluid should be
removed, have your vehicle checked as
soon as possible. BRAKE FLUID CHECK WARNING:
Do not use any fluid
other than the recommended brake fluid
as this will reduce brake efficiency. Use
of incorrect fluid could result in the loss
of vehicle control, serious personal injury
or death. WARNING:
Only use brake fluid
from a sealed container. Contamination
with dirt, water, petroleum products or
other materials may result in brake
system damage or failure. Failure to
adhere to this warning could result in the
loss of vehicle control, serious personal
injury or death. WARNING:
Do not allow the fluid
to touch your skin or eyes. If this
happens, rinse the affected areas
immediately with plenty of water and
contact your physician. WARNING:
A fluid level between
the MAX and MIN lines is within the
normal operating range and there is no
need to add fluid. A fluid level not in the
normal operating range could
compromise the performance of the
system. Have your vehicle checked
immediately.

SUSPENSION SYSTEM
INSPECTION
Note:
Do not adjust air suspension height
to any setting other than the specified
setting. Altering the height setting changes
the driveline angle and may result in
unwarrantable component damage, such
as transmission component damage.
Verify drive axle air suspension height and
height control valve performance at engine
oil change intervals.
Periodically check:
• Condition of spring leaves for evidence
of fatigue, bending or breakage.
• Condition of suspension mounting
brackets and bushings.
• Torque rod mounting fasteners for
tightness.
• For proper suspension alignment.
Maintain proper alignment at all times.
• U-bolts. After the chassis has been
operating under load for 1,000 mi
(1,600 km) or six months (whichever
comes first), the U-bolt nuts must be
re-torqued. Re-torque the U-bolt nuts
every
37,000 mi (60,000 km)
thereafter. Clean and lubricate the
U-bolt and nut threads and seats to
make sure a like new condition when
re-torqueing. See
Spring U-Bolt
Check (page 228).
FRAME AND TOW HOOK
INSPECTION
Your vehicle's chassis is manufactured
with frame rails of either HSLA steel or
heat-treated steel. Handle each in a
specific manner to make sure maximum
service life. Consult the service manual or
an authorized dealer before attempting
frame repair or modification. It is important, particularly on vehicles that
use tow hooks frequently, to inspect the
front and rear tow hooks for damage or a
loose mounting.
REAR AXLE FLUID CHECK
Your rear axle may have an optional
synthetic lubricant that allows the use of
extended service intervals. A tag on the
filler plug identifies the use of the synthetic
lubricant.
Only use a lubricant that meets
manufacturer specifications. Only use a
lubricant that meets manufacturer
specifications. Use of a non-approved rear
axle lubricant may cause internal axle
component damage. See Capacities and
Specifications
(page 261).
Checking the Fluid Level
1. Park your vehicle on level ground.
2. Set the parking brake and shift into position neutral (N) or park (P). Turn
the engine off.
3. Clean any dirt from around the axle filler plug.
4. Remove the filler plug and inspect the lubricant level. It should be at the
bottom of the filler plug opening.
5. Add lubricant, if necessary, through the
filler plug opening.
6. Clean and install the filler plug securely.
Changing the Fluid
Note: Drain the rear axle while the lubricant
is warm.
1. Park your vehicle on level ground.
2. Set the parking brake and shift into position neutral (N) or park (P). Turn
the engine off.
3. Clean any dirt from around the axle filler and drain plugs.

Be sure to ask your dealership service
advisor or technician about the multi-point
vehicle inspection. It is a comprehensive
way to perform a thorough inspection of
your vehicle. Your checklist gives you
immediate feedback on the overall
condition of your vehicle. NORMAL SCHEDULED
MAINTENANCE
Intelligent Oil-Life Monitor™
(Diesel Engine Only)
Your diesel engine is equipped with an
Intelligent Oil-Life Monitor that determines
when you should change the engine oil
based on how your vehicle is used. By using
several important factors in its
calculations, the monitor helps reduce the
cost of owning your vehicle and reduces
environmental waste at the same time.
