2017 JEEP CHEROKEE transmission fluid

DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the Electronic Range Select
(ERS) shift control (refer toElectronic Range Select (ERS)
Operation in this section for further information) to select
a lower gear range. Under these conditions, using a lower
gear range will improve performance and extend transmis-
sion life by reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the trans-
mission shift schedule, reduce engine torque, and/or ex-
pand the range of torque converter clutch engagement.
This is done to prevent transmission damage due to
overheating. If the transmission becomes extremely hot, the “Transmis-
sion Temperature Warning Light” may illuminate and the
transmission may operate differently until the transmission
cools down.
During cold temperatures, transmission operation may be
modified depending on engine and transmission tempera-
ture as well as vehicle speed. This feature improves warm
up time of the engine and transmission to achieve maxi-
mum efficiency. Engagement of the torque converter
clutch, and shifts into 8th or 9th gear, are inhibited until the
transmission fluid is warm (refer to the note within the
“Torque Converter Clutch” topic in this section). Normal
operation will resume once the transmission temperature
has risen to a suitable level.
SPORT — If Equipped
This mode alters the transmission’s automatic shift sched-
ule for sportier driving. Upshift speeds are increased to
make full use of available engine power.
SPORT mode is activated using the rotary switch on the
center console. Refer to
Selec-Terrainin this section for
further information.

STARTING AND OPERATING 275

Moving the gear selector to the ERS position (beside DRIVE)
will activate ERS mode, display the current gear in the
instrument cluster, and set that gear as the top available gear.
Once in ERS mode, moving the gear selector forward (-) or
rearward (+) will change the top available gear.
To exit ERS mode, simply return the gear selector to the
DRIVE position.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.
NOTE: To select the proper gear position for maximum
deceleration (engine braking), move the gear selector into
the ERS position, then simply press and hold it forward (-).
The transmission will shift to the range from which the
vehicle can best be slowed down.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly different
feeling or response during normal operation in the upper
gears. When the vehicle speed drops or during some
accelerations, the clutch automatically disengages.
NOTE: The torque converter clutch will not engage until
the transmission fluid is warm (usually after 1 to 3 miles [2
to 5 km] of driving). Because the engine speed is higher
when the torque converter clutch is not engaged, it may
seem as if the transmission is not shifting properly when
cold. This is normal. The torque converter clutch will
function normally once the transmission is sufficiently
warm.

Off-Road Driving Tips
Driving Through Water
Although your vehicle is capable of driving through water,
there are a number of precautions that must be considered
before entering the water:
NOTE:When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering as a
precaution, and check all fluids afterward. Driving through
water may cause damage that may not be covered by the
New Vehicle Limited Warranty.
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and pre-
vent damage to your vehicle. If you must drive through
water, try to determine the depth and the bottom condition
(and location of any obstacles) prior to entering. Proceed
with caution and maintain a steady controlled speed less
than 5 mph (8 km/h) in deep water to minimize wave
effects.
Flowing Water
If the water is swift flowing and rising (as in storm run-off)
avoid crossing until the water level recedes and/or the
flow rate is reduced. If you must cross flowing-water,
avoid depths in excess of 9 inches (22 cm). The flowing water can erode the streambed causing your vehicle to sink
into deeper water. Determine exit point(s) that are down-
stream of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than 16 inches
(40.5 cm), and reduce speed appropriately to minimize
wave effects. Maximum speed in 16 inches (40.5 cm) of
water is less than 5 mph (8 km/h).
(Trailhawk only): Avoid driving in standing water deeper
than 19 inches (48 cm), and reduce speed appropriately to
minimize wave effects. Maximum speed in 19 inches (48
cm) of water is less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Transfer
Unit and Rear Drive Module) to assure they have not been
contaminated. Contaminated fluids and lubricants (milky,
foamy in appearance) should be flushed/changed as soon
as possible to prevent component damage.
386 STARTING AND OPERATING

(C) Injecting Tire Service Kit Sealant Into The
Deflated Tire:
•Always start the engine before turning ON the Tire
Service Kit.
NOTE: Manual transmission vehicles must have the park-
ing brake engaged and the gear selector in NEUTRAL.
• After pushing the Power Button (4), the sealant (white
fluid) will flow from the Sealant Bottle (1) through the
Sealant Hose (6) and into the tire.
NOTE: Sealant may leak out through the puncture in the
tire. If the sealant (white fluid) does not flow within0–10
seconds through the Sealant Hose (6):
1. Push the Power Button (4) to turn Off the Tire Service
Kit. Disconnect the Sealant Hose (6) from the valve stem.
Make sure the valve stem is free of debris. Reconnect the
Sealant Hose (6) to the valve stem. Check that the Mode
Select Knob (5) is in the Sealant Mode position and not
Air Mode. Push the Power Button (4) to turn On the Tire
Service Kit.
2. Connect the Power Plug (8) to a different 12 Volt power outlet in your vehicle or another vehicle, if available.
Make sure the engine is running before turning ON the
Tire Service Kit.
3. The Sealant Bottle (1) may be empty due to previous use. Call for assistance.
NOTE: If the Mode Select Knob (5) is on Air Mode and the
pump is operating, air will dispense from the Air Pump
Hose (7) only, not the Sealant Hose (6).

WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” 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.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der 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 prolonged brak-
ing, 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 And Lubricants” in “Technical Specifications”
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.
NOTE: No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.

SERVICING AND MAINTENANCE 479

CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis-
sion Fluid (ATF) is an engineered product and its perfor-
mance may be impaired by supplemental additives. There-
fore, do not add any fluid additives to the transmission.
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 transmission
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 transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit your autho-
rized dealer immediately. Severe transmission damage
may occur. Your authorized dealer has the proper tools
to adjust the fluid level accurately.
