2023 JEEP WAGONEER warning

IN CASE OF EMERGENCY305
To Reset The Manual Park Release:

1. Apply firm pressure to the brake pedal while seated
in the driver’s seat.

2. Pull the tether strap out again, then release it.
3. Allow the tether to retract with the lever back to its original position.
4. Verify that the transmission is in PARK (P).
5. Confirm that the tether has retracted fully and reinstall the access cover. If the access cover cannot
be reinstalled, repeat steps 1 through 4.

Tether Reinstalled

NOTE:When the lever is locked in the released position, the
tether will remain outside of the trim panel and the access
cover cannot be reinstalled.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Push and hold the lock button on the gear
selector. Then, shift back and forth between DRIVE (D) and
REVERSE (R) while gently pressing the accelerator.
NOTE:Shifts between DRIVE (D) and REVERSE (R) can only be
achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL (N) for
more than two seconds, you must press the brake pedal
to engage DRIVE (D) or REVERSE (R).
Use the least amount of accelerator pedal pressure that
will maintain the rocking motion without spinning the
wheels or racing the engine.
NOTE:Push the ESC OFF button to place the Electronic Stability
Control (ESC) system in “Partial OFF” mode, before rocking
the vehicle
Úpage 242. Once the vehicle has been freed,
push the ESC OFF button again to restore “ESC On” mode.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels
faster than 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping when you
are stuck and do not let anyone near a spinning wheel,
no matter what the speed.
CAUTION!
 Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the
engine to idle with the transmission in NEUTRAL for
at least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce the
risk of transmission failure during prolonged efforts
to free a stuck vehicle.
 When “rocking” a stuck vehicle by shifting between
DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
 Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).

316SERVICING AND MAINTENANCE
CHECKING OIL LEVEL — 3.0L ENGINES
The 3.0L engine does not have a traditional “dipstick” and
there is no need to manually check the oil level. If it is
desired to check engine oil level, it can be seen on the
instrument cluster display by navigating to the appropriate
screen under “Vehicle Information”. Use the up or
down arrow buttons within the steering wheel controls
to find the “Vehicle Information” menu. Then use the
right or left arrow buttons until you reach the “Oil
Level” sub-menu.
There is a white bar on the gauge which shows the oil level.
As long as the oil level is between the minimum and the
maximum it is safe to operate the vehicle. If the oil level is
either too high or too low, a red bar will be illuminated.
When the engine is in need of more oil, the Oil Level
Warning Light will illuminate. This warning will appear for
five seconds. Within the next 300 miles (500 km) you
should add 1 quart of manufacturer specified motor oil to
the engine
Úpage 376. This light will reappear every time the engine is started
until a safe level is detected. Continuing to operate the
vehicle without adding oil may result in a critically low oil
level and possible engine damage (see “Critically Low”
below).
NOTE:Use care when filling under hood fluids such as engine oil,
washer fluid, antifreeze, etc. to minimize spillage onto top
of engine. Any excess fluid that is spilled onto the top of
the engine should be removed using compressed air or an
absorbent cloth.
Oil Level Display - How To Refresh After Adding Oil
In vehicles equipped with the 3.0L engine, the oil level is
automatically monitored when the vehicle is parked on a
level surface, the oil is warm, and the engine has been off
four minutes. To refresh the oil level display (after a quart
of the correct oil has been added), follow this process:

Run the engine until the oil temperature is above
120°F (49°C).
 Park the vehicle on relatively level ground. 
Turn the engine off and wait four minutes. If you choose
to stay in the vehicle and want to listen to the radio
while waiting, it is acceptable to have the ignition
switch in any position (OFF or ON/RUN) as long as the
engine is not running.
 Start the engine and the new oil level will be available
in the Vehicle Information menu (accessible via the
navigation buttons on the steering wheel).
NOTE:
If the level indication is not updated after the previously
described procedure, repeat. The oil level measure -
ment is made every time the engine has been turned
off (after being warmed up) and on a level surface. If
you do not get a “new” reading after adding oil, find a
more “level” surface to measure. Most parking lots and
gas stations are sufficiently level, some driveways are
not.
 If you have added a quart of oil and the indicator is not
reading 3/4 or full, please contact an authorized dealer
for service.
Oil Level Critically Low
(Add 2 Quarts)
Oil Level Low (Add 1 Quart)
Oil Level Ok
Oil Level Critically High
WARNING!
Be aware the oil cap may be hot. Please use suitable
gloves. WARNING: risk of burns!
CAUTION!
Do not to add too much oil. Overfilling the oil may
damage the engine.

23_WS_OM_EN_USC_t.book Page 316

SERVICING AND MAINTENANCE317
NOTE:
After adding oil to the engine, always reinstall the oil
cap securely by rotating clockwise until it stops. Never
run the engine without the oil fill cap as this could
cause an oil leak.
 Because the oil level is automatically detected only
when the engine has been off and restarted (after four
minutes), the system cannot immediately detect a
sudden drop in oil level while driving (for example, if the
oil pan starts to leak due to damage during an off-road
event).
CHECKING OIL LEVEL — 5.7L & 6.4L
E
NGINES
To ensure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a fully
warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings.
There are four possible dipstick types:
 Crosshatched zone.
 Crosshatched zone marked SAFE.
 Crosshatched zone marked with MIN at the low end of
the range and MAX at the high end of the range.
 Crosshatched zone marked with dimples at the MIN
and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 qt (1 L) of oil when the reading is at the low end
of the dipstick range will raise the oil level to the high end
of the range marking.
ADDING WASHER FLUID
The instrument cluster display will indicate when the
washer fluid level is low. When the sensor detects a low
fluid level, the Low Washer Fluid Warning Light will turn on
and the "Washer Fluid Low" message will be displayed.
The fluid reservoir for the windshield washers and the rear
window washer is shared. The fluid reservoir is located in
the engine compartment, be sure to check the fluid level
at regular intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze). When
refilling the washer fluid reservoir, take some washer fluid
and apply it to a cloth or towel and wipe clean the wiper
blades, this will help blade performance. To prevent
freeze-up of your windshield washer system in cold
weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
NOTE:Use care when filling under hood fluids such as engine oil,
washer fluid, antifreeze, etc. to minimize spillage onto top
of engine. Any excess fluid that is spilled onto the top of
the engine should be removed using compressed air or an
absorbent cloth.
CAUTION!
If the “Critically Low or Critically High” Oil Level Warning
Light is illuminated, the following steps should be
taken:
Critically Low: add two quarts of manufacturer speci -
fied oil as soon as possible
Úpage 376. Continuing
to operate the vehicle with “Critically Low” oil level
may damage the engine.
 Critically High: contact an authorized dealer for
service. Continuing to operate the vehicle with “Criti -
cally High” oil level may damage the engine.
Do not use any oils that are not manufacturer specified
and API approved.
Used engine oil and oil filters contain substances which
are harmful to the environment. When oil and filters are
changed contact an authorized dealer and dispose of in
a safe and responsible manner.
WARNING!
Commercially available windshield washer solvents are
flammable. They could ignite and burn you. Care must
be exercised when filling or working around the washer
solution.

ENGINE OIL
Engine Oil Selection
Use only the manufacturer's recommended fluids Úpage 376.
NOTE:Hemi engines at times can tick right after startup and then
quiet down after approximately 30 seconds. This is normal
and will not harm the engine. This characteristic can be
caused by short drive cycles. For example, if the vehicle is
started then shut off after driving a short distance. Upon
restarting, you may experience a ticking sound. Other
causes could be if the vehicle is unused for an extended
period of time, incorrect oil, extended oil changes or
extended idling. If the engine continues to tick or if the
Malfunction Indicator Light (MIL) comes on, see the
nearest authorized dealer.
American Petroleum Institute (API)
Approved Engine Oil
