2019 JEEP CHEROKEE Engine light

The engine oil installed in the engine at the
factory is a high-quality energy conserving
type lubricant. Oil changes should be consis-
tent with anticipated climate conditions un-
der which vehicle operations will occur.
For the recommended viscosity and quality
grades, refer to “Fluids And Lubricants” in
“Technical Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.
NOTE:
A new engine may consume some oil during
its first few thousand miles (kilometers) of
operation. This should be considered a nor-
mal part of the break-in and not interpreted
as a problem.
PARKING BRAKE
Electric Park Brake (EPB)
Your vehicle is equipped with a new Electric
Park Brake System (EPB) that offers greater
convenience. The park brake switch is lo-
cated in the center console.
To apply the park brake manually, pull up on
the switch momentarily. The BRAKE telltale
light in the instrument cluster and an indica-
tor on the switch will illuminate.To release the park brake manually, the igni-
tion must be in ON/RUN. Then put your foot
on the brake pedal and push the park brake
switch down momentarily. Once the park
brake is fully disengaged, the BRAKE telltale
light and the switch indicator will extinguish.
The park brake can also be automatically
released. With the engine running and the
transmission in gear, release the brake pedal
and depress the throttle pedal. For safety
reasons, your seat belt must also be fastened.
NOTE:
• You may hear a slight whirring sound from
the back of the vehicle while the parking
brake engages or disengages.
• If your foot is on the brake pedal while you
are engaging or disengaging the parking
brake, you may notice a small amount of
brake pedal movement.
• The new Auto Park Brake feature can be
used to apply the park brake automatically
every time you park the vehicle. Auto Park
Brake can be enabled and disabled in the
Settings menu in Uconnect.

Shift Positions
For additional information on the appropriate
use of each 4WD system mode position, see
the information below:
NEUTRAL
This range disengages the driveline from the
powertrain.
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
power transfer unit in the NEUTRAL (N)
position without first fully engaging the
parking brake. The NEUTRAL (N) position
disengages both the front and rear drive-
shafts from the powertrain and will allow
the vehicle to roll, even if the automatic
transmission is in PARK (or manual trans-
mission is in gear). The parking brake
should always be applied when the driver
is not in the vehicle.
4WD LOW
This range is for low speed four-wheel drive.
It provides an additional gear reduction
which allows for increased torque to be deliv-
ered to both the front and rear wheels while
providing maximum pulling power for loose,
slippery road surfaces only. Do not exceed
25 mph (40 km/h).
NOTE:
Refer to “Selec-Terrain — If Equipped” for
further information on the various positions
and their intended usages.
Shifting Procedures
Shifting Into 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition in the ON mode and the
engine running, shift the transmission into
NEUTRAL, and push the “4WD LOW” button
once. The “4WD LOW” indicator light in the
instrument cluster will begin to flash and
remain on solid when the shift is complete.NOTE:
If shift conditions/interlocks are not met, a
message will flash from the instrument clus-
ter display with instructions on how to com-
plete the requested shift.
Refer to “Instrument Cluster Display” in
“Getting To know Your Instrument Panel” for
further information.

Shifting Out Of 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition in the ON mode and the
engine running, shift the transmission into
NEUTRAL, and push the “4WD LOW” button
once. The “4WD LOW” indicator light in the
instrument cluster will flash and go out when
the shift is complete.

message will flash from the instrument
cluster display with instructions on how to
complete the requested shift. Refer to “In-
strument Cluster Display” in “Getting To
Know Your Instrument Panel” for further
information.
• Shifting into or out of 4WD LOW is possible
with the vehicle completely stopped; how-
ever, difficulty may occur due to the mating
clutch teeth not being properly aligned.
Several attempts may be required for
clutch teeth alignment and shift comple-
tion to occur. The preferred method is with
the vehicle rolling 0 to 3 mph (0 to 5 km/h).If the vehicle is moving faster than 3 mph
(5 km/h), the 4WD system will not allow the
shift.
NEUTRAL Shift Procedure
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
power transfer unit in the NEUTRAL (N)
position without first fully engaging the
parking brake. The NEUTRAL (N) position
disengages both the front and rear drive-
shafts from the powertrain and will allow
the vehicle to roll, even if the automatic
transmission is in PARK (or manual trans-
mission is in gear). The parking brake
should always be applied when the driver
is not in the vehicle.
1. Bring the vehicle to a complete stop on
level ground and shift the automatic
transmission to PARK
2. Turn the engine OFF.
