2018 JEEP GRAND CHEROKEE oil temperature

— Liftgate Open Warning Light
This indicator light will illuminate when the
liftgate is open.
NOTE:
If the vehicle is moving, there will also be a
single chime.
— Oil Pressure Warning Light
This warning light will illuminate to indicate
low engine oil pressure. If the light turns on
while driving, stop the vehicle and shut off
the engine as soon as possible. A chime will
sound when this light turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how
much oil is in the engine. The engine oil level
must be checked under the hood.
— Oil Temperature Warning Light
This telltale indicates engine oil temperature
is high. If the light turns on while driving,
stop the vehicle and shut off the engine as
soon as possible. Wait for oil temperature to
return to normal levels.
— Seat Belt Reminder Warning Light
This light indicates when the driver or pas-
senger seat belt is unbuckled. When the
ignition is first placed in the ON/RUN or
ACC/ON/RUN position and if the driver’s seat
belt is unbuckled, a chime will sound and the
light will turn on. When driving, if the driver
or front passenger seat belt remains unbuck-
led, the Seat Belt Reminder Light will flash or
remain on continuously and a chime will
sound. Refer to “Occupant Restraint Sys-
tems” in “Safety” for further information.
— Transmission Temperature Warning
Light — If Equipped
This light indicates high transmission fluid
temperature. This may occur with strenuous
usage such as trailer towing. If this light turns
on, stop the vehicle and run the engine at idle
or slightly faster, with the transmission in
PARK or NEUTRAL, until the light turns off.
Once the light turns off, you may continue to
drive normally.
WARNING!
If you continue operating the vehicle when
the Transmission Temperature Warning
Light is illuminated you could cause the
fluid to boil over, come in contact with hot
engine or exhaust components and cause a
fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated
will eventually cause severe transmission
damage or transmission failure.
— Vehicle Security Warning Light — If
Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.

WARNING!
• You can be badly injured working on or
around a motor vehicle. Do only service
work for which you have the knowledge
and the right equipment. If you have any
doubt about your ability to perform a
service job, take your vehicle to a com-
petent mechanic.
• Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an
accident.
Severe Duty Conditions
†† Change the engine oil and engine oil filter
at every 3,000 miles (5 000 km) or 3 months
if using your vehicle under any of the follow-
ing severe duty conditions:
• Stop and go driving.
• Driving in dusty conditions.
• Short trips of less than 10 miles (16 km).
• Trailer towing.• Taxi, police, or delivery service (commercial
service).
• Off-road or desert operation.
Scheduled Servicing — Diesel Engine
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for scheduled
servicing.
Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence
when the “Oil Change Required” message is
displayed.
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change. If a scheduled oil
change is performed by someone other than
your authorized dealer, the message can bereset by referring to the steps described un-
der “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for further
information.
Engine Oil Filter Replacement
Residual oil in the housing may spill from the
housing when the new filter is installed if the
residual oil is not either removed from the
housing or enough time has not elapsed to
allow the oil to drain back into the engine.
When servicing the oil filter on this engine,
carefully remove the filter and use a suction
gun to remove any residual oil left in the
housing or wait about 30 minutes for the oil
to drain back into the engine.
To help you have the best driving experience
possible, the manufacturer has identified the
specific vehicle maintenance service inter-
vals that are required to keep your vehicle
operating properly and safely.
The manufacturer recommends that these
maintenance intervals be performed at your
selling dealer. The technicians at your deal-
ership know your vehicle best, and have ac-
cess to factory trained information, genuine
Mopar parts, and specially designed elec-
SERVICING AND MAINTENANCE
238

Checking Oil Level — Gasoline Engine
To assure proper lubrication of your vehicle’s
engine, 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. Always maintain the oil level
within the SAFE zone on the dipstick. Adding
one quart of oil when the reading is at the
bottom of the SAFE zone will result in a
reading at the top of the safe zone on these
engines.
CAUTION!
Overfilling or underfilling the crankcase
will cause aeration or loss of oil pressure.
This could damage your engine.
Checking Oil Level — 3.0 Diesel Engine
To assure proper lubrication of your vehicle's
engine, the engine oil must be maintained at
the correct level. Check the oil level at regular
intervals. The best time to check the oil level
is before starting the engine after it has been
parked overnight. When checking oil after
operating the engine, first ensure the engine
is at full operating temperature, then wait for
five minutes after engine shutdown to check
the oil.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil
level readings. Add oil only when the level on
the dipstick is below the “MIN” mark. The
total capacity from the MIN mark to the MAX
mark is 1 qt (1 L).
CAUTION!
Overfilling or underfilling the crankcase
will cause oil aeration or loss of oil pres-
sure. This could damage your engine.NOTE:
It is possible for your oil level to be slightly
higher than a previous check. This would be
due to diesel fuel that may temporarily be in
the crankcase due to operation of the diesel
particulate filter regeneration strategy. This
fuel will evaporate out under normal opera-
tion.
Never operate the engine with oil level below
the “MIN” mark or above the upper “MAX”
mark.
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 wind-
shield will light on the vehicle graphic outline
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 com-
partment, be sure to check the fluid level at
regular intervals. Fill the reservoir with wind-
shield washer solvent only (not radiator anti-
freeze). When refilling the washer fluid reser-

NOTE:
The wheel articulation will be represented by
a yellow color in the Suspension Articulation
Indicator. If Ride Height is adjusted, the Ride
Height indicator on the screen will switch to
the appropriate height and the Suspension
Articulation Indicator will show the move-
ment and change in height.Pitch And Roll — If Equipped
The Pitch And Roll page displays the vehi-
cle’s current pitch (angle up and down) and
roll (angle side to side) in degrees. The pitch
and roll gauges provide a visualization of the
current vehicle angle.
Accessory Gauges
The Accessory Gauges page displays the cur-
rent status of the vehicle’s Coolant Tempera-
ture, Oil Temperature, Oil Pressure (Gas Ve-
hicles Only), Transmission Temperature, and
Battery Voltage.
