check engine light JEEP WRANGLER UNLIMITED 2019 Owner handbook (in English)

ALWAYS DO A VISUAL CHECKthat your vehicle
is in PARK by looking for the "P" in the
instrument cluster display and on the shifter.
As an added precaution, always apply the
parking brake when exiting the vehicle.
Normal Starting — Diesel Engine
1. The gear selector must be in the NEU-
TRAL or PARK position before you can
start the engine.
2. Place the ignition in the ON position.
3. Watch for the “Wait To Start Light” in the
instrument cluster. Refer to “Instrument
Cluster” in “Getting To Know Your Instru-
ment Panel” for further review. It will glow
for two to ten seconds or more, depending
on engine temperature. When the “Wait
To Start Light” goes out, the engine is
ready to start.
4. Tip Start Feature
Do notpress the accelerator. Cycle the
ignition to the START position and then
release it. The starter motor will continue
to run, and it will automatically disengage
when the engine is running. If the engine
fails to start, the starter will disengageautomatically in 25 seconds. If this oc-
curs, cycle the ignition to the LOCK posi-
tion, wait 25 to 30 seconds, then repeat
the “Normal Starting” procedure.
NOTE:
The starter motor may run up to 30 sec-
onds in very cold conditions until the
engine is started. The starter can be dis-
engaged by cycling the ignition to the
OFF position, if required.
5. After the engine starts, allow it to idle for
approximately 30 seconds before driving.
This allows oil to circulate and lubricate
the turbocharger.
Diesel Engine Warm-Up
Avoid full throttle operation when the engine
is cold. When starting a cold engine, bring the
engine up to operating speed slowly to allow
the oil pressure to stabilize as the engine
warms up.NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,200 rpm during the
warm-up period, especially in cold, ambient
temperature conditions.
If temperatures are below 32°F (0°C), oper-
ate the engine at moderate speeds for five
minutes before full loads are applied.
Diesel Engine Idling — In Cold Weather
Avoid prolonged idling in ambient tempera-
tures below 0°F (-18°C). Long periods of
idling may be harmful to your engine because
combustion chamber temperatures can drop
so low that the fuel may not burn completely.
Incomplete combustion allows carbon and
varnish to form on piston rings and injector
nozzles. Also, the unburned fuel can enter
the crankcase, diluting the oil and causing
rapid wear to the engine.

3. At the next vehicle stop (after turning off
the STOP/START system), the engine will
not be stopped.
4. The STOP/START system will reset itself
back to an ON condition every time the
ignition is turned off and back on.
To Manually Turn On The Stop/Start
System
Push the STOP/START OFF switch (located
on the switch bank). The light on the switch
will turn off.
For complete details on the Stop/Start Sys-
tem refer to the “Stop/Start System” in the
“Starting And Operating” section located in
your Owner’s Manual for further information.
System Malfunction
If there is a malfunction in the STOP/START
system, the system will not shut down the
engine. A “SERVICE STOP/START SYSTEM”
message will appear in the instrument cluster
display. Refer to “Instrument Cluster Dis-
play“ in “Getting to Know Your Instrument
Panel” for further information.
If the “SERVICE STOP/START SYSTEM”
message appears in the instrument cluster
display, have the system checked by an au-
thorized dealer.
SPEED CONTROL
When engaged, the Speed Control takes over
accelerator operations at speeds greater than
20 mph (32 km/h).
The Speed Control buttons are located on the
right side of the steering wheel.

“Fluids and lubricants” in the “Technical
specifications” section. The vehicle is
equipped with an automatic AdBlue heating
system when the engine starts allowing the
system to work correctly at temperatures
lower than 12 °F (-11 °C).
NOTE:
AdBlue freezes at temperatures lower than
12 °F (-11 °C).
AdBlue (UREA) Storage
AdBlue (UREA) is considered a very stable
product with a long shelf life. If AdBlue
(UREA) is kept in temperatures between
10° and 90°F (-12° and 32°C), it will last a
minimum of one year.
AdBlue (UREA) is subject to freezing at the
lowest temperatures. For example, AdBlue
(UREA) may freeze at temperatures at or
below 12° F (-11° C). The system has been
designed to operate in this environment.NOTE:
When working with AdBlue (UREA), it is
important to know that:
• Any containers or parts that come into con-
tact with AdBlue (UREA) must be AdBlue
(UREA) compatible (plastic or stainless
steel). Copper, brass, aluminum, iron or
non-stainless steel should be avoided as
they are subject to corrosion by AdBlue
(UREA).
• If AdBlue (UREA) is spilled, it should be
wiped up completely.
Adding AdBlue (UREA)
Preliminary Conditions
AdBlue (UREA) freezes at temperatures
lower than 12° F (-11° C). If the car stands for
a long time at this temperature refilling could
be difficult. For this reason, it is advised to
park the vehicle in a garage and/or heated
environment and wait for the urea to return to
liquid state before topping up.
Proceed as follows:
• Park the car on flat ground and stop the
engine by cycling the ignition to the OFF
position.• Open the fuel door, undo and remove the
cap (blue) from the AdBlue (UREA) filler.
Refilling With Nozzles
You can fill up at any AdBlue (UREA) dis-
tributor.
Proceed as follows:
• Insert the AdBlue (UREA) nozzle in the
filler, start refilling and stop refilling at the
first shut-off (the shut-off indicates that the
AdBlue (UREA) tank is full). Do not pro-
ceed with the refilling, to prevent spillage
of AdBlue (UREA).
• Extract the nozzle.
Refilling With Containers
Proceed as follows:
• Check the expiration date.
• Read the advice for use on the label before
pouring the content of the bottle into the
AdBlue (UREA) tank.
• If systems which cannot be screwed in (e.g.
tanks) are used for refilling, after the indi-
cation appears on the instrument panel
display refer to “Warning lights And Mes-
sages" in the “Getting To Know Your Instru-
169

Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change.
Once A Month Or Before A Long Trip
• Check the engine oil level about five min-
utes after a fully warmed engine is shut off.
Checking the oil level while the vehicle is
on level ground will improve the accuracy of
the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.• Inspect the battery and clean and tighten
the terminals as required.
• Check the fluid levels of coolant reservoir,
brake master cylinder and power steering
and fill as needed.
• Check all lights and other electrical items
for correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.Required Maintenance Intervals
Refer to the Maintenance Plan on the follow-
ing pages for the required maintenance inter-
vals.
Maintenance Plan
NOTE:
Once you have carried out the last interven-
tion in the table, continue with the scheduled
servicing, maintaining the frequency indi-
cated in the plan by marking each operation
with a dot or dedicated note. Simply restart-
ing the maintenance from the start of the
plan may cause the allowed interval to be
exceeded for some operations.

•The timing and accessory belts must be
changed every 37,500 miles (60,000 km) or
3 years for particularly demanding use (dusty
areas, severe weather conditions, very low or
very high temperatures for extended periods,
city driving, long periods of idling). Under no
circumstances should these intervals be
exceeded.
Once A Month Or Before A Long Trip
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.
• Check the fluid levels of the coolant reser-
voir and brake master cylinder, fill as
needed.
• Check function of all interior and exterior
lights.
• Control and recovery of additive level for
AdBlue Diesel emissions (UREA) (if
equipped).Demanding Vehicle Use
• Restore additive level for AdBlue Diesel
emissions (UREA) (if equipped), when the
lamp is illuminated or the message on the
instrument panel.
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.
