2019 JEEP WRANGLER UNLIMITED washer fluid

Windshield Wiper Operation
Rotate the end of the lever upward to the
second detent past the intermittent settings
for low-speed wiper operation. Rotate the end
of the lever upward to the third detent past
the intermittent settings for high-speed wiper
operation.
CAUTION!
In cold weather, always turn off the wiper
switch and allow the wipers to return to the
park position before turning off the en-
gine. If the wiper switch is left on and the
wipers freeze to the windshield, damage to
the wiper motor may occur when the ve-
hicle is restarted.
NOTE:
Do not operate the windshield wipers with the
blades lifted from the windshield.
Intermittent Wiper System
Use the intermittent wiper when weather
conditions make a single wiping cycle, with a
variable pause between cycles, desirable. Ro-tate the end of the lever to the first detent
position for one of four intermittent settings.
The delay cycle can be set anywhere between
1 to 18 seconds.
NOTE:
The wiper delay times depend on vehicle
speed. If the vehicle is moving less than
10 mph (16 km/h), delay times will be
doubled.
Windshield Washers
To use the washer, pull the lever toward you
and hold while spray is desired. If the lever is
pulled while in the delay range, the wiper will
start and continue to operate for two or three
wipe cycles after the lever is released. Then,
the intermittent interval previously selected
will resume.
If the lever is pulled while in the off position,
the wipers will operate for two or three wipe
cycles. Then, the wipers will turn off.
WARNING!
Sudden loss of visibility through the wind-
shield could lead to a collision. You might
WARNING!
not see other vehicles or other obstacles.
To avoid sudden icing of the windshield
during freezing weather, warm the wind-
shield with the defroster before and during
windshield washer use.
Mist Feature
Push upward on the wiper lever to activate a
single wipe to clear off road mist or spray
from a passing vehicle. As long as the lever is
held up, the wipers will continue to operate.
NOTE:
The mist feature does not activate the washer
pump; therefore, no washer fluid will be
sprayed on the windshield. The wash func-
tion must be used in order to spray the
windshield with washer fluid.
Rear Window Wiper/Washer — If Equipped
A rotary switch on the center portion of the
windshield wiper/washer lever controls the
operation of the rear wiper/washer function.

• The ESC system will make buzzing or click-
ing sounds when it is active. This is normal;
the sounds will stop when ESC becomes
inactive.
• This light will come on when the vehicle is
in an ESC event.
— Electronic Stability Control (ESC) Off
Warning Light — If Equipped
This warning light indicates the Electronic
Stability Control (ESC) is off.
Each time the ignition is turned to ON/RUN
or ACC/ON/RUN, the ESC system will be on,
even if it was turned off previously.
— Loose Fuel Filler Cap Warning Light
— If Equipped
This warning light will illuminate when the
fuel filler cap is loose. Properly close the filler
cap to disengage the light. If the light does
not turn off, please see an authorized dealer.
— Low Fuel Warning Light
When the fuel level reaches approximately
2.0 gal (7.5 L), this light will turn on and a
chime will sound. The light will remain on
until fuel is added.
— Low Washer Fluid Warning Light —
If Equipped
This warning light will illuminate when the
windshield washer fluid is low.
— Engine Check/Malfunction Indica-
tor Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine
and automatic transmission control systems.
This warning light will illuminate when the
ignition is in the ON/RUN position before
engine start. If the bulb does not come on
when turning the ignition switch from OFF to
ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicleshould be serviced if the light stays on
through several typical driving styles. In most
situations, the vehicle will drive normally and
will not require towing.
When the engine is running, the MIL may
flash to alert serious conditions that could
lead to immediate loss of power or severe
catalytic converter damage. The vehicle
should be serviced by an authorized dealer as
soon as possible if this occurs.
WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.
This could result in death or serious injury
to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-

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

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.

• 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
