2023 JEEP WRANGLER service

168STARTING AND OPERATING
System Overview
This vehicle is equipped with a Diesel Exhaust Fluid (DEF)
injection system and a Selective Catalytic Reduction (SCR)
catalyst to meet the emission requirements.
The DEF injection system consists of the following
components:
DEF tank
 DEF pump
 DEF injector
 Electronically-heated DEF Lines
 NOx sensors
 Temperature sensors
 SCR catalyst
The DEF injection system and SCR catalyst enable the
achievement of diesel emission requirements; while
maintaining outstanding fuel economy, drivability, torque
and power ratings.
For system messages and warnings see
Úpage 108.
NOTE:
 Your vehicle is equipped with a DEF injection system.
You may occasionally hear an audible clicking noise
from under the vehicle at a stop. This is normal opera -
tion.
 The DEF pump will run for a period of time after engine
shutdown to purge the DEF system. This is normal
operation and may be audible from the rear of the
vehicle.
Diesel Exhaust Fluid Storage
Diesel Exhaust Fluid (DEF) is considered a very stable
product with a long shelf life. If DEF is kept in
temperatures between 10° and 90°F (-12° and 32°C), it
will last a minimum of one year.
DEF is subject to freezing at the lowest temperatures. For
example, DEF 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 DEF, it is important to know that:
Any containers or parts that come into contact with DEF
must be DEF compatible (plastic or stainless steel).
Copper, brass, aluminum, iron or non-stainless steel
should be avoided as they are subject to corrosion by
DEF.
 If DEF is spilled, it should be wiped up completely.
Adding Diesel Exhaust Fluid
The DEF gauge (located on the instrument cluster display)
will display the level of DEF remaining in the tank
Úpage 108.
NOTE:Driving conditions (altitude, vehicle speed, load, etc.) will
affect the amount of DEF that is used in your vehicle.
DEF FILL PROCEDURE
NOTE:
For the correct DEF fluid type see Úpage 374.

1. Remove cap from DEF fill inlet (located in fuel door).

Fuel and Diesel Exhaust Fluid Fill Location

2. Insert DEF fill adapter/nozzle into DEF fill inlet.
NOTE:
 The DEF gauge may take up to five seconds to
update after adding a gallon or more of Diesel
Exhaust Fluid (DEF) to the DEF tank. If you have a
fault related to the DEF system, the gauge may not
update to the new level. See an authorized dealer
for service.
 The DEF gauge may also not immediately update
after a refill if the temperature of the DEF fluid is
below 12°F (-11°C). The DEF tank heater will

STARTING AND OPERATING183
CROSSING DITCHES, STREAMS, SHALLOW
RIVERS OR OTHER FLOWING WATER
Flowing water can be extremely dangerous. Never attempt
to cross a fast running stream or river even in shallow
water. Fast moving water can easily push your vehicle
downstream, sweeping it out of control. Even in very
shallow water, a high current can still wash the dirt out
from around your tires putting you and your vehicle in
jeopardy. There is still a high risk of personal injury and
vehicle damage with slower water currents in depths
greater than the vehicle's running ground clearance. You
should never attempt to cross flowing water which is
deeper than the vehicle's running ground clearance. Even
the slowest current can push the heaviest vehicle
downstream and out of control if the water is deep enough
to push on the large surface area of the vehicle's body.
Before you proceed, determine the speed of the current,
the water's depth, approach angle, bottom condition and
if there are any obstacles. Then cross at an angle heading
slightly upstream using the low and slow technique.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is always
a good idea to check for damage. That way you can get any
problems taken care of right away and have your vehicle
ready when you need it.
Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
 Inspect the radiator for mud and debris and clean as
required.
 Check threaded fasteners for looseness, particularly
on the chassis, drivetrain components, steering, and
suspension. Retighten them, if required, and torque to
the values specified in the Service Manual.
 Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
 After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
NOTE:Inspect the clutch vent holes in the manual transmission
bell housing for mud and debris and clean as required.
If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
WARNING!
Never drive through fast moving deep water. It can push
your vehicle downstream, sweeping it out of control.
This could put you and your passengers at risk of injury
or drowning.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might not
have full braking power when you need it to prevent a
collision. If you have been operating your vehicle in dirty
conditions, get your brakes checked and cleaned as
necessary.

and effective manner.
Do NOT attach any object to the touchscreen. Doing so
can result in damage to the touchscreen.
Please read and follow these safety precautions. Failure to
do so may result in injury or property damage.
Become familiar with the Uconnect features and appli -
cations in this vehicle before you drive on the roadway
so using Uconnect will be more intuitive and will not
require prolonged viewing of the screen while you are
driving.
 When driving, looking at the touchscreen should only
be done by a glance when safe to do so. If prolonged
viewing of the screen is required, choose a safe and
secure location where you can pull over and park safely
to do so. 
Stop use immediately if a problem occurs. Failure to do
so may cause injury or damage to the product. See an
authorized dealer for repair.
 Ensure the volume level of the system is set to a level
that still allows you to hear outside traffic and emer -
gency vehicles.
Safe Usage Of The Uconnect System
 The Uconnect system is a sophisticated electronic
device. Do not let young children use the system.
 Permanent hearing loss may occur if you play your
music or sound system at loud volumes. Exercise
caution when setting the volume on the system.
 Keep drinks, rain and other sources of moisture away
from the system. Besides damage to the system, mois -
ture can cause electric shocks as with any electronic
device.
NOTE:Many features of this system are speed dependent. For
your own safety, it is not possible to use some of the touch -
screen features while the vehicle is in motion.
Care And Maintenance
 Do not press the touchscreen with any hard or sharp
objects (pen, USB stick, jewelry, etc.), which could
scratch the surface.
 Do not spray any liquid or chemicals directly on the
screen! Use a clean and dry microfiber lens cleaning
cloth in order to clean the touchscreen.
 If necessary, use a lint-free cloth dampened with a
cleaning solution, such as isopropyl alcohol or an
isopropyl alcohol and water solution ratio of 50:50. Be
sure to follow the solvent manufacturer's precautions
and directions
Úpage 381.
WARNING!
ALWAYS obey traffic laws and pay attention to the road.
Your complete attention is always required while driving
to maintain safe control of your vehicle. Only use and
interact with the features and applications when it is
safe to do so. Failure to follow these warnings can
result in a collision and death or serious personal
injury.
