2023 JEEP WAGONEER fuel

136STARTING AND OPERATING
NOTE:
Even if the power steering assistance is no longer oper -
ational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
 If the condition persists, see an authorized dealer for
service.
If the Steering icon is displayed and the “POWER
STEERING SYSTEM OVER TEMP” message is displayed on
the instrument cluster screen, they indicate that extreme
steering maneuvers may have occurred which caused an
over temperature condition in the electric power steering
system. Once driving conditions are safe, pull over and let
the vehicle idle for a few moments until the icon and
message turn off.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to reduce fuel
consumption. The system will stop the engine
automatically during a vehicle stop if the required
conditions are met. Releasing the brake pedal or pressing
the accelerator pedal will automatically restart the engine
Úpage 136.
This vehicle has been upgraded with a heavy-duty starter,
enhanced battery, and other upgraded engine parts, to
handle the additional engine starts.
AUTOSTOP MODE
The Stop/Start feature is enabled after every normal
customer engine start. At that time, the system will go into
STOP/START READY and if all other conditions are met,
can go into a STOP/START AUTOSTOP ACTIVE Autostop
mode.
To Activate The Autostop Mode, The Following Must Occur:
 The system must be in STOP/START READY state. A
“STOP/START READY” message will be displayed in the
instrument cluster display within the Stop/Start
section
Úpage 99.
 The vehicle must be completely stopped.
 The gear selector must be in a forward gear and the
brake pedal pressed.
The engine will shut down, the tachometer will move to the
zero position, and the Stop/Start telltale will illuminate
indicating you are in Autostop. Customer settings will be
maintained upon return to an engine-running condition.
POSSIBLE REASONS THE ENGINE DOES
N
OT AUTOSTOP
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
Detailed information about the operation of the Stop/Start
system may be viewed in the instrument cluster display
Stop/Start Screen. In the following situations, the engine
will not stop:
 Driver’s seat belt is not buckled.
 Driver’s door is not closed.
 Battery temperature is too warm or cold.
 Battery charge is low. 
The vehicle is on a steep grade.
 Cabin heating or cooling is in process and an accept -
able cabin temperature has not been achieved.
 HVAC is set to full defrost mode at a high blower speed.
 HVAC is set to MAX A/C.
 Engine has not reached normal operating temperature.
 The transmission is not in a forward gear.
 Hood is open.
 Vehicle is in 4WD LOW, or an off-road
Selec-Terrain mode.
 Brake pedal is not pressed with sufficient pressure.
 Accelerator pedal input.
 Engine temperature is too high.
 5 mph (8 km/h) threshold has not been achieved from
previous Autostop.
 Steering angle is beyond threshold.
It may be possible for the vehicle to be driven several
times without the Stop/Start system going into a
STOP/START READY state under more extreme conditions
of the items listed above.
TO START THE ENGINE WHILE IN
A
UTOSTOP MODE
While in a forward gear, the engine will start when the
brake pedal is released or the throttle pedal is pressed.
The transmission will automatically re-engage upon
engine restart.

STARTING AND OPERATING177
If the vehicle is in PARK, Zoom View is available until the
gear selector is placed in DRIVE or REVERSE and speeds
are at or above 8 mph (13 km/h).
NOTE:
If the vehicle is in DRIVE, NEUTRAL, or REVERSE, and
speed is greater than or equal to 8 mph (13 km/h),
Zoom View is unavailable and the icon will appear gray.
 While in Zoom View, the guidelines will not be visible.
REFUELING THE VEHICLE

1. Open the fuel filler door by pushing on the outer
edge of the fuel door near the center to unlatch.
Then use a finger to rotate the door to the full open
position.

Fuel Filler Door

NOTE:
In certain cold conditions, ice may prevent the fuel
door from opening. If this occurs, lightly push
around the perimeter of the fuel door to break the
ice buildup.
 There is no fuel filler cap. Two flapper doors inside
the pipe seal the system.
2. Insert the fuel nozzle fully into the filler pipe – the nozzle opens and holds the flapper doors while
refueling.
NOTE:Only the correct size nozzle opens the latches allowing the
flapper doors to open.

Fuel Filler

3. Fill the vehicle with fuel – when the fuel nozzle “clicks” or shuts off the fuel tank is full. 4. Wait five seconds before removing the fuel nozzle to
allow fuel to drain from nozzle.
5. Remove the fuel nozzle and close the fuel door. Engage the fuel door latch by pushing on the outer
edge near the center.
NOTE:For further information on fuel requirements see Úpage 372.
WARNING!
Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
 Never add fuel when the engine is running. This is in
violation of most state and federal fire regulations
and may cause the Malfunction Indicator Light to
turn on.
 A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not “top off” the
fuel tank after filling.

178STARTING AND OPERATING
VEHICLE LOADING
GROSS VEHICLE WEIGHT RATING
(GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR.
PAYLOAD
The payload of a vehicle is defined as the allowable weight
a vehicle can carry, including the weight of the driver, all
passengers, options and cargo.
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles, or suspension
components sometimes specified by purchasers for
increased durability, do not necessarily increase the
vehicle's GVWR or GAWR.
TIRE SIZE
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
RIM SIZE
This is the rim size that is appropriate for the tire size
listed.
INFLATION PRESSURE
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
CURB WEIGHT
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
LOADING
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to ensure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should then
be determined separately to be sure that the load is
properly distributed over the front and rear axles.
Weighing the vehicle may show that the GAWR of either
the front or rear axles has been exceeded but the total
load is within the specified GVWR. If so, weight must be shifted from front to rear or rear to
front as appropriate until the specified weight limitations
are met. Store the heavier items down low and be sure
that the weight is distributed equally. Stow all loose items
securely before driving.
NOTE:

Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles and
the way the brakes operate.
 Air suspension vehicle may limit off-road heights if
loaded beyond recommended values for vehicle GVWR
and GAWR.
TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with your
vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
WARNING!
Do not load your vehicle any heavier than the GVWR or
the maximum front and rear GAWR. If you do, parts on
your vehicle can break, or it can change the way your
vehicle handles. This could cause you to lose control.
Overloading can shorten the life of your vehicle.

STARTING AND OPERATING189

Seven-Pin Connector

TOWING TIPS
Before towing, practice turning, stopping, and backing up
the trailer in an area located away from heavy traffic. If
equipped with Quadra-Lift air suspension, the automatic
Entry/Exit feature may be disabled through the Uconnect
Touchscreen Radio to prevent vehicle and trailer
movement when gear selector is moved to PARK.
Automatic Transmission
Select the DRIVE (D) range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. However, if frequent shifting does occur
while in DRIVE, you can use the Electronic Range Select
(ERS) shift control to manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle under heavy
loading conditions, will improve performance and extend
transmission life by reducing excessive shifting and heat
build-up. This action will also provide better engine
braking.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
 When using the Cruise Control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
 Use Cruise Control in flat terrain and with light loads to
maximize fuel efficiency.

STARTING AND OPERATING195
If you stall or begin to lose forward motion while climbing
a steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine, and
shift into REVERSE (R). Back slowly down the hill, allowing
the compression braking of the engine to help regulate
your speed. If the brakes are required to control vehicle
speed, apply them lightly and avoid locking or skidding the
tires.
Remember, never drive diagonally across a hill. Always
drive straight up or down.
If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain forward motion
by turning the front wheels slowly. This may provide a fresh
“bite” into the surface and will usually provide traction to
complete the climb.Traction Downhill
When descending mountains or hills, use Hill Descent
Control or Selec-Speed Control to avoid repeated heavy
braking.
If not equipped with Hill Descent Control or Selec-Speed
Control use the following procedure:
Shift the transmission into a low gear, and the transfer
case into 4WD LOW range. Let the vehicle go slowly down
the hill with all four wheels turning against engine
compression drag. This will permit you to control the
vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmission
whenever possible.
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.
 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!
If the engine stalls, you lose forward motion, or cannot
make it to the top of a steep hill or grade, never attempt
to turn around. To do so may result in tipping and rolling
the vehicle. Always back carefully straight down a hill in
REVERSE gear. Never back down a hill in NEUTRAL
using only the brake.
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.

SAFETY253
(Continued)
For information on how to properly inflate the vehicle’s
tires, see
Úpage 349.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low pressure warning
threshold for any reason, including low temperature
effects, or natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above recommended cold
tire pressure. Once the low tire pressure warning has been
illuminated, the tire pressure must be increased to the
recommended cold tire pressure in order for the TPMS
Warning Light to be turned off.
NOTE:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
The system will automatically update and the TPMS
Warning Light will extinguish once the updated tire
pressures have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h) to
receive this information. For example, your vehicle has a recommended cold
(parked for more than three hours) tire pressure of 33 psi
(227 kPa). If the ambient temperature is 68°F (20°C) and
the measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 24 psi (165 kPa). This tire
pressure is sufficiently low enough to turn on the TPMS
Warning Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa), but the
TPMS Warning Light will still be on. In this situation, the
TPMS Warning Light will turn off only after the tires have
been inflated to the vehicle’s recommended cold tire
pressure value.NOTE:

The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire failure
or condition.
 The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
 Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla -
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
 The TPMS is not a substitute for proper tire mainte -
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if underinflation has not reached the level to trigger illu -
mination of the TPMS Warning Light.
 Seasonal temperature changes will affect tire pres -
sure, and the TPMS will monitor the actual tire pres -
sure in the tire.
CAUTION!
 The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warn -
ings have been established for the tire size equipped
on your vehicle. Undesirable system operation or
sensor damage may result when using replacement
equipment that is not of the same size, type, and/or
style. The TPMS sensor is not designed for use on
aftermarket wheels and may contribute to a poor
overall system performance or sensor damage.
Customers are encouraged to use Original Equip -
ment Manufacturer (OEM) wheels to ensure proper
TPMS feature operation.
 Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealership to have your sensor func -
tion checked.
 After inspecting or adjusting the tire pressure, always
reinstall the valve stem cap. This will prevent mois -
ture and dirt from entering the valve stem, which
could damage the Tire Pressure Monitoring System
sensor.
CAUTION!

SAFETY273
If A Deployment Occurs
The front air bags are designed to deflate immediately
after deployment.
NOTE:Front and/or side air bags will not deploy in all collisions.
This does not mean something is wrong with the air bag
system.
If you do have a collision which deploys the air bags, any
or all of the following may occur:
The air bag material may sometimes cause abrasions
and/or skin reddening to the occupants as the air bags
deploy and unfold. The abrasions are similar to friction
rope burns or those you might get sliding along a carpet
or gymnasium floor. They are not caused by contact
with chemicals. They are not permanent and normally
heal quickly. However, if you haven’t healed signifi -
cantly within a few days, or if you have any blistering,
see your doctor immediately.
 As the air bags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for air
bag inflation. These airborne particles may irritate the
skin, eyes, nose, or throat. If you have skin or eye irrita -
tion, rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles settle on your
clothing, follow the garment manufacturer’s instruc -
tions for cleaning. Do not drive your vehicle after the air bags have deployed.
If you are involved in another collision, the air bags will not
be in place to protect you.
NOTE:

Air bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
 After any collision, the vehicle should be taken to an
authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the Occupant Restraint
Controller (ORC) will determine whether to have the
Enhanced Accident Response System perform the
following functions:
Cut off fuel to the engine (if equipped)
 Cut off battery power to the electric motor (if equipped)
 Flash hazard lights as long as the battery has power
 Turn on the interior lights, which remain on as long as
the battery has power or for 15 minutes from the inter -
vention of the Enhanced Accident Response System
 Unlock the power door locks Your vehicle may also be designed to perform any of these
other functions in response to the Enhanced Accident
Response System:

Turn off the Fuel Filter Heater, Turn off the HVAC Blower
Motor, Close the HVAC Circulation Door
 Cut off battery power to the:
 Engine
 Electric Motor (if equipped)
 Electric power steering
 Brake booster
 Electric park brake
 Automatic transmission gear selector
 Horn
 Front wiper
 Headlight washer pump (if equipped)
NOTE:After an accident, remember to cycle the ignition to the
STOP (OFF/LOCK) position and remove the key from the
ignition switch to avoid draining the battery. Carefully
check the vehicle for fuel leaks in the engine compartment
and on the ground near the engine compartment and fuel
tank before resetting the system and starting the engine.
If there are no fuel leaks or damage to the vehicle elec -
trical devices (e.g. headlights) after an accident, reset the
system by following the procedure described below. If you
have any doubt, contact an authorized dealer.
WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags, seat
belt pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer
immediately. Also, have the Occupant Restraint
Controller System serviced as well.

Enhanced Accident Response System
Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition OFF.
Carefully check the vehicle for fuel leaks in the engine
compartment and on the ground near the engine
compartment and fuel tank before resetting the system
and starting the engine.
After an accident, if the vehicle will not start after
performing the reset procedure, the vehicle must be
towed to an authorized dealer to be inspected and to have
the Enhanced Accident Response System reset.
Maintaining Your Air Bag System Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in certain
crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems performed. The
EDR is designed to record data related to vehicle
dynamics and safety systems for a short period of time,
typically 30 seconds or less. The EDR in this vehicle is
designed to record such data as:
How various systems in your vehicle were operating;
 Whether or not the driver and passenger safety belts
were buckled/fastened;
 How far (if at all) the driver was depressing the acceler -
ator and/or brake pedal; and,
 How fast the vehicle was traveling.
These data can help provide a better understanding of the
circumstances in which crashes and injuries occur.WARNING!
 Modifications to any part of the air bag system could
cause it to fail when you need it. You could be injured
if the air bag system is not there to protect you. Do
not modify the components or wiring, including
adding any kind of badges or stickers to the steering
wheel hub trim cover or the upper passenger side of
the instrument panel. Do not modify the front
fascia/bumper, vehicle body structure, or add after -
market side steps or running boards.
 It is dangerous to try to repair any part of the air bag
system yourself. Be sure to tell anyone who works on
your vehicle that it has an air bag system.
 Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may
not function properly if modifications are made. Take
your vehicle to an authorized dealer for any air bag
system service. If your seat, including your trim cover
and cushion, needs to be serviced in any way
(including removal or loosening/tightening of seat
attachment bolts), take the vehicle to an authorized
dealer. Only manufacturer approved seat accesso -
ries may be used. If it is necessary to modify the air
bag system for persons with disabilities, contact an
authorized dealer.
