2023 JEEP WRANGLER air condition

132STARTING AND OPERATING
STOPPING THE ENGINE
After full load operation, idle the engine for a few minutes before shutting it down. This idle period will allow the lubricating oil and coolant to carry excess heat away from the
turbocharger.
NOTE:Refer to the following chart for proper engine shutdown.
NOTE:Under certain conditions the engine fan will run after the
engine is turned off. These conditions are under high load
and high temperature conditions.
COOLING SYSTEM TIPS — AUTOMATIC
T
RANSMISSION
To reduce the potential for engine and transmission
overheating in high ambient temperature conditions, take
the following actions:
 City Driving — When stopped, shift the transmission
into NEUTRAL (N) and increase engine idle speed.
 Highway Driving — Reduce your speed. 
Up Steep Hills — Select a lower transmission gear.
 Air Conditioning — Turn it off temporarily.
NOTE:If the coolant temperature is too high, the A/C will auto -
matically turn off.
Do Not Operate The Engine With Low Oil
Pressure
If the Oil Pressure Warning Light turns on while driving,
stop the vehicle and shut down the engine as soon as
possible. A chime will sound when the light turns on. After
the vehicle is safely stopped, restart the engine and
monitor the Oil Pressure Warning Light. If the Oil Pressure
Warning Light is still illuminated, turn the engine OFF and contact an authorized dealer for further assistance. If the
lamp is no longer illuminated, the engine can be operated
but it is recommended to take the vehicle to an authorized
dealer as soon as possible.
NOTE:Do not operate the vehicle until the cause is corrected.
This light does not show how much oil is in the engine. The
engine oil level must be checked under the hood.
Driving Condition Load Turbocharger Temperature Idle Time (min.) Before Engine Shutdown

182STARTING AND OPERATING
DRIVING ACROSS AN INCLINE
If at all possible, avoid driving across an incline. If it is
necessary, know your vehicle's abilities. Driving across an
incline places more weight on the downhill wheels, which
increases the possibilities of a downhill slide or rollover.
Make sure the surface has good traction with firm and
stable soils. If possible, transverse the incline at an angle
heading slightly up or down.
IF YOU STALL OR BEGIN TO LOSE HEADWAY
If you stall or begin to lose headway while climbing a steep
hill, allow your vehicle to come to a stop and immediately
apply the brake. Restart the engine and shift into
REVERSE. Back slowly down the hill allowing engine
braking to control the descent and apply your brakes, if
necessary, but do not allow the tires to lock.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided, if possible, and only
be attempted when necessary in a safe, responsible
manner. Only drive through areas which are designated
and approved. Tread lightly and avoid damage to the
environment. Know your vehicle's abilities and be able to
recover it if something goes wrong. Never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls, do not
attempt to restart it. Determine if it has ingested water
first. The key to any crossing is low and slow. Shift into
FIRST gear (manual transmission), or DRIVE (automatic
transmission), with the transfer case in the 4L position
and proceed very slowly with a constant slow speed of {3
to 5 mph (5 to 8 km/h) maximum} and light throttle. Keep
the vehicle moving; do not try to accelerate through the
crossing. After crossing any water higher than the bottom
of the axle differentials, inspect all of the vehicle fluids for
signs of water ingestion.
BEFORE YOU CROSS ANY TYPE OF WATER
As you approach any type of water, you need to determine
if you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a stick. You
need to be sure of its depth, approach angle, current and
bottom condition. Be careful of murky or muddy waters;
check for hidden obstacles. Make sure you will not be
intruding on any wildlife, and you can recover the vehicle
if necessary. The key to a safe crossing is the water depth,
current and bottom conditions. On soft bottoms, the
vehicle will sink in, effectively increasing the water level on
the vehicle. Be sure to consider this when determining the
depth and the ability to safely cross.
CROSSING PUDDLES, POOLS, FLOODED
AREAS OR OTHER STANDING WATER
Puddles, pools, flooded or other standing water areas
normally contain murky or muddy waters. These water
types normally contain hidden obstacles and make it
difficult to determine an accurate water depth, approach
angle, and bottom condition. Murky or muddy water holes
are where you want to hook up tow straps prior to entering.
This makes for a faster, cleaner and easier vehicle
recovery. If you are able to determine you can safely cross,
than proceed using the low and slow method.
WARNING!
Driving across an incline increases the risk of a rollover,
which may result in severe injury.
WARNING!
If the engine stalls or you lose headway 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, which may result in severe injury. Always
back carefully straight down a hill in REVERSE. Never
back down a hill in NEUTRAL using only the vehicle
brakes. Never drive diagonally across a hill, always drive
straight up or down.
CAUTION!
Water ingestion into the axles, transmission, transfer
case, engine or vehicle interior can occur if you drive
too fast or through too deep of water. Water can
cause permanent damage to engine, driveline or
other vehicle components, and your brakes will be
less effective once wet and/or muddy.
 When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering
as a precaution, and check all fluids afterward.
Driving through water may cause damage that may
not be covered by the New Vehicle Limited Warranty.
CAUTION!
Muddy waters can reduce the cooling system
effectiveness by depositing debris onto the radiator.

SOS Call System Limitations
Vehicles that have been purchased in the US and that
travel into Mexico and Canada may have limited services.
In particular, responses to SOS calls or other emergency
services may be unavailable or very limited. Vehicles
purchased outside the United States and Canada are
unable to receive SiriusXM Guardian™ connected
services.
If the SOS Call system detects a malfunction, any of the
following may occur at the time the malfunction is
detected:
The light will continuously be illuminated red.
 The screen will display the following message “Vehicle
phone requires service. Please contact your dealer.”
 An in-vehicle audio message will state “Vehicle phone
requires service. Please contact your dealer.”
Even if the SOS Call system is fully functional, factors
beyond FCA US LLC’s control may prevent or stop SOS Call
system operation. These include, but are not limited to,
the following factors:
 The ignition key is in OFF position.
 The vehicle’s electrical systems are not intact. 
The vehicle battery loses power or becomes discon -
nected during a vehicle crash.
 The SOS Call system software and/or hardware is
damaged during a vehicle crash.
 LTE (voice/data) or 4G (data) coverage and/or GPS
signals are unavailable or obstructed.
 Network congestion.
 Weather conditions.
 Buildings, structures, geographic terrain, or tunnels.
If your vehicle loses battery power for any reason
(including during or after an accident), the SOS Call
system, among other vehicle systems, will not operate.

SAFETY
SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The ABS provides increased vehicle stability and brake
performance under most braking conditions. The system
automatically prevents wheel lock and enhances vehicle
control during braking.
The ABS performs a self-check cycle to ensure that the
ABS is working properly each time the vehicle is started
and driven. During this self-check, you may hear a slight
clicking sound as well as some related motor noises.
The ABS is activated during braking when the system
detects one or more wheels are beginning to lock. Road
conditions such as ice, snow, gravel, bumps, railroad
tracks, loose debris, or panic stops may increase the
likelihood of ABS activation(s).
You also may experience the following normal
characteristics when the ABS activates:
ABS motor noise or clicking sounds (you may continue
to hear for a short time after the stop)
 Brake pedal pulsations
 A slight drop of the brake pedal at the end of the stop
The ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification may
result in degraded ABS performance.
Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS Warning Light will turn on when the ignition
is placed in the ON/RUN mode and may stay on for as long
as four seconds.
If the ABS Warning Light remains on or comes on while
driving, it indicates that the anti-lock portion of the brake
system is not functioning and that service is required.
However, the conventional brake system will continue to
operate normally if the ABS Warning Light is on.
If the ABS Warning Light is on, the brake system should be
serviced as soon as possible to restore the benefits of
Anti-Lock Brakes. If the ABS Warning Light does not come
on when the ignition is placed in the ON/RUN mode, have
the light repaired as soon as possible.

REAR SEAT REMINDER ALERT (RSRA) —
I
F EQUIPPED

RSRA alerts you through a visual and auditory notification
of the possible presence of an object, passenger, or pet in
the rear seats if a rear door was opened up to 10 minutes
before the ignition was placed in the ON/RUN position.
RSRA does not directly detect objects, passengers, or pets
in the rear seats. When the previous conditions are met,
RSRA displays the message “Check Rear Seat” on the
instrument cluster display and sounds an auditory alert
upon the driver placing the ignition in the OFF position to
exit the vehicle.
WARNING!
 The ABS contains sophisticated electronic equip -
ment that may be susceptible to interference caused
by improperly installed or high output radio transmit -
ting equipment. This interference can cause possible
loss of anti-lock braking capability. Installation of
such equipment should be performed by qualified
professionals.
 Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
 The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or the
traction afforded.
 The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
 The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner that could jeopardize the user’s safety or the
safety of others.

ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
If applicable, refer to the “Hybrid Supplement” for
additional information.
Your vehicle is equipped with an advanced Electronic
Brake Control (EBC) system. This system includes
Anti-Lock Brake System (ABS), Brake Assist System (BAS),
Electronic Brake Force Distribution (EBD), Electronic Roll
Mitigation (ERM), Electronic Stability Control (ESC), Hill
Start Assist (HSA), and Traction Control System (TCS). These systems work together to enhance both vehicle
stability and control in various driving conditions.
Your vehicle may also be equipped with Hill Descent
Control (HDC), Rain Brake Support (RBS), Ready Alert
Braking (RAB), and Trailer Sway Control (TSC).
Brake System Warning Light
The red Brake System Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may stay on for
as long as four seconds.
If the Brake System Warning Light remains on or comes on
while driving, it indicates that the brake system is not
functioning properly and that immediate service is
required. If the Brake System Warning Light does not
come on when the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sensing
the rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit
of the system, you must apply continuous braking
pressure during the stopping sequence (do not “pump”
the brakes). Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake pedal is
released, the BAS is deactivated.
Electronic Brake Force Distribution (EBD)
EBD manages the distribution of the braking torque
between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent overslip
of the rear wheels to avoid vehicle instability, and to
prevent the rear axle from entering ABS before the front
axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by monitoring
the driver’s steering wheel input and the speed of the
vehicle. When ERM determines that the rate of change of
the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during severe or
evasive driving maneuvers; it cannot prevent wheel lift
due to other factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
WARNING!

Before exiting a vehicle, always come to a complete
stop, then shift the automatic transmission into
PARK and apply the parking brake.
 Always make sure the keyless ignition node is in the
OFF position, key fob is removed from the vehicle
and vehicle is locked.
 Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or fatally
injured. Children should be warned not to touch the
parking brake, brake pedal or the gear selector.
 Do not leave children or animals inside parked vehi -
cles in hot weather. Interior heat buildup may cause
serious injury or death.
WARNING!
The Brake Assist System (BAS) cannot prevent the natu -
ral laws of physics from acting on the vehicle, nor can it
increase the traction afforded by prevailing road condi -
tions. BAS cannot prevent collisions, including those
resulting from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. The capabilities of a
BAS-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopardize
the user's safety or the safety of others.
