2023 CHRYSLER PACIFICA tire size

GETTING TO KNOW YOUR INSTRUMENT PANEL107
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire pressure
telltale when one or more of your tires is significantly
underinflated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check your tires
as soon as possible, and inflate them to the proper
pressure. Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underinflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale. Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or
wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to
function properly.

CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning 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. Aftermarket wheels can cause
sensor damage. 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 dealer to have your
sensor function checked.

STARTING AND OPERATING121
ACTIVE NOISE CANCELLATION
Your vehicle is equipped with an Active Noise Cancellation
system. This system is designed to address exhaust and
engine noise. The system relies on four microphones
embedded in the headliner, which monitor exhaust and
engine noise, and assists an onboard frequency
generator, which creates counteracting sound waves in
the audio system’s speakers. This helps keep the vehicle
quiet at idle and during drive.
POWER STEERING
The electric power steering system will provide increased
vehicle response and ease of maneuverability. The power
steering system adapts to different driving conditions. If the Steering icon is displayed and the “Power Steering
System Over Temp” message is displayed on the
instrument cluster screen, this indicates an over
temperature condition in the 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
Úpage 102.
If the “Service Power Steering" or "Power
Steering Assist Off - Service System” message
and a steering wheel icon are displayed on the
instrument cluster screen, it indicates that the
vehicle needs to be taken to an authorized dealer for
service. It is likely the vehicle has lost power steering
assistance
Úpage 102.
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.
 The power steering system is fully electric; it requires
no power steering fluid.
 If the condition persists, see an authorized dealer for
service.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is designed 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, pressing
the accelerator pedal or shifting out of DRIVE (D) will
automatically re-start the engine.
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 driver key
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.
To Activate Auto STOP/START, 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 within the Stop/Start section
Úpage 102.
 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 throughout the Auto Stop/Start process.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire size
may cause premature wear of the driveline
components.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.

124STARTING AND OPERATING
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
When the Cruise Control is set, you can increase speed by
pushing the SET (+) button, or decrease speed by pushing
the SET (-) button.
U.S. Speed (mph)
 Pushing the SET (+), or SET (-) button once will result in
a 1 mph speed adjustment. Each subsequent tap of
the button results in an adjustment of 1 mph.
 If the button is continually pushed, the set speed will
continue to adjust in 5 mph increments until the button
is released. The new set speed is reflected in the instru -
ment cluster display.
Metric Speed (km/h)
 Pushing the SET (+), or SET (-) button once will result in
a 1 km/h speed adjustment. Each subsequent tap of
the button results in an adjustment of 1 km/h.
 If the button is continually pushed, the set speed will
continue to adjust in 10 km/h increments until the
button is released. The new set speed is reflected in
the instrument cluster display.
To Accelerate For Passing
While the Cruise Control is set, press the accelerator to
pass as you would normally. When the pedal is released,
the vehicle will return to the set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to maintain the
vehicle set speed.
The Cruise Control system maintains speed up and down
hills. A slight speed change on moderate hills is normal.
On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES button
and release. Resume can be used at any speed above
20 mph (32 km/h).
To Deactivate
A tap on the brake pedal, or pushing the CANC button, or
normal brake pressure will deactivate the Cruise Control
system without erasing the set speed from memory.
Pushing the on/off button or placing the ignition in the OFF
position erases the set speed from memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by cruise control while traveling on
highways and major roadways. However, it is not a safety
system and not designed to prevent collisions. The Cruise
Control function performs differently
Úpage 123.
ACC will allow you to keep Cruise Control engaged in light
to moderate traffic conditions without the constant need
to reset your Cruise Control. ACC utilizes a radar sensor
and a forward facing camera designed to detect a vehicle
directly ahead of you.
NOTE:
 If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or accelerate (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead.
 Any chassis/suspension or tire size modifications to
the vehicle will affect the performance of the Adaptive
Cruise Control and Forward Collision Warning system.
 Fixed Speed Cruise Control will not detect vehicles
directly ahead of you. Always be aware of the feature
selected
Úpage 312.
WARNING!
Cruise Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose control
and have an accident. Do not use Cruise Control in
heavy traffic or on roads that are winding, icy,
snow-covered or slippery.

STARTING AND OPERATING137

PARKSENSE ACTIVE PARK ASSIST SYSTEM —
IF EQUIPPED

The ParkSense Active Park Assist system is intended to
assist the driver during parallel and perpendicular parking
maneuvers by identifying a proper parking space,
providing audible/visual instructions, and controlling the
steering wheel. The ParkSense Active Park Assist system
is defined as “semi-automatic” since the driver maintains
control of the accelerator, gear selector and brakes.
Depending on the driver's parking maneuver selection, the
ParkSense Active Park Assist system is capable of
maneuvering a vehicle into a parallel or a perpendicular
parking space on either side (i.e., driver side or passenger
side).
NOTE:
The driver is always responsible for controlling the
vehicle, responsible for any surrounding objects, and
must intervene as required.
 The system is designed to assist the driver and not to
substitute the driver.
 During a semi-automatic maneuver, if the driver
touches the steering wheel after being instructed to
remove their hands from the steering wheel, the
system will cancel, and the driver will be required to
manually complete the parking maneuver.
 The system may not work in all conditions (e.g. environ -
mental conditions such as heavy rain, snow, etc., or if
searching for a parking space that has surfaces that
will absorb the ultrasonic sensor waves). 
New vehicles from the dealership must have at least
30 miles (48 km) accumulated before the ParkSense
Active Park Assist system is fully calibrated and
performs accurately. This is due to the system’s
dynamic vehicle calibration to improve the perfor -
mance of the feature.
 The use of wheels and tires that are different size to the
original equipment could affect the operation of the
system.
ENABLING AND DISABLING THE
P
ARKSENSE ACTIVE PARK ASSIST

The ParkSense Active Park Assist system will turn off
automatically for any of the following conditions:
 Parking maneuver is completed.
 Vehicle speed is greater than 18 mph (30 km/h) when
searching for a parking space.
 Vehicle speed is greater than 5 mph (7 km/h) during
active steering guidance into the parking space. 
Steering wheel is touched during active steering guid -
ance into the parking space.
 ParkSense switch is pushed.
 The driver’s door is opened.
 The liftgate is opened.
 Electronic Stability Control/Anti-Lock Braking System

REVERSE. If the maneuver cannot be completed within
eight shifts, the system will cancel and the instrument
cluster display will instruct the driver to complete the
maneuver manually.
The ParkSense Active Park Assist system will only operate
and search for a parking space when the following
conditions are present:
 The gear selector is in DRIVE.
 The ignition is in the RUN position.
 The ParkSense Active Park Assist switch is activated.
 The driver’s door is closed.
 The liftgate is closed.
 Vehicle speed is less than 15 mph (25 km/h).
 The outer surface and the underside of the front and
rear fascias/bumpers are clean and clear of snow, ice,
mud, dirt or other obstructions.

STARTING AND OPERATING147
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.
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 axle. 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.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.TRAILER TOWING
NOTE:Trailer towing is not permitted for the Plug-in Hybrid
Electric Vehicle (PHEV).
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.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
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
Úpage 146.
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.

23_RUP_OM_EN_USC_t.book Page 147

148STARTING AND OPERATING
Gross Trailer Weight (GTW)
GTW is the weight of the trailer plus the weight of all cargo,
consumables and equipment (permanent or temporary)
loaded in or on the trailer in its "loaded and ready for
operation" condition.
The recommended way to measure GTW is to put your fully
loaded trailer on a vehicle scale. The entire weight of the
trailer must be supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of your vehicle
and trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR
Úpage 146.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch ball by
the trailer. You must consider this as part of the load on
your vehicle.
Trailer Frontal Area
The Frontal Area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that can be
installed between the hitch receiver and the trailer tongue
that typically provides adjustable friction associated with
the telescoping motion to dampen any unwanted trailer
swaying motions while traveling.
The electronic TSC (if equipped), recognizes a swaying
trailer and automatically applies individual wheel brakes
and/or reduces engine power to attempt to eliminate the
trailer sway.
Weight-Carrying Hitch
A Weight-Carrying Hitch supports the trailer tongue weight,
just as if it were luggage located at a hitch ball or some
other connecting point of the vehicle. These kinds of
hitches are commonly used to tow small and medium
sized trailers.
Weight-Distributing Hitch
A weight-distributing hitch works by applying leverage
through spring (load) bars. They are typically used for
heavier loads to distribute trailer tongue weight to the tow
vehicle's front axle and the trailer axle(s). When used in
accordance with the manufacturer’s directions, it provides
for a more level ride, offering more consistent steering and
brake control thereby enhancing towing safety. The
addition of a friction/hydraulic sway control also dampens
sway caused by traffic and crosswinds and contributes
positively to tow vehicle and trailer stability. TSC and a
weight-distributing (load equalizing) hitch are
recommended for heavier TW and may be required
depending on vehicle and trailer configuration/loading to
comply with GAWR requirements.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose control
of the vehicle and have a collision.
WARNING!
An improperly adjusted weight-distributing hitch
system may reduce handling, stability, braking
performance, and could result in a collision.
 Weight-distributing systems may not be compatible
with surge brake couplers. Consult with your hitch
and trailer manufacturer or a reputable Recreational
Vehicle dealer for additional information.

23_RUP_OM_EN_USC_t.book Page 148

152STARTING AND OPERATING
Towing Requirements — Tires
Do not attempt to tow a trailer while using a compact
spare tire.
 Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.
 Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle.
 Check the trailer tires for proper tire inflation pressures
before trailer usage.
 Check for signs of tire wear or visible tire damage
before towing a trailer.
 Replacing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits.
 For further information
Úpage 291.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
 An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu -
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.
 Trailer brakes are recommended for trailers over
1,000 lb (453 kg) and required for trailers in excess of
2,000 lb (907 kg).
Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four and seven-pin
wiring harness. Use a factory approved trailer harness and
connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring
harness.
WARNING!

Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have brakes
when you need them and could have an accident.
 Towing any trailer will increase your stopping distance.
When towing, you should allow for additional space
between your vehicle and the vehicle in front of you.
Failure to do so could result in an accident.

CAUTION!
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.

23_RUP_OM_EN_USC_t.book Page 152

SAFETY189
Electronic Stability Control (ESC)
ESC enhances directional control and stability of the
vehicle under various driving conditions. ESC corrects for
oversteering or understeering of the vehicle by applying
the brake of the appropriate wheel(s) to assist in
counteracting these conditions. Engine power may also be
reduced to help the vehicle maintain the desired path.
Oversteer — when the vehicle is turning more than
appropriate for the steering wheel position.
 Understeer — when the vehicle is turning less than
appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the oversteer
or understeer condition.
The ESC Activation/Malfunction Indicator Light located in
the instrument cluster will start to flash as soon as the ESC
system becomes active. The ESC Activation/Malfunction
Indicator Light also flashes when the TCS is active. If the ESC Activation/Malfunction Indicator Light begins to flash
during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
ESC Operating Modes
Depending upon model and mode of operation, the ESC
system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions.
Alternate ESC modes should only be used for specific
reasons as noted in the following paragraphs.
Partial Off
This mode may be useful if the vehicle becomes stuck.
This mode may modify TCS and ESC thresholds for
activation, which allows for more wheel spin than normally
allowed.
To enter the “Partial Off” mode, momentarily push the ESC
OFF button and the ESC OFF Indicator Light will illuminate.
To turn the ESC on again, momentarily push the ESC OFF
button and the ESC OFF Indicator Light will turn off.
NOTE:When driving with snow chains, or when starting off in
deep snow, sand, or gravel, it may be desirable to allow
more wheel spin. This can be accomplished by momen
-
tarily pushing the ESC OFF button to enter partial mode
“Partial Off” mode. Once the situation requiring “Partial
Off” mode is overcome, turn ESC back on by momentarily
pushing the ESC OFF button. This may be done while the
vehicle is in motion.
WARNING!

Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.

WARNING!

 Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. ESC cannot prevent accidents, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC also
cannot prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the condi -
tions. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESC
equipped vehicle must never be exploited in a reckless
or dangerous manner which could jeopardize the
user’s safety or the safety of others.

 Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris -
tics of your vehicle, and may negatively affect the
performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any vehicle
modification or poor vehicle maintenance that
reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.
