2019 JEEP GRAND CHEROKEE LIMITED tires

NOTE:There is no tire pressure monitoring sensor in the
spare tire. The TPMS will not be able to monitor the tire
pressure. If you install the spare tire in place of a road tire
that has a pressure below the low-pressure warning limit,
upon the next ignition switch cycle, the Tire Pressure
Monitoring System Warning Light will remain on, a chime
will sound, and the instrument cluster display will still
display a pressure value in the different color graphic
display and an “Inflate to XX” message will be displayed.
After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the Tire Pressure Monitoring System
Warning Light will flash on and off for 75 seconds and then
remain on solid. In addition, the instrument cluster display
will display a “SERVICE TPM SYSTEM message for five
seconds and then display dashes (- -) in place of the
pressure value. For each subsequent ignition switch cycle,
a chime will sound, the Tire Pressure Monitoring System
Warning Light will flash on and off for 75 seconds and then
remain on solid, and the instrument cluster display will
display a SERVICE TPM SYSTEM message for five sec-
onds and then display dashes (- -) in place of the pressure
value. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the spare tire, the
TPMS will update automatically. In addition, the Tire Pressure Monitoring System Warning
Light will turn off and the graphic in the instrument cluster
display will display a new pressure value instead of dashes
(- -), as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to receive this
information.
TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (TPMS) can be deac-
tivated if replacing all four wheel and tire assemblies (road
tires) with wheel and tire assemblies that do not have
TPMS Sensors, such as when installing winter wheel and
tire assemblies on your vehicle.
To deactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with tires not equipped with
Tire Pressure Monitoring (TPM) Sensors. Then, drive the
vehicle for 20 minutes above 15 mph (24 km/h). The TPMS
will chime, the TPMS Warning Light will flash on and off
for 75 seconds and then remain on. The instrument cluster
will display the “SERVICE TPM SYSTEM” message and
then display dashes (--) in place of the pressure values.

SAFETY 197

Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “SERVICE TPM SYSTEM”
message in the instrument cluster but dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPM
sensors. Then, drive the vehicle for up to 20 minutes above
15 mph (24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds and then
turn off. The instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display pressure values
in place of the dashes. On the next ignition cycle the
SERVICE TPM SYSTEMmessage will no longer be dis-
played as long as no system fault exists.

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline

FOUR WHEEL DRIVE OPERATION
Quadra-Trac I Operating Instructions/Precautions
— If Equipped
The Quadra-Trac I is a single-speed (HI range only) trans-
fer case, which provides convenient full-time four-wheel
drive. No driver interaction is required. The Brake Traction
Control (BTC) System, which combines standard ABS and
Traction Control, provides resistance to any wheel that is
slipping to allow additional torque transfer to wheels with
traction.
NOTE:The Quadra-Trac I system is not appropriate for
conditions where 4WD LOW range is recommended. Refer
to “Off-Road Driving Tips” in “Starting And Operating”
Quadra-Trac II Operating Instructions/Precautions
— If Equipped
The Quadra-Trac II transfer case is fully automatic in the
normal driving 4WD AUTO mode. The Quadra-Trac II
transfer case provides three mode positions:
• 4WD HI
• NEUTRAL
• 4WD LOW This transfer case is fully automatic in the 4WD HI mode.
When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at the
same speed. The 4WD LOW position is intended for loose,
slippery road surfaces only. Driving in the 4WD LOW
position on dry, hard-surfaced roads may cause increased
tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type, and circumference on each wheel.
Any difference will adversely affect shifting and cause
damage to the transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.

STARTING AND OPERATING 273

•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 performance of the feature.
The system will also continuously perform the dynamic
vehicle calibration to account for differences such as
over or under inflated tires and new tires.
Enabling And Disabling The ParkSense Active Park
Assist System
The ParkSense Active Park Assist system can be
enabled and disabled with the ParkSense Active
Park Assist switch, located on the switch panel
below the Uconnect display.
To enable the ParkSense Active Park Assist system, push
the ParkSense Active Park Assist switch once (LED turns
on).
To disable the ParkSense Active Park Assist system, push
the ParkSense Active Park Assist switch again (LED turns
off). The ParkSense Active Park Assist system will turn off
automatically for any of the following conditions:
•
The parking maneuver is completed.
• Vehicle speed greater than 18 mph (30 km/h) when
searching for a parking space.
• Vehicle speed greater than 5 mph (7 km/h) during active
steering guidance into the parking space.
• Touching the steering wheel during active steering guid-
ance into the parking space.
• Pushing the ParkSense Front and Rear Park Assist
switch.
• Driver’s door is opened.
• Rear liftgate is opened.
• Electronic Stability Control/Anti-lock Braking System
intervention.

VEHICLE LOADING
Certification Label
As required by National Highway Traffic Safety Adminis-
tration regulations, your vehicle has a certification label
affixed to the driver’s side door or pillar.
This label contains the month and year of manufacture,
Gross Vehicle Weight Rating (GVWR), Gross Axle Weight
Rating (GAWR) front and rear, and Vehicle Identification
Number (VIN). A Month-Day-Hour (MDH) number is
included on this label and indicates the Month, Day and
Hour of manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable load
weight a truck 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 in-
creased durability does not necessarily increase the vehi-
cle’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.
362 STARTING AND OPERATING

NOTE:The trailer tongue weight must be considered as
part of the combined weight of occupants and cargo, and
should never exceed the weight referenced on the Tire and
Loading Information placard. Refer to “Tires” in “Servicing
And Maintenance” for further information. The addition of
passengers and cargo may require reducing trailer tongue
load and Gross Trailer Weight (GTW). Redistributing cargo
(to the trailer) may be necessary to avoid exceeding Rear
Gross Axle Weight Rating (GAWR) of 3,700 lbs (1,678 kg).
Trailer Hitch Receiver Cover Removal (Summit
Models) — If Equipped
Your vehicle may be equipped with a trailer hitch receiver
cover, this must be removed to access the trailer hitch
receiver (if equipped). This hitch receiver cover is located
at the bottom center of the rear fascia.
1. Turn the two locking retainers located at the bottom of the hitch receiver cover a 1/4 turn counterclockwise.
NOTE: Use a suitable tool such as a coin in the slot of the
locking retainer if needed for added leverage. 2. Pull the bottom of the cover outward (towards you),
pull downwards to disengage the tabs located at the top
of the hitch receiver cover.

WARNING!(Continued)
•When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or damage
to brakes, axle, engine, transmission, steering, sus-
pension, chassis structure or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL. Always, block or
chock the trailer wheels.
• GCWR must not be exceeded.
