2017 JEEP GRAND CHEROKEE flat tire

Quadra-Trac II Operating Instructions/
Precautions — If Equipped
The Quadra-Trac II transfer case is fully au-
tomatic in the normal driving 4WD AUTO
mode. The Quadra-Trac II transfer case pro-
vides 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 in-
tended 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 dam-
age 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.
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL position
without first fully engaging the parking
brake. The transfer case NEUTRAL posi-
tion disengages both the front and rear
drive shafts from the powertrain and will
allow the vehicle to roll, even if the trans-
mission is in PARK. The parking brake
WARNING!
should always be applied when the driver
is not in the vehicle.

NOTE:
If equipped with a touch screen radio all
enabling/disabling of air suspension features
must be done through the radio. Refer to
“Uconnect Settings” in “Multimedia” for fur-
ther information.
WARNING!
The air suspension system uses a high
pressure volume of air to operate the sys-
tem. To avoid personal injury or damage to
the system, see your authorized dealer for
service.
Air Suspension Modes
The Air Suspension system has multiple
modes to protect the system in unique situa-
tions:
Tire/Jack Mode

Operation With A Trailer
The operation of the sensors is automatically
deactivated when the trailer's electric plug is
inserted in the vehicle's tow hook socket. The
sensors are automatically reactivated when
the trailer's cable plug is removed.
General Warnings
If “PARKSENSE UNAVAILABLE WIPE REAR
SENSORS" or "PARKSENSE UNAVAILABLE
WIPE FRONT SENSORS” appears in the in-
strument cluster display, clean the
ParkSense sensors with water, car wash soap
and a soft cloth. Do not use rough or hard
cloths. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
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 controllingthe 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 pas-
senger side).
NOTE:
• The driver is always responsible for con-
trolling the vehicle, responsible for any
surrounding objects, and must intervene
as required.
• The system is provided 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. environmental 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) accumu-
lated before the ParkSense Active Park
Assist system is fully calibrated and per-
forms accurately. This is due to the sys-
tem’s dynamic vehicle calibration to im-
prove 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.

WARNING!
A loose tire or jack thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the
jack parts and the spare tire in the places
provided. Have the deflated (flat) tire re-
paired or replaced immediately.
Changing Procedure
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with thecone shaped end of the nut toward the
wheel. Lightly tighten the lug nuts.
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the lug nuts fully
until the vehicle has been lowered. Failure
to follow this warning may result in per-
sonal injury.
3. Lower the vehicle to the ground by turning the jack handle counterclockwise.
4. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased leverage. Tighten the
lug nuts in a star pattern until each nut
has been tightened twice. The correct
tightness of each lug nut is 130 ft-lbs
(176 N·m). If in doubt about the correct
tightness, have them checked with a
torque wrench by your authorized dealer
or service station.
NOTE:
For the SRT model the correct wheel nut
tightness is 110 ft lbs (149 N·m).
5. After 25 miles (40 km) check the lug nut torque with a torque wrench to ensure that
all lug nuts are properly seated against the
wheel.JUMP-STARTING
If your vehicle has a discharged battery it can
be jump-started using a set of jumper cables
and a battery in another vehicle or by using a
portable battery booster pack. Jump-starting
can be dangerous if done improperly so
