(Continued)ESC Operating Modes
NOTE:
Depending upon model and mode of opera-
tion, the ESC system may have multiple
operating modes. ESC OFF Button
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
The “Partial Off” mode is intended for times
when a more spirited driving experience is
desired. This mode may modify TCS and ESC
thresholds for activation, which allows for
more wheel spin than normally allowed. This
mode may be useful if the vehicle becomes
stuck.
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 acci -
dents, 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 inap -
propriate driver input for the conditions.
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 prop -
erly maintain your vehicle, may change
the handling characteristics of your
vehicle, and may negatively affect the
performance of the ESC system.
Changes to the steering system, suspen -
sion, 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 modifica-
tion 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.

SAFETY
86
Changing the FCW status to the “Near”
setting, allows the system to warn the driver
of a possible collision with the vehicle in
front when the distance between the vehicle
in the front is much closer. This setting
provides less reaction time than the “Far”
and “Medium” settings, which allows for a
more dynamic driving experience.
NOTE:
The system will NOT retain the last setting
selected by the driver after ignition shut
down. The system will reset to Medium
sensitivity with FCW "Full On" setting
when the vehicle is restarted.
FCW may not react to irrelevant objects
such as overhead objects, ground reflec-
tions, objects not in the path of the
vehicle, stationary objects that are far
away, oncoming traffic, or leading vehicles
with the same or higher rate of speed.
If FCW is disabled, unavailable screens
will be displayed.
FCW Limited Warning
If the instrument cluster display reads “ACC/
FCW Limited Functionality” or “ACC/FCW
Limited Functionality Clean Front Wind-
shield” momentarily, there may be a condi -tion that limits FCW functionality. Although
the vehicle is still drivable under normal
conditions, the active braking may not be
fully available. Once the condition that
limited the system performance is no longer
present, the system will return to its full
performance state. If the problem persists,
see an authorized dealer.
Service FCW Warning
If the system turns off, and the instrument
cluster display reads “FCW Unavailable
Service Required”, this indicates there is an
internal system fault. Although the vehicle is
still drivable under normal conditions, have
the system checked by an authorized dealer.
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure
based on the vehicle recommended cold
placard pressure.
The tire pressure will vary with temperature
by approximately 1 psi (7 kPa) for every 12°F
(6.5°C). This means that when the outside
temperature decreases, the tire pressure will
decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is
defined as the tire pressure after the vehicle
has not been driven for at least three hours,
or driven less than 1 mile (1.6 km) after a
three hour period. The cold tire inflation
pressure must not exceed the maximum
inflation pressure molded into the tire side
-
wall. Refer to “Tires” in “Servicing And
Maintenance” for information on how to
properly inflate the vehicle’s tires. The tire
pressure will also increase as the vehicle is
driven. This is normal and there should be no
adjustment for this increased pressure.
The TPMS will warn the driver of a low tire
pressure if the tire pressure falls below the
low-pressure warning limit for any reason,
including low temperature effects and
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 the recommended cold placard
pressure.
NOTE:
Once the low tire pressure warning (TPMS
Warning Light) illuminates, you must
increase the tire pressure to the recom -
mended cold placard pressure in order for
the TPMS Warning Light to turn off.
2020_JEEP_M6_UG_UK.book Page 86

87
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 turn off once
the system receives the updated tire pres-
sures. The vehicle may need to be driven for
up to 10 minutes above 15 mph (24 km/h)
in order for the TPMS to receive this informa -
tion.
For example, your vehicle may have a recom -
mended cold (parked for more than three
hours) placard 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 low enough to turn on the “TPMS
Warning Light.” Driving the vehicle may
cause the tire pressure to rise to approxi -
mately 28 psi (193 kPa), but the TPMS
Warning Light will still be on. In this situa -
tion, the TPMS Warning Light will turn off
only after the tires are inflated to the
vehicle’s recommended cold placard pres -
sure value. NOTE:
The TPMS is not intended to replace
normal tire care and maintenance, or to
provide warning of a tire failure or condi
-
tion.
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. Underinflation 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 maintenance, and it is the driver’s
responsibility to maintain correct tire pres-
sure using an accurate tire pressure
gauge, even if underinflation has not
reached the level to trigger illumination of
the TPMS Warning Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
The system only warns the tire pressure is
low: it is not able to inflate them.
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 opera-
tion or sensor damage may result when
using replacement equipment that is not
of the same size, type, and/or style. The
TPM sensor is not designed for use on
aftermarket wheels and may contribute
to a poor overall system performance or
sensor damage. Customers are encour -
aged to use OEM wheels to assure proper
TPM feature operation.
Using aftermarket tire sealants may
cause the Tire Pressure Monitoring
System (TPMS) sensor to become inop -
erable. After using an aftermarket tire
sealant it is recommended that you take
your vehicle to your authorized dealer to
have your sensor function checked.
After inspecting or adjusting the tire
pressure always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which
could damage the TPMS sensor.

the ignition switch is first in the ON/RUN
position.
The Air Bag Warning Light remains on
after the four to eight-second interval.
The Air Bag Warning Light comes on inter -
mittently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any
engine related gauges are not working, the
Occupant Restraint Controller (ORC) may
also be disabled. In this condition the air bags may not be ready to inflate for your
protection. Have an authorized dealer service
the air bag system immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light
is detected, which could affect the Supple -
mental Restraint System (SRS), the Redun -
dant Air Bag Warning Light will illuminate on
the instrument panel. The Redundant Air
Bag Warning Light will stay on until the fault
is cleared. In addition, a single chime will
sound to alert you that the Redundant Air
Bag Warning Light has come on and a fault
has been detected. If the Redundant Air Bag
Warning Light comes on intermittently or
remains on while driving have an authorized
dealer service the vehicle immediately. For additional information regarding the
Redundant Air Bag Warning Light refer to
“Getting To Know Your Instrument Panel”
section of this manual.
Front Air Bags
This vehicle has front air bags and lap/
shoulder belts for both the driver and front
passenger. The front air bags are a supple
-
ment to the seat belt restraint systems. The
driver front air bag is mounted in the center
of the steering wheel. The passenger front air
bag is mounted in the instrument panel,
above the glove compartment. The words
“SRS AIRBAG” or “AIRBAG” are embossed
on the air bag covers.

VEHICLE LOADING
Certification Label
As required by local traffic regulations, your
vehicle has a certification label affixed to the
driver's side door or pillar.
Refer to “Tire Safety” in “Servicing And
Maintenance” for further informationThis 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 indi
-
cates the Month, Day and Hour of manufac -
ture. The bar code that appears on the
bottom of the label is your VIN.
TRAILER TOWING
Common Towing Definitions
The following trailer towing related defini -
tions will assist you in understanding the
following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of
your vehicle. This includes driver, passen -
gers, cargo and tongue weight. The total load
must be limited so that you do not exceed
the GVWR. Refer to “Vehicle Loading/Vehicle
Certification Label” in “Starting And Oper -
ating” for further information.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the
weight of all cargo, consumables and equip -
ment (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 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. Refer to “Vehicle Loading/Vehicle
Certification Label” in “Starting And Oper -
ating” for further information.
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.

When towing a trailer the technically permissible laden weight may be exceeded by not more than 10% or 220 lbs (100 kg), whichever is
lower provided that the operating speed is restricted to 62 mph (100 km/h) or less.
Refer to local laws for maximum trailer towing speeds and loads.
Towing limits quoted represent the maximum towing ability of the vehicle at its Gross Combined Mass to restart on a 12 percent gradient
at sea level.
The performance and economy of all models will be reduced when used for towing.
* Trailer towing without trailer brakes is limited to 992 lbs (450 kg).
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts
could be damaged.
Then, during the first 500 miles
(805 km) that a trailer is towed, do not
drive over 50 mph (80 km/h) and do not
make starts at full throttle. This helps
the engine and other parts of the vehicle
wear in at the heavier loads.

Jack Usage Precautions
To complete the Use and Maintenance
Handbook to which this supplement is
attached, given below are some instructions
on the proper use of the jack.MaintenanceMake sure grime does not build up on the
“worm screw.”
Keep the “worm screw” lubricated.
Never modify the jack.
Conditions Of Non-Use:
Temperatures below −40°C.
On sandy or muddy ground.
On uneven ground.
On steep roads.
In extreme weather conditions: thunder -
storms, typhoons, hurricanes, blizzards,
storms, etc.
WARNING!
When using the crank, make sure it turns
freely without the risk of scraping hands
against the ground.
Even the moving parts of the jack, the
“worm screw” and joints can cause
injuries: avoid contact with them. Clean it
thoroughly if dirtied with grease.
CAUTION!
The jack is a tool designed exclusively for
changing a wheel, in case of a puncture or
damage to a tire of the vehicle on which it
is fitted or on vehicles of the same model.
Any other use, e.g. to jack up other vehicle
models or different things, is strictly
prohibited. Never use it to carry out
maintenance or repairs under the vehicle
or to change summer/winter wheels and
vice versa. Never go under the raised
vehicle. If any work under the vehicle is
necessary, contact an authorized dealer.
Incorrect placing of the jack can cause the
vehicle to drop: use it only in the positions
indicated. Do not use the jack for loads
higher than that specified on the label.
Never start the engine with vehicle raised.
If the vehicle is raised more than
necessary, everything can become more
unstable, with the risk of the vehicle
dropping violently. Therefore raise the
vehicle only as much as necessary for the
wheel/spare.
