Vehicles With Compact Spare or Non-Matching
Full Size Spare
1. The compact spare tire or non-matching full size does not have a tire pressure
monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the
compact spare tire.
2. If you install the compact or non-matching full size spare tire in place
of a road tire that has a pressure below
the low-pressure warning limit, upon the
next ignition cycle, the TPMS Warning
Light will remain on and a chime will
sound. In addition, the graphic in the
instrument cluster will still display a
different color pressure value.
3. After driving the vehicle for up to 10 minutes above 15 mph (24 km/h),
the TPMS Warning Light will flash on and
off for 75 seconds and then remain on
solid. In addition, the instrument cluster
will display a “Service Tire Pressure
System” message for five seconds and
then display dashes (--) in place of the
pressure value. 4. For each subsequent ignition cycle, a
chime will sound, the TPMS Warning
Light will flash on and off for 75 seconds
and then remain on solid, and the instru -
ment cluster will display a “SERVICE
TIRE PRESSURE SYSTEM” message for
five seconds and then display dashes (--)
in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in
place of the compact spare or
non-matching full size, the TPMS will
update automatically. In addition, the
TPMS Warning Light will turn off and the
graphic in the instrument cluster 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
10 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this
information. Vehicles With a Full Size Matching Spare
1. If your vehicle is equipped with a
matching full-size spare wheel and tire
assembly, it has a tire pressure moni -
toring sensor, and can be monitored by
the Tire Pressure Monitoring System
(TPMS) when swapped with a low pres -
sure road tire.
2. In the event that the matching full-size spare tire is swapped with a low pressure
road tire, the next ignition switch cycle
will still show the TPMS Warning Light to
be on, a chime to sound, and the graphic
display will still show the low tire pres -
sure value in a different color.
3. Driving the vehicle for up to 10 minutes above 15 mph (24 km/h) will turn off theTPMS Warning Light as long as none of
road tires are below the low pressure
warning threshold.
TPMS Deactivation — If Equipped
The TPMS can be deactivated 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.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 96

97

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 10 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 TIRE PRES-
SURE SYSTEM” message and then display
dashes (--) in place of the pressure values.
Beginning with the next ignition cycle, the TPMS
will no longer chime or display the “SERVICE
TIRE PRESSURE 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 TPMS sensors. Then,
drive the vehicle for up to 10 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 instru -
ment cluster will display the “SERVICE TIRE
PRESSURE SYSTEM” message and then
display pressure values in place of the
dashes. On the next ignition cycle the
"SERVICE TIRE PRESSURE SYSTEM"
message will no longer be displayed as long
as no system fault exists.OCCUPANT RESTRAINT
SYSTEMS
Some of the most important safety features
in your vehicle are the restraint systems:
Occupant Restraint Systems Features
Seat Belt Systems

Eight–Speed Automatic Transmission
Your vehicle is equipped with a fuel efficient
8 speed transmission. The gear selector is
located in the center console.Transmission Gear Selector
The transmission gear selector provides
PARK, REVERSE, NEUTRAL, DRIVE and
MANUAL (AutoStick) shift positions. Manual
shifts can be made using the AutoStick shift
control. Toggling the gear selector forward (-)
or rearward (+) while in the MANUAL (Auto -
Stick) position (beside the DRIVE position)
will manually select the transmission gear,
and will display the current gear in the
instrument cluster. Refer to "AutoStick" in
this section for further information. NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position
(when pushed forward), it is probably in the
AutoStick (+/-) position (beside the DRIVE
position). In AutoStick mode, the transmis
-
sion gear (1, 2, 3, etc.) is displayed in the
instrument cluster. Move the gear selector to
the right (into the DRIVE [D] position) for
access to PARK, REVERSE, and NEUTRAL.
AutoStick
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving
you more control of the vehicle. AutoStick
allows you to maximize engine braking, elim -
inate undesirable upshifts and downshifts,
and improve overall vehicle performance.
This system can also provide you with more
control during passing, city driving, cold slip -
pery conditions, mountain driving, trailer
towing, and many other situations. Operation

To activate AutoStick mode, move the gear
selector into the MANUAL (M) position (beside
the DRIVE position). The current transmission
gear will be displayed in the instrument cluster.
In AutoStick mode, you can use the gear
selector (in the MANUAL position) to manually
shift the transmission. Tapping the gear
selector forward (-) while in the MANUAL (M)
position will downshift the transmission to the
next lower gear. Tapping the selector rearward
(+) will command an upshift.

In AutoStick mode, the transmission will
shift up or down when (+/-) is manually
selected by the driver, unless an engine
lugging or overspeed condition would result.
It will remain in the selected gear until
another upshift or downshift is chosen,
except as described below.
The transmission will automatically down
-
shift as the vehicle slows (to prevent
engine lugging) and will display the
current gear.
