as a result of the Uconnect system switching
between  Power  Top  Closed  and  Power  Top
Open audio modes.
Opening The Power Top
Express Mode
Push  the  open  switch  and  release  it  within
one-half  second.  The  power  top  will  open
automatically  to  the  open  position.  This  is
called “Express Open”. During Express Open
operation,  any  movement  of  the  switch  will
stop the power top.
Manual Mode
To  open  the  power  top  manually,  push  and
hold the open switch. The power top will stop
automatically  at  the  open  position.  Any
release of the switch will stop the movement.
The  power  top  will  remain  in  a  partially
opened  position  until  the  switch  is  pushed
and held again.
Closing The Power Top
Express Mode
Push  the  close  switch  and  release  it  within
one-half  second.  The  power  top  will  close
fully  and  stop  automatically.  This  is  called
“Express Close”. During Express Close oper-
ation,  any  movement  of  the  switch  will  stop
the power top.
Manual Mode
To  close  the  power  top  manually,  push  and
hold  the  close  switch.  The  power  top  will

The  “ESC  Activation/Malfunction  Indicator
Light”  (located  in  the  instrument  cluster)
starts to flash as soon as the tires lose trac-
tion  and  the  ESC  system  becomes  active.
The  “ESC  Activation/Malfunction  Indicator
Light” also flashes when 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.
NOTE:
The  “ESC  Activation/Malfunction  Indi -
cator  Light”  and  the  “ESC  OFF  Indicator
Light”  come  on  momentarily  each  time
the ignition is turned ON.
Each  time  the  ignition  is  turned  ON,  the
ESC system will be on even if it was turned
off previously.
The  ESC  system  will  make  buzzing  or
clicking  sounds  when  it  is  active.  This  is
normal;  the  sounds  will  stop  when  ESC
becomes  inactive  following  the  maneuver
that caused the ESC activation. The  “ESC  OFF  Indicator  Light”
indicates the customer has elected
to  have  the  Electronic  Stability
Control (ESC) in a reduced mode.
Hill Descent Control (HDC) — If Equipped  
Hill  Descent  Control  (HDC)  is  intended  for
low speed off road driving while in 4L Range.
HDC  maintains  vehicle  speed  while
descending hills during various driving situa
-
tions. HDC controls vehicle speed by actively
controlling the brakes.
HDC has three states:
1. Off  (feature  is  not  enabled  and  will  not activate)
2. Enabled  (feature  is  enabled  and  ready but activation conditions are not met, or
driver is actively overriding with brake or
throttle application)
3. Active  (feature  is  enabled  and  actively controlling vehicle speed) Enabling HDC
HDC is enabled by pushing the HDC switch,
but  the  following  conditions  must  also  be
met to enable HDC:
Driveline is in 4L Range
Vehicle speed is below 5 mph (8 km/h)
Park brake is released
Driver  door  is  closed  (If  doors  are
attached,  then  door  must  be  closed.  If
doors  are  detached,  then  driver  seatbelt
must be buckled)
Activating HDC
Once  HDC  is  enabled  it  will  activate  auto -
matically if driven down a grade of sufficient
magnitude. The set speed for HDC is select -
able  by  the  driver,  and  can  be  adjusted  by
using  the  gear  shift  +/-.  The  following
summarizes the HDC set speeds:
HDC Target Set Speeds
P  =  No  set  speed.  HDC  may  be  enabled
but will not activate
R = 0.6 mph (1 km/h)
N = 1.2 mph (2 km/h)
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book  Page 83   

SAFETY
84
D = 0.6 mph (1 km/h)
1st = 0.6 mph (1 km/h)
2nd = 1.2 mph (2 km/h)
3rd = 1.8 mph (3 km/h)
4th = 2.5 mph (4 km/h)
5th = 3.1 mph (5 km/h)
6th = 3.7 mph (6 km/h)
7th = 4.3 mph (7 km/h)
8th = 5.0 mph (8 km/h)
9th = 5.6 mph (9 km/h) – If Equipped
NOTE:
During  HDC  the  +/- shifter  input is used for
HDC  target  speed  selection,  but  will  not
affect  the  gear  chosen  by  the  transmission.
When actively controlling HDC, the transmis -
sion  will  shift  appropriately  for  the
driver-selected set speed and corresponding
driving conditions. Driver Override
The driver may override HDC activation with
throttle or brake application at anytime.
Deactivating HDC
HDC will be deactivated but remain available
if any of the following conditions occur:
Driver  overrides  HDC  set  speed  with
throttle or brake application
Vehicle speed exceeds 20 mph (32 km/h)
but remains below 40 mph (64 km/h)
Vehicle  is  on  a  downhill  grade  of  insuffi -
cient  magnitude,  is  on level  ground,  or  is
on an uphill grade
Vehicle is shifted to PARK (P)
Disabling HDC
HDC will be deactivated and disabled if any
of the following conditions occur:
The driver pushes the HDC switch
The driveline is shifted out of 4L Range
The park brake is applied
Driver  door  opens  (Driver  door  opens  if
doors  are  attached  or  driver  seatbelt  is
unbuckled if doors are detached)
The vehicle is driven greater than 20 mph
(32 km/h) for greater than 70 seconds
The vehicle is driven greater than 40 mph
(64 km/h) (HDC exits immediately)
HDC detects excessive brake temperature
Feedback To The Driver
The instrument cluster has an HDC icon and
the HDC switch has an indicator light, which
offers feedback to the driver about the state
HDC is in.
The cluster icon and switch indicator light
will  illuminate  and  remain  on  solid  when
HDC  is  enabled  or  activated.  This  is  the
normal operating condition for HDC.
The cluster icon and switch indicator light
will  flash  for  several  seconds  then  extin -
guish  when  the  driver  pushes  the  HDC
switch but enable conditions are not met.
The cluster icon and switch indicator light will
flash for several seconds then extinguish when
HDC disables due to excess speed.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book  Page 84   

85
The cluster icon and switch indicator light
will  flash  when  HDC  deactivates  due  to
overheated  brakes.  The  flashing  will  stop
and  HDC  will  activate  again  once  the
brakes have cooled sufficiently.
Hill Start Assist (HSA)  
The Hill Start Assist (HSA) system is designed to
mitigate roll  back from a complete stop while on
an  incline.  If  the  driver  releases  the  brake  while
stopped on an incline, HSA will continue to hold
the brake pressure for a short period. If the driver
does  not  apply  the  throttle  before  this  time
expires,  the  system  will  release  brake  pressure
and the vehicle will roll down the hill as normal.
The  following  conditions  must  be  met  in
order for HSA to activate:
The feature must be enabled
The vehicle must be stopped
Park brake must be off
Driver  door  must  be  closed.  (If  the  doors
are  attached,  then  the  door  must  be
closed. If the doors are detached then the
driver's seatbelt must be buckled)
The vehicle must be on a sufficient grade
The  gear  selection  must  match  vehicle
uphill direction (i.e., vehicle facing uphill
is in forward gear; vehicle backing uphill is
in REVERSE (R) gear)
HSA  will  work  in  REVERSE  gear  and  all
forward gears. The system will not activate
if  the  transmission  is  in  PARK  (P)  or
NEUTRAL (N). For vehicles equipped with
a  manual  transmission,  if  the  clutch  is
pressed, HSA will remain active.
Disabling And Enabling HSA
This feature  can be  turned on or turned  off.
To  change  the  current  setting,  refer  to
“Instrument Cluster  Display” in “Getting To
Know  Your  Instrument  Panel”  for  further
information.
 WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending
hills.  The  driver  must  remain  attentive  to
the  driving  conditions  and  is  responsible
for maintaining a safe vehicle speed.
 WARNING!
There  may  be  situations  where  the  Hill
Start  Assist  (HSA)  will  not  activate  and
slight  rolling  may  occur,  such as  on  minor
hills  or  with  a  loaded  vehicle,  or  while
pulling a trailer. HSA is not a substitute for
active driving involvement. It is always the
driver’s  responsibility  to  be  attentive  to
distance  to  other  vehicles,  people,  and
objects,  and  most  importantly  brake
operation  to  ensure  safe  operation  of  the
vehicle  under  all  road  conditions.  Your
complete  attention  is  always  required
while  driving  to  maintain  safe  control  of
your  vehicle.  Failure  to  follow  these
warnings can result in a collision or serious
personal injury.

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
