Turn Signals
Move the multifunction lever up or down and
the  arrows  on  each  side  of  the  instrument
cluster flash to show proper operation of the
front and rear turn signal lights.
NOTE:
If either light remains on and does not flash,
or there is a very fast flash rate, check for a
defective  outside  light  bulb.  If  an  indicator
fails  to  light  when  the  lever  is  moved,  it
would  suggest  that  the  indicator  bulb  is
defective.
Lights-On Reminder
If  the  headlights,  parking  lights,  or  cargo
lights  are  left on after the  ignition is placed
in the OFF position, a chime will sound when
the driver’s door is opened.
Headlight Leveling System — If Equipped 
Your vehicle may be equipped with a headlight
leveling  system.  This  system  allows  the  driver
to  maintain  proper  headlight  beam  position
with the road surface regardless of vehicle load.
The control switch is located on the instrument
panel next to the dimmer control.
Headlight Leveling Control
To operate, rotate the control switch until the
appropriate  number,  which  corresponds  to
the  load  listed  on  the  chart,  aligns  with  the
indicator line on the switch.

source is set to ignition.
For  more  information,  refer  to  “Uconnect
Settings”  in  “Multimedia”  in  your  Owner’s
Manual.
For  the  connection  and  installation  of  your
electrical  devices  refer  to  your  authorized
dealership.
ROOF LUGGAGE RACK — IF 
EQUIPPED  
NOTE:
Roof  rack  applications  are  for  Hard  Top
models  ONLY.
The load carried on the roof, when equipped
with a luggage rack, must not exceed 100 lbs
(45 kg), this includes the weight of the cross -
bars, and  it  should  be  uniformly  distributed
over the cargo area.
Crossbars  should  always  be  used  whenever
cargo  is  placed  on  the  roof  rack.  Check  the
straps  frequently  to  be  sure  that  the  load
remains securely attached.
NOTE:
Crossbars can be purchased at an authorized
dealer through Mopar parts.
External racks do not increase the total load
carrying capacity of the vehicle. Be sure that
the  total  occupant  and  luggage  load  inside
the  vehicle,  plus  the  load  on  the  luggage
rack,  do  not  exceed  the  maximum  vehicle
load capacity. WARNING!
To avoid serious injury or death:
Do not insert any objects into the receptacles.
Do not touch with wet hands.
Close the lid when not in use.
If this outlet is mishandled, it may cause
an electric shock and failure.

ENVIRONMENTAL PROTECTION 
SYSTEMS — IF EQUIPPED
Gasoline  Particulate  Filter  (GPF)  —  2.0L  T4
Petrol Versions Only
The Gasoline Particulate Filter is a mechan-
ical  filter,  integral  to  the  exhaust  system,
which  physically  traps  carbon  particles present  in  the  exhaust  gases  of  2.0L  T4
petrol engines.
The  particulate  filter  is  needed  to  eliminate
almost  all  carbon  particle  emissions  in
compliance  with  current/future  regulations
and standards.
Since this filter physically traps particulates,
it  must  be  cleaned  (regenerated)  during
normal  driving  operation  to  remove  carbon
particles.  The  regeneration  procedure  is
controlled  automatically  by  the  engine
control unit according to the filter conditions
and car use conditions.
The following may occur during regeneration:
increased  levels  of  noise  vibration  and
harshness  (NVH)  and  reduced  engine
performance.
Dedicated  messages  can  appear  in  the
instrument  cluster display as a result  of  the
condition  of  the  filter.  Refer  to  the  opening
paragraph  of  the  "Warning  Lights  And
Messages" section for further information.
 WARNING!
Cargo  must  be  securely  tied  down  before
driving  your  vehicle.  Improperly  secured
loads  can  fly  off  the  vehicle,  particularly
at  high  speeds,  resulting  in  personal
injury or property damage. Follow the roof
rack cautions when carrying cargo on your
roof rack.
 CAUTION!
To  avoid  damage  to  the  roof  rack  and
vehicle, do not exceed the maximum roof
rack  load  capacity.  Always  distribute
heavy  loads  as  evenly  as  possible  and
secure the load appropriately.
Long loads, which extend over the wind
-
shield,  should  be  secured  to  both  the
front and rear of the vehicle.
Place  a  blanket  or  other  protection
between the  surface  of  the  roof and  the
load.
Travel  at  reduced  speeds  and  turn
corners  carefully  when  carrying  large  or
heavy  loads  on  the  roof  rack.  Wind
forces,  due  to  natural  causes  or  nearby
truck  traffic,  can  add  sudden  upward
loads.  It  is  recommended  to  not  carry
large flat  loads, such  as  wood  panels  or
surfboards, which may result in damage
to the cargo or your vehicle.
Load  should  always  be  secured  to  cross
bars  first,  with  tie  down  loops  used  as
additional securing points if needed. Tie
loops are intended as supplementary tie
down  points only. Do not use ratcheting
mechanisms  with  the  tie  loops.  Check
the straps frequently to be sure that the
load remains securely attached.
 CAUTION! (Continued)

VEHICLE LOADING   
Weights Label
As required by local regulations, your vehicle
has a weights label affixed to the driver's side
door or pillar.Weights Label (Example)
This label contains:
1. The manufacturer’s company name
2. The whole vehicle type-approval number
3. The Vehicle Identification Number (VIN) 4. Gross Vehicle Weight Rating (GVWR)
5. Gross Combined Weight Rating (GCWR)
6. Front Gross Axle Weight Rating (FGAWR)
7. Rear Gross Axle Weight Rating (RGAWR)
NOTE:
For  specific  markets  the  label  could  be
different, respect the one shown in the image
contains: the GVWR, GAWR front and rear.
Gross Vehicle Weight Rating (GVWR) 
The  Gross  Vehicle  Weight  Rating  (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 passen
-
gers, options and cargo.
Gross Axle Weight Rating (GAWR)
The Gross Axle Weight Rating (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 compo -
nents sometimes specified by purchasers for
increased  durability  does  not  necessarily
increase the vehicle's GVWR.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book  Page 174

Curb Weight
The curb weight of a vehicle is defined as the
total  weight  of  the  vehicle  with  all  fluids,
including vehicle fuel, at full capacity condi-
tions, and with no occupants or cargo loaded
into  the  vehicle.  The  front  and  rear  curb
weight  values  are  determined  by  weighing
your  vehicle  on  a  commercial  scale  before
any occupants or cargo are added.
Loading
The actual total weight and the weight of the
front  and  rear  of  your  vehicle  at  the  ground
can best be determined by weighing it when
it is loaded and ready for operation. The entire vehicle should first be weighed on
a commercial scale to ensure that the GVWR
has  not  been  exceeded.  The  weight  on  the
front and  rear of the  vehicle should then be
determined  separately  to  be  sure  that  the
load is properly distributed over the front and
rear  axle.  Weighing  the  vehicle  may  show
that  the  GAWR  of  either  the  front  or  rear
axles has been exceeded but the total load is
within  the  specified  GVWR.  If  so,  weight
must  be shifted  from front  to  rear  or  rear to
front  as  appropriate  until  the  specified
weight limitations are met. Store the heavier
items  down low and be sure that the weight
is  distributed  equally.  Stow  all  loose  items
securely before driving.Improper  weight  distributions  can  have  an
adverse effect on the way your vehicle steers
and handles and the way the brakes operate.
TRAILER TOWING 
Trailer Towing Weights (Maximum Trailer Weight Ratings)    
 CAUTION!
Do  not  load  your  vehicle  any  heavier  than
the  GVWR  or  the  maximum  front  and  rear
GAWR. If you do, parts on your vehicle can
break,  or  it  can  change  the  way  your
vehicle  handles.  This  could  cause  you  to
lose  control.  Also  overloading  can  shorten
the life of your vehicle.

Tire Pressures For High Speed Operation 
The  manufacturer  advocates  driving  at  safe
speeds  and  within  posted  speed  limits.
Where  speed  limits  or  conditions  are  such
that the vehicle can be driven at high speeds,
maintaining correct tire inflation pressure is
very  important.  Increased  tire  pressure  and
reduced vehicle loading may be required for
high-speed  vehicle  operation.  Refer  to  an
authorized  tire  dealer  or  original  equipment
vehicle  dealer  for  recommended  safe  oper-
ating  speeds,  loading  and  cold  tire  inflation
pressures.
Radial Ply Tires 
Tire Repair
If  your  tire  becomes  damaged,  it  may  be
repaired if it meets the following criteria:
The tire has not been driven on when flat.
The  damage  is  only  on  the  tread  section  of
your tire (sidewall damage is not repairable).
The puncture is no greater than a ¼ of an
inch (6 mm).
Consult  an  authorized  tire  dealer  for  tire
repairs and additional information.
Damaged  Run  Flat  tires,  or  Run  Flat  tires
that  have  experienced  a  loss  of  pressure
should be replaced immediately with another
Run  Flat  tire  of  identical  size  and  service
description (Load Index and Speed Symbol).
Replace the tire pressure sensor as well as it
is not designed to be reused.
Run Flat Tires — If Equipped
Run  Flat  tires  allow  you  the  capability  to
drive 50 miles (80 km) at 50 mph (80 km/h)
after  a  rapid  loss  of  inflation  pressure.  This
rapid  loss  of  inflation  is  referred  to  as  the
Run  Flat  mode.  A  Run  Flat  mode  occurs
when the tire inflation pressure is of/or below
14 psi (96 kPa). Once a Run Flat tire reaches
the run flat mode it has limited driving capa -
bilities  and  needs  to  be  replaced  immedi -
ately. A Run Flat tire is not repairable. When
a  run  flat  tire  is  changed  after  driving  with
underinflated  tire  condition,  please  replace
the  TPM  sensor  as  it  is  not  designed  to  be
reused  when  driven  under  run  flat mode  14
psi (96 kPa) condition.
NOTE:
TPM  Sensor  must  be  replaced  after  driving
the vehicle on a flat tire condition.
It  is  not  recommended  driving  a  vehicle
loaded  at  full  capacity  or  to  tow  a  trailer
while a tire is in the run flat mode.
See  the  tire  pressure  monitoring  section  for
more information.
 WARNING!
High speed driving with your vehicle under
maximum  load  is  dangerous.  The  added
strain  on  your  tires  could  cause  them  to
fail. You could have a serious collision. Do
not drive a vehicle loaded to the maximum
capacity  at  continuous  speeds  above
75 mph (120 km/h).
 WARNING!
Combining radial ply tires with other types
of  tires  on  your  vehicle  will  cause  your
vehicle  to  handle  poorly.  The  instability
could  cause  a  collision.  Always  use  radial
ply  tires  in  sets  of  four.  Never  combine
them with other types of tires.

(Continued)
NOTE:
Wheel  Valve  Stem must be replaced  as  well
when  installing  new  tires  due  to  wear  and
tear in existing tires.
Keep  dismounted  tires  in  a  cool,  dry  place
with  as  little  exposure  to  light  as  possible.
Protect  tires  from  contact  with  oil,  grease,
and gasoline.
Replacement Tires 
The  tires  on  your  new  vehicle  provide  a
balance of many characteristics. They should
be  inspected  regularly  for  wear  and  correct
cold  tire  inflation  pressures.  The  manufac-
turer strongly recommends that you use tires
equivalent  to  the  originals  in  size,  quality
and  performance  when  replacement  is
needed.  Refer  to  the  paragraph  on  “Tread
Wear Indicators” in this section. Refer to the
Tire and  Loading Information placard  or  the
Vehicle Certification Label for the size desig -
nation  of  your  tire.  The  Load  Index  and
Speed  Symbol for  your tire  will  be found on
the original equipment tire sidewall.
It  is  recommended  to  replace  the  two  front
tires or two rear tires as a pair. Replacing just
one  tire  can  seriously  affect  your  vehicle’s handling.  If you  ever replace  a wheel, make
sure  that  the  wheel’s  specifications  match
those of the original wheels.
It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifica
-
tions or capability. Failure to use equivalent
replacement  tires  may  adversely  affect  the
safety, handling, and ride of your vehicle. WARNING!
Do not use a tire, wheel size, load rating,
or speed rating other than that specified
for  your  vehicle.  Some  combinations  of
unapproved tires and wheels may change
suspension dimensions and performance
characteristics,  resulting  in  changes  to
steering,  handling,  and  braking  of  your
vehicle.  This  can  cause  unpredictable
handling  and  stress  to  steering  and
suspension components.  You could lose
control  and  have  a  collision  resulting  in
serious injury or death. Use only the tire
and  wheel  sizes  with  load  ratings
approved for your vehicle.
Never use a tire with a smaller load index
or  capacity,  other  than  what  was  origi -
nally  equipped  on your  vehicle.  Using  a
tire with a smaller load index could result
in tire overloading and failure. You could
lose control and have a collision.
Failure  to  equip  your  vehicle  with  tires
having  adequate  speed  capability  can
result  in  sudden  tire  failure  and  loss  of
vehicle control.
 CAUTION!
Replacing  original  tires  with  tires  of  a
different  size  may  result  in  false
speedometer and odometer readings.
