(Continued)
Periodic Safety Checks You Should Make 
Outside The Vehicle
Tires 
Examine tires for excessive tread wear and uneven
wear  patterns.  Check  for  stones,  nails,  glass,  or
other  objects  lodged  in  the  tread  or  sidewall.
Inspect the tread for cuts and cracks. Inspect side-
walls for cuts, cracks, and bulges. Check the wheel
nuts for tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights        
Have  someone  observe  the  operation  of  brake
lights  and  exterior  lights  while  you  work  the
controls.  Check  turn  signal  and  high  beam  indi -
cator lights on the instrument panel.
Door Latches 
Check  for  proper  closing,  latching,  and
locking.
Fluid Leaks 
Check  area  under  vehicle  after  overnight
parking  for  fuel,  coolant,  oil,  or  other  fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected, the
cause  should  be  located  and  corrected
immediately.
ALWAYS  REMOVE  THE  EXISTING
FLOOR  MAT  FROM  THE  VEHICLE 
before  installing  any  other  floor  mat.
NEVER  install  or  stack  an  additional
floor mat on top of an existing floor mat.
ONLY  install  floor  mats  designed  to  fit
your  vehicle.  NEVER  install  a  floor  mat
that  cannot  be  properly  attached  and
secured  to  your  vehicle.  If  a  floor  mat
needs  to  be  replaced,  only  use  a  FCA
approved floor mat for the specific make,
model, and year of your vehicle.
ONLY  use  the  driver’s  side  floor  mat  on
the driver’s side floor area. To check for
interference,  with  the  vehicle  properly
parked with the engine off, fully depress
the  accelerator,  the  brake,  and  the
clutch  pedal  (if  present)  to  check  for
interference.  If  your floor  mat  interferes
with the operation of any pedal, or is not
secure to the floor, remove the floor mat
from the vehicle and place the floor mat
in your trunk.
ONLY use the passenger’s side floor mat
on the passenger’s side floor area.
 WARNING! (Continued)
ALWAYS  make  sure  objects  cannot  fall
or  slide  into  the  driver’s  side  floor  area
when the vehicle is moving. Objects can
become  trapped  under  accelerator,
brake, or clutch pedals and could cause
a loss of vehicle control.
NEVER place any objects under the floor
mat  (e.g.,  towels,  keys,  etc.).  These
objects could change the position of the
floor  mat  and  may  cause  interference
with  the  accelerator,  brake,  or  clutch
pedals.
If  the  vehicle  carpet  has  been  removed
and  re-installed,  always  properly  attach
carpet  to  the  floor  and  check  the  floor
mat  fasteners  are  secure  to  the  vehicle
carpet.  Fully  depress  each  pedal  to
check  for  interference  with  the  acceler -
ator,  brake,  or  clutch  pedals  then
re-install the floor mats.
It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning,  always  check  your  floor  mat
has  been  properly  installed  and  is
secured  to  your  vehicle  using  the  floor
mat fasteners by lightly pulling mat.

ENGINE BREAK-IN 
RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle)
in your vehicle.
Drive  moderately  during  the  first  300 miles
(500 km).  After  the  initial  60 miles
(100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable.
While  cruising,  brief  full-throttle  accelera-
tion  within  the  limits  of  local  traffic  laws
contributes  to  a  good  break-in.  Wide-open
throttle acceleration in low gear can be detri -
mental and should be avoided.
The engine oil installed in the engine at the
factory  is  a  high-quality  energy  conserving
type lubricant. Oil changes should be consis -
tent  with  anticipated  climate  conditions
under which vehicle operations will occur.
For  the  recommended  viscosity  and  quality
grades,  refer  to  “Fluids  And  Lubricants”  in
“Technical Specifications”. NOTE:
A new engine may consume some oil during
its  first  few  thousand  miles  (kilometers)  of
operation.  This  should  be  considered  a
normal  part  of  the  break-in  and  not  inter
-
preted as a problem.
AUTOMATIC 
TRANSMISSION  
NOTE:
You  must  press  and  hold  the  brake  pedal
while shifting out of PARK. CAUTION!
Never  use  Non-Detergent  Oil  or  Straight
Mineral  Oil  in  the  engine  or  damage  may
result.
 CAUTION!
Shift  into  or  out  of  PARK  or  REVERSE
only  after  the  vehicle  has  come  to  a
complete stop.
Do  not  shift  between  PARK,  REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
Before shifting into any gear, make sure
your  foot  is  firmly  pressing  the  brake
pedal.
 WARNING!
Never use the PARK position as a substi -
tute for  the parking brake. Always  apply
the parking brake fully when exiting the
vehicle  to  guard  against  vehicle  move-
ment and possible injury or damage.
Your  vehicle  could  move  and  injure  you
and others if it is not in PARK. Check by
trying  to  move  the  transmission  gear
selector  out  of  PARK  with  the  brake
pedal released. Make sure the transmis-
sion  is  in  PARK  before  exiting  the
vehicle.
The transmission may not engage PARK
if the vehicle is moving. Always bring the
vehicle  to  a  complete  stop  before
shifting  to  PARK,  and  verify  that  the
transmission  gear  position  indicator
solidly  indicates  PARK  (P)  without
blinking.  Ensure  that  the  vehicle  is
completely stopped, and the PARK posi -
tion is properly indicated, before exiting
the vehicle.

FUSES 
General Information
The  fuses  protect  electrical  systems  against
excessive current.
When  a  device  does  not  work,  you  must
check the fuse element inside the blade fuse
for a break/melt.
Also, please be aware that when using power
outlets for extended periods of time with the
engine  off  may  result  in  vehicle  battery
discharge.
 CAUTION!
Do  not  touch  the  new  bulb  with  your
fingers.  Oil  contamination  will  severely
shorten  bulb  life.  If  the  bulb  comes  in
contact  with  any  oily  surface,  clean  the
bulb with rubbing alcohol.
 WARNING!
When replacing a blown fuse, always use
an  appropriate  replacement  fuse  with
the same amp rating as the original fuse.
Never replace a fuse with another fuse of
higher amp rating. Never replace a blown
fuse with metal wires or any other mate-
rial.  Failure  to  use  proper  fuses  may
result in serious personal injury, fire and/
or property damage.
Before  replacing  a  fuse,  make sure  that
the  ignition  is  off  and  that  all  the  other
services  are  switched  off  and/or  disen -
gaged.
If the replaced fuse blows again, contact
an authorized dealer.
If  a  general  protection  fuse  for  safety
systems  (air  bag  system,  braking
system),  power  unit  systems  (engine
system,  gearbox  system)  or  steering
system  blows,  contact  an  authorized
dealer.
 CAUTION!
If  it  is  necessary  to  wash  the  engine
compartment,  take  care  not  to  directly  hit
the  fuse  box,  and  the  windshield  wiper
motors with water.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING 
Correct servicing is crucial for guaranteeing a
long  life  for  the  car  under  the  best  condi-
tions.  For  this  reason,  Jeep  has  planned  a
series  of  checks  and  services  at  fixed
distance  intervals  and,  where  provided,  at
fixed  time  intervals,  as  described  in  the
Scheduled Servicing plan. To keep the car’s
efficiency  in  tip-top  condition,  in  the
following  Scheduled  Service  plan  pages  a
few  additional  checks  are  listed  that should
be  carried  out  more  frequently  with  respect
to  the  normal  coupon redemption schedule.
Scheduled Servicing is offered by  all autho -
rized  dealerships  according  to  fixed  time  or
mileage intervals.  If,  during  each operation,
in  addition to the  ones  scheduled, the need
arises  for  further  replacements  or  repairs,
these  may  be  carried  out  with  the  owner's
explicit agreement only.
The technicians at your dealership know your
vehicle  best,  and  have  access  to  factory
trained  information,  genuine  Mopar  parts,
and  specially  designed  electronic  and
mechanical  tools  that  can  help  prevent
future  costly  repairs.  If  your  car  is  used
frequently  for  towing,  the  interval  between
one  scheduled  servicing  operation  and  the next should be reduced. More frequent main
-
tenance may be needed for vehicles in severe
operating  conditions,  such  as  dusty  areas
and very short trip driving.
NOTE:
Scheduled  Servicing  interventions  are  set
out  by  the  Manufacturer.  Failure  to  have
them  carried  out  may  invalidate  the
warranty.  It  is  advised  to  inform  an  autho -
rized dealership of any small operating irreg -
ularities without waiting for the next service.
Scheduled Servicing — Gasoline Engine  
The  oil  change  indicator  system  (if
equipped)  will  remind  you  that  it  is  time  to
take  your  vehicle  in  for  engine  oil  replace -
ment.
On  vehicles  equipped  with  instrument
cluster  display,  “Oil  Change  Required”  will
be displayed and a single chime will  sound,
indicating that an oil change is necessary.
On non-instrument cluster display equipped
vehicles,  “Change  Oil”  will  flash  in  the
instrument  cluster  odometer  and  a  single
chime  will  sound,  indicating  that  an  oil
change is necessary. The oil change indicator message will illumi
-
nate  approximately  7,000 miles
(11,200 km)  after  the  most  recent  oil
change  was  performed.  Have  your  vehicle
serviced  as  soon  as  possible,  within
500 miles (800 km). However, an earlier oil
change  at  4,500 miles  (7,500 km)  may  be
required  if  the  vehicle  is  operated  under
“Severe  Duty  Conditions”  later  in  this
section.
NOTE:
The oil change indicator message will not
monitor the time since the last oil change.
Change  your  vehicle's  oil  if  it  has  been
12 months since your last oil change even
if the oil change indicator message is NOT
illuminated.
Change  your  engine  oil  more  often  if  you
drive your vehicle off-road for an extended
period of time.
Under no circumstances should oil change
intervals  exceed  7,500 miles
(12,000 km)  or  12 months,  whichever
comes first.
An authorized dealer will reset the oil change
indicator  message  after  completing  the
scheduled oil change.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book  Page 210   

211
Once A Month Or Before A Long Trip
Check  the  engine  oil  level  about  five
minutes  after  a  fully  warmed  engine  is
shut  off.  Checking  the  oil  level  while  the
vehicle is on level ground will improve the
accuracy  of  the  oil  level  reading.  Add  oil
only when the level is at or below the ADD
or MIN mark.
Check  the  windshield  washer  solvent  and
add if required.
Check  tire  pressure  and  look  for  unusual
wear  or  damage.  Rotate  tires  at  the  first
sign of irregular wear.
Inspect the battery and clean and tighten
the terminals as required.
Check the fluid levels of coolant reservoir,
brake  master  cylinder  and  power  steering
and fill as needed.
Check all lights and other electrical items
for correct operation.At Each Oil Change
Change the engine oil filter.
Inspect the brake hoses and lines.
Inspect the CV/Universal joints.
Check  tire  pressure  and  look  for  unusual
wear  or  damage.  Rotate  tires  at  the  first
sign  of  irregular  wear,  even  if  it  occurs
before the oil indicator system turns on.
Required Maintenance Intervals
Refer  to  the  Maintenance  Plan  on  the
following pages for the required maintenance
intervals.
Maintenance Plan
NOTE:
Once you have carried out the  last interven -
tion  in  the  table,  continue  with  the  sched -
uled  servicing,  maintaining  the  frequency
indicated in the plan by marking each oper -
ation  with  a  dot  or  dedicated  note.  Simply
restarting the maintenance from the start of
the plan may cause the allowed interval to be
exceeded for some operations.
 CAUTION!
Failure  to  perform  the  required
maintenance  items  may  result  in  damage
to the vehicle.
