2017 JEEP WRANGLER heater

To Raise The Rear Seat
Raise the seatback and lock it into place. If interference
from the cargo area prevents the seatback from fully
locking, you will have difficulty returning the seat to its
proper position.
NOTE:If the rear seatback is not fully latched, the center
shoulder belt will not be able to be extended for use. If you
cannot extend the center shoulder belt, make sure your
seatback is fully latched.
WARNING!
Be certain that the seatback is securely locked into
position. If the seatback is not securely locked into
position the seat will not provide the proper stability
for child seats and/or passengers. An improperly
latched seat could cause serious injury.
Heated Seats — If Equipped
On some models, the front driver and passenger seats may
be equipped with heaters in both the seat cushions and
seatbacks. There are two heated seat switches that allow the driver
and passenger to operate the seats independently. The
controls for each seat are located on a switch bank near the
bottom center of the instrument panel.
You can choose from HI, LO or OFF heat settings. Amber
indicator lights in each switch indicate the level of heat in
use. Two indicator lights will illuminate for HI, one for LO
and none for OFF.
Push the switch once to select HI-level heating.
Push the switch a second time to select LO-level
heating. Push the switch a third time to shut the
heating elements OFF.
When the HI-level setting is selected, the heater will
provide a boosted heat level during the initial stages of
operation. Then, the heat output will drop to the normal
HI-level. If the HI-level setting is selected, the system will
automatically switch to LO-level after approximately 30
minutes of continuous operation. At that time, the number
of illuminated LEDs changes from two to one, indicating
the change. The LO-level setting will turn OFF automati-
cally after approximately 30 minutes.

NOTE:When a heat setting is selected, heat will be felt
within two to five minutes.
WARNING!
• Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns even
at low temperatures, especially if used for long
periods of time
• Do not place anything on the seat or seatback that
insulates against heat, such as a blanket or cushion.
This may cause the seat heater to overheat. Sitting in
a seat that has been overheated could cause serious
burns due to the increased surface temperature of the
seat.
HEAD RESTRAINTS
Head restraints are designed to reduce the risk of injury by
restricting head movement in the event of a rear impact.
Head restraints should be adjusted so that the top of the
head restraint is located above the top of your ear.
WARNING!
• All occupants, including the driver, should not oper-
ate a vehicle or sit in a vehicle’s seat until the head
restraints are placed in their proper positions in
order to minimize the risk of neck injury in the event
of a crash.
• Head restraints should never be adjusted while the
vehicle is in motion. Driving a vehicle with the head
restraints improperly adjusted or removed could
cause serious injury or death in the event of a
collision.
Front Head Restraints
To raise the head restraint, pull upward on the head
restraint. To lower the head restraint, push the adjustment
button located on the base of the head restraint, and push
downward on the head restraint.
To remove the head restraint, raise it as far as it can go then
push the adjustment button and the release button at the
base of each post while pulling the head restraint up. To
reinstall the head restraint, put the head restraint posts into
the holes and push downward. Then adjust it to the
appropriate height.
46 GETTING TO KNOW YOUR VEHICLE

CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear win-
dow. Do not use abrasive window cleaners on the
interior surface of the window. Use a soft cloth and a
mild washing solution, wiping parallel to the heat-
ing elements. Labels can be peeled off after soaking
with warm water.
• Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the win-
dow.
• Keep all objects a safe distance from the window.
Manual Operation Override
This system offers a full complement of manual override
features. The AUTO symbol in the front ATC display will
be turned off when the system is being used in the manual
mode.
NOTE: The system will not automatically sense the pres-
ence of fog, mist or ice on the windshield. Defrost mode
must be manually selected to clear the windshield and side
glass.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Use of the air Recirculation mode during
Winter months is not recommended, because it may cause
window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service (i.e.,
vacation) for two weeks or more, run the air conditioning
system at idle for about five minutes, in fresh air with the
blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.

externally powered electric engine block heater (available
from your authorized dealer) is recommended.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
•
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic transmis-
sion cannot be started this way. Unburned fuel could
enter the catalytic converter and once the engine has
started, ignite and damage the converter and vehicle.
(Continued)
WARNING! (Continued)
•If the vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster battery
or the battery in another vehicle. This type of start
can be dangerous if done improperly. Refer to
“Jump-Starting Procedure” in “In Case Of Emer-
gency” for further information.
Without Tip Start — Manual Transmission Only
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather” procedures,
it may be flooded. Push the accelerator pedal all the way to
the floor and hold it there while cranking the engine. This
should clear any excess fuel in case the engine is flooded.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to 15
seconds before trying again.
286 STARTING AND OPERATING

If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key is
released. If this occurs, continue cranking with the accel-
erator pedal pushed all the way to the floor. Release the
accelerator pedal and the key once the engine is running
smoothly.
If the engine shows no sign of starting after two 15-second
periods of cranking with the accelerator pedal held to the
floor, repeat the “Normal Starting” or “Extreme Cold
Weather” procedures.
With Tip Start — Automatic Transmission Only
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather” procedures,
it may be flooded. To clear any excess fuel, push the
accelerator pedal all the way to the floor and hold it. Then,
turn the ignition switch to the START position and release
it as soon as the starter engages. The starter motor will
disengage automatically in 10 seconds. Once this occurs,
release the accelerator pedal, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.CAUTION!
To prevent damage to the starter, wait 10 to 15 seconds
before trying again.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a grounded,
three-wire extension cord.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
The engine block heater cord is found under the hood
bundled in front of the battery tray.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt AC electri-
cal cord could cause electrocution.
