2018 JEEP WRANGLER JK heater

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.

GETTING TO KNOW YOUR VEHICLE 39

Cycle the ignition switch to the START position and release
when the engine starts. If the engine fails to start within 10
seconds, cycle the ignition switch to the LOCK/OFF posi-
tion, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
Extreme Cold Weather (Below –22°F Or 30°C)
To ensure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
If Engine Fails To Start

CAUTION!(Continued)
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on HOT
(H), and you hear continuous chimes, turn the engine
off immediately and call for service.
NOTE: There are steps that you can take to slow down an
impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine cooling system.
