Jeep Wrangler: STARTING AND OPERATING / STOP/START SYSTEM — MANUAL TRANSMISSION (IF EQUIPPED)
The Engine Stop/Start (ESS) function is
developed to reduce fuel consumption. The
system will stop the engine automatically during
a vehicle stop if the required conditions are
met. Pressing the clutch pedal will
automatically restart the vehicle.
ESS vehicles have been upgraded with a heavy
duty starter, enhanced battery, and other
upgraded engine parts, to handle the additional
engine starts. Vehicles equipped with eTorque
contain a heavy duty motor generator and an
additional hybrid electric battery to store energy
from vehicle deceleration for use on engine
startup after a stop as well as providing launch
torque assist.
NOTE:
It is recommended that Stop/Start be disabled
during off-road use.
Secondary Battery
Your vehicle may be equipped with a secondary
battery used to power the Stop/Start system
and the 12 Volt vehicle electrical system. The
secondary battery is located behind the wheel
well for the front passenger wheel.

Battery Locations
- Primary Battery
- Secondary Battery
If there is a malfunction in the Stop/Start
system, the system will not shut down the
engine. A “SERVICE STOP/START SYSTEM”
message will appear in the instrument cluster
display...
WARNING!
Vehicles with the Stop/Start system will be
equipped with two batteries. Both the main
and the supplemental batteries must be
disconnected to completely de-energize the
12 Volt electrical system...
Other information:
Automatic Operation
Push the AUTO button on the faceplate, or
the AUTO button on the touchscreen on the
Automatic Temperature Control (ATC)
Panel.
Next, adjust the temperature that you would

buttons...
Children who are large enough to wear the
shoulder belt comfortably, and whose legs are
long enough to bend over the front of the seat
when their back is against the seatback, should
use the seat belt in a rear seat. Use this simple
5-step test to decide whether the child can use
the vehicle’s seat belt alone:
Can the child sit all the way back against
the back of the vehicle seat?
Do the child’s knees bend comfortably over
the front of the vehicle seat – while the child
is still sitting all the way back?
Does the shoulder belt cross the child’s
shoulder between the neck and arm?
Is the lap part of the belt as low as possible,
touching the child’s thighs and not the
stomach?
Can the child stay seated like this for the
whole trip?
If the answer to any of these questions was
“no”, then the child still needs to use a booster
seat in this vehicle...
