2016 JEEP WRANGLER engine

CAUTION!
•Skipping gears and downshifting into lower gears
at higher vehicle speeds can damage the engine
and clutch systems, Any attempt to shift into lower
gear with clutch pedal depressed may result dam-
age to the clutch system. Shifting into lower gear
and releasing the clutch may result in engine
damage.
• When descending a hill, be very careful to down-
shift one gear at a time to prevent overspeeding the
engine which can cause engine damage, and/or
clutch damage, even if the clutch pedal is pressed.
If transfer case is in low range the vehicle speeds to
cause engine and clutch damage are significantly
lower.

CAUTION! (Continued)
•Failure to follow the maximum recommended
downshifting speeds may cause the engine damage
and/or damage the clutch, even if the clutch pedal
is pressed.
• Descending a hill in low range with clutch pedal
depressed could result in clutch damage.
Maximum Recommended Downshift Speeds
CAUTION!
Failure to follow the maximum recommended down-
shifting speeds may cause the engine to overspeed
and/or damage the clutch disc, even if the clutch
pedal is pressed.

Reverse Shifting
To shift into REVERSE, bring the vehicle to a complete
stop. Press the clutch and pause briefly to allow the gear
train to stop rotating. Beginning from the NEUTRAL
position, move the shift lever in one quick, smooth
motion straight across and into the REVERSE area (the
driver will feel a firm “click” as the shifter passes the
“knock-over”). Complete the shift by pulling the shift
lever into REVERSE.
The “knock-over” provides a resistance to the driver
from accidentally entering the REVERSE shift area and warns the driver that they are about to shift the trans-
mission into REVERSE. Due to this feature, a slow shift to
REVERSE can be perceived as a high shift effort.
AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•
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.

442 STARTING AND OPERATING

CAUTION!(Continued)
•Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
WARNING!
• It is dangerous to shift out of PARK or NEUTRAL
if the engine speed is higher than idle speed. If
your foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and your foot is
firmly pressing the brake pedal.
(Continued)
WARNING! (Continued)
•Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
turn the engine OFF, and remove the ignition key.
Once the key is removed, the transmission is
locked in PARK, securing the vehicle against un-
wanted movement.
• When leaving the vehicle, always remove the igni-
tion key from the vehicle and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be

WARNING!(Continued)
warned not to touch the parking brake, brake pedal
or the transmission gear selector.
• Do not leave the ignition key in or near the vehicle
(or in a location accessible to children). A child
could operate power windows, other controls, or
move the vehicle.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the ignition switch can be turned to the LOCK/
OFF (key removal) position. The key can only be re-
moved from the ignition when the ignition is in the
LOCK/OFF position, and once removed the transmission
is locked in PARK. NOTE:
If a malfunction occurs, the system will trap the
key in the ignition switch to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key cannot be removed until you obtain
service.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in PARK
unless the brakes are applied. To shift the transmission
out of PARK, the ignition switch must be turned to the
ON/RUN position (engine running or not) and the brake
pedal must be pressed.
444 STARTING AND OPERATING

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
NOTE:
•After selecting any gear range, wait a moment to allow
the selected gear to engage before accelerating. This is
especially important when the engine is cold.
• If there is a need to restart the engine, be sure to cycle
the ignition to the LOCK/OFF position before restart-
ing. Transmission gear engagement may be delayed
after restarting the engine if the ignition is not cycled
to the LOCK/OFF position first.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range. Never attempt to use PARK while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK, otherwise the load on
the transmission locking mechanism may make it diffi-
cult to move the shift lever out of PARK. As an added
precaution, turn the front wheels toward the curb on a
downhill grade and away from the curb on an uphill
grade.
NOTE:
On four-wheel drive vehicles be sure that the
transfer case is in a drive position.
446 STARTING AND OPERATING

WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked 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
gear selector/shift lever out of PARK with the brake
pedal released. Make sure the transmission is in
PARK before leaving the vehicle.

locked in PARK, securing the vehicle against un-
wanted movement.
• When leaving the vehicle, always remove the igni-
tion key from the vehicle and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the gear selector.
• Do not leave the ignition key in or near the vehicle
(or in a location accessible to children). A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
• Before moving the gear selector/shift lever out of
PARK, you must turn the ignition switch from the
LOCK/OFF position to the ON/RUN position, and
also press the brake pedal. Otherwise, damage to
the gear selector/shift lever could result.
• DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as this
can damage the drivetrain.
The following indicators should be used to ensure that
you have engaged the transmission into the PARK posi-
tion (P):
• When shifting into PARK, firmly move the shift lever
all the way forward and to the left until it stops and is
fully seated.
448 STARTING AND OPERATING

•Look at the transmission gear position display and
verify that it indicates the PARK position (P).
• With brake pedal released, verify that the shift lever
will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Apply the parking brake and shift
the transmission into PARK if you must leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
