2013 JEEP WRANGLER UNLIMITED Owners Manual

Shifting
Fully press the clutch pedal before shifting gears. As you
release the clutch pedal, lightly press the accelerator
pedal.
You should always use first gear when starting from a
standing position.
Recommended Vehicle Shift Speeds
To utilize your manual transmission efficiently for both
fuel economy and performance, it should be upshifted as
listed in recommended shift speed chart. Shift at the
vehicle speeds listed for acceleration. When heavily
loaded or pulling a trailer these recommended up-shift
speeds may not apply.

Downshifting
Moving from a high gear down to a lower gear is
recommended to preserve brakes when driving down
steep hills. In addition, downshifting at the right time
provides better acceleration when you desire to resume
speed. Downshift progressively. Do not skip gears to
avoid overspeeding the engine and clutch.
WARNING!Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip, and the vehicle could skid. CAUTION!When descending a hill, be very careful to downshift
one gear at a time to prevent overspeeding the engine
which can cause valve damage, and/or clutch disc
damage, even if the clutch pedal is pressed.
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.416 STARTING AND OPERATING

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” prevents the driver from accidentally
entering the REVERSE shift area and warns the driver
that they are about to shift the transmission into RE-
VERSE. 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 PARK only after the vehicle has come to
a complete stop.
• Shift into or out of REVERSE only after the vehicle
has come to a complete stop and the engine is at
idle speed.
• Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
• 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!• 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,
and remove the ignition key. Once the ignition key
is removed, the shift lever is locked in PARK,
securing the vehicle against unwanted movement.
• When leaving the vehicle, always remove the key
fob from the ignition key and lock your 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 (Continued)418 STARTING AND OPERATING

WARNING! (Continued)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 shift lever. Do not leave the ignition key in or
near the vehicle. A child could operate power
windows, other controls, or move the vehicle.
• It is dangerous to move the shift lever 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 reverse. 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. Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
before the ignition switch can be turned to the LOCK/
OFF position. The key can only be removed from the
ignition when the ignition is in the LOCK/OFF position
and once removed the shift lever is locked in PARK.
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 move the shift lever 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.
5 STARTING AND OPERATING 419

Five-Speed Automatic Transmission
The shift lever position display (located in the instrument
cluster) indicates the transmission gear range. You must
press the brake pedal to move the shift lever out of PARK
(refer to “Brake/Transmission Shift Interlock System” in
this section). To drive, move the shift lever from PARK or
NEUTRAL to the DRIVE position.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers). Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when
moving the shift lever between these gears.
The transmission shift lever has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual down-
shifts can be made using the Electronic Range Select
(ERS) shift control (refer to “Electronic Range Select (ERS)
Operation” in this section). Moving the shift lever to the
left or right (-/+) while in the DRIVE position will select
the highest available transmission gear, and will display
that gear in the instrument cluster as 4, 3, 2, 1.420 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.
PARK
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 place the shift
lever in PARK first, and then apply the parking brake.
When parking on a hill, apply the parking brake before
placing the shift lever in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.Shift Lever
5 STARTING AND OPERATING 421

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 completely in PARK. Check by trying to
move the shift lever rearward (with the brake pedal
released), after you have placed it in PARK. Make
sure the transmission is in PARK before leaving
the vehicle.
• It is dangerous to move the shift lever 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 reverse. You could lose control of the
vehicle and hit someone or something. Only shift (Continued) WARNING! (Continued)into gear when the engine is idling normally and
