automatic transmission JEEP COMPASS 2016 1.G User Guide

Downshifting
Proper downshifting will improve fuel economy and
prolong engine life.
CAUTION!
If you skip a gear while downshifting or downshift
at too high of a vehicle speed, these conditions may
cause the engine to overspeed if too low of a gear is
selected and the clutch pedal is released. Damage to
the clutch and the transmission can result from
skipping a gear while downshifting or downshifting
at too high of a vehicle speed even if the clutch pedal
is held pressed (i.e., not released).
To maintain a safe speed and prolong brake life, shift
down to second or first gear when descending a steep
grade. When turning a corner or driving up a steep grade,
downshift early so that the engine will not be overbur-
dened.
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, 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.5
STARTING AND OPERATING 343

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.
Six-Speed Automatic Transmission — If Equipped
The transmission gear 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 Inter-
lock 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).

STARTING AND OPERATING 345

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.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through underdrive first, second,
third, and fourth gears, direct fifth gear and overdrive
sixth gear. The DRIVE position provides optimum driv-
ing characteristics under all normal operating conditions.
5
STARTING AND OPERATING 349

When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the AutoStick shift
control (refer to “AutoStick (Six-Speed Automatic Trans-
mission)” in this section for further information) to select
a lower gear. Under these conditions, using a lower gear
will improve performance and extend transmission life
by reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal operat-
ing limits, the transmission controller will modify the
transmission shift schedule and expand the range of
torque converter clutch engagement. This is done to
prevent transmission damage due to overheating. If the
transmission becomes extremely hot, the “Transmission
Temperature Warning Light” may illuminate and the
transmission may operate differently until the transmis-
sion cools down.During very cold temperatures (-4°F [-20°C] or below),
transmission operation may be modified depending on
engine and transmission temperature as well as vehicle
speed. Normal operation will resume once the transmis-
sion temperature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in fourth gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will continue
to operate. The Malfunction Indicator Light (MIL) may be
illuminated. Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service without dam-
aging the transmission.
350 STARTING AND OPERATING

In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur. If the transmission cannot be reset, authorized dealer
service is required.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (sixth gear). The transmission will
automatically shift into Overdrive if the following con-
ditions are present:
•
The shift lever is in the DRIVE position.
• The transmission fluid has reached an adequate tem-
perature.
• The engine coolant has reached an adequate tempera-
ture.
• The vehicle speed is sufficiently high.
• The driver is not heavily pressing the accelerator.
5
STARTING AND OPERATING 351

Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
some accelerations, the clutch automatically disengages.
NOTE:Engagement of the torque converter clutch is
inhibited at very cold temperatures. Because the engine
speed is higher when the torque converter clutch is not
engaged, it may seem as if the transmission is not shifting
into Overdrive when cold. This is normal. The torque
converter clutch will function normally once the trans-
mission is sufficiently warm.
Continuously Variable Automatic Transmission
(CVT) — If Equipped
The transmission gear 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 Inter-
lock System” in this section). To drive, move the shift
lever from PARK or NEUTRAL to the DRIVE position.
NOTE: The Continuously Variable Automatic Transmis-
sion (CVT) changes ratios in a continuous manner. This
may sometimes feelas if it is slipping, but this is normal
and does not harm anything.
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
shifting between these gears.
352 STARTING AND OPERATING

further information) to select a lower gear ratio. Under
these conditions, using a lower gear ratio will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup.During sustained high speed driving or trailer
towing up long grades on hot days, the auto-
matic transmission oil may become too hot. If
this happens, the transmission overheat indica-
tor light will come on, and the vehicle will slow slightly
until the transmission cools down enough to allow a
return to the requested speed. This is done to prevent
transmission damage due to overheating. If the high
speed is maintained, the overheating may reoccur, as
before, in a cyclic fashion. LOW (L) — If Equipped
Use this range for engine braking when descending very
steep grades. In this range, the transmission will down-
shift for maximum engine braking, and upshifts will
occur only to prevent engine overspeed.
AUTOSTICK
AutoStick (Six-Speed Automatic Transmission)
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This system
can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
5
STARTING AND OPERATING 357

Operation
When the shift lever is in the DRIVE position, the
transmission will operate automatically, shifting between
the six available gears. To engage AutoStick, simply tap
the shift lever to the right or left (+/-) while in the DRIVE
position. Tapping (-) to enter AutoStick mode will down-
shift the transmission to the next lower gear, while using
(+) to enter AutoStick mode will retain the current gear.
When AutoStick is active, the current transmission gear is
displayed in the instrument cluster.
In AutoStick mode, the transmission will shift up or
down when the driver moves the shift lever to the right
(+) or left (-), unless an engine lugging or overspeed
condition would result. It will remain in the selected gear
until another upshift or downshift is chosen, except as
described below:
•The transmission will automatically upshift when nec-
essary to prevent engine over-speed. •
The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
• The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
• You can start out, from a stop, in first or second gear.
Tapping (+) (at a stop) will allow starting in second
gear. Starting out in second gear can be helpful in
snowy or icy conditions.
• If a requested downshift would cause the engine to
overspeed, that shift will not occur.
• Avoid using speed control when AutoStick is engaged.
• Transmission shifting will be more noticeable when
AutoStick is engaged.
358 STARTING AND OPERATING

•The system may revert to automatic shift mode if a
fault or overheat condition is detected.
To disengage AutoStick mode, hold the shift lever to the
right (+) until “D” is once again displayed in the instru-
ment cluster. You can shift in or out of the AutoStick
mode at any time without taking your foot off the
accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
AutoStick (CVT) — If Equipped
AutoStick is a driver-interactive transmission feature
providing six manually selectable gear ratios, giving you
more control of the vehicle. AutoStick allows you to maximize engine braking, eliminate undesirable upshifts
and downshifts, and improve overall vehicle perfor-
mance. This system can also provide you with more
control during passing, city driving, cold slippery condi-
tions, mountain driving, trailer towing, and many other
situations.
Operation
NOTE:
AutoStick is not available until the CVT warms
up in cold weather.
When the shift lever is in the DRIVE position, AutoStick
is activated by moving the shift lever side-to-side. Mov-
ing the shift lever to the right (+) will activate AutoStick
and shift up to the next higher manual ratio, unless you
are already operating in or near Overdrive, in which case
sixth gear ratio will be selected. In like manner, moving
the shift lever to the left (-) will activate AutoStick and
shift to the next lower manual ratio. The manually-
selected gear will be displayed in the instrument cluster.5
STARTING AND OPERATING 359

In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver,
unless an engine lugging or overspeed condition would
result. It will remain in the selected gear until another
upshift or downshift is chosen, except as described
below:
•The transmission will automatically upshift when nec-
essary to prevent engine over-speed.
• The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
• The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
• If a requested downshift would cause the engine to
overspeed, that shift will not occur. •
Transmission shifting will be more noticeable when
AutoStick is engaged.
• Heavy Anti-Lock Brake System (ABS) application will
disengage AutoStick mode.
• The system may revert to automatic shift mode if a
fault or overheat condition is detected.
To disengage AutoStick mode, hold the shift lever to the
right (+) until “D” is once again displayed in the instru-
ment cluster. You can shift in or out of the AutoStick
mode at any time without taking your foot off the
accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
