GETTING TO KNOW YOUR INSTRUMENT PANEL51
Door Open Warning Light
This indicator will illuminate when one
or more door(s) are not fully closed.
NOTE:
If the vehicle is moving and a door is opened,
there will also be a single chime.
Electronic Throttle Control (ETC) Warning
Light
This warning light will illuminate to
inform of a problem with the ETC
system. If a problem is detected while
the vehicle is running, the light will
either stay on or flash depending on the nature
of the problem. Cycle the ignition when the
vehicle is safely and completely stopped and
the transmission is placed in the PARK (P)
position. The light should turn off. If the light
remains on with the vehicle running, your
vehicle will usually be drivable; however, see an
authorized dealer for service as soon as
possible. If the light continues to flash when the vehicle is
running, immediate service is required and you
may experience reduced performance, an
elevated/rough idle, or engine stall and your
vehicle may require towing. The light will come
on when the ignition is placed in the ON/RUN or
MAR/ON/RUN position and remain on briefly as
a bulb check. If the light does not come on
during starting, have the system checked by an
authorized dealer.Engine Coolant Temperature Warning Light
This warning light warns of an
overheated engine condition. If the
engine coolant temperature is too
high, this indicator will illuminate and
a single chime will sound. If the temperature
reaches the upper limit, a continuous chime will
sound for four minutes or until the engine is
able to cool, whichever comes first.
If the light turns on while driving, safely pull over
and stop the vehicle. If the Air Conditioning
(A/C) system is on, turn it off. Also, shift the
transmission into NEUTRAL (N) and idle the
vehicle. If the temperature reading does not
return to normal, turn the engine off
immediately and call for service Ú page 207.
Oil Pressure Warning Light
This warning light will illuminate to
indicate low engine oil pressure. If the
light turns on while driving, stop the
vehicle, shut off the engine as soon as
possible, and contact an authorized dealer. A
chime will sound when this light turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how
much oil is in the engine. The engine oil level
must be checked under the hood.
Transmission Temperature Warning Light — If
Equipped
This warning light will illuminate to
warn of a high transmission fluid
temperature. This may occur with
strenuous usage such as trailer
towing. If this light turns on, stop the vehicle and
run the engine at idle or slightly faster, with the
transmission in PARK (P) or NEUTRAL (N), until
the light turns off. Once the light turns off, you
may continue to drive normally.

52GETTING TO KNOW YOUR INSTRUMENT PANEL
Seat Belt Reminder Warning Light
When the ignition is first placed in the
ON/RUN or MAR/ON/RUN position, if
the driver’s seat belt is unbuckled, a
chime will sound and the light will turn
on. When driving, if the driver or front passenger
seat belt remains unbuckled, the Seat Belt
Reminder Light will flash or remain on
continuously and a chime will sound
Ú page 153.
Transmission Fault Warning Light
This light will illuminate (together with
a message in the instrument cluster
display and a buzzer) to indicate a
transmission fault. Contact an
authorized dealer if the message remains after
restarting the engine.
Engine Oil Level Warning Light
This warning light appears on the
panel when the engine oil level falls
below the minimum recommended
value. Restore the correct engine oil
level or contact your authorized dealer for
service.
Yellow Warning Lights
Anti-Lock Brake System (ABS) Warning Light
This light monitors the ABS. The light
will turn on when the ignition is placed
in the ON/RUN or MAR/ON/RUN
position and may stay on for as long
as four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the brake
system is not functioning and service is
required. However, the conventional brake system will continue to operate normally if the
brake warning light is not on.
If the ABS light is on, the brake system should
be serviced as soon as possible to restore the
benefits of Anti-Lock Brakes. If the ABS light
does not turn on when the ignition is placed in
the ON/RUN or MAR/ON/RUN position, have
the light inspected by an authorized dealer.
Low Fuel Warning Light
When the fuel level reaches
approximately 2–3 gal (9–11 L) this
light will turn on, and remain on until
fuel is added.
Generic Warning Light
The Generic Warning Light will
illuminate if any of the following
conditions occur: Engine Oil Pressure
Sensor Failure, External Light Failure,
Parking Sensor Failure, Fuel Cut-Off Fail/
Intervention, Generic Failure on Trailer, or Air
Bag telltale recovery.
The telltale will blink in case of an Air Bag
Warning Light Failure. Contact an authorized
dealer immediately for service.
WARNING!
If you continue operating the vehicle when
the Transmission Temperature Warning Light
is illuminated you could cause the fluid to boil
over, come in contact with hot engine or
exhaust components and cause a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated will
eventually cause severe transmission
damage or transmission failure.

21_VM_OM_EN_USC_t.book Page 52

66STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest
upshifts and downshifts, and the best fuel
economy. The transmission automatically
upshifts through all forward gears.
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain,
traveling into strong head winds, or while towing
a heavy trailer), use the Electronic Range Select
(ERS) shift control to select a lower gear range
Úpage 67. Under these conditions, using a
lower gear range will improve performance and
extend transmission life by reducing excessive
shifting and heat buildup.
If the transmission temperature exceeds
normal operating limits, the transmission
controller may modify the transmission shift
schedule, reduce engine torque, and/or 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 transmission cools down. During cold temperatures, transmission
operation may be modified depending on
engine and transmission temperature as well
as vehicle speed. This feature improves warm
up time of the engine and transmission to
achieve maximum efficiency. Engagement of
the torque converter clutch, and shifts into
8th or 9th gear, are inhibited until the
transmission fluid is warm Ú
page 67. Normal
operation will resume once the transmission
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 may operate only in a fixed gear,
or may remain in NEUTRAL. The Malfunction
Indicator Light (MIL) may be illuminated. Limp
Home Mode may allow the vehicle to be driven
to an authorized dealer for service without
damaging the transmission. 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 OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the
transmission will return to normal
operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit an authorized dealer
at your earliest possible convenience. An autho -
rized dealer has diagnostic equipment to
assess the condition of your transmission. If the
transmission cannot be reset, authorized dealer
service is required.

21_VM_OM_EN_USC_t.book Page 66

STARTING AND OPERATING67
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 automatically 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:
The torque converter clutch will not engage until
the transmission fluid is warm [usually after 1 to
3 miles (2 to 5 km) of driving]. Because the
engine speed is higher when the torque
converter clutch is not engaged, it may seem as
if the transmission is not shifting properly when
cold. This is normal. The torque converter clutch
will function normally once the transmission is
sufficiently warm.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear. For example, if you set the transmission
gear limit to fifth gear, the transmission will not
shift above fifth gear, but will shift through the
lower gears normally. You can switch between DRIVE and ERS mode
at any vehicle speed. When the gear selector is
in the DRIVE position, the transmission will
operate automatically, shifting between all
available gears.
Moving the gear selector to the ERS position
(beside DRIVE) will activate ERS mode, display
the current gear in the instrument cluster, and
set that gear as the top available gear. Once in
ERS mode, moving the gear selector forward (-)
or rearward (+) will change the top available
gear, which will be displayed in the instrument
cluster.
To exit ERS mode, simply return the gear
selector to the DRIVE position.
NOTE:
To select the proper gear position for maximum
deceleration (engine braking), move the gear
selector into the ERS position, then simply press
and hold it forward (-). The transmission will
shift to the range from which the vehicle can
best be slowed down.
POWER STEERING
The standard power steering system will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will provide mechanical steering capability if
power assist is lost.
If for some reason the power assist is
interrupted, it will still be possible to steer your
vehicle. Under these conditions, you will
observe a substantial increase in steering
effort, especially at very low vehicle speeds and
during parking maneuvers.
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.

Shallow Standing Water
Although your vehicle is capable of driving
through shallow standing water, consider the
following Cautions and Warnings before doing
so.
WARNING!
Driving through standing water limits your
vehicle’s traction capabilities. Do not
exceed 5 mph (8 km/h) when driving
through standing water.
Driving through standing water limits your
vehicle’s braking capabilities, which
increases stopping distances. Therefore,
after driving through standing water, drive
slowly and lightly press on the brake pedal
several times to dry the brakes.
Failure to follow these warnings may result
in injuries that are serious or fatal to you,
your passengers, and others around you.
CAUTION!
Always check the depth of the standing
water before driving through it. Never drive
through standing water that is deeper than
the bottom of the tire rims mounted on the
vehicle.
Determine the condition of the road or the
path that is under water and if there are any
obstacles in the way before driving through
the standing water.
Do not exceed 5 mph (8 km/h) when
driving through standing water. This will
minimize wave effects.
Driving through standing water may cause
damage to your vehicle’s drivetrain compo -
nents. Always inspect your vehicle’s fluids
(i.e., engine oil, transmission, axle, etc.) for
signs of contamination (i.e., fluid that is
milky or foamy in appearance) after driving
through standing water. Do not continue to
operate the vehicle if any fluid appears
contaminated, as this may result in further
damage. Such damage is not covered by
the New Vehicle Limited Warranty.
Getting water inside your vehicle’s engine
can cause it to lock up and stall out, and
cause serious internal damage to the
engine. Such damage is not covered by the
New Vehicle Limited Warranty.
CAUTION! (Continued)

SERVICING AND MAINTENANCE231
(Continued)
Brake Master Cylinder
The fluid in the master cylinder should be
checked when performing under hood services
or immediately if the “Brake Warning Light” is
illuminated.
Be sure to clean the top of the master cylinder
area before removing the cap. If necessary, add
fluid to bring the fluid level up to the
requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. Brake
fluid level should be checked when pads are
replaced. However, low fluid level may be
caused by a leak and a checkup may be
needed. Use only FCA recommended brake fluid
Ú page 261.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission
fluid to ensure optimum transmission
performance and life. Use only FCA specified
transmission fluid Ú page 261. It is important
to maintain the transmission fluid at the correct
level using the recommended fluid.
NOTE:
No chemical flushes should be used in any
transmission; only the approved lubricant
should be used.
WARNING!
Use only FCA recommended brake fluid
Ú page 261. Using the wrong type of brake
fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory
installed hydraulic master cylinder reser -
voir.
To avoid contamination from foreign matter
or moisture, use only new brake fluid or
fluid that has been in a tightly closed
container. Keep the master cylinder reser -
voir cap secured at all times. Brake fluid in
an open container absorbs moisture from
the air resulting in a lower boiling point. This
may cause it to boil unexpectedly during
hard or prolonged braking, resulting in
sudden brake failure. This could result in a
collision.
Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces; care should be taken to
avoid its contact with these surfaces.
Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
WARNING! (Continued)
CAUTION!
Using a transmission fluid other than FCA
recommended fluid may cause deterioration
in transmission shift quality and/or torque
converter shudder Ú page 261.
