Defrost Mode

Air comes from the windshield and side
window demist outlets. When the defrost
button is selected, the blower level may
increase. Use Defrost mode with maximum
temperature settings for best windshield and side
window defrosting and defogging. When toggling the
front defrost mode button, the Climate Control system
will return to the previous setting.

Mix Mode
Air is directed through the floor, defrost,
and side window demister outlets.
This setting works best in cold or snowy
conditions that require extra heat to the
windshield. This setting is good for maintaining
comfort while reducing moisture on the
windshield.

Additional Rear Climate Controls Switches

Rear Blower Control

Push this button to turn on the rear climate
controls. An indicator light will turn on when
the rear climate control is on.

OPERATING TIPS
Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected with
a high-quality antifreeze coolant to provide proper
corrosion protection and to protect against engine
overheating. A solution of 50% OAT (Organic
Additive Technology) coolant that meets the
requirements of FCA Material Standard MS.90032
and 50% water is recommended Ú page 251.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling
system is functioning properly and the proper
amount, type, and concentration of coolant is
used. Use of the air Recirculation mode during
Winter months is not recommended because it
may cause window fogging.
Vacation Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Úpage 243.

Odometer/Trip Odometer Display Area

US Federal regulations require that upon
transfer of vehicle ownership, the seller certify
to the purchaser the correct mileage that the
vehicle has been driven. If your odometer needs
to be repaired or serviced, the repair technician
should leave the odometer reading the same as
it was before the repair or service. If the techni -
cian cannot do so, then the odometer must be
set at zero, and a sticker must be placed in the
door jamb stating what the mileage was before
the repair or service. It is a good idea for you to
make a record of the odometer reading before
the repair/service, so that you can be sure that
it is properly reset, or that the door jamb sticker
is accurate if the odometer must be reset at
zero.

The light also will turn on when the parking brake
is applied with the ignition switch in the ON/RUN
position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake
application.
Battery Charge Warning Light
This warning light will illuminate when the
battery is not charging properly. If it stays
on while the engine is running, there may
be a malfunction with the charging
system. Contact an authorized dealer as soon as
possible.
This indicates a possible problem with the
electrical system or a related component.

This warning light will turn on when
there's a fault with the EPS system
Ú page 78.
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 Temperature Warning Light
This 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 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
and idle the vehicle. If the temperature reading does
not return to normal, turn the engine off immediately
and call for service
Ú
page 194.

Hood Open Warning Light
The telltale turns on when the hood is not
properly closed. Along with the icon, an
image of the vehicle with an open hood
cap appears on the display.
Close the hood properly.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.

22_VF_OM_EN_USC_t.book Page 60

78STARTING AND OPERATING
NOTE:To select the proper gear position for maximum
deceleration (engine braking), move the gear
selector into the ERS position, then tap it forward
“-” repeatedly as the vehicle slows. The trans -
mission will shift to the range from which the
vehicle can best be slowed down.
When To Use TOW/HAUL Mode

When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting
occurs, push the TOW/HAUL switch to activate
TOW/HAUL mode. This will improve performance and
reduce the potential for transmission overheating or
failure due to excessive shifting. When operating in
TOW/HAUL mode, transmission upshifts are delayed,
and the transmission will automatically downshift (for
engine braking) during steady braking maneuvers.

The “TOW/HAUL Indicator Light” will illuminate in
the instrument cluster to indicate that TOW/HAUL
mode has been activated. Pushing the switch a
second time restores normal operation. Normal
operation is always the default at engine start-up. If TOW/HAUL mode is desired, the switch must be
pushed each time the engine is started.
POWER STEERING
The electric power steering system will provide
increased vehicle response and ease of
maneuverability. The power steering system
adapts to different driving conditions.
If the steering icon is flashing, it indicates that the
vehicle needs to be taken to the dealer for service.
It is likely the vehicle has lost power steering
assistance.
If the steering icon is displayed and the “POWER
STEERING SYSTEM OVER TEMP” message is
displayed on the instrument cluster screen, this
indicates an over temperature condition in the
power steering system. Once driving conditions are
safe, pull over and let the vehicle idle for a few
moments until the icon and message turn off
Ú
page 55. If the steering icon is displayed and the “SERVICE
POWER STEERING – ASSIST OFF” message is
displayed on the instrument cluster screen, this
indicates the vehicle needs to be taken to the
dealer for service Ú
page 55.NOTE:

Even if the power steering system is no longer
operational, it is still possible to steer the vehicle.
Under these conditions there will be a substantial
increase in steering effort, especially at low
speeds and during parking maneuvers.

If the condition persists, see an authorized
dealer for service.

86STARTING AND OPERATING
NOTE:
If your vehicle is at standstill longer than two
seconds, the driver will either have to push the
RES (resume) button, or apply the accelerator
pedal to reengage the Adaptive Cruise Control
(ACC) to the existing set speed.
ACC cannot be resumed if there is a stationary
vehicle in front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set
speed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button. U.S. Speed (mph)
Pushing the SET (+)
, or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.

If the button is continually pushed, the set speed
will continue to adjust in 5 mph increments until
the button is released. The new set speed is
reflected in the instrument cluster display.

Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.

If the button is continually pushed, the set speed
will continue to adjust in 10 km/h increments
until the button is released. The new set speed is
reflected in the instrument cluster display.

NOTE:When you override and push the SET (+) button or
SET (-) button, the new set speed will be the current
speed of the vehicle.
When ACC Is Active

When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the vehicle.

The ACC system decelerates the vehicle to a full
stop when following the vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
after two seconds the driver will either have to
push the RES (resume) button, or apply the
accelerator pedal to reengage the ACC to the
existing set speed.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal.
In addition, downshifting may occur while
climbing uphill or descending downhill. This is
normal operation and necessary to maintain set
speed. When driving uphill and downhill, the
ACC system will cancel if the braking tempera -
ture exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set
by varying the distance setting between four bars
(longest), three bars (long), two bars (medium) and
one bar (short). Using this distance setting and
the vehicle speed, ACC calculates and sets the
distance to the vehicle ahead. This distance
setting will show in the instrument cluster display.
WARNING!

The Resume function should only be used if traffic
and road conditions permit. Resuming a set speed
that is too high or too low for prevailing traffic and
road conditions could cause the vehicle to
accelerate or decelerate too sharply for safe
operation. Failure to follow these warnings can result
in a collision and death or serious personal injury.

22_VF_OM_EN_USC_t.book Page 86

116STARTING AND OPERATING
Automatic Transmission

The DRIVE range can be selected when towing.
The transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, select
TOW/HAUL mode or select a lower gear range (using
the Electronic Range Select (ERS) shift control).

NOTE:Using TOW/HAUL mode or selecting a lower gear
range (using the ERS shift control) while operating
the vehicle under heavy loading conditions will
improve performance and extend transmission life
by reducing excessive shifting and heat buildup.
This action will also provide better engine braking. When towing a loaded trailer up steep grades at
low speeds, holding your vehicle in FIRST gear
(using the ERS shift control) can help to avoid
transmission overheating.
Tow/Haul Mode
To reduce potential for automatic transmission
overheating, activate TOW/HAUL mode when
driving in hilly areas, or select a lower gear range
(using the Electronic Range Select (ERS) shift
control) on more severe grades.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
When using the Cruise Control, if you experience
speed drops greater than 10 mph (16 km/h),
disengage until you can get back to cruising
speed.
Use Cruise Control in flat terrain and with light
loads to maximize fuel efficiency.
