66STARTING AND OPERATING
Overdrive Operation

The automatic transmission includes an
electronically controlled Overdrive (SIXTH gear).
The transmission will automatically shift into
Overdrive if the following conditions are present:

The gear selector is in the DRIVE position.
The transmission fluid has reached an
adequate temperature.
The engine coolant has reached an adequate
temperature.
The vehicle speed is sufficiently high.
The driver is not heavily pressing the acceler -
ator.
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.
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 and engine
coolant are 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 into Overdrive
when cold. This is normal. Using the Elec
-
tronic Range Select (ERS) shift control, when
the transmission is sufficiently warm, will
demonstrate that the transmission is able to
shift into and out of Overdrive.
If the vehicle has not been driven for several
days, the first few seconds of operation after
shifting the transmission into gear may seem
sluggish. This is due to the fluid partially
draining from the torque converter into the
transmission. This condition is normal and
will not cause damage to the transmission.
The torque converter will refill within five
seconds after starting the engine.
POWER STEERING

The standard power steering system will
provide increased vehicle response and ease
of maneuverability. 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.

21_VF_OM_EN_USC_t.book Page 66

STARTING AND OPERATING69
TO ACCELERATE FOR PASSING
While the Cruise Control system is set, press the
accelerator to pass as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
Using Cruise Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise Control system maintains speed up
and down hills. A slight speed change on
moderate hills is normal. On steep hills, a
greater speed loss or gain may occur so it may
be preferable to drive without Cruise Control.
TO RESUME SPEED
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h) up to the
maximum speed of 100 mph (160 km/h).
TO DEACTIVATE
A soft tap on the brake pedal, pushing the RES
button, or normal brake pressure while slowing
the vehicle will deactivate Cruise Control
without erasing the set speed memory. Rotating
the center ring upward to turn the system off or
placing the ignition in the STOP (OFF/LOCK)
position erases the set speed memory.
PARKSENSE REAR PARK ASSIST — IF
EQUIPPED
The ParkSense Rear Park Assist system
provides an audible indication of the distance
between the rear fascia/bumper and a
detected obstacle when backing up (e.g. during
a parking maneuver) Úpage 72.
The ParkSense Rear Park Assist is
automatically activated when the transmission
is placed into REVERSE. As the distance from an
obstacle behind the vehicle decreases, the
audible alert becomes more frequent.
Interaction With Trailer Towing
The Rear Park Assist system is automatically
deactivated when a trailer is hitched to the
vehicle. The system will be automatically
activated as soon as the trailer is removed.
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the
conditions, and you could lose control and
have an accident. Do not use Cruise Control
in heavy traffic or on roads that are winding,
icy, snow-covered or slippery.

70STARTING AND OPERATING
PARKSENSE REAR PARK ASSIST
S
ENSORS
The four ParkSense Rear Park Assist sensors,
located in the rear fascia/bumper, monitor the
area behind the vehicle that is within the
sensors’ field of view. The sensors can detect
obstacles, in the horizontal direction, from
approximately 12 inches (30 cm) up to
55 inches (140 cm) from the center of the rear
fascia/bumper and up to 24 inches (60 cm)
from the corners of the rear fascia/bumper,
depending on the location, type and orientation
of the obstacle.
Rear Park Assist Sensors Location

If several obstacles are detected, the
ParkSense Rear Park Assist system indicates
the nearest obstacle.
The minimum height of a detectable obstacle
corresponds to the maximum height of an
obstacle that would clear the underside of the
vehicle during the parking maneuver.
PARKSENSE REAR PARK ASSIST
A
LERTS
If an obstacle is behind the vehicle when
REVERSE gear is engaged, an audible alert is
activated.
The tones emitted by the loudspeaker inform
the driver that the vehicle is approaching an
obstacle. The pauses between the tones are
directly proportional to the distance from the
obstacle. Pulses emitted in quick succession
indicate the presence of a very close obstacle.
A continuous tone indicates that the obstacle is
less than 12 inches (30 cm) away.

21_VF_OM_EN_USC_t.book Page 70

STARTING AND OPERATING71
While audible signals are emitted, the audio system is not muted.
The audible signal is turned off immediately if the distance increases. The tone cycle remains constant if the distance measured by the inner sensors
is constant. If this condition occurs for the external sensors, the signal is turned off after three seconds (stopping warnings during maneuvers parallel
to walls).

AILURE INDICATIONS
A malfunction of the ParkSense Rear Park
Assist sensors or system is indicated, during
REVERSE gear engagement, by the instrument
panel warning icon.
The warning icon is illuminated and a
message is displayed in the
instrument cluster display (if
equipped) Ú page 48.
The sensors and wiring are tested continuously
when the ignition is in the MAR (ACC/ON/RUN)
position. Failures are indicated immediately if
they occur when the system is on.
Even if the system is able to identify that a
specific sensor is in failure condition, the
instrument cluster display shall indicate that
the ParkSense Rear Park Assist system is
unavailable, without reference to the sensor in
failure condition. If even a single sensor fails,
the entire system must be disabled. The system
is turned off automatically.
CLEANING THE PARKSENSE SYSTEM
Clean the Rear Park Assist sensors with water,
car wash soap and a soft cloth. Do not use
rough or hard cloths. In washing stations, clean
sensors quickly keeping the vapor jet/high
pressure washing nozzles at least 4 inches
(10 cm) from the sensors. Do not scratch or
poke the sensors.

YSTEM USAGE PRECAUTIONS
NOTE:
Ensure that the outer surface and the under -
side of the rear fascia/bumper is clean and
clear of snow, ice, mud, dirt or other obstruc -
tion to keep the Rear Park Assist system
operating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of Rear
Park Assist.
Clean the Rear Park Assist sensors regularly,
taking care not to scratch or damage them.
The sensors must not be covered with ice,
snow, slush, mud, dirt or debris. Failure to do
so can result in the system not working prop -erly. The Rear Park Assist system might not
detect an obstacle behind the fascia/
bumper, or it could provide a false indication
that an obstacle is behind the fascia/
bumper.
Objects such as bicycle carriers, etc., must
not be placed within 12 inches (30 cm) from
the rear fascia/bumper while driving the
vehicle. Failure to do so can result in the
system misinterpreting a close object as a
sensor problem, causing a failure indication
to be displayed in the instrument cluster
display.
WARNING!
Drivers must be careful when backing up
even when using ParkSense. Always check
carefully behind your vehicle, look behind
you, and be sure to check for pedestrians,
animals, other vehicles, obstructions, and
blind spots before backing up. You are
responsible for safety and must continue to
pay attention to your surroundings. Failure
to do so can result in serious injury or
death.
