The electronic control system consists of the powertrain control module (PCM), sensors, and solenoid valves.
Shifting and lock-up are electronically controlled for comfortable driving under all conditions.
The PCM receives input signals from sensors, switches, and other control units, processes data, and outputs signals
for the engine control system and the A/T control system. The A/T control system includes shift control, grade logic
control, clutch pressure control, and lock-up control.
The PCM switches the shift solenoid valves and the A/T clutch pressure control solenoid valves ON and OFF to control
gear selection and torque converter clutch lock-up.

Î Shift Control - Manual Shift Mode
D-Paddle Shift Mode
14-43
SHIFT INDICATOR
The transmission is provided with a D-paddle shift mode in D, and with a sequential sportshift mode in S. Both modes
are entered by pressing the paddle shifter (upshift switch) or the paddle shifter (downshift switch) while driving.
When the transmission is switched into the D-paddle shift mode by pressing the paddle shifters while driving in D, the
transmission can shift into a lower gear by pressing the paddle shifter (downshift switch), and it can shift into a
higher gear by pressing the paddle shifter (upshift switch). When the transmission shifts into a lower gear or a
higher gear by pressing the paddle shifters, the shift indicator in the gauge control module (tach) displays the number
of current gear selected. This number of the gear goes off when the transmission downshifts automatically, or when
the transmission upshifts automatically while coasting.
The transmission stays in 5th gear if the paddle shifter (upshift switch) is pressed when driving in 5th gear, and the
shift indicator displays ‘‘5’’ for 2 seconds, then goes off. The transmission stays in 1st gear if the paddle shifter is
pressed when driving in 1st gear, and the shift indicator displays ‘‘1’’ for 2 seconds, then goes off.
The transmission stays in the current gear and does not upshift to the next higher gear if the paddle shifter is
pressed while driving below the minimum allowable speed, and the shift indicator blinks the number of the next
higher gear several times, then returns to the number of the current gear.
NOTE: D-paddle shift mode has been added for ’08-09 models.

System Description (cont’d)
SHIFT INDICATOR
’’M’’ INDICATOR
The S position has two shifting modes; the automatic shift mode and the sequential sportshift mode. In the S position
automatic shift mode, the transmission upshifts and downshifts automatically from 1st through 4th gear, and the
paddle shifters are ready to be activated to switch to the sequential sportshift mode. In the automatic shift mode, the
shift indicator and the M indicator in the gauge control module (tach) do not come on.
When the paddle shifter (upshift switch) or the paddle shifter (downshift switch) is pressed, the automatic shift
mode is canceled and the sequential sportshift mode comes into operation. The shift indicator displays the number of
the selected gear, and the M indicator comes on. In the sequential sportshift mode, the driver can shift up and down
manually from 1st through 5th gear by using the paddle shifters, much like a manual transmission. The paddle shifters
are installed on the back of the steering wheel, and the driver can shift gears by pressing the paddle shifters without
taking either hand off the steering wheel.
In the sequential sportshift mode, the transmission must be shifted up and down by pressing the paddle shifters.
However, the transmission cannot downshift and stays in the current gear if the paddle shifter is pressed while the
vehicle is coasting at a speed that would cause the engine to over-rev by downshifting the transmission, and the shift
indicator blinks the number of the selected gear several times, then returns to the number of the current gear. If the
vehicle speed reaches an appropriate speed while the shift indicator is blinking the number of the selected gear, the
transmission downshifts and the shift indicator displays the selected gear. The transmission also cannot upshift and
stays in the current gear if the paddle shifter is pressed while driving below an appropriate upshifting speed, the
shift indicator blinks the number of the selected gear several times, then returns to the number of the current gear. If
the vehicle speed reaches an appropriate upshift speed while the shift indicator is blinking the number of the selected
gear, the transmission upshifts and the shift indicator displays the selected gear.
This mode has automatic downshifting areas so the vehicle can run smoothly with more power to cope with upcoming
acceleration. When coasting in 5th gear or 4th gear, the transmission downshifts to the next lower gear if the vehicle
slows down to the programmed speed, or by pressing the brake pedal.
When the transmission decelerates to a stop, the transmission shifts to 1st gear automatically. The transmission can
be shifted to 2nd gear by pressing the paddle shifter while the vehicle is stopped, and the vehicle can start off in 2nd
gear.
The sequential sportshift mode is canceled when moving the shift lever to any position other than S.

15. Drive the vehicle in 4th or 5th gear with the shift lever in S with the sequential sportshift mode, then
decelerate and downshift to 2nd gear by pressing
the paddle shifter (downshift switch). The
vehicle should immediately begin to slow down
from the engine braking, then slow to a stop.
16. Shift to R, accelerate from a stop at full throttle momentarily, and check for abnormal noise and
clutch slippage. 17. Park the vehicle on a slope (about 16-degrees),
apply the brake, and shift into P. Release the brake;
the vehicle should not move.
NOTE: Always use the brake to hold the vehicle,
when stopped on an incline in gear. Depending on
the grade of the incline, the vehicle could roll
backwards if the brake is released.

Overview

System Description
The navigation system is a highly sophisticated, hybrid locating system.
The navigation unit uses global positioning system (GPS) satellite signals, internal yaw and vehicle speed inputs, and
a map database to show where the vehicle is and to help guide you to a desired destination.
The navigation unit’s GPS receiver receives signals from the GPS, a network of 24 satellites in orbit ar ound the earth.
By receiving signals from several of these satellites, the navigation system can determine the latitude, l ongitude, and
elevation of the vehicle.
Signals from the system’s yaw rate sensor (inside the navigation unit) detects turns, and the ECM/PCM vehicle speed
pulse (VSP) and reverse signal enable the system to keep track of the vehicle’s speed and direction of travel. The
advantage of this hybrid system is that the system can track your position if either the GPS signal or the vehicle speed
signal is missing. For instance, when in a tunnel (no GPS), the speed signal is used to update your position on the map.
Alternately, while the vehicle is being transported on a ferry, GPS signals can show the vehicle position on the map as
it crosses the water.
The navigation system uses the location, direction, and speed information to display the appropriate map and
calculate a route to the destination entered. As you drive to a destination, the system provides both visual and audio
guidance. Audio guidance is sent to the audio unit, and an RGB graphics color signal is sent to the navigation display.
This navigation system also has voice recognition that allows voice control of most of the navigation, and audio
functions. The voice control switches (navigation TALK and navigation BACK buttons on the steering wheel) activate
the voice control system. The microphone on the ce iling receives your voice commands. For more information on this
feature, consult the navigation owner’s guide.
The illumination signal is used by the navigation unit to automatically switch the display mode between the Night and
Day display modes. When the headlights are on, the dash brightness control setting full brightness overrides the Night
display mode, and allows a daytime navigation display with the lights on.
When the navigation system is giving voice guidance commands, the front speakers are muted. When the voice
control system is being used (navigation TALK button pressed), all of the speakers are muted.
The internal GA-Net II bus passes information back and forth between the navigation display, the navigation unit, and
the audio system components. The information passed on this bus are touch button commands, audio muting signal,
audio (radio and XM), and any open in these bus lines can affect the navigation system or other audio accessory
operation.
The clock on the navigation display is set and maintained by the navigation unit. The time is automatically adjusted for
daylight savings, and time zone changes while driving. The time can be adjusted in setup.
Additional information is available about the navigation components following the System Diagram. A glossary of
terms that are used throughout this section follows the detailed information.
The Navigation System Manual in the glove box covers all of the system functions and settings. Use this as a resource
when evaluating a client concern.
