System Information
Shared Modes
This allows the VES™ to output radio sources to the
headphones and the radio to output VES™ sources to the
vehicle speakers. When the radio and VES™ channel 1 or
2 are in the same (shared) mode, a VES™ icon will be
visible on the radio’s display for that channel, and the
shared icon will be visible on the VES™ screen. When in
shared mode, the same audio source is heard in the
shared headphone channel 1 or channel 2.
If the radio functions (FM, AM, or SAT) are in the shared
mode with the VES™, only the radio is able to control the
radio functions. In this case, VES™ can share the radio
mode, but not change stations until the radio mode is
changed to a mode that is different from the VES™ selected radio mode. When shared, the radio has priority
over the VES™ or all radio modes (FM, AM). The VES™
has the ability to switch tuner (AM/FM), SEEK, SCAN,
TUNE, and recall presets in radio modes as long as it is
not in shared mode.
When in shared disc both the radio and the VES™ have
control of the video functions. The VES™ has the ability
to control the following video modes:
1. CD: Ability to Fast Forward, Rewind, Scan, and Track
Up/Down.
2. CD Changer (in radio): Ability to Disk Up/Down and
program all listed CD controls (Fast Forward, Rewind,
Scan, and Track Up/Down).
The VES™ can even control radio modes or video modes
while the radio is turned off. The VES™ can access the
radio modes or disc modes by navigating to those modes
on the VES™ and activating a radio mode or disc mode.

The button located in the center of the left-hand control
will tune to the next preset station that you have pro-
grammed in the radio preset pushbutton.
CD Player
Pressing the top of the switch once will go to the next
track on the CD. Pressing the bottom of the switch once
will go to the beginning of the current track, or to the
beginning of the previous track if it is within one second
after the current track begins to play.
If you press the switch up or down twice, it plays the
second track; three times, it will play the third, etc.
The center button on the left side rocker switch has no
function for a single-disc CD player. However, when a
multiple-disc CD player is equipped on the vehicle, the
center button will select the next available CD in the
player.
CD/DVD DISC MAINTENANCE
To keep a CD/DVD in good condition, take the following
precautions:
1. Handle the disc by its edge; avoid touching the
surface.
2. If the disc is stained, clean the surface with a soft cloth,
wiping from center to edge.
3. Do not apply paper or tape to the disc; avoid scratch-
ing the disc.
4. Do not use solvents such as benzene, thinner, cleaners,
or anti-static sprays.

DRIVE
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,
and third gears, direct fourth gear and overdrive fifth
gear. The DRIVE position provides optimum driving
characteristics under all normal operating conditions.
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 Electronic Range
Select (ERS) feature (refer to “Electronic Range Select
(ERS)” in this section) to select a lower gear range. Under
these conditions, using a lower gear range will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup.
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 the current gear until the vehicle is brought to a stop.
After the vehicle has stopped, the transmission will
remain in second gear regardless of which forward gear
is selected. PARK, REVERSE, and NEUTRAL will con-
tinue 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
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 switch to the LOCK/OFF position.
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 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.Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the shift
lever is in the DRIVE position. For example, if you shift
the transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gear normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Tapping the shift
lever to the left (-) will downshift the transmission,
activate ERS mode, display the current gear in the
instrument cluster, and maintain that gear as the top
available gear. Once in ERS mode, tapping the shift lever
to the left (-) or right (+) will change the top available
gear.
428 STARTING AND OPERATING

Downshifting the transmission to the lowest possible
gear (when climbing a grade), or shifting to NEUTRAL
(when stopped in heavy traffic) can help to reduce this
excess heat generation.
During cold temperatures, transmission operation may
be modified depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency. Engagement of both the
torque converter clutch and the top overdrive gear are
inhibited until the transmission fluid is warm (refer to the
“Note” under “Torque Converter Clutch” in this section).
During extremely cold temperatures (-16°F [-27°C] or
below), operation may briefly be limited to first and
direct gears only. 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 remains
in third gear regardless of which forward gear is selected.
PARK, REVERSE, and NEUTRAL will continue to oper-
ate. The Malfunction Indicator Light (MIL) may be illu-
minated. Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service without dam-
aging 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 switch to the LOCK/OFF position.

Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the shift
lever is in the DRIVE position. For example, if you shift the transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gear normally.
Use of ERS (or TOW/HAUL mode) also enables an
additional underdrive gear which is not normally used
during through-gear accelerations. This additional gear
can improve vehicle performance and cooling capability
when towing a trailer on certain grades. In ERS mode,
gears 1 though 3 are underdrive gears, and ERS 4 is direct
drive. ERS 5 and 6 (Overdrive gears ) are the same as the
normal fourth and fifth gears.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Tapping the shift
lever to the left (-) will activate ERS mode, display the
current gear in the instrument cluster, and maintain that

CAUTION!
•Using a transmission fluid other than the manu-
facturer’s recommended fluid may cause deterio-
ration in transmission shift quality and/or torque
converter shudder. Using a transmission fluid
other than that recommended by the manufacturer
will require more frequent fluid and filter
changes. Refer to “Fluids, Lubricants, and Genu-
ine Parts” in “Maintaining Your Vehicle” for fur-
ther information.
•The fluid level is preset at the factory and it does
not require adjustment under normal operating
conditions. If a transmission fluid leak occurs,
visit your authorized dealer immediately. Severe
damage to the transmission may occur. Your au-
thorized dealer has the proper tools to adjust the
fluid level accurately.
Fluid Level Check – 5.7L Engine
Check the fluid level while the transmission is at normal
operating temperature. This occurs after at least 15 miles
(25 km) of driving. At normal operating temperature the
fluid cannot be held comfortably between the fingertips.
To check the fluid level properly, the following procedure
must be used:
1. Operate the engine at idle speed and normal operating
temperature.
2. The vehicle must be on level ground.
3. Fully apply the parking brake, and press the brake
pedal.
4. Place the shift lever momentarily in each gear position
ending with the shift lever in PARK.
5. Remove the dipstick, wipe it clean and reinsert it until
seated.
