•Transmission Temperature LightThis light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Indicator illuminated will eventually cause se-
vere transmission damage or transmission failure.
WARNING!
If the Transmission Temperature Warning Light is
illuminated and you continue operating the vehicle,
in some circumstances you could cause the fluid to
boil over, come in contact with hot engine or exhaust
components and cause a fire.
•Loose Gascap Indicator If the vehicle diagnostic system determines
that the fuel filler cap is loose, improperly
installed, or damaged, a loose gascap indicator
will display in the telltale display area. Tighten
the fuel filler cap properly and press the SELECT button
to turn off the message. If the problem continues, the
message will appear the next time the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).

transmission will automatically shift from third gear to
OVERDRIVE if the following conditions are present:
•the shift lever is in DRIVE
•the engine coolant has reached normal operating tem-
perature
•vehicle speed is above approximately 30 mph
(48 km/h)
•the TOW/HAUL switch has not been activated
•the transmission has reached normal operating
temperature
NOTE: If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into OVER-
DRIVE and will automatically select the most desirable
gear for operation at this temperature. Normal operation
will resume when the transmission fluid temperature has
risen to a suitable level. If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough, the “Transmission
Temperature Warning Light” may illuminate and the
transmission may downshift out of OVERDRIVE until
the transmission cools down. After the transmission cools
down, the transmission will resume normal operation.
The transmission will downshift from OVERDRIVE to
DRIVE if the accelerator pedal is fully pressed at vehicle
speeds above approximately 35 mph (56 km/h).
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL switch. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When

into 3 (third gear), the transmission will never shift above
third gear, but can shift down to 2 (second gear) or 1 (first
gear), when needed.On vehicles equipped with 4.7L or 5.7L engines, 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 im-
proves vehicle performance and cooling capability when
towing a trailer on certain grades. In ERS mode, first

Overdrive Operation
The Overdrive automatic transmission contains an elec-
tronically controlled fourth and fifth gear (Overdrive).
The transmission will automatically shift from DRIVE to
Overdrive if the following conditions are present:
•the shift lever is in DRIVE;
•the engine coolant (antifreeze) has reached normal
operating temperature;
•vehicle speed is above approximately 30 mph
(48 km/h);
•the TOW/HAUL switch has not been activated;
•transmission has reached normal operating
temperature.
NOTE: If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive
and will automatically select the most desirable gear for operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough, the “Transmission
Temperature Warning Light” may illuminate and the
transmission may downshift out of Overdrive until the
transmission cools down. After cool down, the transmis-
sion will resume normal operation.
The transmission will downshift from Overdrive to
DRIVE if the accelerator pedal is fully pressed at vehicle
speeds above approximately 35 mph (56 km/h).

NOTE:Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid reaches
operating temperature.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes Anti-Lock Brake Sys-
tem (ABS), Traction Control System (TCS), Brake Assist
System (BAS), Hill Start Assist (HSA), Electronic Stability
Control (ESC) and Trailer Sway Control (TSC). All of the
systems work together to enhance vehicle stability and
control in various driving conditions, and are commonly
referred to as ESC.
Anti-Lock Brake System (ABS)
The ABS aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lockup and
help avoid skidding on slippery surfaces during braking. NOTE:
ABS improves steering control of the vehicle
during hard braking maneuvers.
WARNING!
•ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that af-
forded by the condition of the vehicle brakes and
tires or the traction afforded.
•The ABS cannot prevent collisions, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing.
•The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety
or the safety of others.
