27. Transmission Temperature Warning 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 Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
Continued operation with the Transmission Tem-
perature Warning Light illuminated could cause the
fluid to boil over, come in contact with hot engine or
exhaust components causing a fire that may result in
personal injury.
For vehicles equipped with a premium cluster this warn-
ing light will display in the Electronic Vehicle Informa-
tion Center (EVIC). Refer to ”Electronic Vehicle Informa-
tion Center (EVIC) — If Equipped” for further
information.

•Electronic Throttle Control (ETC) LightThis light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned ON 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.
If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when the
vehicle has completely stopped and the shift lever is
placed in the PARK position. The light should turn off.
If the light remains lit with the engine running your
vehicle, will usually be drivable, however, see an autho-
rized dealer for service as soon as possible. If the light is
flashing when the engine 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.•Engine Temperature Warning Light This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
pass H,the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for more information.

•SERV 4WDThe SERV 4WD light monitors the electric shift
4WD system. If the SERV 4WD light stays on or
comes on during driving, it means that the
4WD system is not functioning properly and
that service is required.
•Transmission Temperature Light This 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.
•Loose Gascap Message If the vehicle diagnostic system determines
that the fuel filler cap is loose, improperly
installed, or damaged, a loose gascap icon 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).
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The Oil Change Required message will
flash in the EVIC display for approximately 10 seconds
after a single chime has sounded to indicate the next
scheduled oil change interval. The engine oil change

column shift lever down (-) or up (+) to select the desired
top gear. For example, if the driver shifts the transmission
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 5.7L engines, use of ERS (or
“TOW/HAUL” mode) also enables an additional under-
drive gear which is not normally used during through-
gear accelerations. This additional gear improves vehicle
performance and cooling capability when towing a trailer
on certain grades. In ERS mode, first through third gear
are underdrive gears, and fourth gear is direct drive. ERS
fifth gear (Overdrive) is the same as the normal fourth
gear.
When in the DRIVE position in first through fourth gear,
the first tap down (-), will display the ERS designation for
the current gear (the transmission will not downshift).
For example, if you are in DRIVE and are in third (direct)
gear, when you tap the shift lever/switch one time in the
(-) direction, the display will show 4 (ERS 4 is direct gear).
Another tap down (-) will shift the transmission down to
ERS 3 (the added underdrive gear). When in the DRIVE
position in fifth gear, the first tap down (-) will downshift

STARTING AND OPERATING 271

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
operating in the “TOW/HAUL” mode, fifth gear is
disabled and 2-3 and 3-4 shift patterns are modified.Shifts into Overdrive (normal fourth gear) are allowed
during steady cruise (for improved fuel economy) and
automatic closed-throttle downshifts to direct gear and a
special underdrive gear (refer to “Electronic Range Se-
lect” in this section) are performed (for improved brak-
ing) when driving conditions warrant.

For additional information on the appropriate use of each
transfer case mode position, see the information below:
2H
Rear-Wheel Drive High Range - This range is for normal
street and highway driving on dry hard surfaced roads.
4H
Four-Wheel Drive High Range - This range locks the
front and rear driveshafts together forcing the front and
rear wheels to rotate at the same speed. Additional
traction for loose, slippery road surfaces only.
N
Neutral - This range disengages the front and rear
driveshafts from the powertrain. To be used for flat
towing behind another vehicle. Refer to “Recreational
Towing” in “Starting and Operating” for further
information.
4L
Four-Wheel Drive Low Range - This range locks the front
and rear driveshafts together forcing the front and rear
wheels to rotate at the same speed. Additional traction
and maximum pulling power for loose, slippery road
surfaces only. Do not exceed 25 mph (40 km/h).
Shifting Procedure – Manually Shifted Transfer
Case
2H⇔4H
Shifting between 2H and 4H can be made with the
vehicle stopped or in motion. If the vehicle is in motion,
shifts can be made up to 55 mph (88 km/h). With the
vehicle in motion, the transfer case will engage/
disengage faster if you momentarily release the accelera-
tor pedal after completing the shift. Apply a constant
force when shifting the transfer case lever.
