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.

•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

DRIVE
This range provides all forward gears, including third
gear direct and fourth and fifth gear overdrive (Refer to
Overdrive Operation). Use this range for most city and
highway driving.
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.
274 STARTING AND OPERATING

The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the “TOW/HAUL” mode is desired,
the button must be pressed 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 automati-
cally 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
acceleration when the transmission downshifts to second
gear, the clutch automatically disengages.
NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant (antifreeze) arewarm [usually after 1 to 3 miles (1.6 to 4.8 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. Pressing the “TOW/HAUL”
switch 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 in several days, the
first few seconds of operation after shifting the trans-
mission 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 con-
verter will refill within five seconds of shifting from
PARK into any other gear position.
276 STARTING AND OPERATING

CAUTION! (Continued)
•Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., engine oil,
transmission/transaxle, axle, etc.) for signs of con-
tamination (i.e., fluid that is milky or foamy in
appearance) after driving through standing water.
Do not continue to operate the vehicle if any fluid
appears contaminated, as this may result in further
damage. Such damage is not covered by the New
Vehicle Limited Warranty.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
290 STARTING AND OPERATING

Power Steering Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an autho-
rized dealer.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power
steering components. Such damage is not covered by
the New Vehicle Limited Warranty.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do
not overfill. Use only manufacturer’s recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied, the engine is off and the key fob is
removed from the ignition switch. Also, be certain to
leave an automatic transmission in PARK, or manual
transmission in REVERSE or first gear.
292 STARTING AND OPERATING

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer up in an area away from heavy
traffic.
Automatic Transmission
The “DRIVE” range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, select
“TOW/HAUL” mode (if equipped) or select a lower gear
using the Electronic Range Select (ERS) feature.
NOTE:Using “TOW/HAUL” mode or a lower gear
range while operating the vehicle under heavy operating
conditions will improve performance and extend trans-
mission life by reducing excessive shifting and heat build
up. This action will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you regularly tow a trailer for more than
45 minutes of continuous operation. Refer to “Mainte-
nance Schedule” for the proper maintenance intervals. NOTE:
Check the automatic transmission fluid level
before towing.
Tow/Haul
To reduce potential for automatic transmission overheat-
ing, turn the “TOW/HAUL” feature ON when driving in
hilly areas, or select a lower gear range (using the
Electronic Range Select (ERS) feature) on more severe
grades.
Electronic Speed Control – If Equipped

Do not use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.

4. Press the brake pedal.
5. Shift the transmission into NEUTRAL.
6. Shift the transfer case lever into desired position.
7. Shift the transmission into PARK.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!
•Do not use a bumper-mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
•Do not disconnect the rear driveshaft because
fluid will leak from the transfer case and damage
the internal parts.
