NOTE: The warnings “LOCOOL” and “GASCAP” will
always be displayed in the odometer display.
U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.
14. Cruise Indicator Light This indicator lights when the speed control
system is turned ON. 15. Oil Pressure Warning Light
Shows low engine oil pressure. The light will come
on and remain on when the ignition switch is
turned from the OFF to the ON position, and the light
will turn off after the engine is started. If the bulb does
not come on, have the system checked by your autho-
rized dealer.
If the warning light comes on and remains on while
driving, stop the vehicle and shut off the engine. DO
NOT OPERATE THE VEHICLE UNTIL THE CAUSE IS
CORRECTED. Also, a single chime will sound.
16. Transmission Temperature Warning Light This light indicates that there is excessive trans-
mission fluid temperature that might occur with
severe usage such as trailer towing or snow plowing. If
this light comes on, stop the vehicle and run the engine at
idle or faster, with the transmission in N (Neutral) until
the light goes off.

WARNING!
When parking your vehicle, always leave a manual
transmission in first gear and apply the parking
brake fully to guard against vehicle movement and
possible injury or damage. Never use any gear as a
substitute for the parking brake.
CAUTION!
To drive as safely as possible and to prolong the life
of your manual transmission, follow these tips:
•Before shifting from a forward gear into reverse, or
from reverse to a forward gear, stop vehicle com-
pletely. Otherwise, accelerated transmission wear may
result.
•Do not operate at sustained high engine or road
speeds in lower gears. Engine damage may result.
•Do not downshift into a low gear while traveling at too
high a speed for that gear. Engine, clutch, or transmis-
sion damage may result.
•Do not rest your foot on the clutch pedal. This causes
heat buildup and damages the clutch.
•When you slow down or go up a grade, downshift as
speed requires or the engine may overheat.
•Never hold the vehicle stopped on a hill by using the
clutch pedal. The clutch may be damaged.
•During cold weather, you may experience increased
effort in shifting until the transmission fluid warms
up. This is normal.
•Push in the clutch pedal completely when shifting.
Otherwise, transmission or clutch damage may result.

CAUTION!
•Never press on the accelerator pedal with the
engine running, vehicle in gear, and the brakes
applied. Always apply the brakes when stopped
on a incline. Failure to follow these instructions
can cause overheating and damage to the trans-
mission.
•When “rocking” a stuck vehicle by moving be-
tween “First” and R (Reverse), do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
Over Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission gets too
hot, the transmission will change the way it shifts to help
control the condition. This may result in a slightly different feeling or response during normal operation in
D (Drive) position. If the transmission becomes hot
enough the TRANS TEMP warning light in the instru-
ment cluster will come on. After the transmission cools
down, it will return to normal operation.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops or during accelera-
tion, the clutch automatically and smoothly disengages.
NOTE:
•The torque converter clutch (TCC) will not engage
until the transmission fluid and engine coolant are
warm (usually after 1–3 miles (1.6–4.8 km) of driving)
and the vehicle speed is above approximately 30 mph
232 STARTING AND OPERATING
Page 233 of 424
(48 km/h). To understand the difference in operation,
drive the vehicle so that TCC engagement conditions
are correct, and then press and release the “O/D OFF”
button once to disengage the TCC. Wait a few seconds,
and then press and release the “O/D OFF” button
again to engage the TCC. You will notice that the
engine runs at a higher RPM when driving at vehicle
speeds above approximately 30 mph (48 km/h) with
the TCC not engaged. This is a normal condition.
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and will not cause damage to the
transmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear
position.
Rocking the Vehicle
If the vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the gear
selector rhythmically between “First” and R (Reverse),
while applying slight pressure to the accelerator.
The least amount of accelerator pedal pressure to main-
tain the rocking motion without spinning the wheels or
racing the engine is most effective. Racing the engine or
spinning the wheels, due to the frustration of not freeing
the vehicle, may lead to transmission overheating and
failure. Allow the engine to idle with the transmission
selector in N (Neutral) for at least one minute after every
five rocking-motion cycles. This will minimize overheat-
ing and reduce the risk of transmission failure during
prolonged efforts to free a stuck vehicle.

and/or the flow rate is reduced. If you must cross
flowing water avoid depths in excess of 9 inches. The
flowing water can erode the streambed causing your
vehicle to sink into deeper water. Determine exit point(s)
that are downstream of your entry point to allow for
drifting.
Standing Water
Avoid driving in standing water deeper than 20 inches,
and reduce speed appropriately to minimize wave ef-
fects. Maximum speed in 20 inches of water is less than 5
mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to assure the fluids have not been contami-
nated. Contaminated fluid (milky, foamy in appearance)
should be flushed/changed as soon as possible to pre-
vent component damage.Driving In Snow, Mud and Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4L or 4LO if necessary.
Refer to “Four-Wheel Drive Operation” in this section.
Do not shift to a lower gear than necessary to maintain
headway. Over-revving the engine can spin the wheels
and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads, be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE: Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to 4L or 4LO. Use
first gear and 4L or 4LO for very steep hills.
250 STARTING AND OPERATING

If using a manual transmission vehicle for trailer towing,
all starts must be in FIRST gear to avoid excessive clutch
slippage.
Towing Tips — Automatic Transmission
The “D” range can be selected when towing. However, if
frequent shifting occurs while in this range, the “3” range
should be selected.
NOTE: Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive 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. See Schedule “B” in
section 8 of this manual for transmission fluid change
intervals. NOTE:
Check the automatic transmission fluid level
before towing.
Towing Tips — O/D OFF (If Equipped)
To reduce potential for automatic transmission overheat-
ing, press the “O/D OFF” button when driving in hilly
areas or shift the transmission to Drive position 2 on
more severe grades. Refer to “Transmission Shifting” in
this section.
Towing Tips — Electronic Speed Control (If
Equipped)
Don’t 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.

TOWING A DISABLED VEHICLE
2WD Models Only
Provided the transmission is operable, tow only in N
(Neutral) at speeds not exceeding 30 mph (48 km/h), for
distances of not more than 15 miles (24 km). Towing at
more than 30 mph (48 km/h) or for more than 15 miles
(24 km) can cause severe transmission damage. If the
transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than 15
miles (24 km), tow with all four wheels OFFthe ground.
Acceptable methods are to tow the vehicle on a flatbed or
with one end of the vehicle raised and the other end on
a towing dolly. Removing the driveshaft for towing is not
recommended since this can allow fluid to drain from the
transmission.
4WD Models Only
The manufacturer recommends towing with all four
wheels OFFthe ground. Acceptable methods are to tow
the vehicle on a flatbed or with one end of the vehicle
raised and the other end on a towing dolly.

Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter. Do
not allow petroleum base fluid to contaminate the brake
fluid as seal damage will result.
Automatic Transmission
Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturer’s recommended transmis-
sion fluid, refer to Fluids, Lubricants, and Genuine Parts
for correct fluid type. It is important that the transmission
fluid be maintained at the prescribed level using the
recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturer’s recommended fluid will result in
more frequent fluid and filter changes. Refer to
Fluids, Lubricants, and Genuine Parts for correct
fluid type.
Fluid Level Check – 3.7L Gasoline Engine (42RLE)
and 2.8L Diesel Engine (545RFE)
This fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is
heated to its normal operating temperature. Operation of
the transmission with an improper fluid level will greatly
reduce the life of the transmission and of the fluid.
340 MAINTAINING YOUR VEHICLE
Page 341 of 424
To check the automatic transmission fluid level properly,
the following procedure must be used:
1. The vehicle must be on level ground.
2. The engine should be running at curb idle speed for a
minimum of 60 seconds.
3. Fully apply parking brake.
4. Apply the brakes and shift the transmission into P
(Park).
5. The fluid MUSTbe checked with the transmission in
P (Park) to be sure that the fluid level is accurate.
6. Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.
At normal operating temperature (approximately 180° F
(82° C), the fluid level is correct if it is in the HOT region (cross-hatched area) on the oil level indicator. The fluid
level indicator should be in the COLD region at 70° F (21°
C) fluid temperature.
If the fluid level is low, add sufficient fluid to bring to the
proper level. Refer to Fluids, Lubricants and Genuine
Parts for correct fluid type.
Fluid is added through the dipstick tube.
NOTE:
To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
certain that the dipstick cap is properly reseated.
Special Additives
The manufacturer recommends against the addition of
any additives to the transmission. Exception to this
policy is the use of special dyes to aid in detecting fluid
leaks.
