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.
Engine Oil Change Indicator System
Oil Change Due
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Due” 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
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate, dependent
upon your personal driving style.Unless reset, this message will continue to display each
time you turn the ignition switch to the ON/RUN
position or cycle the ignition to the ON/RUN position if
equipped with Keyless Enter-N-Go. To turn off the
message temporarily, press and release the MENU but-
ton. To reset the oil change indicator system (after
performing the scheduled maintenance) refer to the fol-
lowing procedure.
Vehicles Equipped With Keyless Enter-N-Go
1. Without pressing the brake pedal, push the ENGINE
START/STOP button and cycle the ignition to the ON/
RUN position (Do not start the engine.)
2. Fully depress the accelerator pedal, slowly, three times
within 10 seconds.
3. Without pressing the brake pedal, push the ENGINE
START/STOP button once to return the ignition to the
OFF/LOCK position.

been deactivated. When this feature is deactivated, the
system reverts to the standard intermittent wiper
operation.
Hill Start Assist (HSA)
When this feature is selected, the HSA system is active.
Refer to “Electronic Brake Control System” in “Starting
And Operating” for system function and operating infor-
mation. To make your selection, press and release the
SELECT button until a check-mark appears next to the
feature showing the system has been activated or the
check-mark is removed showing the system has been
deactivated.
Blind Spot Alert
There are three selections when operating Blind Spot
Alert. By pressing and releasing the SELECT button once,
the Blind Spot Alert feature can be activated in “Blind
Spot: Lights Only” mode. When this mode is selected the
Blind Spot Monitor (BSM) system is activated and willonly show a visual alert in the outside mirrors. By
pressing and releasing the SELECT button a second time
“Blind Spot: Lights/CHM” mode is activated. In this
mode the Blind Spot Monitor (BSM) will show a visual
alert in the outside mirrors as well as an audible alert
when the turn signal is on. When “Blind Spot: Off” is
selected the Blind Spot Monitor (BSM) system is deacti-
vated.
NOTE:
If your vehicle has experienced any damage in
the area where the sensor is located, even if the fascia is
not damaged, the sensor may have become misaligned.
Take your vehicle to an authorized dealer to verify sensor
alignment. Having a sensor that is misaligned will result
in the BSM not operating to specification.
Forward Collision Warning
The Forward Collision Warning (FCW) feature can be can
be set to Far, set to Near or turned Off. The default status
of FCW is the Far setting. This means the system will

STARTING AND OPERATING 409

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
some accelerations, the clutch automatically disengages.
NOTE:
•The torque converter clutch will not engage, and the
transmission will not shift into the top overdrive gear,
until the transmission fluid and engine coolant are
warm [usually after 1 to 3 miles (1.6 to 4.8 km) of
driving]. Because top gear is disabled, and engine
speed is higher when the torque converter clutch is not
engaged, it may seem as if the transmission is not
shifting properly when cold. This is normal. Using theElectronic Range Select (ERS) feature, when the trans-
mission is sufficiently warm, will demonstrate that the
transmission is able to shift into and out of Overdrive.
•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
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 after starting the
engine.

Operating Instructions/
Precautions – If Equipped
The Quadra-Trac I is a single-speed (HI range only)
transfer case, which provides convenient full-time four-
wheel drive. No driver interaction is required. The Brake

440 STARTING AND OPERATING

4WD LOW To 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition switch in the ON position or the engine running,
shift the transmission into NEUTRAL, and press the
“4WD LOW” button once on the transfer case switch. The
“4WD LOW” indicator light in the instrument cluster
will flash and go out when the shift is complete.
NOTE:
•If shift conditions/interlocks are not met, or a transfer
case motor temperature protection condition exists, a
“For 4x4 High Slow Below 3 MPH or 5 KPH Put Trans
in N Press 4 Low” message will flash from the
Electronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further
information.
•Shifting into or out of 4WD LOW is possible with the
vehicle completely stopped; however, difficulty mayoccur due to the mating clutch teeth not being prop-
erly aligned. Several attempts may be required for
clutch teeth alignment and shift completion to occur.
The preferred method is with the vehicle rolling 0 to
3 mph (0 to 5 km/h). If the vehicle is moving faster
than 3 mph (5 km/h), the transfer case will not allow
the shift.
NEUTRAL Shift Procedure
1. Turn the ignition switch to the ON position, engine off.
2. Vehicle stopped, with foot on brake.
3. Place the transmission into NEUTRAL.
4. Hold down the NEUTRAL “pin” switch (with a pen,
etc.) for four seconds until the LED light by the switch
starts to blink indicating shift in progress. The light will
stop blinking (stay on solid) when the NEUTRAL shift is
complete.
444 STARTING AND OPERATING

If you stall or begin to lose forward motionwhile
climbing a steep hill, allow your vehicle to come to a stop
and immediately apply the brakes. Restart the engine,
and shift into REVERSE. Back slowly down the hill,
allowing the compression braking of the engine to help
regulate your speed. If the brakes are required to control
vehicle speed, apply them lightly and avoid locking or
skidding the tires.
WARNING!
If the engine stalls, you lose forward motion, or
cannot make it to the top of a steep hill or grade,
never attempt to turn around. To do so may result in
tipping and rolling the vehicle. Always back care-
fully straight down a hill in REVERSE gear. Never
back down a hill in NEUTRAL using only the brake. Remember, never drive diagonally across a hill always
drive straight up or down.
If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain forward motion
by turning the front wheels slowly. This may provide a
fresh “bite” into the surface and will usually provide
traction to complete the climb.
Traction Downhill
Shift the transmission into a low gear, and the transfer
case into 4WD LOW range. Let the vehicle go slowly
down the hill with all four wheels turning against engine
compression drag. This will permit you to control the
vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmis-
sion whenever possible.5
