Oil Temperature Warning Light
Red Telltale Light What It Means
Oil Temperature Warning Light
This telltale indicates engine oil temperature is high. If the light turns on while driving, stop the vehicle and shut off the en-
gine as soon as possible.
Battery Charge Warning Light
Red Telltale Light What It Means
Battery Charge Warning Light
This light illuminates when the battery is not charging properly. If it stays on while the engine is running, there may be a
malfunction with the charging system. Contact your authorized dealer as soon as possible. This indicates a possible prob-
lem with the electrical system or a related component.
If jump starting is required, refer to “Jump Starting Procedures” in “What To Do In Emergencies.”

Low Washer Fluid Indicator Light — If Equipped
Yellow Telltale Light What It Means
Low Washer Fluid Indicator Light — If Equipped
This indicator will illuminate when the windshield washer fluid is low.
Transmission Temperature Indicator Light
Yellow Telltale Light What It Means
Transmission Temperature Indicator Light
This light indicates that the transmission fluid temperature is running hot. This may occur with severe usage, such as
trailer towing. If this light turns on, safely pull over and stop the vehicle. Then, shift the transmission into NEUTRAL and
run the engine at idle or faster until the light turns off.
CAUTION!
Continuous driving with the Transmission Tem-
perature Warning Light illuminated will eventu-
ally cause severe transmission damage or
transmission failure.
WARNING!
If you continue operating the vehicle when
the Transmission Temperature Warning Light
is illuminated you could cause the fluid to boil

Engine Oil Change Indicator System
— If Equipped
Oil Change Required
Your vehicle is equipped with an engine oil
change indicator system. The “Oil Change Re-
quired” message will display in the EVIC display
for approximately five seconds after a single
chime has sounded to indicate the next sched-
uled oil change interval. The engine oil change
indicator system is duty-cycle based, whichmeans the engine oil change interval may fluc-
tuate dependent upon your personal driving
style.
Unless reset, this message will continue to
display each time you place the ignition in the
ON/RUN position. To turn off the message
temporarily, push and release the Trip Odom-
eter button on the instrument cluster. To reset
the oil change indicator system (after perform-
ing the scheduled maintenance), refer to the
following procedure.
1. Place the ignition in the ON position.Do not
start the engine.
2. Fully push the accelerator pedal, slowly,
three times within 10 seconds.
3. Place the ignition in the OFF/LOCK position.
NOTE:
If the indicator message illuminates when
you start the vehicle, the oil change indica-
tor system did not reset. If necessary, repeat
this procedure.

CAUTION!(Continued)
NEUTRAL can cause severe transmission
damage. Refer to “Recreational Towing” in
“Starting And Operating” and “Towing A Dis-
abled Vehicle” in “What To Do In Emergen-
cies” for further information.
DRIVE (D)
This range should be used for most city and
highway driving. It provides the best fuel
economy. The DRIVE position provides opti-
mum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, travel-
ing into strong head winds, or while towing
heavy trailers), use the AutoStick shift control (if
equipped, refer to"AutoStick (CVT)"in this
section for further information) to select a lower
gear ratio. Under these conditions, using a
lower gear ratio will improve performance and
extend transmission life by reducing excessive
shifting and heat buildup.During sustained high speed driv-
ing or trailer towing up long grades
on hot days, the automatic trans-
mission oil may become too hot. If
this happens, the transmission
overheat indicator light will come on, and the
vehicle will slow slightly until the transmission
cools down enough to allow a return to the
requested speed. This is done to prevent trans-
mission damage due to overheating. If the high
speed is maintained, the overheating may reoc-
cur, as before, in a cyclic fashion.
LOW (L) — If Equipped
Use this range for engine braking when de-
scending very steep grades. In this range, the
transmission will downshift for maximum engine
braking, and upshifts will occur only to prevent
engine overspeed.
AUTOSTICK
AutoStick (Six-Speed Automatic
Transmission) — If Equipped
AutoStick is a driver-interactive transmission
feature providing manual shift control, givingyou more control of the vehicle. AutoStick al-
lows you to maximize engine braking, eliminate
undesirable upshifts and downshifts, and im-
prove overall vehicle performance. This system
can also provide you with more control during
passing, city driving, cold slippery conditions,
mountain driving, trailer towing, and many other
situations.
Operation
When the gear selector is in the DRIVE position,
the transmission will operate automatically,
shifting between the six available gears. To
engage AutoStick, simply tap the gear selector
to the right or left (+/-) while in the DRIVE
position. Tapping (-) to enter AutoStick mode will
downshift the transmission to the next lower
gear, while using (+) to enter AutoStick mode
will retain the current gear. When AutoStick is
active, the current transmission gear is dis-
played in the instrument cluster.
In AutoStick mode, the transmission will shift up
or down when the driver moves the gear selec-
tor to the right (+) or left (-), unless an engine
lugging or overspeed condition would result. It

WARNING!
Do not descend a steep grade in NEUTRAL.
Use vehicle brakes in conjunction with en-
gine braking. Descending a grade too fast
could cause you to lose control and be
seriously injured or killed.
Driving Across An Incline
If at all possible avoid driving across an incline.
If it is necessary, know your vehicle’s abilities.
Driving across an incline places more weight on
the down-hill wheels, which increases the pos-
sibilities of a down-hill slide or rollover. Make
sure the surface has good traction with firm and
stable soils. If possible transverse the incline at
an angle heading slightly up or down.
WARNING!
Driving across an incline increases the risk of
a rollover, which may result in severe injury.
If You Stall Or Begin To Lose Headway
If you stall or begin to lose headway while
climbing a steep hill, allow your vehicle to cometo a stop and immediately apply the brake.
Restart the engine and shift to REVERSE. Back
slowly down the hill allowing engine and hill
descent braking to control the descent and
apply your brakes if necessary, but do not allow
the tires to lock.
WARNING!
If the engine stalls or you lose headway 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,
which may result in severe injury. Always
back carefully straight down a hill in RE-
VERSE gear. Never back down a hill in
NEUTRAL using only the vehicle brakes.
Never drive diagonally across a hill, always
drive straight up or down.
Driving Through WaterExtreme care should be taken crossing any
type of water. Water crossings should be
avoided if possible, and only be attempted
when necessary in a safe responsible manner.You should only drive through areas which are
designated and approved. You should tread
lightly and avoid damage to the environment.
You should know your vehicles abilities and be
able to recover it if something goes wrong. You
should never stop or shut a vehicle off when
crossing deep water unless you ingested water
into the engine air intake. If the engine stalls, do
not attempt to restart it. Determine if it has
ingested water first. The key to any crossing is
low and slow. You want to use low (L Off-Road
[if equipped] ) with the 4WD LOCK engaged
and proceed very slowly with a constant slow
speed (3-5 mph [5–8 km/h] maximum) and light
throttle. Keep the vehicle moving; do not try to
accelerate through the crossing. After crossing
any water higher than the bottom of the axle
differentials, you should inspect all of the ve-
hicle fluids for signs of water ingestion.
CAUTION!
Water ingestion into the transaxle, transfer
case, engine or vehicle interior can occur if
you drive too fast or through too deep of
