odometer needs to be repaired or serviced, the repair
technician should leave the odometer reading the same
as it was before the repair or service. If s/he cannot do so,
then the odometer must be set at zero, and a sticker must
be placed in the door jamb stating what the mileage was
before the repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/
service, so that you can be sure that it is properly reset, or
that the door jamb sticker is accurate if the odometer
must be reset at zero.
This also displays Trip A and Trip B, DTE, MPG or
L/100km, OAT (Outside Air Temperature) information to
Base Cluster, use STEP and RESET button (on steering

2. Fully depress the accelerator pedal, slowly, three times
within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE:If the indicator message illuminates when you

The Electronic Vehicle Information Center (EVIC) fea-
tures a driver-interactive display that is located in the
instrument cluster. For further information, refer to
“Electronic Vehicle Information Center (EVIC)”.
7. Anti-Lock Brake (ABS) Light This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds. If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.
8. Tire Pressure Monitoring Telltale Light — If
Equipped
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the

When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the Electronic Range
Select (ERS) shift control (described below) to select a
lower gear range. Under these conditions, using a lower
gear range will improve performance and extend trans-
mission life by reducing excessive shifting and heat
buildup.
During cold temperatures, transmission operation may
be modified depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch is inhibited until the transmission fluid
is warm (refer to the “Note” under “Torque Converter
Clutch” in this section). During extremely cold tempera-
tures (-16°F [-27°C] or below), operation may briefly belimited to third gear only. Normal operation will resume
once the transmission temperature has risen to a suitable
level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in third gear regardless of which forward gear is selected.
PARK, REVERSE, and NEUTRAL will continue to oper-
ate. The Malfunction Indicator Light (MIL) may be illu-
minated. Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service without dam-
aging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.

STARTING AND OPERATING 431

2. Shift the transmission into PARK.
3. Turn the engine OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE:Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the shift
lever is in the DRIVE position. For example, if you shift
the transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gear normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Tapping the shift
lever to the left (-) will activate ERS mode, display the
current gear in the instrument cluster, and maintain that
gear as the top available gear. Once in ERS mode, tapping
the shift lever to the left (-) or right (+) will change the top
available gear.
432 STARTING AND OPERATING

“Electronic Vehicle Information Center (EVIC)” in ”Un-
derstanding Your Instrument Panel” for further informa-
tion. Tighten the gas cap until aclickingsound is heard.
This is an indication that the gas cap is properly tight-
ened.
Press the odometer reset button to turn the message off.
If the problem persists, the message will appear the next
time the vehicle is started. This might indicate a damaged
cap. If the problem is detected twice in a row, the system
will turn on the MIL. Resolving the problem will turn the
MIL light off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration. For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Turn the ignition switch to the ON position, but do not
crank or start the engine.

MAINTENANCE SCHEDULE
The Scheduled Maintenance services listed in this
manual must be done at the times or mileages specified
to protect your vehicle warranty and ensure the best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions, such as dusty areas and very short trip
driving. Inspection and service should also be done
anytime a malfunction is suspected.
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
On Electronic Vehicle Information Center (EVIC)
equipped vehicles, “Oil Change Required” will be dis-
played in the EVIC and a single chime will sound,
indicating that an oil change is necessary.On Non-EVIC equipped vehicles, “Change Oil” will flash
in the instrument cluster odometer and a single chime
will sound, indicating that an oil change is necessary.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel usage will
influence when the “Change Oil” message is displayed.
Depending on operating conditions, the message may
appear as early as 3,500 miles (5 630 km) since last reset.
Have your vehicle serviced as soon as possible, within
the next 500 miles (805 km).
