Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9-9.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that thetire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System
on page 10-52.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays a DIC message when
it is necessary to change the engine
oil and filter. The oil life system
should be reset to 100% only
following an oil change.
Resetting the Oil Life System
1. Turn the ignition to ON/RUN, with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
3. Turn the key to LOCK/OFF. See
Engine Oil Life System on
page 10-9.
E85 or FlexFuel
Vehicles with a yellow fuel cap can
use either unleaded gasoline or
ethanol fuel containing up to 85%
ethanol (E85). See E85 or FlexFuel
on page 9-40. For all other vehicles,
use only the unleaded gasoline
described under Fuel on page 9-39.
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible.
.Avoid fast starts and accelerate
smoothly.
.Brake gradually and avoid
abrupt stops.
.Avoid idling the engine for long
periods of time.

U(Customization):Press this
button to customize the feature
settings on the vehicle. See Vehicle
Personalization on page 5-37 for
more information.
V(Set/Reset): Press this button to
set or reset certain functions and to
turn off or acknowledge messages
on the DIC.
Trip/Fuel Menu Items
3(Trip/Fuel): Press this button
to scroll through the following menu
items:
Odometer
Press
3until XX km (mi)
displays. This display shows the
distance the vehicle has been
driven in either kilometers (km) or
miles (mi).
Trip Odometers
Press
3until A or B displays.
This display shows the current
distance traveled in either
kilometers (km) or miles (mi) since
the last reset for each trip odometer.
Both trip odometers can be used at
the same time.
Each trip odometer can be reset to
zero separately by pressing
Vwhile
the desired trip odometer is
displayed. The trip odometer has a feature
called the retro-active reset. This
can be used to set the trip odometer
to the number of kilometers (miles)
driven since the ignition was last
turned on. This can be used if the
trip odometer is not reset at the
beginning of the trip.
To use the retro-active reset feature,
press and hold
Vfor at least
four seconds. The trip odometer will
display the number of
kilometers (km) or miles (mi) driven
since the ignition was last turned on
and the vehicle was moving. Once
the vehicle begins moving, the trip
odometer will accumulate mileage.
For example, if the vehicle was
driven 8 km (5 miles) before it is
started again, and then the
retro-active reset feature is
activated, the display will show 8 km
(5 miles). As the vehicle begins
moving, the display will then
increase to 8.1 km (5.1 miles),
8.2 km (5.2 miles), etc.

STARTING DISABLED
SERVICE THROTTLE
This message displays if the starting
of the engine is disabled due to the
electronic throttle control system.
Have the vehicle serviced by your
dealer immediately.
This message only appears while
the ignition is in ON/RUN, and will
not disappear until the problem is
resolved.
This message cannot be
acknowledged.
Tire Messages
CHECK TIRE PRESSURE or
TIRE LOW ADD AIR TO TIRE
If the vehicle has the Tire Pressure
Monitor System (TPMS), this
message displays when the
pressure in one or more of the tires
is low. The low tire pressure warning
light will also come on. SeeTire
Pressure Light on page 5-22. This
message will also indicate which tire
needs to be checked. You can receive more than one tire pressure
message at a time. To read the
other messages that may have been
sent at the same time, press the set/
reset button. If a tire pressure
message appears on the DIC, stop
as soon as you can. Have the tire
pressures checked and set to those
shown on the Tire Loading
Information label. See
Tires on
page 10-42, Vehicle Load Limits on
page 9-9, and Tire Pressure on
page 10-51. The DIC also shows
the tire pressure values. See Driver
Information Center (DIC) on
page 5-24.
SERVICE TIRE MONITOR
SYSTEM
If the vehicle has the Tire Pressure
Monitor System (TPMS), this
message displays if a part on the
system is not working properly. The
tire pressure light also flashes and
then remains on during the same
ignition cycle. See Tire Pressure
Light on page 5-22. Several
conditions may cause this message to appear. See
Tire Pressure
Monitor Operation on page 10-53 for
more information. If the warning
comes on and stays on, there may
be a problem with the TPMS. See
your dealer.
TIRE LEARNING ACTIVE
If the vehicle has the Tire Pressure
Monitor System (TPMS), this
message displays when the system
is re-learning the tire positions on
the vehicle. See Driver Information
Center (DIC) on page 5-24 for more
information. The tire positions must
be re-learned after rotating the tires
or after replacing a tire or sensor.
See Tire Inspection on page 10-56,
Tire Rotation on page 10-57, Tire
Pressure Monitor Operation on
page 10-53, and Tire Pressure on
page 10-51 for more information.
