28 In Brief
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits0212. 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 the
tire 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
0 345.
Tire Fill Alert (If Equipped)
This feature provides visual and
audible alerts outside the vehicle to
help when inflating an underinflated
tire to the recommended cold tire
pressure. See “Tire Fill Alert (If
Equipped)” underTire Pressure
Monitor Operation 0346.Fuel
Regular Fuel
Use only unleaded gasoline rated
87 octane or higher in your vehicle.
Do not use gasoline with an octane
rating lower as it may result in
vehicle damage and lower fuel
economy. See Fuel0266.
E85 or FlexFuel
FlexFuel Possible
Certain models are compatible with
E85 fuel. See E85 or FlexFuel
0 268.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and, on most vehicles, 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
To reset the engine oil life system:
1. Display OIL LIFE REMAINING on the DIC.
See Driver Information Center
(DIC) (Base Level) 0161 or
Driver Information Center (DIC)
(Uplevel) 0162. If the vehicle
does not have DIC buttons, the
vehicle must be in P (Park) to
access this display.
2. Press and hold
Von the DIC,
or the trip odometer reset stem
if the vehicle does not have
DIC buttons, for several
seconds. The oil life will
change to 100%.

The oil life system can also be reset
as follows:1. Display OIL LIFE REMAINING on the DIC.
See Driver Information Center
(DIC) (Base Level) 0161 or
Driver Information Center (DIC)
(Uplevel) 0162.
2. Fully press the accelerator pedal slowly three times within
five seconds.
3. If the display changes to 100%, the system is reset.
See Engine Oil Life System 0299.

English
When the ignition is on, the fuel
gauge indicates about how much
fuel is left in the tank.
There is an arrow near the fuel
gauge pointing to the side of the
vehicle the fuel door is on.
When the indicator nears empty, the
low fuel light comes on. There still is
a little fuel left, but the vehicle
should be refueled soon. Here are four things that some
owners ask about. None of these
show a problem with the fuel gauge:
.
At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
. The gauge moves a little while
turning a corner or speeding up.
. The gauge takes a few seconds
to stabilize after the ignition is
turned on, and goes back to
empty when the ignition is
turned off.

English
The engine oil pressure gauge
shows the engine oil pressure
in kPa (kilopascals) or psi (pounds
per square inch) when the engine is
running.
Oil pressure can vary with engine
speed, outside temperature, coolant
temperature, and oil viscosity.
On some models, the oil pump will
vary engine oil pressure according
to engine needs. Oil pressure may
change quickly as the engine speed
or load varies. This is normal. If the
oil pressure warning light or Driver
Information Center (DIC) message indicates oil pressure outside the
normal operating range, check the
vehicle's oil as soon as possible.
See
Engine Oil 0297.
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil.

Remaining Oil Life
Turn the trip odometer reset stem
until REMAINING OIL LIFE
displays. An estimate of the oil's
remaining useful life is shown.
REMAINING OIL LIFE 99% means
99% of the current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
The oil should be changed as soon
as possible. SeeEngine Oil0297.
In addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended in the Maintenance
Schedule. See Maintenance
Schedule 0389.
The Oil Life display must be reset
after each oil change. It will not
reset itself. Do not reset the Oil Life
display at any time other than when
the oil has just been changed.
It cannot be reset accurately until
the next oil change. To reset the
engine oil life system, see Engine
Oil Life System 0299. Transmission Fluid Temperature
The temperature of the automatic
transmission fluid displays in either
degrees Celsius (°C) or degrees
Fahrenheit (°F).
Trailer Brake
On vehicles with the Integrated
Trailer Brake Control (ITBC) system,
turn the trip odometer reset stem
until TRAILER GAIN and TRAILER
OUTPUT displays.
TRAILER GAIN shows the Trailer
Gain setting. This setting can be
adjusted from 0.0 to 10.0 with either
a trailer connected or disconnected.
TRAILER OUTPUT shows the
power output to the trailer anytime a
trailer with electric brakes is
connected. Output is displayed as a
bar graph. Dashes may appear in
the TRAILER OUTPUT display if a
trailer is not connected.
Hourmeter
This display shows the total number
of hours the engine has run.
Unit
This will change the displays on the
instrument cluster and DIC to either
metric or English (US)
measurements. To change the units,
press the trip odometer reset stem
when UNITS is displayed to enter
the Unit menu. Turn the trip
odometer reset stem to switch
between English and metric. Press
the trip odometer reset stem when
the desired setting is displayed.
Compass
The vehicle may have a compass in
the Driver Information Center (DIC).
See
Compass 0136.
Driver Information Center
(DIC) (Uplevel)
The DIC displays are shown in the
center of the instrument cluster in
the Info app. See Instrument Cluster
0 143. The displays show the status
of many vehicle systems. The
controls for the DIC are on the right
steering wheel control.
