Performance and
Maintenance
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) that limits wheel spin
and the StabiliTrak/Electronic
Stability Control (ESC) system that
assists with directional control of the
vehicle in difficult driving conditions.
Both systems come on
automatically when the vehicle is
started and begins to move.
.To turn off TCS, press and
release
gon the center stack.
The traction off light
idisplays
in the instrument cluster. The
appropriate Driver Information
Center (DIC) message displays.
. To turn off both TCS and
StabiliTrak/ESC, press and hold
guntiliandgilluminate in the instrument cluster and the
appropriate DIC message
displays.
. Press and release
gagain to
turn on both systems.
StabiliTrak/ESC will automatically
turn on if the vehicle exceeds
56 km/h (35 mph). Traction control
will remain off.
See Traction Control/Electronic
Stability Control 0273.
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
0238. 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
0 380.
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 0381.

FlexFuel Possible
Certain models are compatible with
E85 fuel. See E85 or FlexFuel
0 291.
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) 0154 or
Driver Information Center (DIC)
(Uplevel) 0156. 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) 0154 or
Driver Information Center (DIC)
(Uplevel) 0156.
2. Fully press the accelerator pedal slowly three times within
five seconds.
3. If the display changes to 100%, the system is reset.

{Warning
Leaving children in a vehicle with
the ignition key is dangerous and
children or others could be
seriously injured or killed. They
could operate the power windows
or other controls or make the
vehicle move. The windows will
function with the keys in the
ignition, and children or others
could be caught in the path of a
closing window. Do not leave
children in a vehicle with the
ignition key.

{Warning
If the key is unintentionally
rotated while the vehicle is
running, the ignition could be
moved out of the RUN position.
This could be caused by heavy
items hanging from the key ring,
or by large or long items attached
to the key ring that could be
contacted by the driver or
steering wheel. If the ignition
moves out of the RUN position,
the engine will shut off, braking
and steering power assist may be(Continued)

impacted, and airbags may not
deploy. To reduce the risk of
unintentional rotation of the
ignition key, do not change the
way the ignition key and Remote
Keyless Entry (RKE) transmitter,
if equipped, are connected to the
provided key rings.
The ignition key and key rings, and
RKE transmitter, if equipped, are
designed to work together as a
system to reduce the risk of
unintentionally moving the key out
of the RUN position. The ignition
key has a small hole to allow
attachment of the provided key ring.
It is important that any replacement
ignition keys have a small hole. See
your dealer if a replacement key is
required.
The combination and size of the
rings that came with your keys were
specifically selected for your
vehicle. The rings are connected to
the key like two links of a chain to reduce the risk of unintentionally
moving the key out of the RUN
position. Do not add any additional
items to the ring attached to the
ignition key. Attach additional items
only to the second ring, and limit
added items to a few essential keys
or small, light items no larger than
an RKE transmitter.
