Caution
A transmission hot message
may display if the automatic
transmission fluid is too hot.
Driving under this condition
can damage the vehicle.
Stop and idle the engine to
cool the automatic
transmission fluid. This
message clears when the
transmission fluid has cooled
sufficiently.
D : This position is for normal
driving. If more power is
needed for passing, press the
accelerator pedal down.
Downshifting the transmission
in slippery road conditions
could result in skidding. See
“Skidding” under Loss of
Control 0237. M :
This mode can be entered
by moving the shift lever from
D (Drive) to M (Manual Mode).
M (Manual Mode) allows the
driver to select gears
appropriate for current driving
conditions. M (Manual Mode)
can be exited by returning the
shift lever to D (Drive). See
Manual Mode (Electronic
Shifter) 0281 or
Manual Mode (Mechanical
Shifter) 0280.
Caution
Spinning the tires or holding
the vehicle in one place on a
hill using only the
accelerator pedal may
damage the transmission.
The repair will not be
covered by the vehicle
warranty. If the vehicle is
stuck, do not spin the tires.
When stopping on a hill, use
the brakes to hold the
vehicle in place. While in Sport or Track Mode,
the vehicle monitors driving
behavior, and automatically
enables Performance Shift
Features when spirited driving
is detected. These features
maintain lower transmission
gears to increase available
engine braking and improve
acceleration response. The
vehicle will exit these features
and return to Sport or Track
Mode normal operation after a
short period when no spirited
driving is detected. See Driver
Mode Control
0292.
Engine speeds may be
increased while driving at
highway speeds while the
engine is still warming up.

{Warning
Do not rely on this feature.
It does not replace the need
to pay attention and drive
safely. You may not hear or
feel alerts or warnings
provided by this system.
Failure to use proper care
when driving may result in
injury, death, or vehicle
damage.
When Automatic Vehicle Hold
(AVH) is turned on and the
vehicle is braked to a stop,
AVH prevents the vehicle from
moving during the transition
from brake pedal release to
accelerator pedal apply. The
brakes release when the
accelerator pedal is applied.
The brakes may also release
under other conditions. Do not
rely on AVH to hold the
vehicle.
If the accelerator pedal is not
applied within a few minutes,
the Electric Parking Brake will apply. The parking brake will
also apply if the driver door is
opened or the driver seat belt
is unfastened while AVH is
holding the vehicle.
AVH can be turned on by
pressing AUTO HOLD. The
indicator light on the switch
will come on. The AVH light on
the instrument panel will come
on while AVH is actively
holding the vehicle. See
Automatic Vehicle Hold (AVH)
Light
0122.
Ride Control
Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction
Control System (TCS) and
StabiliTrak/Electronic Stability
Control (ESC). These systems
help limit wheel slip and assist the driver in maintaining
control, especially on slippery
road conditions.
TCS activates if it senses that
any of the drive wheels are
spinning or beginning to lose
traction. When this happens,
the system brakes the
spinning wheel(s) and/or
reduces engine power to limit
wheel spin.
StabiliTrak/ESC activates
when the computer senses a
difference between the
intended path and the
direction the vehicle is actually
traveling. StabiliTrak/ESC
selectively applies braking
pressure at any one of the
vehicle's brakes to help steer
the vehicle in the intended
direction.
If cruise control is being used
and TCS or StabiliTrak/ESC
begins to limit wheel spin,
cruise control will disengage.
Cruise control may be turned
back on when road conditions
allow.

the selected following gap. To
disengage ACC, apply the
brake. If the Traction Control
System (TCS) or StabiliTrak/
Electronic Stability Control
(ESC) system activates while
ACC is engaged, ACC may
automatically disengage. See
Traction Control/Electronic
Stability Control0290. When
road conditions allow ACC to
be safely used, ACC can be
turned back on. ACC will not
engage if the TCS or
StabiliTrak/ESC electronic
stability control system is
disabled.
ACC can reduce the need for
you to frequently brake and
accelerate, especially when
used on expressways,
freeways, and interstate
highways. When used on other
roads, you may need to take
over the control of braking or
acceleration more often.{Warning
ACC has limited braking
ability and may not have
time to slow the vehicle
down enough to avoid a
collision with another vehicle
you are following. This can
occur when vehicles
suddenly slow or stop
ahead, or enter your lane.
Also see “Alerting the
Driver” in this section.
Complete attention is
always required while driving
and you should be ready to
take action and apply the
brakes. See Defensive
Driving 0235.
{Warning
ACC will not detect or brake
for children, pedestrians,
animals, or other objects.
Do not use ACC when:
.On winding and hilly roads
or when the sensors are
blocked by snow, ice,
or dirt. The system may
not detect a vehicle
ahead. Keep the entire
front of the vehicle clean.
.Visibility is low, such as in
fog, rain, or snow
conditions. ACC
performance is limited
under these conditions.
.On slippery roads where
fast changes in tire
traction can cause
excessive wheel slip.
.When towing a trailer.

Approaching and Following a
Vehicle
The vehicle ahead indicator is
in the instrument cluster and
HUD display, if equipped.
The vehicle ahead indicator
only displays when a vehicle is
detected in your vehicle’s path
moving in the same direction.
If this symbol is not displaying,
ACC will not respond to or
brake to vehicles ahead.
ACC automatically slows the
vehicle down and adjusts
vehicle speed to follow a
detected vehicle ahead at the
selected follow gap. The
vehicle speed increases or
decreases to follow a
detected vehicle in front of
your vehicle when that vehicle
is traveling slower than yourvehicle set speed. It may apply
limited braking, if necessary.
When braking is active, the
brake lamps will come on. The
automatic braking may feel or
sound different than if the
brakes were applied manually.
This is normal.
Passing a Vehicle While
Using ACC
If the set speed is high
enough, and the left turn
signal is used to pass a vehicle
ahead in the selected
following gap, ACC may assist
by gradually accelerating the
vehicle prior to the lane
change.
{Warning
When using ACC to pass a
vehicle or perform a lane
change, the following
distance to the vehicle being
passed may be reduced.
ACC may not apply
sufficient acceleration or

change. Always be ready to
manually accelerate or brake
to complete the pass or lane
change.
Stationary or Very
Slow-Moving Objects
{Warning
ACC may not detect and
react to stopped or
slow-moving vehicles ahead
of you. For example, the
system may not brake for a
vehicle it has never detected
moving. This can occur in
stop-and-go traffic or when
a vehicle suddenly appears
due to a vehicle ahead
changing lanes. Your vehicle
may not stop and could
cause a crash. Use caution
when using ACC. Your (Continued)
