or the session is terminated,
the voice recognition dialog
stops.
An example of this type of
manual intervention is
touching an entry of a
displayed number list instead
of speaking the number
associated with the entry
desired.
Canceling Voice
Recognition
.Touch or say“Cancel”or
“Exit” to terminate the voice
recognition session and
show the display where
voice recognition was
initiated.
.Pression the steering
wheel controls to terminate
the voice recognition
session and show the display

initiated.
Natural Language Commands
Most languages do not
support natural language
commands in sentence form. For those languages, use
direct commands like the
examples shown on the
display.
Helpful Hints for Speaking
Commands
Voice recognition can
understand commands that
are naturally stated in
sentence form or direct
commands that state the
application and the task.
For best results:
.Listen for the prompt before
saying a command or reply.
.Speak the command
naturally, not too fast, not
too slow.
.Use direct commands
without a lot of extra words.
For example,
“Call at
work,” “Play” followed by the
artist or song name,
or “Tune” followed by the
radio station number.
.Navigation destinations can
be made in a single
command using keywords. A few examples are:
“I want
directions to an address,” “I
need to find a place of
interest or (POI),” or“Find
contact.”
The system responds by
requesting more details. For
other POIs, say the name of
a category like
“Restaurants,” “Shopping
Malls,” or“Hospitals.”
.Navigating to a destination
outside of the current
country takes more than one
command. The first
command is to tell the
system where the navigation
will take place, such as an
Address, Intersection, POI,
or Contact. If Address or
Intersection is selected, the
second command is to say,
“Change Country.” Once the
system responds, say the
country before saying the
rest of the address and/or
intersection.

system is off, a noticeable
change in pedal force and
travel may be felt. This is
normal.

Launch Control will initially
limit engine speed as you
rapidly apply the accelerator
pedal to wide open throttle.
Allow the engine rpm to
stabilize. A smooth, quick

PTM, and Launch Control are
systems designed for a closed
course race track and not
intended for public roads. The
systems are not intended to
compensate for lack of driver
experience or familiarity with
the race track.Limited-Slip
Differential
If equipped, the Electronic
Limited-Slip Differential (eLSD)
is automatically activated.
eLSD actively monitors vehicle
sensors and driver inputs to
determine the amount of
change for the conditions.
With eLSD, the vehicle has:
.Enhanced high-speed
control.
.Improved traction through
corners, allowing more
acceleration.
.More precise steering.
.Increased vehicle agility.
.Integration with StabiliTrak/
Electronic Stability
Control (ESC).
For vehicles with eLSD, driven
under severe conditions, the
rear axle fluid should be
changed. See Competitive

Maintenance Schedule 0469.
Cruise Control
{
Warning
Cruise control can be
dangerous where you
cannot drive safely at a
steady speed. Do not use
cruise control on winding
roads or in heavy traffic.
Cruise control can be
dangerous on slippery roads.
On such roads, fast changes
in tire traction can cause
excessive wheel slip, and
you could lose control. Do
not use cruise control on
slippery roads.
With cruise control, a speed of
about 40 km/h (25 mph) or
more can be maintained
without keeping your foot on
the accelerator. Cruise control
does not work at speeds
below about 40 km/h (25 mph).
If equipped with a manual
transmission, the cruise
control will remain active when
