Active Guidance View
When a destination is chosen and a
navigation session is active, the
navigation system enters into an
Active Guidance View (AGV).
Map Orientation
Touch
Aon the map to access map
orientation settings. Map orientation
is 3D Heading Up by default.
Available settings are:
.3D Heading Up (Default): 3D map
with the vehicle pointing up. In this
mode, the current location icon will
always head up and the map will
rotate around it.
.2D Heading Up: 2D map with the
vehicle pointing up. In this mode,
the current location icon will always

166 INFOTAINMENT SYSTEM
Manual interaction in the voice
recognition session is permitted.
Interaction during a voice session may
be completed entirely using voice
commands while some manual
commands may expedite a task. If a
selection is made using a manual
control, the voice recognition dialog
will progress in the same way as if the
selection were made using a voice
command. Once the system completes
the task, 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 where voice recognition was
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: “Iwant 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.
If POI is asked for, say “Change
Location,” then“Change Country.”
Direct commands might be more
clearly understood by the system. An
example of a direct command would
be “Call .” Examples of these
direct commands are displayed on
most of the screens while a voice

.Files including other individual files
of all media types such as songs,
audiobook chapters, podcast
episodes, and videos.
.Album type folders including types
such as albums and audiobooks.
There are no restrictions if the
number of files and albums is fewer
than 12,000. When the number of files
connected to the system is between
12,000 and 24,000, the content cannot
be accessed directly with one
command like “Play .”
The restriction is that the command
“Play Song” must be spoken first; the
system will then ask for the song
name. The reply command would be
to say the name of the song to play.
Similar limits exist for album content.
If there are more than 12,000 albums,
but fewer than 24,000, the content
cannot be accessed directly with one
command like, “Play .”
The command “Play Album”must first
be spoken; the system will then ask
for the album name. The reply would
be to say the name of the album
to play. Once the number of files has exceeded
approximately 24,000, there is no
support for accessing the songs
directly through voice commands.
There will still be access to the media
content by using commands for
playlists, artists, and genres.
The access commands for playlists,
artists, and genres are prohibited after
the number of this type of media
exceeds 12,000.
The system will provide feedback the
first time voice recognition is initiated
if it has become apparent that any of
these limits are reached during a
device initializing process.
Voice recognition performance will
degrade to some extent based on
many factors when adding large
amounts of data to recognize. If this is
the case, perhaps accessing songs
through playlists or artist name would
work better.

208 DRIVING AND OPERATING
2. Turn the steering wheel aboutone-eighth of a turn, until the right
front tire contacts the
pavement edge.
3. Turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
.Steering or Cornering Skid —too
much speed or steering in a curve
causes tires to slip and lose
cornering force.
.Acceleration Skid —too much
throttle causes the driving wheels
to spin.
Defensive drivers avoid most skids by
taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible. If the vehicle starts to slide, follow
these suggestions:
.Ease your foot off the accelerator
pedal and steer the way you want
the vehicle to go. The vehicle may
straighten out. Be ready for a
second skid if it occurs.
.Slow down and adjust your driving
according to weather conditions.
Stopping distance can be longer and
vehicle control can be affected when
traction is reduced by water, snow,
ice, gravel, or other material on the
road. Learn to recognize warning
clues
—such as enough water, ice,
or packed snow on the road to
make a mirrored surface —and
slow down when you have any
doubt.
.Try to avoid sudden steering,
acceleration, or braking, including
reducing vehicle speed by shifting
to a lower gear. Any sudden changes
could cause the tires to slide.
Remember: Antilock brakes help avoid
only the braking skid.
Off-Road Driving
All-wheel-drive vehicles can be used
for off-road driving. Vehicles without
all-wheel drive and vehicles not
equipped with All Terrain (AT) or
On-Off Road (OOR) tires must not be
driven off-road except on a level, solid
surface. To contact the tire
manufacturer for more information
about the original equipment tires, see
the warranty manual.
Controlling the vehicle is the key to
successful off-road driving. One of the
best ways to control the vehicle is to
control the speed.
{Warning
When driving off-road, bouncing
and quick changes in direction can
easily throw you out of position.
This could cause you to lose control
and crash. You and your passengers
should always wear seat belts.
Before Driving Off-Road
.Have all necessary maintenance and
service work completed.

212 DRIVING AND OPERATING
Caution
Do not drive through standing
water if it is deep enough to cover
the wheel hubs, axles, or exhaust
pipe. Deep water can damage the
axle and other vehicle parts.
If the standing water is not too deep,
drive through it slowly. At faster
speeds, water can get into the engine
and cause it to stall. Stalling can
occur if the exhaust pipe is under
water. Do not turn off the ignition
when driving through water. If the
exhaust pipe is under water, the
engine will not start. When going
through water, the brakes get wet and
it may take longer to stop. See Driving
on Wet Roads 0212.
After Off-Road Driving
Remove any brush or debris that has
collected on the underbody or chassis,
or under the hood. These
accumulations can be a fire hazard.
After operation in mud or sand, have
the brake linings cleaned and checked.
These substances can cause glazing
and uneven braking. Check the body structure, steering, suspension,
wheels, tires, and exhaust system for
damage and check the fuel lines and
cooling system for any leakage.
More frequent maintenance service is
required. See
Maintenance Schedule
0 358.
Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop
and accelerate. Always drive slower in
these types of driving conditions and
avoid driving through large puddles
and deep-standing or flowing water.
{Warning
Wet brakes can cause crashes. They
might not work as well in a quick
stop and could cause pulling to one
side. You could lose control of the
vehicle.
After driving through a large puddle
of water or a car/vehicle wash,
lightly apply the brake pedal until
the brakes work normally.
(Continued)
Warning (Continued)
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be very
cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can
build up under the vehicle's tires so
they actually ride on the water. This
can happen if the road is wet enough
and you are going fast enough. When
the vehicle is hydroplaning, it has
little or no contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.

310 VEHICLE CARE
Winter Tires
This vehicle was not originally
equipped with winter tires. Winter
tires are designed for increased
traction on snow and ice-covered
roads. Consider installing winter tires
on the vehicle if frequent driving on
ice or snow covered roads is expected.
See your dealer for details regarding
winter tire availability and proper tire
selection. Also, seeBuying New Tires
0 325.
With winter tires, there may be
decreased dry road traction, increased
road noise, and shorter tread life.
After changing to winter tires, be alert
for changes in vehicle handling and
braking.
If using winter tires:
.Use tires of the same brand and
tread type on all four wheel
positions.
.Use only radial ply tires of the same
size, load range, and speed rating as
the original equipment tires.
Winter tires with the same speed
rating as the original equipment tires
may not be available for H, V, W, Y, and ZR speed rated tires. If winter
tires with a lower speed rating are
chosen, never exceed the tire's
maximum speed capability.
Summer Tires
This vehicle may come with
235/55R18 or 245/45R20 high
performance summer tires. These tires
have a special tread and compound
that are optimized for maximum dry
and wet road performance. This
special tread and compound will have
decreased performance in cold
climates, and on ice and snow. It is
recommended that winter tires be
installed on the vehicle if frequent
driving at temperatures below
approximately 5 °C (40 °F) or on ice or
snow covered roads is expected. See
Winter Tires
0310.
Caution
High performance summer tires
have rubber compounds that lose
flexibility and may develop surface
cracks in the tread area at
temperatures below −7 °C (20 °F).
(Continued)
Caution (Continued)
Always store high performance
summer tires indoors and at
temperatures above −7 °C (20 °F)
when not in use. If the tires have
been subjected to −7 °C (20 °F) or
less, let them warm up in a heated
space to at least 5 °C (40 °F) for
24 hours or more before being
installed or driving a vehicle on
which they are installed. Do not
apply heat or blow heated air
directly on the tires. Always inspect
tires before use. See Tire Inspection
0 322.
Tire Sidewall Labeling
