Infotainment System 183
Global Positioning
System (GPS)
If equipped, the position of the
vehicle is determined by using
satellite signals, various
vehicle signals, and map data.
At times, other interference
such as the satellite condition,
road configuration, condition
of the vehicle, and/or other
circumstances can affect the
navigation system's ability to
determine the accurate
position of the vehicle.
The GPS shows the current
position of the vehicle using
signals sent by GPS satellites.
When the vehicle is not
receiving signals from the
satellites, a symbol appears in
the status bar.
This system might not be
available or interference can
occur if any of the following
are true:
.Signals are obstructed by
tall buildings, trees, large
trucks, or a tunnel.
.Satellites are being repaired
or improved.
For more information if the
GPS is not functioning
properly, see Problems with
Route Guidance 0184 and
If the System Needs Service
0 184.
Vehicle Positioning
At times, the position of the
vehicle on the map could be
inaccurate due to one or more
of the following reasons:
.The road system has
changed.
.The vehicle is driving on
slippery road surfaces such
as sand, gravel, or snow.
.The vehicle is traveling on
winding roads or long,
straight roads.
.The vehicle is approaching a
tall building or a large
vehicle.
.The surface streets run
parallel to a freeway.
.The vehicle has been
transferred by a vehicle
carrier or a ferry.
.The current position
calibration is set incorrectly.
.The vehicle is traveling at
high speed.
.The vehicle changes
directions more than once,
or the vehicle is turning on a
turn table in a parking lot.
.The vehicle is entering
and/or exiting a parking lot,
garage, or a lot with a roof.
.The GPS signal is not
received.
.A roof carrier is installed on
the vehicle.
.Tire chains are installed on
the vehicle.
.The tires are replaced
or worn.
.The tire pressure for the
tires is incorrect.
.This is the first navigation
use after the map data is
updated.

steering maneuvers and
braking while on ice.
.Turn off cruise control.
.Select All-Wheel Drive (AWD)
Mode for vehicles equipped
with AWD. Select Snow/Ice
Mode for FWD only vehicles.
See Driver Mode Control
0292 and
All-Wheel Drive 0286.
Cold Weather Mode
In very low temperatures, a
cold weather message may
display on the Driver
Information Center (DIC). The
engine speed, transmission
shift patterns, and cabin fan
speed may operate differently
to enable the vehicle to warm
up quicker. You can manually
override the cabin fan speed in
cold weather mode.
Blizzard Conditions
Stop the vehicle in a safe
place and signal for help. Stay
with the vehicle unless there is
help nearby. If possible, use Roadside Assistance. See

everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine
exhaust under the vehicle.
This may cause exhaust
gases to get inside. Engine
exhaust contains carbon
monoxide (CO), which cannot
be seen or smelled. It can
cause unconsciousness and
even death.
If the vehicle is stuck
in snow:
.Clear snow from the base
of the vehicle, especially
any blocking the
exhaust pipe.
(Continued)
Warning (Continued)
.Open a window about
5 cm (2 in) on the vehicle
side that is away from the
wind, to bring in fresh air.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to circulate the air
inside the vehicle and set
the fan speed to the
highest setting. See
“Climate Control Systems.”
For more information about
CO, see Engine Exhaust
0 271.
To save fuel, run the engine
for short periods to warm the
vehicle and then shut the
engine off and partially close
the window. Moving about to
keep warm also helps.
If it takes time for help to
arrive, when running the
engine, push the accelerator
pedal slightly so the engine

runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle
and to signal for help with the
headlamps. Do this as little as
possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle
when stuck in sand, mud, ice,
or snow.
The Traction Control System
(TCS) can often help to free a
stuck vehicle. See Traction
Control/Electronic Stability
Control0290.
If TCS cannot free the vehicle,
turn TCS off and use the
rocking method. See “Rocking
the Vehicle to Get it Out”
following.
{Warning
If the vehicle's tires spin at
high speed, they can
explode, and you or others

Warning (Continued)
could be injured. The vehicle
can overheat, causing an
engine compartment fire or
other damage. Spin the
wheels as little as possible
and avoid going above
56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left
and right to clear the area
around the front wheels. Turn
off any traction system. Shift
back and forth between
R (Reverse) and a low forward
gear, spinning the wheels as
little as possible. To prevent
transmission wear, wait until
the wheels stop spinning
before shifting gears. Release
the accelerator pedal while
shifting, and press lightly on
the accelerator pedal when
the transmission is in gear.
Slowly spinning the wheels in
the forward and reverse directions causes a rocking
motion that could free the
vehicle. If that does not get
the vehicle out after a few
tries, it might need to be
towed out. If the vehicle does
need to be towed out, see

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

braking when passing a
vehicle or performing a lane
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)

Side Blind Zone
Alert (SBZA)
If equipped, the SBZA system
is a lane-changing aid that
assists drivers with avoiding
crashes that occur with
moving vehicles in the side
blind zone, or blind spot areas.
When the vehicle is in a
forward gear, the left or right
side mirror display will light up
if a moving vehicle is detected
in that blind zone. If the turn
signal is activated and a
vehicle is also detected on the
same side, the display will flash
as an extra warning not to
change lanes. Since this
system is part of the Lane
Change Alert (LCA) system,
read the entire LCA section
before using this feature.
Lane Change
Alert (LCA)
If equipped, the LCA system is
a lane-changing aid that
assists drivers with avoiding
lane change crashes that occur with moving vehicles in
the side blind zone (or spot)
areas or with vehicles rapidly
approaching these areas from
behind. The LCA warning
display will light up in the
corresponding outside mirror
and will flash if the turn signal
is on.
{Warning
LCA does not alert the
driver to vehicles outside of
the system detection zones,
pedestrians, bicyclists,
or animals. It may not
provide alerts when
changing lanes under all
driving conditions. Failure to
use proper care when
changing lanes may result in
injury, death, or vehicle
damage. Before making a
lane change, always check
mirrors, glance over your
shoulder, and use the turn
signals.
