148 Infotainment System
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 0148 and
If the System Needs Service 0149.
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.
.The 12-volt battery has been disconnected
for several days.
.The vehicle is driving in heavy traffic
where driving is at low speeds, and the
vehicle is stopped and started repeatedly.
Problems with Route Guidance
Inappropriate route guidance can occur
under one or more of the following
conditions:
.The turn was not made on the road
indicated.
.Route guidance might not be available
when using automatic rerouting for the
next right or left turn.
.The route might not be changed when
using automatic rerouting.
.There is no route guidance when turning
at an intersection.
.Plural names of places might be
announced occasionally.
.It could take a long time to operate

Driving and Operating 183
To gain more ground clearance if needed, it
may be necessary to remove the front fascia
lower air dam. However, driving without the
air dam reduces fuel economy.
Caution
Operating the vehicle for extended
periods without the front fascia lower air
dam installed can cause improper airflow
to the engine. Reattach the front fascia
air dam after off-road driving.
Loading the Vehicle for Off-Road Driving
{Warning
.Unsecured cargo on the load floor can
be tossed about when driving over
rough terrain. You or your passengers
can be struck by flying objects. Secure
the cargo properly.
.Keep cargo in the cargo area as far
forward and as low as possible. The
heaviest things should be on the floor,
forward of the rear axle.
.Heavy loads on the roof raise the
vehicle's center of gravity, making it
more likely to roll over. You can be(Continued)
Warning (Continued)
seriously or fatally injured if the
vehicle rolls over. Put heavy loads
inside the cargo area, not on the roof.
For more information about loading the
vehicle, see Vehicle Load Limits 0188.
Environmental Concerns
.Always use established trails, roads, and
areas that have been set aside for public
off-road recreational driving and obey all
posted regulations.
.Do not damage shrubs, flowers, trees,
or grasses or disturb wildlife.
.Do not park over things that burn. See
Parking over Things That Burn 0198.
Driving on Hills
Driving safely on hills requires good
judgment and an understanding of what the
vehicle can and cannot do.
{Warning
Many hills are simply too steep for any
vehicle. Driving up hills can cause the
vehicle to stall. Driving down hills can
(Continued)
Warning (Continued)
cause loss of control. Driving across hills
can cause a rollover. You could be injured
or killed. Do not drive on steep hills.
Before driving on a hill, assess the
steepness, traction, and obstructions. If the
terrain ahead cannot be seen, get out of the
vehicle and walk the hill before driving
further.
When driving on hills:
.Use a low gear and keep a firm grip on
the steering wheel.
.Maintain a slow speed.
.When possible, drive straight up or down
the hill.
.Slow down when approaching the top of
the hill.
{Warning
Driving to the top of a hill at high speed
can cause a crash. There could be a
drop-off, embankment, cliff, or even
another vehicle. You could be seriously
injured or killed. As you near the top of a
hill, slow down and stay alert.

Improper use of the heater cord or an
extension cord can damage the cord and
may result in overheating and fire.
.Plug the cord into a three-prong
electrical utility receptacle that is
protected by a ground fault detection
function. An ungrounded outlet could
cause an electric shock.
.Use a weatherproof, heavy-duty,
15 amp-rated extension cord if needed.
Failure to use the recommended
extension cord in good operating
condition, or using a damaged heater
or extension cord, could make it
overheat and cause a fire, property
damage, electric shock, and injury.
.Do not operate the vehicle with the
heater cord permanently attached to
the vehicle. Possible heater cord and
thermostat damage could occur.
.While in use, do not let the heater
