The XM satellites are in orbit over
the equator; therefore, objects south
of the vehicle may cause satellite
reception interruptions. To help
compensate f or this, ground-based
repeaters are placed in major
metropolitan areas.
Satellite signals are more likely to be
blocked by tall buildings and
mountains the f arther north you
travel f rom the equator. Carrying
large items on a roof rack can also
block the signal.
Depending on where you drive, you
may experience reception problems.
Interf erence can be caused by any of
these conditions:Driving on the north side of an
east/west mountain road.
Driving on the north side of a
large commercial truck on an
east/west road.
Driving in tunnels. Driving on a road beside a vertical
wall, steep clif f , or hill to the south
of you.
Driving on the lower level of a
multi-tiered road.
When DPLII is turned on (see page
), sound coming f rom the rear
speakers may be distorted due to the
compression of the music being
broadcast. Turn DPLII of f if this
happens. 233

Compass operation can be affected
by driving near power lines or
stations, across bridges, through
tunnels, over railroad crossings,
past large vehicles, or driving near
large objects that can cause a
magnetic disturbance. It can also be
affected by accessories such
as antennas and roof racks that are
mounted by magnets.
When you turn the ignition switch to
the ON (II) position, the compass is
self-calibrating, then the compass
display is shown in the display.The compass may need to be
manually calibrated af ter exposure to
a strong magnetic field. If the
compassseemstobecontinually
showing the wrong direction and is
not self -calibrating, or the compass
display is blinking with the CAL
indicator on, do the f ollowing
procedure. Do this procedure in an open
area, away f rom buildings, power
lines, and other vehicles.
Turn the ignition switch to the ON
(II) position.
Press and hold the SETUP button
f or about 5 seconds. The display
shows you the compass setting
menu items.

The f ollowing f actors can lower your
vehicle’s f uel economy:
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance messages displayed on the
inf ormation display (see
on page ).
For example: Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.
Aerodynamic drag has a big ef f ect
on f uel economy at speeds above
45 mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
Idling
results in 0 miles per gallon (0 kms
per liter).
It puts a heavier
load on the engine, increasing f uel
consumption.
In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your f uel
economy. An underinf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy. 505
