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 af f ected
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 af f ected
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. 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.
