washer fluid and activate the wipers.

windshield washer had been
activated. See Washer Fluid 0 334
for information on filling the
windshield washer fluid reservoir.
{ Warning
In freezing weather, do not use
the washer until the windshield is
warmed. Otherwise the washer
fluid can form ice on the
windshield, blocking your vision.
Clear snow and ice from the wiper
blades before using them. If frozen
to the windshield, carefully loosen or thaw them. Damaged blades should
be replaced. See Wiper Blade
Replacement 0 344 .
Heavy snow or ice can overload the
wiper motor.
Wipe Parking
If the ignition is turned off while the
wipers are on LO, HI, or
3 , they
will immediately stop.
If the windshield wiper control is
then moved to OFF before the driver
door is opened or within 10 minutes,
the wipers will restart and move to
the base of the windshield.
If the ignition is turned off while the
wipers are performing wipes due to
windshield washing, the wipers
continue to run until they reach the
base of the windshield.
Compass The vehicle may have a compass
display on the Driver Information
Center (DIC). The compass receives
its heading and other information
from the Global Positioning System (GPS) antenna, Electronic
Stability Control (ESC), and vehicle
speed information.
The compass system is designed to
operate for a certain number of
miles or degrees of turn before
needing a signal from the GPS
satellites. When the compass
display shows CAL, drive the
vehicle for a short distance in an
open area where it can receive a
GPS signal. The compass system
will automatically determine when a
GPS signal is restored and provide
a heading again.
Clock The time and date for the clock can
be set using the infotainment
system. See “ Time/Date ” in
“ System “ under “ Settings ” in the
infotainment manual.
Power Outlets Accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone, MP3
player, etc.
