Rear Wiper Arm Assembly
Protection
When using an automatic car wash,
move the rear wiper control to OFF
to disable the rear wiper. In some
vehicles, if the transmission is in
N (Neutral) and the vehicle speed is
very slow, the rear wiper will
automatically park under the rear
spoiler.
The wiper operations return to
normal when the transmission is no
longer in N (Neutral) or the vehicle
speed has increased.
Reverse Gear Wipes
If the rear wiper control is off, the
rear wiper will automatically operate
continuously when the shift lever is
in R (Reverse), and the front
windshield wiper is performing low
or high speed wipes. If the rear
wiper control is off, the shift lever is
in R (Reverse), and the front
windshield wiper is performing interval wipes, then the rear wiper
automatically performs interval
wipes.
This feature can be turned on or off.
See Vehicle Personalization 0 158 .
The windshield washer reservoir is
used for the windshield and the rear
window. Check the fluid level in the
reservoir if either washer is not
working. See Washer Fluid 0 296 .
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, StabiliTrak,
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.

If coolant is visible but the coolant
level is not at or above the full cold
mark, see “ How to Add Coolant to
the Coolant Surge Tank, ” following.
How to Add Coolant to the
Coolant Surge Tank
{ WarningSpilling coolant on hot engine
parts can burn you. Coolant
contains ethylene glycol and it will
burn if the engine parts are hot
enough.
{ Warning
Plain water, or other liquids such
as alcohol, can boil before the
proper coolant mixture will. With
plain water or the wrong mixture,
the engine could get too hot but
there would not be an overheat
(Continued) Warning (Continued) warning. The engine could catch
fire and you or others could be
burned.
{ WarningSteam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure
cap, even a little, can cause them
to come out at high speed and
you could be burned. Never turn
the cap when the cooling system,
including the pressure cap, is hot.
Wait for the cooling system and
pressure cap to cool.
Caution
Failure to follow the specific
coolant fill procedure could cause
the engine to overheat and could
(Continued) Caution (Continued) cause system damage. If coolant
is not visible in the surge tank,
contact your dealer.
If no coolant is visible in the surge
tank, add coolant.
1. Remove the coolant surge tank
pressure cap when the cooling
system, including the coolant
surge tank pressure cap and
upper radiator hose, is no
longer hot.
Turn the pressure cap slowly
counterclockwise about one full
turn. If a hiss is heard, wait for
that to stop. A hiss means
there is still some pressure left.
2. Keep turning the pressure cap
slowly, and remove it.
