It may be necessary to slide the
adjustable stop along the webbing
toward the outboard anchor to
fully tighten the seat belt around
the child restraint. While a child

Rainsense. Wiper Arm Assembly Protection
When using an automatic car wash,
move the windshield wiper lever to
OFF. This disables the automatic
Rainsense windshield wipers.
With Rainsense, if the transmission is
in N (Neutral) and the vehicle speed is
very slow, the wipers will
automatically stop at the base of the
windshield.
The wiper operations return to normal
when the transmission is no longer in
N (Neutral) or the vehicle speed has
increased.
f:
Pull the windshield wiper lever
toward you to spray windshield
washer fluid and activate the wipers.
The wipers will continue until the
lever is released or the maximum
wash time is reached. When the
windshield wiper lever is released,
additional wipes may occur depending
on how long the windshield washer
had been activated. See Washer Fluid
0 343 for information on filling the
windshield washer fluid reservoir.
Compass
The vehicle has 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/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

require service. The light should come
on to show that it is working when
the ignition is in Service Mode. See
Ignition Positions0232.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when it
comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not run
smoothly. This could lead to costly
repairs that might not be covered
by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not meet
the original tire specifications, can
cause this light to come on. This
could lead to costly repairs not
covered by the vehicle warranty.
This could also affect the vehicle’s
ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications 0323.
If the light is f lashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service may
be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
If towing a trailer, reduce the amount
of cargo being hauled as soon as
possible. If the light continues to flash, find a
safe place to park. Turn the vehicle off
and wait at least 10 seconds before
restarting the engine. If the light is
still flashing, follow the previous
guidelines and see your dealer for
service as soon as possible.
If the light is on steady :
A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
.If fuel has been added to the vehicle
using the capless fuel funnel
adapter, make sure that it has been
removed. See “Filling the Tank with
a Portable Gas Can ”under Filling the
Tank 0312. The diagnostic system
can detect if the adapter has been
left installed in the vehicle, allowing
fuel to evaporate into the
atmosphere. A few driving trips with
the adapter removed may turn off
the light.
.Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed up.
If this occurs, change the fuel

full tank of the proper fuel to turn
the light off. SeeRecommended Fuel

Recommended Fuel (L3B 2.7L L4
Turbo and LF4 3.6L V6 Twin Turbo
Engines) 0311.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the vehicle may affect vehicle operation.
See
Add-On Electrical Equipment 0321.
See your dealer if assistance is needed.
The vehicle may not pass
inspection if:
.The light is on when the engine is
running.
.The light does not come on when
the ignition is in Service Mode.
.Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if the
12-volt battery has recently been
replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not
pass or cannot be made ready for
the test.

If the HUD image is too bright or
too high in your field of view, it
may take you more time to see
things you need to see when it is
dark outside. Be sure to keep the
HUD image dim and placed low in

If equipped with HUD, some
information concerning the operation
of the vehicle is projected onto the
windshield. The information is
projected through the HUD lens on
the driver side of the instrument
panel and focused out toward the
front of the vehicle.
Caution
If you try to use the HUD image as
a parking aid, you may misjudge
the distance and damage your
vehicle. Do not use the HUD image
as a parking aid. The HUD information can be
displayed in various languages. The
speedometer reading and other
numerical values can be displayed in
either English or metric units.
The language selection is changed
