The HUD information can be displayed in one of three
languages, English, French, or Spanish. The
speedometer reading and other numerical values can
be displayed in either English or metric units.
The language selection and the units of measurement
are changed through the trip computer in the Driver
Information Center (DIC). See “Options” under
DIC Controls and Displays (Base Level DIC) on
page 3-49orDIC Controls and Displays (Uplevel DIC
with Trip Computer) on page 3-57.
The HUD information appears as an image focused out
toward the front of the vehicle.When the ignition key is turned to run, the HUD will
display an introductory message for a short time, until
the HUD has warmed up.
The following indicator lights come on the instrument
panel when activated and will also appear on the HUD:
Turn Signal Indicators
High-Beam Indicator Symbol
The HUD will temporarily display CHECK TRIP
COMPUTER when there are messages on the DIC trip
computer.
The HUD will also display the following messages when
these systems, if equipped, are active:
TRACTION CONTROL ACTIVE
STABILITY CONTROL ACTIVE
The HUD will temporarily display the TRACTION
CONTROL OFF message when the traction control
system is turned off.
The HUD will temporarily display the CRUISE SET
message when cruise control is activated or cruise
speed is increased.
Notice:If you try to use the HUD image as a parking
aid, you may misjudge the distance and damage your

Cruise Control Light
This light, if equipped,
comes on whenever you
set your cruise control.
The light will go out when the cruise control is turned off.
SeeCruise Control on page 3-10for more information.
Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
See “Headlamp High/Low-Beam Changer” under
Exterior Lamps on page 3-14for additional information.
Fuel Gage
The fuel gage shows
about how much fuel
is left in the fuel tank
when the ignition is on.
When the indicator nears empty, there is still a little fuel
left, but you should get more soon.
Here are four things owners usually ask about the fuel
gage. All these situations are normal and do not
indicate a problem with the fuel gage:
At the gas station the pump shuts off before the
gage reads full.
It takes more or less fuel to ll up than the gage
indicates. For example, the gage reads half full, but it
took more or less than half the tank’s capacity to ll it.
The gage pointer may move while cornering, braking
or speeding up.
The gage may not indicate full when the ignition is
turned off.

This message will display while the ignition is in RUN.
A chime will sound for two seconds when this message
is displayed. Press the set/reset button to acknowledge
this message and to clear it from the screen.
This message will continue to display for three seconds
if it has not been acknowledged when the engine is
turned off. It will also re-display for three seconds if the
message has been acknowledged, but the condition
still exists when the engine is turned off.
If the condition still exists, the message will re-appear
when the engine is turned on.
CRUISE SET
This symbol comes on
with the CRUISE SET
message.This message and symbol come on briey whenever
the cruise control is set. The cruise control light on
the instrument panel cluster will also come on when
cruise control is set. SeeCruise Control Light on

Press the traction
control button located
on the console to turn
the system off.
If the system is limiting wheel spin when the traction
control button is pressed, the system will turn off
instantly. Turn the system back on at any time by
pressing the button again.
If the vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow safe use of it, the cruise control can be
used again. SeeCruise Control on page 3-10.Enhanced Traction System (ETS)
If the vehicle has the 3800 V6 engine and anti-lock
brakes, it may have an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if
it senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may
also upshift the transaxle to limit wheel spin.
This symbol comes on
the Driver Information
Center (DIC) when
the ETS is limiting
wheel spin.
If the vehicle is in cruise control when ETS begins to
limit wheel spin, the cruise control will automatically
disengage. When road conditions allow safe use of it,
the cruise control can be used again. SeeCruise Control
on page 3-10.

StabiliTrak®Plus System
The vehicle may have a vehicle stability enhancement
system called StabiliTrak®Plus. It is an advanced
computer controlled system that assists with directional
control of the vehicle in difficult driving conditions.
StabiliTrak
®Plus comes on whenever the vehicle is
started. It activates when the computer senses a
discrepancy between the intended path and the direction
the vehicle is actually traveling. StabiliTrak
®Plus
selectively applies braking pressure at any one of the
vehicle’s brakes to help control the vehicle in the
steering direction.
This symbol, along with
the STABILITY CONTROL
ACTIVE message comes
on the Driver Information
Center (DIC).
SeeDIC Warnings and Messages on page 3-69. You
may also hear a noise or feel vibration in the brake
pedal. This is normal. Continue to steer the vehicle in
the desired direction.If there is a problem
detected with StabiliTrak
®
Plus, this symbol along
with the SERVICE
STABILITY SYSTEM
warning message
will come on the DIC.
SeeDIC Warnings and Messages on page 3-69. When
this message is displayed, the system is not operational.
Driving should be adjusted accordingly.
To turn the StabiliTrak
®system off, press and hold
the traction control button for more than ve seconds.
A message will appear on the DIC indicating that
StabiliTrak
®has been turned off. You can turn the system
back on at any time by pressing the button again.
If the vehicle is in cruise control when StabiliTrak
®Plus
activates, the cruise control will automatically disengage.
When road conditions allow safe use of it, the cruise
control can be used again. SeeCruise Control on
page 3-10for more information.

(e)Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced. Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
(The airbag system does not need regular maintenance.)
(f)Lubricate all key lock cylinders. Lubricate all hinges
and latches, including those for the body doors,
hood, secondary latch, pivots, spring anchor, release
pawl, rear compartment, glove box door, console
door and any folding seat hardware. More frequent
lubrication may be required when exposed to a corrosive
environment. Applying silicone grease on weatherstrips
with a clean cloth will make them last longer, seal
better and not stick or squeak.
(g)If you drive regularly under dusty conditions, the
lter may require replacement more often.
(h)Change automatic transaxle uid and lter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.When doing frequent trailer towing.
Uses such as found in taxi, police or delivery
service.
(i)Drain, ush and rell cooling system. See Engine
Coolant on page 5-24for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap and ller neck.
Pressure test the cooling system and pressure cap.
(j)Check throttle system for interference or binding and
for damaged or missing parts. Replace parts as
needed. Replace any components that have high effort
or excessive wear. Do not lubricate accelerator or
cruise control cables.
(k)A uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired
and the uid level checked. Add uid if needed.
(l)For supercharged engines only: Check the
supercharger oil level and add the proper supercharger
oil as needed (or every 36 months, whichever occurs
rst). See Recommended Fluids and Lubricants on
page 6-12.
(m)If you drive regularly under dusty conditions, inspect
the lter at each engine oil change.
