Vehicle Damage Warnings
Also, in this book you will find these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
You’ll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a specific component, control,
message, gage or indicator.
If you need help figuring out a specific name of a
component, gage or indicator, reference the following
topics:
•Seats and Restraint Systems in Section 1
•Features and Controls in Section 2
•Instrument Panel Overview in Section 3
•Climate Controls in Section 3
•Warning Lights, Gages and Indicators in Section 3
•Audio System(s) in Section 3
•Engine Compartment Overview in Section 5

Ignition Positions
With the key in the ignition switch, you can turn it to
three different positions.
A (LOCK and ACCESSORY):This is the only position
from which you can insert or remove the key. When
the key is inserted and is in this position, all accessories,
electrical systems, and engine are off. If the key is
cycled back to this position the accessories will remain
on until the key is removed. Once the key is removed
the accessories will turn off. If the key is left inserted in
this position, a chime will sound when the driver’sdoor is opened to remind you the key has been left in
the ignition. The key can only be turned to this position if
the vehicle’s automatic transmission is in PARK (P).
To help guard against theft, your vehicle’s engine
is automatically disabled shortly after turning the key to
this position. This is indicated by the flashing padlock
symbol on the bottom left corner of the instrument panel.
The steering column is automatically locked when the
key is removed. To release the steering wheel, insert the
key again and turn it towards the front of the vehicle.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in. If
it is, turn the steering wheel left and right while you
turn the key hard. If none of this works, then
your vehicle needs service.
B (ON and ACCESSORY):This position is where the
key returns to after you start your engine and release the
key. The ignition switch stays in ON when the engine
is running. But even when the engine is not running, you
can use ON to operate your electrical accessories
and to display some instrument panel warning lights.
C (START):This position starts the engine. When
the engine starts, release the key. The ignition switch
will return to ON for normal driving.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly – and even dangerous. So please get to know
your warning lights and gages. They’re a big help.
Your vehicle also has a trip computer that works along
with the warning lights and gages. The trip computer
display provides visual information. SeeTrip Computer
on page 3-36. The warning message are displayed
through the trip computer or as an illuminated symbol or
sometimes both ways.
If a Service Error Contact Dealer message appears on
the trip computer display while driving, a fault in the
instrument panel is indicated. Contact your dealer
as soon as possible. This message will remain until the
MODE button on the trip computer is pressed.
3-23

Trip A/B
When the Time to Arrival/Distance to Arrival/Fuel
Remaining set of windows are turned on, using vehicle
personalization, and are showing on the display,
hold the MODE button down for two seconds. Now,
instead of the Time to Arrival set of displays, the
trip computer shows Trip B details.
Press the MODE button to view your displays. You now
have two different sets of trip displays counting, your
original set of trip displays (labeled A while B is turned
on) and a new set of trip displays, labelled B. This is
useful on a long trip, as Trip B can be reset at the
beginning of the journey and then locked away
(by pressing the MODE button for two seconds when
Trip B is shown). Time to Arrival/Distance to
Arrival/Remaining Fuel will again be shown on the
display, but Trip B is still counting away in the
background and the original trip display can be used for
short distances during the journey. Trip B can be
viewed at any time by pressing the MODE button for
two seconds when Distance to Arrival is shown.
Trip A/B can also be enabled/disabled in vehicle
personalization, SeeVehicle Personalization on
page 2-32. If the Trip A and B function is selected,
the Average Speed and Average Fuel displays
indicate Trip A.
Trip Computer Notes:
•If the wrong buttons are accidentally pressed,
causing the window to show a display other
than normal, turn the ignition off then on again
when the vehicle is standing still.
•Several warning lights are linked to the trip
computer displays. SeeWarning Lights, Gages, and
Indicators on page 3-23.
•When the overspeed warning symbol is first shown,
the overspeed trip computer display is automatically
shown for 10 seconds. This is to show what your
pre-selected speed is and allow you to adjust
it if required. After 10 seconds, the trip computer
returns to its previous display.
•Some displays change the units of measurement
over time. For example, the Time to Arrival shows
hours only above 99 hours and 59 minutes,
and hours and minutes below. Time to Arrival also
shows 10 minute units above 2 hours, 5 minute
units below 2 hours and 1 minute units below
10 minutes.
•If the X symbol or a Service Error message is
shown in the display, it indicates a fault in the
trip computer and you should see your vehicle
dealer.

Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add
only DEX-COOL
®extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating on
page 5-28.A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will do the following:
•Give freezing protection down to−34°F (−37°C)
•Give boiling protection up to 265°F (129°C)
•Protect against rust and corrosion
•Help keep the proper engine temperature
•Let the warning lights and gages work as they
should
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
