Vehicle Damage Warnings
Also, in this manual you will ®nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage your
vehicle. Many times, this damage would not be covered
by your vehicle's 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.
There are also warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a speci®c component, control, message,
gage, or indicator.
If you need help ®guring out a speci®c name of a
component, gage, or indicator, reference the
following topics:
·Seats and Restraint Systems in Section 1
·Features and Controls in Section 2

When you move out of PARK (P) or NEUTRAL (N) and
the engine is running, the parking brake should
release. If the parking brake has not been fully released
and you try to drive off with the parking brake on, the
parking brake indicator light will come on and stay on.
If the parking brake does not fully release, you can
manually release the pedal. However, be sure to read
the following paragraphs:
{CAUTION:
Always shift to PARK (P) before pulling the
manual release lever. If your hand or arm is in
the way of the pedal you could be hurt. The
pedal springs back quickly. Keep your hand
and arm away when you use the manual
release lever.
Before releasing the manual parking brake, be sure to
put the vehicle in PARK (P) and turn the ignition off.Reach under the driver's side of the instrument panel
and pull down on the manual release lever, which
is located behind the parking brake pedal. Pull down on
the yellow tab as shown by the arrow in the illustration.
If the parking brake does not release, you should
have your vehicle towed to your dealer for service.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.

Lamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver's door is opened with the ignition off.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
®rst sold in Canada.
The DRL system will make the front turn signal lamps
come on when the following conditions are met:
·It is still daylight and the ignition is on,
·the exterior lamp control is in the off position and
·the transmission is not in PARK (P).
When DRL are on, only the front turn signal lamps will
be on. No other exterior lamps such as the parking
lamps, taillamps, etc. will be on when the DRL are being
used. Your instrument panel will not be lit up either.
When it is dark enough outside, the front turn signal
lamps will turn off and normal low-beam headlamps will
turn on.When it is bright enough outside, the regular lamps will
go off, and the front turn signal lamps will take over.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
knob is in the full bright position. See ªInstrument Panel
Brightnessº under
Interior Lamps on page 3-25.
If it is dark enough outside and the exterior lamp control
is off, a HEADLAMPS SUGGESTED message will
display on the Driver's Information Center (DIC). This
message informs the driver that turning on the exterior
lamps is recommended.
Turning the exterior lamp control to off a second time,
or turning on the headlamps will remove the
HEADLAMPS SUGGESTED message. If the parking
lamps or the fog lamps were turned on instead,
the HEADLAMPS SUGGESTED message will continue
to be displayed.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
3-23

Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your ®eld 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 your ®eld of view.
The Head-Up Display (HUD) allows you to see some of
the driver information that appears on your instrument
panel cluster.
The information may be displayed in English or metric
units and appears as an image focused out toward
the front of your vehicle. To change from English
to metric units, see
Driver Information Center (DIC) on
page 3-55.
The HUD consists of the following information:
·Speedometer
·Turn Signal Indicators
·High-Beam Indicator Symbol
·Tap-Up/Tap-Down Transmission Feature
·Check Gages Icon
·Adaptive Cruise Control Features and Indicators
·Radio Features
Be sure to continue scanning your displays, controls
and driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel cluster, you may not see something important,
such as a warning light. Under important warning
conditions, the CHECK GAGES message will display in
the HUD. View your Driver Information Center (DIC)
for more information.

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 brie¯y when you start the
engine just to let you know they are 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 is 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 Ð and even dangerous. So please get to know
your warning lights and gages. They are a big help.
Your vehicle may also have a Driver Information Center
that works along with the warning lights and gages.
See
Driver Information Center (DIC) on page 3-55.
