Speed Dependent Volume (SDV)
With SDV, your audio system adjusts automatically to
make up for road or wind noise as you drive.
This feature will never completely compensate for
driving noise. There are other factors such as road
surface, wind noise, windows open, and engine speed
that may alter the interior noise for any given road
speed.
You can select compensation rates between 0 (off) and
5 (maximum compensation) in the options menu.
See “Options Menu Adjustment” later in this section to
adjust SDV.
Dynamic Distortion Limiting (DDL)
Your radio has a feature that limits the amount of
amplifier distortion that you can hear. When this feature
is turned on, it continuously monitors the quality of
the signal to the speakers. When the signal distortion
exceeds the preset limits the radio will automatically limit
or reduce the volume until the distortion is minimized.
Under some circumstances, distortion may be heard for
a very short period of time until the system has taken
the necessary steps to limit it.
The main source of distortion in music is the low
frequency bass caused by drums or large instruments.
Music that features very strong bass may trigger the
distortion limiting system and the system will then
reduce the volume to minimize the distortion.Increasing the bass control or the EQ boost may also
result in a reduced volume level due to the emphasized
bass. See “Setting the Tone (Bass/Treble)” previously
in this section. The DDL can be turned off so that
the radio will deliver a higher volume level, but distortion
will also be increased.
See “Options Menu Adjustment” later in this section to
adjust DDL.
Options Menu Adjustment
Confirmation beeps, SDV, and DDL can all be adjusted
by doing the following:
1. Turn off the radio by pressing the OFF button.
2. Press the ON button and pushbutton 1 at the same
time until Options Menu appears on the display.
3. Push the AUDIO knob until the correct option
appears on the display.
4. Turn the AUDIO knob to adjust the setting of the
option being displayed.
5. Push the AUDIO knob to select another option or
press the OFF button to exit the options menu.
Your selection will be saved.
If no buttons are pressed or turned for eight
seconds, the radio will automatically exit the menu
and the radio will turn on.

Master Reset
Your radio has a reset feature that allows you to return
certain settings back to the factory default settings.
Use this feature when adjustments have been made that
affect the sound quality or operation of the radio and
you are unsure of how to return to the original settings.
This master reset feature will reset the following:
•Bass, Treble, Fade, and Balance
•Confirmation beeps to on
•SDV to setting 2
•DDL to on
•EQ to off.
To perform the master reset, do the following:
1. Turn off the radio by pressing the OFF button.
2. Press the ON button and pushbutton 4 at the same
time for about two seconds.
After the radio has finished resetting, the radio will
turn on with the original settings and no message
will appear on the display.
Mobile Telephone
Your radio includes a telephone adapter. The phone
adapter and the radio are connected. If a mobile phone
hands-free kit with the correct features, such as mute
line and wiring for a separate speaker has been
connected to it, the sound of the radio or CD will be
muted when the phone rings, the voice of the caller will
then be heard through the vehicle’s speakers, and
VOICE ON will appear on the display. When the call
ends, the radio or CD will come back on.
If the radio is off, it will turn on for a phone call if the
vehicle’s ignition is in ON or ACCESSORY.
If a call is in progress when the vehicle is turned off, the
radio will remain on until the call is completed.
You can adjust the volume, bass, treble, fade, and
balance when a phone call is in progress without
affecting the radio settings.

Theft-Deterrent Feature
Your radio has an electronically coded security system.
The system recognizes the vehicle which your radio
has been installed. If the radio is kept in the vehicle, the
PIN should not be required, even if the battery or the
radio has been removed and reinstalled.
If the link between your vehicle and the radio is
disrupted, the radio will prompt you for a 4-digit PIN
code to be entered.
The PIN is supplied on your security card. As the pin is
the only means of enabling operation of the radio,
place the security card in a safe place. Do not leave the
security card in your glovebox. The PIN should also
be written down and kept with other important
documents.
If your security card is lost and the PIN is not recorded,
the PIN can be requested from your dealer, after
supplying proof of ownership. There may be a charge
for this service.
When the radio and vehicle are turned off, the blinking
red light indicates that your radio is armed.
Security Release Procedure
To type in your PIN code, do the following:
1. Turn the ignition to ACCESSORY.
2. Turn the radio on. CODE____will appear on the
display.
3. Use the preset buttons to enter the PIN code.
If the wrong PIN code is entered, the radio will display
CODE ERR WAIT.
After a few seconds, the radio will display
CODE 2____,indicating that this is the second
attempt. The correct code should now be entered.
After three attempts, the radio will display
LOCK OUT 1 HR. After 1 hour, the radio will allow
another three attempts to enter the PIN.

Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down firmly and let anti-lock work for you. You may hear
the anti-lock pump or motor operate, and feel the
brake pedal pulsate, but this is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Traction Control System (TCS)
Your vehicle has a Traction Control System (TCS) 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 rear wheels are spinning or
beginning to lose traction. When this happens,
the system reduces engine power and applies the
brakes, as necessary.
Traction control helps you to keep control of the vehicle
and reminds you to match your speed to the road
conditions. In addition, traction control when activated,
provides feedback to the driver by pulsing the
accelerator pedal.You may feel or hear the system working, but this is
normal. The TCS is automatically turned on whenever
the ignition is turned from off to on. A Low Traction
message is displayed on the trip computer, indicating
traction control is limiting wheel spin, until the MODE
button on the trip computer is pressed. The message
then goes back to the original trip computer display with
a small low traction symbol on the left. The symbol
will remain as long as the low traction situation exists.
To limit wheel spin, especially in slippery road
conditions, you should always leave the TCS on.
But you can turn the system off if you prefer.
To turn the system off,
press the T/C button.
On manual transmission
vehicles the button is
located on the driver’s side
of the center console.
On automatic transmission
vehicles the button is
located on the passenger’s
side of the shift lever.
4-8

When you turn the system off, a Traction Ctrl Off
message is displayed on the trip computer. After
two seconds, the display goes back to the original
trip computer display with a small TRAC OFF icon
on the right.
If the Traction Ctrl Off message does not display when
the button is pressed, or if it comes on during driving,
a problem is indicated in the system and traction control
is no longer operational. You should contact your
dealer for service.
Pressing the T/C button again or the next time the
ignition is turned on, will turn the system back on.
The Traction Ctrl On message is displayed on the trip
computer. After two seconds, the display goes back
to the original trip computer display.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Steering Tips
Driving on Curves
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle at
which the curve is banked, and your speed. While
you are in a curve, speed is the one factor you
can control.
Suppose you are steering through a sharp curve.
Then you suddenly apply the brakes. Both control
systems — steering and braking — have to do their
work where the tires meet the road. Unless you
have four-wheel anti-lock brakes, adding the hard
braking can demand too much of those places.
You can lose control.

If the Check Oil message appears on the trip computer
display, it means you need to check your engine oil
level right away.
For more information, seeOil Pressure Light on
page 3-32.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don’t, the oil
dipstick might not show the actual level.
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
5-13

Checking Coolant
The coolant surge tank is located in the engine
compartment on the driver’s side of the vehicle. See
Engine Compartment Overview on page 5-12for more
information on location.
{CAUTION:
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. Never turn the surge tank pressure
cap — even a little — when the engine and
radiator are hot.
The coolant level should be checked at least weekly, by
looking at the level on the coolant reservoir when the
engine is cold. The vehicle must be on a level surface.
When your engine is cold, the coolant level should
be at or slightly above the COLD FILL mark, at
the center weld joint. The level rises when the engine is
running and drops when the engine cools down. If
the level falls below the weld joint, the coolant should
be added to a little over the mark. Do not overfill,
as coolant requires space to expand when warmed up.
If the Low Coolant message on the trip computer
display comes on and stays on, it means you’re low on
engine coolant. You should check the level as soon
as possible. You may have to check the coolant level
when it is hot. SeeEngine Overheating on page 5-28.
5-27

Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixtureat the surge tank, but only when the
engine is cool.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
When the level is correct, replace the cap and turn
clockwise until secure.
Engine Overheating
Immediate action is required if your engine overheats.
This is indicated by the coolant temperature gage
and the Engine Temp Hot message on the trip computer
display.Engine Coolant Temperature Gage on
page 3-28.
