Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
116 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

To Activate
1. Enable the Automatic High Beams. Refer to “Elec-tronic Vehicle Information Center (EVIC)/Customer-
Programmable Features” in “Understanding Your In-
strument Panel” for further information.
2. Turn the headlight switch to the AUTO headlight position.
3. Push the multifunction lever away from you (toward front of vehicle) to engage the high beam mode.
NOTE: This system will not activate until the vehicle is
at or above 20 mph (32 km/h).
To Deactivate
1. Pull the multifunction lever toward you (or rearward in car) to manually deactivate the system (normal
operation of low beams). 2. Push back on the multifunction lever once again to
reactivate the system.
Daytime Running Lights — If Equipped
The Daytime Running Lights (low intensity) come on
whenever the engine is running, and the transmission is
not in the PARK position. The lights will remain on until
the ignition is switched to the OFF or ACC position or the
parking brake is engaged. The headlight switch must be
used for normal nighttime driving.
NOTE: The Daytime Running Lights will turn off auto-
matically when a turn signal is in operation and turn on
again when the turn signal is not operating.

NOTE:
•When you use the SET -button to decelerate, if the
engine’s braking power does not slow the vehicle
sufficiently to reach the set speed, the brake system
will automatically slow the vehicle.
• The ACC system can only apply a maximum of 25% of
the vehicle’s braking capability and will not bring the
vehicle to a complete stop.
• The ACC system maintains set speed when driving up
hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting
may occur while climbing uphill or descending down-
hill. This is normal operation and necessary to main-
tain set speed.Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between 3 (long), 2 (me-
dium), and 1 (short). Using this distance setting and the
vehicle speed, ACC calculates and sets the distance to the
vehicle ahead. This distance setting displays in the EVIC.
Distance Setting 3

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 235

If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in the
same lane, the EVIC displays the “Sensed Vehicle Indi-
cator” icon, and the system adjusts vehicle speed auto-
matically to maintain the distance setting, regardless of
the set speed.
The vehicle will then maintain the set distance until:
•The vehicle ahead accelerates to a speed above the set
speed.
• The vehicle ahead moves out of your lane or view of
the sensor.
• The vehicle ahead slows to a speed below 15 mph
(24 km/h) and the system automatically disengages
itself. •
The distance setting is changed.
• The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE: The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to
maintain the set distance. If this occurs, a visual alert
“BRAKE” will flash in the EVIC and a chime will sound
while ACC continues to apply its maximum braking
capacity. When this occurs, you should immediately
apply the brakes as needed to maintain a safe distance
from the vehicle ahead.

14. Brake Warning LightThis light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop. The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.

WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer. The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.
15. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
322 UNDERSTANDING YOUR INSTRUMENT PANEL

brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.
16. Speedometer
Indicates vehicle speed.
17. Sport ModeThis light will illuminate when the sport mode
or track mode is selected. These modes provide
performance based tuning with improved han-
dling and acceleration through an electronic
controlled dampening system. This system reduces body
roll and pitch in many driving situations including
cornering, acceleration and braking.
18. Fuel Door Reminder
The fuel pump symbol points to the side of the
vehicle where the fuel door is located. 19. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON/RUN position.
20. Electronic Vehicle Information Center (EVIC) White
Telltale Area
This area will display the EVIC reconfigurable white
telltales. For further information, refer to “Electronic
vehicle Information Center (EVIC)”.
21. Electronic Vehicle Information Center (EVIC) Amber
Telltale Area
This area will display the EVIC reconfigurable amber
caution telltales. For further information, refer to “Elec-
tronic vehicle Information Center (EVIC)”.

The main display area will normally display the main
menu or the screens of a selected feature of the main
menu. The main display area also displays “pop up”
messages that consist of approximately 60 possible warn-
ing or information messages. These pop up messages fall
into several categories:
•Five Second Stored Messages
When the appropriate conditions occur, this type of
message takes control of the main display area for five
seconds and then returns to the previous screen. Most of
the messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the “Messages” main menu item. As long
as there is a stored message, an “i” will be displayed in
the EVIC’s compass/outside temp line. Examples of this
message type are”Right Front Turn Signal Lamp Out”
and “Low Tire Pressure”. •
Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples
of this message type are “Turn Signal On” (if a turn signal
is left on) and “Lights On” (if driver leaves the vehicle).
• Unstored Messages Until RUN
These messages deal primarily with the Remote Start
feature. This message type is displayed until the ignition
is in the RUN state. Examples of this message type are
“Remote Start Aborted - Door Ajar” and “Press Brake
Pedal and Push Button to Start”.
• Five Second Unstored
When the appropriate conditions occur, this type of mes-
sage takes control of the main display area for five seconds
and then returns to the previous screen. Examples of this
message type are “Memory System Unavailable - Not in
Park” and “Automatic High Beams On”.
