GETTING TO KNOW YOUR INSTRUMENT PANEL107
WARNING LIGHTS AND MESSAGES

The warning/indicator lights will illuminate in the
instrument panel together with a dedicated
message and/or acoustic signal when
applicable. These indications are indicative
and precautionary and as such must not be
considered as exhaustive. Always refer to the
information in this chapter in the event of a
failure indication. All active telltales will display
first if applicable. The system check menu may
appear different based upon equipment options
and current vehicle status. Some telltales are
optional and may not appear.

RED WARNING LIGHTS
Seat Belt Reminder Warning Light

This warning light indicates when
the driver or passenger seat belt is
unbuckled. When the ignition is first
placed in the ON/RUN or ACC/ON/RUN
position and if the driver’s seat belt is unbuckled,
a chime will sound and the light will turn on.
When driving, if the driver or front passenger seat
belt remains unbuckled, the Seat Belt Reminder
Light will flash or remain on continuously and a
chime will sound
Ú
page 292.

Air Bag Warning Light
This warning light will illuminate to
indicate a fault with the air bag, and
will turn on for four to eight seconds
as a bulb check when the ignition
is placed in the ON/RUN or ACC/ON/RUN
position. This light will illuminate with a single
chime when a fault with the air bag has been
detected, it will stay on until the fault is cleared.
If the light is not on during startup, stays on,
or turns on while driving, have the system
inspected at an authorized dealer as soon as
possible.
Brake Warning Light
This warning 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 capacity 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
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is
necessary.

STARTING AND OPERATING
STARTING THE ENGINE — GASOLINE
ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and
fasten your seat belt.
The starter should not be operated for more
than 10-second intervals. Waiting a few
seconds between such intervals will protect the
starter from overheating.
AUTOMATIC TRANSMISSION
Start the engine with the transmission in the
PARK position. Apply the brake before shifting
into any driving range. NOTE:
This vehicle is equipped with a transmission
shift interlocking system. The brake pedal
must be pressed to shift out of PARK.
If equipped with an eight-speed transmis
-
sion, starting the vehicle in NEUTRAL is not
possible unless the Manual Park Release has
been activated. For the Manual Park Release
operation information Ú page 348.
TIP START FEATURE
Do not press the accelerator. Place the ignition
switch briefly to the START position and release
it. The starter motor will continue to run and will
automatically disengage when the engine is
running.
KEYLESS ENTER-N-GO — IGNITION
This feature allows the driver to operate the
ignition switch with the push of a button, as long
as the Remote Start/Keyless Enter-N-Go key
fob is in the passenger compartment.
WARNING!
When leaving the vehicle, always make
sure the keyless ignition node is in the OFF
mode, remove the key fob from the vehicle
and lock the vehicle.

Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil -
dren to be in a vehicle unattended is dangerous
for a number of reasons. A child or others could
be seriously or fatally injured. Children should
be warned not to touch the parking brake,
brake pedal or the gear selector.

Do not leave the key fob in or near the
vehicle, or in a location accessible to chil-
dren, and do not leave the ignition of a
vehicle equipped with Keyless Enter-N-Go
in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or
move the vehicle.
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.

120STARTING AND OPERATING
(Continued)
AUTOPARK — ROTARY SHIFTER AND
E
IGHT SPEED TRANSMISSION ONLY

AutoPark is a supplemental feature to assist in
placing the vehicle in PARK should the situations
on the following pages occur. It is a back up
system and should not be relied upon as the
primary method by which the driver shifts the
vehicle into PARK.

The conditions under which AutoPark will
engage are outlined on the following pages. If the vehicle is not in PARK and the driver turns
off the engine, the vehicle may AutoPark.
AutoPark will engage when all of these
conditions are met:
Vehicle is equipped with a rotary shifter and
an eight speed transmission
Vehicle is not in PARK
Vehicle speed is 1.2 mph (1.9 km/h) or less
Ignition switched from RUN to ACC
NOTE:
For Keyless Enter-N-Go equipped vehicles, the
engine will turn off and the ignition switch will
change to ACC mode. After 30 minutes the igni -
tion switches to OFF automatically, unless the
driver turns the ignition switch OFF. If the vehicle is not in PARK and the driver exits
the vehicle with the engine running, the vehicle
may AutoPark.
AutoPark will engage when all of these
conditions are met:
Vehicle is equipped with a rotary shifter and
an eight speed transmission
Vehicle is not in PARK
Vehicle speed is 1.2 mph (1.9 km/h) or less
Driver’s seat belt is unbuckled
Driver’s door is ajar
Brake pedal is not pressed
The message “ AutoPark Engaged Shift to P then
Shift to Gear ” will display in the instrument
cluster.
NOTE:
In some cases the ParkSense graphic will be
displayed in the instrument cluster, causing the
“ AutoPark Engaged Shift to P then Shift to Gear ”
to not be seen. In these cases, the shifter must
be returned to “P” to select desired gear.
WARNING!

Driver inattention could lead to failure to
place the vehicle in PARK. ALWAYS DO A
VISUAL CHECK that your vehicle is in PARK
by verifying that a solid (not blinking) “P” is
indicated in the instrument cluster display
and near the gear selector. If the "P" indi -
cator is blinking, your vehicle is not in PARK.
As an added precaution, always apply the
parking brake when exiting the vehicle.

AutoPark is a supplemental feature. It is not
designed to replace the need to shift your
vehicle into PARK. It is a back up system
and should not be relied upon as the
primary method by which the driver shifts
the vehicle into PARK.
