32 Keys, Doors, and Windows
The security light, in the
instrument cluster, comes on if
there is a problem with arming
or disarming the
theft-deterrent system.
The system has one or more
remote keys matched to an
immobilizer control unit in the
vehicle. Only a correctly
matched remote key will start
the vehicle. If the remote key
is ever damaged, you may not
be able to start your vehicle.
When trying to start the
vehicle, the security light may
come on briefly.
If the engine does not start
and the security light stays on,
there is a problem with the
system. Turn the ignition off
and try again.If the vehicle will not change
ignition modes (accessory
mode, on, off), and the remote
key appears to be undamaged,
try another remote key. Or,
you may try placing the
remote key in the backup
location. See Remote Key
Operation
09.
If the ignition modes will not
change with the other remote
key or in the backup location,
the vehicle needs service.
If the ignition does change
modes, the first remote key
may be faulty. See your dealer.
It is possible for the
immobilizer system to learn
new or replacement remote
keys. Up to eight remote keys
can be programmed for the
vehicle. To program additional
remote keys, see
“Programming Remote Keys to
the Vehicle” under Remote
Key Operation 09. Do not leave the remote key
or device that disarms or
deactivates the
theft-deterrent system in the
vehicle.Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make
things, like other vehicles,
look farther away than they
really are. If you cut too
sharply into the right lane,
you could hit a vehicle on
the right. Check the inside
mirror or glance over your
shoulder before changing
lanes.
The passenger side mirror is
convex shaped. A convex
mirror's surface is curved so
more can be seen from the
driver seat.

72 Seats and Restraints
{Warning
A crash severe enough to
inflate the airbags may have
also damaged important
functions in the vehicle, such
as the fuel system, brake
and steering systems, etc.
Even if the vehicle appears
to be drivable after a
moderate crash, there may
be concealed damage that
could make it difficult to
safely operate the vehicle.
Use caution if you should
attempt to restart the
engine after a crash has
occurred.
In many crashes severe
enough to inflate the airbag,
windshields are broken by
vehicle deformation. Additional
windshield breakage may also
occur from the front outboard
passenger airbag.
.Airbags are designed to
inflate only once. After an
airbag inflates, you will need
some new parts for the
airbag system. If you do not
get them, the airbag system
will not be there to help
protect you in another crash.
A new system will include
airbag modules and possibly
other parts. The service
manual for the vehicle
covers the need to replace
other parts.
.The vehicle has a crash
sensing and diagnostic
module which records
information after a crash.
See Vehicle Data Recording
and Privacy 0498 and
Event Data Recorders 0499.
.Let only qualified technicians
work on the airbag system.
Improper service can mean
that an airbag system will
not work properly. See your
dealer for service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position.
The passenger airbag status
indicator will light on the
overhead console when the
vehicle is started.
The words ON and OFF, and
the symbols for on and off, will
be visible during the system
check. When the system check
is complete, either the word
ON or OFF, and the symbol for
on or off, will be visible. See
Passenger Airbag Status
Indicator 0124.
The passenger sensing
system turns off the front
outboard passenger frontal
airbag and knee airbag under

Warning lights and gauges can
signal that something is wrong
before it becomes serious
enough to cause an expensive
repair or replacement. Paying
attention to the warning lights
and gauges could prevent
injury.
Some warning lights come on
briefly when the engine is
started to indicate they are
working. When one of the
warning lights comes on and
stays on while driving, or when
one of the gauges shows
there may be a problem, check
the section that explains what
to do. Waiting to do repairs
can be costly and even
dangerous.

Tachometer
The tachometer displays the
engine speed in revolutions
per minute (rpm).
For vehicles with the Stop/
Start system, when the
ignition is on, the tachometer
indicates the vehicle status.
When pointing to AUTO STOP
(Base Level) or the cluster
displays AUTO STOP text
(Uplevel), the engine is off but
the vehicle is on and can move.
The engine could auto start at
any time. When the indicator
points to OFF, the vehicle
is off.
The tachometer may vary by
several hundred rpm, during
Auto Stop mode, when the
engine is shutting off and
restarting.
Uplevel
The redline of the tachometer
adjusts dynamically based on
engine temperature. The
redline displays a lowerindication when the vehicles
odometer value is less than
805 kilometers (500 miles).
If equipped, the shift
indicators are displayed on
instrument cluster and
Head-Up Display (HUD). The
shift indicators are only
operational when the
automatic transmission is in
Manual mode, or the vehicle
has a manual transmission.
See Manual Mode
0282. When
the vehicle engine is less than
70°C (158°F) and the vehicle
odometer value is less than
805 kilometers (500 miles) the
shift indications are not
displayed.
A strong visual indicator is
displayed as the vehicle
approaches the red line. Tour
and Sport themes feature
shift rings while the Track
theme features shift lights
accompanied by a numerical
tachometer display.

When the ignition is on, the
fuel gauge indicates the
approximate amount of fuel
left in the tank.
There is an arrow near the
fuel gauge pointing to the side
of the vehicle the fuel door
is on.
When the indicator nears
empty, the low fuel light
comes on. There still is a little
fuel left, but the vehicle should
be refueled soon.
The fuel gauge may:
.Take a little more, or less
fuel to fill up than it
indicates. For example, the
gauge may have indicated
the tank is half full, but it actually takes a little more,
or less than half the tank's
capacity to fill the tank.
.Move a little while turning a
corner, speeding up,
or braking.
.Take a few seconds to
stabilize after the ignition is
turned on and goes back to
empty when the ignition is
turned off.
These are normal conditions,
none of which indicate a
problem with the fuel gauge.
Fuel Range
The uplevel instrument cluster
has a estimated fuel range
located at the bottom center
of the display. The fuel range
is displayed with the
approximate distance the
vehicle can be driven without
refueling. The fuel range
estimate is based on an
average of the vehicle’s fuel
economy over recent driving
history and the amount of fuel
remaining in the fuel tank. When the estimated fuel
range is low, the range shows
LOW and a message may also
display in the Driver
Information Center (DIC).

This gauge measures the
temperature of the vehicle's
engine.
While driving under normal
operating conditions, if the red
LED is illuminated, the engine
is too hot. Pull off the road,
stop the vehicle, and turn off
the engine as soon as
possible.

This gauge shows the engine
coolant temperature.
If the gauge pointer moves
into the red zone, the engine is
too hot.
This reading indicates the
same thing as the warning
light. It means that the engine
coolant has overheated. If the
vehicle has been operating
under normal driving
conditions, pull off the road,
stop the vehicle, and turn off
the engine as soon as possible. See Engine

Seat Belt Reminders
Driver Seat Belt Reminder
Light
There is a driver seat belt
reminder light on the
instrument cluster.
When the vehicle is started,
this light flashes and a chime
may come on to remind the
driver to fasten their seat belt.
Then the light stays on solid
until the belt is buckled. This
cycle may continue several
times if the driver remains or
becomes unbuckled while the
vehicle is moving.
