{Warning
If temperature change or
pain to the skin cannot be
felt, the seat heater may
cause burns. To reduce the
risk of burns, use care when
using the seat heater,
especially for long periods of
time. Do not place anything
on the seat that insulates
against heat, such as a (Continued)

blanket, cushion, cover,
or similar item. This may
cause the seat heater to
overheat. An overheated
seat heater may cause a
burn or may damage
the seat.
If equipped, the buttons are
near the climate controls on
the center stack. To operate,
the engine must be running.

automatically be lowered after
approximately 30 minutes.
When this feature is off, the

symbols on the buttons are
white. A ventilated seat has a
fan that pulls air through the
seat. The air is not cooled.
When a heated seat is turned
on, the symbol turns red.
When a ventilated seat is
turned on, the symbol
turns blue. The passenger seat may take
longer to heat up.

Seats
If the vehicle is equipped with
auto heated or ventilated
seats, and the engine is
running, this feature will
automatically activate the
heated or ventilated seats at
the level required by the
vehicle's interior temperature.
The active high, medium, low,
or off heated or ventilated
seat level will be indicated by
the manual heated and
ventilated seat buttons on the
center stack. Use the manual
heated and ventilated seat
buttons on the center stack to
turn auto heated or ventilated
seats off. If the passenger
seat is unoccupied, the auto
heated or ventilated seats
feature will not activate that
seat. If equipped with a heated
steering wheel, the auto

window or a door. If you
experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that
may automatically unlock the
doors, turn on the interior
lamps and hazard warning
flashers, and shut off the fuel
system after the airbags
inflate. The feature may also
activate, without airbag
inflation, after an event that
exceeds a predetermined
threshold. After turning the
ignition off and then on again,
the fuel system will return to
normal operation; the doors
can be locked, the interior
lamps can be turned off, and
the hazard warning flashers
can be turned off using the
controls for those features.
If any of these systems are
damaged in the crash they
may not operate as normal.
{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
0496 and
Event Data Recorders 0497.
.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.

Gauges, and

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 (Electronic
Shifter)
0281 or
Manual Mode (Mechanical
Shifter) 0280. 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

information.
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.
