Caution
If the engine is operated with the rpm in
the warning area at the high end of the
tachometer, the vehicle could be
damaged, and the damage would not be
covered by the vehicle warranty. Do not
operate the engine with the rpm in the
warning area.
Fuel Gauge
When the ignition is on, the fuel gauge
indicates about how much fuel is left in
the tank.
When the indicator nears empty, the low
fuel light comes on. There is still a little fuel
left, but the fuel tank should be filled soon.Here are four things that some owners ask
about. None of these show a problem with
the fuel gauge:
.At the service station, the fuel pump
shuts off before the gauge reads full.
.It takes a little more or less fuel to fill up
than the gauge indicated. For example,
the gauge indicated the tank was half
full, but it actually took a little more or
less than half the tank's capacity to fill
the tank.
.The gauge moves a little while turning a
corner or speeding up.
.The gauge takes a few seconds to
stabilize after the ignition is turned on,
and goes back to empty when the
ignition is turned off.
Engine Coolant Temperature
Gauge
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 Overheating 0248 for
more information.
Transmission Temperature Gauge
This gauge will display when the
transmission is experiencing abnormal
temperatures.
As the transmission begins to overheat, the
gauge fills to the right.
The Transmission Temperature Gauge
monitors all aspects of the transmission.
Elevated transmission temperatures may not
be reflected in the Transmission Fluid
Temperature cluster display gauge.

Messages will display to indicate the
severity of the overheating. As the gauge
fills up there will be a reduction in vehicle
performance. Once full, the transmission is
overheated and a message to stop safely
will display. Do not drive the vehicle until
the message clears. SeeDual Clutch
Transmission 0197 for more 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. If the driver seat belt is buckled, neither the
light nor the chime comes on.
Front Passenger Seat Belt Reminder
Light
The vehicle may have a front passenger seat
belt reminder light near the passenger
airbag status indicator. See
Passenger
Sensing System 057.
When the vehicle is started, this light
flashes and a chime may come on to remind
passengers to fasten their seat belt.
Then the light stays on solid until the belt is
buckled. This cycle continues several times if
the front passenger remains or becomes
unbuckled while the vehicle is moving.
If the front passenger seat belt is buckled,
neither the chime nor the light comes on.
The front passenger seat belt reminder light
and chime may come on if an object is put
on the seat such as a briefcase, handbag,
grocery bag, laptop, or other electronic device. To turn off the reminder light and/or
chime, remove the object from the seat or
buckle the seat belt.
Airbag Readiness Light
This light shows if there is an electrical
problem with the airbag system. The system
check includes the airbag sensor(s), the
passenger sensing system, the pretensioners,
the airbag modules, the wiring, and the
crash sensing and diagnostic module. For
more information on the airbag system, see
Airbag System
052.
The airbag readiness light comes on for
several seconds when the vehicle is started.
If the light does not come on then, have it
fixed immediately.

106 Lighting
This indicator light turns on in the
instrument cluster when the high-beam
headlamps are on.
Flash-to-Pass
To use the flash-to-pass feature, briefly pull
the turn signal lever toward you. The
high-beam indicator flashes to indicate to
the other driver that you intend to pass.
Daytime Running Lamps (DRL)
DRL can make it easier for others to see the
front of your vehicle during the day. DRL are
required on all vehicles first sold in Canada.
The DRL system makes the dedicated lamps
come on when the following conditions
are met:
.The ignition is on.
.The exterior lamp control is in the AUTO.
.The light sensor determines it is daytime.When DRL are on, only the front lamps will
be on. The parking lamps, taillamps,
instrument panel lights, or other exterior
lamps will not be on when the DRL are
being used.
When it is dark enough outside, the front
lamps dim to parking lamps and the normal
low-beam headlamps turn on.
The regular headlamp system should be
turned on when needed.
To turn off the DRL, turn the exterior lamp
control to
O. The DRL will stay off until the
control is toggled again.
Automatic Headlamp System
When the exterior lamp control is set to
AUTO and it is dark enough outside, the
headlamps and parking lamps come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the sensor,
otherwise the headlamps will come on when
they are not needed.
The system may also turn on the headlamps
and parking lamps when driving through a
parking garage or tunnel.
If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. If it is light outside when the
vehicle leaves the garage, there is a slight
delay before the automatic headlamp
system changes to the DRL. During that
delay, the instrument cluster may not be as
bright as usual. Make sure the instrument
panel brightness control is in the full bright
position. See Instrument Panel Illumination
Control 0108.

turned on when needed.
Lights On with Wipers
If the windshield wipers are activated in
daylight with the engine on and the exterior
lamp control is in AUTO, the headlamps,
parking lamps, and other exterior lamps will
come on. The time it takes for the lamps to turn on depends on the wiper speed. When
the wipers are turned off, the lamps turn
