When the ignition is on, the fuel gauge
indicates about how much fuel is 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 will take a little more,
or less than half the tank's capacity to fill
the tank.
.Moves 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.
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 0255 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. See Dual Clutch
Transmission 0195 for more information.

Malfunction Indicator Lamp
(Check Engine Light)
This light is part of the vehicle’s emission
control on-board diagnostic system. If this
light is on while the engine is running, a
malfunction has been detected and the
vehicle may require service. The light should
come on to show that it is working when
the ignition is in Service Mode. SeeIgnition
Positions 0190.
Malfunctions are often indicated by the
system before any problem is noticeable.
Being aware of the light and seeking service
promptly when it comes on may prevent
damage.
Caution
If the vehicle is driven continually with
this light on, the emission control system
may not work as well, the fuel economy
may be lower, and the vehicle may not
run smoothly. This could lead to costly
repairs that might not be covered by the
vehicle warranty.
Caution
Modifications to the engine, transmission,
exhaust, intake, or fuel system, or the
use of replacement tires that do not
meet the original tire specifications, can
cause this light to come on. This could
lead to costly repairs not covered by the
vehicle warranty. This could also affect
the vehicle’s ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications 0232.
If the light is flashing : A malfunction has
been detected that could damage the
emission control system and increase vehicle
emissions. Diagnosis and service may be
required. To help prevent damage, reduce vehicle
speed and avoid hard accelerations and

.If fuel has been added to the vehicle
using the capless funnel adapter, make
sure that it has been removed. See
“Filling the Tank with a Portable Gas Can”
under Filling the Tank 0228. The
diagnostic system can detect if the
adapter has been left installed in the
vehicle, allowing fuel to evaporate into
the atmosphere. A few driving trips with
the adapter removed may turn off the
light.
.Poor fuel quality can cause inefficient
engine operation and poor driveability,
which may go away once the engine is
warmed up. If this occurs, change the fuel
