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).

If the light stays on, or comes
on while driving, there may be
a problem with the electrical
charging system. Have it
checked by your dealer.
Driving while this light is on
could drain the battery.
When this light comes on, or is
flashing, the Driver Information
Center (DIC) also displays a
message.
If a short distance must be
driven with the light on, be
sure to turn off all
accessories, such as the radio
and air conditioner. Find a safe
place to stop the vehicle.
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 mayrequire service. The light
should come on to show that it
is working when the ignition is
in Service Mode. See Ignition
Positions
0267.
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
(Continued)
Caution (Continued)
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
Modifications0374.
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
uphill grades. If towing a
trailer, reduce the amount of
cargo being hauled as soon as
possible.
If the light continues to flash,
find a safe place to park. Turn
the vehicle off and wait at
least 10 seconds before
restarting the engine. If the
light is still flashing, follow the
previous guidelines and see
your dealer for service as
soon as possible.
If the light is on steady :A
malfunction has been
detected. Diagnosis and
service may be required.
Check the following:
.If fuel has been added to the
vehicle using the capless fuel
funnel adapter, make sure
that it has been removed. See
“Filling the Tank with a
Portable Gas Can” under
Filling the Tank 0362. 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
brand. It may require at least
one full tank of the proper
fuel to turn the light off. See
Recommended Fuel (LSY
2.0L L4 Engine) 0360 or
Recommended Fuel (LGY
3.0L V6 and LT4 6.2L
V8 Engines) 0361.
If the light remains on, see
your dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an
Emissions Inspection/
Maintenance test, the test
equipment will likely connect
to the vehicle's Data Link
Connector (DLC).
The DLC is under the
instrument panel to the left of
the steering wheel.
Connecting devices that are
not used to perform an
Emissions Inspection/
Maintenance test or to service
the vehicle may affect vehicle
operation. See Add-On
Electrical Equipment 0372.
See your dealer if assistance
is needed.
