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).

is too hot. Pull off the road,
stop the vehicle, and turn off
the engine as soon as
possible.
Engine Coolant
Temperature Gauge
(Uplevel)

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

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

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

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.
{Warning
If the airbag readiness light
stays on after the vehicle is
started or comes on while
driving, it means the airbag
system might not be working
properly. The airbags in the
vehicle might not inflate in a
crash, or they could even
inflate without a crash. To
help avoid injury, have the
vehicle serviced right away.
If there is a problem with the
airbag system, a Driver
Information Center (DIC)
message may also come on.
