INSTRUMENTS AND CONTROLS 121
Speedometer
The speedometer shows the vehicle's
speed in kilometers per hour (km/h)
or miles per hour (mph).
This vehicle is equipped with an
overspeed warning device. When the
vehicle's speed reaches 120 km/h
(75 mph), a chime will sound.
A message also displays in the Driver
Information Center (DIC). SeeVehicle
Speed Messages 0151.
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
Trip Odometer
The trip odometer shows how far the
vehicle has been driven since the trip
odometer was last reset.
The trip odometer is accessed and
reset through the Driver Information
Center (DIC). See Driver Information
Center (DIC) 0136.
Tachometer
The tachometer displays the engine
speed in revolutions per minute (rpm).
On the base cluster, if the vehicle has
the Stop/Start system, when the
ignition is in ON/RUN, the tachometer
indicates the vehicle status. When
pointing to AUTO STOP, 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.
When the engine is on, the
tachometer will indicate the engine’s
revolutions per minute (rpm). The
tachometer may vary by several
hundred rpm’s, during Auto Stop
mode, when the engine is shutting off
and restarting.
A slight bump may be felt when the
transmission is determining the most
fuel efficient operating range.Caution
If the engine is operated with the
rpm’s 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’s in the
warning area.
Fuel Gauge

122 INSTRUMENTS AND CONTROLS
Uplevel Balanced Configuration
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. 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 may have
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.
Boost Gauge (Performance
Configuration Only)
This gauge indicates boost under
heavier throttle.
It displays the air pressure level in the
intake manifold before it enters the
engine's combustion chamber.
The gauge is automatically centered at
zero every time the engine is started.
Actual boost is displayed from this
zero point. Changes in ambient
pressure, such as driving in mountains
and changing weather, will slightly
change the zero reading.

INSTRUMENTS AND CONTROLS 123
Engine Oil Pressure Gauge
(Base Level Cluster)
The engine oil pressure gauge shows
the engine oil pressure
in kPa (kilopascals) when the engine is
running.
Oil pressure can vary with engine
speed, outside temperature, and oil
viscosity.
On some models, the oil pump will
vary engine oil pressure according to
engine needs. Oil pressure may change
quickly as the engine speed or load
varies. This is normal.If the oil pressure warning light or
Driver Information Center (DIC)
message indicates oil pressure outside
the normal operating range, check the
vehicle's oil as soon as possible. See
Engine Oil Messages
0144 and Engine
Oil 0250.
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check the
oil level as soon as possible. Add oil
if required, but if the oil level is
within the operating range and the
oil pressure is still low, have the
vehicle serviced. Always follow the
maintenance schedule for changing
engine oil.
Engine Oil Temperature
Gauge (Performance
Configuration Only)
This gauge shows the engine oil
temperature.
If the gauge pointer moves into the
high end, it means that the engine oil
has overheated. If the vehicle has been
operated under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as
soon as possible.
See Engine Oil 0250.

124 INSTRUMENTS AND CONTROLS
Engine Coolant
Temperature Gauge
Base Level Standard Theme Shown
Balanced Configuration Shown
This gauge measures the engine
coolant temperature.
The warning area at the far end of the
gauge may appear shaded or may be
colored red.
If the pointer approaches the warning
area or the shaded thermostat symbol,
the engine may be too hot.
Under some driving conditions,
including those listed below, it is
normal for the temperature to rise
above the usual operating range and
approach the far end of the gauge:
. Stop and go driving in heavy
traffic. .
High speed operation in warm
weather.
. Uphill driving.
. Trailer towing or hauling a
heavy load.
It is normal for the reading to
fluctuate.
If the gauge pointer reaches the
warning area or the shaded
thermostat symbol at the far end of
the gauge and remains there for more
than 30 seconds, the engine coolant
has overheated.
If the engine coolant has overheated,
pull over and stop the vehicle as soon
as it is safe to do so. Then, turn the
engine off immediately.
See Engine Overheating 0259.

Voltmeter Gauge (Base
Level Cluster)
Standard Theme
When the ignition is on, this gauge
indicates the battery voltage.
When the engine is running, this
gauge shows the condition of the
charging system. The gauge can
transition from a higher to lower or a
lower to higher reading. This is
normal. If the vehicle is operating
outside the normal operating range,
the charging system light comes on.
See Charging System Light 0127. Readings outside the normal operating
range can also occur when a large
number of electrical accessories are
operating in the vehicle and the
engine is left idling for an extended
period. This condition is normal since
the charging system is not able to
provide full power at engine idle. As
engine speeds are increased, this
condition should correct itself as
higher engine speeds allow the
charging system to create maximum
power.
The vehicle can only be driven for a
short time with the readings outside
the normal operating range. If the
vehicle must be driven, turn off all
accessories, such as the radio and air
conditioner, and unplug all chargers
and accessories.
Readings outside the normal operating
range indicate a possible problem in
the electrical system. Have the vehicle
serviced as soon as possible.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
There is a driver safety 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
safety 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 safety belt is buckled,
neither the light nor the chime
comes on.

There is a passenger safety belt
reminder light near the passenger
airbag status indicator. SeePassenger
Sensing System 079.
When the vehicle is started, this light
flashes and a chime may come on to
remind passengers to fasten their
safety belt. Then the light stays on
solid until the belt is buckled. This
cycle continues several times if the
passenger remains or becomes
unbuckled while the vehicle is moving.
If the passenger safety belt is buckled,
neither the chime nor the light
comes on.
The front passenger safety belt
reminder light and chime may turn 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 safety 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 074.
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. See
Airbag System Messages 0149.
Passenger Airbag Status
Indicator
The vehicle has a passenger sensing
system. See Passenger Sensing System
0 79. The overhead console has a

INSTRUMENTS AND CONTROLS 127
When the vehicle is started, the
passenger airbag status indicator will
light the symbol for on and off for
several seconds as a system check.
Then, after several more seconds, the
status indicator will light either the on
or off symbol to let you know the
status of the front outboard passenger
frontal airbag and knee airbag.
If the on symbol is lit on the
passenger airbag status indicator, it
means that the front outboard
passenger frontal airbag and knee
airbag are allowed to inflate.
If the off symbol is lit on the airbag
status indicator, it means that the
passenger sensing system has turned
off the front outboard passenger
frontal airbag and knee airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be aproblem with the lights or the
passenger sensing system. See your
dealer for service.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong with
the airbag system. To help avoid
injury to yourself or others, have
the vehicle serviced right away. See
Airbag Readiness Light
0126 for
more information, including
important safety information.
Charging System Light
On some vehicles the charging system
light comes on briefly when the
ignition is turned on, but the engine is
not running, as a check to show the
light is working. It should go out when the engine is started. For vehicles with
a reconfigurable cluster, this light may
not come on when the ignition is
turned on.
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.
See
