Warning Lights, Gauges,
and Indicators
Warning lights and gauges can signal
that something is wrong before it
becomes serious enough to cause an
expensive repair or replacement.
Paying attention to the warning lights
and gauges could prevent injury.
Some warning lights come on briefly
when the engine is started to indicate
they are working. When one of the
warning lights comes on and stays on
while driving, or when one of the
gauges shows there may be a problem,
check the section that explains what
to do. Waiting to do repairs can be
costly and even dangerous.

118 INSTRUMENTS AND CONTROLS
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 0148.
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) 0132.
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.

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.

. 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.

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 a
problem with the lights or the
passenger sensing system. See your
