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). See Vehicle
Speed Messages 0136.
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) 0122.
Tachometer
The tachometer displays the engine
speed in revolutions per minute (rpm).
For vehicles with 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
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.
Engine Coolant
Temperature Gauge
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.

112 INSTRUMENTS AND CONTROLS
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 0251 for more
information.Safety Belt Reminders

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.
Passenger Safety Belt Reminder
Light
There is a passenger safety belt
reminder light near the passenger
airbag status indicator. See Passenger
Sensing System 073.
When the vehicle is started, this light
flashes and a chime may come on to
remind passengers to fasten their

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, seeAirbag System 067.
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 0134.
Passenger Airbag Status
Indicator
The vehicle has a passenger sensing
system. See Passenger Sensing System
0 73 for important safety information.
The passenger airbag status indicator
is in the overhead console.
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 a
