70 Instruments and Controls
Speedometer
The speedometer shows the
vehicle's speed in either kilometers
per hour (km/h) or miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
Each time the reset knob is pressed
with the engine control switch in the
ON position, the odometer/trip meter
shows ODO, TRIP A, and TRIP B in
this sequence. With the key
removed, the odometer and trip
meter continue to indicate for about
five minutes.
Odometer Check Switch
Press the Odometer Check switch
to display the odometer and trip
meter mileage after the key is
turned off. The fuel gauge will also
operate when this switch is pressed.
The DIC and some lights will
illuminate on the instrument panel.
Trip Odometer
The trip odometer shows how far
the vehicle has been driven since
the trip odometer was last reset.
Press the trip odometer reset stem
next to the odometer to switch
between the odometer and trip
odometer.To reset the trip odometer to zero,
press and hold the trip odometer
reset stem while TRIP A or TRIP B
is displayed. The engine control
switch should be in the ON position.
When the battery is disconnected,
TRIP A and TRIP B will be reset to
zero. The per trip fuel economy is
also reset by the TRIP B reset. See

When you turn the engine control
switch to the ON position, the
odometer/trip odometer shows what
was displayed the last time the
engine control switch was turned to
LOCK or ACC.
To set the odometer to display each
time you turn the engine control
switch to the ON position, turn the
engine control switch to LOCK or
ACC while the odometer is
displayed. With the reset stem
pressed, turn the engine control
switch to the ON position and then
within three seconds, turn the

LOCK or ACC position. Follow the
same procedure to cancel the
setting.
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm). The red zone
indicates a range of dangerous
engine speeds beyond permissable
levels. Do not drive your vehicle
with the needle in the red zone.
Caution
Exercise extreme care when
shifting down on a steep
downslope. The engine speed
may exceed the critical speed,
which can damage the vehicle.
Fuel Gauge
With the engine control switch in the
ON position, the fuel gauge
indicates about how much fuel is left
in the tank.To check the fuel level with the
engine control switch in the LOCK
position, press the Odometer Check
switch.
Fill the tank well before it
approaches empty. After filling up
the fuel tank, it takes awhile for the
fuel gauge needle to stabilize after
the engine control switch is turned
to the ON position. If the fuel tank is
filled while the engine is off, but the
engine control switch is in the ON
position, the fuel gauge needle
takes awhile to show the correct
reading.

298 Vehicle Care
Warning (Continued)
Consult your dealer before
replacing wheels. Never use
wheels that are not designed for
the vehicle. Doing so would
impede safe vehicle operation.
You should replace your tires when:
. Your tires are worn to a point
where 3.2 mm (4/32 in.) (front)
and 1.6 mm (2/32 in.) (rear) or
the cord or fabric is exposed.
. Your tire tread or sidewall is
cracked, cut or snagged deeply
enough to expose the core,
fabric or steel components.
. Your tire has a hump, bulge or
split.
. Your tire sustains a puncture, cut
or other damage that cannot be
correctly repaired because of the
size or location of the damage.
When replacing tires, you should
use the same size, load range and
construction type (bias or radial) as
the original tires on your vehicle. Use of any other size or type tire
may affect load carrying capacity,
ride, handling, speedometer/
odometer calibration, vehicle ground
clearance and tire clearance to the
chassis. If replacing only a single
tire, it should be put on the same
axle with other tires of equal
diameter.
When replacing or rotating tires, all
tires on an axle should be of the
same tread design and should have
the same outside diameter within
certain limitations, particularly on
LSD models. Consult your
authorized dealer or tire dealer.

If the original equipment tires are
low rolling tires, it is recommended
to use the LRRA tires shown in the
above table.
Refer to the emission control
identifiers on Greenhouse Gas
(GHG) emission plate for your
original equipment tires. Also,
please refer to “VIN, Weight Rating,
and Greenhouse Gas (GHG)
Emissions Plate” for the location of
the Greenhouse Gas (GHG)
emission plate. See Vehicle
Identification Number (VIN) 0353. Wheel Replacement
Recommendations
Wheels must be replaced if they
become damaged (for example:
bent, heavily rusted, leak air) or if
wheel nuts often become loose. Do
not use bent wheels that have been
straightened and do not use inner
tubes in leaking wheels which are
designed for tubeless tires. Such
wheels may have structural damage
and could fail without warning.
When replacing wheels for any
reason, the new wheels should be
equal in load capacity, diameter, width, offset and mounting types to
those originally installed in your
vehicle.
A wheel of the wrong size or type
may adversely affect wheel and
bearing life, brake cooling,
speedometer/odometer calibration,
stopping ability, headlight aim,
bumper height, vehicle ground
clearance and tire or tire chain
clearance on the body and chassis.
Replacement with "used" wheels is
not advised. They may have been
subjected to harsh treatment or very
high mileage and could fail without
warning.
