Low fuel warning light1) Low fuel warning light
The low fuel warning light illuminates
when the tank is nearly empty [Approxi-
mately 2.6 US gal (10 liters, 2.2 lmp gal)].
It only operates when the ignition switch is
in the “ON ”position.
NOTE
This light does not go out unless the
tank is replenished up to an internal
fuel quantity of approximately 4.0 US
gal (15 liters, 3.3 lmp gal).
CAUTION
Promptly put fuel in the tank when-
ever the low fuel warning light
illuminates. Engine misfires as a
result of an empty tank could cause
damage to the engine.
& Temperature gauge
1) Normal operating range
2) S# PREP indicator light
The temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ON ”position.
The coolant temperature will vary in
accordance with the outside temperature
and driving conditions. Instruments and controls
3-7
– CONTINUED –

3-8Instruments and controls
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range.
And high revving operation while the
engine is not warmed up enough should
be avoided.
When the engine is not warmed up
sufficiently, the S# PREP indicator light
turns on. While this indicator light is on,
the SI-DRIVE mode cannot be changed to
the Sport Sharp (S#) mode. For details
about the SI-DRIVE mode, refer to the “SI-
DRIVE (turbo and 3.0 L models) ”section
in chapter 7.
CAUTION
If the pointer exceeds the normal
operating range, safely stop the
vehicle as soon as possible.
Refer to “In case of emergency ”in
chapter 9. &
ECO gauge
The ECO gauge shows the difference
between the average rate of fuel con-
sumption and the current rate of fuel
consumption. Using the average rate of
fuel consumption since the trip meter was
last reset, if the current rate of fuel
consumption is higher than the average
rate of fuel consumption, the indicator
needle points to the “+ ” or right side, and if
the current rate of fuel consumption is
lower than the average rate of fuel
consumption, the indicator needle points
to the “ ” or left side. When the indicator
needle is pointing to the “+ ” or right side, it
indicates fuel-efficient driving. NOTE .
The ECO gauge shows only an
approximate indication. . After resetting the trip meter, the
average rate of fuel consumption is not
shown until driving 0.6 mile (1 km).
Until that time, the ECO gauge does notoperate.

2. Set the air flow control dial to the“”
position.
3. Set the temperature control dial all the
way left.
4. Set the fan speed control dial to the
desired speed.
When driving on a dusty road, set the air
inlet control button to the ON position.
WARNING
Continued operation in the ON posi-
tion may fog up the windows. Switch
to the OFF position as soon as the
outside dusty condition clears.
& Air conditioner operation
! Cooling or dehumidifying
For cooling and dehumidification of the
passenger compartment, air flows through
the instrument panel outlets:
1. Set the air inlet selection button to the
OFF position.
2. Set the air flow control dial to the “
”
position.
3. Set the air conditioner button to the “ ON ”position.
4. Set the temperature control dial to the
blue side.
5. Set the fan speed control dial at the desired speed. !
Defrosting or defogging
To direct warm air to the windshield and
front door windows:
1. Set the air outlet control dial to the “
” position.
2. Set the temperature control dial to the
red side.
3. Set the fan speed control dial at the
highest speed. NOTE
In a vehicle equipped with an air
conditioner, when the dial is placed inthe “
”position or “”position the
air conditioner compressor automati-
cally operates to quickly defog the
windshield. However the indicator on
the air conditioner button will not
illuminate. At the same time, the air
inlet selection is automatically set to“ outside air ”mode.
In this state, you cannot select “recir-
culation ”mode by manually pressing
the air inlet selection button.
Also, you cannot stop the air condi-
tioner compressor by pressing the air
conditioner button. Automatic climate control
system (if equipped) NOTE .
Operate the automatic climate con-
trol system when the engine is running. . The blower fan rotates at a low
speed when the engine coolant tem-
perature is low.
For efficient defogging or dehumidify-
ing in cold weather, press the “A/C ”
button.. Even when cooling is not necessary,
setting the temperature much lower
than the current outlet air temperature
turns on the air conditioner compres-
sor automatically and the “A/C ”indi-
cator light on the control panel illumi-nates.
The automatic climate control system
automatically controls outlet air tempera-
ture, fan speed, air flow distribution air-
inlet control, and air conditioner compres-
sor operation. It activates when the“ AUTO ”button is pressed, and is used to
maintain a constant, comfortable climate
within the passenger compartment.
The temperature can be set within a range
of 65 to 85 8F (18 to 32 8C).

mode. .The next time you turn on the
engine, after you turned off the engine
in the Sport (S) mode or Intelligent (I)
mode, the SI-DRIVE mode will stay in
the same mode as when the engine
was turned off.. While the engine is running, if the
CHECK ENGINE warning light/malfunc-
tion indicator lamp illuminates, the SI-
DRIVE mode changes to the Sport (S)
mode. In this case, it is not possible to
change to the Sport Sharp (S#) mode or
Intelligent (I) mode.. If there is a possibility that the
engine could overheat because of a
temperature increase of the engine
coolant, it is not possible to change to
the Sport Sharp (S#) mode. While the
vehicle is in the Sport Sharp (S#) mode,
it changes to the Sport (S) mode when
the engine coolant temperature in-
creases. For 3.0 L models, it also
changes to the Sport (S) mode when
the engine oil temperature increases. &
SI-DRIVE Sport Sharp (S#) switch
While driving in the Sport (S) mode or
Intelligent (I) mode, when you push the
steering wheel switch, it changes to the
Sport Sharp (S#) mode.
NOTE
While driving in Sport Sharp (S#) mode,
when you push the switch, it changes
to the former mode before Sport Sharp
(S#) mode. Rear viscous limited slip dif-
ferential (LSD) (if equipped)
CAUTION
. Never start the engine while a tire
on one side is jacked up, as the
vehicle may move.
. If one rear tire is spinning in mud,
avoid continued spinning at high
speed as this could adversely
affect the LSD.
. If a different size rear tire is
temporarily used (as in an emer-
gency), it will adversely affect the
LSD. Always replace it with a
regular size tire as soon aspossible.
The LSD provides optimum distribution of
power according to the difference in
revolutions between the right and left rear
wheels that may be caused by certain
driving conditions, thereby improving driv-
ing stability on snow-covered, muddy or
other slippery roads. Starting and operating

!Driving on grades
. Before going down a steep hill, slow
down and shift into lower gear (if neces-
sary, use 1st gear) in order to utilize the
engine braking effect and prevent over-
heating of your vehicle ’s brakes. Do not
make sudden downshifts. . When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating. . When driving uphill in hot weather, pay
attention to the water temperature gauge
pointer (for all vehicles) and AT OIL TEMP
warning light (for AT models) since the
engine and transmission are relatively
prone to overheating under these condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air
conditioner and stop the vehicle at the
nearest safe place. Refer to the “Engine
overheating ”section in chapter 9, and
“ Warning and indicator lights ”section in
chapter 3. NOTE
With AT models, the temperature of
engine coolant is less likely to rise to
the OVERHEAT zone in the “D ” posi-
tion than in the manual mode position. . If your vehicle has an automatic trans- mission, avoid using the accelerator pedal
to stay stationary on an uphill slope
instead of using the parking brake or foot
brake. That may cause the transmission
fluid to overheat. !
Parking on a grade
Always block the wheels under both
vehicle and trailer when parking. Apply
the parking brake firmly. You should not
park on a hill or slope. But if parking on a
hill or slope cannot be avoided, you
should take the following steps:
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks
under both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then
apply the parking brake; slowly release
the regular brakes.
5. Shift into 1st or reverse gear (manual
transmission) or “P ” (automatic transmis-
sion) and shut off the engine. Driving tips
