Adjust the mirror so that you can just
see the rear of your vehicle in the mir-
ror.
This mirror is equipped with auto anti
glare function. The function is designed
to reduce glare from the headlights of
the vehicle behind you during night
driving.
When the ignition key is inserted and
turned on, the inside rear view mirror al-
ways turns on in the automatic function
mode.
The indicator illuminates to show you that
the function is on. In automatic function mode, if the mirror
detects light from the headlights of the
vehicle behind you, the mirror surface
darkens slightly to reduce the reflected
light.
To turn off the automatic function, push
the “MIRROR” switch.
To turn on the automatic function again,
push the “MIRROR” switch.
Adjust it before driving so that the rear
view is in the best condition.
When the inside air temperature is low, it
may take little longer for the mirror to
darken in response to the detection of
headlights.
CAUTION
Do not adjust the mirror while the
vehicle is moving. Doing so may
cause the driver to mishandle the ve-
hicle and an accident may occur re-
sulting in death or serious injuries.
To ensure correct functioning of an
antiglare mirror sensor located on the
back side of the mirror, do not touch
or cover the sensor with your finger or
a piece of cloth, etc.

Idling for a long period with the air
conditioning on in stopandgo traffic.
Towing a trailer.
It is not a malfunction even if the needle
of the engine coolant temperature gauge
returns to “C” when the ignition switch is
turned to the “START” position.
NOTICE
 Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your ve-
hicle overheats” on page 282 in
Section 4.
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
It is not a malfunction even if the needle
of the tachometer returns to the bottom
position when the ignition switch is turned
to the “START” position.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.

er, if a front passenger uses an additional
seat cushion, the light may not flash even
when the seat belt is not buckled up.
If luggage or other load is placed on the
front passenger seat, depending on its
weight and how it is placed on the seat,
builtin sensors in the seat cushion may
detect the pressure, causing the reminder
light to come on. (d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging

the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when

is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.

This rear height control air suspension
controls the vehicle height depending
on the vehicle driving conditions. Select
your desired height among the “HI”
(high), “N” (normal) and “LO” (low)
modes with the height select switch.
(a) Vehicle height modes
“N” (normal) mode—
The vehicle height in this mode is standard.
Regardless of the number of occupants or the
luggage loading condition, the vehicle height
is always automatically adjusted to a fixed
height in this mode while the engine is
running.
This mode is suitable for ordinary driving. “HI” (high) mode—
The vehicle height is about 40 mm (1.6 in.)
higher at rear than the
“N” mode height.
This mode is suitable when driving on the
bumpy roads and through water.
However, when the vehicle speed exceeds
about 30 km/h (19 mph) or over in the
“HI” mode, the “N” mode is automatically
selected.
CAUTION
The “HI” mode should be used for
severe offroad driving condition
only. Because the vehicle’s center of
gravity is higher in this setting, the
vehicle may become unstable when
turning abruptly, resulting in accident.
“LO” (low) mode—
The vehicle height is about 20 mm (0.8 in.)
lower at rear than the “N” mode height.
This mode allows you easy access to the
vehicle (getting in and out) and easy load-
ing and unloading operation.
This mode is available when the vehicle
speed is under about 12 km/h (7 mph).
NOTICE
Use the “LO” mode when the vehicle
is stopped. Otherwise, when the ve-
hicle speed exceeds about 12 km/h (7
mph), “N” mode is selected automati-
cally. So be careful when you drive in
any place where the overhead height
is limited.
(b) Vehicle height mode changing con- dition
To change the vehicle height, it is necessary
to meet the following conditions.
The engine should be running.
The height control “OFF” indicator light
should go off.
