1-7. Safety information
■Operating conditions (front airbags)
●The SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col-
lision when the vehicle impacts straight into a fixed barrier that does not move
or deform.
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed thresh old level, the SRS front airbags and the
seat belt pretensioners ma y not activate together.
●The SRS front passenger airbag will not activate, if there is not passenger sitting
in the front passenger seat. However, th e front passenger airbag may deploy, if
luggage is put in the seat or the seat belt is fastened, even if the seat is unoccu-
pied. ( P. 9 0 )
■Operating conditions (side and curtain shield airbags)
●The SRS side airbags and curtain shield ai rbags are designed to inflate when the
passenger compartment is subjected to a severe impact from the side.
●The SRS side airbag on the passenger seat will not activate if there is no passen-
ger sitting in the front passenger seat. Ho wever, the side airbag on the passen-
ger seat may deploy, if luggage is put in the seat, even if the seat is unoccupied.

Before driving
■Conditions under which the SRS airbags may deploy (inflate), other than a colli-
sion
The SRS front airbags may also deploy if a serious impact occurs to the underside of
your vehicle. Some examples are shown in the illustration.
The SRS curtain shield airbags may also deploy under the situations shown in the
illustration.
■Types of collisions that may not de ploy the SRS airbag (front airbags)
The SRS front airbags are generally not designed to inflate if the vehicle is involved
in a side or rear collision, if it rolls over, or if it is involved in a low-speed frontal colli-
sion. But, whenever a collision of any type causes sufficient forward deceleration of
the vehicle, deployment of th e SRS front airbags may occur.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or vehicle falling
●The angle of vehicle tip-up is marginal.
●The vehicle skids and hits a curb stone.
●Collision from the side
●Collision from the rear
●Vehicle rollover

Before driving
Deactivating the curtain shield airbags in a vehicle rolloverON/OFF (Hold for a few seconds)
The “RSCA OFF” indicator light
turns on. (Only when the engine
switch is in the “ON” position.)
■The switch only should be used
In a situation where inflation is not desired (such as during extreme off-road driv-
ing).
■Operating conditions when the “RSCA OFF” indicator is on
●The curtain shield airbag and seat belt pretensioner will not activate in a vehicle
rollover.
●The curtain shield airbag will activate in a severe side impact.
CAUTION
■For normal driving
Make sure the “RSCA OFF” indicator light is no t turned on. If it is left on, the curtain
shield airbag will not activate in the event of an accident, which may result in death
or serious injury.

When driving
Rear height control air suspension
The rear height control air suspension adjusts the rear vehicle height in
accordance with driving conditions. There are 3 selectable modes, “HI”
(high), “N” (normal), and “LO” (low).
■Height control switch
“▲ ” (Up) switch
“ ▼ ” (Down) switch
“OFF” switch
Push while the vehicle is
stopped. The “OFF” indicator
light will come on, and the vehi-
cle height will be fixed in the
current mode. Push the switch
again to turn the system back
on.

2-4. Using other driving systems
Height control indicator lightsIf you change the vehicle height mode, the indicator lights change as fol-
lows: • The current mode indicator light w ill turn off, and the selected mode
indicator light will begin flashing.
• Once the change in vehicle height is complete, the selected mode indicator light will change fr om flashing to continuously lit.
■Operating conditions
●The engine must be running.
●Vehicle speed must be within the acce ptable range for the selected mode.
■Automatic change in vehicle height
If the vehicle speed exceeds 19 mph (30 km/h) when in the high mode, or 7 mph
(12 km/h) when in the low mode, normal mode is automatically selected.
■Turning off the rear height control air suspension
●The system will remain off until the switch is pushed again, even if the engine
switch is turned off.
●Even if the rear height control air suspen sion is turned off, the system automati-
cally selects the normal mode if the vehicle’s speed exceeds 19 mph (30 km/h).
■Automatic leveling function
The vehicle is adjusted to a fixed height for each mode, regardless of the number of
occupants and the luggage load.
