Starting and operating

& Vehicle Dynamics Control
mode switch (STI)

When the switch is pressed briefly or for
more than approximately 3 seconds during engine operation, the mode of the
Vehicle Dynamics Control System will be
changed.
! Vehicle Dynamics Control mode
When the ignition switch is on, this mode
is selected.
This mode enables all controls for ABS,
the Traction Control System, and the
Vehicle Dynamics Control system. Select
this mode for most driving situations.
When this mode is selected, the indicator
light “ ” on the combination meter turns
off.

! Traction mode
This mode restricts the functions of the
Traction Control System and Vehicle
Dynamics Control system and thus delays
utilizing their functions as a reaction to
vehicle behavior in comparison with the
Vehicle Dynamics Control mode. This
mode should be used in driving situations
where the vehicle dynamic performance
will improve without decreasing engine
torque control.
When the switch is pressed briefly during
engine operation, the indicator light “ ” on
the combination meter illuminates in
green. When the switch is pressed again
to reactivate the Vehicle Dynamics Control
system, the indicator light “ ” turns off.
! Vehicle Dynamics Control OFF
mode
This mode allows only the ABS control.
This mode should be used in an emergency situation such as getting out of
snow or mud.
When the switch is pressed for more than
approximately 3 seconds during engine
operation, the indicator light “ ” on the
combination meter illuminates in yellow.
When the switch is pressed again to
reactivate the Vehicle Dynamics Control
system, the indicator light “ ” turns off.

NOTE
. When a mode other than the Vehicle
Dynamics Control mode is selected,
the Vehicle Dynamics Control system
automatically reactivates itself the next
time the ignition switch is turned to the
“LOCK” position and the engine is
restarted.
. If the switch is held down for 10
seconds or longer, the indicator light
turns off, the Vehicle Dynamics Control
system is activated, and the system
ignores any further pressing of the
switch. To make the switch usable
again, turn the ignition switch to the
“LOCK” position and restart the engine.
. When the Vehicle Dynamics Contro l
OFF mode is selected, the vehicle’s
running performance is comparable
with that of a vehicle that does not
have a Vehicle Dynamics Control system. Do not deactivate the Vehicle
Dynamics Control system except when
absolutely necessary.
. Even when the Vehicle Dynamics
Control OFF mode is selected, components of the brake control system may
still activate. When the brake control
system is activated, the Vehicle Dynamics Control operation indicator
light illuminates.
