Starting and operating/Vehicle Dynamics Control system
! 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. Use this
mode in driving situations where the
vehicle dynamic performance will improve
without decreasing engine torque control.
When you press the switch briefly during
engine operation, the traction mode in-
dicator light and the Vehicle Dynamics
Control OFF indicator light on the combi-
nation meter illuminate. When you press
the switch again to reactivate the Vehicle
Dynamics Control system, the traction
mode indicator light and the Vehicle
Dynamics Control OFF indicator light turn
off.
! Vehicle Dynamics Control OFF
mode
This mode allows only the ABS control.
When you press the switch for more than
approximately 2 seconds during engine
operation, the Vehicle Dynamics Control
OFF indicator light on the combination
meter illuminates. When you press the
switch again to reactivate the Vehicle
Dynamics Control system, the Vehicle
Dynamics Control OFF indicator light
turns off.
Creating an adequate driving wheel slip by
deactivating the Vehicle Dynamics Control
system temporarily may help to escape
from the following situations. Use the
Vehicle Dynamics Control OFF mode as
necessary.
. a standing start on a steeply sloping
road with a snowy, gravel-covered, or
otherwise slippery surface
. extrication of the vehicle when its
wheels are stuck in mud or deep snow
You should not deactivate the Vehicle
Dynamics Control system except under
the above-mentioned situations.
NOTE
. If you turn the ignition switch to the
“LOCK”/“OFF” position with the Vehi-
cle Dynamics Control system deacti-
vated, the system will be automatically
reactivated the next time the engine is
started.
. If you press and hold the switch for
30 seconds or longer, the Vehicle
Dynamics Control OFF 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”/“OFF” position and restart the
engine.
. When the Vehicle Dynamics Control
OFF mode is selected, the vehicle’s
running performance is comparable
with that of a vehicle that does not
have a Vehicle Dynamics Control sys-
tem. Do not deactivate the Vehicle
Dynamics Control system except when
absolutely necessary.
. Even when the Vehicle Dynamics
Control OFF mode is selected, compo-
nents of the brake control system may
still activate. When the brake control
system is activated, the Vehicle Dy-
namics Control operation indicator
light illuminates.
