Hill descent control function

The hill descent control function will be in
standby mode when the X-mode is acti-
vated and the vehicle speed is less than
approximately 12 mph (20 km/h).
The function will operate when the vehicle
speed is less than approximately 12 mph
(20 km/h) and the accelerator ratio is less
than approximately 10%.
The function will turn off when the vehicle
speed is more than approximately 12 mph
(20 km/h) and the accelerator pedal is
depressed.
CAUTION
The braking power of the hill des-
cent control function may not be
sufficient when strong braking
power is needed (e.g., when towing
a trailer (Outback)).
NOTE
. Even while the hill descent control
function is operating, you can vary the
vehicle speed by using the brake pedal
or accelerator pedal.
. During braking by the hill descent
control function, the hill descent con-
trol indicator will flash.
. The hill descent control function is
operable regardless of the gradient of
the road.
. The hill descent control function
may be considered normal when the
following conditions occur.
An operating sound is heard
briefly from the engine compart-
ment while the hill descent control
function is operating.
The sensation of depressing the
brake pedal is different, (harder
than usual etc.) when the brake
pedal is depressed during hill des-
cent control function operation.
Hill descent control indicator
This indicator appears while the hill
descent control function is in the standby
mode. It flashes while the function is
operating. It will disappear when the
function is in the disabled mode. When
this function is changed from operational
to non-operational, it will disappear when
the vehicle speed reaches more than
approximately 18 mph (30 km/h).
