Continuously Variable Transmission; Continuously Variable Transmission Features - Subaru Ascent 2023 Manual

7-7. Continuously variable
transmission
WARNING
Do not shift from the "P" or "N"
position into the "D" or "R" position
while depressing the accelerator
pedal. This may cause the vehicle
to jump forward or backward.
CAUTION
. Observe the following precau-
tions. Otherwise, the transmis-
sion could be damaged.
– Shift into the "P" or "R" posi-
tion only after the vehicle has
completely stopped.
– Do not shift from the "D"
position into the "R" position
or vice versa until the vehicle
has completely stopped.
. Do not race the engine for more
than 5 seconds in any position
except the "N" or "P" position
when the brake is applied or
when chocks are used in the
wheels. This may cause the
transmission fluid to overheat.
. Never move the vehicle as fol-
lows. Doing so may result in an
unexpected accident or malfunc-
tion.
– Moving rearward by inertia
with the select lever set in a
forward driving position.
– Moving forward by inertia with
the select lever set in the "R"
position.
. When parking the vehicle, first
securely apply the parking brake
and then place the select lever in
the "P" position. Do not park for a
long time with the select lever in
any other position as doing so
could result in a dead battery.
& Continuously variable trans-
mission features
The continuously variable transmission is
electronically controlled and provides an
infinite number of forward speeds and 1
reverse speed. It also has a manual mode.
NOTE
. When the engine coolant tempera-
ture is still low, the transmission will
shift at higher engine speeds than
when the coolant temperature is

sufficiently high in order to shorten
the warm-up time and improve dri-
veability. The gearshift timing will
automatically shift to the normal
timing after the engine has warmed
up.
. Immediately after transmission fluid
is replaced, you may feel that the
transmission operation is somewhat
unusual. This results from invalida-
tion of data which the on-board
computer has collected and stored
in memory to allow the transmission
to shift at the most appropriate times
for the current condition of your
vehicle. Optimized shifting will be
restored as the vehicle continues to
be driven for a while.
. When driving under continuous hea-
vy load conditions such as when
towing a camper or climbing a long,
steep hill, the engine speed or the
vehicle speed may automatically be
reduced. This is not a malfunction.
This results from the engine control
function maintaining the cooling
performance of the vehicle. The
engine and vehicle speed will return
to a normal speed when the engine is
able to maintain the optimum cool-
ing performance after the heavy load
decreases. Driving under a heavy
load must be performed with ex-
