STRUCTURE AND OPERATION
FLUID COOLER & FLUID WARMER SYSTEM : System Description
INFOID:0000000009464202
CVT FLUID COOLER SCHEMATIC
COMPONENT DESCRIPTION
CVT Oil Warmer
• The CVT oil warmer (1) is installed on the front part of transaxle
assembly.
• When engine is started while engine and CVT are cold, engine coolant temperature rises more quickly than CVT fluid tempera-
ture. CVT oil warmer is provided with two circuits for CVT and
engine coolant respectively so that warmed engine coolant warms
CVT quickly. This helps shorten CVT warming up time, improving
fuel economy.
• A cooling effect is obtained when CVT fluid temperature is high.
Heater Thermostat
• The heater thermostat (1) is insta lled on the front part of transaxle
assembly.
• The heater thermostat open and close with set temperature.
SHIFT LOCK SYSTEM
SHIFT LOCK SYSTEM : System DescriptionINFOID:0000000009464203
The shift lever cannot be shifted from the “P” positi on unless the brake pedal is depressed while the ignition
switch is set to ON. The shift lock is unlocked by turn ing the shift lock solenoid ON when the ignition switch is
set to ON, the park position switch is turned ON (selec tor lever is in “P” position), and the stop lamp switch is
turned ON (brake pedal is depressed) as shown in the oper ation chart in the figure. Therefore, the shift lock
solenoid receives no ON signal and the shift lock remains locked if all of the above conditions are not fulfilled.
However, selector operation is allowed if the shift lock release button is pressed.

Gear shifting is performed in all shifting ranges from the lowest to the
highest gear ratio.
DS Position
Pressing down the accelerator pedal allows to drive the vehicle with
a feeling of M/T-like gear shifting.
Hill Climbing And Descending Control
If a downhill is detected with the accelerator pedal is released, the system performs downshift to increase the
engine brake force so that vehicle may not be accelerat ed more than necessary. If a climbing hill is detected,
the system improves the acceleration performance in re-acceleration by limiting the gear shift range on the
high side.
NOTE:
For engine brake control on a downhill, the control can be stopped with CONSULT.
Control In Acceleration
From change of the vehicle speed or accelerator pedal pos ition, the acceleration request level of the driver or
driving scene is evaluated. In start or acceleration duri ng driving, the gear shift characteristics with linearity of
revolution increase and vehicle speed increase ar e gained to improve the acceleration feel.
