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.

INFOID:0000000009464219
TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of
the main electronically contro lled input/output parts is damaged.
If the vehicle shows following behaviors including “poor acceleration”, a malfunction of the applicable system
is detected by TCM and the vehicle may be in a fail-sa fe mode. At this time, check the DTC code and perform
inspection and repair according to the malfunction diagnosis procedures.

CAUTION:
• Always use shop paper. Never use shop cloth.
• Replace a drain plug gasket with new ones at the fi nal stage of the operation when installing.
• Use caution when looking into the drain hole as there is a risk of dripping fluid entering the eye.
• After replacement, always pe rform CVT fluid leakage check.
1. Select “Data Monitor” in “TRANSMISSION” using CONSULT.
2. Select “FLUID TEMP” and confirm t hat the CVT fluid temperature is 40°C (104 °F) or less.
3. Check that the selector lever is in the “P ” position, then completely engage the parking brake.
4. Lift up the vehicle.
5. Remove the drain plug and drain the CVT fluid from the oil pan. Refer to TM-387, "Exploded View"
.
6. Install the drain plug to oil pan. CAUTION:
Drain plug gasket use the old one.
7. Remove the overflow plug from converter housing.
8. Install the charging pipe set (KV311039S0) (A) into the overflow plug hole.
CAUTION:
Tighten the charging pipe by hand.
9. Install the ATF changer hose (B) to the charging pipe. CAUTION:
Press the ATF changer hose all the way onto the charging
pipe until it stops.
10. Fill approximately 3 liter (2-5 /8 lmp qt) of the CVT fluid.
11. Remove the ATF changer hose and charging pipe, then install the overflow plug.
NOTE:
Perform this work quickly because CVT fluid leaks.
12. Lift down the vehicle.
13. Start the engine.
14. While depressing the brake pedal, shift the selector leve r to the entire position from “P” to “DS”, and shift it
to the “P” position.
NOTE:
Hold the lever at each position for 5 seconds.
15. Check that the CONSULT “Data Monitor” in “FLUID TEMP” is 35°C (95 °F) to 45 °C (113 °F).
16. Stop the engine.
17. Lift up the vehicle.
18. Remove the drain plug, and then drain CVT fluid from oil pan. CVT fluid : Refer to
