BACK-UP CONTROL (ENGINE BRAKE)
If the selector lever is shifted to “2” position while driving in D4 (O/D)
or D
3 , great driving force is applied to the clutch inside the transaxle.
Clutch operating pressure (line pressure) must be increased to deal
with this driving force.
DURING SHIFT CHANGE
The line pressure is temporarily reduced corresponding to a change
in engine torque when shifting gears (that is, when the shift solenoid
valve is switched for clutch operation) to reduce shifting shock.
AT LOW FLUID TEMPERATURE

Fluid viscosity and frictional characteristics of the clutch facing change with fluid temperature. Clutch
engaging or band-contacting pressure is compensated for, according to fluid temperature, to stabilize
shifting quality.

The line pressure is reduced below 60°C (140°F) to prevent
shifting shock due to low viscosity of A/T fluid when temperature
is low.

Line pressure is increased to a maximum irrespective of the
throttle opening when fluid temperature drops to −10°C (14°F).
This pressure rise is adopted to prevent a delay in clutch and
brake operation due to extreme drop of fluid viscosity at low
temperature.
Shift ControlECS00CTD
The shift is regulated entirely by electronic control to accommodate vehicle speed and varying engine opera-
tions. This is accomplished by electrical signals transmitted by the revolution sensor and the ECM (accelerator
pedal position sensor). This results in improved acceleration performance and fuel economy.

ALL MODE 4X4 SYSTEM

4WD MODE SWITCH
AUTO Mode

Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.

4WD mode makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.

On roads which do not require 4WD, AUTO mode contributes to improved fuel economy by driving in con-
ditions close to front-wheel drive.

Sensor inputs determine the vehicle's turning condition, and tight cornering/braking are controlled by dis-
tributing optimum torque to rear wheels.
LOCK Mode

Front/rear wheel torque distribution is fixed, ensuring stable driving when climbing slopes.

Vehicle will switch automatically to AUTO mode if vehicle speed increases. If vehicle speed then
decreases, the vehicle automatically returns to direct 4-wheel driving conditions.

LOCK mode will change to AUTO mode automatically, when the vehicle speed exceeds approx. 30 km/h
(19 MPH). The LOCK indicator light keeps illuminating.
NOTE:
If there is a significant difference in pressure or wear between tires, full vehicle performance is not available.
LOCK mode may be prohibited, or speeds at which LOCK mode is enabled may be restricted detecting tire
conditions.
2WD Mode
Vehicle is in front-wheel drive.
NOTE:

If front wheels are slipping in 2WD mode, do not switch to AUTO or LOCK. This can cause difficulties for
the system.

Even if the 4WD mode switch is in 2WD mode, the 4WD control unit occasionally automatically change to
AUTO mode depending on the driving condition (For example; Depressing the acceleration firmly). This is
not malfunction. However, 4WD indicator lamp dose not illuminate.
4WD INDICATOR LAMP AND LOCK INDICATOR LAMP
The following is the indications of indicator lamp.
4WD WARNING LAMP
Turns ON when there is a malfunction in 4WD system. It indicates that the vehicle is in fail-safe mode and
change to front-wheel drive or shifting driving force-4WD (Rear-wheels still have some driving torque).
Also turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1
seconds after the engine starts if system is normal.

Self-Diagnosis FunctionEKS00F32
DESCRIPTION

Diagnosis function consists of the self-diagnosis mode performed automatically and the CONFIRMATION/
ADJUSTMENT mode operated manually.

Self-diagnosis mode checks for connections between the units constituting this system, analyzes each
individual unit at the same time, and displays the results on the LCD screen.

CONFIRMATION/ADJUSTMENT mode is used to perform trouble diagnosis that require operation and
judgment by an operator (trouble that cannot be automatically judged by the system), to check/change the
set value, and to display the History of Errors of the navigation system.
DIAGNOSIS ITEM
Mode Description
Self-diagnosis

NAVI Control unit diagnosis (DVD-ROM drive will not be diagnosed when no
map DVD-ROM is in it.).

Performs diagnosis of each unit and connections between control unit and GPS
antenna, as well as between control unit and each unit.
Confirmation /
AdjustmentDisplayColor tone and shading of the screen can be checked by the display of a color bar
and a gray scale.
Vehicle signalsAnalyzes the following vehicle signals: Vehicle speed signal, light signal, ignition
switch signal, and reverse signal.
History of ErrorsDiagnosis results previously stored in the memory (before turning ignition switch
ON) are displayed in this mode. Time and location when/where the errors occurred
are also displayed.
NavigationDisplay Longitude
& LatitudeDisplay the map. Use the joystick to adjust position. Longitude and latitude will be
displayed.
Speed CalibrationUnder ordinary conditions, the navigation system distance measuring function will
automatically compensate for minute decreases in wheel and tire diameter caused
by tire wear or low pressure. Speed calibration immediately restores system accu-
racy in cases such as when distance calibration is needed because of the use of
tire chains in inclement weather.
Angle AdjustmentCorrects difference between actual turning angle of a vehicle and turning angle of
the car mark on the display.
Initialize LocationThis mode is for initializing the current location. Use when the vehicle is trans-
ported a long distance on a trailer, etc.
Feature Restriction SettingOperations of navigation system that are performed while driving can be restricted
by using this function.

Display Longitude & Latitude

Adjust the pointer with using the joystick and touch “Set”.

The longitude and latitude are displayed.
Speed Calibration

During normal driving, distance error caused by tire wear and
tire pressure change is automatically adjusted for by the auto-
matic distance correction function. This function, on the other
hand, is for immediate adjustment, in cases such as driving with
tire chain fitted on tires.
Angle Adjustment

Adjusts turning angle output detected by the gyroscope.
