TOW TRUCK TOWING

TOWING THE VEHICLE WITH REAR WHEELS RAISED (WITH FRONT WHEELS ON GROUND)
OR FRONT WHEELS RAISED
Never tow the vehicle with rear wheels raised (with front wheels on
ground) or front wheels raised as this may cause serious and expen-
sive damage to the transaxle. If it is necessary to tow it with rear
wheels raised or front wheels raised, always use a towing dolly
under the front wheels.
If the speed or distance must necessarily be greater, remove the
front and rear propeller shafts beforehand to prevent damage to the
transaxle.
Vehicle Recovery (Freeing a Stuck Vehicle) EAS000FM

Use the towing hook only, not other parts of the vehicle. Other-
wise, the vehicle body will be damaged.

Use the towing hook only to free a vehicle stuck in sand, snow,
mud, etc. Never tow the vehicle for a long distance using only
the towing hook.

The towing hook is under tremendous force when used to free a
stuck vehicle. Always pull the cable straight out from the front or
rear of the vehicle. Never pull on the hook at an angle.

Stand clear of a stuck vehicle.
WARNING:

Do not spin the tires at high speed. This could cause them
to explode and result in serious injury. Parts of the vehicle
could also overheat and be damaged.

PRECAUTIONS

Service NoticeEDS001V7

After overhaul refill the transfer with new transfer oil.

Check the oil level or replace the oil only with the vehicle parked on level ground.

During removal or installation, keep inside of transfer clear of dust or dirt.

Replace all tires at the same time. Always use tires of the proper size and the same brand and pattern.
Fitting improper size and unusual wear tires applies excessive force to vehicle mechanism and can cause
longitudinal vibration.

Disassembly should be done in a clean work area.

Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign matter.

Check for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.

All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.

Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.

Gaskets, seals, O-rings and lock nuts should be replaced any time when the transfer is disassembled.

In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, use it.

Observe the specified torque when assembling.

Clean and flush the parts sufficiently and blow-dry them.

Be careful not to damage sliding surfaces and mating surfaces.

Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transfer.
Wiring Diagrams and Trouble DiagnosisEDS001V8
When reading wiring diagrams, refer to the following:

GI-14, "How to Read Wiring Diagrams".

PG-2, "POWER SUPPLY ROUTING".
When performing trouble diagnosis, refer to the following:

GI-10, "How to Follow Trouble Diagnoses".

GI-23, "How to Perform Efficient Diagnosis for an Electrical Incident".

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.
