CONTROLS AND INSTRUMENTS
Four Wheel Drive (4WD) Model
V
CAUTION
Even a 4WD vehicle does not exempt you from safe driving practices. Operate
the accelerator pedal, steering wheel and brake pedal with the same level of
caution as when driving a standard rear-wheel drive vehicle.

ADVICE
Before using a vehicle that has not been driven for a long period, check the
engine, transmission, and transfer case for oil leakage and make sure the oil is
at the required levels. If the oil levels are too low, oil is not distributed sufficiently
to all components, causing breakdown of these systems.
Start the engine and run it at idle at least 5 minutes. Make sure that the engine
produces no abnormal noise. Stop the engine, inspect the transfer case for
oil leaks, check that the oil is filled up to the specified level, and then drive the
vehicle approximately 50 meters (164 ft) forward at a speed of approximately
15 km/h (9 MPH) with the vehicle unloaded. In the case of an FTS model (6HK1
engine model), the inside of the transfer case is lubricated with oil when the
vehicle is driven forward.
Refer to "Starting the Engine" on page 4-4 to learn how to warm up the engine.

NOTE
FSS model, FTS model (6HH1 engine model)
The part-time 4WD model allows selecting either two wheel drive (2WD) mode
or 4WD mode using the 4WD switch. In addition, the transfer gear control switch
also provided on the part-time 4WD model allows you to change between the
"HIGH (high-speed)" range and "LOW (low-speed)" range.
FTS model (6HK1 engine model)
The full-time 4WD model vehicle distributes engine power to all wheels at all
times while driving. The center differential lock switch on the full-time 4WD
model allows the front and rear axles to be directly connected together. In
addition, the transfer gear control switch on the full-time 4WD model allows
you to change between the "HIGH (high-speed)" range and "LOW (low-speed)"
range.
