The 2WD/4WD operation indicator
lamp will blink during shifting process
from "4H" to "4L" or vice versa, as the
transfer passes through the neutral
Indicator lamp
position. Be sure to operate the drive
mode-selector until the 2WD/4WD
operation indicator lamp illuminates
again.
When parking, apply the parking brake
before stopping the engine and make
sure that the 2WD/4WD operation
indicator and the low range lamp are
not blinking during shifting process
between "4H" <–> "4L". Otherwise, the
vehicle could unexpectedly move even
and
if the automatic transmission is in the
"P" (PARK) position.
If, after a "4H" <–> "4L" selection has
been made, the 2WD/4WD operation
indicator continues blinking and the
desired range is not actually selected,
return the drive mode selector to its
previous position. Place the steering
wheel in the straight ahead position,
and
drive the vehicle forward, and release
the accelerator pedal. Next, hold down
the clutch pedal (with manual
transmission) or place the selector lever
in the "N" (NEUTRAL) position (with
automatic transmission) and make the
range selection again.
If the low range lamp blinks when you
attempt to make a "4H" <–> "4L"
selection, a "4H" <–> "4L" selection
cannot be made. Stop the vehicle and
release the accelerator pedal. Next,
hold down the clutch pedal (with
manual transmission) or place the
selector lever in the "N" (NEUTRAL)
position (with automatic transmission)
and make the range selection again.
The ESC function is suspended while
"4L" is selected
indicator lamp is
illuminated while these functions are
suspended. It does not indicate a
problem. When "2H" or "4H" is
selected, this lamp goes out and
function again. Refer to "ESC indicator
lamp, ESC OFF indicator lamp".

IMPORTANT
129) The "4L" range gives maximum torque
for low-speed driving on steep slopes, as
well as sandy, muddy, and other difficult
surfaces. On vehicles with automatic
transmission, do not exceed speeds of
approximately 70 km/h in "4L" range.
130) Do not drive your vehicle in the "4H"
or "4L" on dry paved roads and highways.
Doing so may result in excessive tyre wear,
increased fuel consumption, and possible
noise generation. It may also increase the
differential oil temperature, which may
damage the drive system. Further, the drive
train will be subjected to excessive loading,
resulting in oil leakage, component seizure,
or other serious problems. On dry paved
roads and highways, drive the vehicle in
"2H" only.
