●If the engine coolant temperature is too low, the four-wheel drive control
system may not be able to shift. When the engine is warmer press the
switch again.
If the low speed four-wheel drive indicator light or the center differential lock
indicator light continues to blink even after attempting the above, there may
be a malfunction in the engine, the brake system or the four-wheel drive sys-
tem. In this case, you may not be able to shift between H4 and L4, and the
center differential lock may not be operable. Have the vehicle inspected by
your Toyota dealer immediately.
WARNING
■ While driving
Never move the four-wheel drive control switch if the wheels have lost t\
rac-
tion. Doing so may cause an accident resulting in death or serious injury.
■ When the vehicle is parked
If the shift lever is moved before the low speed four-wheel drive indicator
turns on/off, the transfer mode may not be shifted completely. The transfer
mode disengages both the front and rear driveshafts from the powertrain
and allows the vehicle to move regardless of the shift position. (At this time,
the indicator blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in
P. You or someone else could be seriously injured. You must complete the
shifting of the transfer mode.
NOTICE
■ To prevent damage to the center differential
● For normal driving on dry and hard surface roads, unlock the center differ-
ential.
● Unlock the center differential after the wheels are out of the ditch or off the
slippery or bumpy surface.
● Do not push the center differential lock/unlock switch when the vehicle is
turning or when its wheels are spinning freely off the ground.
