Driving
Lock the center differential when your
vehicle’s wheels get stuck in a ditch or
when driving on a slippery or bumpy
surface.
The center differential lock indicator will
come on.
Unlock the center differential after the
wheels have been freed, or after moving
to a flat, non-slippery surface.
To unlock the center differential, push the switch again.
■Shifting from H4 to L4Stop the vehicle completely with brake pedal held down.
Shift the shift lever to N.
Push and shift the four-wheel drive control switch to L4.
Maintain this condition until the low sp eed four-wheel drive indicator turns on.
■Shifting from L4 to H4
Stop the vehicle completely with brake pedal held down.
Shift the shift lever to N.
Push and shift the four-wheel drive control switch to H4.
Maintain this condition until the low sp eed four-wheel drive indicator turns off.
■The four-wheel drive control switch can be operated when
●The engine switch is in IGNITION ON mode.
●The shift lever is in the N position.
●The vehicle is stopped completely.
■The low speed four-wheel drive indicator light
The indicator light blinks while shifting between H4 and L4.
■Advice for driving on slippery roads
●If you shift the four-wheel drive control switch to L4 and the shift lever to the 2 range of
S or D (vehicles with paddle shift switches) while driving in steep off-road areas, the
output of the brake can be co ntrolled effectively by the Active TRAC, which assists the
driver to control the driving power of 4 wheels.
●Use the 1 range of S or D (vehicles with pa ddle shift switches) for maximum power and
traction when your wheels get stuck or when driving down a steep incline.

■The center differential lock indicator light
The indicator light blinks
while locking/unlocking the center differential.
■The center differential lock/unlock switch can be operated when
●The engine switch is in IGNITION ON mode.
●The vehicle speed is less than 62 mph (100 km/h).
■Locking/unlocking the center differential
●When the four-wheel drive control switch is in L4 with the center differential locked,
VSC is automatically turned off. (The center differential lock and VSC OFF indicator
lights come on.)
●If the operation is not completed, the center di fferential lock indicator blinks. If the indi-
cator light does not turn off when unlocking the center diff erential, drive straight ahead
while accelerating or decelera ting, or drive in reverse.
●If the center differential lock/unlock is no t completed within 5 seconds while the cruise
control system is on, cancel the cruise control system.
■If the low speed four-wheel driv e indicator light or the center differential lock indicator
light blinks
●If the low speed four-wheel drive indicator lig ht continues to blink when using the four-
wheel drive control switch, stop the vehicle completely, move the shift lever to N and
operate the switch again.
●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 po wertrain 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.
To complete the shifting, stop the vehicle co mpletely, return the shift lever to N, and
confirm that the shift was completed (the indicator turns on/off).
●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 operate 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 system. In this case, you may not be
able to shift between H4 and L4, and the cent er differential lock may not be operable.
Have the vehicle inspected by your Lexus dealer immediately.
