■Shifting from “4L” to “4H”
1 Stop the vehicle completely
and continue to depress the
brake pedal.
2 Shift the shift lever to N.
3 Push and shift the front-
wheel drive control switch to
“4H”.
The “4L” indicator will go off.
■When the front-wheel drive con-
trol switch is shifted to “4L”
VSC is automatically turned off.
■If the “4H” indicator flashes
The transfer mode may not suc-
cessfully change. Drive straight
ahead while accelerating or deceler-
ating, or drive in reverse.
■If the “4H” indicator is ON and
the “4L” indicator continues to
flash
A message will be displayed in the
multi-information display. Follow a
message, shift the shift lever to D or
R and drive the vehicle slowly, then
stop.
■If the “4H” indicator continues
to flash and the “4L” indicator
is ON
A message will be displayed in the
multi-information display. Follow a
message, shift the shift lever to D or
R and drive the vehicle slowly, then
stop.
■If the “4H” indicator is ON and
the “4L” indicator continues to
flash and a buzzer sounds
The shift lever is not in N and/or the
vehicle is moving . Stop the vehicle
completely, shift th e shift lever to N
and make sure that the indicator
stops flashing.
■If the “4H” indicator continues
to flash and the “4L” indicator
is ON and a buzzer sounds
The shift lever is not in N and/or the
vehicle is moving. Stop the vehicle
completely, shift the shift lever to N
and make sure that the indicator
stops flashing
■If the “4H” and “4L” indicator
flashes rapidly
There may be a malfunction in the
four-wheel drive system. Have the
vehicle inspected by your Toyota
dealer immediately.
■Four-wheel drive usage fre-
quency
You should drive in four-wheel drive
for at least 10 miles (16 km) each
month. This will assure that the front
drive components are lubricated.
WARNING
■Shifting the front-wheel drive
control switch from “2H” to
“4H” while driving
Never operate the front-wheel
drive control switch if the wheels
are slipping. Stop the slipping or
spinning before shifting.
■When the vehicle is parked
If the shift lever is moved before
the “4L” indicator turns on/off, the
transfer mode may not be shifted
completely. The transfer mode
disengages both the front and
rear driveshafts from the power-
train and allows the vehicle to
move regardless of the shift posi-
tion. (At this time, the indicator
blinks and the buzzer sounds.)
Therefore, the vehicle is free to
roll even if the automatic trans-
mission is in P. You or someone
else could be seriously injured.
You must complete the shifting of
the transfer mode before placing
transmission in P.

AUTO LSD system*
The AUTO LSD system aids
traction by using the trac-
tion control system to con-
trol hybrid system
performance and braking
when one of the drive
wheels begins to spin. The
system should be used only
when one of the drive
wheels spinning occurs in a
ditch or rough surface.

Crawl Control*
Allows travel on extremely
rough off-road surfaces at a
fixed low speed without
pressing the accelerator or
brake pedal. Minimizes loss
of traction or vehicle slip
when driving on slippery
road surfaces, allowing for
stable driving.
WARNING
■When using Crawl Control
function
Do not rely solely on the Crawl
Control function. This function
does not extend the vehicle’s per-
formance limitatio ns. Always thor-
oughly check the road conditions,
and drive safely.
■These conditions may cause
the system not to operate
properly
When driving on the following sur-
faces, the system may not be able
to maintain a fixed low speed,
which may result in an accident:
●Extremely steep inclines.
●Extremely uneven surfaces.
●Snow-covered roads, or other
slippery surfaces.
