WARNING
■The electronically modulated air suspension must be turned off in the
following circumstances:
Otherwise, the automatic leveling function may cause the vehicle’s height to
change, and you may catch part of your body in the vehicle, resulting in an
unexpected accident:
● When driving through water such as shallow streams (Put the veh icle
height in “HI” mode and turn off the electronically modulated a ir suspen-
sion. Drive at 18 mph [30 km/h] or slower.)
● When jacking up the vehicle, installing tire chains or tying th e vehicle with
chains/wires for transportation via flat bed truck (Turn the system to the
manual mode and stop the engine.)
● When the vehicle must be towed (Put the vehicle height in “N” mode and
turn the system to the manual mode.)
● When the vehicle gets stuck (Turn the system to the manual mode .)
● When disconnecting a trailer (Put the vehicle height in “N” mod e and turn
the system to the manual mode.)
■ Selecting the correct height mode
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the vehicle, as w ell as dan-
gerous handling characteristics, which may lead to fatal or inj ury accidents.
● Before you lower the vehicle’s height, check under the vehicle to make
sure that no one is there.
● “HI” mode should only be used when driving on rough roads, for example
when driving off-road.
Because the vehicle’s center of gravity will become higher when in the
mode, the vehicle may become unstable when turning abruptly, resulting
in an accident.
● Do not select “HI” mode when you load cargo on the roof luggage carrier.
Because the vehicle’s center of gravity will become higher when in the
mode, the vehicle may become unstable when turning abruptly, resulting
in an accident.

If the “4LO” indicator, “4HI” indicator or the center different ial lock indi-
cator blinks
● If the “4LO” indicator continues to blink when shifting between “4H” and “4L”,
stop the vehicle completely, move the shift lever to N and oper ate the switch
again.
● If the shift lever is moved before the “4LO” indicator turns on /off, the transfer
mode may not be shifted completely. The transfer mode disengage s both
the front and rear driveshafts from the powertrain and allows the vehicle to
move regardless of the shift position. (At this time, the indic ator blinks and
the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic tr ansmission 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 completely, return t he shift lever to
N, and confirm that the shift was completed (The indicator turn s on/off).
● If the engine coolant temperature is too low, transfer mode may not be able
to shift. When the engine is warmer, turn the switch again.
If the “4LO” indicator, “4HI” i ndicator or the center different ial lock indicator
continues to blink even after attempting the above, there may b e a malfunc-
tion in the engine, the brake system or the four-wheel drive sy stem. In this
case, you may not be able to shift between “2WD” and “4H”, “4H” and “4L”,
and the center differential lock may not be operable. Have the vehicle
inspected by your Toyota dealer immediately.
■ Shifting to the “4L” position
The VSC off indicator will come on.
If the center differential is locked, VSC is automatically turn ed off.

AUTO LSD mode
Stop the vehicle completely,
and press for more than 3
seconds. The “AUTO LSD” and
VSC off indicators will come on.
To turn off the system, press
again.
The AUTO LSD system aids trac tion by using the traction con-
trol system to control engine 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.

■ If the brake system overheats
The system will cease operation and a buzzer will alert the driver. At this time,
the “TRAC OFF” indicator will come on. Stop the vehicle in a safe place.
(There is no problem with continuing normal driving.) The syste m will be auto-
matically restored after a short time.
WARNING
■ To avoid an accident
Failure to do so, a much greater steering effort and more careful cornering
control will be required.
● Do not use the AUTO LSD system in conditions other than when on e of
the drive wheels spinning occurs in a ditch or rough surface.
● Do not drive with the AUTO LSD system continuously turned on.

NOTICE
■To prevent water damage
● Take all necessary safety measures to ensure that water damage to the
engine or other components does not occur.
● Water entering the engine air intake will cause severe engine damage.
● Water entering the automatic transmission will cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ulti-
mately damage.
● Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the differentials, transmission and
transfer case, reducing the gear oil’s lubricating qualities.
■ When you drive through water
If driving through water, such as when crossing shallow streams , first check
the depth of the water and the bottom of the riverbed for firmn ess. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
● Sand and mud that has accumulated in brake drums and around bra ke
discs may affect braking efficiency and may damage brake system compo-
nents.
● Always perform a maintenance inspection after each day of off-r oad driv-
ing that has taken you through rough terrain, sand, mud, or wat er. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.
