The downhill assist control system is a
system that assists the deceleration of
the engine brake when you drive down
a steep hill. When you are driving down
a hill with the four−wheel drive control
switch knob (full−time four−wheel drive
models) or multi−mode control switch
knob (multi−mode four−wheel drive
models) in the L4" position, push the
DAC" switch to limit the vehicle’s ac-
celeration. If the vehicle is traveling at
a speed of 25 km/h (15 mph) or less,
you can descend at a constant speed.
CAUTION
Do not rely excessively on the down-
hill assist control system. It may not
be able to maintain a low speed over
road surfaces or off−road surfaces on
which sliding can easily occur, such
as extremely steep slopes or icy or
muddy roads.
TO ACTIVATE THE DOWNHILL ASSIST
CONTROL SYSTEM1. Full−time four−wheel drive models Turn the four−wheel drive control
switch knob to the L4" position.
The system will not operate if the four−
wheel drive control switch knob is in the
H4" position. Multi−mode four−wheel drive mod-
elsTurn the multi−mode control
switch knob to the L4" position.
The system will not operate if the multi−
mode control switch knob is in the H4"
position. 2. In order to make full use of the en- gine brake, putting the transmission
in L" or 2" is recommended.
The system will operate even if the trans-
mission selector lever is in D", 4", 3"
or N". However, when it is in L" or 2"
the engine brake can also be utilized en-
abling the system to operate more effec-
tively.

3. Push the DAC" switch to turn the system on. The downhill assist con-
trol system indicator light on the in-
strument panel will come on.
Full−time four−wheel drive modelsIf the
downhill assist control system indicator
light flashes, the selector lever may be in
N" or the four−wheel drive control switch
knob may be in the H4" position.
If the indicator light does not come on
when the switch is pushed, contact your
Toyota dealer.

Multi−mode four−wheel drive modelsIf
the downhill assist control system indica-
tor light flashes, the selector lever may be
in N" or the multi−mode control switch
knob may be in the H2" or H4" position.
If the indicator light does not come on
when the switch is pushed, contact your
Toyota dealer.

With the vehicle traveling at a speed of
25 km/h (15 mph) or less, release your
foot from the accelerator or brake pedal
to activate the system. The vehicle will
descend the hill at a low speed. While the
system is operating, the slip indicator light
on the instrument panel will flash and the
stop lights and high mounted stoplight will
be lit.
If you push the DAC" switch to turn the
system off while it is in operation, the
system will stop operating gradually. The
downhill assist control system indicator
light will flash to alert the driver. To con-
tinue driving at a low speed, push the
DAC" switch to turn the system on. The slip indicator light and downhill assist
control system indicator light come on for
a few seconds when the engine switch is
turned to ON". If any of the indicator
lights does not come on when the engine
switch is turned on, contact your Toyota
dealer.
The brake actuator temperature increases
during continuous operation of the h
ill−
start assist control system, the active
traction control system and the vehicle
stability control system. If the brake ac-
tuator temperature becomes too high while
any of the systems is operating, a buzzer
will start to sound intermittently to indicate
that the downhill assist control system can
no longer operate. In this case, stop your
vehicle immediately at a safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.)

Keep in mind the following when driv-
ing.
The hill−start assist control system op-
erates for 5 seconds maximally. If both
the brake and accelerator pedals re-
main undepressed for longer than 5
seconds, the buzzer will sound at more
frequent intervals and the system will
gradually stop operating.
The hill−start assist control system is
not designed as a function for stopping
the vehicle on a uphill slope. When
stopping the vehicle, be sure to de-
press the brake pedal.
The brake actuator temperature increases
during continuous operation of the downhill
assist control system (four−wheel drive
models), the traction control system (two−
wheel drive models), the active traction
control system (four−wheel drive models),
the vehicle stability control system and
the AUTO LSD" system (two−wheel drive
models) on such as slippery roads. If the
brake actuator temperature becomes too
high while any of the systems is operat-
ing, a buzzer will start to sound intermit-
tently to indicate that the hill−start assist
control system can no longer operate. In
this case, stop your vehicle immediately at
a safe place. If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.)
At this time, the slip indicator light will
come on and the hill−start assist control
system stops operating temporarily in or-
der to protect the brake actuator. (Al-
though the h
ill−start assist control system
does not operate, it is no problem to con-
tinue your driving.) The system will be
automatically restored after a short time
and the slip indicator light goes out.

If there is any abnormality in the sys-
tem, the VSC OFF" warning light will
flash.
If the system malfunctions, the VSC OFF"
warning light will flash.
If the VSC OFF" warning light flashes,
there may be an abnormality in any of the

Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The anti−lock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.

The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.Your Toyota is equipped with a limited−slip
center differential (transfer). If one wheel
begins to spin, the limited−slip center dif-
ferential (transfer) is designed to aid trac-
tion by automatically transmitting driving
force to the wheels on the other drive
axle. It transmits driving force to the front
wheels if a rear wheel spins, and to the
rear wheels if a front wheel spins.
CAUTION
Do not start or run the engine while
your vehicle is supported by a jack.
The vehicle could be driven off the
jack and could pose a danger or re-
sult in serious injury.
NOTICE
Use only a spare tire of the same
brand, size, construction and load ca-
pacity as the original tires on your
Toyota because damage to the limit-
ed−slip differential could possibly oc-
cur with another tire type.
CY20013
