Four-wheel drive system
H2 (high speed position, two-
wheel drive)
Use this for normal driving on dry
hard-surfaced roads. This position
gives greater economy, quietest
ride and least wear.
H4 (high speed position, four-
wheel drive)
Use this for driving only on tracks
that permit the tires slide, like off-
road, icy or snow-covered roads.
This position provides greater trac-
tion than two-wheel drive.
The four-wheel drive indicator
light comes on
L4 (low speed position, four-
wheel drive)
Use this for maximum power and traction. Use L4 for climbing or descend-
ing steep hills, off-road driving, and hard pulling in sand, mud or deep
snow.
The four-wheel drive and low speed four-wheel drive indicator lights
come on
The A.D.D. can be engaged or disengaged by the shifting operations
described in the following shifting procedures.

■ Operating conditions of emergency brake signal
When the following conditions are met, the emergency brake signal will oper-
ate:
● The emergency flashers are off.
● Actual vehicle speed is over 55 km/h (35 mph).
● The system judges from the vehicle deceleration that it is a sudden braking
operation.
■ Automatic system cancelation of emergency brake signal
The emergency brake signal will be canceled in any of the following situa-
tions:
● The emergency flashers are turned on.
● The system judges from the vehicle deceleration that is not a sudden brak-
ing operation.

WARNING
■TRC/A-TRC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC/A-TRC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ Hill-start assist control does not operate effectively when
● Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, the hill-start assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not attempt to use
the hill-start assist control to hold the vehicle on an incline, as doing so
may lead to an accident.
■ When the TRC/VSC/Trailer Sway Control is activated
The slip indicator flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator flashes.
■ When the TRC/A-TRC/VSC/Trailer Sway Control systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/A-TRC/VSC/Trailer Sway Control systems off
unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC, A-TRC, VSC, Trailer Sway Control, hill-start assist control
and downhill assist control systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

■ System malfunction
In the following cases, have your vehicle checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
● The downhill assist control system indicator does not come on when the
engine switch is turned to the “ON” position (vehicles without smart entry &
start system) or IGNITION ON mode (vehicles with smart entry & start sys-
tem).
● The downhill assist control system indicator does not come on when the
“DAC” switch is pressed.
● The slip indicator comes on.
WARNING
■When using downhill assist control system
● Do not rely overmuch on the downhill assist control system. This function
does not extend the vehicle’s performance limitations. Always thoroughly
check the road conditions, and drive safely.
● Vehicles with manual transmission: Drive in a low gear. Driving in a high
gear when using downhill assist control system may cause the engine to
stall, which may lose the brake effectiveness and lock the tires, resulting in
an accident.
● Vehicles with manual transmission: On a steep slope, use the engine brak-
ing efficiently. If the vehicle is driven in N or with the clutch pedal
depressed on a steep slope, the load on the brake increases and con-
trolling the vehicle speed may be impossible, resulting in an accident.
■ The system may not operate on the following surfaces, which may lead
to an accident causing death or serious injury
● Slippery surfaces such as wet or muddy roads
● Icy surface
● Unpaved roads
