tion in Eco drive mode
In Eco drive mode, heating/cooling
operations and the fan speed is con-
trolled to improve fuel efficiency.
Perform the following procedures to
increase the air conditioning perfor-
mance.
●Vehicles with automatic air condi-
tioning system: Turn eco air condi-
tioning mode off ( P.523)
●Adjust the fan speed ( P.516,
523)
●Cancel Eco drive mode
■Canceling a driving mode
●Sport mode is automatically can-

Multi-terrain Select
(AWD vehicles)
When driving over muddy,
sandy or rough road sur-
faces, Multi-terrain Select
selects a suitable driving
mode to switch AWD, brake
and drive force control to
perform control suitable for
the road condition.
WARNING
■Before using Multi-terrain
Select
Make sure to observe the follow-
ing precautions. Failure to
observe these precautions may
result in an unexp ected accident.
●Check that the Mud & Sand and
Rock & Dirt indicators are illumi-
nated before driving. Multi-ter-
rain Select will not operate
when the indicators are off.
●Do not rely solely upon the
Multi-terrain Select. This func-
tion is not inten ded to expand
the limits of the vehicle. If the
system is continuously used for
a long period of time, the load
on related parts increases and
the system may be unable to
operate normally, which may
lead to an accident. Thoroughly
check the road c onditions and
driving route before driving, and
drive with caution.

3604-5. Using the driving support systems
is approximately 25 km/h (16
mph) or more
If the vehicle speed drops below the
above speeds, the system automati-
cally switches to t he AWD control
suitable for each mode.
■When Multi-terrain Select brake
control temporarily stops oper-
ating
If Mud & Sand or Rock & Dirt mode
is continuously used for a long
period of time, the b rakes may over-
heat, and Multi-terrain Select brake
control may tempor arily stop operat-
ing.
●At this time, the buzzer sounds
intermittently and “Traction Con-
trol Turned OFF” is displayed on
the multi-inform ation display.
●If Multi-terrain Select brake control
stops operating, stop the vehicle
in a safe location as soon as pos-
sible
* and wait until the system
temperature decreases. Once the
display message on the multi-
information displa y turns off, the
brake control retu rns to normal.
Note that normal driving is still
possible even when Multi-terrain
Select brake control is not operat-
ing.
*: After stopping the vehicle, do not
stop the engine until the display
message has turned off.
■When Mud & Sand or Rock &
Dirt mode is canceled
In the following situations, Mud &
Sand mode or Rock & Dirt mode are
automatically canceled even if they
are selected.
●When the driving mode is
changed ( P.355)
●When the engine switch is turned
off
■Driving in Mud & Sand or Rock
& Dirt mode
The following types of situations
may occur, but they are not mal- functions.
●Vibrations may be felt throughout
the vehicle or steering wheel
●Operating noise may be heard
from the engine compartment
■When an inspection at your
Toyota dealer is necessary
In the following situ ations, the sys-
tem may be malf unctioning. Have
the vehicle inspected by your
Toyota dealer immediately.
