■When the four-wheel drive control switch can be operated
●The engine switch is in IGNITION ON mode.
●The shift lever is in the N position.
●The vehicle is stopped completely.
■The low speed four-wheel drive indicator
●The indicator blinks while sw
itching between H4 and L4.
●If the low speed four-wheel drive indicator continues to blink when you operate the
four-wheel drive control switch to the H4 or L4 position, stop the vehicle completely,
shift the shift lever securely into N and then operate the switch again.
●If the shift lever is moved before the low speed four-wheel drive indicator turns on/off,
the transfer mode may not be shifted completely. The transfer mode disengages both
the front and rear drive shafts from the powertrain and allows the vehicle to move
regardless of the shift position. (At this time , the indicator blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the shift lever is in P. You or someone else
could be seriously injured. You must comple te the shifting of the transfer mode and
confirm that the indicator has turned off (H4) or turned on (L4).
●If the engine coolant temperature is too low, the four-wheel drive control system may
not be able to shift. When the engine is warmer operate the switch again.
If the indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive system.

Vehicles without Multi-terrain Select:
VSC is automatically turned off. (T he VSC OFF indicator will come on.)
Vehicles with Multi-terrain Select:
VSC and TRAC/Active TRAC are automatically turned off. (The VSC OFF indicator will
come on and the “TRAC OFF” will be sh own on the multi-information display.)

●If the center differential lock indicator b links and the buzzer sounds when the center
differential is locked, stop the slipping or spinning and push the switch again.
If the indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive system.

■Operating tips
The system will operate when the shift lever is in a position other than P, however to make
effective use of the system it is recommended that the shift lever be shifted to 2 or 1 range
of S mode.
■If the four-wheel drive
control switch is in H4

■When the downhill assist control system is operated continuously
This may cause the brake actuator to overheat. In this case, the downhill assist control
system will stop operating, a buzzer will sound and the downhill assist control system
indicator will start flashing, and the “TRAC OF F” will be shown on the multi-information
display. Refrain from using th e system until the downhill assi st control system indicator
stays on and the message goes of f. (The vehicle can be driven normally during this time.)
■Sounds and vibrations caused by the downhill assist control system
●A sound may be heard from the engine compartment when the engine is started or just
after the vehicle begins to move. This soun d does not indicate that a malfunction has
occurred in downhill assist control system.
●Either of the following conditions may occur when the do wnhill assist control system is
operating. None of these are indicators that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard afte r the vehicle comes to a stop.

is pressed.
●The slip indicator comes on.
In the above cases, have your vehicle checked by your Lexus dealer.

tions, and drive safely.

Interior features
■Registering air conditioning settings to electronic keys
●Unlocking the vehicle using an electronic key and turning the engine switch to
IGNITION ON mode will recall that key’s registered air conditioning settings.
●When the engine switch is turned off, the current air conditioning settings will automat-
ically be registered to the electronic key that was used to unlock the vehicle.
The system may not operate correctly if more than one electronic key is in the vicinity or
if the smart access system with push-button start is used to unlock a passenger door.
Settings for the electronic key and th e corresponding door can be changed.
Contact your Lexus dealer.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the ambi-
ent conditions.
Therefore, the fan may stop for a while until wa rm or cool air is ready to flow immediately
after the “AUTO” button is pressed.
■When the outside temperature exceeds 75 °F (24 °C) and the air conditioning system
is on
●In order to reduce the air co nditioning power consumption, the air conditioning system
may switch to recirculated air mode automatically.
This may also reduce fuel consumption.
●Recirculated air mode is selected as a defaul t mode when the engine switch is turned to
IGNITION ON mode.
●It is possible to switch to outside air mode at any time by pressing or
.
■Fogging up of the windows
●The windows will easily fog up when the humidi ty in the vehicle is high. Touching “A/C”
on will dehumidify the air from the outl ets and defog the windshield effectively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recircu-
lated air mode button to the recirculated air mode. This is effective in preventing out-
side air from enteri ng the vehicle interior. During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automa tically switch depending on the tempera-
ture setting or the inside temperature.
