Q Transmission protection function
If the tires spin continually when the vehicle becomes stuck in mud, dirt or
snow, or if the accelerator pedal is depressed and released repeatedly while
driving, the automatic transmission temperature may become too high and
the automatic transmission may be damaged.
To avoid damaging the automatic transmission, the system may temporarily
lock the gear.
If the automatic transmission temperature falls, the gear locking is canceled
and the automatic transmission is returned to the normal operation.
Q If the warning message is displayed
When the warning message goes out, the vehicle can be driven again.
If the warning message does not go out after waiting a while, have your vehi-
cle inspected by any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer.
Q AI-SHIFT
The AI-SHIFT automatically selects the suitable gear according to driver per-
formance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in D. (Shifting the
shift lever to S cancels the function.)
If the automatic transmission fluid tem-
perature warning message is displayed
while driving, make sure to return to D
position driving and reduce speed by eas-
ing off the accelerator pedal. Stop the
vehicle in a safe place, shift the shift lever
to P and let the engine idle until the warn-
ing message goes out.
WARNING
Q When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
Q To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to set the parking
brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of the brake pedal
when the shift lock override button is pressed and the shift lever is shifted
out of P, the vehicle may suddenly start, possibly leading to an accident
resulting in death or serious injury.

iMT detects clutch pedal and shift lever operations performed by the
driver. When the shift position is changed, iMT judges the optimal
engine speed and performs the appropriate control to help the driver
to change the shift position smoothly.
Press the “iMT” switch.
The “iMT” indicator will come on.
Press the switch again to cancel
iMT.

Q Operation of the air conditioning system in Eco drive mode (vehicles
with automatic air conditioning system)
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency ( P. 446). To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
Q Deactivation of the driving mode
O Eco drive mode will not be canceled until the “ECO” button is pressed, even
if the engine is turned off after driving in Eco drive mode.
O Power mode will be canceled if the engine is turned off after driving in power
mode.
O Driving mode will be canceled if the transfer mode is shifted to L4 while the
driving mode is in other than normal mode. (if equipped)
Q Reverse warning buzzer (6-speed transmission)
A buzzer will sound to alert the driver if the shift lever is shifted to the R posi-
tion.
Q Operation of iMT
O When the clutch pedal is depressed and the shift lever is moved to a posi-
tion, iMT controls the engine speed to be optimal for changing the shift posi-
tion. However, iMT stops operating before the shift position is changed if the
clutch pedal is not released for a while, and the engine speed cannot be
controlled. To operate iMT again, depress the clutch pedal and operate the
shift lever.
O The engine speed may be increased when the clutch pedal is depressed,
however, this does not indicate a malfunction.
Q When iMT does not operate
In the following situations, iMT may not operate. However, this does not indi-
cate a malfunction.
O The shift lever is not operated for a long time after the clutch pedal is
depressed.
O The vehicle moves for a while after the shift lever is shifted to N and the
clutch pedal is released, and then the clutch pedal is depressed and the
shift lever is moved to a position.
O The clutch pedal is not completely released and depressed again.
O The clutch pedal is not fully depressed.
Q If the warning message for iMT is shown on the multi-information dis-
play
iMT may be malfunctioning and the function is disabled. Have the vehicle
inspected at any authorized Toyota reta iler or Toyota authorized repairer, or
any reliable repairer as soon as possible.

WARNING
QLimitations of the iMT
iMT is not a system that prevents shift lever operation error or engine over-
revving. Depending on the situation, iMT may not operate normally and the
shift position may not be changed smoothly. Overly relying on iMT may
cause an unexpected accident.
NOTICE
Q To prevent damage to the vehicle
O Shift the shift lever to R only when the vehicle is stationary.
O Do not rest your hand on or hold the shift lever any time other than when
shifting.
O In order not to cause the engine to overrev, make sure to only shift gears
sequentially.
O Do not release the clutch pedal suddenly, as doing so may cause damage
to the clutch or transmission.
