*1: To improve fuel efficiency and reduce noises, set the shift le ver in the D
position for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of the possible
gear ranges, controls engine braking forces, and prevents unnec essary
upshifting.

Driving
To enter S mode, shift the shift lever to S. Shift ranges can be selected
by operating the shift lever, allowing you to drive in the shif t range of
your choosing. The shift range can be selected by the shift lev er.
Upshifting
Downshifting
The selected shift range, from 1 to 6, will be displayed in the meter.
The initial shift range in S mode is set automatically to 5 or 4 accord-
ing to vehicle speed. However, the initial shift range may be s et to 3 or
2 if the AI-SHIFT ( P. 229) has operated while the shift lever was in
the D position.

■Shift ranges and their functions
●Automatically selecting gears between 1 and 6 according to vehi -
cle speed and dri ving conditions.
● You can choose from 6 levels of accelerating force and engine
braking force.
● A lower shift range will provide greater accelerating force and
engine braking force than a higher shift range, and the engine
revolutions will also increase.
Use TOW/HAUL mode when pulling a trailer or hauling a heavy load.
Press the TOW/HAUL switch. T he indicator will come on.
Press the switch once more to cancel the mode.

■AI-SHIFT
AI-SHIFT automatically selects the suitable gear according to t he driver per-
formance and driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position.
(Shifting the shift lever to the S position cancels the functio n.)
■ When driving with cruise cont rol activated (if equipped)
Even when performing the following actions with the intent of e nabling engine
braking, engine braking will not activate while driving in S mo de and down-
shifting to 5 or 4 because cruise control will not be canceled. (P. 280 294)
■ Shift lock system
The shift lock system is a system to prevent accidental operation of the shift
lever in starting.
The shift lever can be shifted from P only when the engine swit ch is in ON
and the brake pedal is being depressed.
■ If the shift lever cannot be shifted from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brak e pedal, there may
be a problem with the shift lock system. Have the vehicle inspected by your
Toyota dealer immediately.
The following steps may be used as an emergency measure to ensu re that
the shift lever can be shifted.
Releasing the shift lock:
Set the parking brake.
Turn the engine switch to OFF.
Depress the brake pedal.

■If the “S” indicator does not come on even after shifting the s hift lever to
S
This may indicate a malfunction in the automatic transmission s ystem. Have
the vehicle inspected by your Toyota dealer, immediately.
(In this situation, the transmission will operate in the same m anner as when
the shift lever is in D.)
■ Downshifting restrictions warning buzzer (S mode)
To help ensure safety and driving performance, downshifting ope ration may
sometimes be restricted. In some circumstances, downshifting ma y not be
possible even when the shift lever is operated. (A buzzer will sound twice.)
■ Transmission protection function
If the tires spin continually when the vehicle becomes stuck in mud, dirt or
snow, the automatic transmission temperature may become too high and
cause damage.
To avoid the damaging the automatic transmission, the system may tempo-
rarily lock the gear in 1st.
If the automatic transmission temperature falls, the gear locki ng is canceled
and returns the automatic transmission to the normal operation.
WARNING
■ 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.
■ To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to se t the parking
brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of t he brake pedal
when the shift lock override button is pressed and the shift le ver is shifted
out of P, the vehicle may suddenly start, possibly leading to a n accident
resulting in death or serious injury.
