WARNING
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the
steering lock in this circumstance may lead to an accident, resulting in
death or serious injury.
■ Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
press and hold the engine switch for more than 3 seconds, or press it briefly
3 times or more in succession. ( P. 429)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine switch off while driving will not cause loss of
steering or braking control, but the power assist to these systems will be
lost. This will make it more difficult to steer and brake, so you should pull
over and stop the vehicle as soon as it is safe to do so.

NOTICE
■To prevent battery discharge
● Do not leave the engine switch in ACCESSORY or IGNITION ON mode
for long periods of time without the engine running.
● If the smart entry & start system indicator (green) is illuminated, the engine
switch is not off. When exiting the vehicle, always check that the engine
switch is off.
● On vehicles with a Multidrive, do not stop the engine when the shift lever is
in a position other than P. If the engine is stopped in another shift lever
position, the engine switch will not be turned off but instead be turned to
ACCESSORY mode. If the vehicle is left in ACCESSORY mode, battery
discharge may occur.
■ When starting the engine
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional immediately.
■ Symptoms indicating a malfunction with the engine switch
If the engine switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional immediately.

The gear step changes once
every time the shift lever or paddle
shift switch is operated.
The selected gear step, from 1 to
7, will be displayed in the multi-
information display.
However, even when in the M position, the gear steps will be automat-
ically changed if the engine speed is too high, or too low.
■Gear step functions
● You can choose from 7 levels of engine braking force.
● A lower gear step will provide greater engine braking force than a
higher gear step, and the engine speed will also increase.

in one gear step
● When the “+” paddle shift switch is held down for a period of time
■ When driving with the cruise control activated (if equipped)
Even when performing the following actions with the intent of enabling engine
braking, engine braking will not activate because cruise control will not be
canceled.

■ When the vehicle comes to a stop with the shift lever in the M position
● The transmission will automatically downshift to M1 once the vehicle is
stopped.
● After a stop, the vehicle will start off in M1.
● When the vehicle is stopped, the transmission is set at M1.
■ 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 switch is in the
“ON” position 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 brake pedal, there may
be a problem with the shift lock system (a system to prevent accidental oper-
ation of the shift lever). Have the vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional imme-
diately.
The following steps may be used as an emergency measure to ensure that
the shift lever can be shifted.
Releasing the shift lock:
Set the parking brake.
Turn the engine switch to the LOCK position (vehicles without a
smart entry & start system) or ACCESSORY mode (vehicles with a
smart entry & start system).
Depress the brake pedal.
Pry the cover up with a flathead
screwdriver or equivalent tool.
To prevent damage to the cover,
wrap the tip of the screwdriver with
a rag.

Press the shift lock override
button.
The shift lever can be shifted while
the button is pressed.
■ If the “M” indicator flashes or a buzzer beeps after shifting the shift lever
to M
This may indicate a malfunction in the Multidrive system. Have the vehicle
inspected by any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional immediately.
(In this situation, the transmission will operate in the same manner as when
the shift lever is in D.)
■ Downshift restriction warning buzzer (vehicles with a 7-speed sport
sequential shiftmatic mode)
To help ensure safety and driving performance, downshifting operation may
sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever or paddle shift switches are operated. (A
buzzer will sound twice.)

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 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 leading to an accident which may
result in death or serious injury.
