CAUTION
■
When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever
or depress the accelerator pedal, this could cause an accident or fire due to
engine overheating. Additionally, if the vehicle is parked in a poorly venti-
lated area, exhaust gases may collect and enter the vehicle, leading to
death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also the
parking brake may not securely hold the vehicle.
● If the power brake assist function does not operate, do not follow other
vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 individual hydraulic systems: If one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and braking distance will
increase.
If this happens, do not continue to drive the vehicle. Have your brakes
fixed immediately.
■ If the vehicle becomes stuck (AWD models)
Do not spin the wheels excessively when any of the tires is up in the air, or
the vehicle is stuck in sand or mud, etc. This may damage the driveline com-
ponents or unexpectedly propel the vehicle forward or backward, causing an
accident.

Engine (ignition) switch (vehicles with smar t key system)
Performing the following operations when carrying the electronic
key on your person starts the engine or changes “ENGINE START
STOP” switch modes.
■ Starting the engine
Check that the parking brake is set.
Check that the shift lever is set in P.
Firmly depress the brake pedal.
The “ENGINE START STOP” switch indicator will turn green. If
the indicator does not turn green, the engine cannot be started.
Press the “ENGINE START
STOP” switch.
The engine will crank until it
starts or for up to 30 seconds,
whichever is less.
Continue depressing the brake
pedal until the engine is com-
pletely started.
The engine can be started
from any “ENGINE START
STOP” switch mode.

NOTICE
■
To prevent battery discharge
● Do not leave the “ENGINE START STOP” switch in ACCESSORY or IGNI-
TION ON mode for long periods of time without the engine running.
● If the indicator on the “ENGINE START STOP” switch is illuminated, the
“ENGINE START STOP” switch is not off. When exiting the vehicle,
always check that the “ENGINE START STOP” switch is off.
● 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 START
STOP” 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 the engine
checked immediately.
■ Symptoms indicating a malfunctio n with the “ENGINE START STOP”
switch
If the “ENGINE START STOP” seems to be operating somewhat differently
than usual, such as the switch sticking slightly, there may be a malfunction.
Contact your Toyota dealer immediately.

Shift position purpose
*1: Shifting to the D position allows the system to select a gear suitable
for the driving conditions. Setting the shift lever to the D position is
recommended for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of thepossible gear ranges, controls engine braking forces, and prevents
unnecessary upshifting.

■
Shift ranges and their functions
●Automatically selecting gears between 1 and 6 according to
vehicle speed and driving conditi ons. But, the gear is limited
according to selected shift range.
● You can choose from 6 levels of engine braking force.
● A lower shift range will provide greater engine br aking force than
a higher shift range, and the engine speed will also increase.
■S mode
● When the shift range is 5 or lower, holding the shift lever toward “+” sets
the shift range to 6.
● To prevent excessive engine speed, a function was adopted that auto-
matically selects a higher shift range before the engine speed becomes
too high.
● To protect the automatic transaxle, a function is adopted that automati-
cally selects a higher shift range when the fluid temperature is high.
■ When driving with the cruise contro l or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to 5 or 4.
( P. 293, 298)
■ If the shift lever cannot be shifted from P
● P. 764
● Vehicles with AUTO ACCESS SEAT : If the AUTO ACCESS SEAT has
not been locked in place after being stowed, the shift lever cannot be
shifted from P.
For details, refer to “AUTO ACCESS SEAT OWNER’S MANUAL”.
