CAUTION

■

When braking

●

When the brakes are wet, drive more cautiously. 
Braking distance increases when the brakes are wet, and 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.
Have your brakes fixed immediately.

●

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 the braking distance will
increase.
Have your brakes fixed immediately.

NOTICE

■

When driving the vehicle (vehicles with an automatic transmission)

●

Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain driving torque.

●

Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.

■

When driving the vehicle (vehicles with a manual transmission)

●

Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain driving torque.

●

Do not shift gears unless the clutch pedal is fully depressed. After shifting,
do not release the clutch pedal abruptly. Doing so may damage the clutch,
transmission and gears.

●

Observe the following to prevent the clutch from being damaged.

• Do not rest your foot on the clutch pedal while driving.

Doing so may cause clutch trouble.

• Do not use any gear other than the 1st gear when starting off and mov-

ing forward.
Doing so may damage the clutch.

• Do not use the clutch to hold the vehicle when stopping on an uphill

grade.
Doing so may damage the clutch.

●

Do not shift the shift lever to R when the vehicle is still moving. Doing so
may damage the clutch, transmission and gears.

NOTICE

■

When parking the vehicle (vehicles with an automatic transmission)

Always shift the shift lever to P. Failure to do so may cause the vehicle to
move or the vehicle may accelerate suddenly if the accelerator pedal is acci-
dentally depressed.

■

Avoiding damage to vehicle parts

●

Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time. 
Doing so may damage the power steering motor.

●

When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.

■

If you get a flat tire while driving

A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehicle.

●

It may be difficult to control your vehicle.

●

The vehicle will make abnormal sounds or vibrations.

●

The vehicle will lean abnormally.

NOTICE

■

When encountering flooded roads

Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:

●

Engine stalling

●

Short in electrical components 

●

Engine damage caused by water immersion

In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Scion dealer check the following:

●

Brake function

●

Changes in quantity and quality of engine oil, transaxle fluid, etc.

●

Lubricant condition for the bearings and suspension joints (where possi-
ble) and the function of all joints, bearings, etc.

CAUTION

■

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.

Auto power off function

Vehicles with an automatic transmission
If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNI-
TION ON mode (the engine is not running) for more than an hour with the
shift lever in P, the “ENGINE START STOP” switch will automatically turn off.
However, this function cannot entirely prevent battery discharge. Do not
leave the vehicle with the “ENGINE START STOP” switch in ACCESSORY
or IGNITION ON mode for long periods of time when the engine is not run-
ning.

Vehicles with a manual transmission
If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNI-
TION ON mode (the engine is not running) for more than an hour, the
“ENGINE START STOP” switch will automatically turn off. However, this
function cannot entirely prevent battery discharge. Do not leave the vehicle
with the “ENGINE START STOP” switch in ACCESSORY or IGNITION ON
mode for long periods of time when the engine is not running.

■

Operation of the “ENGINE START STOP” switch

When operating the “ENGINE START STOP” switch, one short, firm press is
enough. If the switch is pressed improperly, the engine may not start or the
“ENGINE START STOP” switch mode may not change. It is not necessary to
press and hold the switch.

Steering lock

After turning the “ENGINE START STOP” switch off and opening and closing
the doors, the steering wheel will be locked due to the steering lock function.

Steering lock motor overheating prevention

To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning.

When the “ENGINE START STOP” switch indicator flashes in amber

The system may be malfunctioning. Have the vehicle inspected by your
Scion dealer immediately.

CAUTION

■

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 the vehicle begins to slide due to engine failure or other circumstances, 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 acci-
dent, 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 START STOP” switch for more than 2 seconds,
or press it briefly 3 times or more in succession.
However, do not touch the “ENGINE START STOP” switch while driving
except in an emergency. Turning the engine 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.
