nThe meters and display illuminate when
The engine switch is in the “ON” position.
n Outside temperature display
lIn the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change.
• When stopped, or driving at low speeds (less than 9 mph [15 km/h])
• When the outside temperature has changed suddenly (at the entrance/
exit of a garage, tunnel, etc.)
l If “  ” is displayed continuously, the system may be malfunctioning. Take
your vehicle to your Scion dealer.
NOTICE
n To prevent damage to the engine and its components
lDo not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
l The engine may be overheating if the engine coolant temperature gauge
enters the red zone. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (P. 288)

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
nWhen driving the vehicle
lDo not drive if you are unfamiliar with the location of the brake and ac\
cel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a diffi- culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the
vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
l Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot
parts may cause a fire if there is any flammable material nearby.
l During normal driving, do not turn off the engine. 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.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 253
l Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 131, 135)
l Do not adjust the display, the positions of the steering wheel, the seat, or
the inside or outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
l Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.
l Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph ( 140 km/h) unless your vehicle has high-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on y our vehicle are high-speed capability
tires or not before driving at such speeds.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
nIf you hear a squealing or scraping noise (brake pad wear limit indica-
tors)
Have the brake pads checked and replaced by your Scion dealer as soon
as possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.
n When the vehicle is stopped
lDo not race the engine.
If the vehicle is in any gear other than P (continuously variable transmis-
sion) or N, the vehicle may accelerate suddenly and unexpectedly, caus-
ing an accident.
l Vehicles with a continuously variable transmission: In order to prevent
accidents due to the vehicle rolling away, always keep depressing the
brake pedal while the engine is running, and apply the parking brake as
necessary.
l If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
l Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combusti\
ble
material is nearby.
n When the vehicle is parked
lDo not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a
fire.
• The temperature inside the vehicle may cause the plastic lenses and
plastic material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.

1164-1. Before driving
Scion iM_U (12J49U)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
nWhen the vehicle is parked
lDo not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when
luggage is loaded or the seat is adjusted, causing a fire.
l Do not attach adhesive discs to the windshield or windows. Do not place
containers such as air fresheners on the instrument panel or dashboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehi-
cle.
l Do not leave a door or window open if the curved glass is coated with a
metallized film such as a silver-colored one. Reflected sunlight may cause
the glass to act as a lens, causing a fire.
l Vehicles with a continuously variable transmission: Always apply the park-
ing brake, shift the shift lever to P, stop the engine and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
Vehicles with a manual transmission: Always apply the parking brake,
stop the engine and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
l Do not touch the exhaust pipes while the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
n 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
ventilated area, exhaust gases may collect and enter the vehicle, leading to
death or a serious health hazard.

1304-2. Driving procedures
Scion iM_U (12J49U)
NOTICE
nTo prevent battery discharge
Do not leave the engine switch in the “ACC” or “ON” position for long peri-
ods of time without the engine running.
n When starting the engine
lDo not crank the engine for more than 30 seconds at a time. This may
overheat the starter and wiring system.
l Do not race a cold engine.
l If the engine becomes difficult to star t or stalls frequently, have your vehi-
cle checked by your Scion dealer immediately.

1584-5. Using the driving support systems
Scion iM_U (12J49U)
nTurning off both TRAC and VSC systems
To turn the TRAC and VSC systems off, press and hold for more than 3
seconds while the vehicle is stopped.
The VSC OFF indicator light will come on and the “Traction Control Turned
Off” will be shown on the multi-information display.
Press again to turn the systems back on.
n When the message is displayed on th e multi-information display show-
ing that TRAC has been disable d even if has not been pressed
TRAC and hill-start assist control cannot be operated. Contact your Scion
dealer.
n Sounds and vibrations caused by th e ABS, brake assist, TRAC and VSC
systems
l A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate
that a malfunction has occurred in any of these systems.
l Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
n EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
n Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
l When the engine switch is turned to the “LOCK” position
l If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
n Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the engine off. The
EPS system should return to normal within 10 minutes.
