WARNING
■The display at low temperatures
Allow the interior of the vehicle to warm up before using the d isplay. At
extremely low temperatures, the display monitor may respond slo wly, and
display changes may be delayed.
For example, there is a lag between the driver’s shifting and t he new gear
number appearing on the display. This lag could cause the drive r to down-
shift again, causing rapid and excessive engine braking and pos sibly an
accident resulting in death or injury.
■ Cautions during setting up the display
As the engine needs to be running during setting up the display , ensure that
the vehicle is parked in a place with adequate ventilation. In a closed area
such as a garage, exhaust gases including harmful carbon monoxi de (CO)
may collect and enter the vehicle. This may lead to death or a serious
health hazard.
NOTICE
■ To prevent damage to the engine and its components
● Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the engine coolant temperature gauge
are in the red zone. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. ( P. 531)

1564-1. Before driving
COROLLA_TMMMS_TMMC_U
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
● Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the b rake
pedal will result in sudden acceleration that may lead to an ac cident.
• 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 t he
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.
● Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. Thes e hot
parts may cause a fire if there is any flammable material nearb y.
● During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking contro l, but the
power assist to these systems will be lost. This will make it m ore difficult to
steer and brake, so you should pull over and stop the vehicle a s soon as it
is safe to do so.
However, in the event of an emergency, such as if it becomes im possible
to stop the vehicle in the normal way: P. 471
● 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. 181, 184, 189)
● 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.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.
● Do not drive in excess of the speed limit. Even if the legal sp eed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicl e has high-
speed capability tires. Driving over 85 mph (140 km/h) may resu lt in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed c apability
tires or not before driving at such speeds.

1584-1. Before driving
COROLLA_TMMMS_TMMC_U
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■If you hear a squealing or scrap ing noise (brake pad wear limit indica-
tors)
Have the brake pads checked and replaced by your Toyota 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.
■ When the vehicle is stopped
● Do not race the engine.
If the vehicle is in any gear other than P (continuously variab le transmis-
sion) or N, the vehicle may accelerate suddenly and unexpectedl y, caus-
ing an accident.
● Vehicles with a continuously variable transmission: In order to prevent
accidents due to the vehicle rolling away, always keep depressi ng the
brake pedal while the engine is running, and apply the parking brake as
necessary.
● If the vehicle is stopped on an incline, in order to prevent ac cidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped m ay cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.
■ When the vehicle is parked
● Do not leave glasses, cigarette lighters, spray cans, or soft d rink 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 le ad 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 ov er the
interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is parked
● Do 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 acci dentally when
luggage is loaded or the seat is adjusted, causing a fire.
● Do not attach adhesive discs to the windshield or windows. Do n ot place
containers such as air fresheners on the instrument panel or da shboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehi-
cle.
● Do not leave a door or window open if the curved glass is coate d with a
metallized film such as a silver-colored one. Reflected sunligh t may cause
the glass to act as a lens, causing a fire.
● Vehicles with a continuously variable transmission: Always appl y 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 .
If the vehicle is parked with the shift lever in P but the park ing brake is not
set, the vehicle may start to move, possibly leading to an acci dent.
Vehicles with a manual transmission: Always apply the parking b rake,
stop the engine and lock the vehicle.
Do not leave the vehicle unattended while the engine is running .
● Do not touch the exhaust pipes while the engine is running or i mmediately
after turning the engine off.
Doing so may cause burns.
■ 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 acc ident or fire
due to engine overheating. Additionally, if the vehicle is park ed in a poorly
ventilated area, exhaust gases may collect and enter the vehicl e, leading to
death or a serious health hazard.

2604-5. Using the driving support systems
COROLLA_TMMMS_TMMC_U■
Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the s ystem from
overheating when there is frequent steering input over an exten ded period of
time. The steering wheel may feel heavy as a result. Should thi s 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.
■ Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assi st control will
operate:
● Vehicles with a continuously variable transmission: The shift l ever is in a
position other than P or N (when starting off forward/backward on an upward
incline)
● Vehicles with a manual transmission: The shift lever is in a po sition other
than R when starting off forward on an upward incline, or the s hift lever is in
R when starting off backward on an upward incline.
● The vehicle is stopped
● The accelerator pedal is not depressed
● The parking brake is not engaged
■ Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the follo wing situations:
● Vehicles with a continuously variable transmission: The shift l ever is shifted
to P or N
● Vehicles with a manual transmission: The shift lever is shifted to R when
starting off forward on an upward incline, or the shift lever i s shifted to other
than R when starting off backward on an upward incline.
● The accelerator pedal is depressed
