nThe meters and display illuminate when
Vehicles without a smart key system
The engine switch is in the “ON” position.
Vehicles with a smart key system
The engine switch is in IGNITION ON mode.
n When disconnecting and reco nnecting battery terminals
The following information data will be reset:
l Average fuel consumption
l Driving range
l Average vehicle speed
CAUTION
n The display at low temperatures
Allow the interior of the vehicle to warm up before using the display. At
extremely low temperatures, the display monitor may respond slowly, and
display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This lag could cause the driver to down-
shift again, causing rapid and excessive engine braking and possibly an
accident resulting in death or injury.
n 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 monoxide (CO)
may collect and enter the vehicle. This may lead to death or a serious
health hazard.
NOTICE
nTo 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 high engine coolant temperature
warning light comes on. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (P. 543)

1504-1. Before driving
COROLLA_TMMMS_TMMC_U (OM12J84U)
CAUTION
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. 489
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. 176, 178, 180, 184)
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.

1524-1. Before driving
COROLLA_TMMMS_TMMC_U (OM12J84U)
CAUTION
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 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.
n When the vehicle is stopped
lDo not race the engine.
If the vehicle is in any gear other than P (automatic transmission or contin-
uously variable transmission) or N, the vehicle may accelerate suddenly
and unexpectedly, causing an accident.
l Except vehicles with a manual 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.

CAUTION
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 an automatic transmission or continuously variable transmis-
sion: Always apply the parking 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.

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 Toyota dealer immediately.
