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)

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.

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
● The parking brake is engaged
● 2 seconds at maximum elapsed after the brake pedal is released
