WARNING
■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.
■ 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
■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)

Driving

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 accidentally when
luggage is loaded or the seat is adjusted, causing a fire.
● 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.
● 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.
● 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.
If the vehicle is parked with the shift lever in P but the parking brake is not
set, the vehicle may start to move, possibly leading to an accident.
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.
● Do not touch the exhaust pipes while the engine is running or immediately
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 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.

engine switch again automatically cancels the steering lock.
■ When the steering lock cannot be released
Vehicles with a manual transmission: Press the engine switch while turning
the steering wheel left and right.
■ Steering lock motor o verheating 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. “Steering Lock Active” will be displayed on
the multi-information display.

NOTICE
■Before driving
Fully release the parking brake.
Driving the vehicle with the parking brake set will lead to brake components
overheating, which may affect braking performance and increase brake
wear.

2604-5. Using the driving support systems
COROLLA_TMMMS_TMMC_U (01999-02509)■
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 of\
f. 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 assist control will
operate:
● Vehicles with a continuously variable transmission: The shift lever 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 position other
than R when starting off forward on an upward incline, or the shift 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 following situations:
● Vehicles with a continuously variable transmission: The shift lever 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 is 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

When trouble arises
COROLLA_TMMMS_TMMC_U (01999-02509)
●The engine coolant temperature gauge ( →P. 77, 86) enters the red
zone or a loss of power is experienced.
● Steam comes out from under the hood.
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled
