2017 TOYOTA COROLLA iM warning

1764-5. Using the driving support systems
COROLLA iM_U (OM12K64U)
When driving on roads with white (yellow) lines, this function alerts the
driver when the vehicle might depart from its lane.
The LDA system recognizes visi-
ble white (yellow) lines with the
front sensor on the upper portion
of the front windshield.
When the system determines that
the vehicle might depart from its
lane, a warning is displayed on
the multi-information display and
the warning buzzer sounds to
alert the driver.
When the warning buzzer sounds,
check the surrounding road situa-
tion and carefully operate the
steering wheel to move the vehicle
back to the center within the white
(yellow) lines.

WARNING
■Before using the LDA system
Do not rely solely upon the LDA system. LDA is not a system which auto-
matically drives the vehicle or reduces the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by always paying careful attention to the sur-
rounding conditions and operate the steering wheel to correct the path of
the vehicle. Also, make sure to take adequate breaks when fatigued, such
as from driving for a long period of time.
Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
■To avoid operating the LDA by mistake
When not using the LDA system, use the LDA switch to turn the system off.
■Preventing LDA system malfunctions and operations performed by
mistake
●Do not modify the headlights or place stickers, etc., on the surface of the
lights.
●Do not modify the suspension etc. If the suspension etc. needs to be
replaced, contact your Toyota dealer.
●Do not install or place anything on the hood or grille. Also, do not install a
grille guard (bull bars, kangaroo bar, etc.).
●If your windshield needs repairs, contact your Toyota dealer.

■Temporary cancellation of functions
When operation conditions are no longer met, a function may be temporarily
canceled. However, when the operation conditions are met again, operation
of the function is automatically restored.
■Lane departure alert function
The warning buzzer may be difficult to hear due to external noise, audio play-
back, etc.
■White (yellow) lines are only on one side of road
The LDA system will not operate for the side on which white (yellow) lines
could not be recognized.
■After the vehicle has been parked in the sun
The LDA system may not be available and a warning message may be dis-
played for a while after starting off. When the temperature in the cabin
decreases and the temperature around the front sensor (→P. 159) becomes
suitable for its operation, the system will begin to operate.
■If there are lane markers on only one side of the vehicle
The lane departure warning will not operate for the side on which lane mark-
ers could not be recognized.

improper tire pressure.
●The distance to the preceding vehicle is extremely short.

Doing so may result in loss of control and could cause an accident resulting
in death or serious injury.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those covered with rain, ice or snow
●On steep hills
Vehicle speed may exceed the set speed when driving down a steep hill.
●During emergency towing

WARNING
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
●The vehicle hydroplanes while driving at high speed on wet or slick roads.
■Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
●When driving on dirt, gravel or snow-covered roads
●When driving over bumps in the road
●When driving over roads with potholes or uneven surfaces
■TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■Hill- start assist control does not operate effectively when
●Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.
●Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■When the TRAC or VSC system is turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems help ensure vehicle stability and driving
force, do not turn the TRAC or VSC system off unless necessary.

WARNING
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

1934-7. Driving tips

Driving
COROLLA iM_U (OM12K64U)
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
●Park the vehicle and move the shift lever to P (continuously variable
transmission), 1 or R (manual transmission) without setting the park-
ing brake. The parking brake may freeze up, preventing it from
being released. If the vehicle is parked without setting the parking
brake, make sure to block the wheels.
Failure to do so may be dangerous because it may cause the vehi-
cle to move unexpectedly, possibly leading to an accident.
●Vehicles with a continuously variable transmission: If the vehicle is
parked without setting the parking brake, confirm that the shift lever
cannot be moved out of P
*.
*: The shift lever will be locked if it is attempted to be shifted from P to any
other position without depressing the brake pedal. If the shift lever can be
shifted from P, there may be a problem with the shift lock system. Have the
vehicle inspected by your Toyota dealer immediately.
Tire chains cannot be mounted.
Snow tires should be used instead.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the size specified.
●Maintain the recommended level of air pressure.
●Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
●Use snow tires on all, not just some wheels.
