Toyota Corolla Cross: Before Starting Driving Adjustment
BEFORE STARTING DRIVING ADJUSTMENT
CAUTION / NOTICE / HINT
NOTICE:
When replacing the windshield glass of a vehicle equipped with a
forward recognition camera, make sure to use a Toyota genuine part. If a non-Toyota
genuine part is used, the forward recognition camera may not be able to be installed
due to a missing bracket. Also, the front camera system or automatic high beam system
may not operate properly due to a difference in the transmissivity or black ceramic
border.
HINT:
- Purpose of forward recognition camera optical axis learning:
- If the installation position or orientation of the forward recognition
camera is changed due to it being replaced with a new one or the
windshield glass sub-assembly being replaced or removed and installed,
it is necessary to perform forward recognition camera optical axis
learning for the forward recognition camera to learn the driving
direction of the vehicle and its horizontal axis in order for each
driving support system to operate correctly.

PROCEDURE
1. PERFORM DRIVING ADJUSTMENT
NOTICE:
- When performing the driving adjustment, obey all applicable traffic
laws.
- Select a road where the driving adjustment can be carried out safely.
(a) Driving adjustment concept
- Based on the observed movement in external imaging data (white
lines, buildings, etc.) captured by the forward recognition camera
while the vehicle is being driven, the vehicle driving direction
is calculated and stored within the camera, and in this way adjustment
is performed.
- The time required before adjustment is completed varies according
to the vehicle speed and external conditions.

(b) Driving conditions
- Perform the adjustment outside during daytime, on a sunny or cloudy
day.
- If preceding vehicles are present, they should be kept at a distance
of at least 20 m (66 ft.)
- Perform the adjustment mainly on a straight road without incline or
decline, with a dry and smooth road surface.
- Do not perform the adjustment when there is a possibility of the vehicle
slipping sideways such as on icy roads.
- Steer the vehicle straight without drifting or wobbling, and avoid sudden
acceleration or deceleration.
- Drive at a vehicle speed of 30 km/h (19 mph) or more.
After driving the vehicle with all conditions met for approximately
5 to 15 minutes cumulatively, the adjustment will be completed.
HINT:
- If the adjustment does not complete within a total cumulative time of
15 minutes when the vehicle is driven with all conditions met, perform the
adjustment on another route.
- If the adjustment does not complete within a total cumulative time of
30 minutes when the vehicle is driven with all conditions met, perform the
adjustment using target recognition.
- If the vehicle is driven unsteadily or many lane changes are performed,
the time taken for adjustment to complete may increase.
- When a difficulty judgment without waiting for 15 minutes continues,
change a run route.
(c) Road environment
HINT:
When driving on a bumpy or unpaved road, making frequent accelerations
and decelerations, etc., the camera condition may be unstable, which may cause adjustment
to take a long time.
- Road environments conducive to adjustment
*a |
Roads with continuous white lines |
*b |
Roads with objects such as buildings or utility
poles |
- Road environments which hinder adjustment
*a |
Roads with scenery that does not change |
*b |
Backlit or high-glare environments |
*c |
When surrounded by moving vehicles |
- |
- |
(d) Axis adjustment difficult judgement.
- The system monitors the progress of the adjustment, and if it is determined
that the vehicle is traveling in a road environment where adjustment is
difficult, the buzzer sounds twice to notify the user.
- When it is determined that the vehicle is driving in a road environment
where adjustment is difficult, the buzzer sounds at 20-second intervals.
- If it is determined that the vehicle is driving in a road environment
where adjustment is not difficult, the buzzer does not sound.
HINT:
When performing adjustment with the GTS connected to the vehicle,
"Adjusting (Slow)" is displayed on the progress confirmation screen when it is determined
that the vehicle is driving in a road environment where adjustment is difficult.
