■Temporary cancelation of the LKA system functions
If any of the following occurs, the LKA system functions will be temporarily
canceled. The functions will resume after the necessary operating conditions
have returned.
● The turn signal lever is operated.
● The steering wheel is turned as far as necessary to cause the vehicle to
change lanes.
● The brake pedal is depressed.
However, the lane keeping assist function will not resume even after the
brake pedal is released because depressing the brake pedal also can-
cels the dynamic radar cruise control. (Only lane departure warning func-
tion will resume.)
● The vehicle speed deviates from the operating range of the LKA system
functions.
● When the lane lines cannot be recognized while driving.
● The wiper operates continuously.
■ When the lane departure wa rning function is activated
The lane departure warning function will be temporarily canceled and will not
resume until a few seconds elapse after it is activated.

■Precautions for the Remote Air Conditioning System
●Do not use the system if people are in the vehicle.
• Even when the system is in use, the internal temperature may still
reach a high level due to features such as the automatic shut-off. Chil-
dren and pets left inside the vehicle may suffer heatstroke or dehydra-
tion, or could result in death or serious injury.
• The wipers can be operated during system operation. Children or pets left inside the vehicle may mistakenly operate these and cause an acci-
dent.
● Depending on the surrounding environment, signals from the wireless
switch may transmit further than expected. Pay appropriate attention to
the vehicle’s surroundings and use the switch only when necessary.
● Turn the wipers off. If the Remote Air Conditioning System operates while
the wiper switch is in the on position, the wipers may operate and objects
may get caught in the wiper blades.
● Do not operate the if the hood is open. The air conditioning may
operate unintentionally and objects may be drawn into the electrical cool-
ing fan.
