■Daytime running light system (if equipped)
●To make your vehicle more visible to other drivers, the daytime running
lights turn on automatically whenever the engine is started and the parking
brake is released. Daytime running lights are not designed for use at night.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor (vehicl es with automatic headlight system)
■ Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30 sec-
onds after a door is opened and closed if the engine switch is turned to the
“ACC” or “LOCK” position. (The lights turn off immediately if the button
on the key is pressed after all the doors are locked.)
● When only the tail lights come on: The tail lights turn off automatically if the
engine switch is tuned to the “ACC” or “LOCK” position and the driver’s door
is opened.

(Customizable features: P. 534)
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
NOTICE
■
To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not
running.

2394-5. Using the driving support systems
4
Driving
While driving 20 - 25 mph [35 - 40 km/h], fully apply the manual
TRAILER BRAKE OUTPUT
slider.
Adjust the gain settin g, using the GAIN (+/-) selection buttons, to
either increase or decrease to just below the point of trailer wheel
lock-up.
For confirmation, repeat steps 6 and 7 until desired gain setting is
reached (just below point of trailer wheel lock-up).
■ When using the trailer brake control system
Please turn off the intuitive parking assist while towing a trailer. If left on,
sonar sensors will detect the trailer being towed.
■ When setting the gain
Wheel lock-up occurs when the trailer wheel squeals or tire smoke occurs.
Trailer wheels may not lock-up while driving heavily loaded trailer. During this
case, adjust the Trailer gain to the highest allowable setting for the towing
condition.
■ When disconnecting and reco nnecting battery terminals
The gain setting data will be reset.
CAUTION
■ Trailer brake type setting
It is the responsibility of the driver to make sure the trailer brakes are func-
tioning normally and adjusted appropriately. Failure to check and maintain
trailer brakes may result in loss of vehicle control, crash, or serious injury.
Trailer brake control system will work with most electric and electric-over-
hydraulic trailer braking systems up to 3 axles (24A output to trailer brakes).
Please be sure to test compatibility with the system at low speeds and in a
safe area.
Some electric-over-hydraulic trailer brakes will take some minimum output
to activate. Trailer brake control system will not work with trailer hydraulic
surge brakes.
■ When driving on slippery road surfaces
When stopping with ABS activated, output to the trailer might be reduced\
in
order to reduce the likelihood of trailer to sway or trailer wheels to lock. The
trailer is not equipped with ABS. Drive safely on slippery road surfaces.
