2064-1. Before driving
IS300h_EE(OM53B95E)
Your vehicle will handle differently when towing a trailer. In order to
avoid accident, death or serious injury, keep the following in mind when
towing:
Checking connections between trailer and lights
Stop the vehicle and check the operation of the connection between the
trailer and lights after driving for a brief period as well as before start-
ing off.
Practicing driving with a coupled trailer
Get the feel for turning, stopping and reversing with the trailer cou-
pled by practicing in an area with no or light traffic.
When reversing with a coupled trailer, hold the section of the steer-
ing wheel nearest to you and rotate clockwise to turn the trailer left
or counterclockwise to turn it right. Always rotate a little at a time to
prevent steering error. Have someone guide you when reversing to
lessen the risk of an accident.
Increasing vehicle-to-vehicle distance
At a speed of 10 km/h (6 mph), the distance to the vehicle running
ahead of you should be equivalent to or greater than the combined
length of your vehicle and trailer. Avoid sudden braking that may cause
skidding. Otherwise, the vehicle may spin out of control. This is espe-
cially true when driving on wet or slippery road surfaces.
Sudden acceleration/steering input/cornering
Executing sharp turns when towing may result in the trailer colliding
with your vehicle. Decelerate well in advance when approaching turns
and take them slowly and carefully to avoid sudden braking.
Important points regarding turning
The wheels of the trailer will travel closer to the inside of the curve
than the wheels of the vehicle. To make allowance for this, take the
turns wider than you would normally do.

and the parking brake is released. Daytime running lights are not designed for
use at night.
Headlight control sensor
Automatic light off system
When the light switch is in or : The headlights and front fog lights turn

Follow me home system
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detect-
ing the level of ambient light and may cause
the automatic headlight system to malfunc-
tion.

Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCESSORY
mode and the driver’s door is opened while the lights are turned on.
Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of
passengers and the loading condition of the vehicle to ensure that the headlights
do not interfere with other road users.
Operation guide display (vehicles with rain-sensing windshield wipers only)
When the headlight switch is operated to and from the “AUTO” position, the cur-
rent status is displayed on the meters for a few seconds to show that AUTO mode
is activated/deactivated. (P. 1 1 9 )
Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: P. 581)
NOTICE
To prevent 12-volt battery discharge
Do not leave the lights on longer than necessary when the hybrid system is off.

brightness of streetlights, the lights of oncoming and preceding vehicles,
etc., and automatically turns the high beam on or off as necessary.

ically turned off:
Vehicle speed drops below approximately 30 km/h (19 mph).
The area ahead of the vehicle is not dark.
Oncoming or preceding vehicles have headlights or tail lights turned
on.
There are many streetlights on the road ahead.

The Automatic High Beam can be operated when
The power switch is in ON mode.
Camera sensor detection information
High beam may not be automatically turned off in the following situations:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle
• When oncoming or preceding vehicles are hidden from sight due to repeated
curves, road dividers or roadside trees
High beam may be turned off if an oncoming vehicle that is using fog lights
without using the headlights is detected.
House lights, street lights, red traffic signals, and illuminated billboards or signs
may cause the high beam to turn off.
The following factors may affect the amount of time taken to turn high beam on
or off:
• The brightness of headlights, fog lights, and tail lights of oncoming and pre-
ceding vehicles
• The movement and direction of oncoming and preceding vehicles
• When an oncoming or preceding vehicle only has operational lights on one
side
• When an oncoming or preceding vehicle is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface etc.)
• The number of passengers and amount of luggage
High beam may be turned on or off when unexpected by the driver.
Small vehicles, such as bicycles, may not be detected.
In the situations below, the system may not be able to correctly detect the sur-
rounding brightness levels, and may flash or expose nearby pedestrians to the
high beam. Therefore, you should consider turning the high beams on or off
manually rather than relying on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• Surrounding brightness levels are equal to those of headlights, tail lights or
fog lights.
• Vehicles ahead have headlights or tail lights that are either switched off,
dirty, changing color, or have improperly adjusted aim.
• When driving through an area of intermittently changing brightness and
darkness.
• When frequently and repeatedly driving ascending/descending roads, or
roads with rough, bumpy or uneven surfaces (such as stone-paved roads,
gravel tracks etc.).
• When frequently and repeatedly taking curves or driving on a winding road.
• There is a highly reflective object ahead of the vehicle, such as a sign or a
mirror.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or titling, due to a flat tire, a trailer being towed etc.
• The driver believes that the high beam may be causing problems or distress
to other drivers or pedestrians nearby.
