Your vehicle will handle differently when towing a trailer. In order to avoid acci-
dent, 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 starting off.
■Practicing driving with a coupled trailer
●Get the feel for turning, stopping an d reversing with the trailer coupled by
practicing in an area with no or light traffic.
●When reversing with a coupled trailer, hold the section of the steering
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 vehi-
cle and trailer. Avoid sudden braking that may cause skidding. Otherwise, the
vehicle may spin out of control. This is especially 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 clos er 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.

WARNING
■When driving on slippery road surfaces
Be careful of downshifting and sudden acceler ation, as this could result in the vehicle skidding to the side or spinning.
■Gear Shift Indicator display (if equipped)
For safety, the driver should not look only at the display. Refer to the display when it is safe to do so while considering actual traffic and road conditions.
Failure to do so may lead to an accident.
■To prevent an accident wh en releasing the shift lock
Before pressing the shift lock override butt on, make sure to set the parking brake and
depress the brake pedal. If the accelerator pedal is accidentally depressed instead of the brake pedal when theshift lock override button is pressed and the shift lever is shifted out of P, the vehicle
may suddenly start, possibly leading to an accident resulting in death or serious injury.

●Adjusts the brightness and illuminated area of the high beams according to
the vehicle speed.
●Adjusts the intensity of the high beams, while driving on a curve, so that the
area in the direction that the vehicle is turning will be illuminated more brightly
than other areas.
●Operates the shaded high beams so
that the area around vehicles ahead
is partially not illuminated while all
other areas continue to be illumi-
nated with the high beams.
The shaded high beams help optimize forward visibility while reducing the daz-
zling effect on the drivers of vehicles ahead.
●Adjusts the distance that the low beams are projected according to the dis-
tance to a preceding vehicle.
AHS (Adaptive High-beam System)
: If equipped
The Adaptive High-beam System uses a camera sensor located behind the
upper portion of the windshield to assess the brightness of the lights of vehi-
cles ahead, streetlights, etc., and automatically controls the headlight light
distribution as necessary.
WARNING
■Limitations of the Adaptive High-beam System
Do not overly rely on the Adaptive High-b eam System. Always drive safely, taking care to observe your surroundings and turning the high beams on or off manually if neces- sary.
■To prevent incorrect operation of the Adaptive High-beam System
Do not overload the vehicle.

■Front door opening linked windshield wiper stop function (vehicles with rain-sensing windshield wipers)
When “AUTO” is selected and the windshield wipers are operating, if a front door is
opened, the operation of the windshield wipers will be stopped to prevent anyone near the vehicle from being sprayed by water from the wipers, provided the vehicle is stoppedwith the parking brake applied or the shift leve r in P. When the front door is closed, wiper
operation will resume.
■Customization
Some functions can be customized. ( P. 740)
WARNING
■Caution regarding the use of windshield wipers in AUTO mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or the wind- shield is subject to vibration in AUTO mode. Take care that your fingers, etc. do not
become caught in th e windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes warm. The
fluid may freeze on the windshield and cause low visibility. This may lead to an accident, resulting in death or serious injury.
■When the washer nozzle heaters are operating (if equipped)

WARNING
■Limitations of the pre-crash safety system
●The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
Do not use the pre-crash safety system instead of normal braking operations under any circumstances. This system will not pr event collisions or lessen collision damage or injury in every situation. Do not overly rely on this system. Failure to do so may lead
to an accident, resulting in death or serious injury.
●Although this system is designed to help avoid a collision or help reduce the impact of the collision, its effectiveness may change according to various conditions, therefore
the system may not always be able to achieve the same level of performance. Read the following conditions carefully. Do not overly rely on this system and always drive carefully.
• Conditions under which the system may oper ate even if there is no possibility of a collision: P. 307 • Conditions under which the system may not operate properly: P. 310
●Do not attempt to test the operation of the pre-crash safety system yourself, as the system may not operate properly, possibly leading to an accident.
■Pre-crash braking*3
●When the pre-crash braking function is operating, a large amount of braking forcewill be applied.
●If the vehicle is stopped by the operation of the pre-crash braking function, the pre- crash braking function operation will be canceled after approximately 2 seconds. Depress the brake pedal as necessary.
●The pre-crash braking function may not operate if certain operations are performedby the driver. If the accelerator pedal is being depressed strongly or the steering wheel is being turned, the system may determine that the driver is taking evasive
action and possibly prevent the pre-crash braking function from operating.
●In some situations, while the pre-crash brakin g function is operating, operation of the function may be canceled if the accelerator pedal is depressed strongly or the steer-
ing wheel is turned and the system determines that the driver is taking evasive action.
●If the brake pedal is being depressed, the system may determine that the driver is tak- ing evasive action and possibly delay the operation timing of the pre-crash braking
function.
*3: Depending on the region in which the vehicle was sold, the pre-crash braking func-
tion may not be available.
