Guide to dial settings
AFS (Adaptive Front-lighting System) secures excellent visibility at
intersections and on curves by automatically adjusting the direction of
the light axis of the headlights according to vehicle speed and the
degree of the tire’s angle as controlled by steering input.
AFS operates at speeds of 10 km/h (6 mph) or higher.

Deactivating AFS

CAUTION
When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cause injury.
Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.
When refueling
Observe the following precautions to prevent fuel overflowing from the fuel
tank:
Securely insert the fuel nozzle into the fuel filler neck.
Stop filling the tank after the fuel nozzle automatically clicks off.
Do not top off the fuel tank.
NOTICE
Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.

Maintenance and care
CAUTION
Pre-driving check
Check that the hood is fully closed and locked.
If the hood is not locked properly, it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.
After installing the support rod into the slot
Make sure the rod supports the hood securely from falling down on to your
head or body.
NOTICE
When closing the hood
Be sure to return the support rod to its clip before closing the hood. Closing
the hood with the support rod up could cause the hood to bend.
