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.
■ Windshield wiper-linked automatic headlights
When the headlight switch is in , if the windshield wipers operate for
approximately 10 seconds, the headlights will turn on automatically. (If the
windshield wipers are operated due to oper ation of the windshield washers,
the headlights will not turn on automatic ally.) In this case, the headlights will
automatically turn off approximately 60 seconds after the windshield wipers
stop operating.

● The headlights and/or tail lights are on.
● The key is removed from the engine switch (vehicles without a keyless
access with push button start system) or the push-button ignition switch
is turned off (vehicles with a keyless access with push button start sys-
tem).
● The light switch is in , or .
This function will be canceled in any of the following situations:
● When the engine switch is turned to the “ON” position (vehicles without a

■How to use the rear view camera
●When washing your vehicle with a high-pressure washer, do not allow the
water to contact the rear view camera directly. Entry of water into the cam-
era lens may result in condensation on the lens, malfunction, fire or elec-
tric shock.
● Since the rear view camera is a precision device, do not subject it to
strong impacts. Otherwise, malfunction, fire or electric shock may occur.
● If mud or snow sticks to or is frozen on the rear view camera, very carefully
remove it. Otherwise, damage to the rear view camera may cause a fire or
electric shock. Pour water or lukewarm water over the rear view camera to
remove mud and ice, and wipe it with a soft, dry cloth.
● When replacing a fuse, be sure to use a fuse with the specified rating. Use
of a fuse with a different rating may result in a malfunction.
● If the rear view camera is used for a long time while the engine is not run-
ning, the battery may become completely discharged.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■Pre-winter preparations
● Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Washer fluid
● Have a service technician inspect the condition of the battery.
● Have the vehicle fitted with four snow tires.
Make sure to install 4 tires that are of the specified size, and that
all 4 tires are the same for the following items:
•Size
• Circumference
• Speed symbol
• Load index
• Construction
• Manufacturer
• Brand (tread pattern)
• Degrees of wear
Also, make sure to use tire chains that match the size of the tires.
■Before driving the vehicle
Perform the following according to the driving conditions.
● Do not try to forcibly open a window or move a wiper that is
frozen. Pour warm water over the frozen area to melt the ice.
Wipe away the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.

WARNING
■To prevent the windshield from fogging up
Do not set the air outlet selection dial to during cool air operation in
extremely humid weather. The difference between the temperature of the
outside air and that of the windshield can cause the outer surface of the
windshield to fog up, blocking your vision.
CAUTION

Ventilation and air conditioning odors
● To let fresh air in, set the air condi tioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately after the air conditioni ng system is started in automatic
mode.
