• Highway Driving Assist will turn off automatically under the following
situations:
- Driving on roads that Highway Driving Assist does not operate, such
as a rest area, intersection, junction,
etc.
- The navigation does not operate properly such as when the navigation
is being updated or restarted
• Highway Driving Assist may inadvertently operate or turn off

(navigation information) and
surroundings.
• Lane Following Assist function may be temporarily disabled when the front
view camera cannot detect lanes
properly or the hands-off warning is on.
• You may not hear the warning sound of Highway Driving Assist if the
surrounding is noisy.
• If the vehicle is driven at high speed above a certain speed at a curve, your
vehicle may drive to one side or may
depart from the driving lane.
• When you are towing a trailer or another vehicle, turn off Highway
Driving Assist for safety reasons.
• The hands-off warning message may appear early or late depending on how
the steering wheel is held or road
conditions. Always have your hands on
the steering wheel while driving.
• For your safety, please read the owner's manual before using the Highway
Driving Assist. • Highway Driving Assist will not operate
when the vehicle is started, or when the
detecting sensors or navigation is being
initialized.

Explanation of Scheduled
Maintenance Items
Cooling System
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Gear Fluid
The gear fluid should be inspected and
replaced according to the intervals
specified in the maintenance schedule.
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake Fluid
Check the brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX marks on
the side of the reservoir. Use only
hydraulic brake fluid conforming to DOT 4
specification.
Brake Discs, Pads, Calipers
and Rotors
Check the pads, the discs, and the rotors
for any excessive wear-out. Inspect
calipers for any fluid leakage.
Suspension Mounting Bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.
Steering Gear Box, Linkage &
Boots/Lower Arm Ball Joint
With the vehicle stopped and the vehicle
off, check for excessive free-play in the
steering wheel. Check the linkage for
bends or damage. Check the dust boots
and ball joints for deterioration, cracks, or
damage.
Replace any damaged parts.
Drive Shafts and Boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if
necessary, repack the grease.
Air Conditioning Refrigerant
Check the air conditioning lines and
connections for leakage and damage.

Appearance Care
Exterior Care
NOTICE If you park your vehicle near a stainless
steel sign or glass facade building, the
vehicle’s exterior plastic parts such as a
bumper, spoiler, garnish, light or side
view mirror might be damaged due to
sunlight reflected from the sign or
building. To prevent damage of the
exterior plastic parts, you should avoid
parking in areas where light may be
reflected or use a car cover. (The exterior
plastic parts applied to your vehicle may
vary.)

Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.
Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road
driving, you should wash it after each
off-road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are kept clear
and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, should be used.
After washing, rinse the vehicle
thoroughly with lukewarm or cold water.
Do not allow soap to dry on the finish.
High-pressure washing
• When using high-pressure washers,
make sure to maintain sufficient
distance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
• Do not spray the camera, sensors or its surrounding area directly with a high
pressure washer. Shock applied from
high pressure water may cause the
device to not operate normally.
• Do not bring the nozzle tip close to boots (rubber or plastic covers) or
connectors as they may be damaged if
they come into contact with high
pressure water.
WARNING After washing the vehicle, test the brakes
while driving slowly to see if they have
been affected by water before getting on
the road. If braking performance is
impaired, dry the brakes by applying
them lightly while maintaining a slow
forward speed.
