*2 : To maintain the best braking performance and ABS/ESC performance, we recommend
that you use fluid that conform to specifications.
*3 : If the front/rear differential is submerged, visit an authorized retailer of Genesis Branded
products to replace the differential oil.
*4 : If the above recommended specification oil is not available, SAE 0W-30 grade synthetic
oil can be used. If mineral oil or semi-synthetic oil is used, it is a severe maintenance

Side View Mirrors
ORG3050026
Your vehicle is equipped with both left-
hand and right-hand side view mirrors.
The mirrors can be adjusted remotely
with the mirror adjustment control
switch. The side view mirrors can be
folded to help prevent damage when
going through an automatic car wash or
when passing through a narrow street.
The right side view mirror is convex.
Objects seen in the mirror are closer than
they appear.
Use the inside rear view mirror or look
back directly to determine the actual
distance of other vehicles prior to
changing lanes.
Make sure to adjust the side view mirrors
to your desired position before you begin
driving.
WARNING
Do not adjust or fold the side view
mirrors while driving. This may cause
loss of vehicle control resulting in an
accident.
NOTICE
• Do not scrape ice off the mirror face;
this may damage the surface of the
glass.
• If the mirror is jammed with ice, do
not adjust the mirror by force. Use an
approved spray de-icer (not radiator
antifreeze) spray, or a sponge or soft
cloth with very warm water, or move
the vehicle to a warm place and
allow the ice to melt.
• Do not clean the mirror with harsh
abrasives, fuel or other petroleum
based cleaning products.

Fuel Filler Door
Opening the fuel filler door
ORG3050052
1. Turn the engine off.
2. Ensure the driver’s door is unlocked.
3. Push the fuel filler door near the 3
o’clock position.
ORG3050053
4. Pull the fuel filler door (1) outward to
access the fuel tank cap.
5. To remove the fuel tank cap (2), turn
it counterclockwise. You may hear a
hissing noise as the pressure inside
the tank equalizes.
6. Place the cap on the fuel filler door.
Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break the
ice and release the door. Do not pry on the
door. If necessary, spray around the door
with an approved deicer fluid (do not use
radiator antifreeze) or move the vehicle to
a warm place and allow the ice to melt.
Closing the fuel filler door
1. To install the fuel tank cap, turn it
clockwise until it “clicks” one time.
2. Close the fuel filler door until it is
latched securely.
Information
The fuel filler door will not close if the
driver’s door is locked. If you lock the
driver’s door while fueling, unlock it
before closing the fuel filler door.

heights (underpass joining section,
grade separated intersections, etc.).
Always pay attention to road and
driving conditions while driving.
WARNING
• When you are towing a trailer or
another vehicle, make sure that you
turn off Blind-Spot Safety system.
• Blind-Spot Safety system may not
operate normally if interfered by
strong electromagnetic waves.
• Blind-Spot Safety system may not
operate for 15 seconds after the

Driver Assistance system
7-94
• The vehicle will accelerate if the
driver depresses the accelerator
pedal while Navigation-based Smart
Cruise Control is operating, and
the system will not decelerate the
vehicle.
• If the driver accelerates and
releases the accelerator pedal while
Navigation-based Smart Cruise
Control is operating, the vehicle may
not decelerate sufficiently or may
rapidly decelerate to a safe speed.
• If the curve is too large or too small,
Navigation-based Smart Cruise
Control may not operate.
• Navigation-based Smart Cruise
Control will automatically be
cancelled when you leave the
highway (or motorway) main road.
Always pay attention to road and
driving conditions while driving.
Information
• The speed information on the cluster
and navigation may differ.
• The time gap could occur between
the navigation’s guidance and when
Navigation-based Smart Cruise Control
operation starts and ends.
• Even if you are driving at a speed lower
than Smart Cruise Control set speed,
acceleration may be limited by the
curve sections ahead.
• If Navigation-based Smart Cruise
Control is operating while leaving the
main road to enter an interchange,
junction, rest area, etc., the system may
operate for a certain period of time.
• Deceleration by Navigation-based
Smart Cruise Control may feel it is not
sufficient due to road conditions such
as uneven road surfaces, narrow lanes,
etc.
Information
