WARNING
Take the following precautions when
using Rear Cross-Traffic Collision-
Avoidance Assist:
• For your safety, change the Settings
after parking the vehicle at a safe
location.
• If any other system’s warning
message is displayed or audible
warning is generated, Rear Cross-
Traffic Collision- Avoidance Assist’s
warning message may not be
displayed and audible warning may
not be generated.
• You may not hear the warning sound
of Rear Cross-Traffic Collision-
Avoidance Assist if the surrounding
is noisy.
• Rear Cross-Traffic Collision-
Avoidance Assist may not operate if
the driver applies the brake pedal to
avoid collision.
• During Rear Cross-Traffic Collision-
Avoidance Assist operation, the
vehicle may stop suddenly injuring
passengers and shifting loose
objects. Always have the seat belt on
and keep loose objects secured.
• Even if there is a problem with Rear
Cross-Traffic Collision- Avoidance
Assist, the vehicle’s basic braking
performance will operate properly.
• When Rear Cross-Traffic Collision-
Avoidance Assist is operating,
braking control by the function
will automatically cancel when the
driver excessively depresses the
accelerator pedal.
• Rear Cross-Traffic Collision-
Avoidance Assist does not operate
in all situations or cannot avoid all
collisions.
• Rear Cross-Traffic Collision-
Avoidance Assist may warn the
driver late or may not warn the driver
depending on the road and driving
conditions.• The driver is solely responsible to
operate the vehicle in a safe manner.
Do not solely depend on Rear Cross-
Traffic Collision- Avoidance Assist.
Rather, maintain a safe braking
distance, and if necessary, depress
the brake pedal to reduce driving
speed or to stop the vehicle.
• Never deliberately operate Rear
Cross-Traffic Collision- Avoidance
Assist on people, animal, objects,
etc. It may cause serious injury or
death.
CAUTION
The brake control may not operate
properly depending on the status of
ESC (Electronic Stability Control).
There will only be a warning when:
-The ESC (Electronic Stability Control)
warning light is on
-ESC (Electronic Stability Control) is
engaged in a different function
Information
If braking is assisted by Rear Cross-
Traffic Collision-Avoidance Assist, you
must immediately depress the brake pedal
and check vehicle surroundings.
-Brake control ends when you depress the
brake pedal with sufficient power.
-After shifting the gear to R (Reverse),
braking control operates once for left and
right vehicle approach.

10. Install the spare tire onto the studs of
the hub.
11. Tighten the lug nuts with your fingers
onto the studs with the smaller end of
the lug nuts closest to the wheel.
12. Lower the vehicle to the ground
by turning the jack handle
counterclockwise.
OTL065007OTL065007
13. Use the wheel lug wrench to tighten
the wheel nuts in the order shown.
Double-check each wheel nuts until
they are tight. After changing tires,
have an authorized HYUNDAI dealer
tighten the wheel nuts to their proper
torque as soon as possible. The wheel
nuts should be tightened to 79~94
lbf.ft (11~13 kgf.m).
If you have a tire gauge, check the
tire pressure (see “Tires and Wheels”
section in chapter 2 for tire pressure
instructions.). If the pressure is lower or
higher than recommended, drive slowly
to the nearest service station and adjust
it to the recommended pressure. Always
reinstall the valve cap after checking
or adjusting tire pressure. If the cap
is not replaced, air may leak from the
tire. If you lose a valve cap, buy another
and install it as soon as possible. After
changing tires, secure the flat tire and
return the jack and tools to their proper
storage locations.
NOTICE
Check the tire pressure as soon as
possible after installing a spare tire.
Adjust it to the recommended pressure.
CAUTION
Your vehicle has metric threads on the
studs and wheel nuts. Make certain
during tire changing that the same nuts
that were removed are reinstalled. If
you have to replace your wheel nuts
make sure they have metric threads to
avoid damaging the studs and ensure
the wheel is properly secured to the
hub. Consult an authorized HYUNDAI
dealer for assistance.
WARNING
Wheel studs
If the studs are damaged, they may lose
their ability to retain the wheel. This
could lead to the loss of the wheel and a
collision resulting in serious injuries.
If any of the equipment such as the jack,
wheel nuts, studs, or other equipment
is damaged or in poor condition, do not
attempt to change the tire and call for
assistance.

Storing the Flat Tire
The full size flat tire should be stored
and fixed in the vehicle until you reach
a service station.
Information
Do not store the flat tire on the spare
tire carrier underneath your vehicle.

1. Take out the strap which is stored in
the storage box under the right rear
seat. Connect the two straps with the
buckle, if necessary, before using the
strap to fix the flat tire.
2. Place the flat tire on the floor of the
bed area.
3. Pass one end of the strap through the
wheel center and connect both strap
hooks to each D-rings (A-A’ or B-B’).
ONX4OB081026ONX4OB081026
4. Pull the strap (1) to tighten the strap
firmly.
5. Try moving the flat tire to see if it is
properly secured.
CAUTION
Never leave the flat tire unfixed in the
vehicle. An unsecured flat tire may
cause damage to the vehicle when the
vehicle makes sharp turns, suddenly
stops, or is in an accident.

Maintenance
9-14
Engine Oil and Filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the vehicle
is being driven in severe conditions,
more frequent oil and filter changes are
required.
Drive Belts
Inspect all drive belts for evidence
of cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked
periodically for proper tension and
adjusted as necessary.
Information
When you are inspecting the belt, turn the
engine off.
Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
We recommend an authorized HYUNDAI
dealer replace any damaged or leaking
parts immediately.
Fuel Filter
The fuel filter is considered to be
maintenance free but periodic inspection
is recommended for this maintenance
depends on fuel quality. If there are
some important matters like fuel flow
restriction, surging, loss of power, hard
starting problem etc., replace the fuel
filter immediately. Consult an authorized
HYUNDAI dealer for details.
Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Your
HYUNDAI dealer will help to determine if
replacement is needed.
Vacuum Crankcase Ventilation
Hoses
Inspect the surface of hoses for evidence
of heat and/or mechanical damage.
Hard and brittle rubber, cracking,
tears, cuts, abrasions, and excessive
swelling indicate deterioration. Particular
attention should be paid to examine
those hose surfaces nearest to high heat
sources, such as the exhaust manifold.
Inspect the hose routing to ensure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat
damage or mechanical wear. Inspect
all hose connections, such as clamps
and couplings, to make sure they are
secure, and that no leaks are present.
Hoses should be replaced immediately if
there is any evidence of deterioration or
damage.
