WARNING
Take the following precautions when
using Rear Cross-Traffic Safety system:
For your safety, change the Settings
after parking the vehicle at a safe
location.
If any other function’s warning
message is displayed or audible
warning is generated, Rear Cross-
Traffic Safety system’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 Safety system if
the surrounding is noisy.
Rear Cross-Traffic Safety system may
not operate if the driver applies the
brake pedal to avoid collision.
During Rear Cross-Traffic Safety
system 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 Safety system, the
vehicle’s basic braking performance
will operate normally.
When Rear Cross-Traffic Safety
system is operating, braking control
by the function will automatically
cancel when the driver excessively
depresses the accelerator pedal.
Rear Cross-Traffic Safety system does
not operate in all situations or cannot
avoid all collisions.
Rear Cross-Traffic Safety system 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 Safety system. 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 Safety system 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).

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.
Check and tighten the wheel lug nuts
after driving over 30 mile (50 km) if
tires are replaced. Recheck the tire
wheel lug nuts after driving over 620
mile (1,000 km).
CAUTION
Your vehicle has metric threads on the
studs and wheel bolts. Make certain
during tire changing that the same bolts
that were removed are reinstalled. If
you have to replace your wheel bolts
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.
If any of the equipment such as the jack,
wheel bolts, studs, or other equipment
is damaged or in poor condition, do not
attempt to change the tire and call for
assistance.

and stay away from the tire when
filling it.

Emergency situations
8-34
WARNING
If your vehicle is equipped with a
rollover sensor, place the ignition
switch in the LOCK/OFF or ACC position
when the vehicle is being towed.
The side impact and curtain air bag
may deploy if the sensor detects the
situation as a rollover.

Emergency Towing
If towing is necessary, we recommend
you have it done by an authorized
HYUNDAI dealer or a commercial tow
truck service.
If a towing service is not available in
an emergency, your vehicle may be
temporarily towed using a cable or chain
secured to the emergency towing hook
at the front (or rear) of the vehicle.
Use extreme caution when towing the
vehicle with a cable or chain. A driver
must be in the vehicle to steer it and
operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a short
distance and at low speeds. Also, the
wheels, axles, power train, steering and
brakes must all be in good condition.
CAUTION
The driver must be in the vehicle for
steering and braking operations when
the vehicle is being towed. Passengers
other than the driver must not be in the
vehicle.
Always follow these emergency towing
precautions:
Place the ignition switch in the ACC
position so the steering wheel is not
locked. (if equipped)
Place the shift lever in N (Neutral).
Release the parking brake.
Depress the brake pedal with more
force than normal since you will have
reduced braking performance.
More steering effort will be required
because the power steering system
will be disabled.
Use a vehicle heavier than your own to
tow your vehicle.
The drivers of both vehicles should
communicate with each other
frequently.
Before emergency towing, check that
the hook is not broken or damaged.
Fasten the towing cable or chain
securely to the hook.
Do not jerk the hook. Apply steady
and even force.

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
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 (for gasoline engine)
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. Make sure
a new vapor hose or fuel filler cap is
correctly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
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.
Air cleaner filter
We recommend that the air cleaner filter
be replaced by an authorized HYUNDAI
dealer.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to
wipe the inside and outside of the boot
bottom of the ignition coil and the
insulator of the spark plug with a soft
cloth to prevent contamination of the
spark plug insulator.
