A : Front,
B : Rear
If towing is necessary, we recommend
you have it done by an authorized
retailer of Genesis Branded products or a
commercial tow truck service.
If 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 working
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:
• Press the Engine Start/Stop button
to the ACC position so the steering
wheel is not locked.
• Shift the gear to N (Neutral).
• Release the parking brake.
• Depress the brake pedal with more
force than normal as 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.

Maintenance
Owner Maintenance Schedule
When you stop for fuel:

[Check the coolant level in the engine
coolant reservoir or the liquid-cooled
intercooler coolant reservoir.

[Check the windshield washer fluid
level.

[Check for low or under-inflated tires.
WARNING
Be careful when checking your coolant
level if the motor compartment is hot.
This may result in coolant being blown
out of the opening and cause serious
burns and other injuries.
While operating your vehicle:

[Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.

[Check for vibrations in the steering
wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.

[Notice if your vehicle constantly turns
slightly or “pulls” to one side when
traveling on smooth, level road.

[When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.

[If any slipping or changes in the
operation of your transmission occurs,
check the transmission fluid level.

[Check the automatic transmission P
(Park) function.

[Check the parking brake.

[Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:

[Check coolant level in the engine
coolant reservoir.

[Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.

[Check the inflation pressures of all
tires including the spare for tires that
are worn, show uneven wear, or are
damaged.

[Check for loose wheel lug nuts.
At least twice a year: (for example,
every Spring and Autumn)

[Check radiator, heater and air
conditioning hoses for leaks or
damage.

[Check windshield washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.

[Check headlight alignment.

[Check muffler, exhaust pipes, shields
and clamps.

[Check the seat belts for wear and
function.
At least once a year:

[Clean body and door drain holes.

[Lubricate door hinges and hood
hinges.

[Lubricate door and hood locks and
latches.

[Lubricate door rubber weather strips.

[Check the air conditioning system.

components in the engine. Engine oil
consumption while driving is normal,
and it is necessary to check and refill the
engine oil regularly. Also, check and refill
the oil level within the recommended
maintenance schedule to prevent
deterioration of oil performance.
Check the engine oil following the below
procedure.
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on the level
ground in P (Park) with the parking
brake set and the wheels blocked.
3. Turn the engine on and warm
the engine up until the coolant
temperature reaches a constant
normal temperature.
4. Turn the engine off, remove the oil
filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to return
to the oil pan.
5. Wipe the dipstick clean and re-insert
it fully.

WARNING
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of SERIOUS
INJURY or DEATH, take the
following precautions:

[Inspect your tires monthly for
proper inflation as well as wear
and damage.

[The recommended cold tire
pressure for your vehicle can be
found in this manual and on the
tire label located on the driver’s
side center pillar. Always use a
tire pressure gauge to measure
tire pressure. Tires with too
much or too little pressure wear
unevenly causing poor handling.

[Check the pressure of the
spare every time you check the
pressure of the other tires on
your vehicle.

[Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, or traction.

[ALWAYS replace tires with the
same size, type, construction and
tread pattern as each tire that
was originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.
Tire Care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended
tire inflation pressures and stay
within the load limits and weight
distribution recommended for your
vehicle.
ORS012024N
All specifications (sizes and
pressures) can be found on a label
attached to the driver’s side center
pillar.
Recommended Cold Tire
Inflation Pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold tires” means the
vehicle has not been driven for at
least three hours or driven less than
one mile (1.6 km).
Warm tires normally exceed
recommended cold tire pressures
by 4 to 6 psi (28 to 41 kPa). Do not
release air from warm tires to adjust
the pressure or the tires will be
under-inflated. For recommended
inflation pressure, refer to “Tire and
Wheels” section in chapter 2.
TIRES AND WHEELS

9-36
Maintenance
Wheel Alignment and Tire
Balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
NOTICE
Incorrect wheel weights can
damage your vehicle’s aluminum
wheels. Use only approved wheel
weights.
Tire Replacement
ORS091057
A : Tread wear indicator
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1/16 inch (1.6 mm) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before
replacing the tire.
WARNING
To reduce the risk of DEATH or
SERIOUS INJURY:

[Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, and traction.

[Always replace tires with the
same size as each tire that was
originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.

[When replacing tires (or wheels),
it is recommended to replace
the two front or two rear tires (or
wheels) as a pair. Replacing just
one tire can seriously affect your
vehicle’s handling.

[Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, Genesis Branded Vehicle
recommends that tires be
replaced after six (6) years of
normal service.

[Heat caused by hot climates or
frequent high loading conditions
can accelerate the aging process.
Failure to follow this warning
may cause sudden tire failure,
which could lead to a loss of
vehicle control resulting in an
accident.

Maintenance
Keep your garage dry
Don’t park your vehicle in a damp,
poorly ventilated garage. This creates
a favorable environment for corrosion.
This is particularly true if you wash your
vehicle in the garage or drive it into the
garage when it is still wet or covered with
snow, ice or mud. Even a heated garage
can contribute to corrosion unless it is
well ventilated so moisture is dispersed.
Keep paint and trim in good condition
Scratches or chips in the finish should
be covered with “touch-up” paint as
soon as possible to reduce the possibility
of corrosion. If bare metal is showing
through, the attention of a qualified body
and paint shop is recommended.
Bird droppings are highly corrosive and
may damage painted surfaces in just a
few hours. Always remove bird droppings
as soon as possible.Interior Care
Interior general precautions
Prevent caustic solutions such as
perfume and cosmetic oil, from
contacting the interior parts because
they may cause damage or discoloration.
If they do contact the interior parts,
wipe them off immediately. See the
instructions for the proper way to clean
vehicle interior surfaces.
NOTICE

[Never allow water or other liquids
to come in contact with electrical/
electronic components inside the
vehicle as this may damage them.

[When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alcohol
content solutions. If you use high
alcohol content solutions or acid/
alkaline detergents, the color of the
leather may fade or the surface may
get stripped off.
