Emergency Precautions
Tires
When replacing the tires, be sure to
equip all four tires with the tire and
wheel of the same size, type, tread,
brand and load-carrying capacity.
In an emergency situation, a com-
pact spare tire may be used. But, do
not use the compact spare tire con-
tinuously. Repair or replace the origi-
nal tire as soon as possible to avoid
failure of the differential or AWD sys-
tem.
Exercise extreme caution driv-
ing up or down steep hills. The
vehicle may flip depending on
the grade, terrain and water/
mud conditions.
WARNING
Do not use tire and wheel with
different size and type from the
one originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to steering
failure or rollover causing seri-
ous injury.

The severe weather conditions of winter quickly wear out tires and cause
other problems. To minimize winter driving problems, you should take the fol-
lowing suggestions:
Snow or Icy Conditions
You need to keep sufficient distance between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid acceleration, sudden brake applica-
tions, and sharp turns are potentially very hazardous practices. During decel-
eration, use engine braking to the fullest extent. Sudden brake applications on
snowy or icy roads may cause the vehicle to skid.
To drive your vehicle in deep snow, it may be necessary to use snow tires or
to install tire chains on your tires.
Always carry emergency equipment. Some of the items you may want to carry
include tire chains, tow straps or chains, a flashlight, emergency flares, sand,
a shovel, jumper cables, a window scraper, gloves, ground cloth, coveralls, a
blanket, etc.
We recommend you use snow tires when road temperature is below 45°F
(7°C). Refer to the below chart, and mount the recommended snow tire for
your vehicle.
If you mount snow tires on your vehicle, make sure to use the same inflation
pressure as the original tires. However, if you mount 245/45R19 size tire on
the rear, the tire inflation pressure should maintain 35psi. Mount snow tires on
all four wheels to balance your vehicle's handling in all weather conditions.
The traction provided by snow tires on dry road may not be as high as your
vehicle's original equipment tires. Check with the tire dealer for maximum
speed recommendations.
Information
Do not install studded tires without first checking local, state and municipal reg-
ulations for possible restrictions against their use.

Chain Installation
When installing AutoSock®(fabric
snow chain), follow the manufactur-
er's instructions and mount them as
tightly as possible. Drive slowly (less
than 20 mph (30 km/h)) with chains
installed. If you hear the chains con-
tacting the body or chassis, stop and
tighten them. If they still make con-
tact, slow down until the noise stops.
Remove the AutoSock
®(fabric snow
chain) as soon as you begin driving
on cleared roads.
When mounting AutoSock
®(fabric
snow chain), park the vehicle on
level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emer-
gency warning device behind the
vehicle (if available).
Always place the vehicle in P (Park),
apply the parking brake and turn off
the engine before installing tire
chains.
When using AutoSock
®(fabric
snow chain):
Wrong size chains or improperly installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
If you hear noise caused by chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage, retighten the chains after driving
0.3~0.6 miles (0.5~1.0 km).
AutoSock
®is a Registered trade-
mark of AutoSock.
Winter Precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Change to "winter weight" oil ifnecessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
retailer of Genesis Branded prod-
ucts.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized retailer of Genesis
Branded products or a service sta-
tion.

Tire Pressure Monitoring
System
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not oper-
ating properly. The TPMS malfunc-
tion indicator is combined with the
low tire pressure telltale. When the
system detects a malfunction, the
telltale will flash for approximately
one minute and then remain continu-
ously illuminated. This sequence will
continue upon subsequent vehicle
start-ups as long as the malfunction
exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunc-
tions may occur for a variety of rea-
sons, including the installation of
replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the
TPMS to continue to function proper-
ly.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
may cause loss of vehicle con-
trol resulting in an accident.
WARNING

When driving with the compact spare
tire mounted to your vehicle:
Check the tire pressure afterinstalling the compact spare tire.
The compact spare tire should be
inflated to 60 psi (420 kPa).
Do not take this vehicle through an automatic car wash while the com-
pact spare tire is installed.
Do not use the compact spare tire on any other vehicle because this
tire has been designed especially
for your vehicle.
The compact spare tire’s tread life is shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn com-
pact spare tires with the same size
and design, mounted on the same
wheel.
Do not use more than one compact spare tire at a time.Information
When the original tire and wheel are
repaired and reinstalled on the vehi-
cle, the lug nut torque must be set cor-
rectly. The correct lug nut tightening
torque is 79~94 lbf·ft (11~13 kgf·m).
To prevent damaging the compact
spare tire and your vehicle:
Drive slowly enough for the roadconditions to avoid all hazards,
such as a potholes or debris.
Avoid driving over obstacles. The compact spare tire diameter
is smaller than the diameter of a
conventional tire and reduces
the ground clearance approxi-
mately 1 inch (25 mm).
Do not use tire chains on the compact spare tire. Because of
the smaller size, a tire chain will
not fit properly.
Do not use the compact spare tire on any other wheels, nor
should standard tires, snow
tires, wheel covers or trim rings
be used with the compact spare
wheel.

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 pres-
sure. Tires with too much or
too little pressure wear
unevenly causing poor han-
dling.
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 effec-
tiveness, steering) control, or
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 recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle's Anti-Lock Brake System
(ABS) resulting in a serious
accident.

Maintenance
Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
The front tire size is different from the
rear tire size. So when you rotate tires,
check the tire and wheel size.
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.
Improper wheel weights can dam-
age your vehicle’s aluminum
wheels. Use only approved wheel
weights.
