5Highway drivingTiresAdjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.✽
NOTICENever exceed the maximum tire inflation
pressure shown on the tires.
Fuel, engine coolant and engine oilHigh speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engine
oil.Drive beltA loose or damaged drive belt may result
in overheating of the engine.
WARNING
• Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
Always check tires for proper
inflation before driving. For prop-
er tire pressures, refer to “Tires
and wheels” in section 8.
• Driving on tires with no or insuffi- cient tread is dangerous. Worn-
out tires can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tires
should be replaced as soon as
possible and should never be
used for driving. Always check
the tire tread before driving your
car. For further information and
tread limits, refer to “Tires and
wheels” in section 7.

Driving your vehicle
More severe weather conditions of winter
result in greater wear and other prob-
lems. To minimize winter driving problem,
you should follow these suggestions:
Snowy or icy conditionsTo drive your vehicle in deep snow, it may
be necessary to use snow tires or to
install tire chains on your tires. If snow
tires are needed, it is necessary to select
tires equivalent in size and type of the
original equipment tires. Failure to do so
may adversely affect the safety and han-
dling of your car. Furthermore, speeding,
rapid acceleration, sudden brake appli-
cations, and sharp turns are potentially
very hazardous practices.
During deceleration, use engine braking
to the fullest extent. Sudden brake appli-
cations on snowy or icy roads may cause
skids to occur. You need to keep suffi-
cient distance between the vehicle in
operation in front and your vehicle. Also,
apply the brake gently. It should be noted
that installing tire chains on the tire will
provide a greater driving force, but will
not prevent side skids.✽NOTICETire chains are not legal in all states.
Check state laws before fitting tire
chains.
Snow tires If you mount snow tires on your vehicle,
make sure they are radial tires of the
same size and load range as the original
tires. Mount snow tires on all four wheels
to balance your vehicle’s handling in all
weather conditions. Keep in mind that the
traction provided by snow tires on dry
roads may not be as high as your vehi-
cle's original equipment tires. You should
drive cautiously even when the roads are
clear. Check with the tire dealer for max-
imum speed recommendations.Do not install studded tires without first
checking local, state and municipal regu- lations for possible restrictions againsttheir use.
WINTER DRIVING
WARNING
- Snow tire size
Snow tires should be equivalent in
size and type to the vehicle's stan-
dard tires. Otherwise, the safety
and handling of your vehicle may
be adversely affected.

5Tire chains Since the sidewalls of radial tires are
thinner, they can be damaged by mount-
ing some types of snow chains on them.
Therefore, the use of snow tires is rec-
ommended instead of snow chains. Do
not mount tire chains on vehicles
equipped with aluminum wheels; snow
chains may cause damage to the wheels.
If snow chains must be used, use wire-
type chains with a thickness of less than
0.47 in (12 mm). Damage to your vehicle
caused by improper snow chain use is
not covered by your vehicle manufactur-
ers warranty.
When using tire chains, install them on
the front tires only. Chain installation
When installing chains, follow the manu-
facturer's instructions and mount them as
tightly as you can. Drive slowly with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until it stops. Remove the
chains as soon as you begin driving on
cleared roads.
CAUTION
• Make sure the snow chains are
the correct size and type for yourtires. Incorrect snow chains can cause damage to the vehicle bodyand suspension and may not becovered by your vehicle manufac-turer warranty. Also, the snowchain connecting hooks may bedamaged from contacting vehicle components causing the snowchains to come loose from thetire. Make sure the snow chainsare SAE class “S” certified.
• Always check chain installation for proper mounting after drivingapproximately 0.3 to 0.6 miles (0.5to 1 km) to ensure safe mounting.Retighten or remount the chainsif they are loose.
WARNING - Mounting chains
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning flashers and place
a triangular emergency warning
device behind the vehicle if avail-
able. Always place the vehicle in P
(Park), apply the parking brake and
turn off the engine before installing
snow chains.

5Certification label
The certification label is located on
the driver's door sill at the center pil-
lar.
This label shows the maximum
allowable weight of the fully loaded
vehicle. This is called the GVWR
(Gross Vehicle Weight Rating). The
GVWR includes the weight of the
vehicle, all occupants, fuel and
cargo.
This label also tells you the maxi-
mum weight that can be supported
by the front and rear axles, called
Gross Axle Weight Rating (GAWR). To find out the actual loads on your
front and rear axles, you need to go
to a weigh station and weigh your
vehicle. Your dealer can help you with
this. Be sure to spread out your load
equally on both sides of the center-
line.
The label will help you decide how
much cargo and installed equipment
your vehicle can carry.
If you carry items inside your vehicle
- like suitcases, tools, packages, or
anything else - they are moving as
fast as the vehicle. If you have to stop
or turn quickly, or if there is a crash,
the items will keep going and can
cause an injury if they strike the driv-
er or a passenger.
OBH059070
WARNING -
Over loading
• Never exceed the GVWR for your vehicle, the GAWR for
either the front or rear axle
and vehicle capacity weight.
Exceeding these ratings can
cause an accident or vehicle
damage. You can calculate the
weight of your load by weigh-
ing the items (or people)
before putting them in the
vehicle. Be careful not to over-
load your vehicle.
(Continued)
(Continued)
• Do not load your vehicle anyheavier than the GVWR, either
the maximum front or rear
GAWR and vehicle capacity
weight. If you do, parts,
including tires on your vehicle
can break, and it can change
the way your vehicle handles
and braking ability. This could
cause you to lose control and
crash. Also, overloading can
shorten the life of your vehi-
cle.

WARNING
• Overloading your vehicle cancause heat buildup in your
vehicle's tires and possible
tire failure that could lead to a
crash.
• Overloading your vehicle can cause increased stopping dis-
tances that could lead to a
crash.
• A crash resulting from poor handling, vehicle damage, tire
failure, or increased stopping
distances could result in seri-
ous injury or death.
WARNING
- Loose cargo
Items you carry inside your
vehicle can strike and injure
occupants in a sudden stop or
turn, or in a crash.
• Put items in the cargo area of your vehicle. Try to spread the
weight evenly.
• Never stack items, like suit- cases, inside the vehicle
above the tops of the seats.
• Do not leave an unsecured child restraint in your vehicle.
• When you carry something inside the vehicle, secure it.
• Do not drive with a seat folded down unless necessary.
CAUTION
• Overloading your vehicle may
cause damage. Repairs wouldnot be covered by your warran-ty. Do not overload your vehicle.

What to do in an emergency
TIRE PRESSURE MONITORING SYSTEM (TPMS)(1) Low tire pressure telltale / TPMS malfunction indicator
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 efficiency 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
operating properly. The TPMS mal-
function indicator is combined with
the low tire pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the system
may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, 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.

6✽
NOTICEIf the TPMS indicator does not illu-
minate for 3 seconds when the igni-
tion switch is turned to the ON posi-
tion or engine is running, or if they
remain illuminated after coming on
for approximately 3 seconds, take
your car to your nearest authorized
HYUNDAI dealer and have the sys-
tem checked.
Low tire pressure tell-
tale
When the tire pressure monitoring
system warning indicator is illuminat-
ed, one or more of your tires is sig-
nificantly under-inflated.
If the telltale illuminates, immediately
reduce your speed, avoid hard cor-
nering and anticipate increased stop-
ping distances. You should stop and
check your tires as soon as possible.
Inflate the tires to the proper pres-
sure as indicated on the vehicle’s
placard or tire inflation pressure label
located on the driver’s side center pil-
lar outer panel. If you cannot reach a
service station or if the tire cannot
hold the newly added air, replace the
low pressure tire with the spare tire.
Then the Low Tire Pressure telltale
may turn on and illuminate after
restarting and about 20 minutes of
continuous driving before you have
the low pressure tire repaired and
replaced on the vehicle.
CAUTION
In winter or cold weather, the low tire pressure telltale may beilluminated if the tire pressurewas adjusted to the recom-mended tire inflation pressurein warm weather. It does notmean your TPMS is malfunction-ing because the decreased tem-perature leads to a proportionallowering of tire pressure.
When you drive your vehiclefrom a warm area to a cold areaor from a cold area to a warmarea, or the outside temperatureis greatly higher or lower, youshould check the tire inflationpressure and adjust the tires tothe recommended tire inflationpressure.

What to do in an emergency
TPMS (Tire Pressure
Monitoring System)
malfunction indicator
The TPMS malfunction indicator will
illuminate after it blinks for approxi-
mately one minute when there is a
problem with the Tire Pressure
Monitoring System. If the system is
able to correctly detect an under infla-
tion warning at the same time as sys-
tem failure then it will illuminate the
TPMS malfunction indicator.
Have the system checked by an
authorized HYUNDAI dealer as soon
as possible to determine the cause
of the problem.

WARNING
- Low pressure damage
Significantly low tire pressure
makes the vehicle unstable and
can contribute to loss of vehicle
control and increased braking
distances.
Continued driving on low pres-
sure tires can cause the tires to
overheat and fail.
CAUTION
• The TPMS malfunction indica- tor may be illuminated if thevehicle is moving around elec-tric power supply cables orradios transmitter such as atpolice stations, governmentand public offices, broadcast-ing stations, military installa-tions, airports, or transmittingtowers, etc. This can interferewith normal operation of theTire Pressure MonitoringSystem (TPMS).
• The TPMS malfunction indica- tor may illuminate if snowchains or some separatelypurchased devices such asnotebook computers, mobilecharger, remote starter, navi-gation etc. are used in thevehicle. This can interfere withnormal operation of the TirePressure Monitoring System(TPMS).
