Driving your vehicle
When the ECO mode is activated:
The acceleration response may beslightly reduced if the accelerator
pedal is depressed moderately.
The air conditioner performance may be limited.
The shift pattern of the automatic transmission/dual clutch transmission
may change.
The engine speed may be lower than when driving in NORMAL mode.
The above situations are normal condi-
tions when the ECO mode is activated to
improve fuel efficiency. Limitation of the ECO mode opera-
tion:
Even though ECO mode is selected and
there is no change in the ECO indicator :
When the coolant temperature is low,
ECO mode will be limited until engine
temperature is at normal operating
temperature.
When driving up a hill, ECO mode will be limited to provide better power
when driving uphill.
When driving the vehicle with the auto- matic transmission/ dual clutch trans-
mission gear shift lever in manual shift
mode, ECO mode will be limited
according to the shift position.SPORT mode
SPORT mode manages the
driving dynamics by automat-
ically adjusting the steering
effort, and the engine and
transmission control logic for enhanced
driver performance.
When SPORT mode is selected by pressing the DRIVE MODE button, the
SPORT indicator will illuminate.
Whenever the engine is restarted, the Drive Mode will revert back to NOR-
MAL mode. If SPORT mode is desired,
re-select SPORT mode from the
DRIVE MODE button.

Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may have
little or no contact with the road surface
and actually ride on the water. The best
advice is SLOW DOWN when the road is
wet.
The risk of hydroplaning increases as
the depth of tire tread decreases, refer
to "Tire Tread" in chapter 7.
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no high-
er than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or adversely
affect vehicle handling. This could lead to
sudden tire failure that may cause loss of
vehicle control resulting in an accident.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engineoil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may over-
heat the engine.
i
In a rollover crash, an unbelted per-
son is significantly more likely to
die than a person wearing a seat
belt. Make sure all passengers are
wearing their seat belts.

Don't place foreign objects or
materials in the engine com-partment
Placement of foreign object or materials
which prevent cooling of the engine, in
the engine compartment, may cause a
failure or combustion. The manufacturer
is not responsible for the damage caused
by such placement.
To keep locks from freezing
To keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into
the key opening. If a lock is covered with
ice, squirt it with an approved de-icing
fluid to remove the ice. If the lock is
frozen internally, you may be able to thaw
it out by using a heated key. Handle the
heated key with care to avoid injury.
Two labels on your driver's door sill
show how much weight your vehicle
was designed to carry: the Tire and
Loading Information Label and the
Certification Label.
Before loading your vehicle, familiar-
ize yourself with the following terms
for determining your vehicle’s weight
ratings, from the vehicle's specifica-
tions and the Certification Label:
Base Curb Weight
This is the weight of the vehicle
including a full tank of fuel and all
standard equipment. It does not
include passengers, cargo, or option-
al equipment.
Vehicle Curb Weight
This is the weight of your new vehicle
when you picked it up from your deal-
er plus any aftermarket equipment.
Cargo Weight
This figure includes all weight added
to the Base Curb Weight, including
cargo and optional equipment. GAW (Gross Axle Weight)
This is the total weight placed on
each axle (front and rear) - including
vehicle curb weight and all payload.
GAWR (Gross Axle Weight Rating)
This is the maximum allowable
weight that can be carried by a single
axle (front or rear). These numbers
are shown on the Certification Label.
The total load on each axle must
never exceed its GAWR.
GVW (Gross Vehicle Weight)
This is the Base Curb Weight plus
actual Cargo Weight plus passen-
gers.
GVWR (Gross Vehicle Weight
Rating)
This is the maximum allowable
weight of the fully loaded vehicle
(including all options, equipment,
passengers and cargo). The GVWR
is shown on the Certification Label
located on the driver’s door sill.

Certification label
The certification label is located on
the driver’s door sill at the center pil-
lar and shows the maximum allow-
able weight of the fully loaded vehi-
cle. 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).The total weight of the vehicle,
including all occupants, accessories,
cargo, and trailer tongue load must
not exceed the Gross Vehicle Weight
Rating (GVWR) or the 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. Be
sure to spread out your load equally
on both sides of the centerline.
Overloading your vehicle may
cause damage. Repairs would not
be covered by your warranty. Do
not overload your vehicle.
NOTICE
If you carry items inside your
vehicle (e.g., 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 driver or a passenger.

Put items in the cargo area of
your vehicle. Try to spread the
weight evenly.
Do not 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.
WARNING
OBH059070
Overloading
Never exceed the GVWR for
your vehicle, the GAWR for
either the front or rear axle
and vehicle capacity weight.
Exceeding these ratings can
affect your vehicle's handling
and braking ability, and cause
an accident.
Do not overload your vehicle.
Overloading your vehicle can
cause heat buildup in your
vehicle's tires and possible
tire failure, increased stop-
ping distances and poor vehi-
cle handling-all of which may
result in a crash.

What to do in an emergency
If the Engine Doesn't Turn
Over or Turns Over Slowly
Be sure the shift lever is in N (Neutral)or P (Park). The engine starts only
when the shift lever is in N (Neutral) or
P (Park).
Check the battery connections to be sure they are clean and tight.
Turn on the interior light. If the light dims or goes out when you operate the
starter, the battery is drained.
Do not push or pull the vehicle to start it.
This could cause damage to your vehi-
cle. See instructions for "Jump Starting"
provided in this chapter.
If the Engine Turns Over
Normally but Doesn't Start
Check the fuel level and add fuel if nec-
essary.
If the engine still does not start, have
your vehicle checked by an authorized
HYUNDAI dealer. Jump starting can be dangerous if done
incorrectly. Follow the jump starting pro-
cedure in this section to avoid serious
injury or damage to your vehicle. If in
doubt about how to properly jump start
your vehicle, we strongly recommend
that you have a service technician or tow-
ing service do it for you.

What to do in an emergency
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
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 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 properly.
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.
