Electronic stability program (ESP) (if equipped)
The Electronic Stability Program (ESP)
system is designed to stabilise the vehicle
during cornering manoeuvres. ESP
checks where you are steering and where
the vehicle is actually going. ESP applies
the brakes at individual wheels and
intervenes in the engine management
system to stabilise the vehicle. The Electronic Stability Program (ESP)system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESP will be effective in
preventing a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ESP is active.
✽✽
NOTICE
A click sound may be heard in the engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Program System is functioning proper-
ly.
WARNING
Never drive too fast for the road
conditions or too quickly when cor-
nering. Electronic stability program
(ESP) will not prevent accidents.
Excessive speed in turns, abruptmanoeuvres and aquaplaning onwet surfaces can still result in seri-
ous accidents. Only a safe and
attentive driver can prevent acci-
dents by avoiding manoeuvres that
cause the vehicle to lose traction.
Even with ESP installed, always fol-
low all the normal precautions for
driving - including driving at safe
speeds for the conditions.

E070600AFD-EA Good braking practices
After being parked, check to be surethe parking brake is not engaged and
that the parking brake indicator light is
out before driving away.
Driving through water may get the brakes wet. They can also get wet
when the car is washed. Wet brakes
can be dangerous! Your car will not
stop as quickly if the brakes are wet.
Wet brakes may cause the car to pull
to one side. To dry the brakes, apply the brakes
lightly until the braking action returns to
normal, taking care to keep the car
under control at all times. If the braking
action does not return to normal, stop
as soon as it is safe to do so and call
an authorised HYUNDAI dealer for
assistance.
Don't coast down hills with the car out of gear. This is extremely hazardous.
Keep the car in gear at all times, use
the brakes to slow down, then shift to a
lower gear so that engine braking will
help you maintain a safe speed.
Don't "ride" the brake pedal. Resting your foot on the brake pedal while driv-ing can be dangerous because it can
result in the brakes overheating and
losing their effectiveness. It also
increases the wear of the brake com-
ponents.
If a tyre goes flat while you are driving, apply the brakes gently and keep the
car pointed straight ahead while you
slow down. When you are moving
slowly enough for it to be safe to do so,
pull off the road and stop in a safe
place.
WARNING
Never press the ESP OFF button while ESP is operating. If the ESP is turned off while ESP is
operating, the vehicle may go out of
control.
To turn ESP off while driving, press
the ESP OFF button while driving
on a flat road surface.
WARNING
Whenever leaving vehicle or parking, always set the parking
brake as far as possible and fully
engage the vehicle's transaxle
into the park position. Vehicles
not fully engaged in park with the
parking brake set are at risk for
moving inadvertently and injur-
ing yourself or others.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the car whichcan injure occupants or pedestri-ans.

Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
kilometers (miles) you can get from a litre
(gallon) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-
ate rate. Don't make “kangaroo” starts or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-tion. Don't "ride" the brake or clutch pedal.
This can increase fuel consumption
and also increase wear on these com-
ponents. In addition, driving with your
foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may
lead to more serious consequences.
Take care of your tyres. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tyre
wear. Check the tyre pressures at leastonce a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting kerbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tyre wear and may
also result in other problems as well as
greater fuel consumption.
Keep your car in good condition. For better fuel economy and reduced
maintenance costs, maintain your carin accordance with the maintenance
schedule in Section 7. If you drive your
car in severe conditions, more frequentmaintenance is required (see Section
7 for details). Keep your car clean. For maximum
service, your vehicle should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel con-
sumption and also contribute to corro-sion.
Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel
economy.
Don't let the engine idle longer than necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.
Remember, your vehicle does not require extended warm-up. After the
engine has started, allow the engine to
run for 10 to 20 seconds prior to plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
Don't “labour” or “over-rev” the engine. Labouring is driving too slowly in toohigh a gear resulting in the engine
bucking. If this happens, shift to a lower
gear. Over-revving is racing the engine
beyond its safe limit. This can be avoid-
ed by shifting at the recommended
speeds.
ECONOMICAL OPERATION

537
Driving your vehicle
Fuel, engine coolant and engine oil:
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engineoil.
Drive belt:
A loose or damaged drive belt may result
in overheating of the engine.
WARNING
Underinflated or overinflated tyres can cause poor handling,
loss of vehicle control, and sud-den tyre failure leading to acci-
dents, injuries, and even death.
Always check the tyres for proper
inflation before driving. For prop-
er tyre pressures, refer to section
9, “Tyres and wheels”.
Driving on tyres with no or insuf- ficient tread is dangerous. Worn-out tyres can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tyresshould be replaced as soon as
possible and should never be
used for driving. Always check
the tyre tread before driving your
car. For further information and
tread limits, refer to section 7,
“Tyres and wheels”.

The more severe weather conditions of
winter result in greater wear and other
problems. To minimise the problems of
winter driving, you should follow thesesuggestions:
E120100AUN-EA
Snowy or Icy conditions
To drive your vehicle in deep snow, it may
be necessary to use snow tyres or to
install tyre chains on your tyres. If snow
tyres are needed, it is necessary to
select tyres equivalent in size and type of
the original equipment tyres. Failure to do
so may adversely affect the safety and
handling of your car. Furthermore,
speeding, rapid acceleration, sudden
brake applications, 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 notedthat installing tyre chains on the tyre will
provide a greater driving force, but will
not prevent side skids.
✽✽
NOTICE
Tyre chains are not legal in all states.
Check state laws before fitting tyrechains.
E120101AUN-EA
Snow tyres
If you mount snow tyres on your vehicle,
make sure they are radial tyres of the
same size and load range as the original
tyres. Mount snow tyres on all four
wheels to balance your vehicle’s han-
dling in all weather conditions. Keep in
mind that the traction provided by snow
tyres on dry roads may not be as high as
your vehicle's original equipment tyres.
You should drive cautiously even when
the roads are clear. Check with the tyre
dealer for maximum speed recommen-
dations.
Do not install studded tyres without first checking local, state and municipal regu-
lations for possible restrictions against their use.
WINTER DRIVING
WARNING - Snow tyre size
Snow tyres should be equivalent in
size and type to the vehicle's stan-
dard tyres. Otherwise, the safety
and handling of your vehicle may
be adversely affected.

Tyre chains
Since the sidewalls of radial tyres are
thinner, they can be damaged by mount-
ing some types of snow chains on them.
Therefore, the use of snow tyres is rec-
ommended instead of snow chains. Do
not mount tyre chains on vehicles
equipped with aluminium 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
15 mm (0.59 in). Damage to your vehicle
caused by improper snow chain use is
not covered by your vehicle manufactur-
ers warranty.
Install tyre chains only on the front tyres.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 yourtyres. Incorrect snow chains cancause damage to the vehicle body
and suspension and may not becovered by your vehicle manufac- turer warranty. Also, the snowchain connecting hooks may be
damaged from contacting vehiclecomponents causing the snowchains to come loose from the tyre. Make sure the snow chains
are SAE class “S” certified.
Always check chain installation for proper mounting after drivingapproximately 0.5 to 1 km (0.3 to
0.6 miles) to ensure safe mount-ing. Retighten or remount the chains if 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
park (P), apply the parking brake
and turn off the engine before
installing snow chains.1JBA4068

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.
✽✽NOTICE
The operating temperature range for an
immobiliser key is between -40°C to
80°C. If you heat an immobiliser key
above 80°C to open a frozen lock, you
may damage the transponder located in
the head of the key.
E120700AFD-EA
Use approved window washer
anti-freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the con-
tainer. Window washer anti-freeze is
available from an authorised HYUNDAI
dealer and most auto parts outlets. Donot use engine coolant or other types of
anti-freeze as these may damage thepaint finish.
E120800AUN-EA
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. If there is a risk the parking
brake may freeze, apply it only temporar-
ily while you put the gear selector lever in
P (automatic transaxle) or in first or
reverse gear (manual transaxle) and
block the rear wheels so the car cannot
roll. Then release the parking brake. E120900AUN
Don't let ice and snow accumu- late underneath
Under some conditions, snow and ice
can build up under the fenders and inter-
fere with the steering. When driving in
severe winter conditions where this may
happen, you should periodically check
underneath the car to be sure the move-
ment of the front wheels and the steering
components is not obstructed.
E121000AUN-EA
Carry emergency equipment
Depending on the severity of the weath-
er where you drive your car, you should
carry appropriate emergency equipment.
Some of the items you may want to carry
include tyre chains, tow straps or chains,
flashlight, emergency flares, sand, a
shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket,etc.

If you are considering towing with your
car, you should first check with your
country's Department of Motor Vehicles
to determine their legal requirements.
Since laws vary the requirements for tow-
ing trailers, cars, or other types of vehi-
cles or apparatus may differ. Ask an
authorised HYUNDAI dealer for further
details before towing.
Your vehicle can tow a trailer. To identify
what the vehicle trailering capacity is for
your vehicle, you should read the infor-
mation in “Weight of the trailer” thatappears later in this section.
Remember that trailering is different than
just driving your vehicle by itself.
Trailering means changes in handling,
durability, and fuel economy. Successful,
safe trailering requires correct equip-
ment, and it has to be used properly.This section contains many time-tested,
important trailering tips and safety rules.
Many of these are important for your
safety and that of your passengers.
Please read this section carefully before
you pull a trailer. Load-pulling components such as the
engine, transaxle, wheel assemblies, and
tyres are forced to work harder against
the load of the added weight. The engine
is required to operate at relatively higher
speeds and under greater loads. This
additional burden generates extra heat.
The trailer also adds considerably to
wind resistance, increasing the pulling
requirements.
TRAILER TOWING
CAUTION
Pulling a trailer improperly can
damage your vehicle and result in costly repairs not covered by yourwarranty. To pull a trailer correctly,
follow the advice in this section.
WARNING - Towing a trail-
er
If you don't use the correct equip-
ment and drive improperly, you can
lose control when you pull a trailer.
For example, if the trailer is too
heavy, the brakes may not work
well - or even at all. You and your
passengers could be seriously or
fatally injured. Pull a trailer only if
you have followed all the steps inthis section.
WARNING - Weight limits
Before towing, make sure the total
trailer weight, gross combination
weight, gross vehicle weight, grossaxle weight and trailer tongue loadare all within the limits.
