Low brake vacuum pressure warning
(2.0 TGDI engine only, if equipped)
If the warning light remains on, it may
indicate that the brake vacuum pump has
any problem. Therefore you should avoid
high speed driving or sudden stop, and
you should depress the brake pedal
deeper and harder than usual in braking.
Make sure to have the brake system
checked and repaired by an authorized
HYUNDAI dealer.
Low tire pressure telltale The low tire pressure telltale illuminates
when one or more of your tires is signifi-
cantly underinflated.
The low tire pressure telltale will illumi-
nate after it blinks for approximately one
minute when there is a problem with the
Tire Pressure Monitoring System.
If this occurs, have the system checked
by an authorized HYUNDAI dealer as
soon as possible.
For details, refer to the TPMS on chapter
6.
WARNING
- Low tire pres- sure
Significantly low tire pressure
makes the vehicle unstable and can
contribute to loss of vehicle control
and increased braking distances.
Continued driving on tires with low
pressure will cause the tires to
overheat and fail.
WARNING
- Safe stopping
 The TPMS cannot alert you to
severe and sudden tire damage
caused by external factors.
 If you feel any vehicle instability, immediately take your foot off the
accelerator, apply the brakes
gradually and with light force,
and slowly move to a safe posi-
tion off the road.
WARNING
 Continuous braking while drivingon steep or long downhill may
cause to descend the vacuum
level in brake booster for a time
and turn on the warning light. In
this case, shift down the trans-
mission. If the warning light illu-
minate continuously, stop the
vehicle in the safe location and
wait until the warning light goes
off.
 Driving the vehicle with a warn- ing light on is dangerous. If the
brake warning light remains on,
have the brakes checked and
repaired immediately by an
authorized HYUNDAI dealer.

5Your 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
miles (kilometers) you can get from a gal-
lon (liter) 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 "jack-rabbit" 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 pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing 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 tires. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
 Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tire 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 car
in accordance with the maintenance
schedule in section 7. If you drive your
car in severe conditions, more frequent
maintenance 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.ECONOMICAL OPERATION

5Hazardous driving conditions When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, follow
these suggestions:
 Drive cautiously and allow extra dis-
tance for braking.
 Avoid sudden in braking or steering.  If stalled in snow, mud, or sand, use
second gear. Accelerate slowly to
avoid spinning the drive wheels.
 Use sand, rock salt, tire chains, or other non-slip material under the drive
wheels to provide traction when stalled
in ice, snow, or mud.
Rocking the vehicle If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between 1st (First)
and R (Reverse) in vehicles equipped
with a manual transaxle or R (Reverse)
and any forward gear in vehicles
equipped with an automatic transaxle.
Do not race the engine, and spin the
wheels as little as possible. If you are still
stuck after a few tries, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating and possible dam-
age to the transaxle.
SPECIAL DRIVING CONDITIONS

WARNING -
ABS
Do not pump the brake pedal on a
vehicle equipped with ABS.
WARNING
- Downshifting
Downshifting with an automatic
transaxle, while driving on slippery
surfaces can cause an accident.
The sudden change in tire speed
could cause the tires to skid. Be
careful when downshifting on slip-
pery surfaces.
CAUTION
Prolonged rocking may causeengine over-heating, transaxle dam-age or failure, and tire damage.

Driving your vehicle
✽
✽NOTICEThe ESC system should be turned OFF
prior to rocking the vehicle.
Smooth corneringAvoid braking or gear changing in cor-
ners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration. If you follow
these suggestions, tire wear will be held
to a minimum.
Driving at night Because night driving presents more
hazards than driving in the daylight, here
are some important tips to remember:
 Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
WARNING
- Spinning tires
Do not spin the wheels, especially
at speeds more than 35 mph (56
km/h). Spinning the wheels at high
speeds when the vehicle is station-
ary could cause a tire to overheat
which could result in tire damage
that may injure bystanders.
OBH058035L
OMC035004
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle free
by moving it forward and backward.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle. During the rocking
operation the vehicle may suddenly
move forward or backward as it
becomes unstuck, causing injury
or damage to nearby people or
objects.

Driving your vehicle40
5 Adjust your mirrors to reduce the glare
from other driver's headlights.
 Keep your headlights clean and prop- erly aimed on vehicles not equipped
with the automatic headlight aiming
feature. Dirty or improperly aimed
headlights will make it much more diffi-
cult to see at night.
 Avoid staring directly at the headlights of oncoming vehicles. You could be
temporarily blinded, and it will take
several seconds for your eyes to read-
just to the darkness.
Driving in the rain Rain and wet roads can make driving
dangerous, especially if you’re not pre-
pared for the slick pavement. Here are a
few things to consider when driving in the
rain:
 A heavy rainfall will make it harder tosee and will increase the distance
needed to stop your vehicle, so slow
down.
 Keep your windshield wiping equip- ment in good shape. Replace your
windshield wiper blades when they
show signs of streaking or missing
areas on the windshield.
 If your tires are not in good condition, making a quick stop on wet pavement
can cause a skid and possibly lead to
an accident. Be sure your tires are in
good shape.
 Turn on your headlights to make it eas- ier for others to see you.
 Driving too fast through large puddles can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
 If you believe you may have gotten your brakes wet, apply them lightly
while driving until normal braking oper-
ation returns.
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 affected.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.

Driving your vehicle
Highway 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.

5More 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.
