Moving up a steep grade from a stand-
ing startTo move up a steep grade from a stand-
ing start, depress the brake pedal, shift
the shift lever to D (Drive). Depress the
accelerator gradually while releasing the
service brakes.
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.
WARNING
 Always buckle-up! In a collision, an unbelted occupant is signifi-
cantly more likely to be seriously
injured or killed than a properly
belted occupant.
 Avoid high speeds when corner- ing or turning.
 Do not make quick steering wheel movements, such as sharp
lane changes or fast, sharp turns.
 The risk of rollover is greatly increased if you lose control of
your vehicle at highway speeds.
 Loss of control often occurs if two or more wheels drop off the
roadway and the driver over-
steers to reenter the roadway.
 In the event your vehicle leaves the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
 Never exceed posted speed lim- its.

To decrease the cruising speed:Follow either of these procedures:
 Pushthe SET- switch and hold it. Your
vehicle will gradually slow down.
Release the switch at the speed you
want to maintain.
 Push the SET- switch and release it immediately. The cruising speed will
decrease 1.0 mph (1.6 km/h) each
time the SET- switch is operated in this
manner.
To temporarily accelerate with the
cruise control on:If you want to speed up temporarily when
the cruise control is on, depress the
accelerator pedal. Increased speed will
not interfere with cruise control operation
or change the set speed.
To return to the set speed, take your foot
off the accelerator.
To cancel cruise control, do one
of the following: Press the brake pedal.
 Press the clutch pedal with a manualtransaxle.

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
1JBB3302
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.

Use high quality ethylene glycol
coolantYour 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 cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule in section 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.Check battery and cablesWinter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station.
Change to "winter weight" oil if
necessaryIn some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.Check spark plugs and ignition
systemInspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING
- Tire chains
 The use of chains may adversely
affect vehicle handling.
 Do not exceed 20 mph (30 km/h) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
 Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
 Avoid sharp turns or locked- wheel braking.
CAUTION
 Chains that are the wrong size or improperly installed can damageyour vehicle's brake lines, sus-pension, body and wheels.
 Stop driving and retighten the chains any time you hear themhitting the vehicle.

Certification 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 can
cause 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.
 Using heavier suspension com- ponents to get added durabilitymight not change your weightratings. Ask your dealer to helpyou load your vehicle the rightway.

What to do in an emergency
You may not be able identify a low
tire by simply looking at it. Always
use a good quality tire pressure
gauge to measure the tire's inflation
pressure. Please note that a tire that
is hot (from being driven) will have a
higher pressure measurement than a
tire that is cold.
A cold tire means the vehicle has
been sitting for 3 hours and driven for
less than 1 mile (1.6 km) in that 3
hour period.
Allow the tire to cool before measur-
ing the inflation pressure. Always be
sure the tire is cold before inflating to
the recommended pressure.This device complies with Part 15
of the FCC rules.
Operation is subject to the following
two conditions:
1.This device may not cause harmful
interference, and
2.This device must accept any inter- ference received, including inter-
ference that may cause undesired
operation.
CAUTION
Do not use any tire sealant ifyour vehicle is equipped with aTire Pressure MonitoringSystem. The liquid sealant candamage the tire pressure sen-sors.
WARNING
- Protecting TPMS
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS) com-
ponents may interfere with the
system's ability to warn the driv-
er of low tire pressure condi-
tions and/or TPMS malfunctions.
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS) com-
ponents may void the warranty
for that portion of the vehicle.
WARNING
- TPMS
 The TPMS cannot alert you to severe and sudden tire dam-
age caused by external fac-
tors such as nails or road
debris.
 If you feel any vehicle instabil- ity, immediately take your foot
off the accelerator, apply the
brakes gradually and with
light force, and slowly move to
a safe position off the road.
WARNING
Changes or modifications not
expressly approved by the party
responsible for compliance
could void the user’s authority
to operate the equipment.
