Driving your vehicle
Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all fourtires and wheels are the same
size. Never drive the vehicle with
different sized wheels and tiresinstalled.
ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud by temporarily
stopping operation of the ESC to
maintain wheel torque.
To turn ESC off while driving, press
the ESC OFF button while driving on
a flat road surface. Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and parking brake
warning lights are displayed.
The repairs would not be cov-
ered by the vehicle warranty.
Reduce vehicle power and do
not spin the wheel(s) excessive-
ly while these lights are dis-
played.
When operating the vehicle on a dynamometer, make sure theESC is turned off (ESC OFF lightilluminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.

different sized tires and wheelsinstalled.
Hill-Start Assist Control (HAC) (if equipped)
A vehicle has the tendency to slide
backwards on a steep slope, before
depressing the accelerator after a
stop. The HAC prevents the vehicle
from sliding backwards by automati-
cally operating the brake systems for
about 2 seconds. The brake systemsare automatically released, when the
accelerator pedal is depressed.
Information
 The HAC does not operate when the gear is in P (Park) or N (Neutral).
 The HAC activates even when the ESC (Electronic Stability Control) is
off. However, it does not activate,
when the ESC does not normally
operate.
i
NOTICE
If ESC indicator light ( ) or
EPS warning light ( ) stays
on or blinks, your vehicle may
have a malfunction with the
VSM system. When the warninglight illuminates we recommend
that the vehicle be checked by
an authorized HYUNDAI dealer
as soon as possible.
WARNING
The HAC is activated only for
about 2 seconds, so alwaysdepress the accelerator pedal
to begin driving upwards after astop.

Driving your vehicle
The severe weather conditions of
winter quickly wear out tires and
cause other problems. To minimize
winter driving problems, you should
take the following suggestions:Information
Information for Snow Tires and Tire
Chains in the national language
(Bulgarian, Hungarian, Icelandic,
Polish) is provided in the Appendix.
Snow or icy conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. 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 applications on snowy or icy
roads may cause the vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires. Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, tow straps
or chains, a flashlight, emergency
flares, sand, a shovel, jumper cables,
a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tires
If you mount snow tires on your vehi-
cle, make sure to use 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.
The traction provided by snow tires
on dry roads may not be as high as
your vehicle's original equipment
tires. Check with the tire dealer for
maximum speed recommendations.
Information
Do not install studded tires without first
checking local and municipal regula-
tions for possible restrictions against
their use.

Snow tires should be equivalent
in size and type to the vehicle's
standard tires. Otherwise, the
safety and handling of your
vehicle may be adversely affect-ed.

Chain Installation
When installing tire chains, follow the
manufacturer's instructions and
mount them as tightly possible. Drive
slowly (less than 30 km/h (20 mph))
with chains installed. If you hear thechains contacting the body or chas-
sis, stop and tighten them. If they still
make contact, slow down until the
noise stops. Remove the tire chains
as soon as you begin driving on
cleared roads.
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning Flasher and place a
triangular emergency warning device
behind the vehicle (if available).
Always place the vehicle in P (Park),
apply the parking brake and turn off
the vehicle before installing snow
chains.When using tire chains:
Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Use SAE "S" class or wire chains.
If you hear noise caused by chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage, retighten the chains after driving0.5~1.0 km (0.3~0.6 miles).
Do not use tire chains on vehi- cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 12 mm (0.47 in) thick to prevent damage
to the chain's connection.
Winter precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type ofcoolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolantin 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.

What to do in an emergency
Tire pressure monitoring sys- tem
Each tire 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 yourtires 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 toindicate when the system is not
operating properly. The TPMS mal-function indicator is combined with
the low tire pressure telltale. Whenthe 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 illu-
minated, the system may not be able
to detect or signal low tire pressure
as intended. TPMS malfunctions may
occur for a variety of reasons, includ-ing the installation of replacement or
alternate tires or wheels on the vehi-
cle that prevent the TPMS from func-
tioning properly.
Always check the TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle toensure 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.

Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within the
load limits and weight distribution rec-
ommended for your vehicle.
(Continued)Replace tires that are worn,
show uneven wear, or are dam-
aged. Worn tires can cause
loss of braking effectiveness,
steering) control, or traction.
ALWAYS replace tires with the
same size as each tire that
was originally supplied with
this vehicle. Using tires andwheels other than the recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle’s Anti-Lock Brake System(ABS) resulting in a seriousaccident.
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
Inspect your tires monthly for
proper inflation as well as
wear and damage.
The recommended cold tire
pressure for your vehicle can
be found in this manual and onthe tire label located on the dri-
ver’s side center pillar. Always
use a tire pressure gauge to
measure tire pressure. Tires
with too much or too little
pressure wear unevenly caus-ing poor handling.
Check the pressure of the
spare every time you checkthe pressure of the other tires
on your vehicle.

Maintenance
All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side center pillar.
Recommended cold tire infla- tion pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold tires” means the
vehicle has not been driven for at
least three hours or driven less than1.6 km (one mile).
Warm tires normally exceed recom-
mended cold tire pressures by 28 to
41 kPa (4 to 6 psi). Do not release air
from warm tires to adjust the pres-sure or the tires will be under-inflat-
ed. For recommended inflation pres-
sure, refer to “Tire and Wheels” inchapter 8.Recommended pressures must
be maintained for the best ride,
vehicle handling, and minimum
tire wear.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
could result in loss of vehicle
control resulting in an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation andother tire failures that can result
in the loss of vehicle control
resulting in an accident. This
risk is much higher on hot days
and when driving for long peri-ods at high speeds.

Maintenance
Tire rotation
To equalize tread wear, HYUNDAI recommends that the tires be rotated
every 12,000 km (7,500 miles) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness (proper torque is 11~13 kgf·m [79~94 lbf·ft]).Disc brake pads should be inspected
for wear whenever tires are rotated. Information
The outside and inside of the unsym-
metrical tire is distinguishable. When
installing an unsymmetrical tire, be
sure to install the side marked "out-
side" face the outside. If the side
marked "inside" is installed on the
outside, it will have a bad effect on
vehicle performance.

■ With a full-size spare tire (if equipped)
■Without a spare tire
Do not use the compact spare
tire for tire rotation.
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause
unusual handling characteris-
tics that may cause loss of
vehicle control resulting in anaccident.
