Driving your vehicle

ABS is an electronic braking system
that helps prevent a braking skid.
ABS allows the driver to steer and
brake at the same time.
Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your
brake pressure and do not try to
pump your brakes. Depress your
brake pedal as hard as possible.
When you apply your brakes under
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This is
normal and it means your ABS is
active.
ABS does not reduce the time or dis-
tance it takes to stop the vehicle.
Always maintain a safe distance from
the vehicle in front of you.
ABS will not prevent a skid that
results from sudden changes in
direction, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather con-
ditions.ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing wheel movement can still cause
your vehicle to veer into oncoming
traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake sys-
tem may result in a longer stopping
distance than for vehicles equipped
with a conventional brake system.
The ABS warning light ( ) will stay
on for several seconds after the igni-
tion switch is in the ON position.
During that time, the ABS will go
through self-diagnosis and the light
will go off if everything is normal. If
the light stays on, you may have a
problem with your ABS. Contact an
authorized HYUNDAI dealer as soon
as possible(Continued)
Drive your vehicle at reduced
speeds during the following
conditions:
Rough, gravel or snow-cov-
ered roads.
On roads where the road sur-
face is pitted or has different
surface height.
Tire chains are installed on
your vehicle.
The safety features of an ABS
or ESC equipped vehicle should
not be tested by high speed
driving or cornering. This could
endanger the safety of yourself
or others.

Information
When you jump start your vehicle
because of a drained battery, the ABS
warning light ( ) may turn on at the
same time. This happens because of
the low battery voltage. It does not
mean your ABS is malfunctioning.
Have the battery recharged before
driving the vehicle.
i
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, contact your
HYUNDAI dealer as soon as
possible.When you drive on a road hav-
ing poor traction, such as an icy
road, and apply your brakes
continuously, the ABS will be
active continuously and the
ABS warning light ( ) may
illuminate. Pull your car over to
a safe place and turn the engine
off.
Restart the engine. If the ABS
warning light is off, then your
ABS system is normal.
Otherwise, you may have a
problem with your ABS system.
Contact an authorized HYUNDAI
dealer as soon as possible.
CAUTIONWARNING

Driving your vehicle
To prevent damage to the trans-
mission:
Do not allow wheel(s) of one axle to spin excessively while
the ESC, ABS, and brake warn-
ing lights are displayed. The
repairs would not be covered by
the vehicle warranty. Reduce
engine power and do not spin
the wheel(s) excessively while
these lights are displayed.
When operating the vehicle on a dynamometer, ensure the ESC is
turned off (ESC OFF light illumi-
nated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
prevents the vehicle from rolling
backwards when starting a vehicle
from a stop on a hill. The system
operates the brakes automatically for
approximately 2 seconds and releas-
es the brake when the accelerator
pedal is depressed or after 2 sec-
onds. The HAC does not operate when
the shift lever is in P (Park) or N
(Neutral)
The HAC activates even though the ESC (Electronic Stability
Control) is off but does not acti-
vate when the ESC has malfunc-
tioned.
NOTICE

NOTICE
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC acti-
vates only for approximately 2
seconds.

Smart Cruise Control will betemporarily canceled when:
Canceled manually
Depressing the brake pedal.
Pressing the CANCEL button
located on the steering wheel.
The Smart Cruise Control turns off

LCD display turns off.
The CRUISE indicator is illuminated
continuously. Canceled automatically
The driver's door is opened.

(Neutral), R (Reverse) or P (Park).
The EPB (Electronic Parking Brake) is applied.
The vehicle speed is over 120 mph (190 km/h)
The ESC (Electronic Stability Control), TCS (Traction Control
System) or ABS is operating.
The ESC is turned off.
The AEB (Automatic Emergency Btaking) system is operating.
The radar or the cover is dirty or blocked with foreign matter.
The engine speed is over 7000 rpm.
The SCC system has malfunctioned.
When the vehicle is stopped for more than 5 minutes.
The driver starts driving by pushing the toggle switch up (RES +) or
down (SET -) or depressing the
accelerator pedal, approximately 3
seconds after the vehicle is
stopped by the Smart Cruise
Control System with no other vehi-
cle ahead. The driver starts driving by pushing
the toggle switch up (RES +) or
down (SET -) or depressing the
accelerator pedal, after stopping
the vehicle with a vehicle stopped
far away in front.
The accelerator pedal is continu- ously depressed for more than 5
minutes.
Each of these actions will cancel
the Smart Cruise Control opera-
tion. (The Set Speed and Vehicle-
to-Vehicle Distance on the LCD
display will go off.)
In a condition the Smart Cruise
Control is canceled automatically,
the Smart Cruise Control will not
resume even though the RES+ or
SET- toggle switch is pushed. Also,
the EPB will be applied when the

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 and
wheels 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 serious
accident.
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 on
the 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 check
the pressure of the other tires
on your vehicle.

Wheel Alignment and Tire
Balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
Improper wheel weights can dam-
age your vehicle’s aluminum
wheels. Use only approved wheel
weights.
Tire Replacement
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1/16 inch (1.6 mm) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.
NOTICE
OLMB073027
Tread wear indicatorTo reduce the risk of DEATH or
SERIOUS INJURY:
Replace tires that are worn,
show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering control, and
traction.
Always replace tires with the
same size as each tire that
was originally supplied with
this vehicle. Using tires and
wheels 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 serious
accident.(Continued)
