Driving your vehicle
5Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all four
tires and wheels are the same
size. Never drive the vehicle with
different sized wheels and tires
installed.
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 the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.

Good Braking Practices
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop
as quickly if the brakes are wet. Wet
brakes may cause the vehicle to pull
to one side.To dry the brakes, apply the brakes
lightly until the braking action returns
to normal. If the braking action does
not return to normal, stop as soon as
it is safe to do so and call an author-
ized HYUNDAI dealer for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, but
constant pedal pressure can result in
the brakes overheating, brake wear,
and possibly even brake failure.
If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the vehicle 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 location.
Keep your foot firmly on the brake
pedal when the vehicle is stopped to
prevent the vehicle from rolling for-
ward. Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Shift
to the P (Park) position, then
apply the parking brake, and
place the POWER button in the
OFF position.
Vehicles parked with the park-
ing brake not applied or not
fully engaged may roll inadver-
tently and may cause injury to
the driver and others. ALWAYS
apply the parking brake before
exiting the vehicle.

you. Do not entirely rely on
the systems. Always pay
attention, while driving, for
your safety.
- When using the Cruise

manually adjust the distance
to other vehicles by depress-
ing the brake pedal. The sys-
tem does not automatically
adjust the distance to vehi-
cles in front of you.
Take the following precautions :
Always set the vehicle speed
under the speed limit on the
road that you are driving.
If Smart Cruise Control is left
on, (cruise ( ) indi-
cator light in the instrument
cluster is illuminated) Smart

use, to avoid inadvertently
setting a speed.
Use Smart Cruise Control sys-
tem only when traveling on
open highways in good
weather.

safe to keep the vehicle at a
constant speed:
- When driving in heavy traffic
or when traffic conditions
make it difficult to drive at a
constant speed
- When driving on rainy, icy, or
snow-covered roads
- When driving on a steep

The use of tire chains may
adversely affect vehicle han-
dling:
Drive less than 20 mph (30
km/h) or the chain manufac-
turer's recommended speed
limit, whichever 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.
WARNING Information
• Install tire chains only in pairs and
on the front tires. It should be noted
that installing tire chains on the
tires will provide a greater driving
force, but will not prevent side
skids.
• Do not install studded tires without
first checking local, state and
municipal regulations for possible
restrictions against their use.
Chain Installation
When installing tire chains, follow the
manufacturer's instructions and
mount them as tightly possible. Drive
slowly (less than 20 mph (30 km/h))
with chains installed. If you hear the
chains 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.i

5-140
Driving your vehicle
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 driving
0.3~0.6 miles (0.5~1.0 km).
Do not use tire chains on vehi-
cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 0.47 in
(12 mm) thick to prevent damage
to the chain's connection.
Winter Precautions
Change to "winter weight" oil if
necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.
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 instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized HYUNDAI dealer and
most auto parts outlets. Do not use
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
Do not 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 temporarily while
you shift to P (Park) and block the
rear wheels so the car cannot roll.
Then release the parking brake.
