ing such as driving on winding, moun-
tainous roads or high speed driving.

Driving your vehicle
Tire chains
Since the sidewalls of radial tires are
thinner, they can be damaged by mount-
ing some types of snow chains on them.
Therefore, the use of snow tires is rec-
ommended instead of snow chains. Do
not mount tire chains on vehicles
equipped with aluminum wheels; snow
chains may cause damage to the wheels.
If snow chains must be used, use wire-
type chains with a thickness of less than
12 mm (0.47 in). Damage to your vehicle
caused by improper snow chain use is
not covered by your vehicle manufactur-
ers warranty.
Install tire chains only on the rear tires.Chain installation
When installing chains, follow the manu-
facturer's instructions and mount them as
tightly as you can. Drive slowly with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until it stops. Remove the
chains as soon as you begin driving on
cleared roads.
CAUTION
• Make sure the snow chains are
the correct size and type for your
tires. Incorrect snow chains can
cause damage to the vehicle body
and suspension and may not be
covered by your vehicle manufac-
turer warranty. Also, the snow
chain connecting hooks may be
damaged from contacting vehicle
components causing the snow
chains to come loose from the
tire. Make sure the snow chains
are SAE class “S” certified.
• Always check chain installation
for proper mounting after driving
approximately 0.5 to 1 km (0.3 to
0.6 miles) to ensure safe mount-
ing. Retighten or remount the
chains if they are loose.
WARNING
- Mounting chains
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning flashers and place
a triangular emergency warning
device behind the vehicle if avail-
able. Always place the vehicle in P
(Park), apply the parking brake and
turn off the engine before installing
snow chains.

CAUTION
• Do not tow the vehicle with the
rear wheels on the ground as this
may cause damage to the vehicle.

ment. Use wheel lift or flatbed
equipment.
CAUTION
Failure to place the shift lever in N
(Neutral) may cause internal dam-
age to the transmission.
CAUTION
If the ECS malfunction indicator
illuminates when there is no air in
the suspension, the vehicle height
will be very lower, so do not drive to
protect the vehicle from the projec-
tions on the surface of the ground.

cle and have the system checked.

Maintenance
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake fluid
Check brake fluid level in the brake fluid
reservoir. The level should be between
“MIN” and “MAX” marks on the side of
the reservoir. Use only hydraulic brake
fluid conforming to DOT 3 or DOT 4
specification.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine off,
check for excessive free-play in the
steering wheel.
Check the linkage for bends or damage.
Check the dust boots and ball joints for
deterioration, cracks, or damage.
Replace any damaged parts.
Power steering pump, belt and
hoses
Check the power steering pump and
hoses for leakage and damage. Replace
any damaged or leaking parts immedi-
ately. Inspect the power steering belt (or
drive belt) for evidence of cuts, cracks,
excessive wear, oiliness and proper ten-
sion. Replace or adjust it if necessary.
Drive shafts and boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if nec-
essary, repack the grease.
Air conditioning refrigerant
(if equipped)
Check the air conditioning lines and con-
nections for leakage and damage.
Brake discs, pads, calipers and
rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for fluid
leakage.
For more information on checking the
pads or lining wear limit, refer to the
Hyundai web site.
