Maintenance
Whilst operating your vehicle:
Check for vibrations in the steeringwheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly turns slightly or “pulls” to one side
when travelling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the operation of your reduction gear
occurs, check the reduction gear
fluid level.
Check the reduction gear P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the coolantreservoir.
Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flashers.
Check the inflation pressures of all tyres including the spare for tyres
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
At least twice a year: (i.e., every Spring and Fall)
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windscreen washer spray and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
Check headlamp alignment.
Check the seat belts for wear and function.
At least once a year:
Clean body and door drain holes.
Lubricate door hinges and bonnethinges.
Lubricate door and bonnet locks and latches.
Lubricate door rubber weather strips.
Check the air conditioning system.
Inspect and lubricate reduction gear linkage and controls.
Clean the battery and terminals.
Check the brake fluid level.

Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Reduction gear fluid
The reduction gear fluid should be
inspected according to the intervals
specified in the maintenance sched-
ule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX
marks on the side of the reservoir.
Use only hydraulic brake fluid con-
forming to DOT 3 or DOT 4 specifi-
cation.
Brake discs, pads, calipers
and rotors
Check the pads, the disc, and the
rotor for any excessive wear-out.
Inspect calipers for any fluid leakage.
For more information on checking
the pads or lining wear limit, refer to
the HYUNDAI web site.
(http://ser
vice.hyundai-motor.com)
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and the
hybrid system off, check for exces-
sive free-play in the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage.
Replace any damaged parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and damage.

Tyre care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tyre
inflation pressures and stay within the
load limits and weight distribution rec-
ommended for your vehicle.
(Continued)Replace tyres that are worn,
show uneven wear, or are dam-
aged. Worn tyres can cause
loss of braking effectiveness,
steering control, or traction.
ALWAYS replace tyres with
the same size as each tyre
that was originally supplied
with this vehicle. Using tyres
and wheels other than the rec-
ommended 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.
Tyre 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 tyres monthly for
proper inflation as well as
wear and damage.
The recommended cold tyre
pressure for your vehicle can
be found in this manual and on
the tyre label located on the
driver’s side centre pillar.
Always use a tyre pressure
gauge to measure tyre pres-
sure. Tyres with too much or
too little pressure wear
unevenly causing poor han-
dling.
Check the pressure of the
spare every time you check
the pressure of the other tyres
on your vehicle.

Maintenance
Wheel alignment and tyre bal-
ance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tyre
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tyre
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 aluminium
wheels. Use only approved wheel
weights.
Tyre replacement
If the tyre is worn evenly, a tread
wear indicator will appear as a solid
band across the tread. This shows
there is less than 1/16 in. (1.6 mm) of
tread left on the tyre. Replace the
tyre when this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tyre.

Tread wear indicatorTo reduce the risk of DEATH or
SERIOUS INJURY:
Replace tyres that are worn,
show uneven wear, or are
damaged. Worn tyres can
cause loss of braking effec-
tiveness, steering control, and

mended sizes could cause

Maintenance
vehicle, pay particular attention to
the components under the fenders
and other areas that are hidden
from view. Do a thorough job; just
dampening the accumulated mud
rather than washing it away will
accelerate corrosion rather than
prevent it. Water under high pres-
sure and steam are particularly
effective in removing accumulated
mud and corrosive materials.
When cleaning lower door panels, rocker panels and frame members,
be sure that drain holes are kept
open so that moisture can escape
and not be trapped inside to accel-
erate corrosion.Keep your garage dry
Don’t park your vehicle in a damp,
poorly ventilated garage. This cre-
ates a favorable environment for cor-
rosion. This is particularly true if you
wash your vehicle in the garage or
drive it into the garage when it is still
wet or covered with snow, ice or
mud. Even a heated garage can con-
tribute to corrosion unless it is well
ventilated so moisture is dispersed.
Keep paint and trim in good condition
Scratches or chips in the finish
should be covered with "touch-up"
paint as soon as possible to reduce
the possibility of corrosion. If bare
metal is showing through, the atten-
tion of a qualified body and paint
shop is recommended.
Bird droppings are highly corrosive
and may damage painted surfaces in
just a few hours. Always remove bird
droppings as soon as possible.
Interior care
Interior general precautions
Prevent caustic solutions such as
perfume and cosmetic oil, from con-
tacting the interior parts because
they may cause damage or dis-
colouration. If they do contact the
interior parts, wipe them off immedi-
ately. See the instructions for the
proper way to clean vinyl.
Never allow water or other liq-uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.
When cleaning leather products (steering wheel, seats etc.), use
neutral detergents or low alco-
hol content solutions. If you use
high alcohol content solutions
or acid/ alkaline detergents, the
colour of the leather may fade or
the surface may get stripped off.
