Do not scrape ice off the mirrorface; this may damage the sur-
face of the glass.
If the mirror is jammed with ice, do not adjust the mirror by
force. Use an approved spray
de-icer (not radiator antifreeze)
spray, or a sponge or soft cloth
with very warm water, or move
the vehicle to a warm place and
allow the ice to melt. Adjusting the rearview mirrors:
1. Press either the L (left side) or R
(right side) button (1) to select the
rearview mirror you would like to
adjust.
2. Use the mirror adjustment control to position the selected mirror up,
down, left or right.
3. After adjustment, put the button into neutral (centre) position to
prevent inadvertent adjustment. The mirrors stop moving when
they reach the maximum adjust-
ing angles, but the motor contin-
ues to operate whilst the switch
is pressed. Do not press the
switch longer than necessary,
the motor may be damaged.
Do not attempt to adjust the out- side rearview mirror by hand or
the motor may be damaged.

What to do in an emergency
1. Pull off the road and stop as soon as it is safe to do so.
2. Shift to P (Park) and set the park- ing brake. If the air conditioning is
on, turn it off.
3. If coolant is running out under the vehicle or steam is coming out
from the bonnet, stop the vehicle.
Do not open the bonnet until the
coolant has stopped running or
the steaming has stopped. If there
is no visible loss of coolant and no
steam, leave the vehicle running
and check to be sure the cooling
fan is operating. If the fan is not
running, turn the vehicle off.
4. Check for coolant leaking from the radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop). 5. If coolant is leaking out, turn off
the vehicle immediately and we
recommend that you call a
HYUNDAI authorised repairer for
assistance.
6. If you cannot find the cause of the overheating, wait until the radiator
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark. 7. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call a
HYUNDAI authorised repairer for
assistance.
Serious loss of coolant indi- cates there is a leak in the cool-
ing system and we recommend
that the system be checked by a
HYUNDAI authorised repairer.
When overheating from low coolant, suddenly adding coolant
may cause damages in the motor
compartments. To prevent dam-
age, add coolant slowly in small
quantities.

Do not remove the coolant cap
when the radiator is hot. This
can allow coolant to blow out of
the opening and cause serious
burns.

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.

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.

MaintenanceThe electric motor for the cooling fan
is controlled by coolant temperature,
refrigerant pressure and vehicle
speed. As the coolant temperature
decreases, the electric motor will
automatically shut off. This is a nor-
mal condition.
Never remove the
coolant cap or the
drain plug whilst the
radiator is hot. Hot
coolant and steam
may blow out under pressure,
causing serious injury.

WARNING
OAEE076002
The electric motor for
the cooling fan may
continue to operate
or start up when the
vehicle is not operat-
ing and can cause serious
injury.
Keep hands, clothing and tools
away from the rotating fan blades
of the cooling fan.
WARNING (Continued)
Turn the vehicle off and wait
until the parts in the motor com-
partment cools down. Use
extreme care when removing
the coolant cap. Wrap a thick
towel around it, and turn it
counterclockwise slowly to the
first stop. Step back whilst the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.
