Parking Brake & Brake
Fluid Warning Light
This warning light illuminates:
When the POWER button is in the
ON position.
- It illuminates for approximately 3
seconds.
- It remains on if the parking brake
is applied.
When the parking brake is applied.
When the brake fluid level in the
reservoir is low.
- If the warning light remains illumi-
nated when the parking brake is
released, check under the hood
to see if the fluid level in the brake
fluid reservoir is low.
If the brake fluid level in the reser-
voir is low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the vehicle turned off, check
the brake fluid level immediately
and add fluid as required (For more
details, refer to "Brake Fluid" in
chapter 7). After adding brake fluid,
check all brake components for fluid
leaks. If a brake fluid leak is found,
or if the warning light remains on, or
if the brakes do not operate proper-
ly, do not drive the vehicle. Have the
vehicle inspected by an authorized
HYUNDAI dealer.
Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the dual sys-
tems should fail.
With only one of the dual systems
working, more than normal pedal
travel and greater pedal pressure is
required to stop the vehicle.Also, the vehicle will not stop in as
short a distance with only a portion
of the brake system working.
Parking Brake & Brake Fluid
Warning Light
Driving the vehicle with a warn-
ing light ON is dangerous. If the
Parking Brake & Brake Fluid
Warning Light illuminates with
the parking brake released, it
indicates that the brake fluid
level is low.
If this occurs, have your vehicle
inspected by an authorized
HYUNDAI dealer.

Anti-lock Brake System
(ABS) Warning Light
This warning light illuminates:
When the POWER button is in the
ON position.
- It illuminates for approximately 3
seconds and then goes off.
When there is a malfunction with
the ABS (The normal braking sys-
tem will still be operational without
the assistance of the anti-lock
brake system).
If this occurs, have your vehicle
inspected by an authorized HYUNDAI
dealer.
Electronic
Brake Force
Distribution
(EBD) System Warning Light
When the ABS Warning and Parking
Brake Warning lamps are on simulta-
neously, it may indicate a problem
with the Electronic Brake Force
Distribution system.
If this occurs, have your vehicle
inspected by an authorized HYUNDAI
dealer.
Information - Electronic
Brake Force Distribution
(EBD) System Warning Light
When the ABS Warning Light is on or
both ABS and Parking Brake & Brake
Fluid Warning Lights are on, the
speedometer, odometer, or tripmeter
may not work. Also, the EPS Warning
Light may illuminate and the steering
effort may increase or decrease.
If this occurs, have your vehicle
inspected by an authorized HYUNDAI
dealer.i
Electronic Brake Force
Distribution (EBD) System
Warning Light
When both ABS and Parking
Brake & Brake Fluid Warning
Lights are on, the brake system
will not work normally and you
may experience an unexpected
and dangerous situation during
sudden braking.
If this occurs, avoid high speed
driving and abrupt braking.
Have your vehicle inspected by
an authorized HYUNDAI dealer.
WARNING

6-23
What to do in an emergency
6
Always follow these emergency tow-
ing precautions:
While depressing the brake pedal
shift to the N (Neutral) position and
turn the vehicle off. The POWER
button will be in the ACC position.
Release the parking brake.
Depress the brake pedal with more
force than normal since you will
have reduced braking perform-
ance.
More steering effort will be
required because the power steer-
ing system will be disabled.
Use a vehicle heavier than your
own to tow your vehicle.
The drivers of both vehicles should
communicate with each other fre-
quently.
Before emergency towing, check
that the hook is not broken or dam-
aged.
Fasten the towing cable or chain
securely to the hook.
Do not jerk the hook. Apply steady
and even force. Use a towing cable or chain less
than 16 feet (5 m) long. Attach a
white or red cloth (about 12 inch
(30 cm) wide) in the middle of the
cable or chain for easy visibility.
Drive carefully so the towing cable
or chain remains tight during towing.
Before towing, check the reduction
gear for fluid leaks under your vehi-
cle. If the reduction gear is leaking,
flatbed equipment or a towing dolly
must be used.Accelerate or decelerate the vehi-
cle in a slow and gradual manner
while maintaining tension on the
tow rope or chain to start or drive
the vehicle, otherwise tow hooks
and the vehicle may be damaged.
To avoid damage to your vehicle
and vehicle components when
towing:
Always pull straight ahead when
using the towing hooks. Do not
pull from the side or at a vertical
angle.
Do not use the towing hooks to
pull a vehicle out of mud, sand
or other conditions from which
the vehicle cannot be driven out
under its own power.
Limit the vehicle speed to
10 mph (15 km/h) and drive less
than 1 mile (1.5 km) when towing
to avoid serious damage to the
reduction gear.

The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized HYUNDAI dealer at the frequen-
cies indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
warranties and you may be charged
for labor, parts and lubricants used.Owner Maintenance Schedule
When you stop for charging:
• Check coolant level in the coolant
reservoir.
Check the windshield washer fluid
level.
Check for low or under-inflated
tires. Performing maintenance work
on a vehicle can be dangerous.
If you lack sufficient knowledge
and experience or the proper
tools and equipment to do the
work, have it done by an author-
ized HYUNDAI dealer.
ALWAYS follow these precau-
tions for performing mainte-
nance work:
•Park your vehicle on level
ground, shift to the P (Park)
position, apply the parking
brake, and place the POWER
button in the OFF position.
Block the tires (front and
back) to prevent the vehicle
from moving.
Remove loose clothing or jew-
elry that can become entan-
gled in moving parts.
Keep flames, sparks, or smok-
ing materials away from the
battery and related compo-
nents.
WARNING
Be careful when checking your
coolant level when the parts in
the motor compartment are hot.
This may result in coolant being
blown out of the opening and
cause serious burns and other
injuries.
WARNING

7-6
Maintenance
While operating your vehicle:
Check for vibrations in the steering
wheel. 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 traveling on smooth, level
road.
When decelerating with your vehi-
cle, listen and check for unusual
sounds, pulling to one side,
increased brake pedal travel or
"hard-to-push" brake pedal.
After driving your vehicle on a
regular basis check the follow-
ing:
Verify that the electronic parking
brake is engaging properly.
After you exit the vehicle check for
any signs of fluid leaks under your
vehicle (note that water dripping
from the air conditioning system is
normal).
At least monthly:
Check coolant level in the coolant
reservoir.
Check the operation of all exterior
lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all
four tires and check to see the tire
tread condition and if there are any
signs of abnormal wear or dam-
age.
Check for loose wheel lug nuts.
At least twice a year:
Check radiator, heater and air con-
ditioning hoses for leaks or dam-
age.
Check windshield 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 hood
hinges.
Lubricate door and hood locks and
latches.
Lubricate door rubber weather
strips.
Lubricate door checker.
Check the air conditioning system.
Inspect and lubricate reduction
gear linkage and controls.
Clean the battery and terminals.
Check the brake fluid level.
