Parking Brake & BrakeFluid Warning Light
This warning light illuminates:
When the POWER button is in the
ON position.
- It illuminates for approximately 3seconds.
- 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 illuminateswith the parking brake released, it
indicates the brake fluid level in
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
information, refer to "Brake
Fluid" in chapter 7) . After adding
brake fluid, check all brake compo-
nents for fluid leaks. If a brake fluid
leak is found, or if the warning light
remains on, or if the brakes do not
operate properly, 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.

Use approved window washeranti-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 brakefreeze
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.
Do not let ice and snow accu-mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.
Don't place foreign objects ormaterials in the motor compart-ment
Placement of foreign object or mate-
rials which prevent cooling of the
vehicle, in the motor compartment,
may cause a failure. The manufactur-
er is not responsible for the damage
caused by such placement.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.

What to do in an emergency
6
Emergency Towing
If towing is necessary, we recom-
mend you have it done by an author-
ized HYUNDAI dealer or a commer-
cial tow truck service.
If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook at the front (or rear) of the
vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. A
driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a
short distance and at low speeds.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.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.

Maintenance
Owner Maintenance Schedule
When you stop for fuel:
• Check coolant level in the coolantreservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires.
While 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 traveling 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 brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
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.
