Parking brake & brake fluid
warning light
Parking brake warning
This light is illuminated when the parking
brake is applied with the ignition switch in
the START or ON position. The warning
light should go off when the parking
brake is released.
Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check the
brake fluid level immediately and add
fluid as required. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are
found, the warning light remains on or
the brakes do not operate properly.
Have the vehicle towed to any author-
ized HYUNDAI dealer for a brake sys-
tem inspection and necessary repairs.Your vehicle is equipped with a dual-
diagonal braking system. This means you
still have braking on two wheels even if
one of the brake circuits is damaged or
malfunctions. With only one of the circuits
working, more than normal pedal travel
and greater pedal pressure are required
to stop the car. Also, the car will not stop
in as short a distance with only a portion
of the brake system working. If the
brakes fail while you are driving, shift to a
lower gear for additional engine braking
and stop the car as soon as it is safe to
do so.
To check bulb operation, check whether
the parking brake and brake fluid warning
light illuminates when the ignition switch
is in the ON position.
Low tire pressure
telltale
The low tire pressure telltale illuminates
when one or more of your tires is signifi-
cantly underinflated.
Inflate your tires to the correct inflation
pressure.
The low tire pressure telltale will illumi-
nate after it blinks for approximately one
minute when there is a problem with the
Tire Pressure Monitoring System.
If this occurs, have the system checked
by an authorized HYUNDAI dealer as
soon as possible.
For details, refer to the TPMS on chapter 6.
WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorized HYUNDAI
dealer.
WARNING - Low tire pres-
sure
Significantly low tire pressure
makes the vehicle unstable and can
contribute to loss of vehicle control
and increased braking distances.
Continued driving on tires with low
pressure will cause the tires to
overheat and fail.

vehicle is in motion:
1. Drive to the nearest safe location.
2. With the engine off, check the genera-
tor drive belt for looseness or break-
age.
3. If the belt is adjusted properly, a prob-
lem exists somewhere in the electrical
charging system. Have an authorized
HYUNDAI dealer correct the problem
as soon as possible.

Malfunction Indicator Light illumi-
nated may cause damage to the
emission control systems which
could effect drivability and/or fuel
economy.
If the Malfunction Indicator Light
illuminates or blinks, potential
catalytic converter damage is
possible. This could result in loss
of engine power. Have the Engine
Control System inspected as

Drinking and driving is dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Driving
while under the influence of drugs
is as dangerous or more dangerous
than driving drunk.
You are much more likely to have a
serious accident if you drink or
take drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-
er who has been drinking or taking
drugs. Choose a designated driver
or call a cab.
WARNING
When you intend to park or stop
the vehicle with the engine on, be
careful not to depress the accel-
erator pedal for a long period of
time. It may overheat the engine
or exhaust system and cause fire.
When you make a sudden stop or
turn the steering wheel rapidly,
loose objects may drop on the
floor and it could interfere with
the operation of the foot pedals,
possibly causing an accident.
Keep all things in the vehicle
safely stored.
If you do not focus on driving, it
may cause an accident. Be care-
ful when operating what may dis-
turb driving such as audio or
heater. It is the responsibility of
the driver to always drive safely.
WARNING
