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

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.

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.

inspected by an authorized HYUNDAI
dealer.

Warning Light
Driving the vehicle with a warn-
ing light ON is dangerous. If the

Maintenance
Owner Maintenance Schedule
When you stop for fuel:
• Check coolant level in the coolant
reservoir.
Check the windshield washer fluid
level.
Check for low or under-inflated
tires.
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 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 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
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.
