Features of your vehicle
Electric power steering (if equipped)
Power steering uses the motor to assist
you in steering the vehicle. If the engine
is off or if the power steering system
becomes inoperative, the vehicle may
still be steered, but it will require
increased steering effort.
The motor driven power steering is con-
trolled by the power steering control unit
which senses the steering wheel torque
and vehicle speed to command the
motor.
The steering wheel becomes heavier as
the vehicle’s speed increases and
becomes lighter as the vehicle’s speed
decreases for better control of the steer-ing wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by a HYUNDAI authorised
repairer.✽✽NOTICE
The following symptoms may occur dur- ing normal vehicle operation:

rised repairer.

needs attention. When releasing the
parking brake, the brake system warning
light should go off. The fuel warning light
will stay on if the fuel level is low.

Parking brake & brake
fluid warning
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 it towed to a HYUNDAI autho-
rised repairer for a brake system
inspection and necessary repairs. Your vehicle is equipped with dual-diago-
nal braking systems. This means you still
have braking on two wheels even if one
of the dual systems should fail. With only
one of the dual systems working, more
than normal pedal travel and greaterpedal 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
whilst 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 switchis in the ON position.
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 a HYUNDAI authorised
repairer.
CAUTION
If the light comes on continuously after adding the engine oil and trav-
elling approximately 30 miles (50km), take your vehicle to your near-est HYUNDAI authorised repairer and have the system checked.
Even if this light doesn't come onafter the engine has started, theengine oil should be checked andsupplied periodically.
