Seat cushion height (if equipped)
To change the height of the seat cushion,
push the lever that is located on the out-
side of the seat cushion upwards or
downwards.
• To lower the seat cushion, push thelever down several times.
To raise the seat cushion, pull the lever up several times. Lumbar support
(for driver’s seat, if equipped)
The lumbar support can be adjusted by
pressing the lumbar support switch on
the side of the drivers seat. Press the
front portion of the switch to increase
support, or the rear portion of the switch,
to decrease support.
Automatic adjustment (if equipped)
The front seat can be adjusted by using the control knob located on the outside of
the seat cushion. Before driving, adjustthe seat to the proper position so as to

Features of your vehicle
Power steering
Power steering uses energy from the
engine to assist you in steering the vehi-
cle. 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.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorised HYUNDAI
dealer.✽✽NOTICE
If the power steering drive belt breaks
or if the power steering pump malfunc-
tions, the steering effort will greatly
increase.
✽
✽ NOTICE
If the vehicle is parked for extended
periods outside in cold weather (below
-10°C/14°F), the power steering may
require increased effort when the engine
is first started. This is caused by
increased fluid viscosity due to the cold
weather and does not indicate a mal-
function.
When this happens, increase the engine
RPM by depressing accelerator until the
RPM reaches 1,500 rpm then release or
let the engine idle for two or three min-
utes to warm up the fluid.
Tilt steering
Tilt steering allows you to adjust the
steering wheel before you drive. You can
also raise it to give your legs more room
when you exit and enter the vehicle.
The steering wheel should be positioned
so that it is comfortable for you to drive,
whilst permitting you to see the instru-
ment panel warning lights and gauges.
STEERING WHEEL
CAUTION
Never hold the steering wheel
against a stop (extreme right or left
turn) for more than 5 seconds withthe engine running. Holding thesteering wheel for more than 5 sec-onds in either position may cause
damage to the power steeringpump.
WARNING
Never adjust the angle of the steering wheel whilst driving. You
may lose steering control and
cause severe personal injury,death or accidents.
After adjusting, push the steering wheel both up and down to be
certain it is locked in position.

ON
Press the engine start/stop button whilst
it is in the ACC position without depress-
ing the brake pedal.
The warning lights can be checked
before the engine is started. Do not leave
the button in the ON position if the engine
is not running to prevent the battery fromdischarging.
START
To start the engine, press the brake
pedal and press the engine start/stop
button with the shift lever in the P (Park)
or the N (Neutral) position. For your safe-
ty, start the engine with the shift lever in
the P (Park) position.
✽✽
NOTICE
 If you press the engine start/stop but- ton without depressing the brake
pedal, the engine does not start and
the engine start/stop button changes
as follow :
OFF →
→
ACC →→
ON →→
OFF
 If you leave the engine start/stop but-
ton in the ACC or the ON position for
a long time, the battery may be dis-
charged.
WARNING
Never press the engine start/stop button whilst the vehicle is in
motion. This would result in theengine turning off and loss of
power assist for the steering and
brakes, which may lead to loss of
directional control and braking
function, which could cause anaccident.
The anti-theft steering column lock is not a substitute for the
parking brake. Before leaving the
driver’s seat, always make sure
the shift lever is engaged in P
(Park),set the parking brake fully
and shut the engine off.
Unexpected and sudden vehicle
movement may occur if theseprecautions are not taken.
(Continued)
(Continued)
Never reach for the enginestart/stop button, or any other
controls through the steering
wheel whilst the vehicle is in
motion. The presence of yourhand or arm in this area could
cause a loss of vehicle control,
an accident and serious bodily
injury or death.
Do not place any movable objects around the driver’s seat as they
may move whilst driving, inter-
fere with the driver and lead to anaccident.

Driving your vehicle
Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces.In the event of brake failure
If service brakes fail to operate whilst the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
BRAKE SYSTEM WARNING
- Brakes
Do not drive with your foot rest- ing on the brake pedal. This will create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increasedstopping distances.
When descending a long or steep hill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brakeapplication will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
Wet brakes may impair the vehi- cle’s ability to safely slow down;
the vehicle may also pull to oneside when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
whilst maintaining a safe forward
speed until brake performancereturns to normal.
WARNING - Parking brake
Applying the parking brake whilst
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you mustuse the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.

Remember, your vehicle does not
require extended warm-up. After the
engine has started, allow the engine to
run for 10 to 20 seconds prior to plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
Don't "labour" or "over-rev" the engine. Labouring is driving too slowly in toohigh a gear resulting in the engine
bucking. If this happens, shift to a lower
gear. Over-revving is racing the engine
beyond its safe limit. This can be avoid-
ed by shifting at the recommended
speeds. Use your air conditioning sparingly.
The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorised
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING - Engine off dur-
ing motion
Never turn the engine off to coast
down hills or anytime the vehicle is
in motion. The power steering and
power brakes will not function
properly without the engine run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, turning off the ignition
whilst driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury ordeath.
