B740D02Y-AATOperation Tipso If the interior of the car is hot when you first
get in, open the windows for a few minutes
to expel the hot air.
o When you are using the air conditioning
system, keep all windows closed to keep hot
air out.
o When moving slowly, as in heavy traffic, shift
to a lower gear. This increases engine speed,
which in turn increases the speed of the air
conditioning compressor.
o On steep grades, turn the air conditioning off
to avoid the possibility of the engine over-
heating.
o During winter months or in periods when the
air conditioning is not used regularly, run the
air conditioning once every month for a few
minutes. This will help circulate the lubri-
cants and keep your system in peak oper-
ating condition.

will not start unless the clutch pedal is fully
depressed. On a manual transaxle equipped
vehicle that can be started without de-
pressing the clutch, there is the potential to
cause damage to the vehicle or injury to
someone inside or outside the vehicle as a
result of the forward or backward move-
ment of the vehicle that will occur if the
clutch is not depressed when the vehicle is

!GOOD BRAKING PRACTICESC130A01A-AAT
WARNING:
Nothing should be carried on top of the
shelf panel behind the rear seat. If there
were an accident or a sudden stop, such
objects could move forward and cause
damage to the vehicle or injure the occu-
pants.
o After being parked, check to be sure the
parking brake is not engaged and that the
parking brake indicator light is out before
driving away.
o Driving through water may get the brakes
wet. They can also get wet when the car is
washed. Wet brakes can be dangerous!
Your car will not stop as quickly if the brakes
are wet. Wet brakes may cause the car to
pull to one side. To dry the brakes, apply the
brakes lightly until the braking action returns
to normal, taking care to keep the car under
control at all times. If the braking action does
not return to normal, stop as soon as it is safe
to do so and call your Hyundai dealer for
assistance.o Don't coast down hills with the car out of gear.
This is extremely hazardous. Keep the car
in gear at all times, use the brakes to slow
down, then shift to a lower gear so that engine
braking will help you maintain a safe speed.
o Don't "ride" the brake pedal. Resting your
foot on the brake pedal while driving can be
dangerous because it can result in the brakes
overheating and losing their effectiveness. It
also increases the wear of the brake com-
ponents.
o If a tire goes flat while you are driving, apply
the brakes gently and keep the car pointed
straight ahead while you slow down. When
you are moving slowly enough for it to be safe
to do so, pull off the road and stop in a safe
place.
o If your car is equipped with an automatic
transaxle, don't let your car creep forward.
To avoid creeping forward, keep your foot
firmly on the brake pedal when the car is
stopped.
o Use caution when parking on a hill. Engage
the parking brake and place the gear selec-
tor lever in "P" (automatic transaxle) or in first
or reverse gear (manual transaxle). If your
car is facing downhill, turn the front wheels
into the curb to help keep the car from rolling.
If your car is facing uphill, turn the front
wheels away from the curb to help keep the
car from rolling. If there is no curb or if it is
required by other conditions to keep the car
from rolling, block the wheels.
C310D01NF-AATIndicators and WarningThe indicators should illuminate when the igni-
tion key is turned to ON or START but should
go out after three seconds.
If the indicators do not illuminate, or the ESC or
ESC-OFF indicator does not go out after 3
seconds, have the vehicle checked by an
authorized dealer.
Should there be any unusual operation of the
device while driving, the ESC-OFF indicator
illuminates as a warning.
If the ESC-OFF indicator illuminates, drive your
car to a safe place and stop the engine.
Then, start the engine again to check if the ESC-
OFF indicator goes out.
If the indicator remains lit even after the engine
has been started, have your car checked by an
authorized Hyundai dealer.
