2012 Hyundai Sonata warning light

527
Driving your vehicle
✽✽NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the anti-lock brake system
is functioning properly.
Even with the anti-lock brake system, your vehicle still requires sufficient
stopping distance. Always maintain a
safe distance from the vehicle in front
of you.
Always slow down when cornering. The anti-lock brake system cannot pre-
vent accidents resulting from exces-
sive speeds.
On loose or uneven road surfaces, operation of the anti-lock brake system
may result in a longer stopping dis-
tance than for vehicles equipped with a
conventional brake system.
✽✽ NOTICE
When you jump start your vehicle
because of a drained battery, the engine
may not run as smoothly and the ABS
warning light may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your
ABS is malfunctioning.
 Do not pump your brakes!
 Have the battery recharged before driving the vehicle.
W-78
CAUTION
If the ABS warning light is on and
stays on, you may have a problemwith the ABS. In this case, howev-er, your regular brakes will work normally.
The ABS warning light will stay on for approximately 3 seconds afterthe ignition switch is ON. Duringthat time, the ABS will go throughself-diagnosis and the light will go off if everything is normal. If thelight stays on, you may have aproblem with your ABS. Contactan authorised HYUNDAI dealer assoon as possible.
CAUTION
When you drive on a road having poor traction, such as an icy road,
and operate your brakes continu- ously, the ABS will be active con-tinuously and the ABS warninglight may illuminate. Pull your car
over to a safe place and stop theengine.
Restart the engine. If the ABS warning light is off, then your
ABS system is normal. Otherwise, you may have a prob-lem with the ABS. Contact an authorised HYUNDAI dealer as
soon as possible.

Hill-start assist control (HAC) (if equipped)
A vehicle has the tendency to slip back
on a steep hill when it starts to go after
stopping. The Hill-start Assist Control
(HAC) prevents the vehicle from slipping
back by operating the brakes automati-
cally for about 2 seconds. The brakes are
released when the accelerator pedal is
depressed or after about 2 seconds.
✽✽
NOTICE
 The HAC does not operate when the transaxle shift lever is in the P (Park)
or N (Neutral) position.
 The HAC activates even though the ESP(or ESC) is off but it does not acti-
vate when the ESP(or ESC) has mal-
functioned.
Good braking practices After parking the vehicle, check to be
sure the parking brake is not engaged
and that the parking brake indicator
light is out before driving away.
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
an authorised HYUNDAI dealer for
assistance.
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.
WARNING
The HAC is activated only for about
2 seconds, so when the vehicle is
starting off always depress theaccelerator pedal.
WARNING
Whenever leaving vehicle or parking, always set the parking
brake as far as possible and fully
engage the vehicle's transaxle
into the park position. Vehicles
not fully engaged in park with the
parking brake set are at risk for
moving inadvertently and injur-
ing yourself or others.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the car whichcan injure occupants or pedestri-ans.

➀ CRUISE indicator
➁ SET indicator
The cruise control system allows you to
program the vehicle to maintain a con-stant speed without pressing the acceler-ator pedal. This system is designed to function
above approximately 40 km/h (25 mph).
✽✽ NOTICE
During normal cruise control operation,
when the SET switch is activated or
reactivated after applying the brakes,
the cruise control will energize after
approximately 3 seconds. This delay is
normal.
CRUISE CONTROL SYSTEM (IF EQUIPPED)
WARNING
If the cruise control is left on, (CRUISE indicator light in the
instrument cluster illuminated)
the cruise control can be activat-
ed unintentionally. Keep the
cruise control system off
(CRUISE indicator light OFF)
when the cruise control is not in
use, to avoid inadvertently set-ting a speed.
Use the cruise control system only when travelling on open
highways in good weather.
Do not use the cruise control when it may not be safe to keep
the car at a constant speed, for
instance, driving in heavy or
varying traffic, or on slippery
(rainy, icy or snow-covered) or
winding roads or over 6% up-hill
or down-hill roads.
Pay particular attention to the driving conditions whenever
using the cruise control system.
Be careful when driving downhill using the cruise control system,
which may increase the vehiclespeed.

Driving your vehicle
Remember, your vehicle does notrequire 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.

Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, followthese suggestions:
Drive cautiously and allow extra dis-
tance for braking.
Avoid sudden movements in braking or steering.
When braking with non-ABS brakes pump the brake pedal with a light up-
and-down motion until the vehicle isstopped. If stalled in snow, mud, or sand, use
second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, tyre chains, or other non-slip material under the drive
wheels to provide traction when stalled
in ice, snow, or mud. Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between 1st (First)
and R (Reverse) in vehicles equipped
with a manual transaxle or R (Reverse)
and any forward gear in vehicles
equipped with an automatic transaxle.
Do not race the engine, and spin the
wheels as little as possible. If you are still
stuck after a few tries, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating and possible dam-
age to the transaxle.
SPECIAL DRIVING CONDITIONS
1JBB3302
WARNING -
ABS
Do not pump the brake pedal on a
vehicle equipped with ABS.
WARNING - Downshifting
Downshifting with an automatic
transaxle, whilst driving on slipperysurfaces can cause an accident.
The sudden change in tyre speed
could cause the tyres to skid. Be
careful when downshifting on slip-
pery surfaces.
CAUTION
Prolonged rocking may cause engine over-heating, transaxle dam-age or failure, and tyre damage.

543
Driving your vehicle
✽✽NOTICE
The ESP (or ESC) system should be
turned OFF prior to rocking the vehicle.
Smooth cornering
Avoid braking or gear changing in cor-
ners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration. If you follow
these suggestions, tyre wear will be held
to a minimum. Driving at night
Because night driving presents more
hazards than driving in the daylight, here
are some important tips to remember:
Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
WARNING - Spinning tyres
Do not spin the wheels, especially at speeds more than 56 km/h (35
mph). Spinning the wheels at high
speeds when the vehicle is station-
ary could cause a tyre to overheat
which could result in tyre damage
that may injure bystanders.
OMC035004
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle free
by moving it forward and backward.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle. During the rocking
operation the vehicle may suddenly
move forward of backward as it
becomes unstuck, causing injury
or damage to nearby people orobjects.
