2021 HYUNDAI SONATA HYBRID warning lights

Emergency situations
7-2
ODN8079001
The hazard warning flasher serves as
a warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle.
It should be used whenever emergency
repairs are being made or when the
vehicle is stopped near the edge of a
roadway.
To turn the hazard warning flasher on
or off, press the hazard warning flasher
button with the Engine Start/Stop button
in any position. The button is located in
the center fascia panel. All turn signal
lights will flash simultaneously.
• The hazard warning flasher operates
regardless of whether your vehicle is
in the READY state or not.
• The turn signals do not work when the
hazard flasher is on.
If the Engine Stalls While Driving
• Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
• Turn on your hazard warning flasher.
• Try to start the engine again. If your
vehicle will not start, contact an
authorized HYUNDAI dealer.
If the Engine Stalls at a Crossroad
or Crossing
If the engine stalls at a crossroads or
crossing, if safe to do so, shift the gear to
N (Neutral) and then push the vehicle to
a safe location.

WHILE DRIVING

Maintenance
8-6
While operating your vehicle:
• Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
• Check for vibrations in the steering
wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.
• 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 transmission occurs,
check the transmission fluid level.
• Check the automatic transmission 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 engine
coolant reservoir.
• Check the operation of all exterior
lights, including the stoplights, 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.
At least twice a year: (i.e., every
Spring and Autumn)
• Check radiator, heater and air
conditioning hoses for leaks or
damage.
• Check windshield washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.
• Check headlamp alignment.
• Check muffler, exhaust pipes, shields
and clamps.
• Check the seat belts for wear and
function.
At least once a year:
• Clean body and door drain holes.
• Lubricate door hinges and hood
hinges.
• Lubricate door and hood locks and
latches.
• Lubricate door rubber weather strips.
• Check the air conditioning system.
