2019 HYUNDAI SONATA HYBRID stop start

F9
Introduction
Fuel Additives
HYUNDAI recommends that you use good quality gasolines treated with
detergent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.These gasolines will help the engine
run cleaner and enhance performance
of the Emission Control System. For
more information on TOP TIER
Detergent Gasoline, please go to the
website (www
.toptiergas.com).
For customers who do not use TOP
Tier Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, addi-
tives that you can buy separately
may be added to the gasoline. If TOP
TIER Detergent Gasoline is not avail-
able, one bottle of additive added to
the fuel tank at every 12,000 km(7,500 miles) or 12 months is recom-mended.
Additives are available from your
authorized HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
Observe all regulations regarding registration and insurance.
Determine that acceptable fuel is available. No special break-in period is needed.
By following a few simple precautions
for the first 1,000 km (600 miles) you
may add to the performance, econo-
my and life of your vehicle.
Do not race the engine.
While driving, keep your engine
speed (rpm, or revolutions per
minute) between 2,000 rpm and
4,000 rpm.
Do not maintain a single speed for long periods of time, either fast or
slow. Varying engine speed is need-
ed to properly break-in the engine.
Avoid hard stops, except in emer- gencies, to allow the brakes to seat
properly.

Hybrid Vehicle
HHEEVV (( HH YY BBRRIIDD EE LLEE CCTT RR IICC VV EEHH IICC LLEE )) SS YY SSTT EEMM
The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the electric motor for power. The elec-
tric motor is run by a high-voltage HEV battery.
Depending on the driving conditions, the HEV computer selectively operates between the engine and the electric motor
or even both at the same time.
Fuel efficiency increases when the engine is off at idle, or when the vehicle is driven by the electric motor with the HEV
battery.
The HEV battery charge must be maintained, so at times the engine will come on even at idle to act as a generator.
Charging also occurs when decelerating or by regenerative braking.

5. Remove any dust on the charging
connector and charging inlet.
6. Hold the charging connector han- dle. Then, insert it into the charg-
ing inlet, until you hear a click
sound. If it is not fully connected, a
bad connection between thecharging connector and the charg-
ing terminals may cause a fire. 7. Check if the charging cable con-
nection indicator of the high volt-
age battery in the instrument clus-
ter is turned ON.
Charging does not occur when the
indicator is OFF. When the charg-ing connector is not connected
properly, reconnect the charging
cable to charge. Information
 The charging is in progress only with the shift lever is in P (Park).
Charging the battery with the
Engine Start/Stop button in the
ACC position is possible. However,
it may discharge the 12-V battery.
Thus, if possible, charge the battery
with the Engine Start/Stop button in
the OFF position.
 Moving the shift lever from P (Park) to R (Reverse)/N(Neutral)/D (Drive)
stops the charging process.
To restart the charging process,
move the shift lever to P (Park),
press the Engine Start/Stop button
to the OFF position, and disconnect
the charging cable. Then, connect
the charging cable.

age battery in the instrument
cluster is turned ON.
Charging does not occur when

To restart the charging process,
move the shift lever to P (Park),
press the Engine Start/Stop button
to the OFF position, and disconnect
the charging cable. Then, connect
the charging cable and restart the
vehicle again. 11. After charging has started, the
estimated charging time is dis-
played on the instrument cluster
for about 1 minute. It is also dis-
played, when the driver’s door isopened with charging in
progress. When scheduled charg-ing is set, the estimated charging
time is displayed as “--".

Starting the vehicle
1. Carry the smart key or leave it
inside the vehicle.
2. Make sure the parking brake is firmly applied.
3. Place the shift lever in P (Park). With the shift lever in N (Neutral),
you cannot start the vehicle.
4. Depress the brake pedal.
5. Press the Engine Start/Stop but- ton. If the hybrid system starts, the
" " indicator will come on and a
double chime can be heard.
Whether the engine is cold or warm, it should be started without
depressing the accelerator.
After following the start proce-
dures, " " indicator on the
instrument cluster will turn on.
For more information, please checkChapter 5. ECONOMICAL and SAFE OPERA- TION of Hybrid system
Drive smoothly. Accelerate at a
moderate rate and maintain a
steady cruising speed. Do not
make "jack-rabbit" starts. Do not
race between stoplights.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear out.
The regenerative brake generates energy when the vehicle deceler-
ates.
When the hybrid battery power is low, the hybrid system automatical-
ly recharges the hybrid battery.
When the engine is running with the shift lever in N (Neutral), the
hybrid system cannot generate
electricity. The hybrid battery can-
not recharge with the shift lever in N
(Neutral). Information
In the hybrid system, the engine auto-
matically runs and stops. When the
hybrid system operates, the " "
indicator is illuminated.
In the following situation, the engine
may operate automatically.
- When the engine is ready to run
- When the hybrid battery is being charged
- Depending on the temperature con- dition of the hybrid battery
i
To avoid serious injury, turn off
hybrid system and be sure " "
indicator is off before working
under hood. Engine may start
unexpectedly.

H29
Check Hybrid system. Do notstart engine.
This warning message is displayed
when the hybrid battery power
(SOC) level is low. A warning chime
will sound until the problem is solved.
In this case, have your vehicle
inspected by an authorized HYUNDAI
dealer.
Stop vehicle and check powersupply
This warning message is displayed
when a failure occurs in the powersupply system.
In this case, park the vehicle in a
safe location and tow your vehicle to
the nearest authorized HYUNDAI
dealer and have the vehicle inspect-ed.
Park with engine On to charge battery
This warning message is displayed
when the hybrid battery power
(SOC) level is low.
In this case, park the vehicle in a
safe location and wait until the hybrid
battery is charged.
You can increase the hybrid battery
charging rate by holding the acceler-
ator pedal to the floor with transmis-
sion in P. The engine will rev high but
it will be limited for charging purpose
when you hold the pedal to the floor.

❈ Example of a deceleration event is
going down an extended hill, slow-
ing down approaching a toll booth,and approaching reduced speed
zones.

Press the Engine Start/Stop button and put the shift lever in P(Park). In the
User Settings Mode, select Driving Assist, Coasting Guide, and then On to
turn on the system. Cancel the selection of coasting guide to turn off the sys-
tem. For the explanation of the system, press and hold the [OK] button.

To activate the system, take the following procedures. Enter your destination
information on the navigation and select the driving route. Select the ECO
mode in the Integrated Driving Control System. Then, satisfy the following.
- The driving speed should be between 60 km/h (37 mph) and 160 km/h (99 mph). ❈The operating speed may vary due to difference between instrument clus-
ter and navigation effected by tire inflation level.
