2019 Hyundai Sonata Owner's Manual

When towing your vehicle in an
emergency without wheel dollies :
1. Place the ignition switch in theACC position.
2. Place the shift lever in N (Neutral).
3. Release the parking brake.Emergency Towing
(if equipped)
If towing is necessary, we recom-
mend you to have it done by an
authorized HYUNDAI dealer or a
commercial tow truck service. If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook at the rear of the vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. A
driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a
short distance and at low speeds.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
Failure to place the transmis-
sion shift lever in N (Neutral)
may cause internal damage to
the transmission.

6-38

Always follow these emergency tow-
ing precautions:
Place the ignition switch in theACC position so the steering wheel
is not locked.
Place the shift lever in N (Neutral).
Release the parking brake.
Depress the brake pedal with more force than normal since you will
have reduced braking perform-
ance.
More steering effort will be required because the power steer-
ing system will be disabled.
Use a vehicle heavier than your own to tow your vehicle.
The drivers of both vehicles should communicate with each other fre-
quently.
Before emergency towing, check that the hook is not broken or dam-
aged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply steady and even force. Use a towing cable or chain less
than 16 feet (5 m) long. Attach a
white or red cloth (about 12 inches
(30 cm) wide) in the middle of the
cable or chain for easy visibility.
Drive carefully so the towing cable or chain remains tight during tow-
ing.
Before towing, check the automat- ic transmission for fluid leaks under
your vehicle. If the automatic trans-
mission fluid is leaking, flatbed
equipment or a towing dolly must
be used.
ODH063025
To avoid damage to your vehicle
and vehicle components when
towing:
Always pull straight ahead
when using the towing hooks.
Do not pull from the side or at
a vertical angle.
Do not use the towing hooks
to pull a vehicle out of mud,
sand or other conditions from
which the vehicle cannot be
driven out under its own
power.
Limit the vehicle speed to 10
mph (15 km/h) and drive less
than 1 mile (1.5 km) when tow-
ing to avoid serious damage
to the automatic transmis-
sion.

You should retain documents that
show proper maintenance has been

mation to establish your compliance

ranties. Detailed warranty information is pro-
vided in your Owner's Handbook &

Precautions
Inadequate, incomplete or insuffi-
cient servicing may result in opera-
tional problems with your vehicle that
could lead to vehicle damage, an
accident, or personal injury. This
chapter provides instructions only for
the maintenance items that are easy
to perform. Several procedures can
be done only by an authorized
HYUNDAI dealer with special tools.
Your vehicle should not be modified
in any way. Such modifications may
adversely affect the performance,
safety or durability of your vehicle
and may, in addition, violate condi-
tions of the limited warranties cover-
ing the vehicle.
Certain modifications may also be in
violation of regulations established by
the U.S. Department of Transportation
and other federal or state agencies. Improper owner maintenance dur-
ing the warranty period may affect
warranty coverage. For details,
read the separate Owner's
Handbook & Warranty Information
booklet provided with the vehicle.
If you're unsure about any service
or maintenance procedure, have it
done by an authorized HYUNDAI
dealer.
