Emergency Towing
„„Front
ONE1081018
„„Rear
ONE1081019
If towing is necessary, have it done by
an authorized HYUNDAI dealer or a
commercial tow truck service.
If a towing service is not available in
an emergency, your vehicle may be
temporarily towed using a cable or chain
secured to the emergency towing hook
at the front (or 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 working condition.
CAUTION
The driver must be in the vehicle for
steering and braking operations when
the vehicle is being towed. Passengers
other than the driver must not be in the
vehicle.
Always follow these emergency towing
precautions: • Press the Start/Stop button to the
ACC position so the steering wheel is
not locked.
• Shift the gear to N (Neutral).
• Release the parking brake.
• Depress the brake pedal with more
force than normal as you will have
reduced braking performance.
• More steering effort will be required
because the power steering 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
frequently.
• Before emergency towing, check that
the hook is not broken or damaged.
• Fasten the towing cable or chain
securely to the hook.
• Do not jerk the hook. Apply steady
and even force.

Battery Recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery. • If the battery becomes discharged
over a short time (because, for
example, the headlamps or interior
lights were left on while the vehicle
was not in use), recharge it by slow
charging (trickle) for 10 hours.
• If the battery gradually discharges
because of high electrical load while
the vehicle is being used, recharge it
at 20-30A for two hours.
