What to do in an emergency
Towing Service
If emergency towing is necessary,
we recommend having it done by an
authorized retailer of Genesis
Branded products or a commercial
tow-truck service. Proper lifting and
towing procedures are necessary to
prevent damage to the vehicle. The
use of wheel dollies or flatbed is rec-
ommended.
When towing the vehicle by flatbed
equipment, secure wheels by using
chocks and tie-down straps (or soft
belts).Do not place straps over body panels
or through the wheels.
Do not lift the vehicle by the tow
fitting or body and chassis parts.
Otherwise the vehicle may be
damaged.
On AWD vehicles, your vehicle must
be towed with a wheel lift and dollies
or flatbed equipment with all the
wheels off the ground.
AWD vehicle should never be
towed with the wheels on the
ground. This can cause serious
damage to the transmission or the
AWD system.
On 2WD vehicles, it is acceptable to
tow the vehicle with the front wheels
on the ground (without dollies) and
the rear wheels off the ground.
If any of the loaded wheels or sus-
pension components are damaged
or the vehicle is being towed with the
rear wheels on the ground, use a
towing dolly under the rear wheels.
When being towed by a commercial
tow truck and wheel dollies are not
used, the rear of the vehicle should
always be lifted, not the front.

2. Remove the hole cover pressing the lower part of the cover on the
front or rear bumper.

Emergency Towing
If towing is necessary, we recommend
you have it done by an authorized
retailer of Genesis Branded products
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 tow-
ing 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 condition.
