If You Have a Flat Tire While
Driving
If a tire goes flat while you are driving:
• Take your foot off the accelerator
pedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately or
attempt to pull off the road as this
may cause loss of vehicle control
resulting in an accident. When the
vehicle has slowed to such a speed
that it is safe to do so, brake carefully
and pull off the road. Drive off the
road as far as possible and park on
firm, level ground. If you are on a
divided highway, do not park in the
median area between the two traffic
lanes.
• When the vehicle is stopped, press the
hazard warning flasher button, shift
the gear to P (Park), apply the parking
brake, and press the Engine Start/Stop
button to the OFF position.
• Have all passengers get out of the
vehicle. Be sure they all get out on the
side of the vehicle that is away from
traffic.
• When changing a flat tire, follow the
instructions provided later in this
chapter.
IF THE ENGINE WILL NOT
START
• Be sure to shift the gear to N (Neutral)
or P (Park). The engine starts only
when the gear is in N (Neutral) or P
(Park).
• Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
See instructions for “Jump Starting”
provided in this chapter.
• Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, call an
authorized retailer of Genesis Branded
products for assistance.
NOTICE
Push or pull starting the vehicle may
cause the catalytic converter to
overload which can lead to damage to
the emission control system.
