Driving Your Vehicle
Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:

[Slow down and allow extra following
distance. A heavy rainfall makes
it harder to see and increases the
distance needed to stop your vehicle.

[Turn OFF your Smart Cruise Control

[Replace your windshield wiper blades
when they show signs of streaking or
missing areas on the windshield.

[Be sure your tires have enough tread.
If your tires do not have enough depth
of tire tread, making a quick stop on
wet pavement can cause a skid and
possibly lead to an accident. See “Tire
Tread” section in chapter 9.

[Turn on your headlights to make it
easier for others to see you.

[Driving too fast through large puddles
can affect your brakes. If you must go
through puddles, try to drive through
them slowly.

[If you believe your brakes may be wet,
apply them lightly while driving until
normal braking operation returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the water.
The best advice is SLOW DOWN when
the road is wet.
The risk of hydroplaning increases as the
depth of tire tread decreases, refer to
“Tire Tread” section in chapter 9.
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or fail the
braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

Snow tires
WARNING
Snow tires should be equivalent in size and type to the vehicle’s standard tires.
Otherwise, the safety and handling of your vehicle may be adversely affected.
We recommend that you use snow tires when road temperature is below 45°F (7°C).
Refer to the below chart, and mount the recommended snow tire for your vehicle.
Standard tire Recommended snow tire
Tire size Wheel size Tire size Wheel size
245/45R20 8.5J x 20 245/45R20 8.5J x 20
275/40R20 9.5J x 20 275/40R20 9.5J x 20
245/40R21 8.5J x 21 245/40R21 8.5J x 21
275/35R21 9.5J x 21 275/35R21 9.5J x 21
If you mount snow tires on your vehicle, make sure to use the same Inflation pressure
as the original tires. Mount snow tires on all four wheels to balance your vehicle’s
handling in all weather conditions. The traction provided by snow tires on dry roads
may not be as high as your vehicle’s original equipment tires. Check with the tire dealer
for maximum speed recommendations.

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.

Tire Pressure Monitoring System
WARNING
Over-inflation or under-inflation can
reduce tire life, adversely affect vehicle
handling, and lead to sudden tire failure
that may cause loss of vehicle control
resulting in an accident.
Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label. (If your
vehicle has tires of a different size than
the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on
a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating
properly. The TPMS malfunction
indicator is combined with the low
tire pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that
prevent the TPMS from functioning
properly.
Always check the TPMS malfunction
telltale after replacing one or more tires
or wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
NOTICE
If any of the below happens, have
the system checked by an authorized
retailer of Genesis Branded products.
1. The Low Tire Pressure Telltale/ TPMS
Malfunction Indicator does not
illuminate for 3 seconds when the
Engine Start/Stop button is pressed
to the ON position or when the
engine is running.
2. The TPMS Malfunction Indicator
remains illuminated after blinking for
approximately 1 minute.
3. The Low Tire Pressure Position
Telltale remains illuminated.

Emergency Situations
Low Tire Pressure
Warning Light
Low Tire Pressure Position and
Tire Pressure Telltale
ORS081029LORS081029L
When the tire pressure monitoring
system warning indicators are
illuminated and a warning message
displayed on the cluster LCD display,
one or more of your tires is significantly
under-inflated. The Low Tire Pressure
Position Telltale will indicate which
tire is significantly underinflated by
illuminating the corresponding position
light.
If either telltale illuminates, immediately
reduce your speed, avoid hard cornering
and anticipate increased stopping
distances. You should stop and check
your tires as soon as possible. Inflate the
tires to the proper pressure as indicated
on the vehicle’s placard or tire inflation
pressure label located on the driver’s
side center pillar outer panel.If you cannot reach a service station or
if the tire cannot hold the newly added
air, replace the low pressure tire with the
spare tire.
The Low Tire Pressure LCD position
indicator will remain on and the TPMS
Malfunction Indicator may blink for one
minute and then remain illuminated until
you have the low pressure tire repaired
and replaced on the vehicle.
CAUTION
In winter or cold weather, the Low Tire
Pressure Telltale may be illuminated if
the tire pressure was adjusted to the
recommended tire inflation pressure
in warm weather. It does not mean
your TPMS is malfunctioning because
the decreased temperature leads to a
proportional lowering of tire pressure.
When you drive your vehicle from a
warm area to a cold area or from a cold
area to a warm area, or the outside
temperature is greatly higher or lower,
you should check the tire inflation
pressure and adjust the tires to the
recommended tire inflation pressure.
WARNING
Low pressure damage
Significantly low tire pressure makes
the vehicle unstable and can contribute
to loss of vehicle control and increased
braking distances.
Continued driving on low pressure tires
can cause the tires to overheat and fail.

TPMS (Tire Pressure
Monitoring System)
Malfunction Indicator
The TPMS Malfunction Indicator
will illuminate after it blinks for
approximately one minute when there
is a problem with the Tire Pressure
Monitoring System.
Have the system checked by an
authorized retailer of Genesis Branded
products as soon as possible.
NOTICE
If there is a malfunction with the TPMS,
the Low Tire Pressure Position Telltale
will not be displayed even though the
vehicle has an under-inflated tire.
NOTICE
The TPMS Malfunction Indicator may
illuminate after blinking for one minute
if the vehicle is near electric power
supply cables or radio transmitters
such as police stations, government
and public offices, broadcasting
stations, military installations, airports,
transmitting towers, etc.
Additionally, the TPMS Malfunction
Indicator may illuminate if snow chains
are used or electronic devices such as
computers, chargers, remote starters,
navigation, etc. This may interfere with
normal operation of the TPMS.
Changing a Tire with TPMS
If you have a flat tire, the Low Tire
Pressure and Position telltales will come
on. Have the flat tire repaired by an
authorized retailer of Genesis Branded
products as soon as possible or replace
the flat tire with the spare tire.
NOTICE
It is recommended that you do not use a
puncture-repairing agent not approved
by an authorized retailer of Genesis
Branded products to repair and/or
inflate a low pressure tire. Tire sealant
not approved by an authorized retailer
of Genesis Branded products may
damage the tire pressure sensor.
The spare tire does not come with a
tire pressure monitoring sensor. When
the low pressure tire or the flat tire is
replaced with the spare tire, the Low
Tire Pressure LCD position indicator will
remain on. Also, the TPMS Malfunction
Indicator will illuminate after blinking
for one minute if the vehicle is driven
at speed above 15.5 mph (25 km/h) for
approximately 20 minutes.
Once the original wheel equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pressure
and reinstalled on the vehicle, the
Low Tire Pressure Telltale and TPMS
Malfunction Indicator will go off within a
few minutes of driving.
