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.

Two labels on your driver’s door sill show
how much weight your vehicle was
designed to carry: the Tire and Loading
Information Label and the Certification
Label.
Before loading your vehicle, familiarize
yourself with the following terms for
determining your vehicle’s weight
ratings, from the vehicle’s specifications
and the Certification Label:
Base curb weight
This is the weight of the vehicle
including a full tank of fuel and all
standard equipment. It does not
include passengers, cargo, or optional
equipment.
Vehicle curb weight
This is the weight of your new vehicle
when you picked it up from your dealer
plus any aftermarket equipment.
Cargo weight
This figure includes all weight added to
the Base Curb Weight, including cargo
and optional equipment.
GAW (Gross Axle Weight)
This is the total weight placed on each
axle (front and rear) - including vehicle
curb weight and all payload.
GAWR (Gross Axle Weight Rating)
This is the maximum allowable weight
that can be carried by a single axle (front
or rear). These numbers are shown on
the Certification Label. The total load on
each axle must never exceed its GAWR.
GVW (Gross Vehicle Weight)
This is the Base Curb Weight plus actual
Cargo Weight plus passengers.
GVWR (Gross Vehicle Weight Rating)
This is the maximum allowable weight
of the fully loaded vehicle (including
all options, equipment, passengers
and cargo). The GVWR is shown on the
Certification Label located on the driver’s
door sill.
The Loading Information Label
ORS062057N
ORS062058N
The label located on the driver’s door
sill gives the original tire size, cold
tire pressures recommended for your
vehicle, the number of people that can
be in your vehicle and vehicle capacity
weight.
VEHICLE LOAD LIMIT

6-78
Driving Your Vehicle
Certification label
OBH059070
The certification label is located on the
driver's door sill at the center pillar and
shows the maximum allowable weight of
the fully loaded vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight of the vehicle,
all occupants, fuel and cargo.
This label also tells you the maximum
weight that can be supported by the
front and rear axles, called Gross Axle
Weight Rating (GAWR).
The total weight of the vehicle, including
all occupants, accessories, cargo, and
trailer tongue load must not exceed the
Gross Vehicle Weight Rating (GVWR) or
the Gross Axle Weight Rating (GAWR).
To find out the actual loads on your front
and rear axles, you need to go to a weigh
station and weigh your vehicle. Be sure
to spread out your load equally on both
sides of the centerline.
WARNING
Overloading

[Never exceed the GVWR for your
vehicle, the GAWR for either the front
or rear axle and vehicle capacity
weight. Exceeding these ratings
can affect your vehicle's handling
and braking ability, and cause an
accident.

[Do not overload your vehicle.
Overloading your vehicle can cause
heat buildup in your vehicle's tires
and possible tire failure, increased
stopping distances and poor vehicle
handling-all of which may result in a
crash.
NOTICE
Overloading your vehicle may cause
damage. Repairs would not be covered
by your warranty. Do not overload your
vehicle.
WARNING
If you carry items inside your vehicle
(for example, suitcases, tools, packages,
or anything else), they are moving as
fast as the vehicle. If you have to stop
or turn quickly, or if there is a crash, the
items will keep going and can cause
an injury if they strike the driver or a
passenger.

[Put items in the cargo area of your
vehicle. Try to spread the weight
evenly.

[Do not stack items like suitcases
inside the vehicle above the tops of
the seats.

[Do not leave an unsecured child
restraint in your vehicle.

[When you carry something inside the
vehicle, secure it.

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.
