Driving up or down hills

[Driving uphill
-Before starting off, check if it is
possible to drive uphill.
-Drive as straight as possible.

[Driving downhill
-Do not change gear while driving
downhill. Select gear before driving
downhill.
-Drive slowly using engine braking
while driving downhill.
-Drive straight as possible.
WARNING
Exercise extreme caution driving up or
down steep hills. The vehicle may flip
over depending on the grade, terrain,
water and mud conditions.
WARNING
Do not drive across the contour of steep
hills. A slight change in the wheel angle
can destabilize the vehicle, or a stable
vehicle may lose stability if the vehicle
stops its forward motion. Your vehicle
may roll over and lead to a serious injury
or death.
Emergency Precautions
Tires
When replacing tires, be sure to equip
all four tires with the same size, type,
tread pattern, brand and load-carrying
capacity.
WARNING
Do not use tire and wheel with different
size and type from the one originally
installed on your vehicle. It can affect
the safety and performance of your
vehicle, which could lead to steering
failure or rollover causing serious injury.
In an emergency situation, a compact
spare tire may be used. But, do not use
the compact spare tire continuously.
Repair or replace the original tire as
soon as possible to avoid failure of the
differential or AWD system.

Driving Your Vehicle
SPECIAL DRIVING CONDITIONS
Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water, snow,
ice, mud and sand, take the following
precautions:

[Drive cautiously and maintain a longer
braking distance.

[Avoid abrupt braking or steering.

[When your vehicle is stuck in
snow, mud, or sand, use second
gear. Accelerate slowly to avoid
unnecessary wheel spin.

[Put sand, rock salt, tire chains or other
non-slip materials under the wheels to
provide additional traction while the
vehicle becomes stuck in ice, snow,
or mud.
WARNING
Downshifting with an automatic
transmission while driving on slippery
surfaces can cause an accident. The
sudden change in tire speed could
cause the tires to skid. Be careful when
downshifting on slippery surfaces.
Rocking the Vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between R (Reverse)
and a forward gear.
Try to avoid spinning the wheels, and do
not race the engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on the
accelerator pedal while the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes a
rocking motion that may free the vehicle.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
in the tires can increase very quickly.
If the tires become damaged, a tire
blow out or tire explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire or
other damage. Try to avoid spinning the
wheels as much as possible to prevent
overheating of either the tires or the
engine. DO NOT allow the vehicle to
spin the wheels above 35 mph
(56 km/h).

6-68
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.

06
The severe weather conditions of winter
quickly wear out tires and cause other
problems. To minimize winter driving
problems, you should take the following
suggestions:
Snow or Icy Conditions
You need to keep sufficient distance
between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid
acceleration, sudden brake applications,
and sharp turns are potentially
very hazardous practices. During
deceleration, use engine braking to the
fullest extent. Sudden brake applications
on snowy or icy roads may cause the
vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires or to
install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to carry
include tire chains, tow straps or chains,
a flashlight, emergency flares, sand, a
shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket,
etc.
Summer tires

[Summer tires are used to maximize
the driving performance on dry roads.

[If the temperature is below 45°F or
you are driving on snowy or icy roads,
the summer tires lose their brake
performance and traction as the tire
grip weakens significantly.

[If the temperature is below 45°F or
you are driving on snowy or icy roads,
mount snow tires or all-season tires
of the same size with your vehicle's
standard tire for safe driving. Both
snow and all-season tires have M+S
markings.

[When using the M+S tires, use tires
with the same tread produced by the
same manufacturer for safe driving.

[When driving with the M+S tires with
the lower maximum allowable speed
than that of the vehicle's standard
summer tire, be careful not to exceed
the speed allowed for the M+S tires.

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.

Tire chains
ORS061025L
Since the sidewalls on some radial tires
are thinner than other types of tires,
they may be damaged by mounting
certain types of tire chains on them.
Do not mount tire chains on vehicles
equipped with aluminum wheels; if
possible use AutoSock® (fabric snow
chain or similar). Install AutoSock® after
reviewing the instructions provided
with AutoSock®. Damage to your vehicle
caused by improper use of fabric snow
chains are not covered by your vehicle
manufacturer's warranty.
Information
AutoSock® is a Registered trademark of
AutoSock.
WARNING
The use of AutoSock® (fabric snow
chain) may adversely affect vehicle
handling:

[Drive less than 20 mph (30 km/h)
or the AutoSock® manufacturer’s
recommended speed limit,
whichever is lower.

[Drive carefully and avoid bumps,
holes, sharp turns, and other road
hazards, which may cause the
vehicle to bounce.

[Avoid sharp turns or locked wheel
braking.
Disabling Rear Wheel Steering system to
install snow chains
ORS061036L
If the Rear Wheel Steering system is
applied, disable the system to protect the
vehicle when snow chains are installed.

Driving Your Vehicle
NOTICE
If you drive without disabling the
Rear Wheel Steering system in the
infotainment system after installing
snow chains, the snow chains can
damage your vehicle’s body or chassis
parts. When you hear the snow chain
hitting the vehicle, stop the vehicle and
check whether the snow chains are
installed properly and whether the Rear
Wheel Steering system is disabled.
Information

[Install AutoSock® (fabric snow chain)
only in pairs and on the rear tires.
It should be noted that installing
AutoSock (fabric snow chain) on the
tires will provide a greater driving
force, but will not prevent side skids.

[Do not install studded tires without
first checking local, state and municipal
regulations for possible restrictions
against their use.
Chain Installation
When installing AutoSock® (fabric
snow chain), follow the manufacturer's
instructions and mount them as tightly
as possible. Drive slowly (less than 20
mph (30 km/h)) with AutoSock® installed.
If you hear the fabric snow chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the AutoSock® as soon as you begin
driving on cleared roads.
When mounting AutoSock®, park the
vehicle on level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emergency
warning device behind the vehicle (if
available).
Always place the vehicle in P (Park),
apply the parking brake and turn off the
engine before installing tire chains.
NOTICE
When using AutoSock® (fabric snow
chain):

[Wrong size fabric snow chains or
improperly installed fabric snow
chains can damage your vehicle's
brake lines, suspension, body and
wheels.

[If you hear noise caused by fabric
snow chains contacting the body,
retighten the fabric snow chains to
prevent contact with the vehicle
body.

[To prevent body damage, retighten
the fabric snow chains after driving
0.3~0.6 miles (0.5~1.0 km).

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.

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.
