Winter Precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 9. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be checked by
an authorized retailer of Genesis Branded
products or in a service station.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity. In
addition, replace the engine oil and filter
if it is close to the next maintenance
interval. Fresh engine oil ensures
optimum engine operation during the
winter months. For further information,
refer to chapter 2. When you are not sure
about a type of winter weight oil, consult
an authorized retailer of Genesis Branded
products.Check spark plugs and ignition system
Inspect the spark plugs, as specified in
chapter 9. If necessary, replace them.
Also check all ignition wirings and
components for any cracks, wear-out,
and damage.
To prevent locks from freezing
To prevent the locks from being frozen,
spray approved de-icing fluid or glycerin
into key holes. When a lock opening is
already covered with ice, spray approved
de-icing fluid over the ice to remove it.
When an internal part of a lock freezes,
try to thaw it with a heated key. Carefully
use the heated key to avoid an injury.
Use approved window washer anti-
freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as specified
on the window washer container.
Window washer anti-freeze solution is
available from an authorized retailer of
Genesis Branded products, and most
vehicle accessory outlets. Do not use
engine coolant or other types of anti-
freeze solution, to prevent any damage
to the vehicle paint.
Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. When there is the risk that your
parking brake may freeze, temporarily
apply it with the gear in P (Park). Also,
block the rear wheels in advance, so the
vehicle may not roll. Then, release the
parking brake.

Emergency Situations
When driving with the compact spare tire
mounted to your vehicle:
• Check the tire pressure after installing
the compact spare tire. The compact
spare tire should be inflated to 60 psi
(420 kPa).
• Do not take this vehicle through
an automatic car wash while the
compact spare tire is installed.
• Do not use the compact spare tire on
any other vehicle because this tire
has been designed especially for your
vehicle.
• The compact spare tire’s tread life is
shorter than a regular tire. Inspect
your compact spare tire regularly and
replace worn compact spare tires with
the same size and design, mounted on
the same wheel.
• Do not use more than one compact
spare tire at a time.
• Do not tow a trailer while the compact
spare tire is installed.
Information
When the original tire and wheel are
repaired and reinstalled on the vehicle, the
wheel bolt torque must be set correctly.
The correct wheel bolt tightening torque is
101~116 lbf·ft (14~16 kgf·m).
NOTICE
To prevent damaging the compact
spare tire and your vehicle:
• Drive slowly enough for the road
conditions to avoid all hazards, such
as a potholes or debris.
• Avoid driving over obstacles. The
compact spare tire diameter is
smaller than the diameter of a
conventional tire and reduces the
ground clearance approximately
1 in. (25 mm).
• Do not use tire chains on the
compact spare tire. Because of the
smaller size, a tire chain will not fit
properly.
• Do not use the compact spare tire
on any other wheels, nor should
standard tires, snow tires, wheel
covers or trim rings be used with the
compact spare wheel.
• Do not suddenly accelerate or
decelerate 0 ~ 25 mph (0 ~ 40 km/h)
in any driving mode. It may cause
leakage of transfer oil.

Follow Normal Maintenance Schedule if the vehicle is usually operated where none of the
following conditions apply. If any of the following conditions apply, you must follow the
Maintenance Under Severe Usage Conditions.

[Repeated driving short distance of less than 5 miles (8 km) in normal temperature or less
than 10 miles (16 km) in freezing temperature

[Extensive engine idling or low speed driving for long distances

[Driving on rough, dusty, muddy, unpaved, graveled or salt-spread roads

[Driving as a patrol car, taxi, other commercial use of vehicle towing

[Frequently driving under high speed or rapid acceleration/deceleration

[Frequently driving in stop-and-go conditions

[Engine oil usage which is not recommended (Mineral type, Semi-synthetic, Lower grade
spec, etc.)
If your vehicle is operated under the above conditions, you should inspect, replace or refill more
frequently than the following Normal Maintenance Schedule. After the periods or distance
shown in the chart, continue to follow the semi-synthetic, prescribed maintenance intervals.
NOTICE
After 10 years or 100,000 miles, we recommend to use severe maintenance schedule.
Information

[As it is normal for engine oil to be consumed during driving, the engine oil level should be checked
on regular basis.

[The engine oil change interval for normal operating conditions is based on the use of the
recommended engine specification. If the recommended engine oil specification is not used, then
replace the engine oil according to the maintenance schedule under severe operating conditions.

-If the deterioration of the engine oil increases depending on the driver’s driving severity,
the remaining oil life alert appears on the instrument cluster before the normal engine oil

Branded product.
-Oil Life Management System works when the recommended engine oil is used. So, if

-Always reset the remaining engine oil life whenever the engine oil is changed. Otherwise, the
indication of remaining Oil life in the Oil Life Management System may not be accurate.
To reset the Oil Change Reminder, select ‘RESET’ from the infotainment system screen. Then,
select ‘Yes’ when the message “Has the engine oil been changed? Press [Yes] to reset the oil life.”

-If there is no alert until the maximum maintenance interval, have the vehicle checked by an
authorized retailer of Genesis Branded product.
