Limitations of the System
The predictive shift may have limited
operation in the following situations

[If you do not take the route guided in
the navigation, predictive shift may
not operate properly since the system
operates according to the navigated
route. Predictive shift will operate
properly again once the navigation
sets a new route.

[The navigation may reflect the real
time traffic condition and change the
route. If so, the predictive shift may
not correspond temporarily to the
current driving condition.

[If the destination is not set on the
navigation, predictive shift operates
according to the route which is most
likely to be taken. When driving
through roads such as a branch road,
predictive shift may not correspond to
the current driving condition until the
navigation sets a new route.

[While using the navigation app
through smart phone linked functions
such as Android Auto or Apple
CarPlay, predictive shift operates as
when the destination is not set in the
vehicle’s navigation.

[Predictive shift may not operate
properly in the following situations.
-Navigation system is not completely
booted.
-Real time GPS or map data has
errors, or the map data is not up to
date.
Checking Operation on the
Instrument Cluster
The operating condition of predictive
shift can be checked from the icons and
messages displayed on the instrument
cluster. If there are multiple conditions
detected, every related icon illuminates
but only the most important message
is displayed. The images and colors
of the messages may differ from the
description depending on the cluster
type.
CAUTION
Always be aware of the traffic and
road condition ahead. Checking the
instrument cluster while driving
may cause an accident.

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

275/35R21 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.
