than what was intended. It also assists in maintaining traction on slippery surfaces. 
It does so by regulating engine and motor output and selectively applying the

Blind spot information System

Continued

Driving

Blind spot information System

Is designed to detect vehicles in specified alert zones adjacent to your vehicle, 
particularly in harder to see areas commonly known as “blind spots.” When the 
system detects vehicles approaching from behind in adjacent lanes, the appropriate 
indicator comes on for a few seconds, providing assistance when you change lanes.

■

How the system works

1

Blind spot information System

Important Safety Reminder

Like all assistance systems, blind spot information 
system has limitations. Over reliance on the blind spot 
information system may result in a collision.

The system is for your convenience only. Even if an 
object is within the alert zone, the following 
situations may occur.

•

The blind spot information system alert indicator 
may not come on due to obstruction (splashes, 
etc.) even without the 

Blind Spot Info Not 

Available

 multi-information display appearing.

•

The blind spot information system alert indicator 
may come on even with the message appearing.

The blind spot information system alert indicator may 
not come on under the following conditions:

•

A vehicle does not stay in the alert zone for more 
than two seconds.

•

A vehicle is parked in a side lane.

•

The speed difference between your vehicle and the 
vehicle you are passing is greater than 6 mph (10 km/h).

WARNING

Failure to visually confirm that it is safe to 
change lanes before doing so may result in 
a crash and serious injury or death. 
Do not rely only on the blind spot 
information system when changing lanes.

Always look in your mirrors, to either side 
of your vehicle, and behind you for other 
vehicles before changing lanes.

Blind spot information system may be adversely 
affected when:

•

Objects (guard rails, poles, trees, etc.) are detected.

•

An object that does not reflect radio waves well, 
such as a motorcycle, is in the alert zone.

•

Driving on a curved road.

•

A vehicle is moving from a far lane to the adjacent 
lane.

•

The system picks up external electrical interference.

•

The rear bumper or the sensors have been improperly 
repaired or the rear bumper has been deformed.

•

The orientation of the sensors has been changed.

•

In bad weather (Heavy rain, snow, and fog).

For proper blind spot information system operation:

•

Always keep the rear bumper corner area clean.

•

Do not cover the rear bumper corner area with 
labels or stickers of any kind.

•

Take your vehicle to a dealer if you need the rear 
bumper corner area or the radar sensors to be repaired, 
or the rear bumper corner area is strongly impacted.

Tire Pressure Monitoring System (TPMS)

indicator comes on and a message appears on 
the multi-information display.

Tire Pressure Monitoring System (TPMS) - Required Federal Explanation

Continued

Driving

Tire Pressure Monitoring System (TPMS) - Required 
Federal Explanation

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.

448

uu

When Driving

u

Tire Pressure Monitoring System (TPMS) - Required Federal Explanation

Driving

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.

High Voltage Battery

Driving

High Voltage Battery

The High Voltage battery gradually discharges when the vehicle is not in use. As a 
result, if your vehicle is parked for an extended period of time, the battery level may 
get low. Keeping your vehicle’s battery level low can shorten the battery life. To 
maintain the battery, drive your vehicle for more than 30 minutes to recharge the 
battery at least once every three months.
To help maintain the battery life, when parking under the direct sunlight during 
summer, try find a shaded area.
