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

on as a result of over inflation.

The TPMS audibly and visually informs you of 
changes in tire pressure of the individual tire that you 
are adjusting using audible and visual indications.

If a change in tire pressure has been significant, the 
system beeps and the hazard lights flash continuously

Tire Pressure Monitoring System (TPMS) - Required Federal Explanation

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.

409

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.

Blind spot information System

*

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.

Blind spot information System

*

Important Safety Reminder

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

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).

•

An object not detected by the radar sensors 
approaches or passes your vehicle.

•

A vehicle running in the adjacent lane is a 
motorcycle or other small vehicle.

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.
