Tire Pressure Monitoring System (TPMS)

Driving

Tire Pressure Monitoring System (TPMS)

Instead of directly measuring the pressure in each tire, the TPMS on this vehicle 
monitors and compares the rolling radius and rotational characteristics of each 
wheel and tire while you are driving to determine if one or more tires are 
significantly under-inflated. This will cause the low tire pressure/TPMS indicator to 
come on and a message to appear on the driver information interface.

You must start TPMS calibration every time you:
• Adjust the pressure in one or more tires.
• Rotate the tires.
• Replace one or more tires.

Before calibrating the TPMS:
• Set the cold tire pressure in all four tires.

Make sure:
• The vehicle is at a complete stop.
• The transmission is in

Tire Pressure Monitoring System (TPMS)

The system does not monitor the tires when driving 
at low speed.

Conditions such as low ambient temperature and 
altitude change directly affect tire pressure and can 
trigger the low tire pressure/TPMS indicator to come 
on.

Tire pressure checked and inflated in:

•

Warm weather can become under-inflated in 
colder weather.

•

Cold weather can become over-inflated in warmer 
weather.

The low tire pressure indicator will not come on as a 
result of over inflation.

The TPMS may not function properly if tire type and 
size are mixed. Make sure to use the same size and 
type of tire.

2 Checking and Maintaining Tires P. 602

The low tire pressure/TPMS indicator may come on 
with a delay or may not come on at all when:

•

You rapidly accelerate, decelerate, or turn the 
steering wheel.

•

You drive on snowy or slippery roads.

•

Snow chains are used.

The low tire pressure/TPMS indicator may come on 
under the following conditions:

•

There is a heavier and uneven load on the tires than 
the condition at calibration.

•

Snow chains are used.

TPMS Calibration

•

The calibration process requires approximately 30 
minutes of cumulative driving at speeds between 
30-60 mph (48-97 km/h).

•

During this period, if the power mode is set to ON 
and the vehicle is not moved within 45 seconds, 
you may notice the low tire pressure indicator 
comes on briefly. This is normal and indicates that 
the calibration process is not yet complete.

If the snow chains are installed, remove them before 
calibrating the TPMS.

If the low tire pressure/TPMS indicator comes on even 
when the properly inflated specified regular tires are 
installed, have your vehicle checked by a dealer.

We recommend that the tires be replaced with the 
same brand, model, and size as the originals. Ask a 
dealer for details.

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.

U.S. models

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.

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.

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.

High Voltage Battery

Driving

High Voltage Battery

The High Voltage battery gradually discharges even if the vehicle is not in use. As a 
result, if your vehicle is parked for an extended period of time, the battery charge 
level will become low. Extended periods of time at a low state of charge will shorten 
battery life. To maintain the battery state of charge, drive your vehicle for more than 
30 minutes at least once every three months.
Extreme high temperatures can affect the battery life. You can minimize the effects 
by parking the vehicle in the shade during the summer.

High Voltage Battery

Be careful not to let the High Voltage battery drain 
too much. If the battery level becomes close to zero, 
it will make it impossible to start the engine.

Reference Lines

The area around the reference line 1 (red) is very close 
to your vehicle. As always, make sure to visually 
confirm the safety of a lane change before changing 
lanes.

The distance between your vehicle and lines 1, 2 and 
3 on the screen vary depending on road conditions 
and vehicle loading. For example, the reference lines 
on the screen may seem to appear closer than the 
actual distances when the rear of your vehicle is more 
heavily loaded.

Consult a dealer if:

•

The passenger side door mirror, or area around it is 
severely impacted, resulting in changing the 
camera angle.

 is designed to reduce the severity of an 

unavoidable collision. It does not prevent a collision 
nor stop the vehicle automatically. It is still your 
responsibility to operate the brake pedal and steering 
wheel appropriately according to the driving 
conditions.

The CMBS

TM

 may not activate or may not detect a 

vehicle in front of your vehicle under certain 
conditions:

For directions on the proper handling of the radar 
sensor, refer to the following page.

2 Radar Sensor P. 539

When the CMBS

TM

 activates, it may automatically 

apply the brake. It will be canceled when your vehicle 
stops or a potential collision is not determined.

The radar sensor is 
at the lower part of 
the front bumper.

The camera is located 
behind the rearview 
mirror.

The system starts monitoring the roadway ahead when your vehicle speed is about 
3 mph (5 km/h) and there is a vehicle in front of you.

When to use

The CMBS

TM

 activates when:

●

The speed difference between your vehicle and a vehicle or pedestrian detected 
in front of you becomes about 3 mph (5 km/h) and over with a chance of a 
collision.

●

Your vehicle speed is about 62 mph (100 km/h) or less and the system determines 
there is a chance of a collision with:

- Vehicles detected in front of you that are stationary, oncoming, or traveling in your 
same direction.
- A pedestrian who is detected in front of you.

●

Your vehicle speed is above 62 mph (100 km/h), and the system determines there 
is a chance of a collision with a vehicle detected in front of you traveling in your 
same direction.
