Vehicle Stability Assist (VSA®), aka Electronic Stability Control (ESC), System

Driving

Vehicle Stability Assist (VSA®), aka Electronic 
Stability Control (ESC), System

Helps to stabilize the vehicle during cornering if the vehicle turns more or less 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 brakes.

When VSA® activates, you may notice that the 
engine and motor do not respond to the 
accelerator. You may also notice some noise 
from the hydraulic system. You will also see 
the indicator blink.

■

VSA® Operation

Vehicle Stability Assist (VSA®), aka Electronic Stability Control 
(ESC), System

VSA® may not function properly if tire type and size 
are mixed. Make sure to use the same size and type 
of tire, and the air pressures as specified.

When the VSA® system indicator comes on and stays 
on while driving, there may be a problem with the 
system. While this may not interfere with normal 
driving, have your vehicle checked by a dealer 
immediately.

VSA® cannot enhance stability in all driving situations 
and does not control the entire braking system. You 
still need to drive and corner at speeds appropriate 
for the conditions and always leave a sufficient 
margin of safety.

The main function of the VSA® system is generally 
known as Electronic Stability Control (ESC). The 
system also includes a traction control function.

Vehicle Stability Assist (VSA®), aka Electronic Stability Control 
(ESC), System

With the 

 button pressed, your vehicle will have 

normal braking and cornering ability, but VSA® 
traction and stability enhancement becomes less 
effective.

In certain unusual conditions when your vehicle gets 
stuck in shallow mud or fresh snow, it may be easier 
to free it with the 

 button pressed.

When the 

 button is pressed, the traction control 

function becomes less effective. This allows for the 
wheels to spin more freely at low speed. You should 
only attempt to free your vehicle with the 

 button 

pressed if you are not able to free it without.

Immediately after freeing your vehicle, be sure to 
press the 

 button again. We do not recommend 

driving your vehicle with the 

 button pressed 

(indicator on).

You may hear a motor sound coming from the 
engine compartment while system checks are being 
performed immediately after turning the power 
system on or while driving. This is normal.

The system controls and transfers varying amounts of motor and/or engine torque 
to each wheel in accordance with the driving conditions.

SPORT HYBRID SH-AWD® helps to enhance driving stability, and lets you handle 
situations like slippery surfaces, such as snow, sand, mud, and steep hills, better 
than when driving with standard two wheel drive. However, the system does not 
help to enhance braking. Be cautious about the following:
• It is still your responsibility to drive safely when you steer, accelerate, and apply 

brakes.

• Leave a sufficient margin when braking on slippery surfaces.

Blind Spot Information (BSI) System

Driving

Blind Spot Information (BSI) 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 (BSI) System

Important Safety Reminder
Like all assistance systems, BSI has limitations. Over 
reliance on BSI 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 BSI alert indicator may not come on due to 
obstruction (splashes, etc.) even without the Blind 
Spot Not Available multi-information display 
appearing.

•

The BSI alert indicator may come on even with the 
message appearing.

The BSI 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).

3

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.

Alert zone range
A: Approx. 1.6 ft. (0.5 m)
B: Approx. 10 ft. (3 m)
C: Approx. 10 ft. (3 m)

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.

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.

Foot Brake

Foot Brake

Check the brakes after driving through deep water, 
or if there is a buildup of road surface water. If 
necessary, dry the brakes by lightly depressing the 
pedal several times.

If you hear a continuous metallic friction sound when 
applying the brakes, this is caused by the brake wear 
indicator rubbing on the brake rotor and indicates 
that the brake pads need to be replaced. Have the 
vehicle checked by a dealer. If you hear only an 
occasional squeak or squeal when you initially apply 
the brake pedal, this may be normal and caused by 
high frequency vibration of the brake pads against 
the rotating brake disc.

Constantly using the brake pedal while going down a 
long hill builds up heat, which reduces the brake 
effectiveness. Apply regenerative braking by taking 
your foot off the accelerator pedal and downshifting 
to a lower gear.

Do not rest your foot on the brake pedal while 
driving, as it will lightly apply the brakes and cause 
them to lose effectiveness over time and reduce pad 
life. It will also confuse drivers behind you.
