Driving

Increase or decrease the vehicle speed using the RES/+ or –/SET buttons on the 
steering wheel.

• Each time you press the button, the vehicle speed is increased or decreased by 

about 1 mph or 1 km/h accordingly.

• If you keep the button pressed, the vehicle speed increases or decreases by about 

5 mph or 5 km/h accordingly.

To Adjust the Vehicle Speed

To Adjust the Vehicle Speed

If a vehicle detected ahead is going at a speed slower 
than your increased set speed, ACC may not 
accelerate your vehicle. This is to maintain the set 
following interval between your vehicle and the 
vehicle ahead.

You can set the vehicle speed using the –/SET button 
on the steering wheel when adjusting the speed with 
the accelerator and brake pedals.

• When the radar sensor inside the front grille gets dirty.
• The vehicle ahead of you cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA®, or CMBS

TM

Driving

Lane Keeping Assist System (LKAS)

Important Safety Reminders
The LKAS is for your convenience only. It is not a 
substitute for your vehicle control. The system does 
not work if you take your hands off the steering 
wheel or fail to steer the vehicle.

2 Multi-Information Display Warning and 

Information Messages P. 101

Do not place objects on the instrument panel. 
Objects may reflect on the front windshield and 
prevent correct detection of the traffic lanes.

LKAS only alerts you when lane drift is detected 
without a turn signal in use. LKAS may not detect all 
lane markings or lane departures; accuracy will vary 
based on weather, speed, and lane marker condition. 
It is always your responsibility to safely operate the 
vehicle and avoid collisions.

The LKAS is convenient when it is used on freeways.

The LKAS may not work properly or may work 
improperly under the certain conditions:

2 LKAS Conditions and Limitations P. 476

LKAS may not function as designed on while driving 
in frequent stop and go traffic, or on roads with 
sharp curves.

You can read about handling information for the 
camera equipped with this system.

 P. 450

When you operate the turn signals to change lanes, the system is suspended, and 
resumes after the signals are off.
If you make a lane change without operating the turn signals, the LKAS alerts 
activate, and torque is applied to the steering.

■

Steering input assist

The system applies torque to the steering to keep the vehicle between the left and 
right lane lines. The applied torque becomes stronger as the vehicle gets closer to 
either of the lane lines.

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

Driving

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

VSA® 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 output and selectively applying the brakes.

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

■

VSA® Operation

1

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

The 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® 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.

VSA® On and Off

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 VSA® temporarily switched off.

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 VSA® off if 
you are not able to free it when the VSA® is on.

Immediately after freeing your vehicle, be sure to 
switch VSA® on again. We do not recommend driving 
your vehicle with the VSA® system switched off.

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