Driving
Deceleration Paddle Selector
When you release the accelerator pedal, you can control the rate of deceleration 
without releasing your hands from the steering wheel. Using the deceleration 
paddle selector situated on the steering  wheel, you can sequentially shift through 
four stages of deceleration.
When descending a hill, you can use the deceleration paddle selector to help 
maintain the rate of deceleration, thereby allowing you to keep a safe distance 
between your vehicle and the vehicle ahead  as well as utilize regenerative braking.
The default deceleration stage is  . Each 
paddle selector oper ation makes a single 
stage deceleration change. u The deceleration stage may not change if 
you keep the paddle selector pulled 
back.
To select the different stages of deceleration:
• Pull back the 
(+ selector (right side) to decrease the deceleration stage.
• Pull back the 
(- selector (left side) to increase the deceleration stage.
Pull the 
(+ selector for a few seconds when yo u want to cancel the deceleration 
paddle selector.
1 Deceleration Paddle Selector
If you are descending a hill when you select stage  , 
the vehicle may enter stage  .
If you pull back right and le ft paddle selector at the 
same time, the deceleration stage may not change.
3CAUTION
Rapidly increasing the deceleration rate by 
quickly shifting the deceleration paddle 
can cause the tires to skid, resulting in a 
crash that could injure or kill someone.
Always maintain a re asonable rate of 
deceleration.

Driving
Road Departure Mitigation (RDM) System
Alerts and helps to assist you when the system detects a possibility of your vehicle 
unintentionally crossing over detected lane markings and/or leaving the roadway 
altogether.
The front camera behind the rearview mirror 
monitors left and right lane markings (in white 
or yellow). If your vehicl e is getting too close to 
detected lane markings  without a turn signal 
activated, the system, in addition to a visual 
alert, applies steering torque and alerts you 
with rapid vibrations on  the steering wheel, to 
help you remain within the detected lane.
2 Customized Features P. 280
As a visual alert, the  Lane Departure 
message appears on the driver information 
interface.
If the system determines that its steering input 
is insufficient to keep your vehicle on the 
roadway, it may apply braking.
u Braking is applied only when the lane 
markings are solid continuous lines.
The system cancels assisting operations wh en you turn the steering wheel to avoid 
crossing over detected lane markings.
If the system operates several times with out detecting driver response, the system 
beeps to alert you.
■How the System Works
1 Road Departure Mitigation (RDM) System
Important Safety Reminder
Like all assistance systems, the RDM system has 
limitations.
Over-reliance on the RDM system may result in a 
collision. It is always your  responsibility to keep the 
vehicle within your driving lane.
The RDM system only alerts  you when lane drift is 
detected without a turn signal in use. The RDM 
system may not detect all la ne markings or lane or 
roadway departures; accu racy will vary based on 
weather, speed and lane marker condition. It is 
always your responsibilit y to safely operate the 
vehicle and avoid collisions.
You can read about handling information for the 
camera equipped with this system.

The system becomes ready to start sear ching for lane markings when all the 
following conditions are met:
• The vehicle is traveling between about 45 and 90 mph (72 and 145 km/h).
• The vehicle is on a straight  or slightly curved road.
• The turn signals are off.
• The brake pedal is not depressed.
• The wipers are not in continuous operation.
• The vehicle is not accelerating or braking, and the steering wheel is not being 
turned.
• The system makes a determination that the driver is not actively accelerating, 
braking or steering.
Press the RDM button to turn the system on 
and off.u The indicator in the button comes on and 
the message appears on the driver

Increase or decrease the vehicle speed using the  RES/+ or −/SET  button on the 
steering wheel.
• Each time you press the  RES/+ or −/SET  button, the vehicle speed is increased or 
decreased by about 1 mph or 1 km/h accordingly.
• If you press and hold the  RES/+ or −/SET button, the vehicle speed increases or 
decreases by about 5 mph  or 5 km/h accordingly.
■To Adjust the Vehicle Speed1To Adjust the Vehicle Speed
If a vehicle detected ahead is going at a speed slower 
than your increased set speed, ACC with LSF may not 
accelerate your vehicle. This is to maintain the set 
interval between your vehi cle and the vehicle ahead.

■Automatic ca ncellation
The beeper sounds and a message appears on the driver information interface when 
ACC with LSF is automatically canceled.  Any of these conditions may cause the ACC 
with LSF to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the front grille gets dirty.
• An abnormal tire condition is de tected, 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 is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the AC C with LSF range is too close to your 
vehicle.
• The camera behind the rearview mirror,  or the area around the camera, including 
the windshield, gets dirty.
The ACC with LSF automatic cancellation ca n be also triggered by the following 
causes. In these cases, the parking  brake will be automatically applied.
• The driver’s seat belt is unfastened when the vehicle is stationary.
• The vehicle stops for more than 10 minutes.
• The power system is turned off.
1Automatic cancellation
Even though ACC with LSF has been automatically 
canceled, you can still resu me the prior set speed. 
Wait until the condition that caused ACC with LSF to 
cancel improves, then press the  RES/+ button.
