Driving
■Automatic cancellation
The beeper sounds and a message appears on the driver information interface when
ACC with Low Speed Follow is automatically canceled. Any of these conditions may
cause the ACC with Low Speed Fo llow to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the lower bumper next to the fog light
* gets dirty.
• The vehicle ahead of yo u cannot be detected.
• 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 Low Speed Follow range is too
close to your vehicle.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
• When the Maximum Load Limit is exceeded.
• When passing through an enclosed space, such as tunnel.
The ACC with Low Speed Follow automatic cancellation can 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 engine is turned off.
1Automatic cancellation
Even though ACC with Low Speed Follow has been
automatically canceled, you can still resume the prior

Driving
Adaptive Cruise Control (ACC)*
Helps maintain a constant vehicle speed a nd a set following-interval behind a vehicle
detected ahead of yours, without you havi ng to keep your foot on the brake or the
accelerator.1 Adaptive Cruise Control (ACC)*
Important Reminder
As with any system, there are limits to ACC. Use the
brake pedal whenever necessary, and always keep a
safe interval betw een your vehicle and other vehicles.
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 548
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 546
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when traveling on open
highways in good weather.
3WARNING
ACC has limited braking capability.
When your vehicle speed drops below 22
mph (35 km/h), ACC will automatically
cancel and no longer will apply your
vehicle’s brakes.
Always be prepared to apply the brake
pedal when conditions require.
When to use
■Vehicle speed for adaptive cruise control: Desired speed in a range above
roughly 25 mph (40 km/h) ~ The radar sensor is in
the lower bumper
next to the fog light.
Be careful not to have
the radar sensor cover
strongly impacted.
The camera is
located behind
the rearview
mirror.

■How to activate the system1Adaptive Cruise Control (ACC)*
The radar sensor for ACC is shared with the collision
mitigation braking systemTM (CMBSTM).
2 Collision Mitigation Braking SystemTM
(CMBSTM) P. 491
ACC may not work properly under certain conditions.
2 ACC Conditions and Limitations P. 523
When the engine speed slows down, try to
downshift. You can maintain the set speed if you
change gear within five seconds.
When not using ACC: Turn off adaptive cruise by
pressing the MAIN button. This also will turn off the
Lane Keeping Assist System (LKAS).
When the MAIN button is pressed, both ACC and
the Lane Keeping Assist System (LKAS) are either
turned on or off.
Do not use ACC under the following conditions:
•On roads with heavy traf fic or while driving in
continuous stop and go traffic.
•On roads with sharp turns.
•On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, ACC will not apply the brakes to maintain
the set speed.
•On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.
How to use
■Press the MAIN button on
the steering wheel.
ACC (green) is on in the instrument panel.
ACC is ready to use.

Handling the Unexpected
If a Tire Goes Flat
Temporarily Repairing a Flat Tire
If the tire has a large cut or is otherwise severely damaged, you will need to have the
vehicle towed. If the tire only has a small puncture, from a nail for instance, you can
use the temporary tire repair kit so that you can drive to the nearest service station
for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1. Park the vehicle on a firm, level, and n on-slippery surface, and apply the parking
brake.
2. Put the transmission into
(R.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF
(LOCK).
Models with temporary tire repair kit
1 Temporarily Repairing a Flat Tire
The kit should not be used in the following situations.
Instead, contact a dealer or roadside assistance to
have the vehicle towed.
•The tire sealant has expired.•More than one tire is punctured.•The puncture or cut is larger than 3/16 inch (4 mm).•The tire side wall is da maged or the puncture is
outside the contact area.
•Damage has been caused by driving with the tire
extremely under inflated.
•The tire bead is no longer seated.•The rim is damaged.
Do not remove a nail or screw that punctured the
tire. If you remove it from the tire, you may not be
able to repair the puncture using the kit.
NOTICE
Do not use a puncture-repairing agent other than the
one provided in the kit that came with your vehicle. If
a different agent is used, you may permanently
damage the tire pressure sensor.
When the puncture is:Use Kit
