Driving
Lane Keeping Assist System (LKAS)
*
Provides steering input to help keep the vehicle in the middle of a detected lane and
provides audible and visual alerts if the vehicle is detected drifting out of its lane.
1Lane 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. 93
Do not place an object on the top of the instrument
panel. It may reflect onto the windshield and prevent
the system from detecting lane lines properly.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly under the following
conditions:•Your tires are over or under inflated.•Your tires or wheels are of varied size or
construction.•Your vehicle’s suspension has been altered,
changing the height of the vehicle.•Your vehicle has heavy load in the trunk or on the
rear seats.•A compact spare tire
* is mounted.
•Driving on snowy or wet roads.•Roadway lane markers are difficult to see due to
weather (rain, snow, fog, etc.) or road conditions.•Driving on a road with temporary lane markings.•Multiple or varied lane markings are visible on the
pavement due to road repairs or old lane markings.•Roadway objects or structures are misinterpreted
as lane markers.•On non-freeway roadways and on freeways with
many curves.
■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.
■Audible and visual alerts
Beeps and a warning display alert
you that the vehicle is drifting out of
a detected lane.
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.

uuWhen Driving uVehicle Stability Assist (VSA® ), aka Electronic Stability Control (ESC), System
Driving
Vehicle Stability Assist (VSA®), aka Electronic Stability Control (ESC), SystemVSA ® 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 ai r 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 cor ner 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.

This button is on the driver’s side control
panel. To turn the VSA® system on and off,
press and hold it until you hear a beep.
VSA ® will stop and the indicator will come on.
To turn it on again, press the (VSA ® OFF)
button until you hear a beep.
VSA ® is turned on every time you start the
engine, even if you turned it off the last time
you drove the vehicle.
■
VSA ® On and Off
1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control (ESC), System
Without VSA ®, your vehicle will have normal braking
and cornering ability, but it will not have VSA ®
traction and stability enhancement.
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 VSA ® system is off, the traction control
system is also off. 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 ® and traction control
systems switched off.
If the low tire pressure/TPMS indicator comes on or
blinks, the VSA ® system comes on automatically. In
this case, you cannot turn the system off by pressing
the button.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediatel y after starting the engine or
while driving. This is normal.

Driving
Tire Pressure Monitoring System (TPMS)
Monitors the tire pressure while you are
driving. If your vehicle’s tire pressure becomes
significantly low, the low tire pressure/TPMS
indicator comes on and a message appears on
the multi-information display.
1Tire Pressure Monitoring System (TPMS)
Conditions such as low ambient temperature and
altitude change di rectly affect tire pressure and can
trigger the low tire pr essure/TPMS indicator to come
on. 2 If the Low Tire Pressure/TPMS Indicator
Comes On or Blinks P. 486
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/TPMS indicator will not come
on as a result of over inflation.

Continued
Driving
Tire Pressure Monitoring System (TPMS) - Required Federal ExplanationEach tire, including th e 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. Un der-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.

384
uuWhen Driving uTire 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 il luminated. 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.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)Helps prevent the wheels from locking up, and help s you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pedal. This is sometimes referred to as
“stomp and steer.”■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Keep holding the
pedal firmly down. On dry pavement, you will need to press on the brake pedal very
hard before the ABS activates. However, you may feel the ABS activate immediately
if you are trying to stop on snow or ice.
When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.■
ABS
1 Anti-lock Brake System (ABS)NOTICEThe ABS may not function correctly if you use an
incorrect tire type and size.
When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have the vehicle
checked by a dealer immediately.
The ABS does not reduce the time or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, your vehicle may need more
stopping distance than a vehicle without the ABS:•When driving on rough road surfaces, including
when driving on uneven surfaces, such as gravel or
snow.•When tire chains are installed.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediatel y after starting the engine or
while driving. This is normal.
