Shift Lever Operation
1Shift Lever OperationNOTICEWhen you change the shift lever from
(D to
(R and
vice versa, come to a complete stop and keep the
brake pedal depressed.
Operating the shift lever before the vehicle has come
to a complete standstill can damage the transmission.
Use the shift lever position indicator to check the
lever position before pulling away.
If the transmission indicator blinks when driving, in
any shift position, there is a problem with the
transmission.
Avoid sudden acceleration and have the transmission
checked by a dealer as soon as possible.
The fuel supply may be cut off if you drive at engine
speeds in or over the tachometer’s red zone (engine
speed limit). If this happens, you may experience a
slight jolt.
When the engine speed is increased while the shift
lever is in
( N, (P or
(R, the fuel supply may be cut
off even without the engine speed entering the
tachometer’s red zone.
It may not be possible to operate the shift lever if the
brake pedal is applied while the shift lever release
button is held down.
Depress the brake pedal first.

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.

uuBraking uBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist
helps reduce the effort needed on the brake pedal. The brake assist system increases
the stopping force when you depress the brake pedal hard in an emergency
situation. The anti-lock brake system (ABS) helps you retain steering control when
braking very hard.2 Brake Assist System P. 391
2 Anti-lock Brake System (ABS) P. 390■
Foot Brake
1Foot 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, the brake pads need to be
replaced. Have the vehicle checked by a dealer.
Constantly using the brake pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply engine 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.
Your vehicle is equipped with a hydraulic brake
booster that, under certain conditions, such as
braking at high altitudes, supplements the vacuum
power assist. When the hydraulic brake booster
activates, you may hear a motor sound and a slight
vibration in the pedal. This is normal.

uuBraking uBrake System
Driving
■The system automatically cancels when:
• You depress the brake pedal and move the shift lever to
(P
or
(R
.
• You engage the parking brake.
Under the following conditions, the system automatically cancels, and the parking
brake is applied:
• Braking is kept for more than 10 minutes.
• The driver’s seat belt is unfastened.
• The engine is turned off.
• Brake Hold System Problem /CHECK BRAKE HOLD SYSTEM appears on the
multi-information display.
■Turning off the automatic brake hold system While the system is on, press the automatic
brake hold button again.u The automatic brake hold system
indicator goes off.
If you want to turn off automatic brake hold
while the system is in operation, press the
automatic brake hold button with the brake
pedal depressed.
1 Automatic Brake Hold
While the system is activa ted, you can turn off the
engine or park the vehicle through the same
procedure as you normally do. 2 When Stopped P. 398
Whether the system is on, or the system is activated,
the automatic brake hold turns off once the engine is
off.1 Turning on the system
Make sure to turn off the automatic brake hold
system before using an automated car wash.
You may hear an operating noise if the vehicle moves
while the automatic brake hold system is in
operation. The system generates sound while holding
the vehicle and it moves.

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.
