speed is within a suitable range.
If not suitable, SHIFT DENIED
will be displayed in the DIC, and
the transmission will not shift
gears. Continuing to hold the
lever in the −(Minus) position
will select the requested gear as
soon as the vehicle speed
decreases to the allowed speed
for that gear.
.If the engine speed becomes too
low for the currently selected
gear, the transmission will
automatically shift down, even
though A/S mode is still
selected.
.While in A/S mode, 2 (Second)
or 3 (Third) gear starts can be
selected from a standing start.
This is useful for gentle
acceleration on slippery
surfaces.

Caution (Continued)
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake lining life.
The EPB can also be used to
prevent roll back for vehicles with a
manual transmission taking off on a
hill. When no roll back is desired, an
applied EPB will allow both feet to
be used for the clutch and
accelerator pedals in preparation for
starting the vehicle moving in the
intended direction. In this case,
there is no need to push the switch
to release the EPB.
Brake Assist
The Brake Assist feature is
designed to assist the driver in
stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal as
the driving situation dictates. The
Brake Assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.
Hill Start Assist (HSA)
This vehicle has an HSA feature,
which may be useful when the
vehicle is stopped on a grade
sufficient enough to activate HSA.
This feature is designed to prevent
the vehicle from rolling, either
forward or rearward, during vehicle
drive off. After the driver completely
stops and holds the vehicle in a
complete standstill on a grade, HSA
will be automatically activated.
During the transition period between
when the driver releases the brake
pedal and starts to accelerate to
drive off on a grade, HSA holds the
braking pressure for a maximum of
two seconds to ensure that there is
no rolling. The brakes will
automatically release when the
accelerator pedal is applied within
the two-second window.

highway driving.
Sport: Use where road conditions or
personal preference demand more
control. This setting selects a
suspension calibration that provides
a firmer reaction to road conditions.
Performance/Track: This is the
firmest setting. This setting is for
smoother road surfaces and when a
more performance-oriented
suspension style is preferred.
It provides better high speed
stability, handling response, and
body control.

the clutch pedal, while maintaining
the fully pressed accelerator pedal,
will manage wheel slip. SeeManual
Transmission on page 9-27.
After the vehicle is launched, the
system continues in Track
Driver Mode.
Limited-Slip Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow,
mud, ice, sand, or gravel. When
traction is low, this feature allows
the drive wheel with the most
traction to move the vehicle. The
limited-slip rear axle also gives the
driver enhanced control when
cornering hard or completing a
maneuver, such as a lane change.
For vehicles with limited slip
differential, driven under severe
conditions, the rear axle fluid should
be changed. See Track Driver Mode
on page 9-36 andMaintenance
Schedule on page 11-2.
Cruise Control
With cruise control, the vehicle can
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If the vehicle has the StabiliTrak
®
system and begins to limit wheel
spin while using cruise control, the
cruise control will automatically disengage. See
Traction Control/
Electronic Stability Control on
page 9-32. If a collision alert occurs
when cruise control is activated,
cruise control is disengaged. See
Forward Collision Alert (FCA)
System on page 9-46. When road
conditions allow you to safely use it
again, the cruise control can be
turned back on.
If the brakes are applied, cruise
control disengages.

After completely passing a large
enough space bordered by two
vehicles or other objects, an audible
beep occurs and a red symbol
displays in the DIC.
APA will instruct the vehicle to stop
once a large enough space is found.
Follow the instructions in the DIC.
When instructed to drive in reverse,
shift to R (Reverse) to engage
automatic steering. The steering
wheel will vibrate briefly as a
reminder to remove hands from the
steering wheel. Check surroundings
and continue braking or accelerating
as needed, and be prepared to stop
to avoid vehicles, pedestrians,
or objects. If the vehicle is inR (Reverse), but does not steer into
the expected space, this may be
because the system is maneuvering
the vehicle into a previously
detected space. The APA system
does not need service.
A DIC progress arrow displays the
status of the parking maneuver.
Depending on the space size,
additional maneuvers may be
required, and there will be additional
instructions. When changing gears,
allow the automatic steering to
complete before continuing the
parking maneuver. Upon completion
of a successful maneuver, APA will
beep and display a PARKING
COMPLETE message. Place the
vehicle in P (Park) for an automatic
transmission or in N (Neutral) with
the parking brake set for a manual
transmission.
APA may automatically disengage if:
.The steering wheel is used by
the driver.
.If the vehicle exceeds
10 km/h (6 mph).
.There is a failure with the APA
system.
.Electronic stability control or
antilock brakes are activated.
.An important vehicle message is
displayed in the DIC.
.An incoming call is received
through a connected phone.
Disconnect the phone from the
vehicle to prevent APA from
disengaging.
APA search is only available when
the vehicle speed is below 30 km/h
(18 mph).
The APA system is constantly
scanning for parking spaces when
the vehicle is moving forward.
A suitable space will be offered
even when the APA button is
pressed after the initial drive-by.
The APA system is capable of
parking in subsequent spots after
the first parking space is found.
To cancel APA, press the APA
button again.

Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Display the REMAINING OILLIFE on the DIC. See Driver
Information Center (DIC) on
page 5-20.
2. Press and hold the SET/CLR button on the DIC while the Oil
Life display is active. The oil life
will change to 100%.
The oil life system can also be reset
as follows:
1. Turn the ignition to ON/RUN with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
The system is reset when the
CHANGE ENGINE OIL SOON
message goes off. If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.

How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer service department and have
it repaired as soon as possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, you should
have this done at your dealer
service department. Contact your
dealer for additional information or
the procedure can be found in the
ProCarManuals.com
