The speedometer reading can be
displayed in either English or metric
units. SeeDriver Information Center
(DIC) 0109. The increment value
used depends on the units
displayed.
Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated:
. Move the thumbwheel toward
SET/− and hold until the desired
lower speed is reached, then
release it.
. To decrease the vehicle speed in
smaller increments, move the
thumbwheel toward SET/−
briefly. For each press, the
vehicle goes about 1 km/h
(1 mph) slower.
The speedometer reading can be
displayed in either English or metric
units. See Driver Information Center
(DIC) 0109. The increment value
used depends on the units
displayed. Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle slows down to the previous
set cruise control speed. While
pressing the accelerator pedal or
shortly following the release to
override cruise control, briefly
moving the thumbwheel toward
SET/- will result in cruise control set
to the current vehicle speed.
Using Cruise Control on Hills
How well cruise control works on
hills depends on the vehicle speed,
load, and the steepness of the hills.
When going up steep hills, you
might have to step on the
accelerator pedal to maintain the
vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to keep your
speed down. If the brake pedal is
applied, cruise control will
disengage.
Ending Cruise Control
There are four ways to end cruise
control:
.
To disengage cruise control,
step lightly on the brake pedal.
. Press
n.
. Shift the transmission to
N (Neutral).
. To turn off cruise control,
press
o.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
ois
pressed or if the ignition is
turned off.

194 Driving and Operating
.The Park Assist sensors are
covered by frost or ice. Frost or
ice can form around and behind
the sensors and may not always
be seen; this can occur after
washing the vehicle in cold
weather. The message may not
clear until the frost or ice has
melted.
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system.
PARK ASSIST OFF : If the RPA
system does not activate due to a
temporary condition, the message
displays on the DIC. This can occur
under the following conditions:
. An object was hanging out of the
trunk during the last drive cycle.
Once the object is removed,
RPA will return to normal
operation.
. The bumper is damaged. Take
the vehicle to your dealer to
repair the system. .
Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.
Forward Collision Alert
(FCA) System
If equipped, the FCA system may
help to avoid or reduce the harm
caused by front-end crashes. When
approaching a vehicle ahead too
quickly, FCA provides a red flashing
alert on the windshield and rapidly
beeps.
FCA detects vehicles within a
distance of approximately 60 m
(197 ft) and operates at speeds
above 40 km/h (25 mph).
{Warning
FCA is a warning system and
does not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
(Continued)
Warning (Continued)
closely, FCA may not provide a
warning with enough time to help
avoid a crash. It also may not
provide any warning at all. FCA
does not warn of pedestrians,
animals, signs, guardrails,
bridges, construction barrels,
or other objects. Be ready to take
action and apply the brakes. See
Defensive Driving0160.
FCA can be disabled with the FCA
steering wheel control.
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. When a vehicle is detected,
the vehicle ahead indicator will

display green. Vehicles may not be
detected on curves, highway exit
ramps, or hills, due to poor visibility;
or if a vehicle ahead is partially
blocked by pedestrians or other
objects. FCA will not detect another
vehicle ahead until it is completely
in the driving lane.
{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.Collision Alert
When your vehicle approaches
another detected vehicle too rapidly,
the red FCA display on top of the
instrument panel to the right of the
steering wheel will flash. Also,
several rapid high-pitched beeps will
sound from the front. When this
Collision Alert occurs, the brake
system may prepare for driver
braking to occur more rapidly which
can cause a brief, mild deceleration.
Continue to apply the brake pedal
as needed. Cruise control may be
disengaged when the Collision Alert
occurs.
Tailgating Alert
The red FCA display will stay
continuously illuminated when you
are following a detected vehicle
ahead much too closely.
Selecting the Alert Timing
The Collision Alert control is on the
steering wheel. Press COLLISION
ALERT to set the alert timing to far,
medium, near, or off. The first button
press shows the current control
setting on the DIC. Additional button
presses will change this setting. The
chosen setting will remain until it is
changed and will affect both the
Collision Alert and the Tailgating
Alert features. The timing of both
alerts will vary based on vehicle
speed. The faster the vehicle speed,
the farther away the alert will occur.
Consider traffic and weather
conditions when selecting the alert
timing. The range of selectable alert
timing may not be appropriate for all
drivers and driving conditions.
Unnecessary Alerts
FCA may sometimes set
unnecessary alerts to turning
vehicles, vehicles in other lanes,
objects that are not vehicles,
or shadows. These alerts are
normal operation and the vehicle
does not need service.

Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil. Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0210.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
If the engine oil pressure light
comes on, check the engine oil level
right away. The oil pressure light is
on the instrument cluster. See
Engine Oil Pressure Light 0106.
Check the engine oil level regularly;
this is an added reminder.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0 207 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center
(DIC) message displays, check the
oil level.

218 Vehicle Care
Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. SeeEngine
Compartment Overview 0207 for
reservoir location.
Caution
. Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.
. Do not use engine coolant
(antifreeze) in the
windshield washer. It can
damage the windshield
washer system and paint.
(Continued)
Caution (Continued)
.Do not mix water with
ready-to-use washer fluid.
Water can cause the
solution to freeze and
damage the washer fluid
tank and other parts of the
washer system.
. When using concentrated
washer fluid, follow the
manufacturer instructions for
adding water.
. Fill the washer fluid tank
only three-quarters full when
it is very cold. This allows
for fluid expansion if
freezing occurs, which could
damage the tank if it is
completely full.
Brakes
Disc brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or can be heard all the time when the
vehicle is moving, except when
applying the brake pedal firmly.
{Warning
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
