Parking Assist (UFRPA) system, this display allows the
system to be turned on or off. Once in this display, press
the set/reset button to select between ON or OFF. If you
choose ON, the system will be turned on. If you choose
OFF, the system will be turned off. The UFRPA system
automatically turns back on after each vehicle start.
When the UFRPA system is turned off and the vehicle is
shifted out of P (Park), the DIC will display the PARKING
ASSIST OFF message as a reminder that the system
has been turned off. SeeDIC Warnings and Messages
on page 3-73andUltrasonic Front and Rear Parking
Assist (UFRPA) on page 2-42for more information.
SIDE BLIND ZONE ALERT
If your vehicle has the Side Blind Zone Alert (SBZA)
system, this display allows the system to be turned on
or off. Once in this display, press the set/reset button to
select between ON or OFF. If you choose ON, the system
will be turned on. If you choose OFF, the system will beturned off. When the SBZA system is turned off, the DIC
will display the SIDE BLIND ZONE ALERT SYSTEM OFF
message as a reminder that the system has been turned
off. SeeDIC Warnings and Messages on page 3-73and
Side Blind Zone Alert (SBZA) on page 2-45for more
information.
FRONT TIRES or REAR TIRES
On vehicles with the Tire Pressure Monitor
System (TPMS), the pressure for each tire can be
viewed in the DIC. The tire pressure will be shown in
either pounds per square inch (psi) or kilopascals (kPa).
Press the vehicle information button until the DIC
displays FRONT TIRES PSI (kPa) LEFT ## RIGHT ##.
Press the vehicle information button again until the
DIC displays REAR TIRES PSI (kPa) LEFT ##
RIGHT ##.
If a low or high tire pressure condition is detected by
the system while driving, a message advising you
to check the pressure in a specic tire will appear in
the display. SeeInflation - Tire Pressure on page 5-57
andDIC Warnings and Messages on page 3-73for
more information.
If the tire pressure display shows dashes instead of
a value, there may be a problem with your vehicle. If this
consistently occurs, see your dealer/retailer for service.

CHECK TIRE PRESSURE
On vehicles with the Tire Pressure Monitor System
(TPMS), this message displays when the pressure in
one or more of the vehicle’s tires needs to be checked.
This message also displays LEFT FRONT, RIGHT
FRONT, LEFT REAR, or RIGHT REAR to indicate which
tire needs to be checked. You can receive more than
one tire pressure message at a time. To read the other
messages that may have been sent at the same time,
press the set/reset button. If a tire pressure message
appears on the DIC, stop as soon as you can. Have the
tire pressures checked and set to those shown on the
Tire Loading Information label. SeeTires on page 5-48,
Loading the Vehicle on page 4-19, andInflation - Tire
Pressure on page 5-57. The DIC also shows the tire
pressure values. SeeDIC Operation and Displays on
page 3-68. If the tire pressure is low, the low tire pressure
warning light comes on. SeeTire Pressure Light on
page 3-60.
CLEAN RADAR
This message displays when the Adaptive
Cruise Control (ACC) system and the Forward
Collision Alert (FCA) system are disabled because
the radar is blocked and cannot detect vehicles in
your path. It may also activate during heavy rain or
due to road spray. To clean the system, see “Cleaning
the System” underAdaptive Cruise Control on page 3-19.
CRUISE SET TO XXX MPH (km/h)
This message displays whenever the cruise control is
set. SeeCruise Control on page 3-16andAdaptive
Cruise Control on page 3-19for more information.
If your vehicle has Adaptive Cruise Control (ACC), after
a few seconds, this message clears and the message
“SET SPD XX” displays at the bottom of the DIC.
See “SET SPD (Speed)” later in this section.
DRIVER DOOR OPEN
This symbol appears with
this message.
This message displays when the driver door is not
closed completely. Make sure that the door is closed
completely.

A ve-tire rotation pattern may be used for your
professional vehicle, if it has a full-size spare tire
and wheel assembly that matches the original
equipment tires and wheels in size, type and brand.
The correct ve-tire rotation pattern is shown.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the
Tire and Loading Information label. SeeLoading
the Vehicle on page 4-19.Vehicles that have the Tire Pressure Monitor
System (TPMS) will need to have the sensors
reset after a tire rotation is performed. See
Tire Pressure Monitor System on page 5-60.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-103.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the
vehicle. In an emergency, you can use a
cloth or a paper towel to do this; but be sure
to use a scraper or wire brush later, if
needed, to get all the rust or dirt off. See
Changing a Flat Tire on page 5-74.Five-Tire Rotation Pattern

Scheduled Maintenance
To maintain the ride, handling, and performance of
the vehicle, it is important that the rst tire rotation
service be performed when the vehicle has 5,000 to
8,000 miles (8 000 to 13 000 km). Check tires for
ination pressures and wear. SeeTires on page 5-48.
Rotate tires. SeeTire Inspection and Rotation on
page 5-65and “Tire Wear Inspection” inAt Least Once
a Month on page 6-9.
When the CHANGE ENGINE OIL SOON message
displays in the Driver Information Center (DIC), service
is required for the vehicle. Have the vehicle serviced
as soon as possible within the next 600 miles
(1 000 km). It is possible that, if driving under the best
conditions, the engine oil life system may not indicate
that vehicle service is necessary for over a year.
However, the engine oil and lter must be changed at
least once a year and at this time the system must
be reset. Your dealer/retailer has trained service
technicians who will perform this work using genuine
parts and reset the system.
If the engine oil life system is ever reset accidentally,
service the vehicle within 3,000 miles (5 000 km)
since the last service. Remember to reset the oil life
system whenever the oil is changed. SeeEngine Oil Life
System on page 5-16for information on the Engine
Oil Life System and resetting the system.When the CHANGE ENGINE OIL SOON message
appears, the following services, checks, and inspections
are required:
❑Change engine oil and lter. SeeEngine Oil on
page 5-13. Reset oil life system. SeeEngine Oil Life
System on page 5-16.An Emission Control Service.
❑Visually check for any leaks or damage.
See footnote (k).
❑Inspect engine air cleaner lter. If necessary, replace
lter. SeeEngine Air Cleaner/Filter on page 5-17.
See footnote (m).
❑Rotate tires and check ination pressures and wear.
SeeTire Inspection and Rotation on page 5-65and
“Tire Wear Inspection” inAt Least Once a Month on
page 6-9.
❑Inspect brake system.See footnote (a).
❑Check engine coolant and windshield washer uid
levels and add uid as needed.
❑Perform any needed additional services.
See “Additional Required Services” in this section.
❑Inspect suspension and steering components.
See footnote (b).
❑Inspect engine cooling system.See footnote (c).
❑Inspect wiper blades.See footnote (d).
❑Inspect restraint system components.See footnote (e).
❑Lubricate body components.See footnote (f).
❑Check transmission uid level and add uid
as needed.
