(Vehicle Information):The following display
menu items can be displayed by pressing the vehicle
information button:
Oil Life Remaining
If the vehicle has this display, it shows the estimated oil
life remaining. If you see 99% Oil Life Remaining on
the display, that means that 99% of the current oil life
remains.
When the oil life is depleted, the Change Engine Oil
Soon message appears on the display. You should
change the oil as soon as possible. In addition to the
engine oil life system monitoring the oil life, additional
maintenance is recommended in the Maintenance
Schedule in this manual. SeeScheduled Maintenance
on page 6-4andEngine Oil on page 5-18.The Oil Life must be reset after each oil change.
It does not reset itself. Avoid accidental resetting of the
Oil Life system. It cannot be reset accurately until
the next oil change. To reset the engine oil life system,
SeeEngine Oil Life System on page 5-21. The display
shows 100% when the system is reset.
Units
This display allows you to select between English or
Metric units of measurement. Once in this display,
press the set/reset button to select between English or
Metric units.
Parking Assist
If the vehicle has the Ultrasonic Rear Parking Assist
(URPA) 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. The URPA
system automatically turns back on after each vehicle
start. When the URPA system is turned off and the
vehicle is shifted out of P (Park), the DIC displays the
Parking Assist Off message as a reminder that the
system has been turned off. SeeDIC Warnings
and Messages on page 3-58andUltrasonic Rear
Parking Assist (URPA) on page 2-54for more
information.

This message displays when calibrating the compass.
Drive the vehicle in circles at less than 5 mph (8 km/h)
to complete the calibration. SeeDIC Compass on
page 3-56for more information.
Calibration Complete
This message displays when the compass calibration is
complete. SeeDIC Compass on page 3-56for more
information.
Change Engine Oil Soon
When this message displays, it means that service is
required for the vehicle. See your dealer/retailer.
SeeEngine Oil on page 5-18andScheduled
Maintenance on page 6-4for more information.
When you reset the Change Engine Oil Soon message
by clearing it from the display, you still must reset
the engine oil life system separately. For more
information on resetting the engine oil life system,
seeEngine Oil Life System on page 5-21.
Check Tire Pressure
This message displays when the pressure in one or
more of the vehicle’s tires needs to be checked. It also
displays Left Front, Right Front, Left Rear, or Right
Rear to indicate which tire. More than one tire pressure
message can be received at a time. To read the
other messages, press the set/reset button. If a tire
pressure message appears, 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 5-61,Loading the Vehicle on page 4-20, and
Inflation - Tire Pressure on page 5-69. The DIC display
also shows the tire pressure values. SeeDIC
Operation and Displays on page 3-51. If the tire
pressure is low, the low tire pressure warning light
comes on. SeeTire Pressure Light on page 3-42.
Cruise Set To XXX MPH (km/h)
This message displays whenever the cruise control

How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface.
If the level is below the bottom of the ller plug hole,
located on the rear axle, you’ll need to add some
lubricant. Add enough lubricant to raise the level to the
bottom of the ller plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeeRecommended Fluids
and Lubricants on page 6-14.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory and
should need no further adjustment.
However, if the vehicle is damaged in a crash, the
headlamp aim may be affected and adjustment may be
necessary.
If oncoming vehicles ash their high beams at you, this
may also mean the vertical aim needs to be adjusted.

Reset the Tire Pressure Monitor System. SeeTire
Pressure Monitor Operation on page 5-73.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-127.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause a crash. 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 you
need to, to get all the rust or dirt off.
When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions
inuence when you need new tires.
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining.

The proper replacement parts, uids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 6-14andMaintenance Replacement Parts
on page 6-16. When the vehicle is serviced, make sure
these are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of genuine
parts from your dealer/retailer.
Scheduled Maintenance
To maintain the ride, handling, and performance
of this 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 5-61.
Rotate tires. SeeTire Inspection and Rotation on
page 5-76and “Tire Wear Inspection” inAt Least
Once a Month on page 6-11.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 5-21for information on the Engine
Oil Life System and resetting the system.
