DIC Info Pages
The following is the list of all possible DIC
info displays. Depending on the vehicle,
some may not be available.
Trip 1 or 2/Average Speed/Average Fuel
Economy :Trip displays the current distance
traveled, in either kilometers (km) or
miles (mi), since the trip odometer was last
reset. The trip odometer can be reset by
pressing and holding the thumbwheel while
this display is active.
Average Speed displays the average speed of

vehicle has right now, and will change as driving conditions change. The Average Fuel
Economy can be reset by pressing and
holding the thumbwheel while this display
is active.
Oil Life :
Displays an estimate of the oil's
remaining useful life. If REMAINING OIL LIFE
99% is displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low, the
CHANGE ENGINE OIL SOON message will
appear on the display. The oil should be
changed as soon as possible. See Engine Oil
0 237. In addition to the engine oil life
system monitoring the oil life, additional
maintenance is recommended in the
Maintenance Schedule. See Maintenance
Schedule 0293.
The Oil Life display must be reset after each
oil change. It will not reset itself. Do not
reset the Oil Life display accidentally at any
time other than when the oil has just been
changed. It cannot be reset accurately until
the next oil change. To reset, see Engine Oil
Life System 0241.
Tire Pressure : Displays the approximate
pressures of all four tires. Tire pressure is
displayed in either kilopascal (kPa) or in
pounds per square inch (psi). If the pressure
is low, the value for that tire is shown in amber. See
Tire Pressure Monitor System
0 269 and
Tire Pressure Monitor Operation 0270.
Transmission Fluid Life : Displays an
estimate of the fluid's remaining useful life.
If REMAINING FLUID LIFE 99% is displayed,
that means 99% of the current fluid life
remains.
When the remaining fluid life is low, the
CHANGE TRANSMISSION FLUID SOON
message will appear on the display. The
fluid should be changed as soon as possible.
See Dual Clutch Transmission Fluid Life
System 0242. In addition to the
Transmission Fluid Life system monitoring
the fluid life, additional maintenance is
recommended in the Maintenance Schedule.

186 Driving and Operating
Load Limit
Limit vehicle load to the driver only, with no
other cargo. Inflate the front tires to 159 kPa
(23 psi) and the rear tires to 165 kPa (24 psi).
Drive at a maximum speed of 296 km/h
(184 mph).
Road Course target hot pressures of 220–
240 kPa (32–35 psi). Value will vary based on
driving style, track, temperature, and
weather conditions.
Wheel AlignmentCaution
Using these wheel alignment settings
may cause excessive tire wear. Only use
these wheel alignment settings for racing
or competitive driving. Excessive tire wear
is not covered under the vehicle
warranty.
Caution
Do not use power tools when removing
or installing the fasteners. Damage to the
threads may occur. Use hand tools only,
(Continued)
Caution (Continued)
and do not overtighten. Hand start the
fasteners to ensure that the threads do
not bind or cross thread.
The racing and competitive driving wheel
alignment settings should be set as
described here.
To achieve the track alignment specified
settings: 1. The upper control arm to body washers on all four corners will need to be
moved from between the body and the
control arm and relocated between the
head of the bolt and the control arm.
2. Adjust the lower control arm cam bolt position to achieve the following
specifications.
Front (per corner)
.Caster: +8.0 degrees
.Camber: -3.0 degrees
.Toe (total): 0.1 degrees toe in
Rear (per corner)
.Caster: 0 degrees
.Camber: -2.5 degrees
.Toe (total): 0.1 degrees toe in
.Thrust Angle: 0 degrees
After track use, reinstall washers between
the body and the control arms. Reset to
factory alignment settings. See your dealer.
Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop and
accelerate. Always drive slower in these
types of driving conditions and avoid driving
through large puddles and deep-standing or
flowing water.
{Warning
Wet brakes can cause crashes. They
might not work as well in a quick stop
and could cause pulling to one side. You
could lose control of the vehicle.
After driving through a large puddle of
water or a car/vehicle wash, lightly apply
the brake pedal until the brakes work
normally.
Flowing or rushing water creates strong
forces. Driving through flowing water
could cause the vehicle to be carried
away. If this happens, you and other (Continued)

Vehicle Care 273
SeeWhen It Is Time for New Tires 0273
and
Wheel Replacement 0277.
Different tire sizes should not be
rotated front to rear.
Use this rotation pattern if the vehicle
has different size tires on the front
and rear.
Adjust the front and rear tires to the
recommended inflation pressure on the
Tire and Loading Information label after
the tires have been rotated. See Tire
Pressure 0267 and
Vehicle Load Limits 0189. Reset the Tire Pressure Monitor System.
See
Tire Pressure Monitor Operation
0 270.
Check that all wheel nuts are properly
tightened. See “Wheel Nut Torque”
under Capacities and Specifications
0 305.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
cause wheel nuts to become loose
over time. The wheel could come off
and cause a crash. When changing a
wheel, remove any rust or dirt from
places where the wheel attaches to
the vehicle. In an emergency, a cloth
or paper towel can be used; however,
use a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the inner diameter of the
wheel hub opening with wheel bearing
grease after a wheel change or tire
rotation to prevent corrosion or rust
buildup.
{Warning
Do not apply grease to the wheel
mounting surface, wheel conical
seats, or the wheel nuts or bolts.
Grease applied to these areas could
cause a wheel to become loose or
come off, resulting in a crash.
When It Is Time for New Tires
Factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road
conditions affect the wear rate of the tires.
Treadwear indicators are one way to tell
when it is time for new tires. Treadwear
indicators appear when the tires have only

Engine Oil Change
When the CHANGE ENGINE OIL SOON
message displays, change the engine oil and
filter within the next 1 000 km (600 mi). If driven under the best conditions, the
engine oil life system may not indicate the
need for vehicle service for up to a year.
The engine oil and filter must be changed at
least once a year and the oil life system
must be reset. Your trained dealer technician
can perform this work. If the engine oil life
system is reset accidentally, service the
vehicle within 5 000 km (3,000 mi) since the
last service. Reset the oil life system when
the oil is changed. See
Engine Oil Life
System 0241.
Engine Air Filter Change
When the REPLACE AT NEXT OIL CHANGE
message displays, change the engine air
filter at the next engine oil change. When
the REPLACE ENGINE AIR FILTER SOON
message displays, the engine air filter
should be replaced at the earliest
convenience. Reset the engine air filter life
system after the engine air filter is replaced.
See Engine Air Filter Life System 0242.
Transmission Fluid Change
When the CHANGE TRANSMISSION FLUID
SOON message displays, change the fluid
and filter within the next 1 000 km (600 mi).

fluid must be changed at least every three
years and the Fluid Life System must be
reset. Your dealer has trained service
technicians who will change the fluid and
reset the system. If the system is ever reset
accidentally, the fluid must be changed at
72 000 km (45,000 mi) since the last fluid
change. SeeDual Clutch Transmission Fluid
