When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or 500 mi
(800 km) of the message appearing. Make
sure you reset the Intelligent Oil-Life
Monitor after each oil change. See
Oil
Change Indicator Reset (page 356).
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or
5,000 mi (8,000 km) from
your last oil change. Never exceed one year
or
10,000 mi (16,000 km) between oil
change intervals.
You can drive high performance vehicles
in such a way that may lead to higher oil
consumption this includes extended time
at high engine speeds, high loads, engine
braking, hard cornering maneuvers, track
and off-road usage. Under these
conditions, oil consumption of
approximately 1 quart per 500 miles (1 liter
per 800 km) is possible. As a result, you
need to check the engine oil level at every
refueling and adjust to maintain proper
levels to avoid engine damage.
Your vehicle is very sophisticated and built
with multiple, complex, performance
systems. Every manufacturer develops
these systems using different
specifications and performance features.
That is why it is important to rely upon your
dealership to properly diagnose and repair
your vehicle.
We have recommended maintenance
intervals for various parts and component
systems based upon engineering testing.
We rely upon this testing to determine the
most appropriate mileage for replacement
of oils and fluids to protect your vehicle at
the lowest overall cost to you and
recommends against maintenance
schedules that deviate from the scheduled
maintenance information. We strongly recommend the use of only
our genuine or our authorized
re-manufactured replacement parts
engineered for your vehicle.
Additives and Chemicals
This owner's manual and our Workshop
Manual list the recommended additives
and chemicals for your vehicle. We do not
recommend using chemicals or additives
not approved by us as part of your vehicle
’s
normal maintenance. Please consult your
warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. However, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
Make sure to change your vehicle ’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using our approved flushing
chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.
