Caution
Use of the incorrect transmission
fluid may damage the vehicle,
and the damage may not be
covered by the vehicle warranty.
Always use the correct
transmission fluid. See

Dual Clutch Transmission
Fluid Life System
When to Change the Dual
Clutch Transmission Fluid
This vehicle has a computer that
indicates when to change the
transmission fluid. This is based on
a combination of factors which
include temperature and miles
driven. Based on driving conditions, the mileage at which a fluid change
is indicated can vary considerably.
For the fluid life system to work
properly, the system must be reset
every time the fluid is changed.
When the system has calculated
that fluid life has been diminished, it
indicates that a fluid change is
necessary. A CHANGE
TRANSMISSION FLUID SOON
message comes on. Change the
fluid as soon as possible within the
next 1 000 km (600 mi). Failure to
change transmission fluid at
required intervals could lead to
suboptimal transmission
performance. 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.
How to Reset the Dual Clutch
Transmission Fluid Life
System
Reset the system whenever the
transmission fluid is replaced so that
the system can calculate the next
transmission fluid change.
To reset:

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 Pressure0253 and
Vehicle Load Limits 0160.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation 0256. Check that all wheel nuts are
properly tightened. See
“Wheel
Nut Torque” underCapacities
and Specifications 0299.
{Warning
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 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 a 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. Do not get grease on
the flat wheel mounting surface
or on the wheel nuts or bolts.
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 1.6 mm (1/16 in)
