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 0221.
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 0224.
Transmission Fluid Change
When the CHANGE
TRANSMISSION FLUID SOON
message displays, change the fluid
and filter within the next 1 000 km
(600 mi). Failure to change the
transmission fluid at required
intervals can lead to reduced transmission performance. The
transmission 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. See
