Pressure Washing
DEALER SERVICE
An authorized dealer has the qualified service personnel,
special tools, and equipment to perform all service opera-
tions in an expert manner. Service Manuals are available
which include detailed service information for your vehicle.
Refer to these Service Manuals before attempting any proce -
dure yourself.
NOTE:
Intentional tampering with emissions control systems may
void your warranty and could result in civil penalties being
assessed against you.
Engine Oil
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance. Refer
to the “Maintenance Plan” in this chapter for further infor -
mation.
NOTE:
Under no circumstances should oil change intervals exceed
10,000 miles (16,000 km), 12 months or 350 hours of engine
run time, whichever comes first. The 350 hours of engine run
or idle time is generally only a concern for fleet customers.
CAUTION!
Cleaning the engine compartment with a high pressure
washer is not recommended. Precautions have been
taken to safeguard all parts and connections however,
the pressures generated by these machines is such that
complete protection against water ingress cannot be
guaranteed.
WARNING!
You can be badly injured working on or around a motor
vehicle. Only do service work for which you have the
knowledge and the proper equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.

SERVICING AND MAINTENANCE 251
Air Conditioner Maintenance
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the start
of each warm season. This service should include cleaning of
the condenser fins and a performance test. Drive belt tension
should also be checked at this time.Refrigerant Recovery And Recycling — R–1234yf
R–1234yf Air Conditioning Refrigerant is a hydrofluo-
roolefin (HFO) that is endorsed by the Environmental
Protection Agency and is an ozone-friendly substance with a
low global-warming potential. The manufacturer recom -
mends that air conditioning service be performed by an
authorized dealer using recovery and recycling equipment.
NOTE:
Use only manufacturer approved A/C system PAG
compressor oil, and refrigerants.
WARNING!
• Use only refrigerants and compressor lubricants approved by the manufacturer for your air condi -
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other unap -
proved refrigerants or lubricants can cause the system
to fail, requiring costly repairs. Refer to Warranty Infor -
mation Book, for further warranty information.
• The air conditioning system contains refrigerant under high pressure. To avoid risk of personal injury or
damage to the system, adding refrigerant or any repair
requiring lines to be disconnected should be done by
an experienced technician.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air
conditioning components. Such damage is not covered
by the New Vehicle Limited Warranty.

280 SERVICING AND MAINTENANCE
Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be replaced.
These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes a 1/16 of an inch (1.6 mm). When the tread is worn
to the tread wear indicators, the tire should be replaced.
Refer to “Replacement Tires” in this section for further infor-
mation.
Life Of Tire
The service life of a tire is dependent upon varying factors
including, but not limited to:
• Driving style.
• Tire pressure - Improper cold tire inflation pressures can cause uneven wear patterns to develop across the tire
tread. These abnormal wear patterns will reduce tread life,
resulting in the need for earlier tire replacement.
• Distance driven.
• Performance tires, tires with a speed rating of V or higher, and Summer tires typically have a reduced tread life. Rota -
tion of these tires per the vehicle scheduled maintenance is
highly recommended. NOTE:
Wheel Valve Stem must be replaced as well when installing
new tires due to wear and tear in existing tires.
Keep dismounted tires in a cool, dry place with as little expo
-
sure to light as possible. Protect tires from contact with oil,
grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for wear
and correct cold tire inflation pressures. The manufacturer
strongly recommends that you use tires equivalent to the
originals in size, quality and performance when replacement
is needed. Refer to the paragraph on “Tread Wear Indica -
tors” in this section. Refer to the Tire and Loading Informa -WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to follow
this warning can result in sudden tire failure. You could
lose control and have a collision resulting in serious
injury or death.
