WARNING!
You can be badly injured working on or
around a motor vehicle. Do only service
work for which you have the knowledge and
the right equipment. If you have any doubt
about your ability to perform a service job,
take your vehicle to a competent mechanic.Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an acci -
dent.
WARNING! (Continued)CAUTION!
***The manufacturer highly recommends
that all cooling system service, maintenance,
and repairs be performed by your local
authorized dealer.

Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever
necessary, install ONLY the correct type ther -
mostat. Other designs may result in unsatis -
factory engine coolant (antifreeze)
performance, poor gas mileage, and
increased emissions.
Charge Air Cooler — Inter-Cooler
The charge air cooler is positioned below the
radiator and the air conditioner condenser. Air
enters the engine through the air cleaner and
passes through the turbocharger, where it is
pressurized. This pressurized air rapidly
reaches high temperature. The air is then
directed through a hose to the charge air cooler
and through another hose to the intake mani -
fold of the engine. The air entering the engine
has been cooled by about 50° to 100°F (10° to
38°C). This cooling process enables more effi -
cient burning of fuel resulting in fewer emis -
sions.
To guarantee optimum performance of the
system, keep the surfaces of the charge air
cooler, condenser and radiator clean and free of debris. Periodically check the hoses leading
to and from the charge air cooler for cracks or
loose clamps resulting in loss of pressure and
reduced engine performance.
Brake System
In order to ensure brake system performance,
all brake system components should be
inspected periodically. Refer to the “Mainte
-
nance Plan” in this section for the proper main -
tenance intervals.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood
service or immediately if the brake system
warning lamp indicates system failure. If necessary, add fluid to bring level within the
designated marks on the side of the reservoir of
the brake master cylinder. Be sure to clean the
top of the master cylinder area before removing
cap.
With disc brakes the fluid level can be expected
to fall as the brake linings wear. However, an
unexpected drop in fluid level may be caused by
a leak and a system check should be
conducted.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your foot
resting or riding on the brake pedal can result
in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.WARNING!
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri
-
cants” in “Technical Specifications” for
further information. Using the wrong type of
brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory
installed hydraulic master cylinder reser -
voir.

NOTE:
P (Passenger) — Metric tire sizing is based on
US design standards. P-Metric tires have the
letter “P” molded into the sidewall preceding
the size designation. Example: P215/65R15
95H.
European — Metric tire sizing is based on
European design standards. Tires designed
to this standard have the tire size molded
into the sidewall beginning with the section
width. The letter "P" is absent from this tire
size designation. Example: 215/65R15 96H.

CUSTOMER ASSISTANCE
SUGGESTIONS FOR OBTAINING SERVICE
FOR YOUR VEHICLE
Prepare For The Appointment
If you are having warranty work done, be sure to
have the right papers with you. Take your
warranty folder. All work to be performed may
not be covered by the warranty. Discuss addi-
tional charges with the service manager. Keep a
maintenance log of your vehicle's service
history. This can often provide a clue to the
current problem.
Prepare A List
Make a written list of your vehicle's problems or
the specific work you want done. If you've had
an accident or work done that is not on your
maintenance log, let the service advisor know.
Be Reasonable With Requests
If you list a number of items and you must have
your vehicle by the end of the day, discuss the
situation with the service advisor and list the
items in order of priority. At many authorized
dealers, you may obtain a rental vehicle at a minimal daily charge. If you need a rental, it is
advisable to make these arrangements when
you call for an appointment.
IF YOU NEED ASSISTANCE
The manufacturer and its authorized dealers
are vitally interested in your satisfaction. We
want you to be happy with our products and
services.
Warranty service must be done by an autho
-
rized dealer. We strongly recommend that you
take the vehicle to an authorized dealer. They
know your vehicle the best, and are most
concerned that you get prompt and high quality
service. The manufacturer's authorized dealers
have the facilities, factory-trained technicians,
special tools, and the latest information to
ensure the vehicle is fixed correctly and in a
timely manner.
This is why you should always talk to an autho -
rized dealer service manager first. Most matters
can be resolved with this process.
If for some reason you are still not satisfied,
talk to the general manager or owner of the
authorized dealer. They want to know if you
need assistance.
If an authorized dealer is unable to resolve
the concern, you may contact the manufac -
turer's customer center.
Any communication to the manufacturer's
customer center should include the following
information:
Owner's name and address
Owner's telephone number (home, mobile,
and office)
Authorized dealer name
Vehicle Identification Number (VIN)
Vehicle delivery date and mileage
