Multi-point Inspection

In order to keep your vehicle running right,
it is important to have the systems on your
vehicle checked regularly. This can help
identify potential issues and prevent major
problems. We recommend having the
following multi-point inspection performed
at every scheduled maintenance interval
to help make sure your vehicle keeps
running great.

Multi-point Inspection

Horn operation

Accessory drive belt(s)

Radiator, cooler, heater and A/C hoses

Battery performance

Suspension component for leaks or

damage

Engine air filter

Steering and linkage

Exhaust system

Tires (including spare) for wear and proper

pressure

2

Exterior lamps operation

Windshield for cracks, chips or pits

Fluid levels

1

; fill if necessary

Multi-point Inspection

Be sure to ask your dealership service
advisor or technician about the multi-point
vehicle inspection. It is a comprehensive
way to perform a thorough inspection of
your vehicle. Your checklist gives you
immediate feedback on the overall
condition of your vehicle.

NORMAL SCHEDULED
MAINTENANCE

Intelligent Oil-Life Monitor™
(Diesel Engine Only)

Your diesel engine is equipped with an
Intelligent Oil-Life Monitor that determines
when you should change the engine oil
based on how your vehicle is used. By using
several important factors in its
calculations, the monitor helps reduce the
cost of owning your vehicle and reduces
environmental waste at the same time.

This means you do not have to remember
to change the oil on a mileage-based
schedule. Your vehicle lets you know when
an oil change is due by displaying a
message in the information display.

The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of
use.
