SERVICING AND MAINTENANCE
SCHEDULED SERVICING — GASOLINE
ENGINE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures will influence when the “Change
Oil” or “Oil Change Required” message is displayed. Have
your vehicle serviced as soon as possible, within the next
500 miles (805 km).On vehicles equipped with instrument cluster display, “Oil
Change Required” will be displayed and a single chime will
sound, indicating that an oil change is necessary.
On non-instrument cluster display equipped vehicles,
“Change Oil” will flash in the instrument cluster odometer
and a single chime will sound, indicating that an oil
change is necessary.
An authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
an authorized dealer, the message can be reset by
referring to the steps described under Instrument Cluster
Display for further information
Úpage 108.
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.
Once A Month Or Before A Long Trip:

Check the engine oil level.
 Check the windshield washer fluid level.
 Check the tire inflation pressures and look for unusual
wear or damage, rotate at the first sign of irregular
wear.
 Check the fluid levels of the coolant reservoir, brake
master cylinder, and power steering, and fill as needed.
 Check the function of all interior and exterior lights.

Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire; however, the date code may only be on one side. Tires with white sidewalls will have the full TIN, including the date code, located
on the white sidewall side of the tire. Look for the TIN on the outboard side of black sidewall tires as mounted on the vehicle. If the TIN is not found on the outboard side, then you will
find it on the inboard side of the tire.Service Description:
95
= Load Index
 A numerical code associated with the maximum load a tire can carry
H = Speed Symbol
 A symbol indicating the range of speeds at which a tire can carry a load corresponding to its load index under certain operating conditions
 The maximum speed corresponding to the speed symbol should only be achieved under specified operating conditions (i.e., tire pressure, vehicle loading, road conditions, and
posted speed limits)
Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL) tire:
 XL = Extra load (or reinforced) tire, or
 LL = Light load tire or
 C, D, E, F, G = Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load – Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure – Maximum pressure indicates the maximum permissible cold tire inflation pressure for this tire
EXAMPLE:
EXAMPLE:
DOT MA L9 ABCD 0301
DOT = Department of Transportation
 This symbol certifies that the tire is in compliance with the US Department of Transportation tire safety standards and is approved for highway use
MA = Code representing the tire manufacturing location (two digits)
L9 = Code representing the tire size (two digits)
ABCD = Code used by the tire manufacturer (one to four digits)
