(Continued)
Lights     
Have someone observe the operation of brake 
lights and exterior lights while you work the 
controls. Check turn signal and high beam 
indicator lights on the instrument panel.
Door Latches 
Check for proper closing, latching, and locking.
Fluid Leaks  
Check area under the vehicle after overnight 
parking for fuel, coolant, oil, or other fluid leaks. 
Also, if gasoline fumes are detected or if fuel or 
brake fluid leaks are suspected, the cause should 
be located and corrected immediately.
EXHAUST GAS    
The best protection against carbon monoxide entry 
into the vehicle body is a properly maintained 
engine exhaust system.
Whenever a change is noticed in the sound of the 
exhaust system, when exhaust fumes can be 
detected inside the vehicle, or when the underside 
or rear of the vehicle is damaged, have an 
authorized dealer inspect the complete exhaust 
system and adjacent body areas for broken, 
damaged, deteriorated, or mispositioned parts. 
Open seams or loose connections could permit 
exhaust fumes to seep into the passenger 
compartment. In addition, inspect the exhaust 
system each time the vehicle is raised for 
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS  
WARNING!
Exhaust gases can injure or kill. They contain 
carbon monoxide (CO), which is colorless and 
odorless. Breathing it can make you 
unconscious and can eventually poison you. To 
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in 
confined areas any longer than needed to 
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift -
gate/rear doors open, make sure that all 
windows are closed and the climate control 
BLOWER switch is set at high speed. DO NOT 
use the recirculation mode.
If it is necessary to sit in a parked vehicle with 
the engine running, adjust your heating or 
cooling controls to force outside air into the 
vehicle. Set the blower at high speed.
WARNING!
WARNING!
Carbon monoxide (CO) in exhaust gases is 
deadly. Follow the precautions below to prevent 
carbon monoxide poisoning:
Do not inhale exhaust gases. They contain 
carbon monoxide, a colorless and odorless 
gas, which can kill. Never run the engine in a 
closed area, such as a garage, and never sit in 
a parked vehicle with the engine running for 
an extended period. If the vehicle is stopped in 
an open area with the engine running for more 
than a short period, adjust the ventilation 
system to force fresh, outside air into the 
vehicle.
Guard against carbon monoxide with proper 
maintenance. Have the exhaust system 
inspected every time the vehicle is raised. 
Have any abnormal conditions repaired 
promptly. Until repaired, drive with all side 
windows fully open.

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, and extremely hot or cold ambient 
temperatures will influence when the “Oil Change 
Required” message is displayed. Have your vehicle 
serviced as soon as possible, within the next 
500 miles (805 km).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  
Ú
page 114.
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 engine oil level.
Check windshield washer fluid level.
Check tire pressure and look for unusual wear 
or damage. Rotate tires at the first sign of irreg
-
ular wear, even if it occurs before the oil indi -
cator system turns on.
Check the fluid levels of the coolant reservoir, 
brake master cylinder, and fill as needed.
Check function of all interior and exterior lights.
