SUMMER/THREE-SEASON TIRES
• This vehicle may be equipped with wheels and tires to enhance traction in bothwet and dry conditions.
• Summer tires are not intended to be driven in snow or on ice.

Summer tires will not contain the all season designation or mountain/snowflake
symbol on the sidewall of the tire.
WARNING!
Do not use summer tires in snow/ice conditions. You could lose control, resulting
in severe injury or death. Driving too fast for conditions also creates the possibility
of loss of vehicle control.

DIESEL ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due to its construction. Normal
operation is allowed, providing the following recommendations are followed:
• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significantweight.
NOTE:
Light duty operation such as light trailer towing or no load operation will extend the
time before the engine is at full efficiency. Reduced fuel economy and power may be
seen at this time.
The engine oil installed in the engine at the factory is a high-quality energy
conserving type lubricant. Oil changes should be consistent with anticipated climate
conditions under which vehicle operations will occur. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.
DIESEL ENGINE STARTING PROCEDURES
Normal Starting Procedure
1. Apply the parking brake.
2. Ensure the gear selector is in the PARK position.
3. Press and hold the brake pedal while pushing the ENGINE START/STOP button once and the system will engage the starter to crank the engine.
NOTE: • A delay of the start of up to five seconds is possible under very cold conditions.The “Wait to Start” telltale will be illuminated during the pre-heat process,
When the engine Wait To Start light goes off the engine will automatically crank.
• If you wish to stop the cranking of the engine prior to the engine starting, push the button again.
4. Check that the oil pressure warning light has turned off.
5. Release the parking brake.

INSTRUMENT CLUSTER WARNING LIGHTS
– Battery Charge Warning Light
This light illuminates when the battery is not charging properly. If the battery charge
warning light remains on, it means that the vehicle is experiencing a problem with the
charging system.
We recommend you do not continue driving if it is on. Have the vehicle serviced
immediately.
– Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. A chime will sound for four
minutes when this light turns on.
We recommend you do not operate the vehicle or engine damage will occur. Have the
vehicle serviced immediately.
– Engine Temperature Warning Light
This light warns of an overheated engine condition.
If the light turns on and a warning chime sounds while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the temperature reading does not return to normal,
turn the engine off immediately.
We recommend that you do not operate the vehicle or engine damage will occur. Have
the vehicle serviced immediately.
WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned by
steam or boiling coolant.
WHAT TO DO IN EMERGENCIES
189

Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the vehicle is operated in a dusty
and off road environment or is operated predominately at idle or only very low engine
RPM’s. This type of vehicle use is considered Severe Duty.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual wear or damage
• Check the fluid levels of the coolant reservoir, brake master cylinder and fill asneeded.
• Check function of all interior and exterior lights
Required Maintenance
Refer to the Maintenance Schedules on the following pages for required mainte-
nance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil
indicator system turns on.
• Inspect battery and clean and tighten terminals as required.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.

MAINTENANCE SCHEDULE — DIESEL 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 “Oil Change Required” message is displayed. Severe
Operating Conditions can cause the change oil message to illuminate as early as
3,500 miles (5,600 km) since last reset. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).
Your 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 your authorized dealer, the message can be reset by referring to the steps
described under “Instrument Cluster Warning Lights” in “What To Do In Emergen-
cies” in this guide or “Driver Information Display (DID)” in “Understanding Your
Instrument Panel” in your Owners Manual on the DVD for further information.
NOTE:
Under no circumstances should oil change intervals exceed 10,000 miles
(16,000 km) or twelve months, whichever comes first.
Engine Oil Filter Replacement
Residual oil in the housing may spill from the housing when the new filter is installed
if the residual oil is not either removed from the housing or enough time has not
elapsed to allow the oil to drain back into the engine. When servicing the oil filter on
this engine, carefully remove the filter and use a suction gun to remove any residual
oil left in the housing or wait about 30 minutes for the oil to drain back into the
engine.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual wear or damage
• Check the fluid levels of the coolant reservoir, brake master cylinder, and fill asneeded
• Check function of all interior and exterior lights
