Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer up in an area away from heavy
traffic.
Automatic Transmission
The “DRIVE” range can be selected when towing. The
transmission controls include an adaptive drive strategy
to avoid frequent shifting when towing. However, if
frequent shiftingdoes occur while in DRIVE, select
“TOW/HAUL” mode or select a lower gear using the
Electronic Range Select (ERS) switches.
NOTE:Using “TOW/HAUL” mode or a lower gear
range while operating the vehicle under heavy loading
conditions will improve performance and extend trans-
mission life by reducing excessive shifting and heat build
up. This action will also provide better engine braking.

NOTE:Vehicles equipped with air suspension must be
lowered to the “Entry/Exit” (lowest) level, and have
automatic leveling disabled, before tying them down
(from the body) on a trailer or flatbed truck. Refer to “Air
Suspension – If Equipped” for more information. If the
vehicle cannot be lowered to the “Entry/Exit” level (for
example, engine will not run), tie-downs must be fas-
tened to the axles (not to the body). Failure to follow
these instructions may cause fault codes to be set and/or
cause loss of proper tie-down tension.
Recreational Towing – Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for two-wheel drive models) is
allowed ONLYif the rear wheels are OFFthe ground.
This may be accomplished using a tow dolly or vehicle
trailer. If using a tow dolly, follow this procedure: 1. Properly secure the dolly to the tow vehicle, following
the dolly manufacturer’s instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Place automatic trans- mission in PARK, manual transmission in gear (not in
NEUTRAL).
4. Properly secure the rear wheels to the dolly, following the dolly manufacturer’s instructions.
5. Remove the key fob from the ignition switch.
6. Install a suitable clamping device, designed for tow- ing, to secure the front wheels in the straight position.

MAINTENANCE SCHEDULE
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 ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel usage 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 thanyour authorized dealer, the message can be reset by refer-
ring to the steps described under “Electronic Vehicle Infor-
mation Center (EVIC)/Oil Change Required” in “Under-
standing Your Instrument Panel” for further information.
NOTE:
Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
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, power steering (2500/3500 Models
Only) and transmission as needed
• Check function of all interior and exterior lights
