RECREATIONAL TOWING (BEHIND MOTORHOME, ETC.)
Towing This Vehicle Behind Another Vehicle
Recreational Towing
Recreational towing is allowed ONLY if the front
wheels are OFF the ground. This may be accom -
plished 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 instruc -
tions.
2. Drive the front wheels onto the tow dolly. 3. Firmly apply the parking brake. Place the
transmission in PARK.
4. Properly secure the front wheels to the dolly, following the dolly manufacturer's
instructions.
5. Release the parking brake.
Towing Condition Wheels OFF the Ground Automatic Transmission
Flat TowNONE NOT ALLOWED

On Trailer ALL OK
NOTE:
When towing your vehicle, always follow applicable state and provincial laws. Contact state and provincial Highway Safety offices for additional details.
CAUTION!
DO NOT flat tow this vehicle. Damage to the
drivetrain will result. If this vehicle requires
towing, make sure the drive wheels are OFF
the ground.
Towing this vehicle in violation of the above
requirements can cause severe transmis -
sion damage. Damage from improper
towing is not covered under the New
Vehicle Limited Warranty.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change indi-
cator 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 in the
instrument cluster. 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. Severe Operating Condi-
tions can cause the change oil message to illu -
minate as early as 3,500 miles (5,600 km)
since last reset. Have the 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 sched
-
uled oil change. If a scheduled oil change is
performed by someone other than an autho -
rized dealer, the message can be reset by refer -
ring to the steps described under “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
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.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) or
350 hours of engine run time if the vehicle is
operated in a dusty and off road environment or
is operated predominately at idle or only very
low engine RPM. 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. Rotate at the
first sign of irregular wear, even if it occurs
before the oil indicator system turns on
Check the fluid levels of the coolant reservoir,
brake master cylinder, and power steering
and fill as needed
Check function of all interior and exterior
lights
Maintenance Plan
Required Maintenance Intervals
Refer to the maintenance plan on the following
pages for the required maintenance intervals.

174SERVICING AND MAINTENANCE
Loading
The vehicle maximum load on the tire must not
exceed the load carrying capacity of the tire on
your vehicle. You will not exceed the tire's load
carrying capacity if you adhere to the loading
conditions, tire size, and cold tire inflation pres -
sures specified on the Tire and Loading Infor -
mation placard in “Vehicle Loading” in the
“Starting And Operating” section of this manual.
NOTE:
Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front
and rear axles must not be exceeded.
For further information on GAWRs, vehicle
loading, and trailer towing, refer to “Vehicle
Loading” in the “Starting And Operating”
section of this manual.
To determine the maximum loading conditions
of your vehicle, locate the statement “The
combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs” on the
Tire and Loading Information placard. The
combined weight of occupants, cargo/luggage
and trailer tongue weight (if applicable) should
never exceed the weight referenced here. Steps For Determining Correct Load Limit—
(1) Locate the statement “The combined weight
of occupants and cargo should never exceed
XXX kg or XXX lbs.” on your vehicle's placard.
(2) Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
(3) Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.
(4) The resulting figure equals the available
amount of cargo and luggage load capacity. For
example, if “XXX” amount equals 1400 lbs. and
there will be five 150 lb passengers in your
vehicle, the amount of available cargo and
luggage load capacity is 650 lbs. (1400-750
(5x150) = 650 lbs.)
(5) Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated in
Step 4.
(6) If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity of your vehicle.Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg
and there will be five 68 kg passengers in your
vehicle, the amount of available cargo and
luggage load capacity is 295 kg (635-340
(5x68) = 295 kg) as shown in step 4.
NOTE:
If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. The following table shows examples
on how to calculate total load, cargo/
luggage, and towing capacities of your
vehicle with varying seating configurations
and number and size of occupants. This table
is for illustration purposes only and may not
be accurate for the seating and load carry
capacity of your vehicle.
For the following example, the combined
weight of occupants and cargo should never
exceed 865 lbs (392 kg).

178SERVICING AND MAINTENANCE
Radial Ply Tires
Tire Repair
If your tire becomes damaged, it may be
repaired if it meets the following criteria:
The tire has not been driven on when flat.
The damage is only on the tread section of
your tire (sidewall damage is not repairable).
The puncture is no greater than a ¼ of an
inch (6 mm).
Consult an authorized tire dealer for tire repairs
and additional information. Damaged Run Flat tires, or Run Flat tires that
have experienced a loss of pressure should be
replaced immediately with another Run Flat tire
of identical size and service description (Load
Index and Speed Symbol). Replace the tire pres
-
sure sensor as well as it is not designed to be
reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after a
rapid loss of inflation pressure. This rapid loss
of inflation is referred to as the Run Flat mode.
A Run Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has
limited driving capabilities and needs to be
replaced immediately. A Run Flat tire is not
repairable. When a run flat tire is changed after
driving with underinflated tire condition, please
replace the TPM sensor as it is not designed to
be reused when driven under run flat mode 14
psi (96 kPa) condition.
NOTE:
TPM Sensor must be replaced after driving the
vehicle on a flat tire condition. It is not recommended driving a vehicle loaded
at full capacity or to tow a trailer while a tire is in
the run flat mode.
See the tire pressure monitoring section for
more information.
Tire Spinning

When stuck in mud, sand, snow, or ice condi
-
tions, do not spin your vehicle's wheels
above 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping.

Refer to “Freeing A Stuck Vehicle” in “In Case Of
Emergency” for further information.
WARNING!
Combining radial ply tires with other types of
tires on your vehicle will cause your vehicle to
handle poorly. The instability could cause a
collision. Always use radial ply tires in sets of
four. Never combine them with other types of
tires.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause tire damage or failure. A
tire could explode and injure someone. Do
not spin your vehicle's wheels faster than
30 mph (48 km/h) for more than 30
seconds continuously when you are stuck,
and do not let anyone near a spinning
wheel, no matter what the speed.
