mode.
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels faster
than 30 mph (48 km/h) or for longer than 30 seconds
continuously without stopping when you are stuck and
do not let anyone near a spinning wheel, no matter what
the speed.
CAUTION!
• When “rocking” a stuck vehicle by shifting between DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.

• Revving the engine or spinning the wheels too fast may lead to transmission overheating and failure. It can also damage
the tires. Do not spin the wheels above 30 mph (48 km/h)
while in gear (no transmission shifting occurring).

IN CASE OF EMERGENCY 239
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other equip-
ment designed for this purpose, following equipment manu-
facturer’s instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main structural
members of the vehicle, not to bumpers or associated
brackets. State and local laws regarding vehicles under tow
must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode.
If the ignition key is unavailable, or the vehicle's battery is
discharged, refer to “Gear Selector Override” in this section
for instructions on shifting the transmission out of PARK (P)
for towing. The manufacturer recommends towing your vehicle with all
four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, this vehicle must be
towed with the front wheels OFF the ground (using a towing
dolly, or wheel lift equipment with the front wheels raised).
CAUTION!
• Do not use sling type equipment when towing. Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do not attach to front or rear suspension components. Damage
to your vehicle may result from improper towing.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe transmission 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 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 indi-
cator message will illuminate. This means that service is
required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extended engine idle time,
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 “Oil
Change Reset” in “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), 350 hours of engine run time or
12 months, 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 environ -
ment or is operated predominantly 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 tire pressure and look for unusual wear or damage. Rotate tires 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 and brake master cylinder, fill as needed.
• Check function of all interior and exterior lights.

246 SERVICING AND MAINTENANCE
Checking Oil Level
To ensure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at regular
intervals, such as every fuel stop. The best time to check the
engine oil level is about five minutes after a fully warmed up
engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings.
There are four possible dipstick types,
• Crosshatched zone.
• Crosshatched zone marked SAFE.
• Crosshatched zone marked with MIN at the low end of therange and MAX at the high end of the range.
• Crosshatched zone marked with dimples at the MIN and the MAX ends of the range. NOTE:
Always maintain the oil level within the crosshatch mark
-
ings on the dipstick.
Adding 1 quart (1.0 liters) of oil when the reading is at the
low end of the dipstick range will raise the oil level to the
high end of the range marking.
Adding Washer Fluid

The windshield and rear window washers share the same fluid
reservoir. The fluid reservoir is located in the front of the engine
compartment. Be sure to check the fluid level in the reservoir at
regular intervals. Fill the reservoir with windshield washer
solvent (not radiator antifreeze) and operate the system for a
few seconds to flush out the residual water.

When refilling the washer fluid reservoir, take some washer
fluid and apply it to a cloth or towel and wipe clean the
wiper blades, this will help blade performance. CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage your
engine.

(Continued)
To minimize the possibility of catalytic converter damage:
• Do not interrupt the ignition when the transmission is ingear and the vehicle is in motion.
• Do not try to start the vehicle by pushing or towing the vehicle.
• Do not idle the engine with any ignition components disconnected or removed, such as when diagnostic testing,
or for prolonged periods during very rough idle or
malfunctioning operating conditions.
Cooling System
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty, the
system should be drained, flushed, and refilled with fresh
OAT coolant (conforming to MS.90032) by an authorized
dealer. Check the front of the A/C condenser for any accu-
mulation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the face
of the condenser.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of the connection at the
coolant recovery bottle and radiator. Inspect the entire
system for leaks. DO NOT REMOVE THE COOLANT PRES -
SURE CAP WHEN THE COOLING SYSTEM IS HOT.
WARNING!
• You or others can be badly burned by hot engine coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never open a cooling system pressure cap when the
radiator or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry away from the radiator cooling fan when the hood is raised. The fan
starts automatically and may start at any time, whether
the engine is running or not.
• When working near the radiator cooling fan, discon -
nect the fan motor lead or turn the ignition to the OFF
mode. The fan is temperature controlled and can start at
any time the ignition is in the ON mode.

Tire And Loading Information PlacardTire And Loading Information Placard
This placard tells you important information about the:
1. Number of people that can be carried in the vehicle.
2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear, and spare tires. 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 Information 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” chapter of this manual.
To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of occu-
pants 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 refer -
enced here.

Steps For Determining Correct Load Limit—
(1) Locate the statement “The combined weight of occu-
pants 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 avail
-
able 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 occu -
pants and cargo should never exceed 865 lbs (392 kg).

SERVICING AND MAINTENANCE 279
Consult an authorized tire dealer for tire repairs and addi-
tional information.
Damaged Run Flat tires, or Run Flat tires that have experi -
enced 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
pressure 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” in the “Safety” chapter for
more information.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, 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 Emer
-
gency” for further information.
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.
