360SERVICING AND MAINTENANCE
When inspecting accessory drive belts, small
cracks that run across ribbed surface of belt from
rib to rib, are considered normal. These are not a
reason to replace belt. However, cracks running
along a rib (not across) are not normal. Any belt
with cracks running along a rib must be replaced.
Also have the belt replaced if it has excessive wear,
frayed cords or severe glazing.

Accessory Belt (Serpentine Belt)

Conditions that would require replacement:
Rib chunking (one or more ribs has separated
from belt body)
Rib or belt wear
Longitudinal belt cracking (cracks between two
ribs)
Belt slips
Groove jumping (belt does not maintain correct
position on pulley)
Belt broken (identify and correct problem before
new belt is installed)
Noise (objectionable squeal, squeak, or rumble
is heard or felt while drive belt is in operation)
Some conditions can be caused by a faulty
component such as a belt pulley. Belt pulleys
should be carefully inspected for damage and
proper alignment.
Belt replacement on some models requires the
use of special tools, we recommend having your
vehicle serviced at an authorized dealer.
DRAINING FUEL/WATER SEPARATOR
F
ILTER
There are two fuel filter assemblies. One is located
on the driver's side of the engine. The best access
to this water drain valve is from under the hood.
The second one is on the under body, located in
front of the rear axle above the drive shaft on
pick-up models. The second filter location is on the
frame behind the front axle. The best access to this
water drain valve is from under the vehicle. If water is detected in the water separator while the
engine is running, or while the ignition switch is in
the ON position, the Water In Fuel Indicator Light
will illuminate and an audible chime will be heard
five times. At this point you should stop the engine
and drain the water from both of the filters.
If the Water In Fuel Indicator Light comes on and a
single chime is heard while you are driving, or with
the ignition switch in the ON position, there may be
a problem with your water separator wiring or
sensor. See an authorized dealer for service.
CAUTION!
Do not drain the fuel/water separator filter
when the engine is running.
Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appropriate
container.
CAUTION!
If the Water In Fuel Indicator Light remains on,
DO NOT START the engine before you drain water
from the fuel filters to avoid engine damage.

Tire Loading And Tire Pressure
NOTE:The proper cold tire inflation pressure is listed on
the driver’s side B-pillar or the rear edge of the
driver's side door.
Check the inflation pressure of each tire, including
the spare tire (if equipped), at least monthly and
inflate to the recommended pressure for your
vehicle.

Example Tire Placard Location (Door) Example Tire Placard Location (B-pillar)

Tire And Loading Information Placard

Tire 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 pressures specified
on the Tire And Loading Information Placard
Úpage 180.
NOTE:Under a maximum loaded vehicle condition, gross
axle weight ratings (GAWR) for the front and rear
axles must not be exceeded.
For further information on GAWR, vehicle loading,
and trailer towing Ú page 180.

23_DPF_OM_EN_USC_t.book Page 394

SERVICING AND MAINTENANCE395
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 occu
-
pants. 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).

TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Four primary areas are affected by improper tire
pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation affect the
stability of the vehicle and can produce a feeling of
sluggish response or over responsiveness in the
steering.
NOTE:
Unequal tire pressures from side to side may
cause erratic and unpredictable steering
response.
Unequal tire pressure from side to side may
cause the vehicle to drift left or right.Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause
abnormal wear patterns and reduced tread life,
resulting in the need for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable
ride. Overinflation produces a jarring and
uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on
the driver's side B-pillar or rear edge of the driver's
side door.
At least once a month:
Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgment when determining
proper inflation. Tires may look properly inflated
even when they are underinflated.
Inspect tires for signs of tire wear or visible
damage.
WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect vehicle
handling, and increase your stopping distance.
Use tires of the recommended load capacity for
your vehicle. Never overload them.
WARNING!
Improperly inflated tires are dangerous and
can cause collisions.
Underinflation increases tire flexing and can
result in overheating and tire failure.
Overinflation reduces a tire's ability to cushion
shock. Objects on the road and chuckholes
can cause damage that result in tire failure.
Overinflated or underinflated tires can affect
vehicle handling and can fail suddenly,
resulting in loss of vehicle control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
Unequal tire pressures from one side of the
vehicle to the other can cause the vehicle to
drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pressure.
WARNING!

23_DPF_OM_EN_USC_t.book Page 397

SERVICING AND MAINTENANCE401
Summer tires do not contain the all season
designation or mountain/snowflake symbol on the
tire sidewall. Use Summer tires only in sets of four;
failure to do so may adversely affect the safety and
handling of your vehicle.
Snow Tires
Some areas of the country require the use of snow
tires during the Winter. Snow tires can be identified
by a mountain/snowflake symbol on the tire
sidewall. If you need snow tires, select tires
equivalent in size and type to the original
equipment tires. Use snow tires only in
sets of four; failure to do so may
adversely affect the safety and handling of your
vehicle.
Snow tires generally have lower speed ratings than
what was originally equipped with your vehicle and
should not be operated at sustained speeds over
75 mph (120 km/h). For speeds above 75 mph
(120 km/h) refer to original equipment or an authorized tire dealer for recommended safe
operating speeds, loading and cold tire inflation
pressures.
While studded tires improve performance on ice,
skid and traction capability on wet or dry surfaces
may be poorer than that of non-studded tires.
Some states prohibit studded tires; therefore, local
laws should be checked before using these tire
types.
SPARE TIRES — IF EQUIPPED
For restrictions when towing with a spare tire
designated for temporary emergency use
Ú
page 187.
Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped
Your vehicle may be equipped with a spare tire and
wheel equivalent in look and function to the
original equipment tire and wheel found on the
front or rear axle of your vehicle. This spare tire
may be used in the tire rotation for your vehicle. If your vehicle has this option, refer to an authorized
tire dealer for the recommended tire rotation
pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency
use only. You can identify if your vehicle is
equipped with a compact spare by looking at the
spare tire description on the Tire And Loading
Information Placard located on the driver’s side
door opening or on the sidewall of the tire.
Compact spare tire descriptions begin with the
letter “T” or “S” preceding the size designation.
Example: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original
equipment tire should be repaired (or replaced)
and reinstalled on your vehicle at the first
opportunity.
Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel,
since the wheel is designed specifically for the
compact spare tire. Do not install more than one
compact spare tire and wheel on the vehicle at any
given time.
WARNING!
Do not use Summer tires in snow/ice conditions.
You could lose vehicle control, resulting in
severe injury or death. Driving too fast for
conditions also creates the possibility of loss of
vehicle control.
CAUTION!
Because of the reduced ground clearance, do
not take your vehicle through an automatic car
wash with a compact or limited use temporary
spare installed. Damage to the vehicle may
result.
