Flowing/Rising Water
Shallow Standing Water

Although your vehicle is capable of driving
through shallow standing water, consider the
following Warnings and Cautions before doing so.

WARNING!
Do not drive on or across a road or path
where water is flowing and/or rising (as in
storm run-off). Flowing water can wear away
the road or path's surface and cause your
vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can
carry your vehicle away swiftly. Failure to
follow this warning may result in injuries that
are serious or fatal to you, your passengers,
and others around you.
WARNING!
Driving through standing water limits your
vehicle’s traction capabilities. Do not
exceed 5 mph (8 km/h) when driving
through standing water.
Driving through standing water limits your
vehicle’s braking capabilities, which
increases stopping distances. Therefore,
after driving through standing water, drive
slowly and lightly press on the brake pedal
several times to dry the brakes.
Failure to follow these warnings may result
in injuries that are serious or fatal to you,
your passengers, and others around you.
CAUTION!
Always check the depth of the standing
water before driving through it. Never drive
through standing water that is deeper than
the bottom of the tire rims mounted on the
vehicle.
Determine the condition of the road or the
path that is under water and if there are any
obstacles in the way before driving through
the standing water.
WARNING! (Continued)
Do not exceed 5 mph (8 km/h) when
driving through standing water. This will
minimize wave effects.
Driving through standing water may cause
damage to your vehicle’s drivetrain compo -
nents. Always inspect your vehicle’s fluids
(i.e., engine oil, transmission, axle, etc.) for
signs of contamination (i.e., fluid that is
milky or foamy in appearance) after driving
through standing water. Do not continue to
operate the vehicle if any fluid appears
contaminated, as this may result in further
damage. Such damage is not covered by
the New Vehicle Limited Warranty.
Getting water inside your vehicle’s engine
can cause it to lock up and stall out, and
cause serious internal damage to the
engine. Such damage is not covered by the
New Vehicle Limited Warranty.
CAUTION! (Continued)

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 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).

An 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 an
authorized dealer, the message can be reset by
referring to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel”.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 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
Maintenance Plan
Required Maintenance Intervals
Refer to the required maintenance intervals.

364SERVICING AND MAINTENANCE
(Continued)
Maintain engine coolant (antifreeze) concen-
tration at a minimum of 50% OAT coolant
(conforming to MS.90032) and distilled
water for proper corrosion protection of your
engine which contains aluminum compo -
nents.
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever
necessary, install ONLY the correct type ther -
mostat. Other designs may result in unsatis -
factory engine coolant (antifreeze)
performance, poor gas mileage, and
increased emissions.
Brake System
In order to ensure brake system performance,
all brake system components should be
inspected periodically. Refer to the
“Maintenance Plan” in this section for the
proper maintenance intervals.
Brake Master Cylinder
The fluid in the master cylinder should be
checked when performing under hood services
or immediately if the “Brake Warning Light” is
illuminated.

Be sure to clean the top of the master cylinder
area before removing the cap. If necessary, add
fluid to bring the fluid level up to the requirements
described on the brake fluid reservoir. With disc
brakes, fluid level can be expected to fall as the
brake pads wear. Brake fluid level should be
checked when pads are replaced. However, low
fluid level may be caused by a leak and a checkup
may be needed.
Use only manufacturer's recommended brake
fluid. Refer to “Fluids And Lubricants” in
“Technical Specifications” for further information.

WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your foot
resting or riding on the brake pedal can result
in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.
WARNING!

Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubricants”
in “Technical Specifications” for further infor-
mation. Using the wrong type of brake fluid
can severely damage your brake system
and/or impair its performance. The proper
type of brake fluid for your vehicle is also
identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter
or moisture, use only new brake fluid or fluid
that has been in a tightly closed container.
Keep the master cylinder reservoir cap
secured at all times. Brake fluid in a open
container absorbs moisture from the air
resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or
prolonged braking, resulting in sudden brake
failure. This could result in a collision.

20_RU_OM_EN_US_t.book Page 364

TECHNICAL SPECIFICATIONS389
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.

Wheel Mounting Surface

Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure that the socket is fully engaged on the lug nut/
bolt (do not insert it halfway).

Torque Patterns

After 25 miles (40 km) check the lug nut/bolt torque to be sure that all the lug nuts/bolts are
properly seated against the wheel.FUEL REQUIREMENTS
3.6L Engine
Do not use E-85 flex fuel or ethanol blends
greater than 15% in this engine.

These engines are designed to meet all
emissions regulations and provide
optimum fuel economy and performance
when using high quality unleaded
“Regular” gasoline having a posted octane number
of 87 as specified by the (R+M)/2 method. The use
of higher octane “Premium” gasoline is not
required, as it will not provide any benefit over
“Regular” gasoline in these engines.

While operating on gasoline with an octane
number of 87, hearing a light knocking sound from
the engine is not a cause for concern. However, if
the engine is heard making a heavy knocking
sound, see an authorized dealer immediately. Use
of gasoline with an octane number lower than 87
can cause engine failure and may void or not be
covered by the New Vehicle Limited Warranty.

WARNING!

To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully until
the vehicle has been lowered. Failure to follow
this warning may result in personal injury.
