DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your vehicle.
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.
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!

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nut/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
ONLY use the driver’s side floor mat on the
driver’s side floor area. To check for interfer -
ence, with the vehicle properly parked with the
engine off, fully depress the accelerator, the
brake, and the clutch pedal (if present) to
check for interference. If your floor mat inter -
feres with the operation of any pedal, or is not
secure to the floor, remove the floor mat from
the vehicle and place the floor mat in your
trunk.
ONLY use the passenger’s side floor mat on
the passenger’s side floor area.
ALWAYS make sure objects cannot fall or slide
into the driver’s side floor area when the
vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
WARNING!
NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners are
secure to the vehicle carpet. Fully depress
each pedal to check for interference with the
accelerator, brake, or clutch pedals then
re-install the floor mats.
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,

IN CASE OF EMERGENCY305
4. Install the remaining lug nuts with the cone shaped end of the nut toward the wheel.
Lightly tighten all the lug nuts until the wheel
sits flush onto the hub and there is no play. The
nuts will have to be fully tightened once the
vehicle is lowered. Tightening an improperly
seated wheel under vehicle load can damage
the threads, cause vibration, and undermine
safety.
5. Lower the vehicle to the ground by turning the jack handle counterclockwise.
6. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for
increased leverage. Tighten the lug nuts in a
star pattern until each nut has been tightened
twice Ú page 377. If in doubt about the

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. 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
Ú
page 113.
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. 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.

(Continued)
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 recommended brake fluid
Ú page 383.
AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends against
using any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an
engineered product and its performance may be
impaired by supplemental additives. Therefore, do
not add any fluid additives to the transmission.
Avoid using transmission sealers as they may
adversely affect seals.
WARNING!
Use only manufacturer recommended brake
fluid Ú page 383. 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.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum-based fluid to contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
WARNING!
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.

378TECHNICAL SPECIFICATIONS
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 tightened.
FUEL REQUIREMENTS
While operating on gasoline with the required
octane number, 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 a dealer immediately. Use of
gasoline with a lower than recommended octane
number can cause engine failure and may void or
not be covered by the New Vehicle Limited
Warranty.
Poor quality gasoline can cause problems such as
hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand of
gasoline before considering service for the vehicle.
3.6L ENGINE
Do not use E-85 flex fuel or ethanol blends greater
than 15% in this engine. This engine is 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.
REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner burning gasoline referred to as
“reformulated gasoline”. Reformulated gasoline
contains oxygenates and are specifically blended
to reduce vehicle emissions and improve air
quality.
The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will
provide improved performance and durability of
engine and fuel system components.
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.
