Your Driving, the Road, and
the Vehicle
Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here are some
driving tips to get the best fuel economy possible.
Avoid fast starts and accelerate smoothly.
Brake gradually and avoid abrupt stops.
Avoid idling the engine for long periods of time.
When road and weather conditions are appropriate,
use cruise control, if equipped.
Always follow posted speed limits or drive more
slowly when conditions require.
Keep vehicle tires properly inated.
Combine several trips into a single trip.
Replace the vehicle’s tires with the same TPC Spec
number molded into the tire’s sidewall near the size.
Follow recommended scheduled maintenance.
Defensive Driving
Defensive driving means “always expect the
unexpected.” The rst step in driving defensively is to
wear your safety belt — SeeSafety Belts: They Are for
Everyone on page 1-14.
{CAUTION:
Assume that other road users (pedestrians,
bicyclists, and other drivers) are going to be
careless and make mistakes. Anticipate what they
might do and be ready. In addition:
Allow enough following distance between you
and the driver in front of you.
Focus on the task of driving.
Driver distraction can cause collisions resulting in
injury or possible death. These simple defensive
driving techniques could save your life.

Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
Windshield Washer Fluid:Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All levels checked?
Lamps:Do they all work and are lenses clean?
Tires:Are treads good? Are tires inated to
recommended pressure?
Weather and Maps:Safe to travel? Have
up-to-date maps?
Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, nd a
safe place to park your vehicle and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan the road ahead
and to the sides.
Check the rearview mirror and vehicle instruments
often.

To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine
off and close the window most of the way to save heat.
Repeat this until help arrives but only when you feel really
uncomfortable from the cold. Moving about to keep warm
also helps.
If it takes some time for help to arrive, now and then
when you run the engine, push the accelerator
pedal slightly so the engine runs faster than the idle
speed. This keeps the battery charged to restart
the vehicle and to signal for help with the headlamps.
Do this as little as possible to save fuel.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
Slowly and cautiously spin the wheels to free the
vehicle when stuck in sand, mud, ice, or snow.
SeeRocking Your Vehicle to Get It Out on page 4-20.If the vehicle has a traction system, it can often help to
free a stuck vehicle. Refer to the vehicle’s traction
system in the Index. If stuck too severely for the traction
system to free the vehicle, turn the traction system off
and use the rocking method.
{CAUTION:
If you let your vehicle’s tires spin at high speed,
they can explode, and you or others could be
injured. The vehicle can overheat, causing an
engine compartment re or other damage. Spin the
wheels as little as possible and avoid going above
35 mph (55 km/h) as shown on the speedometer.
For information about using tire chains on the vehicle,
seeTire Chains on page 5-84.

passengers, and cargo should never exceed the
vehicle’s maximum vehicle capacity weight.
Certication Label
A vehicle specic Certication label is attached to
the driver side center pillar.
The label shows the gross weight capacity of your
vehicle, called the Gross Vehicle Weight Rating
(GVWR). The GVWR includes the weight of the
vehicle, all occupants, fuel, cargo, and tongue
weight if pulling a trailer.

When dinghy towing the vehicle, the vehicle should be
run at the beginning of each day and at each RV fuel stop
for about ve minutes. This will ensure proper lubrication
of transmission components.
For vehicles that can be dinghy towed with all four wheels
on the ground:
1. Position the vehicle to tow and then secure it to the
towing vehicle.
2. Shift the transmission to P (Park) and turn the
ignition to LOCK/OFF.3. Set the parking brake.
4. To prevent the battery from draining while the vehicle
is being towed, remove the following fuse from the
instrument panel fuse block: (IGN SENSOR). See
Instrument Panel Fuse Block on page 5-110for more
information.
5. Turn the ignition to ACC/ACCESSORY.
6. Shift the transmission to N (Neutral).
7. Release the parking brake.
Remember to reinstall the IGN SENSOR fuse once the
destination has been reached.
Notice:If 65 mph (105 km/h) is exceeded while
towing the vehicle, it could be damaged. Never
exceed 65 mph (105 km/h) while towing the vehicle.

Towing a Trailer
{CAUTION:
The driver can lose control when pulling a trailer if
the correct equipment is not used or the vehicle is
not driven properly. For example, if the trailer is
too heavy, the brakes may not work well — or
even at all. The driver and passengers could be
seriously injured. The vehicle may also be
damaged; the resulting repairs would not be
covered by the vehicle warranty. Pull a trailer only
if all the steps in this section have been followed.
Ask your dealer/retailer for advice and information
about towing a trailer with the vehicle.
Notice:Pulling a trailer improperly can damage the
vehicle and result in costly repairs not covered
by the vehicle warranty. To pull a trailer correctly,
follow the advice in this section and see your
dealer/retailer for important information about
towing a trailer with the vehicle.The vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. To identify the trailering
capacity of the vehicle, read the information in “Weight of
the Trailer” that appears later in this section. Trailering is
different than just driving the vehicle by itself. Trailering
means changes in handling, acceleration, braking,
durability and fuel economy. Successful, safe trailering
takes correct equipment, and it has to be used properly.
The following information has many time-tested,
important trailering tips and safety rules. Many of
these are important for the safety of the driver and the
passengers. So please read this section carefully before
pulling a trailer.
Load-pulling components such as the engine,
transmission, axles, wheel assemblies and tires are
forced to work harder against the drag of the added
weight. The engine is required to operate at relatively
higher speeds and under greater loads, generating extra
heat. The trailer also adds considerably to wind
resistance, increasing the pulling requirements.

If doing some of your own service work, use the proper
service manual. It tells you much more about how to
service the vehicle than this manual can. To order
the proper service manual, seeService Publications
Ordering Information on page 7-15.
This vehicle has an airbag system. Before attempting to
do your own service work, seeServicing Your
Airbag-Equipped Vehicle on page 1-74.
Keep a record with all parts receipts and list the mileage
and the date of any service work performed. See
Maintenance Record on page 6-17.
Adding Equipment to the Outside of
the Vehicle
Things added to the outside of the vehicle can affect the
airow around it. This can cause wind noise and can
affect fuel economy and windshield washer performance.
Check with your dealer/retailer before adding equipment
to the outside of the vehicle.
Fuel
Use of the recommended fuel is an important part of the
proper maintenance of this vehicle. To help keep the
engine clean and maintain optimum vehicle performance,
we recommend the use of gasoline advertised as TOP
TIER Detergent Gasoline.
The 8th digit of the Vehicle Identication Number (VIN)
shows the code letter or number that identies the
vehicle’s engine. The VIN is at the top left of the
instrument panel. SeeVehicle Identification Number
(VIN) on page 5-108.
If the vehicle has the 3.5L V6 engine (VIN Code K),
you can use either unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85). SeeFuel E85
(85% Ethanol) on page 5-8. In all other engines, use
only the unleaded gasoline described underGasoline
Octane on page 5-7.
