Q:Because I have a disability, I
have to get my vehicle
modied. How can I nd out
whether this will affect my
airbag system?
A:If you have questions, call
Customer Assistance. The phone
numbers and addresses for
Customer Assistance are in Step
Two of the Customer Satisfaction
Procedure in this manual. See

diagnostic module and airbag wiring.
Restraint System
Check
Checking the Restraint
Systems
Safety Belts
Now and then, check the safety belt
reminder light, safety belts,
buckles, latch plates, retractors, and
anchorages are all working
properly.
Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from doing its job. See your
dealer/retailer to have it repaired.
Torn or frayed safety belts may not
protect you in a crash. They can
rip apart under impact forces.
If a belt is torn or frayed, get a new
one right away.
Make sure the safety belt reminder
light is working. SeeSafety Belt
Reminders on page 3-30for more
information.Keep safety belts clean and dry.
SeeCare of Safety Belts on
page 5-86.
Airbags

regularly scheduled maintenance or
replacement. Make sure the
airbag readiness light is working.
SeeAirbag Readiness Light
on page 3-31for more information.
Notice:If an airbag covering
is damaged, opened, or broken,
the airbag may not work properly.
Do not open or break the airbag
coverings. If there are any opened
or broken airbag covers, have
the airbag covering and/or airbag
module replaced. For the
location of the airbag modules,
seeWhat Makes an Airbag
Inflate? on page 1-50. See your
dealer/retailer for service.

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 — See
Safety Belts: They Are for Everyone
on page 1-12.
{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.
Drunk Driving
{CAUTION
Drinking and then driving is very
dangerous. Your reexes,
perceptions, attentiveness, and
judgment can be affected by even
a small amount of alcohol. You
can have a serious — or even
fatal — collision if you drive after
drinking. Do not drink and drive or
ride with a driver who has been
drinking. Ride home in a cab; or if
you are with a group, designate a
driver who will not drink.
Death and injury associated with
drinking and driving is a global
tragedy.
Alcohol affects four things that
anyone needs to drive a vehicle:
judgment, muscular coordination,
vision, and attentiveness.
4-2 Driving Your Vehicle

Parking on Hills
{CAUTION
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a at surface.
If parking the rig on a hill:
1. Press the brake pedal, but do
not shift into P (Park) yet.
Turn the wheels into the curb if
facing downhill or into traffic
if facing uphill.
2. Have someone place chocks
under the trailer wheels.3. When the wheel chocks are in
place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then
apply the parking brake and shift
the transmission into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake
pedal while you:
start the engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is
clear of the chocks.
4. Stop and have someone pick up
and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer.
SeeScheduled Maintenance on
page 6-3for more information.
Things that are especially important
in trailer operation are automatic
transmission uid, engine oil,
axle lubricant, belts, cooling system
and brake system. It is a good
idea to inspect these before and
during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.

How to Reset the Engine Oil
Life System
The Engine Oil Life System
calculates when to change the
engine oil and lter based on vehicle
use. Whenever the oil is changed,
reset the system so it can calculate
when the next oil change is required.
If a situation occurs where you
change the oil prior to a CHANGE
ENGINE OIL SOON message being
turned on, reset the system.
To reset the Engine Oil Life System:
1. Turn the ignition to ON/RUN,
with the engine off.
2. Press the vehicle information
button until OIL LIFE
REMAINING displays.
3. Press and hold the set/reset
button until 100% is displayed.
You will hear three chimes
and the CHANGE ENGINE OIL
SOON message will go off.
4. Turn the key to LOCK/OFF.If the CHANGE ENGINE OIL SOON
message comes back on when
you start the vehicle, the engine oil
life system has not reset. Repeat
the procedure.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer’s warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your own
oil, be sure to drain all the oil from the
lter before disposal. Never dispose
of oil by putting it in the trash, pouring
it on the ground, into sewers, or into
streams or bodies of water. Recycle
it by taking it to a place that collects
used oil.
Engine Air Cleaner/Filter
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/lter at the
MaintenanceIIintervals and replace
it at the rst oil change after each
50,000 mile (80 000 km) interval.
SeeScheduled Maintenance
on page 6-3for more information.
If you are driving in dusty/dirty
conditions, inspect the lter at each
engine oil change.
SeeEngine Compartment Overview
on page 5-10for the location of
the engine air cleaner/lter.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/lter,
remove the lter from the vehicle and
lightly shake the lter (away from
vehicle) to release loose dust and
dirt. If the lter remains caked with
dirt, a new lter is required.
