To make reaching the wiper blades
easy, simply turn the ignition to
the ON position and turn the
wipers on. Wait for them to reach
a vertical position and turn the
ignition to LOCK. Do not move the
wipers manually across the
windshield as this may cause
damage to the wipers.
Inspect the wiper arm pivots on a
regular basis to ensure that the
wiper arms move freely. Lubricate
the pivot points as necessary.
Replacing wiper blades
If the wiper blades do not work
properly after cleaning,
replacement of the blade assembly
or the blade element may be
necessary.
There are two different length
wiper blades on your vehicle. The
windshield wiper blades are 45 cm
(17.75 in) long and the liftgate
wiper is 34.9 cm (13 3/4 in) long.
Make sure you install the correct
size wiper blade in the correct
location.
To replace windshield wiper
blades:
1. Pull the wiper arm away from
the windshield and lock it into the
service position.
2. Turn the blade at an angle from
the wiper arm. Depress lock tab
and push wiper mounting arm
away from wiper blade assembly.
3. Attach the new wiper blade by
pulling wiper mounting arm down

your vehicle to comply with
applicable exhaust emission
requirements. For more
information on your vehicle's
emission control system, see the
Vehicle Emission Control
Information decal located on the
left side of the engine
compartment.
Follow these guidelines to ensure
proper emission system operation:
²Use only unleaded fuel.
²Avoid running out of fuel.
²Do not turn off the ignition
while your vehicle is in motion.
²Have the services performed
according to the intervals in the
Service Guide.
When servicing your vehicle, never
use a metal exhaust collector. A
metal collector may melt or deform
plastic parts.
Do not park, idle, or drive
your vehicle in dry grass
or other dry ground cover. The
emission system heats up the
engine compartment and exhaust
system, which can start a fire.
On vehicles without
original equipment floor
covering or insulation, do not let
passengers ride in your truck in
a manner that allows contact
between skin and the metal floor.

Cleaning the engine
A clean engine is more efficient
than a dirty one because a buildup
of grease and dirt acts as an
insulator and keeps the engine
warmer than normal. Follow these
guidelines to clean your engine:
²Take care when using a power
washer to clean the engine. The
high pressure fluid could
penetrate the sealed parts and
cause damage.
²In order to avoid cracking the
engine block, do not spray with
cold water.
²The alternator, ignition coil
packs, and air intake must be
covered to prevent water
damage when cleaning the
engine.
²Never wash or rinse the engine
while it is running; water in the
running engine may cause
internal damage.
Cleaning the wiper blades
If the wiper blades do not wipe
properly, clean both the windshield
and the wiper blades using
undiluted windshield washer
solution or a mild detergent. Rinse
thoroughly with clean water. Do
not use fuel, kerosene, paint
thinner, or other solvents to clean
your wiper blades; these fluids will
damage your blades.
