Engine Oil
Checking Engine Oil
It is a good idea to check the
engine oil every time you get fuel.
In order to get an accurate reading,
the oil must be warm and the
vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. SeeEngine
Compartment Overview on page 9-6
for the location of the engine oil
dipstick.
1. Turn off the engine and give the
oil several minutes to drain back
into the oil pan. If you do not
do this, the oil dipstick might not
show the actual level.
2. Pull the dipstick and clean it with
a paper towel or cloth, then push
it back in all the way. Remove
it again, keeping the tip down and
check the level.
When to Add Engine Oil
If the oil is below the MIN (minimum)
mark, add at least one quart/liter
of the recommended oil. This
section explains what kind of oil to
use. For engine oil crankcase
capacity, seeCapacities and
Specifications on page 10-2.
Notice:Do not add too much oil.
If the engine has so much oil
that the oil level gets above the
upper mark that shows the proper
operating range, the engine
could be damaged.SeeEngine Compartment Overview
on page 9-6for the location of
the engine oil ll cap.
Be sure to add enough oil to put the
level somewhere in the proper
operating range. Push the dipstick
all the way back in when you
are through.

Notice:
Using the wrong uid can
badly damage brake hydraulic
system parts. For example,
just a few drops of
mineral-based oil, such as
engine oil, in the brake
hydraulic system can damage
brake hydraulic system
parts so badly that they will
have to be replaced. Do not let
someone put in the wrong
kind of uid.
If you spill brake uid on your
vehicle’s painted surfaces, the
paint nish can be damaged.
Be careful not to spill brake
uid on your vehicle. If you do,
wash it off immediately. See
Exterior Cleaning on page 9-94.
Brake Wear
Your vehicle has disc brakes. Disc
brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time your vehicle is
moving, except when you are
pushing on the brake pedal rmly.
{CAUTION
The brake wear warning sound
means that soon the brakes will
not work well. That could lead
to an accident. When you hear
the brake wear warning sound,
have your vehicle serviced.
Notice:Continuing to drive with
worn-out brake pads could
result in costly brake repair.Some driving conditions or climates
can cause a brake squeal when
the brakes are rst applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent
brake pulsation. When tires are
rotated, inspect brake pads for wear
and evenly tighten wheel nuts in
the proper sequence to torque
specications inCapacities and
Specifications on page 10-2.
Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel
See your dealer/retailer if the brake
pedal does not return to normal
height, or if there is a rapid increase
in pedal travel. This could be a sign
that brake service might be required.
Brake Adjustment
Every time you apply the brakes,
with or without the vehicle moving,
the brakes adjust for wear.
