Engine Oil
If the LOW OIL LEVEL message on the Driver
Information Center comes on, it means you need to
check your engine oil level right away. For more
information, see
Driver Information Center (DIC) on
page 3-44.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It's a good idea to check your engine oil level 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 ring
located near the coolant
surge tank. See
Engine
Compartment Overview on
page 5-12
for more
information on location.
Turn off the engine and give the oil a few minutes to
drain back into the oil pan. If you don't, the oil dipstick
might not show the actual level.
Pull out the dipstick and clean it with a paper towel or a
cloth, then push it back in all the way. Remove it
again, keeping the tip down.

How to Add Fluid
Here's how to add ¯uid. Refer to the Maintenance
Schedule to determine what kind of ¯uid to use. See
Part D: Recommended Fluids and Lubricants on
page 6-14.
1. Remove the ®ller plug.
2. Add ¯uid at the ®ller plug hole. Add only enough
¯uid to bring the ¯uid level up to the bottom of the
®ller plug hole.
3. Install the ®ller plug. Be sure the plug is fully
seated.
4. Tighten the plug to 20 lb ft (27Y).
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The master cylinder reservoir is ®lled with
hydraulic ¯uid.
It is not necessary to regularly check the ¯uid unless
you suspect there is a leak in the system. Adding ¯uid
won't correct a leak.
A ¯uid loss in this system could indicate a problem.
Have the system inspected and repaired.
When to Check and What to Use
The clutch master cylinder reservoir is located at the
rear of the engine compartment on the driver's side. See
Engine Compartment Overview on page 5-12for
more information on location.
Refer to the Maintenance Schedule to determine how
often you should check the ¯uid level in your master
cylinder reservoir and for the proper ¯uid. See
Part B:
Owner Checks and Services on page 6-8andPart
D: Recommended Fluids and Lubricants on page 6-14.

Starter Switch Check
{CAUTION:
When you are doing this check, the vehicle
could move suddenly. If it does, you or others
could be injured. Follow the steps below.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. See
Parking Brake on page 2-30if
necessary.
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. On automatic transmission vehicles, try to start the
engine in each gear. The starter should work only
in PARK (P) or NEUTRAL (N). If the starter works in
any other position, your vehicle needs service.
On manual transmission vehicles, put the shift lever
in NEUTRAL (N), push the clutch down halfway
and try to start the engine. The starter should work
only when the clutch is pushed down all the way
to the ¯oor. If the starter works when the clutch isn't
pushed all the way down, your vehicle needs
service.
Automatic Transmission Shift Lock
Control System Check
{CAUTION:
When you are doing this check, the vehicle
could move suddenly. If it does, you or others
could be injured. Follow the steps below.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
2. Firmly apply the parking brake. See
Parking Brake
on page 2-30if necessary.
Be ready to apply the regular brake immediately if
the vehicle begins to move.
3. With the engine off, turn the key to the ON position,
but don't start the engine. Without applying the
regular brake, try to move the shift lever out
of PARK (P) with normal effort. If the shift lever
moves out of PARK (P), your vehicle needs service.
