NOTICE:
If your key seems stuck in “LOCK” and you can’t turn it, be
sure it is all the way in.
If it is, then turn the steering wheel left
and right while
you turn the key hard. But turn the key only
with your hand. Using a tool to force
it could break the key or
the ignition switch.
If none of this works, then your vehicle needs
service.
Key Release Lever
The ignition key
cannot be removed
from the ignition of
.. manual transmission
vehicles unless the
To Remove the Key
On manual transmission vehicles, turn the key to the LOCK position while
pressing the key release lever down (see the caution earlier
in this section
about the key release lever). Keeping your finger
on the lever, pull the key
straight out.
On automatic transmission vehicles, turn the
key to LOCK and pull it
straight out.
Starting Your Gasoline Engine
If you have a diesel engine, see “Starting Your Diesel Engine” in the Index.
Engines start differently. The
8th digit of your Vehicle Identification
Number (VIN) shows the code letter or number for your engine.
You will
find the VIN at the top left of your instrument panel. (See “Vehicle
Identification Number” in
the Index.) Follow the proper steps to start the
engine.

Driving In Snow (Diesel Engines)
When driving in a heavy snowstorm or in swirling snow with a diesel
engine, snow can get into
the air intake system. If you keep driving in these
conditions the air cleaner may get plugged, causing black smoke and loss of
power. In an emergency, if the air cleaner gets plugged with snow, you can
remove the air cleaner.
Then, drive to a place of safety as soon as possible
and put the air cleaner back
on.
Starting Your Diesel Engine
Your diesel engine starts differently than a gasoline engine.
1. Automatic Transmission:
Move your shift lever to “P’ (Park) or “N” (Neutral). Your engine
won’t start in any other position
- that’s a safety feature. To restart
when you’re already moving, use
“N” (Neutral) only.
NOTICE:
Don’t try to shift to 4‘P’’ (Park) if your vehicle is moving. If you
do, you could damage the transmission. Shift to
“P” (Park) only
when your vehicle is stopped.
2. Manual Transmission:
Move your shift lever to neutral and hold the clutch pedal to the floor
while starting
the engine. Your vehicle won’t start if the clutch pedal is
not all the way down - that’s a safety feature.
Turn your ignition
key to RUN. Don’t turn it to START.
With the ignition in RUN, the “GLOW PLUGS” light will come on. If
the engine is already warm, this light may
not come on. That’s normal.
During starting, your “GLOW
PLUGS” light may go on and off a few
times. This
is normal. This means that part of your engine is being
warmed up for better starting. When the light goes off, your engine is
ready to start.
Do not start the engine with this light on.
NOTICE:
If the “GLOW PLUGS” light stays on, it means that your
vehicle could have one
of several problems, so you should have it
serviced right away.

If Your Diesel Engine Won’t Start
If you’ve run out of fuel, look at “Running Out of Fuel” (see “Diesel Fuel
Requirements and Fuel System” in the Index).
If you’re not out of fuel, and your engine won’t start, do this:
Turn your ignition key to RUN. Make sure that the “GLOW PLUGS” light
is out. Then turn the ignition key to
START.
If the light doesn’t go off, wait a few seconds, then try starting your engine
again. And, see your dealer as soon as you can for a starting system check.
If the light comes on and then goes off and you know your batteries are
charged, but your engine still won’t start, your vehicle needs service.
If the light does not come
on when the engine is cold, your vehicle needs
service.
If your batteries don’t have enough charge to start your engine, see
“Battery” in the Index.
Be sure you have the right oil for your engine, and that you’ve changed the
oil at the proper times. If you use the wrong oil, your engine may be harder
to start.
If the engine starts, runs a short time, then stops, your vehicle needs service.

Waiting to do repairs can be costly - and even dangerous. So please get to
know your warning lights and gages. They’re a big help.
Brake System Warning Light
The red brake system
warning light is
located at the bottom
right corner of the
instrument cluster
Your vehicle’s hydraulic brake system is divided into two parts. If one part
isn’t working, the other part can still work and stop you. For
good braking,
though, you need both parts working well.
If the warning light comes on, there could be a brake problem. Have your
brake system inspected right away.
This light should come on as you start the vehicle. If it doesn’t come on
then, have it fixed
so it will be ready to warn you if there’s a problem.
If the light comes on while you are driving, pull off the road and stop
carefully. You may notice that the pedal is harder to push. Or, the pedal may
go closer to the floor. It may take longer to stop. If the light is still on, have
the vehicle towed for service. (See “Towing Your Vehicle” in the Index.)
The brake system warning light will also come on when you set your
parking brake, and it will stay on if your parking brake doesn’t release fully.
If it stays on after your parking brake is fully released, it means you have a
brake problem.

Anti-Lock Brake System Warning Light
The orange anti-lock
brake system warning light is located near
the top right corner
of
the instrument cluster
mi
With anti-lock, this light will go on when you start your engine and may
stay
on for several seconds. That’s normal. If the light doesn’t come on,
have it fixed
so it will be ready to warn you if there is a problem.
If the light stays on, or comes on when you’re driving, your vehicle needs
service.
If the regular brake system warning light isn’t on, you still have
brakes, but you don’t have anti-lock brakes. If the regular brake system
warning light is also
on, you don’t have anti-lock brakes and there’s a
problem with your regular brakes. See “Brake System Warning Light’’
earlier in this part.
Water in Fuel Light
The red Water in Fuel
light, if
you have one,
is located near the
middle right edge of
the instrument cluster,
just below the turn
signal and lane change
indicator.
This light will come on
to warn you if there is water in the diesel fuel
system.
For more information on how this light works, see “Diesel Fuel
Requirements and Fuel System”
in the Index.

Service Throttle Soon Light
The orange Service
Throttle Soon light,
if
you have one, is
located near the
middle left edge
of the
instrument cluster
On diesel engines, a computer monitors the operation of the electronic
accelerator. This light should come
on when the ignition is on but the engine
is not running, as a check to show you its working. If it does not come on at
all, have it fixed right away.
If the light stays on after the engine starts or
comes on while you are driving, the computer is indicating that you have a
problem. You should take your vehicle in for service soon.
Glow Plugs Light
The orange Glow
Plugs light, if you
have
one, is located
near the upper right
corner
of the
instrument cluster.
If you have a diesel engine, it has a special starting system. An instrument
panel Glow Plugs light tells you when
the engine is ready to be started. For
more details, see “Starting Your Diesel Engine” in the Index.
