If you’re not in an idling vehicle and the engine overheats, you
wouldn’t be there to see the coolant temperature gage. This
could damage your vehicle. Don’t let your engine run when
you’re not in your vehicle.
Cold Weather Starting (Diesel Engine)
The following tips will help you get good starting in cold weather.
Use
SAE 1OW-30 oil when the outside temperature drops below freezing.
When the outside temperature drops below
0” F (- 18 O C), use your engine
coolant heater.
If you park your vehicle
in a garage, you shouldn’t need to use the coolant
heater until the garage temperature goes below
0°F (-1 8OC), no matter how
cold it is outside.
To use the engine coolant heater, first turn off the engine. Then open the
hood, unwrap the electrical cord and plug
it in. It uses normal house voltage
(110 volts), but:
I NOTICE:
After you’ve used the coolant heater, be sure to store the cord in
the manner it was, to help keep it away from moving engine
parts.
If you don’t, it could be torn and damaged.

lower fuel economy) than SECOND GEAR (2).
You can use it on very
steep hills, or
in deep snow or mud. If the selector lever is put in FIRST
GEAR
(1 j while the vehicle is moving forward, the transmission won’t
shift
into FIRST GEAR (1) until the vehicle is going slowly enough.
NOTICE:
If your rear wheels can’t rotate, don’t try to drive. This might
happen if you were stuck in very deep sand or mud
or were up
against a solid object. You could damage your transmission.
Also, if you stop when going uphill, don’t hold your vehicle there
with only the accelerator pedal. This could overheat and damage\

the transmission. Use your brakes or shift into
PARK (P) to hold
your vehicle in position on a hill.
Five Speed Manual Transmission
If you have a five
speed manual
transmission, this is
your shift pattern.
Here’s how to operate
your transmission:
FIRST GEAR (1) - Press the clutch pedal and shift into FIRST
GEAR (1). Then, slowly let up on the clutch pedal as you press the
accelerator pedal.
You can shift into FIRST GEAR (1) when you’re going less than 20
mph (32 km/h). If you’ve come to a complete stop and it’% hard to shift
into FIRST GEAR (I), put the shift lever in NEUTRAL (Nj and let up
on the clutch. Press the clutch pedal back down. Then shift into FIRST
GEAR
(1).
SECOND GEAR (2) - Press the clutch pedal as you let up on the
accelerator pedal and shift into SECOND GEAR (2). Then, slowly let
up on the clutch pedal as you press the accelerator pedal.

To set the parking brake:
Hold the regular brake
pedal down with your
right foot. Push down
the parking brake
pedal with your left
foot.
If the ignition is on, the brake system warning light will come on.
To release the parking brake:
Hold the regular brake
pedal down. Pull the
lever, located just
above the parking
brake pedal, marked
BRAKE RELEASE,
to release the parking
brake.
If the ignition is on when the parking brake is released, the brake system
warning light will
go off.
I NOTICE:
Driving with the parking brake on can cause your rear brakes to
overheat. You may have to replace them, and you could also
damage other parts
of your vehicle.
If you are towing a trailer and are parking on any hill: See “Towing a
Trailer” in the Index. That section shows what to do first to keep the trailer
from moving.

4. Move the ignition key to LOCK.
-not in NEUTRAL (N)
5. Remove the key and take it with you. If you can walk away from your
vehicle with the ignition key
in your hand, your vehicle is in PARK (P).
Shifting Out of PARK (P)
Your vehicle has a brake-transmission shift interlock system. You have to
fully apply your regular brakes before you can shift from PARK (P). See
“Automatic Transmission”
in the Index.
If
you cannot shift out of PARK (P), ease pressure on the shift lever and
push the shift lever all the way up into PARK
(P) as you maintain brake
application. Then, move the shift lever into the gear you want.
If
you ever hold the brake pedal down but still can’t shift out of PARK (P),
try this:
1. Turn the key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear you want.
5. Have the brake-transmission shift interlock system fixed as soon as
you can.
Leaving Your Vehicle With the Engine Running
(Automatic Transmission
Models Only)
It can be dangerous to leave your vehicle with the engine
running. Your vehicle could move suddenly if the shift lever
is
not fully in PARK (P) with the parking brake firmly set. If you
have four-wheel drive with
a manual transfer case shift lever
and your transfer case
is in NEUTRAL (N), your vehicle will be
free to roll, even if your shift lever
is in PARK (P). So be sure the
transfer case is in
a drive gear - not in NEUTRAL (N). And, if
you leave the vehicle with the engine running, it could overheat
and even catch
fire. You or others could be injured. Don’t leave
your vehicle with the engine running unless you have to.

Downloaded from www.Manualslib.com manuals search engine For a single wiping cycle, turn the band to MIST. Hold it there until the
wipers start, then let go. The wipers will stop after one cycle. If you want
more cycles, hold the band
on MIST longer.
You can set the wiper speed for a long or short delay between wipes. This
can be very useful in light rain or snow. Turn the band to choose the delay
time. The closer
to LOW, the shorter the delay.
For steady wiping at low speed,
turn the band to the LOW position. For high
speed wiping, turn the band further, to
HIGH. To stop the wipers, move the
band to the off symbol.
Remember that damaged wiper blades may prevent
you from seeing well
enough to drive safely.
To avoid damage, be sure to clear ice and snow from
the wiper blades before using them.
If they are frozen to the windshield,
carefully loosen or thaw them.
If your blades do become damaged, get new
blades
or blade inserts.
Heavy snow or ice can overload your wipers. The windshield wiper motor is
protected from overload by a circuit breaker and
a fuse. If the motor
overheats due to heavy snow, etc.,
the wiper will stop until the motor cools.
Although the circuit is protected from electrical overload, overload due
to
heavy snow, etc. may cause wiper linkage damage. Always clear ice and
heavy snow from the windshield before using your windshield wipers.
Windshield Washer
At the top of the lever
there’s a paddle with
the word PUSH on it.
To spray washer fluid
on the windshield,
push the paddle.
Washer fluid will spray as long as
you push the paddle. When you let go of
the paddle, the wipers will continue to wipe for a few seconds and then
either stop or return to the preset speed.
Driving without washer fluid can be dangerous.
A bad mud splash can block
your vision. You
could hit another vehicle or go off the road. Check your
washer fluid level often.

GLOW
PLUGS
If you have a diesel engine, it has a special starting system. An orange
instrument panel Glow Plugs light shows that the system is functioning
properly and tells you when the engine is ready to be started. For more
details, see “Starting Your Diesel Engine”
in the Index.
Low Coolant Warning Light
If you have a diesel engine, you have a low coolant light. As a check to
show you it’s working, this orange light comes on for a few seconds after
the ignition
is turned on. If this light comes on anytime the engine is
running,
your system is low on coolant and the engine may overheat. See
“Engine
Coolant” in the Index and have your vehicle serviced as soon as
you can.

For example, the gage may have indicated the tank was half
full, but it
actually took a little more or less than half the tank’s capacity to fill the
tank.
The gage moves a little when you turn a corner or speed up.
0 The gage doesn’t go back to empty when you turn off the ignition.
None of these indicate a problem with the fuel gage.
For information on how to fill your fuel tank, see “Fuel
- Filling Your
Tank”
in the Index.
For your
fuel tank capacity, see “Fuel -Tank Capacity” in the Index.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. Most of the time, the gage
pointer will show your coolant temperature at 210°F (99”C), or less. But,
if
you are pulling a heavy load or driving up hills, your coolant temperature
may rise and fall near
the red 260°F (1 28°C) mark. This is normal. If the
gage pointer moves
to the red 260°F (1 28°C) mark, your engine is too hot!
It means that your engine coolant has overheated. You should pull off the
road, stop
your vehicle, and turn off the engine as soon as possible.
Hot Coolant Can Burn You Badly!
In “Problems on the Road,” this manual shows what to do. See “Engine
Overheating”
in the Index.
