change the
way the fuel injection system operates. Before adding
electrical equipment, check with your dealer.
If you don’t, your
engine might not perform properly.
If you ever have to have your vehicle towed, see the part of this
manual that tells how to do it without damaging your vehicle.

Driving Through Deep Standing Water
NOTICE:
If you drive too quickly through deep puddles or standing water,
water can come in through your engine’s air intake and badly
damage your engine. Never drive through water that is slightly \
lower than the underbody of your vehicle.
If you can’t avoid
deep puddles or standing water, drive through them very
slowly.
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 PARK (P) or
NEUTRAL
(N). Your engine won’t start in any other position - that’s

the RUN position, you must fully apply your regular brakes before you can
shift from PARK (P).
If you cannot shift out of PARK (P), ease pressure on the shift lever and
push the
shift lever all the way into PARK (P) as you continue pressing the
brake pedal.
Then move the shift lever into the gear you want. If you still
cannot shift the shift lever out of
PARK (P), see ”Shifting Out of PARK (P)”
later in this section.

Shifting to REVERSE (R) while your vehicle is moving forward
could damage your transmission. Shift to REVERSE
(R) only
after your vehicle is stopped.

without damaging your transmission, see
“If You‘re Stuck: In Sand,
Mud, Ice or Snow”
in the Index.

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. Always check to be sure
your parking brake is fully released before you drive.

Propshaft Brake Burnish Procedure
If you have a 3500 HD model, it is recommended that the propshaft mounted
parking brake be burnished
as part of the new vehicle break in. The parking
brake will work best after
it has been burnished following these instructions.
Make
10 (ten) stops, using the parking brake foot pedal, from 20 mph (32
km/h) about
2 1/2 miles (4 km) apart. In between stops, drive the vehicle at
20 mph (32 km/h).
Torque Lock
When parking, the weight of the vehicle may put too much force on the
parking pawl
in the transmission. It may be difficult to pull the selector
lever out of
PARK (P). This is called ”torque lock.” To find out how to
avoid torque lock, see “Torque Lock” later in this section.

Leaving Your Vehicle With the Engine Running
(Automatic Transmission Models
Only)
A CAUTION:
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.
If you have to leave your vehicle with the engine running, be sure your
vehicle is in PARK (P) and your parking brake is firmly set before you leave
it. After you’ve moved the shift lever into the PARK (P) position, hold the
regular brake pedal down. Then. see
if you can move the shift lever away
from PARK (P) without first pulling
it toward you.
If
you can, it means that the shift lever wasn’t fully locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you don’t shift your transmission into PARK
(P) properly, the weight of the vehicle may put too much force on the
parking pawl in the transmission.
You may find it difficult to pull the shift
lever out of PARK (P). This is called “torque lock.” To prevent torque lock,
set the parking brake and then shift into PARK (P) properly before you
leave the driver’s seat.
To find out how, see “Shifting Into PARK (P)” in the
Index.
When you are ready to drive, move the shift lever out
of PARK (P) before
you release the parking brake.
If “torque lock” does occur, you may need to have another vehicle push
yours
a little uphill to take some of the pressure from the transmission, so
you can pull the shift lever out of PARK (P).

dangerous exhaust into your vehicle (see the earlier Caution
under “Engine Exhaust”).
Also, idling in a closed-in place can let deadly carbon monoxide
~ (CO) into your vehicle even if the fan switch is at the highest
setting. One place this can happen is a garage. Exhaust
- with
CO - can come in easily. NEVER park in a garage with the
engine running.
Another closed-in place can be
a blizzard. (See “Blizzard” in the
Index.)

It can be dangerous to get out of your vehicle if the shift lever is
not fully in PARK
(P) with the parking brake firmly set. Your
vehicle can roll. Don’t leave your vehicle when the engine
is
running unless you have to. If you’ve left the engine running, the
vehicle can move suddenly. You or others could be injured.
To be
sure your vehicle won’t move, even when you’re on fairly level
ground, always set your parking brake and move the shift lever
to PARK
(P).
If you have four-wheel drive 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). Always
set your parking brake. Follow the proper steps to be sure your vehicle
won’t move. See “Shifting Into PARK
(P)“ in the Index.
If you’re pulling a trailer. see ”Towing a Trailer“ in the Index.
