overheating Ram 4500 Chassis Cab 2017 User Guide

CAUTION!(Continued)
in long enough without engine operation, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Next, shift back and forth between DRIVE and
REVERSE (with automatic transmission) or 2nd gear and
REVERSE (with manual transmission) while gently press-
ing the accelerator. Use the least amount of accelerator
pedal pressure that will maintain the rocking motion,
without spinning the wheels or racing the engine.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
least one minute after every five rocking-motion
(Continued)
CAUTION!(Continued)
cycles. This will minimize overheating and reduce the
risk of clutch or transmission failure during prolonged
efforts to free a stuck vehicle.
NOTE: Push the ESC Off switch, to place the Electronic
Stability Control (ESC) system in Partial Offmode, before
rocking the vehicle. Refer to “Electronic Brake Control” in
“Starting And Operating” for further information. Once
the vehicle has been freed, push the ESC Offswitch again
to restore ESC Onmode.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle’s wheels
faster than 30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when you are
stuck and do not let anyone near a spinning wheel, no
matter what the speed.

WHAT TO DO IN EMERGENCIES 439

CAUTION!
•When “rocking” a stuck vehicle by shifting between
DRIVE/2nd gear and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis-
sion shifting occurring).
EMERGENCY TOW HOOKS — IF EQUIPPED
Your vehicle may be equipped with emergency tow hooks.
NOTE: For off-road recovery, it is recommended to use
both of the front tow hooks to minimize the risk of damage
to the vehicle.
WARNING!
• Do not use a chain for freeing a stuck vehicle. Chains
may break, causing serious injury or death.
• Stand clear of vehicles when pulling with tow hooks.
Tow straps may become disengaged, causing serious
injury.
CAUTION!
Tow hooks are for emergency use only to rescue a
vehicle stranded off-road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle.
440 WHAT TO DO IN EMERGENCIES

In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
•Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.
Cooling System
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
(Continued)
WARNING! (Continued)
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator is hot.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable). If the engine coolant (antifreeze) is dirty or rusty in
appearance, the system should be drained, flushed and
refilled with fresh coolant. Check the front of the A/C
condenser (if equipped) or radiator for any accumulation
of bugs, leaves, etc. If dirty, clean by gently spraying water
from a garden hose vertically down the face of the A/C
condenser (if equipped) or the back of the radiator core.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts and tightness of the connection at the
coolant recovery bottle and radiator. Inspect the entire
system for leaks.
With the engine at normal operating temperature (but not
running), check the cooling system pressure cap for proper
vacuum sealing by draining a small amount of engine
