Engine preheater
Applies to vehicles: with engine p reheate r
Use of the engine pre heater is recommended
when the ambient temperature is below
-5 °F
(-20 °C) .
Fig. 100 In t he l eft fron t bump er: en gine preheater
co nn ect ion socket
The engine preheater slowly w arms the en­
gine coolant using a heating element when
the vehicle is parked. The included cable
1>
must be connected to a 120 Volt Ground Fault
Circuit (GFI) protected outlet that is protected
from water (in your garage, for instance).
When the coolant is preheated, the engine
reaches its operating temperature more quick­
ly and will use less fuel and produce fewer
polluting emissions during the warm-up
phase.
Preheating the engine can take up to 3 hours
depending on the temperature outside.
Connecting the engine preheater
- Only use the cable provided.
-All cables and connectors that are used
must not be damaged

-Connect the connecting cable to the power
cord.
- Attach the extensions cord to the connector
cable. Always use a 12 gauge or heavier
heavy -duty extension cord that can be prop ­
erly grounded to a three-prong Ground Fault
Circuit (GFI) wall outlet and is not longer
than 100
ft (30 meters).
- Always plug the preheate r into an 120 Volt
Ground Fault Circuit (GFI) wall outlet that is
properly protected against rain and other
moisture. Never plug the preheater into a
normal outlet regardless of whether it is
grounded or not .
- Always disconnect the connecting cable and
close the cover

the engine.
_&. WARNING
-
Using incorrect or damaged outlet and
power cords, using electrical accessories
incorrectly or ignoring safety precautions
can lead to short circuits, accidents, inju­ ries and life-threatening electric shocks.
- Always plug the preheater into a
120 Volt Ground Fault Circuit (GFI) wall
outlet that is properly protected against
rain and other moisture.
- Always check the fuse protection of the
120 Volt power source before using the
connecting cable .
- Always use a 12 gauge or heavier heavy­
duty extension cord that can be properly
grounded to a three-prong GFI outlet .
The extension cord must not be longer

Glow plug system*
Diesel engines are e quipped w ith a glow pl ug
system whose prehe ating time is co ntrolled
by the coo la nt an d ou tside temperature . Sta rt
the engine
immediately after the g low plug

II switches off.
T he glow plug indica to r ligh t will only illumi­
nate fo r approximate ly 1 second w hen t he en ­
gine is warm or the outside temperature is
higher than
46 °F (8 °(). That means yo u can
start the eng ine
immedia tely .
To start the diesel eng ine after the fuel
tank has been run dry
If the fuel tank was r un comp lete ly dry, the
starting process after refue ling with diesel
fuel can take longer than usua l - up to one mi­
nute . This is because the fue l system first has
to be vented of a ir wh ile s tarting .
