WARNING
∙ Do not use starting fluid, such asether, in the air intake system. Use of
such fluid could cause engine dam-
age and/or personal injury.
∙ Do not add gasoline, alcohol or kero- sene to diesel fuel.
CAUTION
∙ Read all starting instructions carefullyprior to starting your vehicle.
∙ When starting the engine in ex- tremely cold temperatures, it is rec-
ommended to allow the engine to idle
for several minutes before driving the
vehicle.
∙ The use of the factory engine block heater (if so equipped) will assist in
starting the engine in extreme cold
ambient temperatures. For additional
information, refer to the “Starting and
driving” section of the Titan Owner’s
Manual. Engine warming
This message may display during cold
starting conditions. It is a reminder that
during cold starting conditions the engine
may not crank immediately af ter pushing
the ignition switch, and could take up to
approximately 4 seconds to crank. The
brake pedal must be depressed during this
wait period.
1. Verif y the shif t lever is in the P (Park) or N (Neutral) position. P (Park) is recom-
mended. The shif t lever cannot be moved out
of P (Park) and into any of the other
gear positions if the ignition switch
is in the OFF position.
The starter is designed not to oper-
ate if the shif t lever is in any of the
driving positions.
2. There are two ways to start your diesel engine:
∙ Push the ignition switch to the ON position, and wait up to 4 seconds for
the glow plug to warm up. Depress
the brake pedal and push the ignition
switch to start the engine.

STARTING THE DIESEL ENGINE
3-2Starting and Stopping the Engine

CAUTION
If the engine does not start, place the
ignition switch in the OFF position and
wait 10 seconds before cranking again,
otherwise the starter could be
damaged.3. Allow the engine to idle for at least 30 seconds af ter starting. Do not race
the engine while warming it up. Drive at
a moderate speed for a short distance
first, especially in cold weather.
In cold weather, keep the engine run-
ning for a minimum of 2–3 minutes
before shutting it off. Starting and
stopping the engine over a short pe-
riod of time may make the vehicle
more difficult to start.
SWITCHING ENGINE OFF
Push the ignition switch to the OFF posi-
tion.
To prolong the engine life (especially af ter
extended high speed, high ambient tem-
perature, or during heavy load operation,
such as trailering), it is recommended that
a hot engine be idled for 3–5 minutes be-
fore shutting down. This allows the turbo-
charged engine to cool down.
ENGINE BREAK-IN
RECOMMENDATIONS
∙ Warm up the engine before operating it under load.
∙ Do not operate the engine at idle for extended periods.
∙ Prevent engine lugging by selecting the appropriate transmission gear.
∙ Monitor the vehicle oil pressure and temperature gauges.
∙ Check fluid levels frequently (oil and coolant).
∙ Vary the throttle position at highway speeds when carrying weight or tow-
ing.
NOTE:
Extended light or no load operation will
extend the time before the engine
reaches its full efficiency. If the engine is
operated in this manner, reduced fuel
economy and power may be observed.
The aforementioned procedure should be
observed for the first 6,000 miles. The en-
gine run-in is improved by operating the
vehicle under load.
REMOTE ENGINE START (if so
equipped)
CAUTION
Laws in some jurisdictions prohibit use
of Remote Engine Start.
Vehicles started with the Remote Engine
Start require the ignition switch to be
placed in the ON position before the shif t
lever can be moved from the P (Park) posi-
tion. To place the ignition switch in the ON
position, follow these steps: 1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Push the ignition switch once to the ON position.
For additional information, refer to “NISSAN
Intelligent Key®” in the “Pre-driving checks
and adjustments” section of the Titan
Owner’s Manual.
