Charge warning light
If the light comes on while the engine is
running, it may indicate the charging system
is not functioning properly. Turn the engine
off and check the alternator belt. If the belt is
loose, broken, missing or if the light remains
on, have your vehicle serviced immediately. It
is recommended you visit an INFINITI re-
tailer for this service.
CAUTION

belt is loose, broken or missing.
Distance Control Assist (DCA)
system warning light (orange; if so
equipped)
This light comes on if there is a malfunction
in the Distance Control Assist (DCA) system.
If the warning light illuminates, park the
vehicle in a safe place. Turn the engine off,
restart the engine, resume driving and turn
on the DCA system again.
If it is not possible to turn on the system or
the warning light stays on, it may indicate
that the system is malfunctioning. Although the vehicle is still driveable under normal
conditions, have the vehicle checked. It is
recommended you visit an INFINITI retailer
for this service.
See “Distance Control Assist (DCA)” (P.5-
87).

The engine oil pressure warning light is not
designed to indicate a low oil level. Use the
dipstick to check the oil level. (See “Engine
oil” (P.8-6).)
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.

driving there may be a malfunction in
the 4WD system. Reduce the vehicle
speed and have your vehicle checked
as soon as possible. It is recom-
mended you visit an INFINITI retailer
for this service.
. If the 4WD warning light turns on
when driving on dry or hard surfaced
roads:

— in the 4L(O) position, stop the vehicle and shift the transmission
shift lever to the N (Neutral)
position and shift the 4WD shift

CAUTION
.Do not ground accessories directly to
the battery terminal. Doing so will
bypass the variable voltage control
system and the vehicle battery may
not charge completely.
. Use electrical accessories with the
engine running to avoid discharging
the vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage gen-
erated by the generator.
