WARNING LIGHTS
All-Wheel Drive (AWD) warning
light (AWD models)
Thewarning light comes on when the
ignition switch is pushed to ON. It turns off
soon after the engine is started.
If the AWD system malfunctions, or the
diameter of the front and the rear wheels
are different, the warning light will either
remain illuminated or blink. (See “All-
Wheel Drive (AWD)” (P.5-76).)
CAUTION
.If the warning light comes on while
driving there may be a malfunction in
the AWD system. Reduce the vehicle
speed and have your vehicle checked by
an INFINITI retailer as soon as possible.
. If the AWD warning light blinks on when
you are driving:
—blinks rapidly (about twice a sec-
ond):
Pull off the road in a safe area, and
idle the engine. The driving mode will
change to 2WD to prevent the AWD
system from malfunctioning. If the warning light turns off, you can drive
again.
—blinks slowly (about once every 2
seconds):
Pull off the road in a safe area, and
idle the engine. Check that all tire
sizes are the same, tire pressure is
correct and tires are not worn.
. If the warning light is still on after the
above operations, have your vehicle
checked by an INFINITI retailer as soon
as possible.
orAnti-lock Braking
System (ABS) warning light
When the ignition switch is in the ON
position, the Anti-lock Braking System
(ABS) warning light illuminates and then
turns off. This indicates the ABS is opera-
tional.
If the ABS warning light illuminates while
the engine is running, or while driving, it
may indicate the ABS is not functioning
properly. Have the system checked by an
INFINITI retailer.
If an ABS malfunction occurs, the anti-lock
function is turned off. The brake system then operates normally, but without anti-
lock assistance. (See
“Brake system”(P.5-
80).)
Automatic transmission check
warning light
When the ignition switch is pushed to the
ON position, the light comes on for 2
seconds. If the light comes on at any other
time, it may indicate the transmission is
not functioning properly. Have your INFINITI
retailer check and repair the transmission.
orBrake warning light
This light functions for both the parking
brake and the foot brake systems.
Parking brake indicator:
When the ignition switch is in the ON
position, the light comes on when the
parking brake is applied.
Low brake fluid warning light:
When the ignition switch is in the ON
position, the light warns of a low brake
fluid level. If the light comes on while the
engine is running with the parking brake
not applied, stop the vehicle and perform
the following:
1. Check the brake fluid level. If brake

fluid is necessary, add fluid and have
the system checked by your INFINITI
retailer. (See“Brake fluid” (P.8-16).)
2. If the brake fluid level is correct, have the warning system checked by an
INFINITI retailer.
Anti-lock Braking System (ABS) warning
indicator:
When the parking brake is released and
the brake fluid level is sufficient, if both
the brake warning light and the Anti-lock
Braking System (ABS) warning light illumi-
nate, it may indicate the ABS is not
functioning properly. Have the brake sys-
tem checked, and if necessary repaired, by
an INFINITI retailer promptly. (See “Anti-
lock Braking System (ABS) warning light”
(P.2-14).)
WARNING
. Your brake system may not be working
properly if the warning light is on.
Driving could be dangerous. If you judge
it to be safe, drive carefully to the
nearest service station for repairs.
Otherwise, have your vehicle towed
because driving it could be dangerous. .
Pressing the brake pedal with the
engine stopped and/or low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort as well as pedal travel.
. If the brake fluid level is below the
minimum or MIN mark on the brake fluid
reservoir, do not drive until the brake
system has been checked at an INFINITI
retailer.
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, see an INFINITI
retailer immediately.
CAUTION
Do not continue driving if the alternator belt
is loose, broken or missing.

tion 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 at an INFINITI retailer.
Engine oil pressure warning
light
This light warns of low engine oil pressure.
If the light flickers or comes on during
normal driving, pull off the road in a safe
area, stop the engine immediatelyand call
an INFINITI retailer or other authorized
repair shop.
The engine oil pressure warning light is
not designed to indicate a low oil level.
Use the dipstick to check the oil level. (See
Instruments and controls2-15

2-16Instruments and controls
“Engine oil”(P.8-11).)
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 covered
by warranty. Turn off the engine as soon as
it is safe to do so.

system warning light (orange; if so
equipped)
This light comes on if there is a malfunc-
tion in the Intelligent Cruise Control (ICC)
system.
If the warning light comes on, park the
vehicle in a safe place. Turn the engine off,
restart the engine, resume driving and set
the ICC system again.
If it is not possible to set the system or the
indicator stays on, it may indicate that the
system is malfunctioning. Although the
vehicle is still driveable under normal
conditions, have the vehicle checked at
an INFINITI retailer.

(orange; if so equipped)
When the ignition switch is pushed to the
ON position, the light will come on in
orange, turn green, and then turn off. This
indicates that the Lane Departure Warning
(LDW) and Lane Departure Prevention (LDP)
systems are operational.
While the LDW and/or LDP system is on,
the light will blink in orange and a warning
chime will sound if the vehicle is traveling
close to either the left or the right of a
traveling lane with detectable lane mar-
kers. If the light comes on in orange and remains
on, it may indicate that the LDW and LDP
systems are not functioning properly.
Although the vehicle is still driveable, have
the systems checked by an INFINITI retailer.
