2010 INFINITI QX ABS

This procedure is described in the vehicle service
manual and can be performed by an INFINITI
dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front
of you. Ultimately, the driver is respon-
sible for safety.
● Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the specified size of tires on all four
wheels. – When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. See “Tire and
Loading Information label” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h) . The speed varies according to road
conditions.
When the ABS senses that 1 or more wheels are
close to locking up, the actuator rapidly applies
and releases hydraulic pressure. This action is
similar to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal and hear a
noise from under the hood or feel a vibration from
the actuator when it is operating. This is normal
and indicates that the ABS is operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake

pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by an INFINITI dealer.The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving situations, the
system will control braking and engine output to
help keep the vehicle on its steered path.
● When the Vehicle Dynamic Control (VDC)
system is operating, the slip indicator in the
instrument panel blinks.
● If the slip indicator blinks, the road condi-
tions may be slippery. Be sure to adjust your
speed and driving to these conditions. See
“Slip indicator light”, and “Vehicle Dynamic
Control (VDC) off indicator light” in the “In-
struments and controls” section.
● Indicator light
– If a malfunction occurs in the system, the SLIP and
indicator lights come on
in the instrument panel.
– If the 4WD transfer case is shifted into 4LO the
indicator light will come
on and the VDC system will be turned off.
See “Transfer case shifting procedures”
earlier in this section.
– As long as these indicator lights are on, the traction control function is canceled. If the vehicle is operated with the Vehicle Dy-
namic Control system off using the VDC OFF
switch, most VDC and Traction Control System
(TCS) functions will be turned off. The
SLIP
indicator will flash if wheel spin is detected. The
ABS will still operate with the VDC system off.
When the VDC system is operating, you may feel
a pulsation in the brake pedal and hear a noise or
vibration from under the hood. This is normal and
indicates that the VDC system is working prop-
erly.
The computer has a built in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in reverse
at a slow speed. When the self-test occurs, you
may hear a clunk noise and/or feel a pulsation in
the brake pedal. This is normal and is not an
indication of a malfunction.

CAUTION
●Special hitches which include frame re-
inforcements are required for towing
above 2,000 lb (907 kg) . Suitable genu-
ine INFINITI hitches, ball mounts and
hitch balls for pickup trucks and sport
utility vehicles are available at an
INFINITI dealer.
● The hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.
● Do not use axle-mounted hitches.
● Do not modify the vehicle exhaust sys-
tem, brake system, etc. to install a
trailer hitch.
● To reduce the possibility of additional
damage if your vehicle is struck from
the rear, where practical, remove the
receiver when not in use.
● Regularly check that all trailer hitch
mounting bolts are securely mounted.
● When towing with the hitch ball
mounted to the rear bumper, do not
make sharp turns. The trailer may con-
tact the bumper and cause damage to
the bumper or trailer.
Tire pressures
● When towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the tire
placard.
● Trailer tire condition, size, load rating
and proper inflation pressure should
be in accordance with the trailer and
tire manufacturer’s specifications.
Safety chains
Always use suitable safety chains between your
vehicle and the trailer. The safety chains should
be crossed and should be attached to the hitch,
not to the vehicle bumper or axle. The safety
chains can be attached to the bumper if the hitch
ball is mounted to the bumper. Be sure to leave
enough slack in the chains to permit turning
corners.
Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available power-
type module/converter must be used to
provide power for all trailer lighting. This
unit uses the vehicle battery as a direct
power source for all trailer lights while
using the vehicle tail light, stoplight and
turn signal circuits as a signal source. The
module/converter must draw no more
that 15 milliamps from the stop and tail
lamp circuits. Using a module/converter
that exceeds these power requirements
may damage the vehicle’s electrical sys-
tem. See a reputable trailer dealer to ob-
tain the proper equipment and to have it
installed.
Trailer lights should comply with federal and/or
local regulations. For assistance in hooking up
trailer lights, contact an INFINITI dealer or repu-
table trailer dealer. Vehicles equipped with the
optional trailer tow package are equipped with a
7-pin trailer harness connector. If your trailer is
equipped with a flat 4-pin connector, an adapter
will be needed to connect the trailer lights to the
vehicle. Adapters are available at auto parts
stores and hitch retailers.
