it rolls forward, backward or side-
ways, you could be injured.
. Whenever you drive off-road
through sand, mud or water as deep
as the wheel hub, more frequent
maintenance may be required. See
the maintenance schedules shown in
the "9. Maintenance and schedules"
section.
. Spinning the rear wheels on slippery
surfaces may cause the 4WD warn-
ing light to flash. The 4WD system
may also automatically switch from
the 4WD mode to the 2WD mode.
This could reduce traction. Be espe-
cially careful when towing a trailer
(4WD models).WARNING

consecutive times or the ignition switch
is pushed and held for more than 2
seconds.) If the engine stops while the
vehicle is being driven, this could lead to
a crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the shift lever to the
P (Park) position.

is located above the inside mirror.
To keep the proper operation of the LDW
system and prevent a system malfunction,
be sure to observe the following:
. Always keep the windshield clean.
. Do not attach a sticker (including trans-
parent material) or install an accessory
near the camera unit.
. Do not place reflective materials, such as
white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane markers. .
Do not strike or damage the areas around
the camera unit. Do not touch the
camera lens or remove the screw located
on the camera unit. If the camera unit is
damaged due to an accident, it is re-
commended that you visit an INFINITI
