including engine exhaust, carbon monoxide, phthalates, and
lead, which are known to the State of California to cause
cancer and birth defects or other reproductive harm. To
minimize exposure, avoid breathing exhaust, do not idle the
engine except as necessary, service your vehicle in a well-
ventilated area and wear gloves or wash your hands
frequently when servicing your vehicle. For more information

ON-PAVEMENT AND OFF-
ROAD DRIVING
This vehicle will handle and maneuver
differently from an ordinary passenger car
because it has a higher center of gravity
for off-road use. As with other vehicles
with features of this type, failure to
operate this vehicle correctly may result in
loss of control or an accident. Be sure to
read “On-pavement and off-road driving
precautions”, “Avoiding collision and roll-
over” and “Driving safety precautions” in
the “5. Starting and driving” section of this
manual.
Foreword

MODIFICATION OF YOUR VEHI-
CLE
This vehicle should not be modified. Mod-
ification could affect its performance,
safety or durability, and may even violate
governmental regulations. In addition, da-
mage or performance problems resulting
from modification will not be covered
under the INFINITI warranties.
WARNING

agnostic (OBD) plug-in device that uses
the port during normal driving, for
example remote insurance company
monitoring, remote vehicle diagnostics,
telematics or engine reprogramming,
may cause interference or damage to
vehicle systems. We do not recommend
or endorse the use of any aftermarket
OBD plug-in devices, unless specifically
approved by INFINITI. The vehicle war-
ranty may not cover damage caused by
any aftermarket plug-in device.
