CAUTION
nCaution while towing
lUse extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive stress on
the emergency towing eyelets and the cables or chains. Always be cautious of the
surroundings and other vehicles while towing.
lIf the engine is not running, the power assist for the brakes and steering will not
function, making steering and braking more difficult.
nInstalling towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing. This may
lead to accidents that cause serious injury or even death.

The California Air Resources Board
(CARB) and Lexus are pleased to
explain the emission control system
warranty for your 201 1 vehicle. In
California, new motor vehicles must
be designed, built and equipped to
meet the state’s stringent anti-smog
standards. CARB regulations require
that Lexus must warrant the emission
control system on your vehicle for the
time periods indicated on the next
page, provided there has been no
abuse, neglect or improper mainte-
nance of your vehicle.
Your emission control system may
include parts such as the fuel injection
system, ignition system, catalytic con-
verter and engine computer. Also
included may be hoses, belts, connec-
tors and other emissions-related
assemblies.
Where a warrantable condition exists,
Lexus will repair your vehicle at no
cost to you, including diagnosis, parts
and labor.
