ignition switch to the ON (II)
position.
Itcomesonasareminderthatyou
have turned off the adaptive front
lighting system (AFS).
This indicator blinks when there is a
problem with the AFS system; you
will also see a ‘‘CHECK ADAPTIVE
FRONT LIGHTING SYSTEM’’
message on the multi-inf ormation
display (see page ). If this
happens, stop the vehicle in a saf e
place, turn the ignition switch to the
ACCESSORY (I) or the LOCK (0)
position, and restart the engine. If

the collision mitigation brake system
(CMBS).
The CMBS indicator also comes on
if dirt or other debris blocks the
radar sensor in the f ront grille. You
will also see a ‘‘CHECK CMBS
RADAR SENSOR’’ message on the
multi-inf ormation display. When you
clean the radar sensor, the indicator
should go of f the next time you turn
the ignition switch to the ON (II)
position.
If the indicator comes on at any

If the AFS indicator comes on and
starts blinking while driving, pull to
the side of the road when it is saf e,
andturnoff theengine.If theAFS
indicator keeps blinking, or starts
blinking again while driving af ter
turning the ignition switch to the ON
(II) position, the AFS is not working
properly (see page ). Have the
AFS inspected by your dealer.
When the AFS indicator comes on,
you will also see a ‘‘CHECK
ADAPTIVE FRONT LIGHTING
SYSTEM’’ message on the multi-
inf ormation display (see page ).
Without AFS, your vehicle still has
normal lighting ability to continue
driving.
The adaptive f ront lighting system
(AFS) helps to improve visibility
during nighttime driving. The AFS
controls the aiming direction and
lighting distribution of the low
beams according to the amount of
turn applied to the steering wheel
during cornering or turning. Press
the AFS OFF switch to turn the AFS
on and off when the ignition switch
is in the ON (II) position and the
headlights are turned on.

soon as possible (see page ).
The engine does not restart if you
turn the ignition switch to the LOCK
(0) position when the remote is
outside the vehicle. Check where the
remote is. Make sure that you carry
the remote or built-in key with you

Park the vehicle, and set the
parking brake. Pull the hood
release lever located under the
lower lef t corner of the dashboard.
The hood will pop up slightly.
Your vehicle’s on board diagnostic
system will detect a loose or missing
f uel f ill cap as an evaporative system
leak. The f irst time a leak is detected
a ‘‘TIGHTEN FUEL CAP’’ message
appears on the multi-inf ormation
display. Turn the engine of f , and
conf irm the f uel f ill cap is installed. If
it is, loosen it, then retighten it until
it clicks at least once. The message
should go of f af ter several days of
normal driving once you tighten or replace the f uel f ill cap. To scroll to
another message, press the INFO
button. The ‘‘TIGHTEN FUEL CAP’’
message will appear each time you
restart the engine until the system
turns the message of f .
If the system still detects a leak in
the vehicle’s evaporative emissions
system, the malf unction indicator
lamp (MIL) comes on. If the f uel f ill
cap was not already tightened, turn
the engine of f , and check or
retighten the f uel f ill cap until it
clicks at least once. The MIL should
go off after several days of normal
driving once the cap is tightened or
replaced. If the MIL does not go of f ,
have your vehicle inspected by a
dealer. For more inf ormation, see

Cold engine operation (engines

Driving with a heavy load or the
air conditioner running
Improperly inf lated tires
An under-inf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
It puts a heavier
load on the engine, increasing f uel
consumption. In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your f uel
economy.
The f ollowing f actors can lower your
vehicle’s f uel economy:
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the multi-
inf ormation display (see
on page ).
For example: Idling
results in 0 miles per gallon. If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
Aerodynamic drag has a big ef f ect
on f uel mileage at speeds above 45
mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.

Reset trip counter to zero.
Record the total gallons (liters) needed to ref ill.
Follow one of the simple calculations above.
Direct calculation is the
recommended source of inf ormation
about your actual f uel economy.
Using f requency of f ill-ups or taking
f uel gauge readings are NOT
accurate measures of f uel economy.
Fuel economy may improve over the
f irst several thousand miles. The A/C
puts an extra load on the engine
which makes it use more f uel. Use
the f resh-air ventilation when
possible.
Combine several short trips into
one. A warmed-up engine is more
f uel ef f icient than a cold one.
