unobstructed. Remove f rost, snow,
or ice.
Check that the hood is f ully closed.
Check that any items you may be
carrying are stored properly or
f astened down securely. Visually check the tires. If a tire
looks low, use a gauge to check its
pressure. When you start the engine, check
the gauges and indicators in the

messages on the multi-inf ormation
display (see pages , and
).

Your vehicle still has normal f ront-
wheel drive with vehicle stability
assist (VSA), but does not have the
advantages of SH-AWD. Have your
vehicle checked by a dealer as soon
as possible.
If the SH-AWD indicator on the
instrument panel stays on, and the
‘‘CHECK SH-AWD SYSTEM’’
message also appears on the multi-
inf ormation display, there is problem
with the SH-AWD system.
If the SH-AWD indicator blinks while
driving, it indicates the dif f erential
temperature is too high. You will also
see an ‘‘SH-AWD DIFF TEMP
HIGH’’ message on the multi-
inf ormation display. If this happens,
pull to the side of the road when it is
saf e, shif t to Park, and let the engine
idle until the indicator goes out. If
the indicator does not go out, take
your vehicle to a dealer to have it
checked.
Each torque indicator is displayed as
a bar graph divided into 5 segments.
The number of segments represents
the amount of torque distributed to
each wheel.
When there is only a slight change in
torque distribution while driving,
such as cruising on level roads at the
same speed, the torque distribution
monitor may stop displaying the
amount of torque. This is not a
system problem. The monitor will
show the amount if the system
senses any change in torque
distribution.

Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly, or
your vehicle may roll if it is parked
on an incline.Make sure the moonroof and the
windows are closed.
If the vehicle is f acing uphill, turn
the front wheels away from the
curb.
If the vehicle is f acing downhill,
turn the front wheels toward the
curb.
Check the indicator on the
instrument panel to verif y that the
security system is set.
Make sure the parking brake is
f ully released bef ore driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.
Set the parking brake bef ore you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission.
Turn of f the lights.
Place any packages, valuables, etc.
in the cargo area or take them
with you.
Lock the doors and the tailgate.
Never park over dry leaves, tall
grass, or other f lammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.

Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist using negative pressure
generated by the engine and the
electric vacuum pump helps reduce
the ef f ort needed on the brake pedal.
The anti-lock brake system (ABS)
helps you retain steering control
when braking very hard.All f our brakes have audible brake
wear indicators.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness
and reduces brake pad life. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you.
When the electric vacuum pump is in
operation, it makes some mechanical
noises come f rom the engine
compartment. This is normal.
When you drive in cold weather or
thinner air at high altitude, the
electric vacuum pump operates more
f requently af ter the engine is started.
For more inf ormation about the
electric vacuum pump, see page . Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear.
Check your brakes af ter driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious and alert in your driving.

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
inf ormation display along with a
‘‘CHECK TIRE PRESSURE’’
message.Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly.
Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
Youshouldstopandcheckyourtires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle’s tire inf ormation
placard.
It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-inf ormation display go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible. 370

Trailer lights and equipment must
comply with f ederal, state/province,
and local regulations. Check with
your local trailer sales or rental
agencies f or the requirements in the
area where you plan to tow, and use
only equipment designed f or your
vehicle.
Acura requires that any trailer with a
total trailer weight of 1,000 lbs (455
kg) or more have its own brakes.
If you choose electric brakes, be
sure they are electronically actuated.
Do not attempt to tap into your
vehicle’s hydraulic system. No
matter how successf ul it may seem,
any attempt to attach trailer brakes
to your vehicle’s hydraulic system
will lower braking ef f ectiveness and
create a potential hazard.
Seeyourtrailerdealerorrental
agency f or more inf ormation on
installing electric brakes.
Any hitch used on your vehicle must
be properly bolted to the underbody.
Always use saf ety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and can catch the trailer if it
becomes unhitched. Leave enough
slack to allow the trailer to turn
corners easily, but do not let the
chains drag on the ground.

Many states and Canadian provinces
require special outside mirrors when
towing a trailer. Even if they don’t,
you should install special mirrors if
you cannot clearly see behind you, or
if the trailer creates a blind spot.
Askyourtrailersalesorrental
agency if any other items are
recommended or required f or your
towing situation.
Since lighting and wiring vary by
trailer type and brand, you should
have a qualif ied technician install a
suitable connector between the
vehicle and the trailer. Improper
equipment or installation can cause
damage to your vehicle’s electrical
system and af f ect your vehicle
warranty.
Your vehicle has a trailer lighting
connector located under the right
side tool case in the cargo area.
