Larger or smaller wheels and tires
can interf ere with the operation of
your vehicle’s anti-lock brakes and
other systems.
Modif ying your steering wheel or
any other part of your vehicle’s
saf ety systems could make the
systems inef f ective.
If you plan to modif y your vehicle,
consult your dealer.
Raising your vehicle with a non-
Acura suspension kit can af f ect
the handling and stability.
Lowering the vehicle with a non-
Acura suspension kit that
signif icantly reduces ground
clearance can allow the
undercarriage to hit speed bumps
or other raised objects, which
could cause the airbags to deploy.
Removing parts f rom your vehicle,
or replacing components with non-
Acura components could seriously
af f ect your vehicle’s handling,
stability, and reliability.
Herearesomeexamples:
Non-Acura wheels, because they
are a universal design, can cause
excessive stress on suspension
components and will not be
compatible with the tire pressure
monitoring system (TPMS).

The radar sensor is located behind
the Acura emblem in the f ront grille.
If the emblem is covered with mud,
dirt, dead leaves, wet snow, etc., or if
you put a sticker on it, the CMBS will
automatically shut off, and the
CMBS indicator on the instrument
panel will come on. You will also see
a CHECK CMBS RADAR SENSOR
message on the multi-inf ormation
display f or about 5 seconds.Always keep the emblem clean. If it
gets dirty, clean it with water or a
mild detergent. Never use chemical
solvents or polishing powder.Do not allow anything to impact the
radar sensor or the emblem. If either
of these parts receives a strong
impact, turn off the system by
pressing the CMBS of f switch, and
have your vehicle checked by a
dealer. If the f ront grille ever needs
to be repaired, consult a dealer f irst.
There are three bolts on the sides of
the radar sensor. Do not tamper with
these bolts, or you may cause the
system to malf unction. If the f ront emblem or the radar
sensor ever needs to be removed,
take your vehicle to a dealer.

To achieve a proper tongue load,
start by loading 60 % of the load
toward the front of the trailer and
40 % toward the rear, then re-adjust
the load as needed.The maximum allowable weight of
the vehicle, all occupants, all
accessories, all cargo, and the
tongue load is: 4,980 lbs (2,260 kg)
The maximum allowable weight of
the vehicle axles are: 2,680 lbs
(1,215 kg) on the f ront axle, and
2,380 lbs (1,080 kg) on the rear
axle. Towing generally requires a variety
of supplemental equipment,
depending on the size of your trailer,
how much load you are towing, and
where you tow. To ensure the best
quality, we recommend that you
purchase Acura equipment
whenever possible.
Discuss your needs with your trailer
sales or rental agency, and f ollow the
guidelines in the rest of this section.
Also make sure that all equipment is
properly installed and maintained,
and that it meets f ederal, state,
province, and local regulations.
Any hitch used on your vehicle must
be properly bolted to the underbody.
Thebestwaytoconfirmthatall
loads are within limits is to check
them at a public scale. For public
scales in your area, check your local
phone book, or contact your trailer
dealer or rental agency for
assistance.
If you cannot get to a public scale,
you can estimate the total trailer
weight by adding the weight of your
trailer (as quoted by the
manuf acturer) with everything in or
on the trailer.
If you normally pull the same load
each time you tow a trailer, you can
use a suitable scale or a special
tongue load gauge to check the
tongue load the f irst time you set up
a towing combination (a f ully loaded
vehicle and trailer), then recheck the
tongue load whenever the conditions
change.

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.Acura recommends that any trailer
having a total weight of 1,000 lbs
(450 kg) or more be equipped with
its own electric or surge-type 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.

installing electric brakes.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.
Since lighting and wiring vary by
trailer type and brand, you should
have a qualified 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.

In addition to proper inf lation,
correct wheel alignment helps to
decrease tire wear. If you f ind a tire
is worn unevenly, have your dealer
check the wheel alignment.
Have your dealer check the tires if
you f eel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed f rom the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comf ort and tire lif e. For best results,
have the installer perform a dynamic
balance.Replace your tires with radial tires of
the same size, load range, speed
rating, and maximum cold tire
pressure rating (as shown on the
tire’s sidewall).
Mixing radial and bias-ply tires on
your vehicle can reduce braking
ability, traction, and steering
accuracy. Using tires of a dif f erent
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
To help increase tire lif e and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the multi-information display. Move
the tires to the positions shown in
the illustration each time they are
rotated. If you purchase directional
tires, rotate only front-to-back.
When the tires are rotated, make
sure the air pressures are checked. Your vehicle is not designed f or
Michelin PAX system wheels or tires.
Use only the wheels and tires
designated in this owner’s manual.
Never mix conventional wheels or
tires with PAX system wheels or
tires.
