ECU Acura RL 2007 Service Manual

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.Trailer lights and equipment must
comply with federal, state, and local
regulations. Check with your local
trailerdealerorrentalagencyforthe
requirements in your area, 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.

Tires marked ‘‘M S’’ or ‘‘All
Season’’ on the sidewall have an all-
weather tread design suitable for
most winter driving conditions.
For the best performance in snowy
or icy conditions, you should install
snow tires or tire chains. They may
be required by local laws under
certain conditions. Mount
tire chains on your tires when
required by driving conditions or
local laws. Install them only on the
front tires.
If
you mount snow tires on your
vehicle, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tires on all four wheels. The traction
provided by snow tires on dry roads
maybelowerthanyouroriginaltires.
Check with the tire dealer for
maximum speed recommendations. Because
your vehicle has limited tire
cl earance, Acura strongly
recommends using the chain listed
below, made by Security Chain
Company (SCC).
Tire chains cannot be used with a
flat front tire. If a front tire goes flat
when a tire chain is installed on it,
remove the chain, and f ollow the
precautions described under
Michelin PAX System (see page ).
