2008 HONDA RIDGELINE traction control

The vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surf aces. It does this
by regulating the engine’s output and
by selectively applying the brakes.
The VSA system cannot enhance the
vehicle’s driving stability in all
situations and does not control your
vehicle’s entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. There may also
be some noise f rom the VSA
hydraulic system. You will also see
the VSA activation indicator blink.When VSA activates, you will see the
VSA activation indicator blink (see
page ).
If the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehicle as
soon as possible.
If this indicator comes on while
driving, pull to the side of the road
when it is saf e, and turn of f the
engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on or comes
back on while driving, have the VSA
system inspected by your dealer. If the low tire pressure indicator or
TPMS indicator comes on, the VSA
system automatically turns on even
when the VSA system is turned of f
by pressing the VSA OFF switch
(see page ). If this happens, you
cannot turn the VSA system of f by
pressing the VSA of f switch again.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.

In certain unusual conditions when
your vehicle gets stuck in shallow
mud or f resh snow, it may be easier
to free it with the VSA temporarily
switched of f . When the VSA system
is of f , the traction control system is
alsooff.Youshouldonlyattemptto
f ree your vehicle with the VSA of f if
you are not able to f ree it when the
VSA is on.Driving with varying tire or wheel
sizes may cause the VSA to
malf unction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page ).
If you install winter tires, make sure
they are the same size as those that
were originally supplied with your
vehicle. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
VSA.
This switch is above the parking
brake release handle. Press it to turn
the VSA system on and of f .
When VSA is off, the VSA activation
indicator comes on as a reminder.
VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.
Immediately af ter f reeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.

Towing a load that is too heavy can
seriously af f ect your vehicle’s
handling and perf ormance.
Your vehicle has been designed to
tow a trailer, as well as carrying
passengers and their cargo. To
saf ely tow a trailer, you should
caref ully observe the load limits (see
page ), use the proper equipment,
and f ollow the guidelines in this
section.
Be sure to read the
sectiononpage
if you plan to tow of f paved
surf aces.
The weight that the tongue of a f ully-
loaded trailer puts on the hitch
should f ollow the recommended load
guidelines (see page ). Too
much tongue load reduces f ront-tire
traction and steering control. Too
little tongue load can make the
trailer unstable and cause it to sway.

Exceeding any load limit or

Before you leave the pavement, be
sure to do all scheduled maintenance
and service, and inspect your vehicle
f or any problems. Pay special
attention to the condition of the tires,
and check the tire pressures.
After you return to the pavement,
caref ully inspect your vehicle to
make sure there is no damage that
could make driving it unsaf e.
Recheck the condition of the tires
and the tire pressures.
The route presents limits (too steep
or bumpy roads). You have limits
(driving skill and comfort). And your
vehicle has limits (traction, stability,
and power).
Driving of f -highway can be
hazardous if you f ail to recognize
limits and take the proper
precautions.
To avoid loss of control or rollover,
be sure to f ollow all precautions and
recommendations.
Be sure to store cargo properly
and do not exceed your cargo load
limits (see page and ).
Be aware that a heavy load can
reduce ground clearance and your
ability to clear obstacles.
Whenever you drive, make sure
you and your passengers always
wear seat belts.
Keep your speed low, and never
go faster than the conditions allow.
It’s up to you to continually assess
the situation and drive within the
limits. 191217

The banks and surf ace under the
water provide good traction. The
water may hide hazards such as
rocks, holes, or mud.
Bef ore driving through water, stop,
get out if necessary, and make sure
that:
If you decide it is saf e to drive
through water, choose a suitable
speed, and proceed without shif ting,
changing speeds, stopping, or
shutting of f the engine.
Do not try to cross water at high
speeds, as this may cause severe
damage to the cooling system or
result in loss of control.
After driving through water, test
your brakes. If they got wet, gently
‘‘pump’’ them while driving slowly
until they operate normally.
If the water is deeper than the wheel
hubs, some additional service may
be required. This service is not
covered by your warranties.
The water is not f lowing too f ast.
Deep rushing water can sweep you
downstream. Even very shallow
rushingwatercanwashthe
ground f rom under your tires and
cause you to lose traction and
possibly roll over.
The banks are sloped so you can
drive out.
The water is not deep enough to
cover your wheel hubs, axles, or
exhaust pipe. You could stall and
not be able to restart your engine.
The water can also damage
important vehicle components. If you get stuck, and cannot get
unstuck with the VTM-4 system,
engage the VTM-4 Lock (see page
), and carefully try to go in the
direction (f orward or reverse) that
you think will get you unstuck. Do
notspinthetiresathighspeeds.It
will not help you get out and may
cause damage to the transmission or
VTM-4 system.
If you are still unable to f ree yourself ,
your vehicle is equipped with f ront
and rear tow hooks designed f or this
purpose (see page ). 299

The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied government
test course. For example, a tire
graded 150 would wear one and one-
half (1 1/2) times as well on the
government course as a tire graded
100. The relative perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices and dif f erences in
road characteristics and climate.The traction grades, f rom highest to
lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
Quality grades can be f ound where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades.
