2009 HONDA RIDGELINE engine

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.
The maximum allowable weight of
the trailer and everything in or on it
depends on the number of occupants
in your vehicle and the type of trailer
being towed (see page ).
Towing a trailer that is too heavy can
seriously af f ect your vehicle’s
handling and perf ormance. It can
also damage the engine and
drivetrain.
Avoid towing a trailer during your
vehicle’s f irst 600 miles (1,000 km)
(see page ).
Be sure to read the
sectiononpage
if you plan to tow of f paved
surf aces.

If youmuststopwhenfacinguphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
place by pressing on the accelerator,
as this can cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed, and use D3. Do not
‘‘ride’’ the brakes.
Drive slower than normal in all
driving situations, and obey posted
speed limits f or vehicles with trailers.
When towing a f ixed-sided trailer
(e.g., camper), do not exceed 55 mph
(88 km/h). At higher speeds, the
trailer may sway or affect vehicle
handling.
Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause the trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.
When towing a trailer on level roads
under normal driving conditions, do
not use D3. This will increase the
automatic transmission fluid
temperature and may cause
overheating. Maketurnsmoreslowlyandwider
than normal. The trailer tracks a
smaller arc than your vehicle, and it
canhitorrunoversomethingthe
vehicle misses.
Allow more time and distance f or
braking. Do not brake or turn
suddenly as this could cause the
trailer to jackknif e or turn over.
When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning of f , reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
With heavy cargo on the pickup bed,
your vehicle has a higher center of
gravity. Drive slowly and cautiously,
and allow more time and distance f or
braking. Loading heavy cargo could
af f ect your vehicle’s handling and
perf ormance. Remember, it
takes longer to slow down and
stop when towing a trailer.T owing Speeds and Gears

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
