Pavement
This vehicle is designed for off-road use only.
Avoid paved surfaces. Turn gradually and go
slowly if you must drive on pavement.
Water
If you must cross shallow, slow-moving water
up to the depth of the vehicle’s floorboard,
choose your path carefully to avoid sharp
drop-offs, large rocks, or slippery surfaces
that could cause the vehicle to overturn. Nev-
er operate through water deeper than 40 cm
(16 in) or fast-flowing water. Choose a path
where both your entrance into and exit point
from the water is a gradual incline. Determine
the water depth and currents before crossing.
Operating this vehicle through deep or fast-
flowing water can lead to loss of control or
overturn. To reduce your risk of drowning or
other injuries, use care when crossing
through water.Wet brakes may have reduced effectiveness.
After leaving the water, test the brakes. If nec-
essary, apply the brakes several times to let
friction dry them out.
NOTICEECB02950After driving your vehicle in water, be sure
to drain the trapped water by removing the
check hoses at the bottom of the air filter
case. Wash the vehicle in fresh water if it
has been operated in salt water or muddy
conditions. Loose terrain/slippery terrain
When driving on slippery terrain, including
wet, muddy, or icy conditions, as well as
loose gravel, be aware that you could begin
skidding or sliding. To avoid loss of control,
slow down and put the vehicle in four-wheel
drive before driving on a slippery surface and
plan your path to avoid making abrupt ma-
neuvers.

EBU38320Air filter maintenanceThis model is equipped with two air filter ele-
ments, a primary foam-type air filter and a
secondary paper-type air filter.
The primary air filter is easily accessed and
should be cleaned and oiled every 300–600
km (200–400 mi).
The secondary air filter is more difficult to ac-
cess, cannot be cleaned, and should be re-
placed by a Yamaha dealer every 2000–5000
km (1200–3000 mi).
TIPService the air filters more frequently when
operating in wet or dusty environments. Whenever air filter maintenance is performed:
check the air inlet for obstructions and the
air filter case for dirt and foreign matter.
check the air filter case check hoses for dirt
or water and clean as necessary.
check the air filter cas e joints and the rub-
ber joints to and from the throttle body for
proper fit and sealing.
tighten all fittings securely to avoid the pos-
sibility of unfiltered air entering the engine.NOTICEECB02270Never operate the engine with the air filter
element removed. Doing so would allow
unfiltered air to enter, causing rapid en-
gine wear and possible engine damage.

Additionally, the fuel injection system
would be affected, resulting in poor engine
performance and possible overheating. Clean the primary air filter as follows. 1. Remove the air filter case cover by turn- ing the air filter case cover lock counter-
clockwise.TIPMake sure that the match mark on the cover
lock is aligned with the open match mark on
the air filter case cover.

3. Remove the foam air filter element fromthe air filter frame. 4. Wash the foam material gently but thor-
oughly in parts cleaning solvent.
WARNING! Using gasoline or other
flammable solvents to clean the air fil-
ter element can cause a fire or explo-
sion, which could lead to serious
injury.

8. Allow the foam air filter to dry thoroughly.Inspect for wear and tear and replace if
damaged or heavily worn. 9. Thoroughly apply Yamalube foam air filter
oil (or other quality liquid foam air filter—
do not use a spray-type product) to the
foam material. The foam air filter element
should be wet but not dripping.
10. Pull the foam air filter element over its frame.
11. Install the air filter.
12. Install the air filter case cover and lock it
