5. Check behind you, then release the brakepedal and press the accelerator pedal
gradually.
6. Continue to watch to the rear while driv- ing in reverse.EBU36733Launch system operationThe launch system allows you to start off at a
higher engine speed, and thus have a higher
initial acceleration rate than normal operation.
Only use the launch system on level ground
with a clear and safe path ahead of you.TIPThe launch system will be prevented from op-
erating if any of the following conditions are
present:
the engine is not warmed up or is overheat-
ing.
 the driver seat belt is not latched.
 the differential gear is locked (“DIFF LOCK”
is selected) or the differential gear lock indi-
cator is flashing. 
the parking brake is applied.
 an engine or system malfunction is detect-
ed (a warning light is on).
To activate the launch system1. Confirm that the front wheels and steer-
ing wheel are pointed straight ahead.

by a Yamaha dealer.
EBU35121Checking the spark plugsThe spark plug is an important engine com-
ponent which should be periodically
checked, preferably by a Yamaha dealer.
Since heat and deposits will cause any spark
plug to slowly erode, the spark plugs should
be removed and checked in accordance with
the periodic maintenance chart for the emis-
sion control system. In addition, the condition
of the spark plugs can reveal the condition of
the engine.

TIPService the air filters more frequently when
operating in wet or dusy 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 panel C (page 8-10).
2. 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.

Place a thick rag over the cap and remove the cap slowly to allow any re-
maining pressure to escape.
TIPIf it is difficult to get the recommended coolant, tap water can be used temporarily, provided that
it is changed to the recommended coolant as soon as possible. Wait until the
engine has cooled.
Check the coolant level in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
