2008 YAMAHA GRIZZLY 350 four wheel drive

7-18
7When this ATV is in 4WD (for four-wheel-drive
models), all wheels (front and rear) are intercon-
nected by the drive train. This means that applying
either the front brake or the rear brake will brake all
wheels. When descending hills, using either brake
lever or the brake pedal will brake the wheels on
the downhill side. Avoid sudden application of ei-
ther the front or rear brake because the wheels on
the uphill side could come off the ground. Apply
both the front and rear brakes gradually.
Whenever possible, ride your ATV straight down-
hill. Avoid sharp angles which could allow the ATV
to tip or roll over. Carefully choose your path and
ride no faster than you will be able to react to ob-
stacles which may appear.
WARNING
EWB01620Always follow proper procedures for going
down hills as described in this Owner’s Manu-
al.
Note: a special technique is required when
braking as you go down a hill.
Always check the terrain carefully before
you start down any hill.
Shift your weight backward.
Never go down a hill at high speed.

Avoid going down a hill at an angle that
would cause the ATV to lean sharply to one
side. Go straight down the hill where possi-ble.
CROSSING A SLOPE
Traversing a sloping surface on your ATV requires
you to properly position your weight to maintain
proper balance. Be sure that you have learned the
basic riding skills on flat ground before attempting
