●
When deflection or tension of belt being used exceeds “Used belt limit”, adjust it to value for
“After adjustment of used belt”.
●
When checking belt deflection or tension immediately after installation, first adjust it to the speci-
fied value. Then, after turning the crankshaft two turns or more, re-adjust to the specified value to
avoid variation in deflection between pulleys.
●
When installing belt, make sure that it is correctly engaged with pulley groove.
●
Keep oil and water away from belt.
●
Do not twist or bend belt excessively.

WARNING:
●
To avoid being scalded, never change the engine coolant when the engine is hot.
●
Wrap a thick cloth around cap and carefully remove the cap. First, turn the cap a quarter of a turn
to release built-up pressure. Then turn the cap all the way.
DRAINING ENGINE COOLANT
1.
Remove radiator drain hole cap from engine undercover.
2.
Open radiator drain plug at the bottom of radiator and remove
the radiator filler cap.
●
Be careful not to allow engine coolant to contact the drive
belts.
3.
When draining all of the engine coolant for engine removal or
repair, open the drain plugs on the engine-right and left sides
and the engine-front side.

minutes for the transmission fluid to warm up to 50 - 80
°
C (122 -
176
°
F).
3.
Park the vehicle on a level surface.
4.
Apply parking brake firmly.
5.
With engine at idle, while depressing brake pedal, move shift
selector throughout the entire shift range.
6.
Pull out the dipstick from the CVT fluid charging pipe after press-
ing the tab on the dipstick to release the lock.
7.
Wipe fluid off the dipstick and rotate the dipstick attached for
180
°
to securely insert the dipstick until it meets the end of the
CVT fluid charging pipe.

Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:
●
Be careful not to scratch the road wheel during removal.
●
After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
WHEEL BALANCE ADJUSTMENT
●
If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for road wheels.
1.
Set road wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.
2.
When inner and outer unbalance values are shown on the wheel balancer indicator, multiply outer unbal-
ance value by 5/3 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:
●
Do not install the inner balance weight before installing the outer balance weight.
●
Before installing the balance weight, be sure to clean the
mating surface of the road wheel.
Indicated unbalance value
×
5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz)
×
5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance
weight (closer to calculated balance weight value)
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 = 35 g (1.23 oz)
37.5 = 40 g (1.41 oz)

balancer indication position (angle).
CAUTION:
●
Always use genuine Nissan adhesion balance weights.
●
Balance weights are unreusable; always replace with new
ones.
●
Do not install more than three sheets of balance weight.
c.
If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other (as shown in
the figure).
CAUTION:
Do not install one balance weight sheet on top of another.
3.
Start wheel balancer again.
4.
Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).
CAUTION:
Do not install more than two balance weights.
5.
Start wheel balancer. Make sure that inner and outer residual
unbalance values are 10 g (0.35 oz) each or below.
