FOR USA AND CANADA: Engine Oil Recommendation

NISSAN recommends the use of an energy conserving oil in order to improve fuel economy. Select only engine oils that meet the American Petroleum Institute (API) certification and International Lubricant Standardization and Approval Committee (ILSAC) certification and SAE viscosity standard. These oils have the API certification mark on the front of the container. Oils which do not have the specified quality label should not be used as they could cause engine damage.

Scheme 28

FOR USA AND CANADA: Engine Coolant Mixture Ratio

The engine cooling system is filled at the factory with a pre-diluted mixture of 50% Genuine NISSAN Long Life Antifreeze/Coolant (blue) and 50% water to provide year-round anti-freeze and coolant protection. The antifreeze solution contains rust and corrosion inhibitors. Additional engine cooling system additives are not necessary.

FOR MEXICO: Engine Coolant Mixture Ratio

The engine cooling system is filled at the factory with a high-quality, year-round and extended life engine coolant. The high quality engine coolant contains the specific solutions effective for the anti-corrosion and the anti-freeze function. Therefore, additional cooling system additives are not necessary.

When checking the engine coolant mixture ratio by the coolant hydrometer, use the chart below to correct your hydrometer reading (specific gravity) according to coolant temperature.

Scheme 49

Scheme 50

1. Set road wheel on balancer machine using the center hole as a guide. Start the balancer machine.
2. For balancer machines that only have a clip-on (rim flange) weight mode setting, follow this step to calculate the correct size adhesive weight to use. When inner and outer imbalance values are shown on the balancer machine indicator, multiply outer imbalance value by 5/3 (1.67) to determine balance weight that should be used. Select the outer balance weight with a value closest to the calculated value above and install in to the designated outer position of, or at the designated angle in relation to the road wheel. Indicated imbalance value x 5/3 (1.67) = balance weight to be installed Calculation example: 23 g (0.81 oz) x 5/3 (1.67) = 38.33 g (1.35 oz) --> 40 g (1.41 oz) balance weight (closer to calculated balance weight value) NOTE: 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)
3. Install balance weight in the position shown below. 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. When installing balance weight (1) to road wheel, set it into the grooved area (A) on the inner wall of the road wheel as shown below so that the balance weight center (B) is aligned with the balancer machine indication position (angle) (C). CAUTION: Always use genuine NISSAN adhesive balance weights. Balance weights are non-reusable; always replace with new ones. Do not install more than three sheets of balance weight.
4. If calculated balance weight value exceeds 50 g (1.76 oz), install two balance weight sheets in line with each other as shown below. CAUTION: Do not install one balance weight sheet on top another.
5. Start balancer machine again.
6. Install balance weight on inner side of road wheel in the balancer machine indication position (angle). CAUTION: Do not install more than two balance weights.
