Exam Questions and Answers
Nissan manual transmissions use double- or triple-cone synchronizers on the gears that
receive the most use, which ________. - Correct Answers --Enhances the durability of
the transmission
-Allows gears to mesh during shifting without grinding
What does hill start assist do? - Correct Answers -Keeps brakes applied so the driver
can transition from the brake to accelerator without the vehicle rolling backward
How are Nissan's truck and SUV 6-speed manual transmissions different from manual
transmissions in other vehicles? - Correct Answers -They have a very low 1st-gear ratio
that enhances off-road and towing capability
When does hill descent control operate? - Correct Answers --Only in 4H or 4LO
-When activated by the driver
-Below 15 mph
What is torque steer? - Correct Answers -The tendency for a front-wheel-drive vehicle to
pull in one direction under hard acceleration
In a front-wheel-drive vehicle, what is the transaxle? - Correct Answers -A single unit
combining the clutch, gearbox, and differential gears between the front wheels
What are the benefits of the Xtronic CVT (Continuously Variable Transmission)? -
Correct Answers --Eliminates hunting for the right gear when driving uphill
-No waiting for the transmission to downshift when passing
-Avoids shift shock and delivers smooth acceleration
What are the advantages of D-step tuning? - Correct Answers --Provides a more natural
feel during rapid acceleration
-Reduces the engine noise of constant high-rev acceleration
What's the benefit of a limited-slip differential? - Correct Answers --Automatically
distributes power to the drive-wheel that has the most grip
-Improves traction on slippery road surfaces
100% of the torque from Nissan LEAF's electric motor is available at ____ mph. -
Correct Answers -0
, What does regenerative braking do? - Correct Answers --Converts normally wasted
energy from conventional braking into electric power
-Works with the friction brakes to create outstanding stopping power
A transmission interlock prevents ________. - Correct Answers --Starting the engine
unless the clutch pedal is depressed (manual transmission)
-Shifting from Park unless the brake pedal is depressed (automatic transmission or
CVT)
In a Viscous Limited-Slip Differential, what activates the fluid in the differential housing?
- Correct Answers -Heat from friction caused by drive-wheels spinning at different
speeds
What are the ways to charge the Nissan LEAF? - Correct Answers --Standard charging
with 220/240V utility service
-Quick charging with commercial high-voltage service
What does a transmission interlock do? - Correct Answers -Prevents the transmission
from engaging accidentally
What does SynchroRev Match do for a manual transmission? - Correct Answers --
Raises engine rpm momentarily to allow faster, smoother downshifts
-Matches engine speed when upshifting allowing for faster, smoother upshifts
How does hill descent control assist the driver when traveling down steep hills at very
low speed? - Correct Answers -Applies braking action to individual wheels
What's the benefit of overdrive? - Correct Answers --Allows the vehicle to operate more
quietly and efficiently
-Promotes a more comfortable, quieter ride
-Increases economy through better fuel efficiency
What are the operating modes for the Nissan Intelligent Dual Clutch Hybrid System? -
Correct Answers --Gasoline Engine Only
-Regeneration of Energy
-Electric Motor Only
-Engine Plus Motor
What is overdrive? - Correct Answers -Gear in which the output of the transmission
turns faster than the input
How is Nissan becoming a global leader in zero-emission mobility? - Correct Answers --
Engagement with more than 80 zero-emission partnerships worldwide
-Launched LEAF, the first 100% electric mass-market zero-emission car in 2010
-Promoting recycling parts used in vehicle production
