11. Turn the engine off and wait more than 15minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
After the operation
1. Install the engine undercover into positionas the following steps.
a. Pull the center of the small plastic clip out.
b. Hold the engine undercover into position.
c. Insert the clip through the undercover into the hole in the frame, then push the
center of the clip in to lock the clip in
place.
d. Install the other bolts that hold the un- dercover in place. Be careful not to strip
the bolts or over-tighten them.
2. Lower the vehicle carefully to the ground.
3. Dispose of waste oil and filter properly.
WARNING
●Prolonged and repeated contact with used
engine oil may cause skin cancer.
● Try to avoid direct skin contact with used oil.
If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as
possible.
● Keep used engine oil out of reach of children. Contact an INFINITI retailer if replacement is
required.
CAUTION
●
Use only Genuine NISSAN Matic S ATF. Do
not mix with other fluids.
● Using automatic transmission fluid other
than Genuine NISSAN Matic S ATF will cause
deterioration in driveability and automatic
transmission durability, and may damage
the automatic transmission, which is not
covered by the INFINITI new vehicle limited
warranty.

CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS
9-2Technical and consumer information

Temperature conditions can also affect towing.
For example, towing a heavy trailer in high
outside temperatures on graded roads can af-
fect engine performance and cause overheat-
ing. The transmission high fluid temperature
and engine protection mode, which helps re-
duce the chance of transmission and engine
damage, could activate and automatically de-
crease engine power. Vehicle speed may de-
crease under high load. Plan your trip carefully
to account for trailer and vehicle load, weather
and road conditions.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced speed
may be lower than other traffic, which could
increase the chance of a collision. Be especially
careful when driving. If the vehicle cannot
maintain a safe driving speed, pull to the side
of the road in a safe area. Allow the engine to
cool and return to normal operation. See “IF
YOUR VEHICLE OVERHEATS” in the “6. In case of
emergency” section of this manual.
CAUTION
Vehicle damage resulting from improper tow-
ing procedures is not covered by INFINITI
warranties.
Tongue load
When using a weight carrying or a weight
distributing hitch, keep the tongue load be-
tween 10 to 15% of the total trailer load or use
the trailer tongue load specified by the trailer
manufacturer. The tongue load must be within
the maximum tongue load limits shown in the
following “Towing Load/Specification” chart. If
the tongue load becomes excessive, rearrange
cargo to allow for proper tongue load.
STI0542
9-18Technical and consumer information

3. Try to rearrange the trailer load so it isbalanced as described earlier in this sec-
tion.
●Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
● Use the Tow mode or downshift the trans-
mission to a lower gear for engine braking
when driving down steep or long hills. This
will help slow the vehicle without applying
the brakes.
● Avoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
● Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
● INFINITI recommends that the cruise control
not be used while towing a trailer. ●
While towing a trailer, do not use the follow-
ing systems (if so equipped):
– the Lane Departure Prevention (LDP) sys- tem
– the Blind Spot Warning (BSW) system
– the Intelligent Cruise Control (ICC) system
– the Distance Control Assist (DCA) system
– Intelligent Brake Assist ( IBA) system
● Some states or provinces have specific regu-
lations and speed limits for vehicles that are
towing trailers. Obey the local speed limits.
● Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.
● When launching a boat, do not allow the
water level to go over the exhaust tail pipe or
rear bumper.
● Make sure you disconnect the trailer lights
before backing the trailer into the water or
the trailer lights may burn out.
When towing a trailer, the transmission fluid
should be changed more frequently. For addi-
tional information, see the INFINITI Service and
Maintenance Guide.
TOW mode
Using TOW mode is recommended when pulling
a heavy trailer or hauling a heavy load. Push the
TOW MODE switch to activate tow mode. The
TOW MODE indicator light in the meter illumi-
nates when TOW mode is selected. Push the
TOW MODE switch again to turn TOW mode off.
TOW mode is automatically cancelled when the
ignition switch is placed in the OFF position.
TOW mode includes the following features:
● Grade logic — Adjusts transmission shifts
when pulling a trailer or hauling a load up a
grade.
● Downhill Speed Control (DSC) — automati-
cally downshifts when driving down a grade
with a trailer or heavy load to help control
vehicle speed.
Driving the vehicle in the TOW mode with no
trailer/load or light trailer/light load will not
cause any damage. However, fuel economy may
be reduced and the transmission/engine driv-
ing characteristics may feel unusual.
When towing a trailer, final drive gear oil should
be replaced and transmission oil/fluid should be
changed more frequently. For additional infor-
mation, see the 9. “Technical and consumer in-
formation” section later in this manual.
