2022 TOYOTA TUNDRA engine

1944-1. Before driving
●Slow down before making a turn, in crosswinds, on wet or slippe ry
surfaces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the lengt h of
your trailer, and be sure you have plenty of room before changi ng
lanes.
● Vehicles with an automatic transmission: To maintain engine bra k-
ing efficiency and charging system performance when using engin e
braking, do not use the transmission in D. If in the S mode, th e
transmission shift range posit ion must be in 5 or lower.
● Vehicles with a manual transmiss ion: To maintain engine braking
efficiency and charging system performance when using engine
braking, do not use the sixth gear.
● Instability happens more frequently when descending steep or lo ng
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
● Avoid holding the brake pedal down too long or applying the bra kes
too frequently. This could cause the brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may over-
heat on hot days (at temperatures over 85°F [30°C]) when drivin g
up a long or steep grade. If the engine coolant temperature gau ge
indicates overheating, immediately turn off the air conditionin g (if in
use), pull your vehicle off the road and stop in a safe spot.

Driving
●Always place wheel blocks under both the vehicle’s and the trai ler’s
wheels when parking. Apply the parking brake firmly, and put th e
transmission in P (automatic transmission) or in 1 or R (manual
transmission). Avoid parking on a slope, but if unavoidable, do so
only after perform ing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle’s and
trailer’s wheels.
When the wheel blocks are in pl ace, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into P (automatic transmission) or 1 or R (manual transmi s-
sion) and turn off the engine.
● When restarting afte r parking on a slope:
With the transmission in P (autom atic transmission) or the clutch
pedal (manual transmission) depr essed, start the engine. On
vehicles with an automatic transmission, be sure to keep the
brake pedal pressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake (and also the brake pedal on vehicles
with an automatic transmission), and slowly pull or back away
from the wheel blocks. S top and apply the brakes.
Have someone retrieve the blocks.

Driving
■Break-in schedule
If your vehicle is new or equipped with any new power train com ponents
(such as an engine, transmission, differential or wheel bearing ), Toyota rec-
ommends that you do not tow a trailer until the vehicle has bee n driven for
over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start
towing. However, for the next 500 miles (800 km), drive the veh icle at a speed
of less than 50 mph (80 km/h) when towing a trailer, and avoid full throttle
acceleration.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent m aintenance due
to the additional load. (See “Owner’s Warranty Information Book let” or
“Scheduled Maintenance Guide”/“Owner’s Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.
■ If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle and trailer, causing instability.
● If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
• Begin releasing the accelerator pedal immediately but very gra dually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. (if enabled, Trailer Sway Control can also help to
stabilize the vehicle and trailer.)
● After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle. Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred
is beyond the limit of your particular vehicle-trailer combinat ion.
Drive at a lower speed to prevent instability. Remember that sw aying of the
towing vehicle-trailer increases as speed increases.
