4937-2. Steps to take in an emergency
7
When trouble arises
HIGHLANDER HV_U
One of the following may be the
cause of the problem:
The electronic key may not be
functioning properly.
( P.496)
 There may not be sufficient
fuel in the vehicle’s tank.
Refuel the vehicle.
 There may be a malfunction
in the immobilizer system.
( P.79)
 There may be a malfunction
in the steering lock system.
 The hybrid system may be
malfunctioning due to an elec-
trical problem such as elec-
tronic key battery depletion or
a blown fuse. However,
depending on the type of mal-
function, an interim measure
is available to start the hybrid
system. ( P.494)
NOTICE
●Securely tighten the spare tire
clamp bolt to hold the spare
wheel carrier by the hook.
●Stow the flat tire in the spare tire
location. Failure to do so may
cause damage to the spare tire
carrier. Proper storage reduces
the possibility of injury in a colli-
sion or during sudden braking.
●Have the flat tire repaired and
the spare tire replaced with it as
soon as possible.
■Proper storage of the spare
tire
●If the hoist assembly is slanted
when stowing a tire, the hoist
assembly may become stuck in
the wheel opening and the tire
may not be raised properly,
causing damage to the wheel or
the wire cable.
●Do not attempt to turn the spare
tire clamp bolt without a tire on
the hoist assembly, as doing so
may cause the wire cable to slip
off of the shaft inside the unit
and the wire cable may not be
able to be raised or lowered. If
the spare tire clamp bolt has
been turned without a tire on the
hoist assembly and the wire
cable cannot be raised or low-
ered, contact your Toyota
dealer.
If the hybrid system
will not star t
Reasons for the hybrid sys-
tem not starting vary
depending on the situation.
Check the following and
perform the appropriate
procedure:
The hybrid system will not
start even though the cor-
rect starting procedure is
being followed. ( P.213)

Outside temperature
SAE 0W-16 is the best choice
for good fuel economy and good
starting in cold weather.
If SAE 0W-16 is not available,
SAE 0W-20 oil may be used.
However, it must be replaced
with SAE 0W-16 at the next oil
change.
Oil viscosity (0W-16 is explained
here as an example):
• The 0W in 0W-16 indicates the characteristic of the oil
which allows cold startability.
Oils with a lower value before the W allow for easier starting
of the engine in cold weather.
• The 16 in 0W-16 indicates the viscosity characteristic of the
oil when the oil is at high tem-
perature. An oil with a higher
viscosity (one with a higher
value) may be better suited if
the vehicle is operated at high
speeds, or under extreme
load conditions.
How to read oil container label:
API registered mark is added to
some oil containers to help you
select the oil you should use.

The malfunction indicator lamp on
the instrument cluster may come on.
If this happens, contact your Toyota
dealer for service.
■If your engine knocks
●Consult your Toyota dealer.
●You may occasionally notice light
knocking for a short time while
accelerating or dr
iving uphill. This
is normal and there is no need for
concern.
NOTICE
■Notice on fuel quality
●Do not use impro per fuels. If
improper fuels are used, the
engine will be damaged.
●Do not use leaded gasoline.
Leaded gasoline can cause
damage to your vehicle’s
three-way catalytic converters
causing the emission control
system to malfunction.
●Do not use gasohol other than
the type previously stated.
Other gasohol may cause fuel
system damage or vehicle per-
formance problems.
●Using unleaded gasoline with
an octane number or rating
lower than the l evel previously
stated may cause persistent
heavy knocking.
At worst, this may lead to
engine damage an d will void the
vehicle warranty.
■When refueling with gasohol
Take care not to spill gasohol. It
can damage your vehicle’s paint.
■Fuel-related poor driveability
If poor driveability (poor hot start-
ing, vaporization, engine knock-
ing, etc.) is encountered after
using a different type of fuel, dis-
continue the use of that type of
fuel.
